Высокоэффективный фильтр для воды удаляет 99,9% микропластика за 10 секунд.

High efficiency water filter removes 99.9% of microplastics in 10 seconds.

Korean researchers have developed a new water purification system that filters tiny pieces of plastic as well as other pollutants very quickly and efficiently. In the development, scientists used a covalent triazene framework (CTF). It is a very porous material with a large surface area. There is "enough space to store molecules," the researchers write. Such materials are effective in removing organic dyes from industrial wastewater. The team modified the molecules in CTF to better attract water and subjected the material to mild oxidation. The resulting filter proved to be very effective. It removes microplastics from water - over 99.9% of pollutants were removed within 10 seconds. The material can also be reused many times without degrading its performance. The researchers also developed a version of the polymer that absorbs sunlight, converts energy into heat, and uses it to purify water from volatile organic compounds (VOCs). This made it possible to remove more than 98% of VOCs using only solar radiation. The prototype combining both types of membranes removed more than 99.9% of both types of contaminants.

Офисная башня, полностью покрытая солнечными панелями, сама обеспечит себя энергией.

An office tower completely covered with solar panels will provide itself with energy.

The $40 million tower will feature 1,182 solar panels the thickness of a conventional glass façade. An eight-story Skala building will be built in West Melbourne, Australia. It will be the first office tower in the country to be completely covered in solar panels, marking a game-changer for the construction industry. The $40 million tower will feature 1,182 panels as thick as a normal glass façade. Now the Skala solar panel system is manufactured by the German company Avancis. When completed, the array of panels will provide enough power to meet virtually all of the building's energy needs without ongoing energy costs. The building will also become carbon-neutral in a few years, serving as a prime example of the prospects for decarbonizing the construction industry. The building's thin-film photovoltaic module will transfer the generated electricity to the tower's main power source. According to The Guardian, it can generate 50 times more power than a typical rooftop photovoltaic solar array used in residential buildings. When completed, the system will provide enough power to meet the energy needs of the entire building, preventing the emission of 77 tons of CO₂ per year. With the addition of additional roof panels, it is planned that the building will consume almost no electricity and become carbon neutral in a few years. Google Translation

«АЛЮТЕХ» представляет WIND PROTECTION для повышения ветровой устойчивости роллетных ворот.

ALUTECH presents WIND PROTECTION to increase the wind resistance of roller doors.

The ALUTECH Group of Companies presents a new patented solution for increasing the wind resistance of rolling shutters based on the AG/77 profile - the Wind Protection (WP) system. The WP system includes 3 new components: guide rail GR105×35IE (Fig. 1); side lock SP/77WP (Fig. 2); guide roller RG/WP (Fig. 3). The Wind Protection system, thanks to the new side locks with wind grips, has a number of advantages compared to the use of locks of the previous modification. Due to the fact that the design of the updated part is monolithic and does not provide for additional elements in the form of plates and self-tapping screws, the following disadvantages were eliminated: the need to adjust the locks, which increased the installation time and increased the likelihood of errors during the installation of rolling shutters; wedging / jamming of locks, which could occur if the plate of one lock hit the plate of another when winding the web; additional noise during operation due to moving metal elements. At the same time, the previous parameters of roller shutter winding are completely preserved. In addition, new engineering solutions, which were first used in the production of components of the WP system, made it possible to increase the width of the roller shutter by 15%. We are sure that the innovative Wind Protection system will prove itself as a reliable, convenient and functional solution from ALUTECH Group of Companies, which will be appreciated by the clients and partners of the holding.

ТЕХНОНИКОЛЬ представляет новый формат очистителя для ПВХ-мембран.

TECHNONICOL presents a new cleaner format for PVC membranes.

The product will be available as a spray in small 650ml bottles. This will increase the convenience of transportation and use of the cleaner. During installation and construction work, PVC membranes are often contaminated - they move on them in shoes, the wind can bring dust. Contamination negatively affects the quality of welding, therefore, membranes are usually cleaned before welding. Traditionally, cleaners are available in large canisters with a volume of 3 liters. For small local repairs or minor work, it may be inconvenient to use the product in such a bulky and heavy package. TECHNONICOL has released a spray cleaner for PVC membranes with a volume of 650 ml. Universal cleaner effectively removes grease, bitumen, traces of oil, as well as inorganic contaminants that occur during the installation and operation of a polymer roof. Leaves no residue, residue or streaks. The cleaner is easy to use - the cylinder can be held in any position, even horizontally, while cleaning and welding immediately, without waiting for the treated area to dry. A number of analogues have a rather unpleasant, pungent odor, which negatively affects the workflow. The new TECHNONICOL cleaner does not have a strong odor. The application temperature of the product is from -25 to +50°C. “We are often inspired to develop new materials and solutions by the feedback we receive from builders. It was important for us to make a product that would be comfortable to use in any conditions,” said Evgeniy Spiryakov, COO of the Polymeric Membranes and PIR division of TECHNONICOL. - The new spray fits easily into a bag or box with a building hair dryer, so it will always be at hand. At the same time, the tank itself is reliable and convenient. We hope that builders will appreciate the novelty.” Google Translation

ТЕХНОНИКОЛЬ разработала новое эффективное решение изоляции трубопроводов с помощью ПВХ мембран.

TECHNONICOL has developed a new effective solution for pipe insulation using PVC membranes.

Simple installation, vandal resistance, durability, fire safety of PVC membranes will provide long-term and reliable waterproofing of pipelines. Today, there are various options for insulating pipelines, of which one of the most popular is the use of a metal cover layer. But this solution, firstly, is not suitable for all situations. For example, it is not allowed to use a metal cover layer for underground channelless laying and laying pipelines in non-passable channels. Also, a cover layer made of thin sheet metal with an outer polymer coating is not allowed to be used in places exposed to direct sunlight. Secondly, the metal cover layer is often stolen in order to hand it over to scrap metal collection points. Thirdly, construction professionals have many questions about the reliability of waterproofing with metal. The specialists of the TECHNONICOL company have developed a modern and effective solution for insulating pipelines using PVC membranes, which can be used both in the repair and in the construction of new pipelines. The use of PVC membrane as a cover layer allows you to create a reliable and durable waterproofing resistant to various influences. The solution has a wide range of advantages, including simplicity and ease of installation - the PVC membrane is wrapped around the insulated pipeline and welded using hot air. In addition, the protective PVC membrane can be installed all year round. PVC membranes are durable. Thanks to the special additives included in the composition, the PVC membrane is extremely resistant to natural factors such as UV radiation, precipitation, frost. An important advantage of this type of waterproofing is its vandal resistance - membranes are not of interest to thieves. TECHNONICOL PVC membranes are fireproof, they are non-combustible materials and do not support combustion. Also, the specialists of the TECHNONICOL company recommend the use of cylinders and half-cylinders made of PIR insulation for pipeline insulation. This prevents the formation of condensation or freezing of the liquid in the pipeline. Due to its low thermal conductivity, the use of PIR as insulation allows reducing the thickness of the thermal insulation and saving on the amount of the covering layer. “Problems with current pipes are widely known to the population of our country. But they pose a huge problem for developers, management companies, and service organizations. Huge sums of money are spent annually on pipeline repairs. The construction of new pipelines and the repair of old ones using modern construction technologies allow achieving a long service life of pipes and significantly reducing the cost of further repairs, ”emphasized Sergey Gavrilov, Head of Technical Support, Industrial and Civil Engineering, Polymer Membranes and PIR Division of TECHNONICOL.

