Patent number: 9308585Abstract: Various embodiments provide methods of forming zero valent metal particles using an aerosol-reductive/expansion synthesis (A-RES) process. In one embodiment, an aerosol stream including metal precursor compound(s) and chemical agent(s) that produces reducing gases upon thermal decomposition can be introduced into a heated inert atmosphere of a RES reactor to form zero valent metal particles corresponding to metals used for the metal precursor compound(s).Type: GrantFiled: November 10, 2011Date of Patent: April 12, 2016Assignee: STC.UNMInventors: Zayd Leseman, Claudia Luhrs, Jonathan Phillips, Haytham Soliman

Patent number: 8642139Abstract: Disclosed is a process for making a composite material that contains structured particles. The process includes providing a first precursor in the form of a dry precursor powder, a precursor liquid, a precursor vapor of a liquid and/or a precursor gas. The process also includes providing a plasma that has a high field zone and passing the first precursor through the high field zone of the plasma. As the first precursor passes through the high field zone of the plasma, at least part of the first precursor is decomposed. An aerosol having a second precursor is provided downstream of the high field zone of the plasma and the decomposed first material is allowed to condense onto the second precursor to from structured particles.Type: GrantFiled: June 9, 2009Date of Patent: February 4, 2014Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., STC.UNMInventors: Angela Michelle Knapp, Monique N. Richard, Claudia Luhrs, Timothy Blada, Jonathan Phillips

Patent number: 8623470Abstract: Disclosed is a process for making a composite material that contains core-shell structured nanoparticles. The process includes providing a precursor in the form of a powder a liquid and/or a vapor of a liquid that contains a core material and a shell material, and suspending the precursor in an aerosol gas to produce an aerosol containing the precursor. In addition, the process includes providing a plasma that has a hot zone and passing the aerosol through the hot zone of the plasma. As the aerosol passes through the hot zone of the plasma, at least part of the core material and at least part of the shell material in the aerosol is vaporized. Vapor that contains the core material and the shell material that has been vaporized is removed from the hot zone of the plasma and allowed to condense into core-shell structured nanoparticles.Type: GrantFiled: June 20, 2008Date of Patent: January 7, 2014Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., STC.UNMInventors: Claudia Luhrs, Jonathan Phillips, Monique N.

Patent number: 8277872Abstract: Methods of manufacturing a carbon structure including exposing a carbon fiber substrate to oxygen at a first predetermined temperature and activating the carbon fiber substrate by exposure to oxygen at a second predetermined temperature. A catalyst including palladium is deposited on the activated carbon fiber substrate. The deposited catalyst on the carbon fiber structure is exposed to a hydrocarbon at a third predetermined temperature to grow carbon structures thereon. The carbon structures grown can be multimodal in nature with structures that are nano-scale and/or submicron-scale.Type: GrantFiled: November 12, 2009Date of Patent: October 2, 2012Assignee: STC.UNMInventors: Marwan S.

Patent number: 8057900Abstract: Disclosed is a material having a composite particle, the composite particle including an outer shell and a core. The core is made from a lithium alloying material and the outer shell has an inner volume that is greater in size than the core of the lithium alloying material. In some instances, the outer mean diameter of the outer shell is less than 500 nanometers and the core occupies between 5 and 99% of the inner volume. In addition, the outer shell can have an average wall thickness of less than 100 nanometers.Type: GrantFiled: June 20, 2008Date of Patent: November 15, 2011Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Regents of the University of New MexicoInventors: Claudia Luhrs, Monique N.

Publication number: 20110006254Abstract: A process for making an first material/second material nanocomposite is disclosed. The process can include providing a precursor that contains an electrochemically active and an electrochemically inactive material. Thereafter, the precursor can be suspended in an aerosol gas to produce an aerosol and a plasma having a high field zone can be provided. The aerosol can be passed through the high field zone of the plasma and result in the vaporization of at least part of the precursor in the aerosol. The precursor that has been vaporized in the high field zone is subsequently removed therefrom and allowed to condense into an first material/second material nanocomposite with at least one electrochemically active material.Type: ApplicationFiled: July 7, 2009Publication date: January 13, 2011Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., Regents of the University of New Mexico, Los Alamos National Security, LLCInventors: Monique N.
