Air Lubrication For Ships Hulls Saves Energy
September 7, 2016 | 3 Comments
University of Twente researchers found injecting bubbles underneath a ship’s hull causes them to be pushed against the hull’s surface making an air bearing surface. In the surface layer between the ship and water, these air bubbles cause less friction: it’s also known as air lubrication. In practice, friction can be reduced 20 percent, with […]

Tough New Catalyst Splits Water 100 Times Faster
September 6, 2016 | Leave a Comment
Researchers at Stanford and the SLAC National Accelerator Laboratory have developed a tough new catalyst that carries out solar-powered water molecule splitting 100 times faster. This tough new catalyst works better as time goes on and stands up to acid. Because the new catalyst requires less of the rare and costly metal iridium, it could […]

A Better Lithium Ion Battery Anode Found
September 1, 2016 | Leave a Comment
The National Institute for Materials Science (NIMS) researchers have developed an anode material for lithium-ion rechargeable batteries by forming nanoparticles made of silicon metal composites on metal substrates. The resulting anode material has a high capacity – almost twice as high as conventional materials – and a long cycling life. The results could lead to […]
