A step forward in making hydrogen-powered cars
A radical process that allows hydrogen to be efficiently sourced from liquid formic acid could be one step forward in the making of hydrogen-powered cars.Using formic acid to produce hydrogen has never been considered viable because it requires high temperatures to decompose and also produces waste by-products.But the University of Melbourne's Professor Richard O'Hair has led an international team of scientists in designing a molecular catalyst t...
Stored renewable energy can be efficiently interconverted
Researchers at PNNL have demonstrated that stored renewable energy can be interconverted efficiently and inexpensively by mimicking enzymatic catalysts used in biological processes. Enzymes consist of an active site-a metal where the reaction happens with connections to the rest of the protein-and a protein scaffold surrounding the active site. That PNNL research team, led by Dr. Wendy Shaw, predicted that many parts of the protein scaffold play ...
The importance of driving conditions for moving nanocars
Rice University researchers who developed the first nanocars and colleagues at North Carolina State University found in recent tests that driving their vehicles in ambient conditions – exposed to open air, rather than a vacuum – got dicey after a time because the hydrophobic single-molecule cars stuck to the "road" and created what amounted to large speed bumps.The findings were reported in the American Chemical Society's Journal of P...
Solar module exposure to the elements
Intense sunlight, searing heat and high exposure to dust; solar modules in the desert are exposed to different climate conditions than those in Germany. An interesting challenge for the solar researchers at the Fraunhofer CSP in Halle. Author: Kathrain Graubaum (text and photo)
Technology enables clean and safe chemical production
A technology called HydRegen is being developed by Professor Kylie Vincent and her team in the Department of Chemistry at the University of Oxford that promises to make the production of fine chemicals 'cheaper, faster, safer and cleaner'.The project was recently awarded an Innovate UK/EPSRC grant worth £2.9 million and was the overall winner of the Royal Society of Chemistry's Emerging Technology competition in 2013.
Catalyst allows easy conversion of natural gas into fuel
ETH scientists have discovered a catalyst that allows the easy conversion of natural gas constituents into precursors for the production of fuels or complex chemicals, such as polymers or pharmaceuticals. The new catalyst is extremely stable and results in fewer unwanted by-products.The use of natural gas as a raw material for chemicals production is a goal pursued intensively in chemical research.
LEDs for industrial and outdoor applications
The recently released RLE EXC OTD 2x4/ 2x8 HP LED modules from Tridonic are resistant to overvoltage and are geared towards demanding outdoor and industrial applications. They can be combined with standard lenses and support modular luminaire design. Thanks to a variety of beam characteristics many different lighting scenarios can be created.
Electrode catalysts for Honda’s Clarity Fuel Cell vehicle
The Clarity Fuel Cell vehicle from Honda, which went on sale in March, is using platinum electrode catalysts from Tanaka Holdings in its fuel cells.
Electronic material restores functions after it breaks
Electronic materials have been a major stumbling block for the advance of flexible electronics because existing materials do not function well after breaking and healing. A new electronic material created by an international team, however, can heal all its functions automatically even after breaking multiple times. This material could improve the durability of wearable electronics.
Proton-conducting material found in electrosensory organs of sharks
Sharks, skates, and rays can detect very weak electric fields produced by prey and other animals using an array of unusual organs known as the ampullae of Lorenzini. Exactly how these electrosensory organs work has remained a mystery, but a new study has revealed an important clue that may have implications for other fields of research.
