It is still a great challenge to prepare high performance mixed matrix membranes (MMMs) because of the difficulty in finely tuning the compatibility between filler and organic phases. In this work, ZIF-8 nanoparticles hydrophobically functionalized by 5, 6-dimethylbenzimidazole (DMBIM) via shell ligand exchange (SLE) reaction were incorporated into polydimethylsiloxane (PDMS) matrix to fabricat...
Pervaporative desalination is an efficacious method to obtain fresh water from saline sources. High salt rejection and capacity cope with high-salt concentration solutions are important advantages of pervaporation process. To improve pervaporative performance, researches concentrate on novel membrane types. Water stable metal organic frameworks loaded membranes attract substantial attention amo...
Abstract The most promising approaches to making polysiloxane-based membranes more selective are considered. These can be subdivided into three groups: (1) development of new membrane materials by copolymerization, (2) modification the polysiloxane chain (in backbone and pendant chains), (3) mixed matrix membranes. All subjected a critical analysis, conclusions made on prospects for high-select...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
