Open Image…Save ImageOpen Image (using #TmpD/ia)… New research led by the University of Pittsburgh unveiled the atomic-scale friction of a single tungsten asperity, or rough edge, in real time, showing atomic motion for the first time using electron microscopy. For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce […]

A Hokkaido University team has found a thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600° C, opening new avenues towards the widespread use of thermoelectric converters. The team led by Professor Hiromichi Ohta at the Research Institute for Electronic Science at Hokkaido University synthesized a barium cobalt oxide thermoelectric […]

Chalmers University of Technology scientists have pioneered a recycling method that is inspired by the natural carbon cycle and could eliminate the climate impact of plastic materials. Can replace fossil raw materials Henrik Thunman, Professor of Energy Technology at Chalmers University of Technology and one of the authors of the study published in the Journal […]

American Institute of Physics researchers have constructed a photovoltaic cell that works both day and night by making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperatures a few degrees below the ambient air. The device under development uses a thermoelectric […]

Massachusetts Institute of Technology engineers have developed a heat engine with no moving parts that is more efficient than a steam turbine. The researchers say the design could someday enable a fully decarbonized power grid. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than […]
