Researchers at Berkeley and Argonne National Labs discover highly promising new class of nanocatalyst
A big step in the development of next-generation fuel cells and water-alkali electrolyzers has been achieved with the discovery of a new class of bimetallic nanocatalysts that are an order of magnitude higher in activity than the target set by the U.S. Department of Energy (DOE) for 2017. The ...
Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains. The trouble with solar fuel production is the cost of producing the ...
Look out, super glue and paint thinner. Thanks to new dynamic materials developed at the University of Illinois, removable paint and self-healing plastics soon could be household products. U. of I. materials science and engineering professor Jianjun Cheng, graduate student Hanze Ying and ...
Researchers time plasmon-generated electrons moving from nanorods to graphene
Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly as well understood. Scientists at Rice are working on that, too. They suggest that the extraction of electrons ...
New molecular tools for controlling production of compounds important for flavors, human health, and biofuels
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified a new way to regulate the production of phenols, a class of plant products with a wide range of applications for humans. These compounds serve as an important source of flavors, fragrances, and ...
New findings could enhance stabilizing or destabilizing nanoparticles, depending on their uses
University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where ...
Scientists from the National Institute of Standards and Technology (NIST) and Sandia National Laboratories have added something new to a family of engineered, high-tech materials called metal-organic frameworks (MOFs): the ability to conduct electricity. This breakthrough—conductive MOFs—has ...
Fundamental discovery could speed development of efficient semiconductor-catalytic junctions
With the help of a new method called "dual-electrode photoelectrochemistry," University of Oregon scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in ...
A chemical system developed by researchers at the University of Illinois at Chicago can efficiently perform the first step in the process of creating syngas, gasoline and other energy-rich products out of carbon dioxide. A novel "co-catalyst" system using inexpensive, easy to fabricate ...
Gold-palladium nanocatalysts set new mark for breakdown of nitrites
Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers. Nitrites and their more abundant cousins, nitrates, are inorganic compounds ...
