The negatively charged polyamide thin-film-composite nanofiltration membranes have been used to possibly treat the sodium-enriched water, particularly cooling tower water, to separate hardness producing solute like MgSO4 from univalent salts using ESNA and EDA nanofiltration membranes. The flux decl

Amorphous alloy membranes are anticipated as substitutes for expensive palladium membranes. Hydrogen separation modules consisting of four amorphous Zr36Ni64 membranes have been developed to demonstrate their practical usefulness. First, surface investigation showed that 50-mm-wide membranes are smo

Supported-liquid membranes using four kinds of triethylene glycol (TEG) liquids were used for the VOC vapor removal from air. The supported-liquid membrane was a double-layer type, in which a liquid membrane was placed on a hydrophobic microporous membrane. This construction enabled the vacuum mode

Cyclohexane is recognized to be one of the promising hydrogen storage materials but it is pointed out that its freezing point (ca. 6.5 C) is too high to use in the cold district. In this study, therefore, the mixtures of cyclohexane with methylcyclohexane as a hybrid chemical hydride were proposed

The boehmite-sol-coated membrane was prepared for using the water-repellent characteristics of -AlOOH. The stable boehmite sol was prepared in advance of the coating on the porous membrane surface; the preferred molar ratios of i-PrOH, EAcAc, and H2O to Al(O-sec-Bu)3 for the stable boehmite sol were

The characterization and gas transport properties (i.e., permeability, diffusivity, and solubility) of poly(lactic acid) (PLA) blend membranes were systematically investigated. PLA blends had a glass transition temperature of 60 C, a crystallization temperature of 116 C, and a melting temperature

Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) is a potential material for tissue engineering applications because of its excellent biodegradable and biocompatible properties. The aim of this study is to present a close picture of the interaction between human mesenchymal stem cells (hMSCs)

A series of thermo-responsive hydrogels were synthesized from N-isopropylacrylamide (NIPAAm), glycidyl methacrylate (GMA), and N, N-dimethyl acrylamide (DMA). The effect of the different monomer ratios of GMA/DMA in the copolymeric hydrogel on the swelling behaviors, physical properties, and drug re

Microporous foams of polymer blends of two biodegradable polyesters, poly(L-lactic acid) (PLLA) and poly("-caprolactone) (PCL), were prepared via thermally induced phase separation method. The phase behaviors of the solutions of the polymer blends in 1,4-dioxane containing water were similar, which

their higher mechanical strength, hydrophilicity, and better cell compatibility, are promising biomaterials for tissue engineering applications. Fig. 7. The proliferation of GF cells on the surfaces of TCPS, CH/CS (90/10) and CH (100/0) (n ¼ 4, mean+S.D.). By using the freeze-gelation method, we suc