Из стеклянных отходов создали более прочный и качественный бетон.

From glass waste created a more durable and high-quality concrete.

Most glass waste is never recyclable as it is small fragments that are difficult to sort. A group of Australian scientists from Deakin University, led by Dr. Riyadh Al-Amery, have proposed a simple and effective way to process and further use them. Initially, the waste glass is grinded into coarse powder, which is then used instead of sand as a filler in polymer concrete. Polymer concrete, in turn, is a substitute for polymer resin, a binder commonly used in the manufacture of waterproof floors. In laboratory tests, concrete with glass powder showed higher strength compared to the traditional sand-based counterpart. In addition, crushed glass does not need to be washed and sorted, which makes the new material much cheaper. Another plus of glass concrete is that stocks of high-quality sand are rapidly declining, while huge volumes of glass waste are unclaimed.  “Worldwide, the construction industry accounts for 6% of global GDP,” Al-Ameri explains, “Concrete is still the main building material, and sand is one of its main components that needs to be replaced.” Google Translation

Построен первый завод по переработке пластикового мусора в кирпичи.

The first factory for processing plastic waste into bricks was built.

Côte d’Ivoire built the first factory to process plastic waste into bricks in its largest city, Abidjan. This factory produces recycled plastic bricks that can be used for the construction of much-needed schools in the country. This innovative initiative is the result of a partnership between UNICEF (United Nations Children’s Fund, UNICEF) and Colombian social enterprise Conceptos Plasticos. They began building a factory that will turn the plastic waste collected in Côte d’Ivoire into modular plastic bricks. Easy-to-assemble, durable and inexpensive plastic bricks are a way to minimize the environmental impact of plastic, and these bricks also help the noble cause, they will be used to build school classes in the West African country. “This factory will be at the forefront of smart, scalable solutions for some of the major educational challenges facing children and communities in Africa,” said UNICEF Executive Director Henrietta Foret. The technology will help increase the number of students in schools in Côte d’Ivoire, reduce the amount of plastic waste in the environment and provide additional income opportunities for the most vulnerable families, ”said Foret. Côte d’Ivoire needs 15,000 classrooms to meet the needs of children without a place to learn. To help fill this gap, UNICEF collaborated with Conceptos Plasticos to use recycled plastic from contaminated sites in and around Abidjan to build 500 classrooms for more than 25,000 children. “One of the main problems that Ivorian schoolchildren face is the lack of audiences. Either they do not exist, or if they exist, they are crowded, which makes learning a difficult and unpleasant experience for schoolchildren, ”said UNICEF spokesman Abubakar Campo. More than 280 tons of plastic waste are produced daily in Abidjan alone. Only about 5 percent is recycled - the rest goes to landfills. Plastic waste contamination strengthens existing hygiene and sanitation problems. Improper waste management entails 60% of cases of malaria, diarrhea and pneumonia in children - diseases, is one of the leading causes of death of children in Côte d’Ivoire. Once the factory is fully operational, it will recycle 9600 tons of plastic waste per year and provide a source of income for women who live in poverty. The bricks will be made of 100 percent plastic and will be fire resistant. They are 40 percent cheaper, 20 percent lighter and last hundreds of years longer than conventional building materials. They are also waterproof, well insulated and designed to withstand strong winds. Along with investments in construction in Côte d’Ivoire, it is also planned to scale this project in other countries of the region, and possibly beyond. West and Central Africa accounts for one third of primary school children in the world and one fifth of lower secondary children who are not studying.  “This project is more than just a waste management infrastructure project, it’s a functioning metaphor - the growing challenge of plastic waste is turning into real building blocks for the next generation of children,” Foret said.

В Литве разработали технологию производства бетона без использования цемента.

In Lithuania, developed a technology for the production of concrete without the use of cement.

Scientists of Kaunas University of Technology (KTU) in Lithuania have developed a technology for the production of concrete without the use of cement. According to them, industrial waste such as carbon black can be used to produce concrete without cement. At the same time, the final product will have strength characteristics comparable to traditional concrete. It will also be more resistant to acids and more stable in cases of exposure to high temperature and cold. Project developers claim that in the production of 1 ton of Portland cement (the main ingredient of concrete and the most commonly used type of cement worldwide), up to 1 ton of carbon dioxide enters the atmosphere. According to experts, the global cement industry annually accounts for approximately 7% of all CO2 emissions into the atmosphere. In order to reduce the negative impact of a particular industry on the environment, KTU researchers are studying methods for replacing Portland cement with other materials. “At first, the idea that concrete can be obtained without using cement seems radical. Now, after several years of intensive work, we were able to develop alkali-activated concrete, which has a compressive strength of 55 MPa - the same as in ordinary concrete. Instead of Portland cement, we use alkalized industrial waste: soot, biofuel sludge, AlF3 production waste - silica gel, etc. ” - Researcher at the Faculty of Civil Engineering and Architecture of KTU Vytautas Bokullo. Bocullo added that the biggest advantage of this type of binder is that a large amount of industrial waste containing the active form of silicon and aluminum compounds could be used in its production. He clarified that theoretically any material containing silicon and aluminum compounds, such as blast furnace slag or metakaolin, a material obtained from a modification of clay mineral kaolin, can be used. Treated with a special alkaline solution, these materials begin to melt and bind similarly to traditional cement. Depending on the composition, the final product can be either a geopolymer or an alkali-activated material. The developers said that alkali-activated concrete is much more resistant to fire and acid. In addition, since it has a higher pH, it is less susceptible to corrosion. According to Vytautas Bokullo, alkaline activated concrete can be used instead of traditional concrete in many areas, and it can become a popular alternative to traditional concrete around the world. From an economic point of view, it is more profitable, since you can use local materials. “We are trying to use local industrial waste, such as aluminum fluoride production waste - silica gel and ash from biofuels. The preparation of a substance depends on the material itself. For example, carbon black can be used instantly, but the biofuel sediment must be crushed to a fineness of cement. To improve the quality of the final product, several substances can be mixed, but before that their chemical composition and additives must be studied for environmental impact and impact on the strength characteristics of concrete ”- Vytautas Bokullo, researcher at the Faculty of Civil Engineering and Architecture of KTU. Research teams working at the Faculty of Civil Engineering and Architecture of KTU also experiment and develop other types of concrete mixes, such as superhard concrete, self-healing concrete and others.

Ученые создали метод 3D-печати из стекла разных типов.

Scientists have created a method of 3D printing of different types of glass.

