    Mesoporous templated MCM-48 silica was prepared using a C16 surfactant as template. The MCM-48 powders and thin films were characterized by different techniques. Two types of porous supports were used, namely macroporous Âż-alumina and silicon microsieves. The supported MCM-48 layers were applied as liquid permeable membranes in pressure-driven nanofiltration and electric field-mediated ion transport experiments

    The Synthesis and Composition of Dual-Phase 3Y-TZP/RuO2 Electrode Powders

    This research was performed to learn more about the electron conducting yttria doped zirconia/ruthenia dual-phase system. The study indicated that for all starting powder precipitates (by either co-precipitation or sequential precipitation) strong separation between the Ru and Zr-species upon heating occurred already at the unexpected low temperature of 100–200°C. The solubility of RuO2 in 3Y-TZP (zirconia stabilised into a tetragonal phase by a 3 mol% Y2O3 addition) after calcination at 600°C was estimated at 3 mol%, independently of the used synthesis technique
