Patent number: 10696916Abstract: Lubricant compositions, core-shell nanoparticles, and related methods are disclosed. In an exemplary embodiment, a lubricant composition includes a plurality of core-shell nanoparticles. The nanoparticles include a core, a first shell disposed on the core, and a second shell disposed on the first shell. The first shell is formed from a siliceous material and the second shell is formed from a hydrophobic material. The first and second shells form functional coatings that reduce wear and friction of parts lubricated with the lubricant composition.Type: GrantFiled: May 12, 2017Date of Patent: June 30, 2020Assignee: Board of Regents, The University of Texas SystemInventors: Pranesh Aswath, Richard B.

Patent number: 9120125Abstract: The present invention includes systems, methods and compositions for the encapsulation of particles. In one form, the system comprises one or more particles, a rotatable reaction chamber in a plasma enhanced chemical reactor to accept one or more particles, and at least one carbonaceous compound to be used in the rotatable reaction chamber, wherein the carbonaceous compound is polymerized onto a surface of one or more particles forming a polymer film encapsulating one or more particles. Using systems, methods, and compositions of the present invention, any particle encapsulated with a degradable or nondegradable polymer film may be introduced and/or released into an environment. The polymer film as well as introduction of encapsulated particles and release therefrom into an environment are controlled by the present invention.Type: GrantFiled: October 31, 2013Date of Patent: September 1, 2015Assignee: Board of Regents, The University of Texas SystemInventors: Richard B.