Scientists from the Swiss Higher Technical School of Zurich have created a 3D printing method that allows you to create complex structures from different types of glass without heating the material to a high temperature. An article describing the study was published in the journal Nature Materials. Glass, ceramics and other similar materials are rarely used in 3D printing, because they have a relatively high melting point - from 1,650 ° C to 4,040 ° C. This makes the printing process labor intensive and expensive. Researchers have proposed a solution to the problem - their method involves the use of digital light processing. It consists in creating a blank from a glass precursor before printing, and then conducting high-temperature annealing. After that, the researchers added photocurable polymers to the solution and illuminated it in the right places. Thanks to this process, a solid object is formed in the liquid solution. Then scientists subjected the subject to pyrolysis, in which the polymer part burned out, and the glass remained. The transparency of the resulting glass is approximately 85%, and the relative density is up to 95%. Google Translation

China launches a giant wind turbine with a wingspan of 210 meters.

China is today the world leader in the development of green technologies. Paradoxically, this example is shown by the country, which is also the largest emitter of greenhouse gases. Of course, the transition to renewable energy will solve many environmental problems. Last year, offshore wind farms with a total capacity of 20.2 GW and offshore stations with a capacity of 1.6 GW were launched in the country, which is respectively 44% and 37% of the world market. And soon, in the Sichuan province in the south-west of the country, it is planned to put into operation the first giant wind generator H210-10MW with a wingspan of 210 meters. The rig was developed by HZ Windpower, a subsidiary of China Shipbuilding Industry. The turbine power is 10 megawatts. This is twice the capacity of the 5-megawatt wind turbines operating in the region. According to Han Huali, Director of the HZ Windpower Research Institute, after commissioning, each unit will be able to generate about 40 million kWh of electricity annually. Meanwhile, according to Xinhua News Agency, HZ Windpower is developing an even larger wind generator with a rotor diameter of 230 m. Google Translation

The concrete created by the researchers has properties similar to rubber - the report says that it is six to nine times more resistant to cracking than ordinary concrete. In addition, the material is self-sealing during pouring - in other words, it does not allow water to pass through, and can be used for the construction of various types of underground structures, such as bunkers. Roman Fedyuk, lead author of the study: “It was important for us that the concrete lasted until the first crack as long as possible. Today, engineers around the world are working on creating safety features that will allow the building to withstand in the event of a projectile or plane crash. We approached this issue from our own point of view, we developed impact-resistant material. At the next stage, we want to create radiation-resistant concrete. " Google Translation

Фины разработали полностью биоразлагаемый экопластик из паутины и древесных волокон.

Finns have developed a fully biodegradable ecoplastics from cobwebs and wood fibers.

Researchers warn that by 2050 there may be more plastic in the oceans than fish if the current pace of plastic production does not stop, so many environmentalists insist on introducing a truly biodegradable plastic alternative. At first glance, the combination of strength and toughness in one material seems unlikely, however, a new substance obtained by mixing wood fibers and cobwebs makes this quite possible. To create new experimental material, scientists at Aalto University and VTT Technical Research Center (Finland) used birch pulp, which was split into tiny fibers - cellulose nanofibrils. Then, an adhesive (a substance capable of combining materials by surface adhesion) from the web was added to the resulting mass, resulting in a soft, energy-dissipating matrix, consisting of nanofibrils aligned in the direction. Studies have shown that the new plastic “surpasses most modern synthetic and natural materials” in its properties by its ability to resist irreversible deformation and fracture loads. In addition, unlike some types of plastic with similar properties, the new material is completely biodegradable. Unfortunately, it is rather difficult to obtain an artificial analogue of the web on an industrial scale. Unique material can find practical application in the production of implants, textiles, packaging and impact-resistant items. Google Translation

Астронавты замесили бетон в космосе.

Astronauts kneading concrete in space.

In the future, people will explore outer space, and they will have to build homes on other planets. The crew of the International Space Station created concrete in orbit. This writes the press service of the United States Aerospace Administration. As part of the Microgravity Cement Hardening Study (MICS) project, space researchers first mixed tricalcium silicate (C3S) and water under zero gravity. The main mineral component of most commercially available cement, C3S, controls many of its chemical reactions and properties. MICS has investigated whether solidification of cement in space will lead to unique microstructures. Then, scientists compared cement samples from the Earth and those obtained under microgravity conditions. A significant advantage of concrete is that theoretically it can be made using resources available on extraterrestrial bodies, like regolith on the moon. This eliminates the need to transport building materials to the moon or Mars, significantly reducing costs. Google Translation

Кирпичи и бетон заменят легким и доступным биоматериалом.

Bricks and concrete will be replaced with light and affordable biomaterial.

Bricks and concrete can be replaced with light and affordable biomaterial, for the production of which it is enough to mix sand, water and bacteria. Perhaps in the near future, bases and runways in hard-to-reach places will be built in exactly this way - from local mud. The military sometimes has to build new air bases in hard-to-reach places, where it is not easy to deliver people and equipment. Specialists from Blue Horizons, the research center of the US Air Force, intend to facilitate this task. They proposed an unusual idea: not to build runways and other infrastructure, but to grow them with bacteria. In working on a project called Medusa, Blue Horizons is collaborating with BioMASON, a biomass company. Its employees learned how to turn sand and soil into solid materials by simply mixing them with nutrient-rich water and adding special bacteria. As the microorganisms grow, they produce calcium carbonate crystals that bind sand grains together. Filling the forms with such a mixture, you can get durable bricks suitable for construction. Blue Horizons hopes that the biomaterial will be able to replace not only bricks, but also concrete - for example, as a cover for the runway. The first experiments, including the creation of a prototype with an area of 230 square meters, confirmed that the technology is suitable for use outside the laboratory and does not require additional modifications. Biosynthesis will significantly reduce the number of people and equipment necessary for the construction of air bases. And as building material it will be possible to use local dirt. However, it is not yet clear how long it will take to grow an entire airfield. Google Translation

Новая полиэтиленовая пленка, прочная как металл, заменит обычное стекло.

New plastic film, durable as metal, will replace conventional glass.

One of the latest developments of scientists at the University of London in Warwick and Queen Mary University of London is a plastic film whose strength is comparable to aluminum. At the same time, the weight of the new material is significantly less than the metal. The researchers argue that the film can be used instead of glass in various designs, as displays, windshields in cars. Ordinary glass has a significant mass and is fragile. An alternative to it can serve as polycarbonate and plexiglass, however, these materials are not strong enough. Produce films with improved mechanical properties allows the process of hot drawing high density polyethylene. The essence of this technology is in pulling blanks through a tapered hole in an instrument called a die. However, materials produced in this way do not have the required optical transparency. Some success was achieved with the use of special additives that are capable of providing transparency of 90% (with good strength properties of the film). British scientists have gone even further - they have developed a new technology that guarantees both high transparency (comparable to traditional glass) and durability of the material. And this without any additives! Studies have shown that the required characteristics can be achieved by hot drawing at temperatures from 90 to 110ºС. Interestingly, the resulting highly transparent films have a maximum longitudinal elasticity of 27 hPa and a tensile strength of 800 MPa. This is 10 times higher than that of polycarbonate and plexiglass. For comparison: the longitudinal elasticity of aluminum is 69 hPa, and the aerospace alloy based on it has the ultimate strength of 500 MPa. The density of polyethylene is 1000 kg / m³, aluminum - about 2700 kg / m³. This means that the mass of the new material will be significantly less than the metal.

