(Phys.org)—Researchers have built the hottest thermal diode to date, which operates at temperatures of more than 600 K (326 °C). Thermal diodes may serve as the building blocks of future thermal computers, which could ...
(Phys.org) —Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material—strong, light, nearly transparent, and an excellent conductor of electricity and heat. But a number of ...

(PhysOrg.com) -- Matt Scullin co-founded Alphabet Energy just one year ago, but already the CEO has ambitions of turning the San Francisco-based start-up company into the "Intel of waste heat." By harnessing the waste heat ...
Unlike water, liquid refrigerants and other fluids that have a low surface tension tend to spread quickly into a sheet when they come into contact with a surface. But for many industrial process it would be better if the ...
