Patent number: 10435639Abstract: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizes a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to ceric ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Ce1-xMxO2, wherein “x” has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 nm. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.Type: GrantFiled: December 17, 2008Date of Patent: October 8, 2019Assignee: Cerion, LLCInventors: Albert Gary Difrancesco, Thomas D.

Patent number: 10279393Abstract: The present process provides a method for synthesizing oxide-free copper nanometal dispersion in a free and reduced state using a solution phase synthesis process. A solution of an organic reducing agent containing at least two proximal nitrogen atoms is reacted with a separate solution containing a copper salt reformulated into a charge transfer complex. The reaction products are stabilized with Lewis bases and Lewis acids and optionally can be concentrated by removing a portion of the volatile low molecular weight solvent by either the use of a partial vacuum or by chemical extraction into another phase.Type: GrantFiled: July 17, 2017Date of Patent: May 7, 2019Assignee: ZEROVALENT NANOMETALS, INC.Inventor: Kenneth J.
