A Single Atom Structure Offers a More Efficient Catalyst
January 31, 2019 | Leave a Comment
A Virginia Tech discovery shows an efficiency rate that is up to 25 times higher than traditional catalysts made from larger iridium structures or nanoparticles. Catalysts are materials widely used in industry to speed reactions for making gasoline, pharmaceutical drugs, and for cleaning up car exhaust. They typically contain expensive precious metals, which can make […]

Energy Efficient Transistors Save Energy
January 30, 2019 | Leave a Comment
University of Erlangen-Nuremberg researcher’s new method finds defects in power transistors more accurately, quickly and simply. Transistors are needed wherever current flows, and they are an indispensable component of virtually all electronic switches. In the field of power electronics, transistors are used to switch large currents. However, one side-effect is that the components heat up […]

Making Ammonia Without Using Natural Gas
January 29, 2019 | Leave a Comment
Case Western Reserve University researchers have come up with a new way to create ammonia from nitrogen and water at low temperature and low pressure. They’ve done it successfully so far in a laboratory without using hydrogen or the solid metal catalyst necessary in traditional processes. Ammonia, a compound first synthesized about a century ago, […]

New Model For Better Well Fracking
January 24, 2019 | 2 Comments
Los Alamos National Lab’s new computational model could potentially boost efficiencies and profits in natural gas production by better predicting previously hidden fracture mechanics. It also accurately accounts for the known amounts of gas released during the process. Zdeněk Bažant, McCormick Institute Professor and Walter P. Murphy Professor of Civil and Environmental Engineering, Mechanical Engineering, […]

New Materials Improve Performance of Perovskite Solar Cells
January 23, 2019 | Leave a Comment
Universities of Portsmouth, Southampton and Bath researchers have now developed a way to adjust the properties of the transport layers to encourage the ionic defects within the perovskite to move in such a way that they suppress recombination and lead to more efficient charge extraction – increasing the proportion of the light energy falling on […]
