متن کاملSurface analysis of dental amalgams by X-ray photoelectron spectroscopy and X-ray diffraction.
OBJECTIVES It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. METHODS The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray photoelect...
متن کاملQuantitative characterization of DNA films by X-ray photoelectron spectroscopy.
We describe the use of self-assembled films of thiolated (dT)25 single-stranded DNA (ssDNA) on gold as a model system for quantitative characterization of DNA films by X-ray photoelectron spectroscopy (XPS). We evaluate the applicability of a uniform and homogeneous overlayer-substrate model for data analysis, examine model parameters used to describe DNA films (e.g., density and electron atten...

متن کاملInitial surface film on magnesium metal: A characterization by X-ray photoelectron spectroscopy (XPS) and photocurrent spectroscopy (PCS)
A detailed investigation of the initial film grown on mechanically polished Mg electrodes has been carried out by ex situ X-ray Photoelectron pectroscopy (XPS) and in situ Photocurrent Spectroscopy (PCS), allowing to reach a detailed picture of the passive layer structure. The XPS ata show that the films formed soon after mechanical treatment and immersion in aqueous electrolyte have a bilayer ...
