    摘要: The present invention sorts microorganism populations from a mixture which contains more than one microorganism population. Microorganisms of different types vary in size, shape, and surface charge characteristics. These characteristics we believe contribute to the rate of migration for microorganisms under the influence of an electric field. Microorganisms of the same population (genus and species) will migrate similarly. By applying an electric field in a direction opposite the direction of fluid flow, separation is enhanced.

    摘要: Group Transfer Polymerization (GTP) process for preparing a "living" polymer, the process comprising contacting under polymerizing conditions in a polymerization medium, at least one acrylic or maleimide monomer with an initiator which is a tetracoordinate organosilicon, organotin or organogermanium compound having at least one GTP initiating site and a catalyst which is or is a source of an anion selected from the group consisting of bifluoride, fluoride, cyanide, azide or a selected oxyanion, or a selected Lewis acid or Lewis base, the process further characterized in that the initiator or the anion or Lewis acid catalyst is chemically attached (grafted) to a solid support that is insoluble in the polymerization medium.
