Solar cell converts carbon dioxide into usable fuel
Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.The finding is reported in Science and was funded by the National Science Foundation and the U.S. Department of Energy. A provisional patent application has been filed.
Materials could alter superconductivity
Researchers, led by Carnegie's Viktor Struzhkin, have experimentally produced a class of materials blending hydrogen with sodium that could alter the superconductivity landscape and could be used for hydrogen-fuel cell storage. The research is published inNature Communications.It had been predicted that certain hydrogen-rich compounds consisting of multiple atoms of hydrogen with alkali metals like lithium, potassium or sodium, could provide a ch...
Nontoxic process makes larger sheets of 2D nanomaterials
A team of scientists led by the Department of Energy's Oak Ridge National Laboratory has developed a novel way to produce 2D nanosheets by separating bulk materials with nontoxic liquid nitrogen. The environmentally friendly process generates a 20-fold increase in surface area per sheet, which could expand the nanomaterials' commercial applications."It's actually a very simple procedure," said ORNL chemist Huiyuan Zhu, who co-authored a study pub...
Light construction innovation future-proofs wind energy systems
The giant CFRP rotor blade of a wind turbine located in front of the Messe Augsburg premises is already being touted as one of the trade fair highlights of this year. EXPERIENCE COMPOSITES – powered by JEC group is dedicating a separate showcase to the area of fibre composite applications in wind power generation.
Today’s EVs can replace 90% of vehicles on the road
It has been a very hotly debated topic in recent years. Could existing EVs, despite their limited driving range, bring about a meaningful reduction in the greenhouse-gas emissions that are causing global climate change? Researchers at MIT have just completed the most comprehensive study yet to address this question and have reached a clear conclusion: Yes, they can.
A cheaper way to produce hydrogen from water
Scientists at KTH Royal Institute of Technology in Stockholm now report that they have unlocked one major barrier to exploiting this renewable energy source. Because the best-performing catalysts for electrochemical oxidation, or "water splitting", are expensive precious metals, the research team led by KTH Professor Licheng Sun is one of many worldwide searching for cheaper alternatives. Sun had earlier developed molecular catalysts for water ox...
Germany - but not how you think
When you think of Germany, what do you think of? Most people will usually say football, beer and BMWs. What most people won't say is medical technology (medtech). Despite that, Germany’s medtech sector is by far the largest in Europe and the third largest in the world. It’s home to some of the largest OEMs and presents a wide range of opportunities for technology experts.
'Antenna-reactor' catalysts offer best of both worlds
Researchers at Rice University's Laboratory for Nanophotonics have unveiled a method for uniting light-capturing photonic nanomaterials and high-efficiency metal catalysts.Each year, chemical producers spend billions of dollars on metal catalysts, materials that spur or speed up chemical reactions. Catalysts are used to produce trillions of dollars worth of chemical products. Unfortunately, most catalysts only work at high temperatures or high pr...
Japan's 1st anti-explosive remotely operated mobile robot developed
The remotely operated 'Sakura No. 2 (anti-explosive model)' robot that features greatly reduced risk of electrical spark or heat creation that can cause explosions or fire when inflammable gas is present has been jointly developed by Mitsubishi Heavy Industries and Chiba Institute of Technology.
Sunlight and water could produce renewable hydrogen power
University of Iowa researchers are working with a California-based startup company to make clean energy from sunlight and any source of water. The university recently renewed a one-year research agreement to further develop the technology with HyperSolar, a company that aims to commercialise low-cost renewable hydrogen. Hydrogen power is arguably one of the cleanest and greenest energy sources because when it produces energy, the final byproduct ...