Для очистки городского воздуха в Испании запустили автобусы с садами на крышах.

For the purification of urban air in Spain, they launched buses with roof gardens.

The municipal services of Madrid decided to improve the quality of urban air, and for this purpose a rather original solution was chosen. It was decided to entrust the mission of “cleansing” to one of the main culprits of pollution - route buses. The proposed initiative was called "Move in green" (Muévete en verde) and involves placing gardens on the roofs of buses, as well as on the bus shelters. According to the authors of the idea, its main task is to reduce the negative impact of public transport on the air in the capital of Spain. According to the project director Jose Antonio Antono, the choice of routes is due to the fact that they ply along the “strategically important axis between the north and south of the city, which passes through the most visited by tourists and Madrid residents and along which the most emblematic buildings and monuments are located”. During the year, a total of 17 million passengers used these routes. Project developers are planning to place green areas along the route of buses, the length of which is 30 kilometers. For this, it is planned to use more than 130 station complexes. Google Translation

В Дании разработали тротуарную плитку для сбора и повторного использования дождевой воды.

In Denmark, pavement tiles have been developed to collect and reuse rainwater.

Studioul de arhitectură danez Tredje Natur a instalat un sistem de pavaj din strada din Copenhaga, care are drept scop drenajul și crearea de spații verzi. Ploile puternice și prelungite duc adesea la probleme legate de circulația pietonală și rutieră, ducând la deteriorarea sistemelor de canalizare. Compania daneză a găsit o soluție la aceste probleme dezvoltând plăci de pavaj care absorb absorbția excesului de apă și o direcționează către plantele și copacii din apropiere. Acest proces nu numai că îndepărtează apa de pe șosele și străzi, dar permite și utilizarea sa fără a trece prin sistemul de tratare a apelor reziduale și de scurgere a canalului. Clima Tile este un produs al companiei daneze TREDJE NATUR, care atrage atenția oficialilor municipali la nivel internațional. Copenhaga a instalat deja primele dale de climatizare de 165 de picioare pentru a economisi apă și bani pentru oraș. Alte orașe au manifestat, de asemenea, interes pentru noua tehnologie. Plăcile funcționează prin crearea unei suprafețe permeabile asemănătoare crustei pământului. Gauri mici în țiglă permit apelor să se scufunde în pământ și să curgă în acvifere artificiale. Apa poate rămâne în depozit pentru utilizare ulterioară sau poate fi trimisă pentru a iriga pajiști și copaci din apropiere. Produsul este testat pentru a identifica performanța pe termen lung în funcție de diferitele tipuri de vreme în timpul anotimpurilor, greutăți în greutate, înfundarea, uzură și altele. Proiectul pilot de la Copenhaga a pus bazele unei posibile utilizări a plăcilor climatice, iar acum compania se concentrează pe găsirea unui mod de a distribui produsul pe piețele de masă din întreaga lume. Acest lucru este realizat cel mai eficient în timpul actualizărilor programate ale țevilor și conductelor pentru a reduce la minimum lucrările suplimentare de drumuri. În ciuda faptului că țiglele oferă economii de cost atât pentru consumul de apă, cât și pentru eliminarea daunelor provocate de inundații, obiectivul principal al companiei este de a dezvolta o soluție pe termen lung și durabilă pentru adaptarea continuă la climă, astfel încât țiglele au o durată estimată de viață de 50 de ani .

Канадская фирма разработала для умного города «дождевик» для зданий и умные тротуары.

Canadian firm has developed for the smart city "raincoat" for buildings and smart sidewalks.

Canadian engineering firm Sidewalk Labs is testing a tension “rain cover” for buildings made of a thin plastic membrane. An experimental prototype design installed on one of the office buildings in Toronto. The special structure of the "rain coat" is designed to protect buildings, pavement and, of course, pedestrians from wind, rain and snow. The whole year the development team will test the performance of the technology. According to the analysis of the company, such a raincoat will help reduce the energy consumption of buildings and, as developers hope, will double the amount of time people can comfortably spend on the street. When working on a project, the company's engineers have developed several architectural concepts that will help make the extreme weather in the winter months more comfortable. Then climatologists conducted a computer simulation of weather conditions and selected the most successful and efficient technology. Structural design of the design took Italian firm Maffeis Engineering. Stretch "raincoat" is made using ETFE - a polymer material that has a high resistance to high temperatures and radiation, does not lose its properties during prolonged light and atmospheric exposure. This light and transparent material is mounted at an angle on the sides of the buildings, thus protecting not only the building, but also the pavement from precipitation. In addition to the rain cover, Sidewalk developers are also testing their smart paving system. The modular system developed by the company in the form of hexagonal concrete slabs can quickly absorb rainwater, equipped with a heating system for cleaning the pavement from snow and ice. An LED light is built into each slab, which can be used to inform pedestrians about obstacles, approaching vehicles, road closures, etc. All of these technologies were developed as part of a project to create a smart city block in downtown Toronto.

Recycling plant in Poland, an example of solving the problem of recycling.

The entire civilized world has been recycling garbage for a long time. EU member states decided that by 2030 no more than 10% of waste should be stored in landfills. How the problem of garbage is solved in Poland, how much people pay for recycling and why it is important to sort the garbage. The waste management complex in Zary has been operating for three years. This company picks up trash from two dozen villages and towns, where about 200 thousand people live. The plant processes 60 thousand tons of waste per year. Each resident pays 12.5-19.5 zł per month for the removal and processing of garbage (UAH 92-143). The first tariff is for sorted garbage, the second - for unsorted. “When the system was introduced, 80% of residents declared that they were ready to sort the garbage and pay less. However, not all approach this responsibly. The question arises: to fine them immediately or send them very correctly in the right direction, ”says the first deputy mayor, Jarov, Patrick Falinski. According to him, if a resident has signed a document that he will sort the garbage, but does not do it after that, then the authorities are obliged to punish him. The plant near the 40 thousandth city of Zary copes with mixed and sorted waste. Before entering the territory, each garbage truck is weighed, after which it unloads waste into the warehouse. Tractor trash loaded into an automatic device that breaks the package and feeds waste on a special line. There begins the process of sorting. Most factory processes are automated, but some operations need to be performed manually. On the first sorting line, only two people are involved, who take large-sized items from the conveyor. In special containers, workers dump large glass, metal and wood waste. This is done so that such items do not block the sieves that separate the waste. The workflow in the enterprise is controlled by the line operator using a video surveillance system. Every morning, workers check the system for faults and report it to the operator. If all is well, he starts the line. Dozens of conveyor belts and special separators are located in the “heart” of the plant, which “select” their type of garbage. At this stage, waste is sorted into several fractions: paper, cardboard, glass, plastic, cans. This raw material can be used again, so it is sent to the enterprises for deep processing. Organic waste cleared from metal is sent to special closed tunnels. Here the garbage turns into compost. “The fermentation process lasts three weeks, the same time is needed for composting, that is, enrichment with oxygen,” says the plant technologist. Four more weeks the stage of maturation of the material continues. “Subsequently, it is crushed, packaged and sold for sale in retail chains as a fertilizer for gardens and orchards,” he adds. Interestingly, there is no unpleasant odor around the plant - exhaust air is passed through special biofilters, which are replaced every three years. “Due to the modern equipment of the plant, 20-25% of waste remains after processing at the dump,” says the director of the complex. He adds that in Poland this figure is about 60%.  Google Translation

