Nanoconfined water exhibits various interesting properties, which are not only of fundamental importance but also practical use. Because reverse micelles (RMs) provide versatile ways to prepare nanoconfined water, the understanding their physicochemical properties is essential for developing efficient applications. Although in RMs could be affected by its interaction with RM interface, details ...

This work reviews the contributions of author to developments and applications Photoelectron Spectroscopy (PES) X-ray Absorption Fine Structure (XAFS) materials studies. Focusing on Angle resolved PES (ARPES) energy distribution is discussed for angle-resolved photoemission from valence bands single crystals. The important influence spectrometer angle acceptance results (XPS) investigated in de...

This issue brings together papers from the 11th International conference on X-ray Absorption Fine Structure (XAFS XI) held in Ako, near SPring-8, in July 2000. This is one of the major synchrotron radiation conferences, held every two years since 1981 when the ®rst international meeting of XAFS experts was held in Daresbury, coincident with the operation of the ®rst of the second-generation ded...

The temperature-programmed reduction of MoO3 from 300 K to 773 K in 50 vol-% hydrogen in He (10 Pa) at different heating rates (0.1, 0.2, and 5 K/min) was investigated by in situ XRD and XAFS. At heating rates of ~ 0.1 and ~ 0.2 K/min the formation of the molybdenum bronze H0.34MoO3 was observed by in situ XRD in the early stage of the reduction of MoO3. At a heating rate of 5 K/min the formati...

We describe an advanced setup for time-resolved x-ray absorption fine structure (XAFS) spectroscopy with picosecond temporal resolution. It combines an intense femtosecond laser source synchronized to the x-ray pulses delivered into the microXAS beamline of the Swiss Light Source (SLS). The setup is applied to measure the short-lived high-spin geometric structure of photoexcited aqueous Fe(bpy)...

Apparent mismatch between XAFS and XRD structure of crystalline and amorphous electrochromic WO3 Alain Michalowicz, Jacques Moscovici, Aline Rougier, Stephane Laruelle Institut de Chimie et des Materiaux Paris Est, Universite Paris 12 and CNRS, 2 rue Henri Dunant, Thiais, France, 94320, France, Laboratoire de Reactivite et Chimie des Solides, Universite de Picardie Jules Vernes, 33 rue Saint Le...

The local structures of U(V1) oxide precipitates produced as a function of LiOH concentration have been studied by XAFS. Curve-fitting analyses indicate that the solid formed in 0.1 M LiOH is similar to a schoepite-like phase where distinct linear uranyl ions (UO?) are bridged along the equator by OH ions. At higher LiOH concentrations, the uranyl groups become elongated and the precipitate str...
