Patent number: 9533352Abstract: A process for preparing intermetallic nanoparticles of two or more metals is provided. In particular, the process includes the steps: a) dispersing nanoparticles of a first metal in a solvent to prepare a first metal solution, b) forming a reaction mixture with the first metal solution and a reducing agent, c) heating the reaction mixture to a reaction temperature; and d) adding a second metal solution containing a salt of a second metal to the reaction mixture. During this process, intermetallic nanoparticles, which contain a compound with the first and second metals are formed. The intermetallic nanoparticles with uniform size and a narrow size distribution is also provided. An electrochemical device such as a battery with the intermetallic nanoparticles is also provided.Type: GrantFiled: November 3, 2015Date of Patent: January 3, 2017Assignee: UChicago Argonne, LLCInventors: Dileep Singh, Yusuf Yusufoglu, Elena Timofeeva, Jules L.

Patent number: 9340720Abstract: A nanofluid of a base heat transfer fluid and a plurality of ceramic nanoparticles suspended throughout the base heat transfer fluid applicable to commercial and industrial heat transfer applications. The nanofluid is stable, non-reactive and exhibits enhanced heat transfer properties relative to the base heat transfer fluid, with only minimal increases in pumping power required relative to the base heat transfer fluid. In a particular embodiment, the plurality of ceramic nanoparticles comprise silicon carbide and the base heat transfer fluid comprises water and water and ethylene glycol mixtures.Type: GrantFiled: June 30, 2010Date of Patent: May 17, 2016Assignee: UChicago Argonne, LLCInventors: Dileep Singh, Jules Routbort, A.J. Routbort, Wenhua Yu, Elena Timofeeva, David S. Smith, David M. France