Most of the large streets of large cities are crowded with transport. The result is an increasing level of pollution, an increase in the concentration of nitrogen dioxide, and a slower speed of movement. The trend will only worsen as the world urbanizes. It is expected that by 2050 more than two thirds of people will live in cities, many of which are megacities with a population of more than 10 million, reports the Financial Times. Partner PA Consulting, which focuses on transportation and mobility, Warwick Goodall believes that the situation can and should be changed. So far, many cities impose only restrictions on the movement of cars in the city, as was the case in Paris, Marseilles or Barcelona. But new technologies may bring more radical changes. Micro-mobility, including electric scooters and bicycles, is seen as a potential solution for more efficient movement of people around cities. Dozens of startups, including Bird, Lime, Voi and Bolt, filled cities with electric scooters, which can be rented for a minute. In a recent survey, about 34% of motorists in Portland, Oregon, said they used a scooter instead of driving a personal car or ordering a taxi. However, the safety of movement on scooters makes urban planners hesitate. More than 1,500 people were injured while riding scooters in the US in 2018, according to Consumer Reports estimates. In order for scooters to "work", cities will have to create safer roads for them - perhaps high above city streets. The BMW Group and China University of Tignes, meanwhile, have developed ambitious plans to create a network of covered pipes above the streets for scooters and bicycles. They say several cities have shown interest. Electric, self-driving cars can also radically change the appearance of cities. Fully autonomous cars can free up a lot of space, allowing you to make the streets already thanks to high accuracy of movement. American technical entrepreneur Elon Musk plans to build a series of hyperloop tunnels under several US cities where passengers will be transported at high speeds in capsules inside vacuum tubes. Meanwhile, companies such as Uber and Lilium are planning fleets of flying taxis, electric airplanes that can take off and land vertically from the landing modules scattered throughout the city. Lilium's commercial director, Remo Gerber, says that several cities interested in pilot programs have already approached the company, partly because flying taxis are a potentially cheaper alternative to traditional infrastructure, such as bridges, bypasses and railways.

Необычная скамейка остается сухой после дождя.

Unusual bench remains dry after rain.

Rainfall is one of the phenomena of nature for which we love summer. After it, the air is clean and fresh, the streets seem to glow, small droplets of sapphires hang on the leaves of the trees, and in the puddles the sun looks out, and, of course, the rainbow. It's time to sit down and admire the updated colors, inhale a heady ozone. But the benches and benches after the rain, of course, wet. What to do? A team of young Korean designers from Sungwoo Park studio found a very elegant solution to the problem. They created a two-sided bench Rolling bench (in translation - "Rotating seat"), the canvas of which can be scrolled with the help of a special pen located on the side in a metal base. The movement is carried out by a simple mechanism located inside the bench. Approaching such a bench after the rain, you just need to turn the knob several times, and the wet side will change to dry. In the meantime, you sit, wet surface has time to dry. The properties of such a non-standard bench can be useful even if one of its sides is dirty or painted. Google Translation

В крышки канализационных люков интегрируют антенны сети 5G.

5G network antennas are integrated into manhole covers.

The 5G system has excellent bandwidth, but poor connectivity when it comes to urban development. The signal in the millimeter wave spectrum, at frequencies above 30 GHz, is inhibited on any surface. Even in order to contact the receiver around the corner of the building, it is sometimes necessary to install a repeater there. The solution to this problem required ingenuity. The easiest way out of the situation is to form a network of many small cells, so that at every point in space taken it is not necessary to transmit a radio signal far away. However, even by approximate calculations, this means the need to place around the world 13.1 million new transmitters, in addition to the existing ones. Making them is not a problem, but where in the dense urban development to find a place to install this whole mountain of equipment? Engineers of the British communications company have proposed an original solution: to integrate antennas into manhole covers. First, do not have to dig trenches, spoil the landscape or build up the roof. Secondly, the hatches are located in open places and quite often. Thirdly, the technology is already successfully used in 4G networks, so adaptation for 5G is a question of technology. There are also disadvantages to this solution. To begin with, the hatches themselves will have to be redone, as the massive metal structure interferes with the signal. Further, engineers refuse to tell how many hatches, where and in what configuration they use for 4G.

Transparent wood replaces glass.

Previously, it was possible to make wood transparent only in small pieces - for example, for experiments. Researchers from China have improved and scaled the technology. At the end of the last century, botanists learned how to make wood transparent. However, when cooking in bleaching solutions we are talking about small pieces. China decided to improve the technology, making it commercially successful and much more environmentally friendly. Instead of boiling wood in bleach, the scientists steamed it with hydrogen peroxide, and then poured it with a transparent resin. This, as the authors emphasize, effectively destroys the fibers of lignin, which make the tree opaque. In addition, steaming instead of boiling better preserves the cellular structure of the material, which makes the final product more durable. At the exit, the researchers turned out panels of transparent wood, larger, thicker and more transparent than ever. Now the team has to test the mechanical properties of the material in real conditions and check the scalability of the technology. If successful, transparent wood can replace glass in many areas.

В США запустили первую плавучую систему Ocean Cleanup для очистки океана от пластика.

In the United States launched the first floating system Ocean Cleanup to clean the ocean from plastic.

In the United States launched the first floating system Ocean Cleanup, which will clean the ocean from plastic debris. The principle of its work was invented by the Dutch inventor Boyan Slat. The Ocean Cleanup company launched a trial version of an ocean cleaning system near the coast of California that will be able to extract about five tons of plastic waste a month. To collect plastic, the company will use 600-meter U-shaped floating barriers that trash garbage. The company has already launched the first barrier, then plans to launch - a whole fleet of 60 vehicles. It is assumed that in just five years this way it will be possible to remove up to 50% of the waste from the ocean, and by 2040 - 90%. In the future, The Ocean Cleanup will establish cooperation with other companies that will recycle plastic and produce new products from it. The cost of one barrier is about $ 25 million. This amount includes the cost of monitoring it during one year of operation. The Ocean Cleanup was founded five years ago by Boyan Slat, a young inventor from the Netherlands, who at that time was only 18 years old. In 2018, he received the title of "European Entrepreneur of the Year." According to the Meeting, he realized the scale of pollution of the World Ocean at the age of 16, when he was diving in Greece. The gathering noticed that plastic bags in the water float more than fish. The system has already passed tests and proved its stability while working in the turbulent waters of the Pacific Ocean.

Un cuplu a plantat 4 milioane de copaci.

