New thermocell could harvest 'waste heat'

(Phys.org) —Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.

Scientists create artificial mini 'black hole'

(PhysOrg.com) -- Scientists from China have built a device that can trap and absorb microwaves coming from all directions with a 99% absorption rate - a property that makes the device simulate, to some extent, an astrophysical ...

The sun is a star when it comes to sustainable energy

At a national scientific meeting last week where biofuels - principally ethanol - were uniformly trashed as an environmental train wreck, one bright, carbon-free light gleamed in our energy future: the sun.

Breaking the Planck's law, at the nanoscale

(PhysOrg.com) -- A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists ...

NASA to map the surface of an asteroid

NASA's OSIRIS-REx spacecraft will launch September 2016 and travel to a near-Earth asteroid known as Bennu to harvest a sample of surface material and return it to Earth for study. The science team will be looking for something ...

A new law for metamaterials

Metamaterials, which are engineered to have properties not found in nature, have long been developed and studied because of their unique features and exciting applications. However, the physics behind their thermal emission ...
