Abstract

X-ray absorption measurements have been performed on Zn1-xMnxO (x=.25 and x=.05) at the Mn K edge under pressure. Mn is in substitution of Zn whatever the composition or the structure. A phase transformation from wurtzite to rocksalt is observed close to 8 GPa for both compositions. The local compressibility around the Mn atom is similar to the bulk one, in the wurtzite and in the rocksalt phases. The transition is reversible for x=0.05 but irreversible for x=0.25.

X-ray absorption spectroscopy studies of the Ni ion of Li(Ni{sub 0.8}Co{sub 0.15}Al{sub 0.05}){sub 0.8}(Ni{sub 0.5}Mn{sub 0.5}){sub 0.2}O{sub 2} with a core–shell structure and LiNi{sub 0.8}Co{sub 0.15}Al{sub 0.05}O{sub 2} as cathode materials

Journal Article Cho, Sung-Woo ; Kim, Gyeong-Ok ; Ju, Jeong-Hun ; ... - Materials Research Bulletin

Core–shell materials have attracted a great deal of interest since core–shell particles have superior physical and chemical properties compared to their single-component counterparts. The cathode material Li(Ni{sub 0.8}Co{sub 0.15}Al{sub 0.05}){sub 0.8}(Ni{sub 0.5}Mn{sub 0.5}){sub 0.2}O{sub 2} (LNCANMO) with a core–shell structure was synthesized via a co-precipitation method and investigated as the cathode material for lithium ion batteries. The core–shell particle consisted of LiNi{sub 0.8}Co{sub 0.15}Al{sub 0.05}O{sub 2} (LNCAO) as the core and LiNi{sub 0.5}Mn{sub 0.5}O{sub 2} as the shell. The cycling behavior between 2.8 and 4.3 V at a current of 0.1 C-rate showed a reversible capacity of ∼195 mAh g{supmore »« less

Double conical crystal x-ray spectrometer for high resolution ultrafast x-ray absorption near-edge spectroscopy of Al K edge

Journal Article Levy, A. ; Dorchies, F. ; Fourment, C. ; ... - Review of Scientific Instruments

An x-ray spectrometer devoted to dynamical studies of transient systems using the x-ray absorption fine spectroscopy technique is presented in this article. Using an ultrafast laser-induced x-ray source, this optical device based on a set of two potassium acid phthalate conical crystals allows the extraction of x-ray absorption near-edge spectroscopy structures following the Al absorption K edge. The proposed experimental protocol leads to a measurement of the absorption spectra free from any crystal reflectivity defaults and shot-to-shot x-ray spectral fluctuation. According to the detailed analysis of the experimental results, a spectral resolution of 0.7 eV rms and relative fluctuation lowermore »« less

Pressure Induced Phase Transition in PbTiO3 Studied by X-ray Absorption Spectroscopy at the Ti K edge

Journal Article Dhaussy, A. C. ; Marinel, S. ; Veres, A. ; ... - AIP Conference Proceedings

The Ti-K edge X-ray Absorption Near Edge Structure (XANES) for CaTiO3 and PbTiO3 have been measured under high pressure in a diamond anvil cell at room temperature. Despite the huge absorption from the diamond cell and the sample high quality XANES allows us to observe that in CaTiO3 no change occurs when applying pressure, at the opposite of PbTiO3 in which the pre-edge features vary strongly. It allows studying the phase transition from ferroelectric to paraelectric phase in PbTiO3 from the local point of view. Under pressure the change in intensity of the pre-edge indicates qualitatively that the Ti atommore »« less

High resolution short focal distance Bent Crystal Laue Analyzer for copper K edge x-ray absorption spectroscopy

Journal Article Kujala, N. G. ; Barrea, R. A. ; Karanfil, C. - Review of Scientific Instruments

We have developed a compact short focal distance Bent Crystal Laue Analyzer (BCLA) for Cu speciation studies of biological systems with specific applications to cancer biology. The system provides high energy resolution and high background rejection. The system is composed of an aluminum block serving as a log spiral bender for a 15 micron thick Silicon 111 crystal and a set of soller slits. The energy resolution of the BCLA--about 14 eV at the Cu K{alpha} line-- allows resolution of the Cu K{alpha}{sub 1} and CuK{alpha}{sub 2} lines. The system is easily aligned by using a set of motorized XYZmore »« less
