| 20090326255 | METHOD FOR MAKING ALKOXY-MODIFIED SILSESQUIOXANES AND AMINO ALKOXY-MODIFIED SILSESQUIOXANES - A method is presented for making an amino alkoxy-modified silsesquioxane (amino AMS) comprising one or more compounds selected from the group consisting of an amino-AMS, an amino/mercaptan co-AMS, an amino/blocked mercaptan co-AMS, and mixtures of these. The use of solid strong cationic catalysts in this reaction system is advantageous because the catalyst remains as a solid throughout the reaction, allowing simplified separation of the solid catalyst from the soluble amino AMS or amino co-AMS products, resulting in total or near total recovery of the amino AMS or amino co-AMS products, as well as virtual total recovery of the catalyst for recycling. The use of the solid strong cationic catalysts is advantageous because it results in amino AMS products that are free of, or substantially free of, residual acid catalyst. | 12-31-2009 |
| 20100168457 | MONOLITHIC ELECTROKINETIC PUMP FABRICATION - High-pressure electrokinetic (“EK”) pumps comprising a hybrid monolith provide a high surface charge density and a continuous stable skeleton morphology with micrometer- sized through-pores. The hybrid monolith of the subject invention has superior mechanical strength and better stability in comparison to prior art monoliths with equivalent mechanical stability. The surface charge of the hybrid monolith can be modified and/or made stable by the use of different chemical reagents. The chemical reagents and resulting modification to the monolith serves to expand the usefulness of the hybrid monolith to a variety of pumping applications including chip-based systems and other applications where the ability to pump an acidic solution is required. | 07-01-2010 |

| 20130158281 | Non-precious Metal-based Hyrdosilylation Catalysts Exhibiting Improved Selectivity - Disclosed herein is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems. | 06-20-2013 |
| 20130317244 | ORGANIC-INORGANIC HYBRID CHIRAL SORBENT AND PROCESS FOR THE PREPARATION THEREOF - The present invention provides an organic-inorganic hybrid chiral sorbent for chiral resolution of various racemic compounds viz. racemic mandelic acid, 2-phenyl propionic acid, diethyl tartrate, 2,2′-dihydroxy-1,1′-binaphthalene (BINOL) and cyano chromene oxide with excellent chiral separation (enantiomeric excess, 99%) in case of mandelic acid under medium pressure column chromatography. These optically pure enantiomers find applications as intermediates in pharmaceutical industries. | 11-28-2013 |
