Researchers have discovered a novel solid state reaction which lets kesterite grains grow within a few seconds and at relatively low temperatures. For this reaction they exploit a transition from a metastable wurtzite compound in the form of nanorods to the more stable kesterite compound.
The sixth annual BBVA Foundation Frontiers of Knowledge Award in the Basic Sciences category goes to German physicists Maximilian Haider , Harald Rose and Knut Urban for 'greatly enhancing the resolving power of electron microscopy by developing aberration-corrected electron optics, a breakthrough enabling subatomic precision'.
Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathogens.
Scientists describe the results of their theoretical study of the extent to which it is possible to extract information on the wave function of complex oxides using resonant X-ray techniques. The specific oxides considered by the team are those subject to strong spin-orbit coupling.
Physicists at the University of Arkansas and their collaborators have engineered novel magnetic and electronic phases in the ultra-thin films of in a specific electronic magnetic material, opening the door for researchers to design new classes of material for the next generation of electronic and other devices.
From the world of nanotechnology we've gotten electronic skin, or e-skin, and electronic eye implants or e-eyes. Now we're on the verge of electronic whiskers. Researchers with Berkeley Lab and the University of California (UC) Berkeley have created tactile sensors from composite films of carbon nanotubes and silver nanoparticles similar to the highly sensitive whiskers of cats and rats.
