20090032463 | COMPOSITE MATERIALS COMPRISING SUPPORTED POROUS GELS - This invention relates to a composite material that comprises a support member that has a plurality of pores extending through the support member and, located in the pores of the support member, and filling the pores of the support member, a macroporous cross-linked gel. The invention also relates to a process for preparing the composite material described above, and to its use. The composite material is suitable, for example, for separation of substances, for example by filtration or adsorption, including chromatography, for use as a support in synthesis or for use as a support for cell growth. | 02-05-2009 |

20150376041 | AQUEOUS SYSTEMS HAVING LOW LEVELS OF CALCIUM CONTAINING COMPONENTS - Hydroxycarboxylic acids and/or transition metal salts may be added to an aqueous system to inhibit corrosion and/or scale deposition within the aqueous system. The aqueous system may include a calcium containing component in an amount ranging from about 0.01 ppm to about 200 ppm. The hydroxycarboxylic acid may have two or more carboxylic acid groups. The transition metal salt may have or include a transition metal, such as but not limited to, Zn (II), Zn (IV), Sn, Al, Mn, Mo, and combinations thereof. The aqueous system may be or include a cooling tower, a cooling water system, and combinations thereof. | 12-31-2015 |
20150376799 | NON-PHOSPHOROUS CONTAINING CORROSION INHIBITORS FOR AQUEOUS SYSTEMS - Hydroxycarboxylic acids and/or transition metal salts may be added to an aqueous system to inhibit corrosion and/or scale deposition within the aqueous system. In a non-limiting embodiment, a phosphorous-containing component may not be added to or include in the aqueous system. The hydroxycarboxylic acid may have two or more carboxylic acid groups. The transition metal salt may have or include a transition metal, such as but not limited to, Zn (II), Zn (IV), Sn, Al, Mn, and combinations thereof. The aqueous system may be or include a cooling tower, a cooling water system, and combinations thereof. | 12-31-2015 |
