Scientists Make Temperature-Regulating Coffee Mug

(PhysOrg.com) -- A well-insulated mug may keep your coffee somewhat warm, but now scientists have designed a high-tech mug that can keep drinks hot or cold at the perfect temperature for up to half an hour.

Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

At the edge of chaos, powerful new electronics could be created

A phenomenon that is well known from chaos theory was observed in a material for the first time ever, by scientists from the University of Groningen, the Netherlands. A structural transition in the ferroelastic material barium ...

'Nano-pixels' promise thin, flexible, high resolution displays

A new discovery will make it possible to create pixels just a few hundred nanometres across that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, ...

Cheap beads offer alternative solar-heating storage

A cheap material that can store heat energy collected from the sun during the day that can be released slowly over night has been developed by researchers in the India. The material based on paraffin wax and stearic acid ...

Sunflowers inspire more efficient solar power system

(Phys.org) -- A field of young sunflowers will slowly rotate from east to west during the course of a sunny day, each leaf seeking out as much sunlight as possible as the sun moves across the sky through an adaptation called ...

Improving energy storage with a cue from nature

Materials melt faster when the lines of heat spread through the cold material like the branches of a tree—and the melting rate can be steadily increased by allowing the tree architecture to freely evolve over time, researchers ...
