Abstract

We present studies on the structure and chemical states of a catalyst developed by immobilizing palladium on S-terminated GaAs(001). Hard x-ray photoelectron spectroscopy (HX-PES) of core-level and valence band photoemission consistently indicates that the organopalladium molecules are reduced on the surface yielding Pd nanoparticles with a metallic nature. This finding is supported by high-resolution observations using scanning electron microscopy and backscattered electron image. HX-PES results also reveal that a portion of S atoms forming the S-termination is oxidized during the formation of Pd nanoparticles.

13. Thermally Stimulated Currents in Cured Resin of Electrostatic Powder Coating

Author

Ogiwara, T. and Ikezaki, K.

Subjects

Abstract

Thermally stimulated currents (TSC) were observed for commercial powder paints partially cured at different temperatures and different times. A higher temperature band between the two TSC bands observed in the cured paints shifted with regularity towards the high temperature side, depending on the cure temperature and time. Activation energies for the cure processes were derived from phenomenological analysis of this TSC peak shift on the basis of a simple model.

We present studies on the structure and chemical states of a catalyst developed by immobilizing palladium on S-terminated GaAs(001). Hard x-ray photoelectron spectroscopy (HX-PES) of core-level and valence band photoemission consistently indicates that the organopalladium molecules are reduced on the surface yielding Pd nanoparticles with a metallic nature. This finding is supported by high-resolution observations using scanning electron microscopy and backscattered electron image. HX-PES results also reveal that a portion of S atoms forming the S-termination is oxidized during the formation of Pd nanoparticles., journal article
