How to control friction in topological insulators
16-Oct-2019
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat ...
3D-printed optics for individualized mass production
16-Oct-2019
Individually manufactured and still suitable for mass production? Within the framework of the Fraunhofer "Go Beyond 4.0" project, this apparent contradiction is to be eliminated. In the field of illumination optics, the two Fraunhofer Institutes for Silicate Research ISC and for Optics and ...
Researchers discover stable high-energy material
16-Oct-2019
High-energy materials that can store very large amounts of chemical energy and release it when required are being sought for long-haul space travel worldwide. Nitrogen compounds in which several nitrogen atoms are linked by single bonds possess this ability. These compounds are difficult to ...
Ceramic technologies for highly efficient power-to-X processes
15-Oct-2019
The speedy reduction of worldwide CO2 emissions is one of the most pressing and challenging tasks of our time. Alongside the strategy of avoiding CO2 emissions altogether, there are a number of technologies which transform unavoidable CO2 into valuable products. But these so-called power-to-X ...
An ultrafast glimpse of the photochemistry of the atmosphere
15-Oct-2019
Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols. The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between ...
Using industrial waste as insulation for buildings
15-Oct-2019
ETH spinoff FenX transforms industrial waste into a porous foam suitable for building insulation. Unlike other sustainable materials used for the purpose, this type of insulation is non-flammable and inexpensive to produce. No sooner does one of the four young men come up with the idea than they ...
New material captures carbon dioxide
The captured CO2 can be converted into useful organic materials
15-Oct-2019
A new material that can selectively capture carbon dioxide (CO2) molecules and efficiently convert them into useful organic materials has been developed by researchers at Kyoto University, along with colleagues at the University of Tokyo and Jiangsu Normal University in China. They describe the ...
CO2 for a clean performance: Rheticus research project by Evonik and Siemens enters phase 2
High-value specialty chemicals produced from CO2 and water using electricity from renewable sources and bacteria
14-Oct-2019
Evonik and Siemens launched their joint research project Rheticus II. The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals (CO2). In the Rheticus I project, the ...
Modelling the molecular architecture
New approach for the simulation of quantum chemistry
14-Oct-2019
Searching for new substances and developing new techniques in the chemical industry: tasks that are often accelerated using computer simulations of molecules or reactions. But even supercomputers quickly reach their limits. Now researchers at the Max Planck Institute of Quantum Optics in Garching ...
Sunlight degrades polystyrene faster than expected
14-Oct-2019
A study published by researchers at Woods Hole Oceanographic Institution (WHOI) shows that polystyrene, one of the world's most ubiquitous plastics, may degrade in decades or centuries when exposed to sunlight, rather than thousands of years as previously thought. "Right now, policy makers ...
