asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Among the various film preparation methods, electroplating is one of simplest and most economical methods. However, it challenging to collect a dense single Pd through plating, owing accumulation stress in during process. Therefore, characteristics plated have not been clearly identified, although pure widely used metallic-hydrogen-purification membranes. In this study, concentration was reduce...
This study examined the morphologic features of the parietal peritoneal membranes of 130 patients undergoing peritoneal dialysis (PD) and compared them with the features of the peritoneal membranes of normal individuals, uremic predialysis patients, and patients undergoing hemodialysis. The median thickness of the submesothelial compact collagenous zone was 50 microm for normal subjects, 140 mi...
The 2-amino-3-benzoylthiophene PD 81,723 has been shown to exhibit allosteric enhancement of adenosine A1 receptor binding and function. The aim of this study was to clarify the mechanism of this effect using membranes purified from rat brain and Chinese hamster ovary (CHO)-A1 cells that stably express the rat adenosine A1 receptor as well as intact CHO-A1 and nontransfected CHO cells. In membr...
a palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-pss). hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674k and the pressure difference of two sides of membrane up to 90kpa. a simplified resistance model was employed to analyze the permeation behavior of hydrogen through pd/ox-...
