Porous nanocomposites in the Al2O3-ZrO2 system were studied with a view to understand the selection rules for developing high temperature stable porous oxide systems. The results were also compared with TiO2-Al2O3 nanocomposite systems. The pore stru

The permeation of a series of gases with widely different Lennard-Jones kinetic diameters and sorption properties is investigated as a function of feed pressure (up to 100 kPa) and temperature (298-473 K) with two different methods. The membrane syst

Thin (2-7 μm) polycrystalline randomly-oriented zeolite MFI membranes were prepared on an α-Al2O3 support by one or more subsequent hydrothermal treatments. Different particle sizes (275-700 nm) in the layer were achieved by changing the synthesis

The friction and wear behaviour of two ZrO2-Al2O3 composite materials, ADZ (20 wt% Al2O3 dispersed in yttria-doped ZrO2 matrix) and ZTA (Al2O3-15 wt% ZrO2), were investigated. Sliding wear tests were carried out on these materials under dry condition

Polycrystalline randomly oriented defect free zeolite layers on porous α-Al2O3 supports are prepared with a thickness of less than 5 μm by in situ crystallisation of silicalite-1. The flux of alkanes is a function of the sorption and intracrystalli

A zirconia-yttria gel, made by coprecipitation, was treated in six different ways to obtain a nanocrystalline Y-TZP powder: one large gel batch was split into six parts of which one was crystallized in air and the others crystallized either in water

Sorption experiments with H2, CO2, CH4 and iso-C4H10 were performed on microporous SiO2 and SiO2/TiO2 (30 mol% TiO2) non-supported membrane top-layers using volumetric and gravimetric techniques. For silica, the sorption capacity decreases in the ord

Yttria-stabilized cubic zirconia (YSZ)-palladium dual phase composites have been investigated. The percolative composite containing 40 vol% Pd (ZYPd40) showed a much larger oxygen permeability than that of the non-percolative composite containing 30
