      abstract     = {Hybrid organosilica membranes have great potential for
                      realizing high-flux, high-selectivity gas separation and
                      pervaporation. Current membranes, however, have one major
                      problem: the intermediate layers between the selective layer
                      and the porous support are made of unstable γ-alumina. In
                      this article, a strongly improved membrane set-up based on
                      mesoporous stabilized zirconia (8YSZ) intermediate layers is
                      reported. This novel membrane showed selectivities in the
                      range of 20–30 for different CO2/N2 mixtures and
                      accompanying CO2 permeances of 1.5–4 m3/(m2.h.bar). In
                      pervaporation tests with water/isopropanol and water/butanol
                      mixtures (5 $wt\%$ water), the membrane selectively
                      separated water (separation factor ~150 – 600) and an
                      excellent flux of ~5 kg m-2h−1 was achieved at 70 °C.
                      These results represent an important step towards the
                      industrial application of hybrid silica membranes in
                      applications such as pervaporation as well as the selective
                      removal of CO2. The analysis also shows for the first time
                      that effective gas separation and pervaporation is realized
                      when γ-alumina is substituted for another, more stable
                      membrane material.},
