Jumping droplets help heat transfer

Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. ...

Electric fields can push droplets from surfaces

Researchers at MIT have followed up on their discovery that droplets of water acquire an electric charge when jumping from certain condenser surfaces by finding a way to make use of that effect: They found that by applying ...

Droplets get a charge out of jumping

In a completely unexpected finding, MIT researchers have discovered that tiny water droplets that form on a superhydrophobic surface, and then "jump" away from that surface, carry an electric charge. The finding could lead ...

Efficient thermal cooling and heating

Thermal systems use heat to produce cold, and vice versa. To do so, a material is needed that can dissipate water vapor particularly well and quickly. A new method simply applies this property as a layer onto the components.
