The initial biocompatability of titanium (Ti) implants is associated with surface and not bulk properties; hence surface characterization of these implants is critical for their clinical success. A goal of this study was to characterize the Ti (ASTM

We have measured the CVV Auger spectra of Fe and S from FeS 2 and compared them, after deconvoluting, with results from other techniques and with band structure calculations. These Auger spectra exhibit a number of interesting features, including a s
