Patent number: 10388947Abstract: Graphitic carbon nitride materials are shown to be useful in Lithium-Sulfur electrochemical cells. Batteries that include this material exhibit increased electrode kinetics of the lithium-sulfur electrochemical couple, phenomena that improve the specific capacity, usable lifetime and other desirable characteristics of these batteries. Lithium-sulfur batteries that incorporate these materials can be used to overcome a number of limitations in this technology.Type: GrantFiled: February 6, 2015Date of Patent: August 20, 2019Assignees: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, MITSUBISHI CHEMICAL CORPORATIONInventors: Young-Si Jun, Jeffrey A.

Publication number: 20190002787Abstract: Disclosed herein are star-shaped macromolecular structures comprising a hyper-branched silicon containing core grafted with a well-defined and controllable number of alkyl (methyl)acrylate (co)polymer arms. The presence of the robust inorganic core provides additional resilience against mechanical degradation and therefore enhanced additive life time. Control over the additive architecture was complemented by tunability of the length of the grafted polymers by making use of controlled radical based polymerization techniques. The performance of these novel inorganic-organic star-shaped hybrids were compared to traditional fully organic lubricant additives. Detailed analysis revealed the multi-functional character of the hybrids by simultaneously performing as bulk viscosity modifiers, boundary lubricant, and wear protectants while being dispersed in a commercially available base oil for automotive lubrication purposes.Type: ApplicationFiled: July 2, 2018Publication date: January 3, 2019Applicant: The Regents of the University of CaliforniaInventors: Bas van Ravensteijn, Raghida Bou Zerdan, Watanabe Takumi, Dongjin Seo, Nicholas Cadirov, Jeffrey Gerbec, Craig J.

Patent number: 8414746Abstract: A method is provided for producing crystalline nanoparticle semiconductor material. The method includes the steps of mixing a precursor in a solvent to form a reaction mixture and subjecting the reaction mixture to microwave dielectric heating at sufficient power to achieve a superheating temperature of the reaction mixture. A growth-phase reaction is permitted to proceed, wherein nanoparticles are formed in the heated reaction mixture. The reaction is then quenched to substantially terminate nanoparticle formation.Type: GrantFiled: July 27, 2006Date of Patent: April 9, 2013Assignee: Florida State University Research Foundation, Inc.Inventors: Geoffrey F. Strouse, Jeffrey A. Gerbec
