  • New ultra-thin film for interference-free 5G and 6G

    New ultra-thin film for interference-free 5G and 6G

    With the new film made from a special composite material, KIMS is demonstrating how electromagnetic interference in communication systems can be effectively minimised. The film, which is only 0.5 mm thick, absorbs more than 99% of electromagnetic waves in frequency ranges such as 5G, 6G and WiFi. This shielding technology avoids disruptive reflections and offers unrivalled freedom from interference. An advantage that could further optimise the use of modern communication devices and radar systems.

    Absorption instead of reflection
    Conventional shielding materials often rely on reflection, but this is only partially effective. The new type of film, on the other hand, absorbs electromagnetic waves in a targeted manner and thus ensures a high level of interference immunity. This approach prevents waves from bouncing back and interfering with neighbouring systems. The technology is based on a unique crystal structure and a magnetic composite layer that precisely filters frequencies and ensures maximum absorption.

    Flexible and dimensionally stable for a wide range of applications
    The developed film shows high flexibility and dimensional stability, even after thousands of folds. These properties make it ideal for flexible and portable devices such as smartphones and electronics. It also offers reliable shielding and high durability for roll-up screens and other flexible technologies. The film remains dimensionally stable and functional even in demanding applications. Ideal for use in modern, portable devices.

    Optimisation through carbon nanotubes
    A thin carbon nanotube film on the back of the film further increases the shielding performance. With an absorption coefficient of 99.9%, the film ensures that electromagnetic waves do not penetrate to the outside and that interference in various mobile and autonomous applications is minimised. This innovative combination of materials creates reliable shielding, which is particularly in demand in areas with high sensitivity to electromagnetic interference.

    With its high absorption and flexibility, the new KIMS film offers an ideal solution for minimising interference in modern communication technology. It enables better freedom from interference in 5G and 6G networks and could bring ground-breaking improvements in autonomous systems and portable devices – a promising development for future digital infrastructure.

  • Revolutionary building monitoring

    Revolutionary building monitoring

    Monitoring the statics and stability of structures requires maximum precision. This is precisely where the innovative metamaterial from the Karlsruhe Institute of Technology (KIT) comes in. This metamaterial, with artificially produced structures, exhibits exceptional elongation properties that conventional materials do not offer. Developed by a research team led by Professor Martin Wegener, the material can “communicate” forces and deformations over large distances, which was previously considered unthinkable in structural monitoring.

    Overcoming local limitations
    Metamaterials were previously limited to local interactions. The new material from KIT, however, enables the building blocks to interact with each other over long distances. Dr Yi Chen from KIT compares this property to “direct communication” within the material. A development that could revolutionise materials research and structural monitoring. This new type of structure opens up the possibility of monitoring buildings over a large area and reacting to structural changes at an early stage.

    Unusual elongation properties for greater safety
    One remarkable feature of this metamaterial is its reaction to elongation. It exhibits uneven expansion and compression in different sections. Unlike materials such as rubber, compression even occurs in some areas, which can indicate specific loads. These high sensitivity properties of the material make it ideal for engineering teams to closely monitor critical areas of a structure and react proactively to changes.

    More than construction monitoring
    The high sensitivity of the metamaterial opens up new possibilities not only in the construction industry, but also in biotechnology. The ability to precisely measure forces over large areas could also be used to characterise cell forces or for biological applications. The development therefore not only advances structural monitoring, but also offers new approaches in biological research.

  • The future of wireless communication

    The future of wireless communication

    Kirigami, an ancient Japanese art form of cutting and folding paper, is now inspiring modern scientists to create ground-breaking solutions in the field of communications technology. Researchers at the University of British Columbia and Drexel University have further developed this technique to create flexible and powerful antennas that can be easily adapted to different conditions. These flexible structures could fundamentally change the way wireless communication works.

    MXene nanomaterials
    MXene materials, a relatively new class of two-dimensional materials, are at the centre of this technological revolution. They are characterised by high conductivity and are therefore ideal for use in communication systems. In combination with the Kirigami technique, MXene is printed onto flexible substrates, creating complex 3D structures that act as antennas. These antennas can adjust their frequency through mechanical changes such as tension or compression, making them particularly versatile.

    Versatile applications in modern technology
    The ability to reconfigure antennas easily and cost-effectively opens up a wide range of applications. Especially in aerospace and robotics, these flexible antennas could offer enormous advantages. The ability to adapt to changing requirements makes them ideal for use in systems that are in motion or in changing environments. From satellites to autonomous robots – the potential applications are diverse and exciting.

