Flexible, transparent electronics are closer to reality with the creation of graphene-based electrodes. Researchers have created thin films that could revolutionize touch-screen displays, solar panels and LED lighting.
(PhysOrg.com) -- Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to ten times greater efficiency and power than other devices in its class. And it
After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements — a finger pinch now en route to a pulse beat in the future — to generate electricity. Speaking here today at the 241st National Meeting & Exposition of the American Chemical Society, they described boosting the device
A breakthrough in producing light emitting diodes could bring LED production costs down as much as 75.
In the first published critical review of technical developments related to electronic paper devices (i.e., e-readers like the Amazon Kindle), experts review the next generation of these devices.
A new alloy material that can convert waste heat directly into electricity has been developed by researchers at the University of Minnesota College of Science
Researchers at the University of Illinois at Urbana-Champaign have developed a three-dimensional nanostructure for battery cathodes that allows for dramatically
(PhysOrg.com) -- Ultrasensitive electronic skin developed by Stanford researcher Zhenan Bao is getting even better. Now she
Most people cross borders such as doorways or state lines without thinking much about it. Yet not all borders are places of limbo intended only for crossing. Some borders, like those between two materials that are brought together, are dynamic places where special things can happen. For an electron moving from one material toward the other, this space is where it can join other electrons, which together can create current, magnetism or even light. Researchers have made fundamental discoveries at the border regions, called interfaces, between oxide materials.
Scientists have demonstrated a clever way of controlling electrical conductance of a single molecule, by exploiting the molecule
How does a scientist fuel his enthusiasm for chemistry after 60 years? By discovering a new energy source, of course.
In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow the movement of a charge. Perhaps most importantly, the surfaces of topological insulators enable the transport of spin-polarized electrons while preventing the
Researchers have discovered a new way of splitting layered materials to give atom-thin nanosheets.This has led to a range of novel two-dimensional
