Valence-band x-ray photoelectron spectroscopic studies of manganese and its oxides interpreted by cluster and band structure calculations

Autor: Peter M. A. Sherwood, Ahmad Ali Audi

Publikováno v: Surface and Interface Analysis. 33:274-282

Valence-band and core-level x-ray photoelectron spectroscopy (XPS) of manganese and its oxides is reported and the valence-band spectra are interpreted by various calculation models. The focus of this paper is on the valence band, which shows signifi

X-ray photoelectron spectroscopic studies of sulfates and bisulfates interpreted by X? and band structure calculations

Autor: Ahmad Ali Audi, Peter M. A. Sherwood

Publikováno v: Surface and Interface Analysis. 29:265-275

Valence-band and core-level x-ray photoelectron spectroscopy (XPS) studies of sulfate and bisulfate ions are reported. Sulfate and bisulfate ions cannot be distinguished in their core XPS spectra. The valence band region shows a significant differenc

X-ray Photoelectron Spectroscopic Studies of Carbon Fiber Surfaces. 22. Comparison between Surface Treatment of Untreated and Previously Surface-Treated Fibers

Autor: Peter M. A. Sherwood, Yuqing Wang, and Ahmad Ali Audi, Hema Viswanathan

Publikováno v: Chemistry of Materials. 12:1100-1107

IM7 PAN-based carbon fibers, with a proprietary surface treatment applied by the manufacturer, were analyzed by X-ray photoelectron spectroscopy (XPS). The surface treatment applied by the manufacturer was removed by heating in a vacuum. The fibers d

Electrochemical characterization of recessed nanodisk-array electrodes prepared from track-etched membranes

Autor: Gregory P. Dible, and Ahmad Ali Audi, Takashi Ito

Publikováno v: Analytical chemistry. 78(19)

Recessed nanodisk-array electrodes (RNEs) fabricated from track-etched polycarbonate membranes (TEPCMs) having cylindrical nanopores (50 nm in diameter) were characterized using cyclic voltammetry (CV). Such electrodes were prepared by depositing a g
