Researchers at the Vienna University of Technology have revealed that the missing iron atoms in Magnetite’s (Fe3O4) sub-surface layer govern its properties. "It turns out that the surface of Fe3O4 is not Fe3O4 at all, but rather Fe11O16," says Professor Ulrike Diebold, head of the metal-oxide-research group at TU Wien (Vienna).
An eco-friendly, cost-effective process to produce lactic acid from glycerol has been developed by research groups at ETH Zurich. Glycerol is a waste by-product that is obtained during production of biodiesel.
Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have combined standing-wave photoelectron spectroscopy (SWPS) technique with high ambient pressure photoelectron spectroscopy (APPS) technique to create standing wave ambient pressure photoelectron spectroscopy (SWAPPS) - a new technique for study of chemical elements at heterogeneous interfaces.
Scientists at the University of Wyoming (UW) are exploring ways to develop cost-effective, eco-friendly, and more efficient fuel cell technology. Although commercially available, fuel cell technology is not cost effective when compared to that of other sources of energy.
Yuriy Román, an Assistant Professor of Chemical Engineering at MIT, is leading a study on catalytic conversion of inedible plant matter into chemicals that could be used for producing fuels and useful substances. Catalysts stimulate and speed-up chemical reactions, and increase the possibility of applying the process on an industrial scale.
An international team of scientists have discovered a safe sodium-based material which could be used as a cost-effective alternative to the lithium-based conductors currently used in rechargeable batteries.
Scientists at chemist James Tour’s lab at Rice University have discovered a cost-effective method to create flexible films of molybdenum disulfide for hydrogen catalysis and energy storage applications.
A team of researchers from the Universitat Politècnica de Catalunya (UPC) have discovered that atoms react differently depending on the characteristics of the catalyst that is used.
Researchers at Brookhaven National Laboratory have performed three studies on the electrochemical reactions that occur in nickel, cobalt, and aluminum (NCA) lithium-ion batteries. They studied average material morphologies as well as atomic-scale asymmetries to analyze the electronic and structural and degradations of these batteries.
Researchers at McGill University have conducted ultrafast electron diffraction experiments to study the semiconductor-metal transition of vanadium dioxide (VO2), during which they observed the reorganizations of the atomic positions of the material and its electron distribution, simultaneously. This transformation occurs at femtosecond time scales, which is in the range of one millionth of a billionth of a second.
