The development of new organic batteries - lightweight energy storage devices that work without the need for toxic heavy metals - has a brighter future now that chemists have discovered a new way to pass electrons back and forth between two molecules.
The 'Electronic Transport in Nanoengineered Materials' workshop is sponsored by UChicago's Materials Research Science and Engineering Center. Among the approximately 70 participants will be physical chemists, who make new materials and study their properties, and theoretical physicists who specialize in the study of solid matter.
New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products.
The PhD thesis by Carlos Echeverria Arrondo, Doctor in Physics from the Public University of Navarre and entitled 'On doped semiconductor quantum dots and magnetic nanowires', studied the behaviour and properties of nanometric-scale semiconductor crystals.
Researchers from the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the University of California at Berkeley, and the Vavilov State Optical Institute in St. Petersburg, Russia, have now made sensitive measurements of magnetic fields by maintaining the spin polarization of atoms in an alkali-vapor magnetometer for more than 60 seconds at room temperature - a two-orders-of-magnitude improvement in this important measurement parameter over the best previous performance.
As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy's Oak Ridge National Laboratory is providing an unprecedented perspective on how lithium-ion batteries function.
A new genre of construction materials, made with particles barely 1/50,000th the width of a human hair, is about to play a big role in the building of homes, offices, bridges, and other structures, according to the latest episode in the American Chemical Society's award-winning podcast series, 'Global Challenges/Chemistry Solutions'.
New research uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS can resolve dimensions as small as a single wavelength of the light.
