Technique Boosts High-Power Potential For Gallium Nitride Electronics

Gallium nitride (GaN) material holds promise for emerging high-power devices that are more energy efficient than existing technologies – but these GaN devices traditionally break down when exposed to high voltages. Now researchers at North Carolina State University have solved the problem, introducing a buffer that allows the GaN devices to handle 10 times greater power.

Looking to Cow Rumen for Better Biofuels Enzymes

A cow's digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen – the cow's primary grass-digestion chamber – that contribute to the breakdown of switchgrass, a renewable biofuel energy source.

Fuel Cell Research and Development Funding Opportunity

Fuel cells use the chemical energy of hydrogen or other fuels to efficiently produce electricity or heat with minimal byproducts, primarily water. The DOE is accepting applications for a total of up to $74 million to support the research and development of clean, reliable fuel cells for stationary and transportation applications.

Solar Reactor Converts Carbon Dioxide and Water Into Fuel

Cerium oxide — or ceria — is a common metal most famously used in self-cleaning ovens, and it is the centerpiece of a new technology from California Institute of Technology that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels.

High-Resolution Wind Measurements for Offshore Wind Energy Development

A mathematical transform, called the Rosette Transform, together with a new method, called the Dense Sampling Method, have been developed. The Rosette Transform is invented to apply to both the mean part and the fluctuating part of a targeted radar signature using the Dense Sampling Method to construct the data in a high-resolution grid at 1-km posting for wind measurements over water surfaces such as oceans or lakes.
