Converting Heat Waste to Electricity Closer To Reality

Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past.

Graphene is the new electronic material  for high-performance devices

That material, the focus of the 2010 Nobel Prize in physics, is graphene – a fancy name for extremely thin layers of ordinary carbon atoms arranged in a “chicken-wire” lattice. These layers, sometimes just a single atom thick, conduct electricity with virtually no resistance, very little heat generation – and less power consumption than silicon.

The World’s Smallest Battery

A benchtop version of the world’s smallest battery — its anode a single nanowire one seven-thousandth the thickness of a human hair — has been created by a team led by Sandia National Laboratories researcher Jianyu Huang.
