Solar Nanowire Template Permits Flexible Energy Absorption

Researchers creating electricity through photovoltaics want to convert as many of the sun’s wavelengths as possible to achieve maximum efficiency. For this reason, they see indium gallium nitride as a valuable future material for photovoltaic systems. Changing the concentration of indium allows researchers to tune the material’s response so it collects solar energy from a variety of wavelengths.

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries

Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.

A Better Understanding of High-Temperature Superconductors

Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, super-efficient motors and generators, and myriad other schemes. But such everyday applications still lie in the future, because conventional superconductivity in metals can’t do the job.
