Porous membrane

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

Poly(vinylidene fluoride) (PVDF), polymethyl methacrylate (PMMA) and cellulose acetate (CA) in the presence of N-methyl pyrrolidone were blended in various combinations by using dimethylformamide (DMF) and glacial acetic acid (CH3COOH) as solvent and used to prepare flat-sheet membranes by the phase

Electrophoretic separations were theoretically performed for large polyelectrolytes such as DNA in the membrane chromatography. This paper deals with the study of the mass transfer involved in multi-layered membrane chromatography in the presence of an electric field. The different contributions to

Soft-chemistry routes were used to synthesize Ce0.9Gd0.1O1.95 (CGO) membrane materials with attractive structural, morphological and textural properties. In the intermediate temperature domain between 500°C and 700°C, the average crystallite size is in the range 8–22 nm and the specific surface area
