XSW-XAFS characterization of ion-irradiatedPt/Ni/Cmultilayer

XAFS analysis of triiodide ion in solutions.

Iodine K-edge XAFS of triiodide ions in various solvents were measured at SPring-8 BL01B1 and analyzed. Though the anion takes a linear and symmetric form, the second peak expected from enhanced multiple scatterings can be hardly observed because of its large vibrations. The bond distances and the Debye-Waller factors for the I-I couple vary when protic solvents were used and they were similar ...

XAFS Studies of Silver Environments in Ion-Exchanged Glasses

The X-ray absorption fine structure (XAFS) technique was used to analyze the structural geometry of Ag atoms introduced into soda-lime silicate glass and soda aluminosilicate glass by ion-exchange methods. The results show that Ag ions in aluminosilicate glass are coordinated by about two oxygens and the nearest-neighbor Ag-O distance increases when the Ag-for-Na ion-exchange ratio is larger th...

Structural Characterization of Intercalated C2Fx Compounds Using XAFS Polarization Dependencies

Orientation dependencies of FeK, BrK EXAFS and XANES spectra have been measured for intercalated compounds of the composition CZF, *yA (X = 1 . A= Brz, BrF3, FeBr3, Fe(AA)3, FeCl3) synthesized by dityusion from solutions. An approach has been developed which allows determination of the ranges of the orientation angles of T-shaped BrF3 molecules tiom XANES spectra. The values of the orientation ...

Characterization of Lithium Ion Transport Via Dialysis Process
