In this work, polyacrylonitrile (PAN) -based activated carbon fibers (ACFs) were developed by the common processes of stabilization, carbonization, and steam activation. Those fibers were successively subjected to heat treatment in a vacuum at high temperature and reactivation in steam. The changes

โฆ Synopsis
Ah&act-Various applications of X-ray photoelectron spectroscopy (XPS) for carbon fiber are described.
Car~ni~tion process on surface of fiber is tracked by XPS as variation of elemen~i composi~n and also of chemical species revealed by chemical shift in XPS spectra as shown in Pig. 2. Surface oxidation and also high temperature treatment of carbon fiber are also examined as shown in Table 3. Chemically heterogeneous structure of carbon fiber is studied by XPS depth profiling by utilising an Ar+ etching gun as shown in Fig. 7.

X-ray photoelectron spectroscopy (XPS) has been used to determine the species present in urban particulate matter collected in the city of Cagliari (Sardinia, Italy) and in an industrial area near to Cagliari. Samples were collected on both cellulose and glass fiber filters. Elemental identification
Soot generated from an acetylene/air premixed flame stabilized over a flat flame burner and collected on a silver substrate was studied by ESCA. Effects of equivalence ratios on the surface-adsorbed oxygenated complexes were investigated. It was concluded that finer soot particles, generated at lowe
Electrical charging of insulating samples during XPS is of direct concern for referencing the binding energy scale. Results are presented on charging of composite insulating samples that consist of an organic overlayer of polystyrene (PS) or polydimethylsiloxane (PDMS) deposited on NaCl particles. T