    Efficient production for complex structures
    Despite the highly developed technology, the production of these antennas is remarkably simple. Using an acetate film and conductive MXene ink, the Kirigami technique can be used to create three-dimensional structures that protrude from a flat surface. These structures can be easily customised to vary the transmission frequency, eliminating the need for complex control systems.

    The combination of Kirigami and MXene nanomaterials could lead wireless communication into a new era. For property and site development professionals, this technology offers exciting new opportunities to make smart buildings and connected infrastructures even more efficient and sustainable. Flexibility, efficiency and innovative strength make this development a pioneering step in telecommunications technology.

  • Erster echter Null-Emissions-Ersatz für Portlandzement

    Erster echter Null-Emissions-Ersatz für Portlandzement

    Die Herstellung von Zement ist für rund sieben Prozent der globalen CO2-Emissionen verantwortlich, vor allem aufgrund der energieintensiven Hochtemperaturprozesse und der Verwendung von Kalkstein. Ein neues Verfahren könnte diesen Prozess revolutionieren. Das Startup Sublime Systems hat einen CO2-neutralen Zement entwickelt, der auf elektrochemische Prozesse setzt. Inspiriert von den Techniken der Römer, die ohne extreme Hitze stabile Bauwerke schufen, kombiniert Sublime Systems altes Wissen mit modernster Technologie.

    Bauprojekte mit nachhaltigem Zement
    Sublime Systems hat bereits einen wichtigen Meilenstein erreicht. In Bostons grösstem klimaneutralen Bürogebäude wurden drei Tonnen des neuartigen Zements verbaut. Die erste kommerzielle Produktionsanlage des Unternehmens in Holyoke, Massachusetts, soll 2026 in Betrieb genommen werden und eine Kapazität von 30.000 Tonnen pro Jahr haben. Diese Anlage dient als Modell für die Skalierung der Technologie, mit dem Ziel, zukünftig Fabriken mit einer Jahreskapazität von Millionen Tonnen weltweit zu errichten.

    Elektrochemie statt Hochtemperaturverfahren
    Die Idee für Sublime Systems entstand im Labor von Professor Chiang am MIT. Leah Ellis und Andres Blades untersuchten die chemischen Prozesse der Zementherstellung und entwickelten daraufhin ein Verfahren, das auf Elektrizität statt auf Hitze setzt. Die innovative Technologie umgeht die CO2-intensiven Schritte der herkömmlichen Zementproduktion und bietet eine echte Null-Emissions-Lösung.

    Zukunft der Zementproduktion
    Sublime Systems sieht sich als Vorreiter einer klimafreundlichen Zementproduktion. Mit der neuen Methode zeigt das Unternehmen, dass nachhaltige Alternativen möglich sind, ohne die Leistungsfähigkeit des Materials zu beeinträchtigen. Durch die Partnerschaften mit Immobilienunternehmen wie WS Development wird der Zement bereits in realen Bauprojekten eingesetzt, was das Potenzial der Technologie unter Beweis stellt.

  • Planned skyscraper to be 190 metres high

    Planned skyscraper to be 190 metres high

    Just a few decades ago, it was unthinkable that timber buildings could be more than a few storeys high. But in recent years, advances in timber construction have opened up new possibilities. In Milwaukee, a ground-breaking project is on the horizon. A 190 metre high wooden skyscraper is to be built, setting a new world record in timber construction. The renowned architectural firm Michael Green Architects (MGA) from Vancouver has developed the plans for this visionary building, which is intended to impress not only with its height but also with its sustainable construction method.

    Highly technologised solid wood
    The wood used to build the skyscraper is much more than conventional timber. Glulam and cross-laminated timber, two main components of the project, consist of several glued layers of wood that offer exceptional strength and resistance. These materials can withstand moisture and extreme weather conditions and are also fireproof. In the event of fire, solid wood forms a protective carbon layer that stabilises the structure and prevents collapse.

    Another advantage of solid wood is its environmental friendliness. As it grows, wood absorbs CO₂ and stores it. This property makes wood a climate-friendly building material that helps to significantly reduce the carbon footprint of a construction project. The use of prefabricated timber modules also speeds up the construction process, saving time and money.

    A building that sets standards
    The planned timber skyscraper in Milwaukee will not only be a record-breaking building, but also a symbol of the future of construction. In addition to the innovative timber construction method, the building will create a multifunctional centre comprising 750 residential units, 190,000 square metres of office space, 40,000 square metres of retail space and 300 hotel rooms. It is being built in the heart of the city, right next to the Marcus Performing Arts Centre, and is part of a comprehensive urban development initiative.

