(Phys.org) —When hydrogen is produced from water during electrolysis, some energy is lost as tiny bubbles. In a new study, researchers have demonstrated that 25-nm transistors—so small that they're considered zero-dimensional ...
(Phys.org) -- Mechanical energy is all around us, whether in the form of a vehicle's vibrations, ocean waves, or vibrating train tracks. However, much of this energy is irregular and oscillatory - for example, road bumps ...
(PhysOrg.com) -- In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial ...
(PhysOrg.com) -- Due to the increasing demand for renewable energy sources, photovoltaic solar cells have advanced significantly over the past decade. Since 2002, photovoltaic production worldwide has been doubling every ...
Researchers led by the University of Manchester have designed a catalyst that converts biomass into fuel sources with remarkably high efficiency and offers new possibilities for manufacturing advanced renewable materials.

(Phys.org)—Toulouse-based Airbus, a world-leading aircraft manufacturer, has issued its "vision" of what truly smart flying—smart, that is, as in sustainable rather than smart as in sensor-packed—will be like in 2050. ...
Contrary to common perception, the major automakers have produced large increases in fuel efficiency through better technology in recent decades. There’s just one catch: All those advances have barely increased the mileage ...
