Polymer Aluminophosphate Mixed Matrix Membranes for Gas Separations
… effects on transport when a microporous layered aluminophosphate was added to a polymer matrix. The clay like layered aluminophosphate used contains sheets with 8MR ring openings in the size range of 3-4 Ã . The molecular level dispersion of this material into a polymer matrix is theorized to …

Exploitation of synergy in oxidation catalysis with bimetallic aluminophosphate catalysts
A series of novel bimetallic aluminophosphate catalysts were prepared with the simultaneous isomorphous substitution of cobalt (III) and manganese (III) for aluminium (III) and titanium (IV) replacing phosphorus (V). By substituting simultaneously for both Al (III) and P (V) in the ordered …

On the Structure and Dynamics of Aluminophosphate Glass-forming Melts measured by Dynamic Light Scattering
… of dynamic light scattering studies of molten aluminophosphate liquids, [Al(PO3)3]x[NaPO3]100-x, obtained by photon correlation spectroscopy. The study covers a range of compositions designed to manipulate the network connectivity of the glass-forming liquid in order to investigate how the …

Aromatization of n-hexane by platinum containing molecular sieves and distribution and motion of organic guest molecules in zeolites
… NaY, CsNaY, FAU, EMT, ZSM-12 and SSZ-24) and aluminophosphate (AIP0₄-5 and VPI-5) molecular sieves. ¹³C MAS NMR, TEM and H₂ chemisorption measurements reveal that Pt can be loaded into the micropores of molecular sieves with both charged and neutral frameworks. Pt containing molecular sieves …

Photon correlation spectroscopy study of slow relaxation in alkali germanate and phosphate germanate glass melts
… with sodium phosphate, then extending to sodium aluminophosphate, sodium borate, and sodium germanate glass melts. These studies revealed a compelling and consistent picture: the fragility of a network-forming glass melt is governed primarilyby the average bridging oxygen bond density of the …

Phosphate-doped borosilicate enamel coating used to protect reinforcing steel from corrosion
… due to the formation of aluminophosphate species that increases the connectivity of phosphate sites to the borosilicate glass network. The addition of P<sub>2</sub>O<sub>5</sub> has an insignificant effect on thermal properties like T<sub>g</sub>, T<sub>s</sub> and CTE, …

Element substituted aluminophosphates
… by hydrothermal crystallization of typical aluminophosphate gels with the adequate metal substrates at temperatures of 200°C, 150°C, and 150°C respectively. Samples of each material were calcined in oxidant, reducing and inert atmospheres and the properties of the treated solids studied by …

Development and characterisation of phosphate glasses for athermalisation
… properties. The properties of the potassium aluminophosphate glasses were strongly influenced by the strengthening effect of Al<sup>3+</sup>, the trend observed for the binary phosphate glasses depended on the availability of terminal oxygens to coordinate the cations while the change in the …

Fundamental research of the solvent role in the ionothermal synthesis of microporous materials
… the first time as the mineralizer to synthesize aluminophosphates in ILs and it could lead to both dense and porous materials. Regardless of the acid used, frameworks synthesized after several hours always undergo a dramatic change after further heating. A slightly longer alkyl chain of ILs could …
