Electrically Polarised Electrodes in DMSO and DMF electrolytes of Pseudohalide Salts: In situ IR studies supported by EXAFS/XANES and other techniques
… X-ray absorption near edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) were used to obtain direct information on the coordination state of electrogenerated products. From EXAFS/XANES data, the Ni(II)/NCS⁻ and NCSe⁻ complexes were confirmed to be octahedral …

Photocatalytic thin films: their characterisation and antimicrobial properties
… microscopy, X-ray photoelectron spectroscopy and EXAFS/XANES. Photocatalysis and film hydrophilicity were investigated using established methods. Stearic acid photodegradation, monitored by FT-IR was used to assess film photocatalysis, by monitoring the peak areas of the C-H stretching region. …

Spectroscopic and functional models for Hmd hydrogenase
… enzyme. The CN- derivative was characterized by EXAFS, XANES, and IR spectroscopy and all demonstrated a remarkable similarity to CN- inhibited Hmd. Protonation of the thiolate in Hmd has been proposed, and we examined protonation of the tricarbonyl monomer. The product was unstable even at -30 …

A Theoretical and Experimental Investigation of the Physical and Chemical Properties of Solid Nanoscale Interfaces
With the emerging interest in nanoscale materials, the fascinating field of surface science is rapidly growing and presenting challenges to the design of both experimental and theoretical studies. The primary aim of this dissertation is to shed some light on the physical and chemical properties of …

Geometrical and electronic structure of metal oxide nanoparticles on silica and alumina
… to provide surrogates for fly ash. We collected XANES and EXAFS data, which are useful for characterizing disordered mixtures where the metal is a minor component. The effect of particle size on structural properties was studied with copper oxide nanoparticles on fumed silica. XANES data …

X-RAY CHARACTERIZATION OF PLATINUM GROUP METAL CATALYSTS
Platinum group metals (PGMs) are used extensively as catalysts, employed in several sectors of the world energy economy. Fuel cells employing PGM catalysts show promise as power sources in the proposed hydrogen economy, using alcohols as hydrogen storage media. Currently, the most economically …