Brazilian photographer Sebastián Salgado and his wife, Lelia Deluise Vanik Salgado, decided to test what a small group of passionate and dedicated people can do. In the 1990s, exhausted physically and emotionally after working to thoroughly document the horrific barbarism of the genocide in Rwanda, Salgado returned home to his native region of Brazil, which was once covered with dense rainforests. He was shocked and devastated when he discovered that the area was now barren and devoid of wildlife, but his wife, Lelia, convinced him that past glory could be restored to the landscape. “The earth was just as sick as I was after the experience in Rwanda — everything was destroyed,” Salgado told The Guardian in 2015 in an interview with the British newspaper. The photographer recalls that only 0.5% of the territory was covered with forest. “Then my wife had an incredible idea to plant the whole forest again!” “And when we started planting trees, insects and birds returned, and I also seemed to be born again - this was the most important moment,” the photographer emphasizes. Together, Sebastian and Lelia founded the Instituto Terra, a small organization that has planted 4 million seedlings since 1990 and revived wildlife. “There is one creature that can convert CO2 to oxygen — it’s a tree. We need to plant forests. Collect local tree seeds and plant again. Animals and insects will return as soon as the house is for them, ”says Sebastian. 20 years of titanic efforts to restore the local forest has paid off with a vengeance: in the place of the former deathly silence now birdsong and the buzz of insects are heard. In total, about 172 bird species returned to the forest, 33 mammal species, 293 plant species, 15 reptile species and 15 amphibian species — a whole ecosystem restored from scratch! The project of the caring Brazilian photographer and his wife inspired millions by providing a concrete example of positive environmental actions and demonstrating how quickly the environment can be restored with the right approach.

Солнечные панели в виде самоклеящейся пленки можно наносить на любые поверхности.

Solar panels in the form of a self-adhesive film can be applied to any surface.

A research team led by Xiaolin Zheng at Stanford University was able to develop unique solar panels. These batteries are made in the form of a self-adhesive film that is easily applied to various kinds of surfaces. It was Xiaoling Zheng’s father who pushed her into this idea, which once remarked that it would be good to cover not only the roof surface with solar panels, but also the entire building. The whole essence of this experiment is to immerse nickel in water, along with graphene, on which it is grown (it is a nanomaterial, which is formed by a layer of carbon atoms and contains one atom in thickness). Nickel settled on a plate of silicon and separated under water from its surface along with graphene. And it was this that formed the basis for the fact that a flexible ultra-thin solar panel was created (which receives energy from any surface). Speaking of standard solar panels, they are made on glass or silicon wafers. Therefore, we can say that they become quite heavy. So, we have a very limited place to use this kind of panels. You can also add that the necessary flexibility of the panel give it plastic and paper, but they do not have sufficient strength. As a basis, Zheng suggested using the same glass or silicone surface, except that you need to lay a layer of metal between the panel and the base. After soaking the resulting “cake from the leaves” in water (within a few seconds), the metal layer separates from the surface. What can we say about the result, then the working solar panel is only a few microns thick. Now, thanks to this thickness and high flexibility, the resulting material can be placed on any surface and even on a mobile device (that is, solar energy can be obtained from any surface). Well, at the expense of the amount of energy produced, Zheng ultra-thin panels produce this energy in the same exact amount as their rather cumbersome as well as tough “brothers”. However, in the presence of the production is a huge savings and less labor-intensive installation. The advantages can also be attributed to the fact that silicon wafers can be reused, because after it they remain completely clean. Google Translation

Чудо-машина превращает пластик в бензин.

Wonder machine turns plastic into gasoline.

An amateur engineer from France created a machine that turns plastic waste into real diesel and gasoline. According to the inventor, the machine can help mankind in the fight against the pollution of the planet. About 260 million tons of plastic are produced annually in the world, of which about eight million tons fall into the oceans, negatively affecting the habitat of underwater creatures and human activity. Amateur engineer Christopher Kostes tried to contribute to solving the global pollution problem. Inventor developed and presented a useful machine called Chrysalis, which is able to process plastic and turn it into diesel fuel and gasoline. In general, the device is a furnace in which waste is divided into small pieces and melted at a temperature of 450 degrees Celsius. “The results of the process are amazing. Produced diesel, gasoline and carbon vapors, which can be used for dyes. A kilogram of plastic gives a liter of liquid, one part of which is fuel and the other part is gasoline, ”Kostes explained. Until now, the machine is not fast enough to process large volumes of waste. According to the researcher, he is able to fix this problem and turn 50 kilograms of plastic into fuel every 80 minutes, but this will require additional funding from the authorities. At the same time, the specialist is confident that the plastic recycling project has great prospects.

Голландский стартап создает уличную мебель из мусора.

A Dutch startup creates outdoor furniture out of the trash.

Statistically, one resident of Amsterdam creates 23 kg of plastic waste per year. If you take the garbage from three, then you can recycle it and make a large universal park bench using 3D printing. And this is only the beginning, say the creators of the project “The New Raw”. The idea is very simple - do not dispose of the ubiquitous plastic waste, and immediately grind them to large granules, then to extrude to print for the urban infrastructure everything you need. Benches, fences, curbs, pillars, flowerpots for flower beds, decorative and functional elements. If you do not skimp and spend 50 kg of plastic on one product, it will come out no less durable than wood. The bench prototype has a length of 150 cm and a width of 80 cm, it can support four people. Here it is, the highlight of the venture: do not just recycle plastic, but create a short recycling loop, fully realizable in one city. In order not to carry the garbage, (he is the raw material), back and forth. Prospects for products printed from garbage for the city are the broadest, from decorating parks to modular repairs of infrastructure facilities. In fact, the Dutch seriously believe that a large-format 3D printer will become a new artist's brush and people will be able to create what is difficult to imagine today. The stuff is actually free - trash!

Создано инновационное напольное покрытие — «живая» плитка.

Created innovative flooring - "live" tile.

