A researcher from Missouri University of Science and Technology has developed a new way to grow nanowire arrays with a determined diameter, length and uniform consistency. This approach to growing nanomaterials will improve ...
(Phys.org) —With so much of our 21st century technology dependent on ever smaller and more efficient re-chargeable lithium-ion (Li-ion) batteries, finding new ways to non-destructively peer inside an operating battery is ...
(Phys.org) —Researchers at Missouri University of Science and Technology have developed what they call "a simple, one-step method" to grow nanowires of germanium from an aqueous solution. Their process could make it more ...
(Phys.org) —Cornell chemical engineers have achieved a breakthrough in the race to achieve safer, longer-lasting batteries to power the world's automobiles, cell phones, computers and autonomous robots.
One of the challenges for the commercialization of polymer electrolyte fuel cells (PEFCs) is the development of new cathode catalysts for the oxygen reduction reaction (ORR) that exhibit superior activity and durability than ...
The ability to create conducting polymer films in a variety of shapes, thicknesses and surface properties rapidly and inexpensively will make growing and testing cells easier and more flexible, according to a team of Penn ...
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.
(Phys.org) —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 ...
