Recent advances and avenues for further research and development in three specific fields of membrane science and technology
are reviewed. The potential of membrane processes for gas separation has been considerably improved by the development of
new materials combining high permeability and selectivity. While working correlations between polymer structure and permeation
characteristics have been evolved, there is need to further develop our basic understanding of this relationship. The second
field reviewed is that of improving the separation characteristics of porous membrane filtration (ultra-/microfiltration).
Recent promising approaches include the fabrication of membranes with uniform porosities, new module configurations and the
manipulation of feed chemistries. The third area highlighted is that of hybrid membrane processes. These are considered both
as integrated processes in which the membrane process operates in conjunction with another unit operation or as a coupled
transport process in which the basic functioning of the membrane is intimately coupled with another physical or chemical process
in single unit operation. The scope for basic research in these fields is indicated. 相似文献

Euromembrane 2000 was held in Israel on 24–27 September 2000. In keeping with the conference's tradition, it brought together people working in different areas of membranology, and it covered both research & development and applications. Based entirely on abstracts of papers which were presented at the conference, this thematic round-up focuses on a number of the talks which dealt solely with developments in liquid membranes, their characteristics and properties, and membrane distillation. 相似文献
