Rate Constants for Reactions of Phenoxyl Radicals in Solution

March 1, 2005
Author(s)
Pedatsur Neta, J Grodkowski
Absolute rate constants for reactions of phenoxyl radicals in solution have been compiled and evaluated from the literature. Rate constants are included for phenoxyl radicals bearing various substituents, including semiquinone radicals and radical ions, as

Ionization of W and W+ by Electron Impact

October 12, 2021
Author(s)
D H. Kwon, Y J. Rhee, Yong Sik Kim
… electron-impact ionization of the neutral W atom and W$^+$ ion are reported. The direct ionization cross sections were …

Structure and Reactivity of the Hydrated Hematite (0001) Surface

October 12, 2021
Author(s)
T P. Trainor, Anne M. Chaka, P J. Eng, M Newville, G A. Waychunas, J G. Catalano, G E. Brown
Hematite (alpha-Fe 2 O 3 ) is significantly more reactive to water and metal ions than its isostructure corundum (alpha-Al 2 O 3u) under environmental conditions. However, the reason for this difference is not understood. Using crystal truncation rod

Ultrafast modulation of x-ray absorption by coherent phonon excitations

February 1, 2017
Author(s)
Eric L. Shirley, Jannick Weisshaupt, Michael Woerner, Marc J. Vrakking, Thomas Elsaesser, Andreas Borgschulte
X-ray absorption in solids promotes an electron from an atomic core level to the conduction band states, and near-edge spectra structure gives insight into local atomic geometry and chemical bonding effects. Based on a novel implementation of femtosecond x

Electric Field Control of Interfacial Ferromagnetism in CaMnO 3 /CaRuO 3 Heterostructures

July 24, 2015
Author(s)
Alexander J. Grutter, Brian J. Kirby, M. T. Gray, C. L. Flint, U. S. Alaan, Y. Suzuki, Julie A. Borchers
A key milestone for the development of low-power spintronic devices is electric field control of ferromagnetism. To that end, we have probed the electric field dependence of the emergent ferromagntic layer at CaRuO 3/CaMnO 3 interfaces in bilayers

Physical Properties of LiMn 2-x MxO 4 (M = Ni, Fe) Sol-Gel Nanopowders

December 15, 2014
Author(s)
E. Talik, L. Lipinska, A. Guzik, Pawel Zajdel, M. Michalska, M. Szubka, M. Kadziolka-Gawel, Rick L. Paul
The Pechini sol-gel method was applied to obtain LiMn 2-xT xO 4 (T=Ni, Fe; x = 0.1 to 0.5) nanopowders. Crystal and electronic structures, chemical composition and magnetic properties of the materials were characterized by X-ray diffraction, XPS, SEM/EDX
