✦ Synopsis

Using XPS, we have detected severaI oxygen sites on the surface of hydrated TiOz (rutite) crystals. These sites are attributed to chemisorbed and phbsisorbed HzO. XPS spectra of clean TiOz resulting from scrapins in vacuum indicate that oxygens terminate at the very surface. Imptications of these observations are discussed_ I_ introduction It is commomy recognized that metal oxide surfaces, such as those of TiO, , AI,O, , Sn02, and 2110

Coupons of polished aluminium, glass and polystyrene were exposed to radiofrequency (r.f.) plasmas containing helium, nitrogen and oxygen. Angle-resolved XPS measurements of the treated surfaces were made immediately, after a few days and after about 9 months. The data were interpreted in terms of a

Combined 15 N ssNMR and X-ray photoelectron spectroscopy (XPS) investigations for theophylline, a theophylline co-crystal, and a theophyllinium salt demonstrate that XPS allows direct observation of the degree of proton transfer, and thus identification of whether a salt or a co-crystal has been for

The surface and the solid/liquid interface of two polyamide membranes, one experimental (B0) and one commercial (NF45), have been characterized by X-ray photoelectronic spectroscopy (XPS), atomic force microscopy (AFM), and zeta potential, respectively. The surface roughness, determined by AFM data
