Scientists from Stanford and Illinois have created a heat-resistant thermal emitter that could significantly improve solar cell efficiency. The novel component is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity - a technology known as thermophotovoltaics.

Read moreComparable to nanoscale Navy Seals, Cornell scientists have merged tiny gold and iron oxide particles to work as a team, then added antibody guides to steer the team through the bloodstream toward colorectal cancer cells. And in a nanosecond, the alloyed allies then kill the bad guys - cancer cells - with absorbed infrared heat.

Researchers are aiming to use ocean waves to produce energy by making use of contact electrification between a patterned plastic nanoarray and water. They have introduced an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy and as a chemical or temperature sensor.
