Plastic Material Works as a 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 casings for laptops and mobile phones that overheat, in part, because the...

Two-photon lithography (TPL), a high-resolution 3D printing technique, is capable of producing nanoscale features smaller than 1/100 the width of a human hair. The technique could enable X-ray...

Water heaters and other thermal energy storage devices increase the temperature of a medium above an ambient or normal temperature, and store the warmer medium. Water heaters, in particular, must store...

Laser engineers are leveraging new materials, unusual gain mechanisms, and innovative cavity designs to push laser performance into new regimes. Pulse lengths are getting...
