Nondestructive Evaluation of Zirconium Phosphate Bonded Silicon Nitride Radomes
… toughness, and thermal shock capabilities. Zirconium phosphate bonded silicon nitride (Zr-PBSN), which has a low and thermally stable dielectric constant, high rain erosion resistance and a low-cost processing method, has been developed for radome applications in advanced tactical missiles. …

Ion-exchange studies of yttrium doped zirconium phosphates for use in the remediation of nuclear waste
… in the ion-exchange properties of layered zirconium phosphates. This interest has been renewed due to potential applications in the remediation of nuclear waste. They are believed to be preferred to the conventional ion-exchange materials due to their increased stability under acid …

CMZP and Mg-doped Al2TiO5 Thin film Coatings for High Temperature Corrosion Protection of Si3N4 Heat Exchangers
… crack-free oxide coatings of calcium magnesium zirconium phosphate (CMZP) and magnesium doped aluminum titanate (Mg-doped Al2TiO5) were successfully deposited on Si3N4 using the sol-gel and dip-coating technique. Coated and uncoated samples were then exposed to a sodium containing atmosphere at …

Doped Layered Phosphate Catalysts for the Activation of Glycerol
… area was carried out by Aresta et al. in which γ-zirconium phosphate was used to catalyse the reaction between glycerol and urea to form glycerol carbonate. It is thought that the reaction proceeds via a two-step reaction. Firstly the glycerol and urea react forming glycerol carbamate, this …

Bacterial acid phosphatase and its application to waste remediation and metal recovery
… of metal ions the phosphatase produces metal phosphate at the cell surface via the liberation of inorganic phosphate from a phosphate donor (glycerol-2-phosphate). Previous studies using biogenic hydrogen uranyl phosphate (HUP) on Serratia sp. removed \(^{60}\)Co, \(^{137}\)Cs and \(^{90}\)Sr …

Microwave assisted remediation of organic waste in aqueous effluent streams
… the recovery of radioisotopes using 30% tributyl phosphate in odourless kerosene, the organic phase is degraded due to the effects of radiolysis. This results in a very complex mixture with dibutyl phosphate, monobutyl phosphate and phosphoric acid amongst its components; the odourless kerosene is …

Polymeric and Polymer/Inorganic Composite Membranes for Proton Exchange Membrane Fuel Cells
… ether sulfone)s copolymers doped with zirconium phosphates and phenyl phosphonates were synthesized and showed a significant reduction in methanol permeability. These copolymer/inorganic nanocomposite hybrid membranes show lower water uptake and conductivity than Nafion and neat …
