Captain America's shield is famous for absorbing tremendous amounts of kinetic energy, from an artillery shell to a punch from the Hulk – keeping Cap not only safe, but on his feet. What's going on here?
Based on a fundamental chemical discovery by scientists at Oregon State University, it appears that trees may soon play a major role in making high-tech energy storage devices.
"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much smaller package. In AIP ...
(Phys.org) —Advances in flexible and stretchable electronics have prompted researchers to explore ways to create stretchable supercapacitors—robust energy storage devices—to power these and other devices.
Researchers report that wood-biochar supercapacitors can produce as much power as today's activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts.
(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.
New types of nanostructures have shown promise for applications in electrochemically powered energy devices and systems, including advanced battery technologies.
Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device.
(Phys.org) —A new material that can store large amounts of energy with very little energy loss has been developed by researchers at the Australian National University.
(Phys.org) —Waste from textile and paint industries often contains organic dyes such as methylene blue as pollutants. Photocatalysis is an efficient means of reducing such pollution, and molybdenum trioxide (MoO3) catalyzes ...
