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.

Functional Electrical Stimulation Technique May Improve Neural Implants

Researchers improve the efficiency of devices that stimulate damaged nerves, reducing potential side effects. Electrical implants that shut down excessive activity in brain cells hold great potential for treating epilepsy and chronic pain. Likewise, devices that enhance neurons’ activity may help restore function to people with nerve damage.
