What is heat conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how ...

Plasmonic device converts light into electricity

(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...

Solar-powered air-conditioning system for vehicles

Great news for drivers! They can now continue to keep the air-conditioning system on during the hot sunny days even when they stop the vehicle and switch off the engine. In collaboration with Green Power Industrial Ltd, PolyU's ...

Fur and feathers keep animals warm by scattering light

In work that has major implications for improving the performance of building insulation, scientists at the University of Namur in Belgium and the University of Hassan I in Morocco have calculated that hairs that reflect ...

Scientists transform polyethylene into a heat-conducting material

Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material ...

Insulating bricks with microscopic bubbles

The better a building is insulated, the less heat is lost in winter—and the less energy is needed to achieve a comfortable room temperature. The Swiss Federal Office of Energy (SFOE) regularly raises the requirements for ...

Paper waste used to make bricks

Researchers at the University of Jaen (Spain) have mixed waste from the paper industry with ceramic material used in the construction industry. The result is a brick that has low thermal conductivity meaning it acts as a ...

Solar panels that protect themselves in high temperatures

Smart materials are revolutionizing solar thermal collectors. A team of researchers from EPFL has developed a coating that is capable of absorbing heat as well as repelling it. Invisible to the naked eye, this process particularly ...
