Scientists use molecular layers to study nanoscale heat transfer

Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide ...

Ancient effect harnessed to produce electricity from waste heat

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind ...

Atlantis crew inspects 'thermal protection system'

The Atlantis crew on Saturday inspected the craft's thermal protection system, the outer barrier that protects it from the searing heat upon re-entry into the earth's atmosphere, NASA said.

The fine art of etching

(PhysOrg.com) -- They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. ...

MEMS thermal sensor detects pre-atherosclerotic lesions

A new study published in the Annals of Biomedical Engineering shows that a MEMS thermal sensor deployed by an angiogram catheter can detect the earliest stages of atherosclerosis. The MEMS thermal sensor used convective heat ...

Pressure sensors on alert

Vacuum panels are particularly good for insulating buildings -- as long as the vacuum does not leak. A tiny pressure sensor constantly checks the condition of the vacuum and indicates whether the insulation effect is still ...
