Monochromated X-ray photoelectron

The interaction of adsorbed thiol molecules with gold nanoparticles as a function of the mean particle size has also been studied [180]. Monochromated X-ray Photoelectron Spectroscopy (MXPS) measurements showed the attachment of the thiol sulfur headgroup onto the cluster surface leading to a positive BE shift in the Au 4f corelevel. No line width broadening could be observed indicating that the thiol-gold interaction affects the whole... 

Powder X-ray dififiaction patterns were recorded using Cu Ka (1.5418 A) radiation on a Philips 1050/81 vertical goniometer, fitted with a diffracted beam graphite monochromator. X-ray photoelectron experiments were carried out in a Escalab 200R (Fisons Instrumrats) using monochromatic A1 Ka radiation and operating at 10" Torr base pressure. Transmission electron microscopy analysis was performed in a JEOL lOOCX either by direct observation or after extractive replication of samples (support dissolution).