    The project is also one of the largest and most ambitious in economic terms that Milwaukee has ever seen. With an investment of over 700 million dollars, it will have a lasting impact on the city’s skyline and create new jobs.

    Challenges and potential
    Despite the many advantages, the project will not be realised without challenges. Wood alone is not enough to fulfil all the structural requirements for a building of this height. It is likely that steel and concrete will be needed for reinforcement, similar to other projects of this size. Nevertheless, the project shows that timber in combination with other materials is a serious alternative in building construction.

    A look at other projects illustrates the potential. In Switzerland, the 100 metre high “Rocket” is currently being planned in Winterthur, which is set to become the world’s tallest purely timber skyscraper. In contrast to the planned skyscraper in Milwaukee, the Rocket will use only wood, without any additional reinforcement in the form of steel or concrete. This shows that the use of wood as a load-bearing material in building construction is becoming increasingly important worldwide.

    Future prospects for high-rise construction
    The timber skyscraper in Milwaukee is being built in several phases in order to optimise the structure and meet the high safety requirements. The architects are using state-of-the-art techniques and materials to design the building efficiently and sustainably. The building is not only intended to set new standards for timber construction, but also to be a model for the future development of high-rise buildings worldwide.

    The combination of sustainability and technological progress makes the planned timber skyscraper a milestone in the construction industry and a symbol of the architectural possibilities of the 21st century.

  • Green hydrogen: Study identifies Canada as a top location

    Green hydrogen: Study identifies Canada as a top location

    Researchers at the Paul Scherrer Institute(PSI) have focussed on the question of where hydrogen can be produced efficiently and cost-effectively with the aim of stopping climate change and emitting no more greenhouse gases in the future. According to a press release, the researchers have compiled geographical and economic data and forecasts to describe the development of a hydrogen economy. To do so, they analysed four scenarios with a hydrogen demand of between 111 and 614 megatonnes per year. The study can currently be read in the scientific journal “Nature Communications“.

    There are various technologies for producing hydrogen. In polymer electrolyte membrane electrolysis (PEM), hydrogen is extracted from water in an electrolyser. The great advantage of this process is that the energy for the conversion can be obtained from green electricity. The question to be resolved is where the high demand for green electricity can best be met.

    “We primarily applied economic criteria,” says Tom Terlouw, PhD student at PSI and lead author of the study, quoted in the press release. “In other words, where is production most favourable?” Two focal points crystallised: Where is there enough wind or sun to cover the enormous demand for green electricity? And where is there enough free space to set up the plants required for production? Canada proved to be ideal here. “There are many open areas there that are very windy and therefore ideal for setting up wind turbines,” adds Terlouw. The central USA, parts of Australia, the Sahara, northern China and north-west Europe are also ideal locations. Central European countries such as Switzerland, on the other hand, are less suitable as there is neither open space nor sufficient sunlight. The researchers also point out that the production of green hydrogen still generates residual greenhouse gas emissions from the production and transport of the required materials. In order to compensate for these residual emissions, corresponding quantities of carbon dioxide would have to be filtered out of the atmosphere, according to the study.

  • No complex thinking skills with ChatGPT & Co.

    No complex thinking skills with ChatGPT & Co.

    The research, which will be presented at the annual meeting of the Association for Computational Linguistics in Bangkok, concludes that large language models such as ChatGPT show no evidence of the development of sophisticated or planned thinking. Instead, these models only demonstrate the ability to respond to simple instructions. This disproves the widespread assumption that AI models could exhibit increasingly intelligent behaviour through scaling.

    Background to the study
    The study, led by Prof Dr Iryna Gurevych from TU Darmstadt and Dr Harish Tayyar Madabushi from the University of Bath, investigated so-called “emergent capabilities” of AI models. These capabilities, which were observed with increasing model size and data volume, raised both hopes and fears regarding the future development of artificial intelligence. However, current research shows that these abilities are due to simple learning effects rather than complex, independent thinking.

    Implications for the future of AI use
    The results of the study have significant implications for the use of AI systems. Prof Gurevych warns against relying on the models to solve complex tasks without human support. She emphasises that users should provide explicit instructions and examples in order to use the systems effectively. In addition, the tendency of models to produce plausible-sounding but incorrect results remains a challenge.

    Focus on future risks
    Although the study shows that LLMs do not develop complex thinking skills, this does not mean that AI does not pose a threat. Prof Gurevych calls for research to focus on the real risks of AI models, particularly their potential to generate fake news. The findings of the study provide a valuable basis for better understanding the actual capabilities of AI models and making their use safer in practice.

