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 ...

Wood-derived foam materials

Since most foam materials are made of petrochemical plastics, they aren't very climate-friendly. But now an alternative is in sight – a novel foam material produced entirely from wood, which is not harmful to the environment ...

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 ...

Solving a mystery of thermoelectrics

Materials that can be used for thermoelectric devices—those that turn a temperature difference into an electric voltage—have been known for decades. But until now there has been no good explanation for why just a few ...

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 ...
