New polymer films conduct heat instead of trapping it

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat.

Engineers turn plastic insulator into heat conductor

Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic ...

For this metal, electricity flows, but not the heat

There's a known rule-breaker among materials, and a new discovery by an international team of scientists adds more evidence to back up the metal's nonconformist reputation. According to a new study led by scientists at the ...

Can heat be controlled as waves?

A growing interest in thermoelectric materials—which convert waste heat to electricity—and pressure to improve heat transfer from increasingly powerful microelectronic devices have led to improved theoretical and experimental ...

Ultrafast heat conduction can manipulate nanoscale magnets

Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in ...

Squeezing out new science from material interfaces

With more than five times the thermal conductivity of copper, diamond is the ultimate heat spreader. But the slow rate of heat flow into diamond from other materials limits its use in practice. In particular, the physical ...

Physicists show unlimited heat conduction in graphene

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the National University of Singapore have attested that the thermal conductivity of graphene diverges with the size of the samples. This discovery ...