  • Largest 3D-printed housing estate being built in Texas

    Largest 3D-printed housing estate being built in Texas

    In the Wolf Ranch community in Georgetown, Texas, 100 single-storey houses are being built using the Vulcan printer from ICON. This 3D printer builds the houses layer by layer from a special concrete mix that is robust and weather-resistant. The construction process saves time and labour while creating walls that can withstand extreme weather conditions.

    Resilience and modern challenges
    The solid concrete walls of the houses not only offer excellent protection against extreme weather conditions, but also provide excellent insulation. This construction proves particularly useful in hot summer months, as the interiors remain cool and the air conditioning systems are relieved. However, the thick walls also pose challenges: the signal strength of wireless networks is impaired, which is why many residents rely on meshed routers.

    Building revolution
    The Wolf Ranch homes, known as the “Genesis Collection”, are available for between 450,000 and 600,000 dollars, and a quarter of the units have already been sold. The project demonstrates the potential of 3D printing to change the construction industry for good. ICON already built its first 3D-printed house in Austin in 2018 and is even planning to use the technology on the moon as part of NASA’s Artemis programme in the future.

    3D printing on the upswing worldwide
    3D printing in the construction industry is also picking up speed in Germany. the first 3D-printed detached house was opened in Beckum in 2021, and further projects, such as the publicly subsidised apartment block in Lünen, are in the pipeline. These developments show that 3D printing is becoming increasingly important worldwide and will potentially shape the future of construction.

  • A cost-effective alternative to conventional power plants

    A cost-effective alternative to conventional power plants

    According to the Fraunhofer ISE study, ground-mounted PV systems and onshore wind turbines are currently the most cost-effective technologies for generating electricity in Germany. The electricity generation costs for these systems are between 4.1 and 9.2 cents per kilowatt hour, undercutting not only other renewable energies but also all conventional power plant types.

    Battery storage as a valuable addition
    Photovoltaic battery systems have electricity production costs that vary between 6.0 and 22.5 cents per kilowatt hour, depending on the location and battery system. This shows the enormous potential of this technology, especially in combination with ground-mounted PV systems and wind farms. Dr Christoph Kost from Fraunhofer ISE emphasises the advantages of such combinations: “The combination allows grid capacities to be better utilised.”

    Cost reductions expected by 2045
    The study also provides a forecast for cost developments up to 2045. Small rooftop PV systems could then supply electricity for 4.9 to 10.4 cents per kilowatt hour, while ground-mounted PV systems could reach 3.1 to 5.0 cents per kilowatt hour. Significant cost reductions to between 7 and 19 cents per kilowatt hour are also expected for small PV battery systems, provided that storage prices fall as forecast.

    Flexible power plants remain necessary
    Despite the positive developments in renewable energies, flexibly controllable power plants remain indispensable as a back-up. Biogas and biomass power plants could take on this role to some extent, but at significantly higher costs. For example, the electricity generation costs for biogas are between 20.2 and 32.5 cents per kilowatt hour and for biomass plants between 11.5 and 23.5 cents per kilowatt hour.

    Hydrogen power plants as a supplement
    The study also shows the costs for hydrogen-fuelled gas and steam turbine power plants in 2030: they amount to between 23.6 and 43.3 cents per kilowatt hour. These costs result from the high expenses for CO2 and hydrogen procurement. Paul Müller from Fraunhofer ISE emphasises the necessity of these technologies as a supplement: “We need them as an important addition. However, their operation will be limited to the bare minimum.”

    The results of the Fraunhofer study make it clear that photovoltaic systems with battery storage are not only a cost-efficient alternative to conventional power plants, but also a future-proof one. The expected cost reductions by 2045 make renewable energies an increasingly attractive option for power generation.

  • Canadian researchers discover super-black wood

    Canadian researchers discover super-black wood

    A team led by Professor Philip Evans and doctoral student Kenny Cheng from the University of British Columbia made an astonishing discovery during an experiment to produce water-repellent wood: super-black wood. This material absorbs almost all of the light that strikes it, significantly outperforming the light absorption of normal black paint.

    “Ultra-black or super-black material can absorb more than 99 percent of the light that hits it – significantly more than normal black paint, which absorbs about 97.5 percent of the light,” explains Professor Evans. In collaboration with Texas A&M University, they confirmed that the new material, which they named Nxylon, reflects less than one percent of visible light.

    The properties of Nxylon
    Nxylon, named after the Greek goddess of the night Nyx and the Greek word for wood, Xylon, is made from North American linden wood and can also be made from European linden wood. The material does not require pigments to create its deep black color, but uses its unique structure to capture light and prevent reflections. This property makes it an ideal candidate for various applications that require high light absorption.

