20090269236 | DUCTILE MAGNESIUM ALLOY - The present invention relates to a corrosion resistant magnesium alloy which can be prepared with a justifiable expenditure of energy from scrap or impure copper containing precursors and displays a ductility such that it can be used as a casting or kneading material. The magnesium alloy contains, relative to the total weight of the magnesium alloy, 1 to 9 wt. % aluminium, 0.6 to 6 wt. % zinc, 0.1 to 2 wt. % manganese, 0 to 2 wt. % rare earth elements, 0.5 to 2 wt. % copper, wherein the weight ratio of aluminium to zinc lies in the range from 1:1 to 2:1. | 10-29-2009 |
20090173694 | ISOPOROUS MEMBRANE AND METHOD OF PRODUCTION THEREOF - A membrane is produced by dissolving one or more polymers, at least one of which is a block copolymer, in a liquid which includes a solvent, to produce a casting solution. The casting solution is formed into film, and the film is immersed into a precipitation bath which contains at least one non-solvent for the block copolymer so that the film forms a membrane. The membrane is used for filtering a fluid that contains colloidal particles or proteins, and/or for ultrafiltration or nanofiltration, by flowing the fluid through the membrane. | 07-09-2009 |
