Improving batteries' energy storage

MIT researchers have found a way to improve the energy density of a type of battery known as lithium-air (or lithium-oxygen) batteries, producing a device that could potentially pack several times more energy per pound than ...

3D graphene: Solar cells' new platinum?

One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.

Future looks bright for carbon nanotube solar cells

(Phys.org) —In an approach that could challenge silicon as the predominant photovoltaic cell material, University of Wisconsin-Madison materials engineers have developed an inexpensive solar cell that exploits carbon nanotubes ...

New battery design could help solar and wind power the grid

(Phys.org) —Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become ...

A hot bath for gold nanoparticles

Gold nanoparticles, says Chris Kiely, are fast becoming some of the most effective diplomats of the nanoworld.

A material that most liquids won't wet

(Phys.org)—A nanoscale coating that's at least 95 percent air repels the broadest range of liquids of any material in its class, causing them to bounce off the treated surface, according to the University of Michigan engineering ...
