Technique could prevent overheating of laptops, mobile phones, and other electronics. Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup […]
In a time-lapse sequence, infrared imaging shows the temperature changes within a droplet of water as it moves across a treated silicon surface in response to temperature differences on that surface. Image courtesy of N. […]
Counterintuitive “metamaterial” may enable heat-resistant circuit boards. Almost all solid materials, from rubber and glass to granite and steel, inevitably expand when heated. Only in very rare instances do certain materials buck this thermodynamic trend […]
Carbon nanotubes lower the transformation temperature of glassy carbon, possibly aiding manufacturers, MIT researchers report. Last winter, MIT researchers discovered that a phenol-formaldehyde polymer transformed into a glassy carbon material in a process similar to baking […]
