Patent number: 7101643Abstract: New polymer electrolytes were prepared by in situ cross-linking of allyl functional polymers based on hydrosilation reaction using a multifunctional silane cross-linker and an organoplatinum catalyst. The new cross-linked electrolytes are insoluble in organic solvent and show much better mechanical strength. In addition, the processability of the polymer electrolyte is maintained since the casting is finished well before the gel formation.Type: GrantFiled: May 31, 2002Date of Patent: September 5, 2006Assignee: The Regents of the University of CaliforniaInventors: John Borland Kerr, Shanger Wang, Jun Hou, Steven Edward Sloop, Yong Bong Han, Gao Liu

Patent number: 6835952Abstract: The present invention comprises a new nanoscale metal-semiconductor, semiconductor-semiconductor, or metal-metal junction, designed by introducing topological or chemical defects in the atomic structure of the nanotube. Nanotubes comprising adjacent sections having differing electrical properties are described. These nanotubes can be constructed from combinations of carbon, boron, nitrogen and other elements. The nanotube can be designed having different indices on either side of a junction point in a continuous tube so that the electrical properties on either side of the junction vary in a useful fashion. For example, the inventive nanotube may be electrically conducting on one side of a junction and semiconducting on the other side. An example of a semiconductor-metal junction is a Schottky barrier. Alternatively, the nanotube may exhibit different semiconductor properties on either side of the junction.Type: GrantFiled: March 21, 2003Date of Patent: December 28, 2004Assignee: The Regents of the University of CaliforniaInventors: Vincent Henry Crespi, Marvin Lou Cohen, Steven Gwon Sheng Louie, Alexander Karlwalter Zettl

Patent number: 6647166Abstract: Thin films of transition metal compositions formed with magnesium that are metals, alloys, hydrides or mixtures of alloys, metals and/or hydrides exhibit reversible color changes on application of electric current or hydrogen. Thin films of these materials are suitable for optical switching elements, thin film displays, sun roofs, rear-view mirrors and architectural glass.Type: GrantFiled: July 9, 2001Date of Patent: November 11, 2003Assignee: The Regents of the University of CaliforniaInventor: Thomas J. Richardson

Patent number: 6534332Abstract: A dramatic reduction of the dislocation density in GaN was obtained by insertion of a single thin interlayer grown at an intermediate temperature (IT-IL) after the growth of an initial grown at high temperature. A description of the growth process is presented with characterization results aimed at understanding the mechanisms of reduction in dislocation density. A large percentage of the threading dislocations present in the first GaN epilayer are found to bend near the interlayer and do not propagate into the top layer which grows at higher temperature in a lateral growth mode. TEM studies show that the mechanisms of dislocation reduction are similar to those described for the epitaxial lateral overgrowth process, however a notable difference is the absence of coalescence boundaries.Type: GrantFiled: April 20, 2001Date of Patent: March 18, 2003Assignee: The Regents of the University of CaliforniaInventor: Edith D. Bourret-Courchesne

Patent number: 6440213Abstract: Disclosed is a process for making surfactant capped nanocrystals of transition metal oxides. The process comprises reacting a metal cupferron complex of the formula M Cup, wherein M is a transition metal, and Cup is a cupferron, with a coordinating surfactant, the reaction being conducted at a temperature ranging from about 250 to about 300 C., for a period of time sufficient to complete the reaction.Type: GrantFiled: October 30, 2000Date of Patent: August 27, 2002Assignee: The Regents of the University of CaliforniaInventors: A Paul Alivisatos, Joerg Rockenberger

Patent number: 6379472Abstract: The present invention comprises growing gallium nitride films in the presence of bismuth using MBE at temperatures of about 1000 K or less. The present invention further comprises the gallium nitride films fabricated using the inventive fabrication method. The inventive films may be doped with magnesium or other dopants. The gallium nitride films were grown on sapphire substrates using a hollow anode Constricted Glow Discharge nitrogen plasma source. When bismuth was used as a surfactant, two-dimensional gallium nitride crystal sizes ranging between 10 &mgr;m and 20 &mgr;m were observed. This is 20 to 40 times larger than crystal sizes observed when GaN films were grown under similar circumstances but without bismuth. It is thought that the observed increase in crystal size is due bismuth inducing an increased surface diffusion coefficient for gallium. The calculated value of 4.7×10−7 cm2/sec. reveals a virtual substrate temperature of 1258 K which is 260 degrees higher than the actual one.Type: GrantFiled: November 10, 2000Date of Patent: April 30, 2002Assignee: The Regents of the University of CaliforniaInventors: Christian K. Kisielowski, Michael Rubin

Patent number: 6316668Abstract: Carboxylic acids are sorbed from aqueous feedstocks onto a solid adsorbent in the presence of carbon dioxide under pressure. The acids are freed from the sorbent phase by a suitable regeneration method, one of which is treating them with an organic alkylamine solution thus forming an alkylamine-carboxylic acid complex which thermally decomposes to the desired carboxylic acid and the alkylamine.Type: GrantFiled: February 25, 1999Date of Patent: November 13, 2001Assignee: The Regents of the University of CaliforniaInventors: C. Judson King, Scott M. Husson

Patent number: 6287790Abstract: The localization of nuclear apparatus proteins (NUMA) is used to identify tumor cells and different stages in the tumor progression and differentiation processes. There is a characteristic organization of NuMA in tumor cells and in phenotypically normal cells. NuMA distribution patterns are significantly less diffuse in proliferating non-malignant cells compared to malignant cells. The technique encompasses cell immunostaining using a NuMA specific antibody, and microscopic analysis of NuMA distribution within each nucleus.Type: GrantFiled: November 30, 1999Date of Patent: September 11, 2001Assignee: The Regents of the University of CaliforniaInventors: Sophie Lelièvre, Mina Bissell
