Ever stop to consider why lotus plant leaves always look clean? The hydrophobic – water repelling – characteristic of the leaf, termed the "Lotus effect," helps the plant survive in muddy swamps, repelling dirt and producing ...
The electrochemical reactions inside the porous electrodes of batteries and fuel cells have been described by theorists, but never measured directly. Now, a team at MIT has figured out a way to measure the fundamental charge ...
Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.
(Â鶹ÒùÔº) —Hydrogen is a "green" fuel that burns cleanly and can generate electricity via fuel cells. One way to sustainably produce hydrogen is by splitting water molecules using the renewable power of sunlight, but scientists ...
(Â鶹ÒùÔº) —Hydrogen is used as an energy source in fuel cells and can be produced from water by using sunlight and a suitable catalyst. In the journal Angewandte Chemie, American researchers have now introduced a new electrocatalyst ...
Three pieces of less than 1 mm in size each may be put together to the probably smallest puzzle in the world. For production, researchers used LIGA2.X, a new process to manufacture microstructured casting molds at KIT's ANKA ...
An advance in micromotor technology akin to the invention of cars that fuel themselves from the pavement or air, rather than gasoline or batteries, is opening the door to broad new medical and industrial uses for these tiny ...
Imagine if you could drink a glass of water just by inserting a solid wire into it and sucking on it as though it were a soda straw. It turns out that if you were tiny enough, that method would work just fine—and wouldn't ...
Researchers have shown theoretically how to control or eliminate the formation of "dendrites" that cause lithium-ion batteries to fail, an advance that if realized would improve safety and might enable the batteries to be ...
A new way of making crystalline silicon, developed by U-M researchers, could make this crucial ingredient of computers and solar cells much cheaper and greener.
