Aluminum to Replace Copper as Conductor in On-board Power Systems

Electric power and electronics play an increasing role in vehicles. Currently copper is the conductive material of choice but in comparison to aluminum, it is heavy and expensive. Before aluminum can replace copper in power supply systems, a number of technological challenges need to be surmounted.

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.
