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 ...

Clothing fabric keeps you cool in the heat

(Phys.org)—Researchers have designed a thermal regulation textile that has a 55% greater cooling effect than cotton, which translates to cooler skin temperatures when wearing clothes made of the new fabric. The material ...

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.

Converting heat into electricity with pencil and paper

Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive ...

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 ...

Scientists demonstrate a high-efficiency ceramic laser

(PhysOrg.com) -- Scientists in the Optical Sciences Division at the Naval Research Laboratory, report a successful demonstration of a novel high-efficiency ceramic laser that is both, light-weight and compact for use in both ...

A new semiconductor with record-high thermal conductivity

Scientists at UCLA, for the first time, experimentally realized a new compound single crystal, boron arsenide (BAs) and explored its thermal conductivity limit when crystals are free of defects. They observed the highest ...
