The old saw that a watched pot never boils may not apply to pots given an ultra-thin layer of aluminum oxide, which researchers have reported can double the heat transfer from a hot surface to a ...

Water can exist in three phases: a frozen solid, a liquid, and a gas. When heat is applied to a frozen solid, it becomes a liquid. When applied to the liquid, it becomes vapor. This elementary ...

Understanding the properties that control surface dissipation of heat could lead to improved power plants and electronics with high heat-transfer rates. A team of MIT researchers has succeeded in ...

Legions of viruses that infect the leaves of tobacco plants could be the key to making power plants safer, heating and cooling of buildings more efficient, and electronics more powerful. These tiny ...

In direct systems, the fuel is synthesised directly at the point of light absorption. This means that the sun's energy is utilised directly to produce the fuel. In indirect systems, on the other hand, ...

You are designing an LED lighting solution that is getting very hot. In what ways could the heat be transferred? Conduction – the transfer of heat between adjacent molecules of a material, usually a ...
