Researchers have taken a key step toward helping wildlife coexist more safely with wind power generation by demonstrating the success of an impact detection system that uses vibration sensors mounted to turbine blades.
It defies conventional wisdom about semiconductors. It's baffling that it even works. It eludes physics models that try to explain it. This newly tested class of light-emitting semiconductors is so easy to produce from solution that it could be painted onto surfaces to light up our future in myriad colors shining from affordable lasers, LEDs, and even window glass.
MIT, Harvard, and LBNL physicists have discovered a new quantum electronic material, the 'kagome metal,' whose atomic structure resembles a Japanese basketweaving pattern and exhibits exotic, quantum behavior.
A research team from Tokyo Institute of Technology (Tokyo Tech) and Waseda University have successfully produced high-quality thin film monocrystalline silicon with a reduced crystal defect density down to the silicon wafer level at a growth rate that is more than 10 times higher than before. In principle, this method can improve the raw material yield to nearly 100 percent.
Chemical Engineers at EPFL have developed a new method for making meta-organic framework membranes that can be used to considerably improve energy-expensive processes such as propylene-propane separation, which accounts for 40 percent of energy used in the global petrochemical industry.
One of the key ways to combat global climate change is to boost the world's use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.
Zero-emissions cars zipping into a sustainable energy future are just one dream powered by fuel cells. But cell technology has been a little sluggish and fuel prohibitively pricey. This new catalyst could offer a game changer. And there are more developments to come.
Trung Van Nguyen has headed research that today verges on development of a commercial hydrogen-bromine flow battery, an advanced industrial-scale battery design engineers have strived to develop since the 1960s.
Lithium and cobalt are fundamental components of present lithium-ion batteries. Analysis by researchers at the Helmholtz Institute Ulm (HIU) of the Karlsruhe Institute of Technology (KIT) shows that the availability of both elements could become seriously critical. Cobalt-free battery technologies, including post-lithium technologies based on non-critical elements such as sodium, but also magnesium, zinc, calcium and aluminum, represent possibilities to avoid this criticality in the long term. These results are presented in Nature Reviews Materials.
Mixed-plastic electronics waste could be a valuable source of reusable polymers, a new study led by Illinois Sustainability Technology Center scientists suggests. The team has developed the first energy-efficient and environmentally friendly process that separates mixed polymers so that they can be recycled into new, high-quality plastic products.
