Precision Drug Delivery In article number 2206989, Yu Tao, Mingqiang Li, Xuesi Chen, and co-workers report a membrane-fusogenic liposome to precisely convey two glycan-engineering drugs onto the cell membrane into cytoplasm for physical modification of natural-killer-cell-activating glycans biological inhibition immunosuppressing glycans, respectively, thus sufficiently arousing natural killer ...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...

A high flux thin-film nanocomposite membrane epoxy/ zeolite NaA nanocomposite films prepared by using ultrasonic mixing and spin coating. The synthesized nanocomposites film was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravity analysis (TGA), and FTIR spectroscopy. Water softener and water flux characteristics of the epoxy/ zeolite NaA nanocomposite ...

In membrane processes, various agents are used to enhance, protect, and recover membrane performance. Applying these agents in membrane modification could potentially be considered as a simple method to improve membrane performance without additional process. Citric acid (CI) and sodium bisulfite (SB) are two chemicals that are widely used in membrane feed water pretreatment and cleaning proces...

In the present work, B-ZSM-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. The TiO2- Bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. The uniform membrane intermediate layers with low permeation resistance were...

In this research, modification on the ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentrations of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (...

The reported work is on the preparation and characterization of polyvinyl alcohol -g- Polyacrylic acid (PVA-g-PAA)/ Polybenzimidazole sulfone (PBIs) cation exchange membrane used for the electro dialysis of sodium chloride solution. The polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. The polymer ...

Membrane technology is important in industrial wastewater and water treatment. Recently, the polymeric membrane widely chosen these applications. However, they are lowtemperature ranges, low corrosion resistance, lifespan. Thus, researchers actively trying to develop a better such as natural clay ceramic due their excellent chemical, mechanical thermal high-pressure application long This detail...
