They can be used in various separation processes, especially those relating to hydrocarbons.Type: ApplicationFiled: June 11, 2009Publication date: July 14, 2011Applicants: Universite De Caen-Basse Normandie, Centre National De La Recherche Scientifique- CNRS-Inventors: Christian Serre, Alexandre Vimont, Philip Llewellyn, Jong-San Chang, Patricia Horcajada-Cortes, Gérard Ferey, Marco Daturi, Young-Kyu Hwang

Patent number: 7968487Abstract: Novel phosphine-free non-ionic single catalysts, and method for making such catalysts, for the homo-polymerization and copolymerization of olefins such as ethylene, ?-olefins and functionalized olefins without the use of additional co-activators, are disclosed. These phosphine-free non-ionic single catalysts are also active for co-polymerization of olefins with monomers with polar functionalities. The catalyst of this invention comprise of a late transition metal with a chelating monoanionic ligand, an R group and a neutral 2 electron donor ligand. Catalysts are prepared by the oxidative addition of benzylhalide (halide=Cl, Br or I) to an appropriate metal source in the presence of a stabilizing agent, such as nitrogen based ligands, followed by the addition of the deprotonated form of the chelating ligand.Type: GrantFiled: January 5, 2007Date of Patent: June 28, 2011Assignee: The Regents of the University of CaliforniaInventors: Guillermo C. Bazan, Rene' Rojas

Publication number: 20100284860Abstract: An article is provided for immobilizing functional organic biomolecules (e.g. proteins, DNA, and the like) through a covalent bond to a thiolate or disulfide monolayer to a metal surface wherein an extra activation step of the surface layer or an activation step of the functional biomolecules or bioreceptors could be avoided. The monolayer can contain, but is not limited to, two moieties. One has a group that resists nonspecific adsorption and another has a group that directly (without activation) reacts with functional groups on the biomolecules. In addition, poly(ethylene oxide) groups are incorporated in the monolayer surfaces to resist the nonspecific adsorption and to enhance the specific affinity interactions. A sensor device including these monolayers is also provided to perform reproducible, sensitive, specific and stable bioanalysis.Type: ApplicationFiled: July 22, 2010Publication date: November 11, 2010Applicant: IMECInventors: Filip Frederix, Kristien Bonroy, Karolien Jans

Publication number: 20100176031Abstract: Crystals of [VOBDC](H2BDC)0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.Type: ApplicationFiled: August 9, 2007Publication date: July 15, 2010Inventors: Allan J.
