Heat energy can flow by conduction, convection or radiation. It always flows from a region of high temperature to a region of low temperature i.e. from hot to cold. Conduction is the flow of heat ...

Radiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation. Unlike conduction and convection, radiation takes place without the ...

Scientists develop a revolutionary thermal emitter with 60% efficiency, paving the way for scalable and sustainable energy ...

Radiative heat transfer is one of the most critical energy transfer mechanisms in nature. However, traditional blackbody radiation, due to its inherent characteristics, such as its non-directional, ...

and how their properties change when they are exposed to extreme heat and lots of particle radiation. As they get irradiated, ...

Global warming and extreme heat events are having an increasing impact on human health. In corresponding studies, the ambient ...

New experiments by swiss researchers have show that industrial-relevant temperatures of 1,050°C can be generated from solar ...