На строительном рынке появилось инновационное напольное покрытие, — так называемая, «жидкая», или «живая» плитка. Из чего сделана такая новинка — интерактивная поверхность пола, действительно ли она «живая», как ее можно применить в дизайне квартиры или дома? Интерактивная поверхность — элемент дизайна или полноценное напольное покрытие Одной из последних оригинальных инноваций в дизайне стала жидкая плитка — необычная вариация напольного покрытия. Новинка настолько не похожа на статичную керамическую классику, что уже получила дополнительные названия — интерактивная поверхность и живой пол. Если принять во внимание известный постулат, что движение — это жизнь, то да — жидкая плитка действительно может считаться «живой». Рисунок интерактивного покрытия под давлением начинает меняться, преображаться, расходиться волнами. Неудивительно, что такая оригинальная деталь, более всего, востребована в интерьерах развлекательных помещений — кафе, баров и дискотек, детских комнат в торговых центрах. Незаезженный дизайн заслуженно привлекает внимание посетителей любого возраста. Чем объясняются волшебные преображения жидкой плитки Живая плитка сделана по принципу сложного бутерброда, куда входит много компонентов: базовый слой, амортизирующая подложка, светоотражатель, гелевый наполнитель и т. д. Поликарбонат, используемый для производства жидкого пола, несколько отличается от привычного сотового материала для покрытия теплиц и беседок. Здесь, применяются две пластины из монолитного поликарбоната — самого прочного на данный момент полимера. Верхняя и нижняя пластины герметично соединяются между собой с помощью технологии сплавления. По внутреннему периметру каждой плитки обязательно располагается компенсационный паз, куда попадают излишки геля. Такая конструкция гарантирует отсутствие протечек даже при большой нагрузке. «Волшебником», организующим преображение поверхности, выступает специальный цветной гель. Зачастую, наполнители нескольких цветов соседствуют, не перемешиваясь между собой, благодаря специальным линзам. Под давлением, слои геля растекаются в разных направлениях, создавая эффект движения. Благодаря амортизирующему слою и гелевому наполнителю, поверхность живой плитки очень мягкая и теплая на ощупь. По ней приятно ходить босыми ногами, поэтому, жидкий пол часто укладывают в ванных, спальнях и детских комнатах. Однако, полноценного напольного покрытия из интерактивных плиток не получится — при укладке неизбежна подрезка по размеру помещения, а нарушение герметичности приводит к вытеканию геля. Да, и стоимость новинки, пока, доступна немногим, так что, живой плиткой «разбавляют» стандартные ковролин, паркет или ламинат. Плюсы и минусы живой плитки Живой плиткой можно выкладывать отдельные участки помещения, комбинируя ее с другими напольными покрытиями. При укладке, важно учесть совместимость материалов по некоторым параметрам: — жидкую плитку нельзя резать и повреждать; — нельзя подвергать одновременному давлению больше половины поверхности — это может привести к протечке, поскольку гелю просто некуда будет деваться; — нельзя эксплуатировать плитку при температуре выше +60 и ниже 0 градусов; — жидкая плитка — одно из самых дорогостоящих напольных покрытий. Одна только подвижность живой плитки, способна стать изюминкой любого интерьера, однако, дизайнеры-разработчики пошли дальше, используя не только игру цвета, но и различные подложки под гелевый компонент: — белая для усиления контраста; — прозрачная для создания эффекта воздушности; — полупрозрачная чаще всего комбинируется с использованием подсветки; — цветная обеспечивает оптимальное сочетание тонов и оттенков; — подложка с 3D пленкой многократно усиливает эффект движения. Жидкая плитка — интерактивный пол у вас дома В качестве дополнительного декора, в гель могут добавляться блестки, звездочки-люминофоры и другие компоненты. Жидкая плитка отличается еще и тем, что дает возможность создавать временный декор интерьера. Для временной фиксации, может быть использован обычный двусторонний малярный скотч — маленькие кусочки наклеиваются по периметру плитки, а при демонтаже удаляются. Как укладывать жидкую плитку Технология укладки на постоянной основе довольно проста и не требует особых навыков. Монтаж производится в несколько этапов: —  Подготовка основания. При укладке жидкой плитки важно обратить внимание на два параметра — твердую поверхность и отсутствие перепадов по высоте и уклону. Любой, даже самый незначительный уклон, нарушит равномерность распределения цвета и снизит эффектность плитки. —  Грунтование поверхности — для усиления адгезии с клеящими составами. —  Укладка плитки. Производители рекомендуют использовать для укладки уже готовые смеси для ПВХ покрытий, строго следуя инструкции. Для укладки жидкой плитки на большой площади, могут быть использованы металлические профили — такая технология позволит монтировать и демонтировать плитку многократно: — П-образный профиль укладывается по периметру, в его паз крепится плитка; — Н-образный профиль служит для состыковки двух плиток. Швы в плитке при необходимости герметизируются нейтральным силиконовым герметиком, профессионалы, также, могут использовать метод сварки ПВХ шнуром (применяется в помещениях с повышенными требованиями к прочности покрытий). Не рекомендуется проводить укладку жидкой плитки под прямыми солнечными лучами — сильный нагрев может привести к расширению и деформации. Если же попадание солнца неизбежно, нужно оставить небольшие зазоры по периметру каждой плитки — для сжатия и расширения пластика. Хранить плитку можно только в горизонтальном положении, на идеально ровных поверхностях. Нестандартное применение интерактивного пола Хотя разрабатывалась жидкая плитка, исключительно, как напольное покрытие, дизайнеры с радостью ухватились за новую идею и стали использовать ее для нестандартной отделки помещений. В принципе, живой плиткой можно декорировать любую поверхность, нужно лишь соблюдать несколько условий: — Поверхность должна быть горизонтальной — на поверхности с уклоном и уж тем более на вертикальной гель просто-напросто сползет в одну сторону; — Поверхность должна подвергаться давлению –иначе интерактивная плитка не сможет проявить свой эффект; — Поверхность не должна нагреваться выше 60 градусов — именно при такой температуре плитка начинает плавиться; — Поверхность не должна подвергаться механическому воздействию — любой порез или деформация может привести к повреждению верхнего слоя плитки и вытеканию геля. Чаще всего, живая плитка используется в декоре столешниц, подоконников, барных стоек. В качестве напольного покрытия, она идеально вписывается в необычные интерьеры ванных, добавляет задора в детские комнаты и привлекает к себе внимание в гостиной.

Японцы создали самый экономный душ в мире, расход воды 20 литров на две недели.

The Japanese created the most economical shower in the world, water consumption of 20 liters for two weeks.

Japanese startup Hotaru has created a traveling shower booth that allows you to reuse the same volume of water. The current prototype of a portable shower installation with recycling was presented at the annual SXSW festival in Texas and, according to the authors of the project, it is designed to translate the concept of “Water Freedom for Everyone, Everywhere” into reality. The idea is to install and use such a shower could be anywhere, and its main feature is the ability to carry out a hygienic procedure with minimal water consumption. And for his work does not require connection to any plumbing, and as a source of energy, you can use an ordinary car. According to the creators of the eco-soul, a volume of 20 liters of water will be quite enough for a family of three to take a shower daily for two weeks (provided that it takes no more than five minutes to “wash”). Without a special water treatment system that re-uses up to 98% of the liquid, this would take more than 840 liters of water. In addition, the mobile shower is equipped with a set of sensors that inform the user about the need to replace the water. To show what a walking shower can do, Hotaru representatives defiantly bathed in it at the SXSW festival. The portable shower cabin in the traveling version is completely folded into the pan and placed in the trunk of most cars, and to operate the pump, it is enough to connect the Hotaru to the car's battery - however, in this case it will only take a cold shower. In order to work in the shower built-in water heater, the device must be connected to a household outlet. In the future, the authors of the project hope to find an effective solution for using the shower in conjunction with solar panels or any other renewable energy source.

Норвегия перерабатывает 97% всего используемого пластика.

Norway processes 97% of all plastic used.

The Norwegian authorities, using technology from Infinitum, have created one of the most efficient and effective plastic recycling systems in the world. Today, the country processes 97% of the total plastic used, and most of it is released onto the market again. The technology allows the country to process 97% of all plastic, especially plastic bottles, 92% of which allow them to be reused for bottling. No more than 1% of the total plastic used in the country is released into the environment. The technology allows you to use the same plastic bottle at least 50 times. At the same time in the USA the level of processing of plastic bottles is no more than 30%, and in the UK - 20%. In the traditional production model, it is cheaper for business to create a new plastic than to recycle the old one and use it. In Norway, when buying a plastic bottle, people pay a tax for using it at about $ 0.3. You can get them back by handing this bottle in a special vending machine. So in many European countries take glass bottles - this allows you to increase the amount of sorted garbage. In addition to working with customers, the authorities introduced an environmental tax for plastic manufacturers. A business can avoid it only if it uses recycled bottles more than new plastic products.

