Scientists in China have designed a photovoltaic-thermal integrated air-source heat pump hot water system that uses a phase change tank to lower energy consumption and achieve higher power generation ...

Two memory bits shown in their “off” and “on” states (false color image based on topographic profile from atomic force microscopy). The “off” state shows the carbon nanotube electrodes disconnected.

Scientists have used pressure with a twisting shear to permanently deform silicon, an important material for electronics. The resulting changes in silicon's microstructure produce material phases that ...
