In physics, thermal conductivity (often denoted k, Î», or Îº) is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier's Law for heat conduction.
Since they were first invented in 1931, aerogels have become widely used in the industry, mostly for insulation purposes, thanks to their low thermal conductivity and light weight. Traditional silica aerogels, however, are brittle and obtuse, typically unsuited for applications where flexing of the material would occur. A novel class of polymer aerogels seeks to fix [...]
Researchers at North Carolina State University have developed a new technique of cooling electronic devices which they claim and prove through their findings that it can lead to an increase of performance by improving the rate of heat exchange, while also lowering the cost of manufacturing. The scientists’ findings might lead to a new generation [...]
Xinwei Wang, an associate professor of mechanical engineering at Iowa State studies thermal conductivity – and he had a funny feeling about spiders; so he ordered eight spiders — Nephila clavipes, golden silk orbweavers — and put them to work eating crickets and spinning webs in the cages he set up. Wang has been looking for organic [...]
