In this report, CeO2 nanorods and SiO2 nanospheres were mixed in various ratios and 10 wt% CuO was then impregnated onto these CeO2-SiO2 composite supports using a thermal decomposition method to prepare supported catalysts. In these composites suppo

The distribution of copper species (on the surface or in the bulk of CeO2 support) and the interfacial interactions between CuO and CeO2 are critical in understanding the synergistic effect on the catalytic activity of CeO2 supported CuO catalysts. I

The decomposition of cobaltocene under low energy electron irradiation appears facile, and evidence suggests that the decomposition products lead to an increase in the carrier concentration in semiconducting boron carbides. Using cobaltocene to intro

A boron carbide diode detector, fabricated from two different polytypes of semiconducting boron carbide, will detect neutrons in reasonable agreement with theory. Small deviations from the model calculations occur due to the detection efficiencies of

We fi nd evidence for a gradual change in the electronic properties of spin coated poly(3-hexylthio-phene) thin fi lms with temperature. The conduction properties appears to be mediated by hopping conduction dominated by a low density of defects st
