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 ...

A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together.

When the separation of two surfaces approaches sub-nanometre scale, the boundary between the two most fundamental heat transfer modes, heat conduction by phonons and radiation by photons, is blurred.

There are various things we need for survival. Like water, food and energy. On the last point, our primary source of energy is the Sun, but our relationship with it can only be described as delicate.

A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the stage for more efficient energy harvesting, heat transfer and infrared ...
