Patent number: 7151146Abstract: The present invention relates to a method for preparing neodymium-carbon-nanotube and a process for preparing 1,4-cis-polybutadiene utilizing the same and more particularly, neodymium-carbon-nanotube. Neodymium is introduced by coordination with carboxylic acid, which is formed on the surface of carbon nanotube. In 1,3-butadiene polymerization with the neodymium-catalyst comprising the neodymium-carbon nanotube, a particular halogen compound, and a particular organometallic compound in an appropriate ratio, high 1,4-cis polybutadiene having molecular weight of 10,000 to 2,000,000 is produced, which exhibits excellent mechanical properties such as elasticity and durability.Type: GrantFiled: December 23, 2005Date of Patent: December 19, 2006Assignee: Korea Kumho Petrochemical Co., Ltd.Inventors: Gwanghoon Kwag, Pilsung Kim, Shin Han, Hyung Kyu Choi, Dong Hwan Kim, Seung Hwa Lee, Sung Hoon Han

Patent number: 7125965Abstract: The invention provides methods and compositions for molecular resonance imaging of membrane potential. The compositions comprise an indicator moiety attached through an optional linker to a macrocycle component that binds a lanthanide. The indicator moiety changes conformation in response to alterations in membrane potential and alters the interaction of the bound lanthanide with water. This alteration produces a detectable change in MRI signal , notably the T1 value. A preferred indicator moiety is spiropyran as it exhibits membrane-potential driven interconversions between the closed-ring spiropyran conformer and the extended merocyanine conformer. A preferred macrocycle is DO3A, known to bind gadolinium and an established MRI contrast agent. The methods of the invention comprise in vivo and in vitro uses of compositions of the invention to obtain MRI images that provide information about membrane potential.Type: GrantFiled: November 3, 2003Date of Patent: October 24, 2006Assignee: The Regents of the University of CaliforniaInventor: Angelique Louie

Patent number: 7012140Abstract: The present invention is directed, in general, to a contrast agent comprising a tetraazacyclododecane ligand and comprising a macrocyclic ring and a paramagnetic metal ion coordinated to the tetraazacyclododecane ligand. Pendent arms R, R?, R? and R?? attached to a ring nitrogen. The pendent arms have the general formula: ?C?HR1R2 and for three or more of the pendant arms a chirality of the carbon atoms C? are identical for each of three or more of the pendant arms. The R1 group is larger than hydrogen and R2 is selected from the group consisting of: an alcohol, amides, a carboxylate, phosphinates and a phosphonate. One or more substituents R6 is a group larger than a methyl group and is located on one or more ring carbons.Type: GrantFiled: July 14, 2003Date of Patent: March 14, 2006Assignees: Board of Regents, The University of Texas System, MacrocyclicsInventors: A.
