(Phys.org) —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.

(Phys.org)—A research group at the National Institute of Standards and Technology (NIST) has developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms on a surface. ...
(Phys.org)—A new method for creating very thin layers of materials at the atomic scale, reported in the latest issue of the journal Science, could "unlock an important new technology" for creating nanomaterials, according ...
(Phys.org) -- Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require many processing ...
(Phys.org) -- Hydrogen is a clean fuel, producing only water vapor when it burns. But generating hydrogen in large quantities and in a “green” fashion is not straightforward.
