Controlling thermal conductivity of polymers with light

Polymers are regularly used as thermal insulators for everything from keeping beverages hot to keeping sensitive electronics cool. In some cases, polymers can even be used as thermal conductors to enable efficient heating ...

Very thin film could help manage heat flow in future devices

Purdue University researchers have demonstrated the ability of a thin film to conduct heat on just its surfaces, identifying a potential solution to overheating in electronic devices such as phones and computers.

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 ...

Heating apartment houses sustainably

For the energy transition to be successful, it will also be important to secure heat supply of the housing stock by sustainable technologies. About half of the apartments in Germany is located in apartment buildings. However, ...

Door manufacturer benefits from simulation tools

Building burglary-resistent doors with thermal insulation is a challenge for manufacturers. Their complex structure provides holes for the flow of air. With scientific simulation methods, Fraunhofer researchers have designed ...

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 ...