Ученый из Испании разработал светоизлучающий цемент.

A scientist from Spain has developed a light-emitting cement.

For lighting roads and sidewalks, as well as buildings without electricity, Dr. José Carlos Rubio of the University of Michoacan in San Nicolas Hidalgo, Mexico, proposes a new light-emitting cement that has a service life of 100 years. Dr. Rubio began developing new material 9 years ago. As is known, when ordinary powdered cement is dissolved in water, insoluble flaky crystals are formed, which are considered to be one of the types of defects and negatively affect the strength characteristics of the finished concrete. In order to eliminate the very possibility of the formation of these crystals and to make the cement solution more homogeneous, the researcher changed the microstructure of the cement and added fluorescent components to the material that can absorb solar energy and return it to the environment in the form of radiating light. During the day, any structure made of new material can absorb solar energy and then emit it at night for 12 hours. As Dr. Rubio notes, most fluorescent materials are made of plastic and have a short lifetime (about three years) due to the negative effects of ultraviolet radiation. New fluorescent cement is highly resistant to UV rays and has an estimated lifespan of 100 years. In addition, the cement slurry with fluorescent particles is more environmentally friendly, as it is made using natural materials, chalk and clay, the only by-product of cement production is water vapor. At the moment, Dr. Rubio has developed a blue and green-emitting cement, while the intensity of the light can be adjusted to avoid blinding drivers or cyclists.

Разработана технология производства бетона без использования цемента.

A technology has been developed for the production of concrete without the use of cement.

Scientists of Kaunas University of Technology (KTU) in Lithuania have developed a technology for the production of concrete without the use of cement. According to them, industrial waste, such as coal soot, can be used to produce concrete without cement. At the same time, the final product will have strength characteristics comparable to traditional concrete. It will also be more resistant to acids and more stable in cases of exposure to high temperature and cold.The project developers claim that in the production of 1 ton of Portland cement (the main ingredient of concrete and the most commonly used type of cement throughout the world) up to 1 ton of carbon dioxide is released into the atmosphere. According to experts, the global cement industry annually accounts for about 7% of all CO2 emissions to the atmosphere. In order to reduce the negative impact of a particular industry on the environment, KTU researchers are studying methods for replacing Portland cement with other materials.“At first, the idea that concrete can be obtained without the use of cement seems radical. Now, after several years of intensive work, we managed to develop alkaline-activated concrete, which has a compressive strength of 55 MPa - the same as in ordinary concrete. Instead of portland cement, we use alkalized industrial waste: soot, biofuel sludge, AlF3 production waste - silica gel, etc. ”- researcher of the Faculty of Civil Engineering and Architecture of the KTU Vytautas Bokullo.Bokullo added that the biggest advantage of this type of binder is that a large amount of industrial waste containing the active form of silicon and aluminum compounds could be used in its production. He clarified that theoretically any material containing silicon and aluminum compounds, such as blast furnace slag or metakaolin, a material obtained from the modification of a clay mineral kaolitine, can be used.Processed with a special alkaline solution, these materials begin to melt and bind, just like traditional cement. Depending on the composition, the final product can be either a geopolymer or an alkali-activated material. The developers said that alkaline-activated concrete is much more resistant to fire and acid. In addition, since it has a higher pH, it is less susceptible to corrosion.According to Vytautas Bocullo, alkaline activated concrete can be used instead of traditional concrete in many areas, and it can be a popular alternative to traditional concrete throughout the world. From an economic point of view, it is more profitable, as you can use local materials.“We are trying to use waste from local industry, such as aluminum fluoride production waste - silica gel and ash from biofuels. The preparation of the substance depends on the material itself. For example, coal soot can be used instantly, but the biofuel sludge must be crushed to the fineness of the cement. To improve the quality of the final product, you can mix several substances, but before that their chemical composition and additives must be investigated for environmental impact and impact on the strength characteristics of concrete ”- researcher of the Faculty of Civil Engineering and Architecture of the KTU Vytautas Bokullo.Research teams working at the Faculty of Civil Engineering and Architecture at KTU are also experimenting and developing other types of concrete mixes, such as superhard concrete, self-healing concrete, and others.

Новинка для дизайна помещений — электронные «живые» обои.

Novelty for interior design - electronic "live" wallpaper.

Dai Nippon Printing Co. (DNP), a well-known Japanese company, showed its latest development to the public - an interactive “live wallpaper” for walls, made on the basis of E-ink electronic paper. According to the developer, all these paper rolls, plasters and decorative panels “a la brick” are already past design of apartments and houses, and the future is behind living walls that can change their color and texture depending on the wishes of the owners. The developer of "live wallpaper" showed the public a wall made in the form of squares. Next to her was a mannequin in a dress of the same material. Both that, and another constantly changed the look, alternating various color combinations. Until now, the technology used in the presented interactive wallpaper has been used for the most part in creating various types of outdoor light advertising, such as billboards or scrollers. Back in 2015, the American firm E Ink Corporation, known for its monochrome displays based on electronic paper (used in electronic books and other devices), invented color decorative panels that could change their color. By refining and adapting this system, DNP has created real interactive wallpapers that can be used for interior design. But, surprisingly, the effect of the transition from one color to another was very soft and not tired eyes. In addition, such wallpaper, working on electricity, for their operation require very little energy. For example, a dress made of this material can change its color continuously for 3 days, using only one AA finger-type battery. The main difference of electronic paper from other interactive materials is its ability not to heat up in the process of work. As a result, possessing great flexibility, durability, and low energy consumption, such “live wallpapers” can get a wide range of applications.

Немецкие специалисты создали уникальный строительный материал из дерева и металла.

German experts have created a unique building material from wood and metal.

Scientists at one of the German Fraunhofer Institutes in Germany have added wood foam for an environmentally friendly insulating material with metal. The composite is lightweight, incredibly durable, and it conducts electricity. German specialists have been working with wood foam since 2014. The original foam consists of a wood powder that has been crushed to a viscosity state with the addition of gas, which gives the material an air porosity. Such panels can be made from waste wood processing industry and used for a more environmentally friendly insulation of homes than conventional foams from petroleum products. Metal-wood foam - the further development of the idea. To create it, Frauke Bunzel’s team cast a metal “sponge”, to which it added wood fiber foam. As a result of repeated mechanical immersion, viscous foam penetrates into all pores, then the material is dried. The resulting composite material provides, despite its light weight, the thermal and acoustic properties of wood foam, but with a much higher tensile strength in bending than its individual elements. In addition, the material conducts electricity. In parallel with attempts to commercialize the invention, developers are engaged in improving the production process. They hope that their product will find application in insulation panels for cars or industrial buildings
