Ultrasound (US) treatment coupled with membrane filtration has been utilized for membrane fouling control in water treatment; however, large-scale implementation of ultrasonic cleaning equipment appeared to be cost-prohibitive. In this study, a porou

Z-type hexaferrites are considered for applications in the 10 MHz to 1 GHz band due to their potential to overcome Snoek's limit. However, state-of-art hexaferrites have high magnetic loss, related to substantial micro-structural inhomogeneity and pr

Simple, fast, and cost-effective defect abatement of inorganic gas separation membranes can be achieved by application of a continuous polymer layer. This polymer diminishes defect flow and is stable at a wide range of operating conditions. In the st

Dense, high-purity TiO2 was prepared from commercially available powders. These powders were deagglomerated, colloidally stabilized in aqueous NH3, followed by screening to remove residual agglomerates. Homogeneous compacts were formed using colloida

The growth of zeolite membranes with controlled thicknesses in the sub-micron to micron region is examined, using zeolite L as the example. It was demonstrated that by controlling the concentration of the zeolite solid load and suspension viscosity,

The structures of Li 2 M O 3 ( M =Ir, Pt) can be derived from the well-known Li-ion battery cathode material, LiCoO 2 , through ordering of Li + and M 4+ ions in the layers that are exclusively occupied by cobalt in LiCoO 2 . The additional cation or

Nanostructured ZrO2 coatings are prepared on both dense and porous substrates by wet-chemical deposition of non-agglomerated 5 nm precursor particle dispersions, followed by thermal processing. The precursor particle dispersions are made by modified

Continuous, thin, oriented zeolite A membranes are produced by a two-step synthesis on macroporous α-Al 2 O 3 supports. In the first step, zeolite A nano-cubes with ∼350-nm edges are prepared as a native impurity phase in zeolite Y synthesis dispe
