Publication number: 20150064442Abstract: A method of rapidly fabricating a graphene-based nanocomposite using oxidation-reduction and a graphene-based nanocomposite fabricated by the same method. A solution in which a graphene oxide is dispersed is prepared. A source material for a metal oxide is added into the solution in which the graphene oxide is dispersed. A nanocomposite is formed by forming the metal oxide on at least one surface of graphene that is reduced using oxidation-reduction between the graphene oxide and the source material for the metal oxide. The reduction voltage of the source material for the metal oxide is 1.0 V or less.Type: ApplicationFiled: August 28, 2014Publication date: March 5, 2015Inventors: KwangBum Kim, JongPil Jegal, Hyun Kyung Kim, SeungBum Yoon, MyeongSeong Kim

Publication number: 20150030872Abstract: A method of surface coating a metallic object, including removing substantially all of the existing silver sulfide tarnish if present, ultrasonically cleaning the object with immersion in a solvent, uniformly dispersing selected nanoparticles over the surface of the object by sonicating the object in an ultrasonic bath containing the selected nanoparticles. The invention further includes quickly rinsing the object with solvent upon removal from the ultrasonic bath to inhibit formation of large agglomerates, drying the object with a flow of gas, optically inspecting the object for the presence of agglomeration and applying a barrier layer conformal coating and a protective layer conformal coating.Type: ApplicationFiled: August 12, 2014Publication date: January 29, 2015Inventors: Suneeta S.
