series (11) will present the synthesis chemistry of silica sols Silica-based microporous membranes can be successfully proto make unsupported membranes with predictable pore size/ cessed by sol–gel techniques. However tailor making of such memporosity. This article aims to give a detailed account of small branes is still not possible because of the unavailability of systemangle X-ray scattering...

We present the preparation and the characterization of the solution behavior and functional properties of superparamagnetic and/or fluorescent, thermo-responsive inorganic/organic hybrid particles with an intermediate protective silica shell and a smart polymer corona. These well-defined multifunctional nanogels were prepared via two consecutive encapsulation processes of superparamagnetic Fe(2...

A research has been carried out to develop natural rubber (NR) hybrid composites reinforced with marble sludge (MS)/Silica and MS/rice husk derived silica (RHS). The primary aim of this development is to scrutinize the cure characteristics, mechanical and swelling properties of such hybrid composite. The use of both industrial and agricultural waste such as marble sludge and rice husk derived s...

The main objective of the current review is to cover the overview of silica lipid hybrid microparticles. Lipid-based delivery systems recognized as a potential strategy for improving the oral absorption. Clinical applications of many lipid-based formulations are limited by the lack of clear guidelines of incomplete understanding of absorption mechanism and in vitro, in vivo formulation performa...

Background & Aims of the Study:  Recently membranes have been widely used in Mena region especially Iran,  due to purify the brackish water and solved the water scarcity  .Qom province is located in desert like area of Iran and faced to water shortage .The aim of this study is evaluation of the best method of membrane process in the ground water wells of Qom province, Iran, in 2016. Materials ...

In this work, two types of silica functionalized monosodium glutamate (GMSG and VMSG)/poly(vinyl alcohol) (PVA) were cross-linked by sol–gel process to prepare novel hybrid cation exchange membranes. The prepared membranes systematically characterized FTIR spectroscopy, SEM analysis, ion capacity (IEC), TGA, water uptake, swelling, mechanical strength diffusion dialysis performance for alkali s...

Palladium doped silica membranes were synthesized by the sol-gel method using two different procedures. The first palladium-doped silica membrane (M1) was synthesized with a coating of four layers of silica-palladium sol. The second membrane (M2) was synthesized with a coating of two silica layers followed by a coating of two silica-palladium layers. Scanning electron microscopy (SEM) proved th...

integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical co2 as a nonsolvent for the polymer solution. in present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. it is shown that the presence of silica nanoparticles not only di...
