It was shown that germane high purification is possible up to sufficient for microelectronics water impurity level equaled < 0.1 ppm (< 10– %).

The possibility of high-purity fluorocarbon production was shown. The experimental results show that further investigation of the high purification is perspective and needed for getting fluorocarbons with purity no less than 99.999%.

A set of different membranes from 6FDA6F, cast from different solvents, have been obtained and their gas permeability properties have been tested. Assuming that fractal dimension measures how the material fills a volume rather than a plane on the membrane surface, an increase in this parameter might

A mixed matrix membrane structure which can be cast as permselective gas separation membranes with attractive gas separation performances could be obtained with polycarbonate as matrix and zeolite 4A as filler.

Fig. 1. SEM image of before Cu-reflow. Pd–Cu–Ni ternary alloyed dense film was deposited on the porous nickel support using sputtering improved by copper reflow technique. Cupper reflow was good enough technique to remove the defects and delamination on the membrane surface. A Pd–Cu–Ni ternary alloy

This kind of porous nickel support has very small uniform pore size of 33 nm comparing to commercial porous ceramic and stainless steel substrate. Therefore, porous nickel support can be offered as new support material for palladium and palladium-base alloyed composite membrane.

CSLM has been used together with macroscopic results to characterize foulant removal from microfiltration membranes. The effect of running PBS buffer during 30 min (after the filtration) is that protein is driven inside the membrane and the PBS flux is lower that the one obtained at the end of the p
