Better thermal-imaging lens from waste sulfur
Thu, 17 Apr 2014 19:20:04 EDT
A new chemical process can transform waste sulfur into lightweight plastic lenses that have a high refractive index and are transparent to mid-range infrared light. The lenses may have applications in thermal imaging devices. Other potential applications for the new plastic include sulfur-lithium batteries.
Surprising material could play huge role in saving energy: Tin selenide is best at converting waste heat to electricity
Thu, 17 Apr 2014 12:45:19 EDT
One strategy for addressing the world's energy crisis is to stop wasting so much energy when producing and using it, such as in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices, with potentially enormous energy savings.
Patented research remotely detects nitrogen-rich explosives
