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

The gas transport properties of Polyimide membranes were examined as a function of physical aging time. A clear decrease of the gas permeability coefficient was observed. Interpretation of the permeation properties using results from differential scanning calorimeter and dynamic mechanical analyzer

Short- and long-term physical aging tests of high molecular weight poly(methyl methacrylate) (PMMA) membranes have been performed at different temperature. The effects of physical aging on the gas permeation properties are studied. Experimental data show that the physical aging decreases the volume

Polytetrafluoroethylene (PTFE) is a remarkable membrane material. Due to its high melting point, PTFE fine powder cannot be processed using the conventional melting processing methods. Instead, techniques such as paste extrusion, rolling and sintering have to be employed. In this paper, a PID contro

Ethanol/water mixture is separated by pervaporation through a polysulfone (PSf) membrane filled with zeolite. The coupling agent effect of 3-aminopropyltrimethoxysilane (APTMS) on the preparation of PSf/zeolite membrane was also studied. APTMS enhanced the contact of zeolite particles with PSf chain

RGDS was successfully immobilized on the PLLA scaffolds via plasma treatment. It was observed that the immobilized RGDS promoted attachment of ROS cells to PLLA. Also, more cells were found in the RGDS-modified scaffold than in the unmodified scaffold, tending to form mineralized foci. The results s

In the present work, cell-specific peptides were immobilized on chitosan and PLA scaffolds. The amount of immobilization, determined by HPLC, was confirmed to be in the effective range. Results from cultures of human fetal skin fibroblasts, rat osteosarcoma, and periodontal fibroblasts demonstrated

The pervaporation performances of a series of functionalized syndiotactic poly(styrene-co-4-methylstyrene) (SPSM) membranes for various alcohol mixtures were investigated. The effect of functionalization on the thermal properties and polymer structure of the SPSM membranes were also investigated. Th
