Better surfaces could help dissipate heat

Cooling systems that use a liquid that changes phase — such as water boiling on a surface — can play an important part in many developing technologies, including advanced microchips and concentrated solar-power ...

Researcher Uses Graphene Quilts to Keep Things Cool

(PhysOrg.com) -- University of California, Riverside Professor of Electrical Engineering and Chair of Materials Science and Engineering Alexander Balandin is leading several projects to explore ways to use the unique capabilities ...

From crystals to glasses: a new unified theory for heat transport

Theoretical physicists from SISSA and the University of California at Davis have developed a new approach to heat transport in materials, which finally allows crystals, polycrystalline solids, alloys and glasses to be treated ...

Tides could be source of heat on icy moons

The icy moons in the outer solar system hold the potential for life, given that they may contain oceans of water. But life also needs a source of energy input to perform essential functions such as growth, reproduction and ...

Engineered 'sand' may help cool electronic devices

Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry ...

Infrared video reveals how hummingbirds dissipate heat

(Phys.org)—A team of researchers with George Fox University in Oregon and the University of Montana has uncovered the ways in which calliope hummingbirds (Selasphorus calliope) get rid of the large amount of heat that is ...

Graphene meets heat waves

EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key ...
