## Abstract Xβray photoelectron spectroscopy (XPS) was used to study the hydrolytic aging of polypropylene according to the pHs of degrading buffer solutions and the time of aging. The study was concentrated over periods of 3, 6, and 9 months for values of pH close to the real environments of use o

This paper describes the characterization by x-ray photoelectron spectroscopy (XPS) of several Ge-doped silica glasses before and after reactive ion etching (ME) in sulphur hexafluoride (SF,). These glasses have been commonly used in the production of optical waveguides, with varying amounts of GeO,
