Interaction of methanol with well-defined ceria surfaces: reflection/absorption infrared spectroscopy, X-ray photoelectron spectroscopy, and temperature-programmed desorption study
Article Abstract:
A study investigated the adsorption of methanol on well ordered, well defined cerium oxide overlayers prepared on a Cu(111) substrate by the low-pressure oxidation of cerium predeposited by vacuum evaporation. A combination of temperature-programmed desorption and reflection/absorption infrared spectroscopic techniques were used in this experiment. Among other results, it was found that some Ce3+ ions are still present in the surface layers at 300 K after oxidation treatments. Other experimental findings are discussed.

Oxidation kinetics of Mg-, Si-, and Fe-implanted aluminum by using x-ray photoelectron spectroscopy
Article Abstract:
A study was conducted to analyze the oxidation characteristics of magnesium, silicon and iron-implanted aluminum. X-ray photoelectron spectroscopy was utilized to carry out the analysis. The elements were implanted into high-purity aluminum at low ion doses. The effects of surface damage caused by the ion beam during the implantation process was then examined. Results indicated that the addition of magnesium and silicon lowered and enhanced the oxidation rate, respectively.

Investigation of solid surfaces modified by Langmuir-Blodgett monolayers using sum-frequency vibrational spectroscopy and x-ray photoelectron spectroscopy
Article Abstract:
Langmuir-Blodgett monomolecular layers of alkylhydroxamic acids and alkylphosphonic acids on copper and iron substrates are studied by X-ray photoelectron spectroscopy (XPS) and sum-frequency vibrational spectroscopy. According to XPS results, the structures of the hydroaxmic acid and phosphonic acid Langmuir-Blodgett films are very similar.
