ABSTRACTThere is a need in the semiconductor industry to develop new techniques and instrumentation for the elemental and chemical analysis of submicron, particularly <0.2 μm, particles. The development of these techniques and instrumentation could be assisted by submicron particle reference standards. We propose that high number-density, noble metal (Cu, Ag, Au) particles on silicon, with controlled diameters in the range of 0.02 μm to 0.10 μm, be developed and used as particle reference standards.

A route to synthesize porous materials with a bimodal macro/mesoscopic pore system has been investigated in this work. Polystyrene with sub-micrometer size was used as a template in the synthesis. The resulting mesoporous silica wall replicated inversely the morphology of polystyrene template and had highly ordered three-dimensional arrays of macro pores. Large and moldable meso/macro porous silica monoliths could be obtained in centimeter scale by using monodispersed polystyrene beads and MCM-41 sol solutions. These bimodal structured porous silicates have been used as supports for asymmetric kinetic resolution of racemic epoxides to synthesize optically pure epoxide.