    Potential applications in various industries
    The exceptional ability to absorb light opens up numerous application possibilities. Nxylon could increase the efficiency of solar cells by absorbing more sunlight. In astronomy, super-black materials could improve image sharpness by minimizing scattered light. The discovery offers a sustainable and luxurious alternative to expensive and rare black woods such as ebony. It could also serve as a substitute for the black gemstone onyx in jewelry.

    Commercialization and future plans
    Dr. Evans and his team plan to establish a start-up company, Nxylon Corporation of Canada, to commercialize the material. They would like to work with jewelers, artists and designers to develop various products. There are also plans to build a commercial plasma reactor to produce larger quantities of the material.

    “Nxylon can be made from sustainable and renewable materials that are widely available in North America and Europe, leading to new applications for wood. The wood industry in British Columbia is often seen as a declining industry that focuses on standard products – our research shows its great untapped potential,” emphasizes Dr. Evans.

    The discovery could therefore not only revolutionize the solar energy and luxury goods industries, but also provide new impetus for the wood industry.

  • Aerogel Architecture Award 2024 honors innovative projects

    Aerogel Architecture Award 2024 honors innovative projects

    This year’s “Aerogel Architecture Award” was looking for projects that demonstrate the potential of the high-performance insulating material aerogel in architecture and construction. The “Stringi-Stringi” renovation project from Livorno, Italy, came out on top in the “Realized Projects” category. The project, supervised by the architecture firm SB Ingegneria, optimized a poorly insulated building from 1939 by implementing five decisive measures: Roof insulation, façade renovation, conversion of the heating system to a heat pump, installation of a photovoltaic system and replacement of the windows with aerogel seals. The flexible use of aerogel made it possible to upgrade the energy efficiency of the façade without altering the historic appearance.

    Innovative renovation concepts
    Second place went to the Eversbuschstrasse kindergarten in Munich, whose 120-year-old building was converted into an integrated kindergarten using simple means and aerogel materials. The project focused on the reuse of existing structures and materials, with aerogel offering maximum thermal insulation and design freedom. Third place went to the Andreas Schubert building at the Technical University of Dresden. The listed building was fitted with 50 mm thick aerogel insulation and optimized for energy efficiency while retaining its characteristic façade.

    Visionary student projects
    In the “Student Projects” category, the Brazilian duo Amanda Sayuri Hashimoto and Guilherme Pinheiro e Silva won with their “Tassi Museum” project. They are planning to renovate the “Hotel Tassi” in Curitiba, which was damaged by fire, and turn it into a museum. Aerogel insulation on the façade and a roofing of the inner courtyard made of aerogel layers within glass panes improve energy efficiency without affecting the historical substance.

    Creative approaches to social architecture
    Patricia Malota from Poland took second place with her design for an urban mental health center in Krakow. Her concept uses translucent aerogel façades to create a bright, inviting atmosphere. Third place went to Michael Chang and Adrian Corbey from Harvard University with their “Aeroblock” project. They proposed a contemporary insulation for the glass façade of the Carpenter Center for Visual Arts without compromising the iconic look of the building.

    Further information on all submitted projects is available on the Empa website.

  • Recycled cement is best suited for CO2 mineralization

    Recycled cement is best suited for CO2 mineralization

    Cement recycling is a cheap and efficient way to reduce emissions if the cement is permanently mineralized with emitted and atmospheric CO2. Of the ten technologies examined in a study, the one that uses recycled cement paste from demolished concrete from infrastructure and buildings is the most effective and economical. It has the potential to reduce emissions from cement production by around 15 percent. This would have corresponded to a total of 0.8 percent of global greenhouse gas emissions in 2020.

    This is the conclusion of a study led by researchers from Imperial College London, in which scientists from the Swiss Federal Laboratories for Materials Science and Technology(Empa) and the Swiss Federal Institute of Technology Lausanne(EPFL) are also involved.

    According to a report by Empa, building materials are responsible for around 13 percent of global greenhouse gas emissions. Most of this comes from the production of concrete and steel. “Our findings suggest that CO2-mineralized cement could be a leading technology to help us decarbonize the sector,” lead author Rupert J. Myers is quoted as saying in the report.

    According to co-author Ellina Bernard from the Empa Laboratory for Concrete and Asphalt, a broader application of CO2 mineralization using old concrete or other calcium-based industrial waste is limited by the amount of material to be carbonated. “However, CO2 savings of 15 percent in the production of building materials are not negligible.” Further work must now be done to optimize CO2 capture and recycling technologies and to reduce costs.
