Patent number: 8318255Abstract: Metallic substrates have a surface for receiving application of an adhesive that includes a precipitated coating of metallic nanoparticulates. A first portion of the nanoparticulates is adhered to the surface and a second portion is in contact with the first portion. Also provided are adhered constructs. These constructs include a first substrate with a first surface that has a metallic precipitated coating of nanoparticulates. A first portion of the nanoparticulates is adhered to the surface and a second portion contacts the first portion. The constructs include a second substrate that has a second surface; and an adhesive is applied between the first surface and the second surface.Type: GrantFiled: November 8, 2010Date of Patent: November 27, 2012Assignee: The Boeing CompanyInventor: Julia J. Mack

Patent number: 8313797Abstract: Provided is a method for in-situ coating a substrate or matrix with magnetic metal nanoparticles. A metal salt, which may be organic or inorganic, is introduced into a solution of liquid polyol. In the presence of mechanical stirring and heat, a reduction process occurs wherein the magnetic metal nanoparticles precipitate out of solution and deposit or attach to one or more surfaces of the substrate. The concentration of reaction precursors, combined with the polyol, may be varied to control the size and shape of the magnetic nanoparticles.Type: GrantFiled: April 15, 2009Date of Patent: November 20, 2012Assignee: Teledyne Scientific & Imaging, LLCInventors: Julia J. Mack, Brian N. Cox, Vivek Mehrotra, Ten-Luen T. Liao, Rahul Ganguli

Patent number: 8075794Abstract: Provided is a magnetic graphite nanoplatelet, and a method of manufacturing nanocomposites by introducing the magnetic nanoplatelets into a composite matrix. Expanded crystalline graphite, in the form of graphite nanoplatelets, is mixed with magnetic particles to adhere the particles to the nanoplatelets. The magnetic graphite nanoplatelets are combined with a composite matrix, typically a polymer, to form a nanocomposite. In the presence of an applied magnetic field, the magnetic graphite nanoplatelets orient and align consistent with the magnetic field to yield a composite having enhance mechanical, electrical and thermal properties.Type: GrantFiled: July 1, 2008Date of Patent: December 13, 2011Assignee: Teledyne Scientific & Imaging, LLCInventors: Rahul Ganguli, Julia J.

Patent number: 7823529Abstract: To produce a ceramic foam-filled structural sandwich panel, a coating of a pre-ceramic slurry is applied on a preform. The preform includes a foam template sandwiched between a plurality of panels. In addition, the coating is cured to the preform, the preform is modified, and the coating is converted to a ceramic.Type: GrantFiled: May 23, 2006Date of Patent: November 2, 2010Assignee: The Boeing CompanyInventors: Julia J.

Patent number: 6872330Abstract: A low temperature chemical route to efficiently produce nanomaterials is described. The nanomaterials are synthesized by intercalating ions into layered compounds, exfoliating to create individual layers and then sonicating to produce nanotubes, nanorods, nanoscrolls and/or nanosheets. It is applicable to various different layered inorganic compounds (for example, bismuth selenides/tellurides, graphite, and other metal complexes, particularly transition metal dichalcogenides compounds including oxygen, sulfur, tellurium or selenium).Type: GrantFiled: May 30, 2002Date of Patent: March 29, 2005Assignee: The Regents of the University of CaliforniaInventors: Julia J Mack, Lisa M.
