Innovative textile vents to release heat when you sweat

Materials Scientists at Duke University have developed a lightweight material that traps thermal energy when dry, but opens a series of tiny vents to let heat escape when a person starts sweating. The vents close again to ...

Understanding phase change materials for thermal energy storage

As the world searches for practical ways to decarbonize our activities and mitigate associated climate change, approaches to alternative energy are hampered by the intermittent nature of energy sources, such as solar and ...

Some polycrystal grain boundaries feel the heat more than others

Polycrystals are solid materials that are made up of lots of small crystals. The points where the crystals meet are known as grain boundaries (GBs). GBs are important because they can affect the way the solid behaves. However, ...

Three-channel Kondo effect discovered in cubic holmium compound

A scientist from Tokyo Metropolitan University has applied numerical methods to capture the hallmarks of a quantum phenomenon known as the three-channel Kondo effect in an f-electron system for the first time. Professor Takashi ...

When vibrations increase on cooling: Anti-freezing observed

An international team has observed an amazing phenomenon in a nickel oxide material during cooling: Instead of freezing, certain fluctuations actually increase as the temperature drops. Nickel oxide is a model system that ...

Filming the thermal death of electrons in matter

It is well known that an electric current increases the temperature of the material through which it is conducted due to the so-called Joule effect. This effect, which is used daily in domestic and industrial heaters, hair ...
