Microstructures in phase inversion membranes . Part 2 .
Membranes were prepared from a castmg solution of a water-soluble polymer, poly (vmyl pyrrohdone) (PVP), and a membrane forming polymer, poly (ether sulfone), m l-methyl-2-pyrrohdone (NMP) as solvent by immersing them m mixtures of water and NMP It was found that the addltlon of PVP to the ternary system suppresses the formatlon of macrovolds m the sub-layer, while the ultraflltratlon-type top-...
متن کاملPorosity estimation using post-stack seismic inversion method in part of the Qom Formation in the Aran Anticline, Central Iran
Petro-physical parameters of the reservoir (porosity, permeability, water saturation) are the most important parameters of oil and gas reservoirs. Economic appraisals of oil and gas reservoirs, as well as management and planning for the production and development of these reservoirs are not possible without the estimation of petro-physical parameters. Since measurements of these parameters are ...
متن کاملTextural Evolution and Phase Transformation in Titania Membranes: Part 1 .-Unsupported Membranes
Textural evolution in sol-gel derived nanostructured unsupported titania membranes has been studied using differential scanning calorimetry (DSC), differential thermal analysis (DTA), thermal gravimetry (TG), X-ray diffraction (XRD) and N, adsorption. The anatase-to-rutile phase transformation kinetics were studied using the Avrami model. The precursor gel had a surface area of ca. 165 m2 g-', ...
متن کاملBuckled Membranes for Microstructures
Based on energy variation methods we calculated the deflection of membranes under the combined load of an external pressure and an internal lateral stress. A lateral load gives rise to buckling once a critical load is exceeded. The combination of transversal loads and lateral loads changes the properties of the membrane (and other structures) in the vicinity of the buckling load: The membrane d...
