Photovoltaics from any semiconductor
A technology that would enable low-cost, high efficiency solar cells to be made from virtually any semiconductor material has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence ...
Team observes real-time charging of a lithium-air battery
One of the most promising new kinds of battery to power electric cars is called a lithium-air battery, which could store up to four times as much energy per pound as today's best lithium-ion batteries. But ...
Pyroelectric nanogenerator charges Li-ion battery with harvested energy
Nanoscale optical switch breaks miniaturization barrier
(Phys.org) —An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer products ranging from cell phones to automobiles.
Excitons: Exotic particles, chilled and trapped, form giant matter wave
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.
Scientists enhance light emission in 2D semiconductors by a factor of 100
The molecule 'scanner': The world's smallest terahertz detector
Molecules could soon be "scanned" in a fashion similar to imaging screenings at airports, thanks to a detector developed by University of Pittsburgh physicists.
Ultra-sensitive nano-chip capable of detecting cancer at early stages developed
Today, the majority of cancers are detected on the macroscopic level, when the tumor is already composed of millions of cancer cells and the disease is starting to advance into a more mature phase. But what ...
Let there be light: Chemists develop magnetically responsive liquid crystals
Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research opens ...
Quantum dot LEDs get brighter, more efficient
Flat boron by the numbers: Researchers calculate what it would take to make new 2-dimensional material
It would be a terrible thing if laboratories striving to grow graphene from carbon atoms kept winding up with big pesky diamonds.
