A collaborative research team, including Los Alamos National Laboratory, University of Stuttgart (Germany), University of New Mexico, and Sandia National Laboratories, has developed a proton conductor for fuel cells based on polystyrene phosphonic acids that maintain high protonic conductivity up to 200 C without water.
A recent study has measured the internal quantum efficiency (IQE) of Zinc-Oxide (ZnO) crystals in both the light-emitting process and non-light-emitting process.
The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks.
An atomic mechanism unraveled by materials scientists from Duke University ensures that specific thermoelectric materials are extremely efficient close to high-temperature phase transitions.
A touch of gold - or another noble metal – can change the structure of a crystal and its intrinsic properties, physicists at the University of Warwick have demonstrated in a display of modern-day alchemy.
Over the last decade, the field of condensed matter physics has experienced a golden age with the discovery of new materials and properties, and related technologies being developed at breakneck speed thanks to the arrival of topological physics. Topological physics took off in 2008 with the discovery of topological insulator, a type of material that is electrically insulating in the bulk but metallic on the surface.
Researchers at the Faculty of Physics, University of Warsaw, used the liquid crystal elastomer technology to demonstrate a series of micro-tools grown on optical fibers. The 200-micrometer gripers are controlled remotely, without electric wiring or pneumatic tubing, with green light delivered through the fibers - absorbed light energy is directly converted into the gripper jaws' action.
Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current.
Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile's skin a rainbow of colors.
A team of scientists at the University of Vermont have invented a new tool--they call it a "nanocage"--that can catch and straighten out molecule-sized tangles of polymers.
