Publication number: 20180354164Abstract: An apparatus 20 and a method 100 for generating and dispensing a powdered 60 release agent during an additive manufacturing build is disclosed. A solid body 28 of release agent material is ground insitu by a grinder 50 and dispensed on a surface of the part 72 to prevent adhesion of an adjacent layer of a base material 70. With the addition of the powdered 60 release agent, a support structure 76 is easily separated from the base material 70 when the part 72 is complete, saving time and preventing the part 72 from sustaining unintentional damage. Since no powdered 60 release agent is actually loaded or stored in the apparatus 20, the potential for spillage, waste, inconsistent dispensing, inadvertent dispensing, and clumping due to humidity is eliminated.Type: ApplicationFiled: August 21, 2018Publication date: December 13, 2018Applicant: U T-Battelle, LLCInventors: Randall F. Lind, Brian K. Post, Phillip C. Chesser, Andrew P. Reis, Alex C. Roschli

Patent number: 7951535Abstract: An oligonucleotide-based SERS molecular probe (SMP) includes a nanoparticle having at least a metal component, and at least one pin loop, the pin loop including a loop sequence complementary to at least one target sequence, a first stem attached to one end of the loop sequence, a second stem attached to the other end of the loop sequence, and at least one SERS active label attached to the first stem. The nanoparticle is attached to the second stem. The probe generates a stronger SERS signal upon irradiation with excitation radiation when not bound to the target sequence as compared to the SERS signal generated following hybridization of the probe with the target sequence.Type: GrantFiled: January 10, 2008Date of Patent: May 31, 2011Assignee: U-T Battelle, LLCInventor: Tuan Vo-Dinh

Patent number: 7257945Abstract: A method to use diesel fuel alchohol micro emulsions (E-diesel) to provide a source of reductant to lower NOx emissions using selective catalytic reduction. Ethanol is stripped from the micro emulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel (and other lean-burn) engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.Type: GrantFiled: February 10, 2003Date of Patent: August 21, 2007Assignee: U T Battelle, LLCInventors: Michael Delos Kass, Ronald Lee Graves, John Morse Elliot Storey, Samuel Arthur Lewis, Sr., Charles Scott Sluder, John Foster Thomas

Patent number: 6436346Abstract: A method and apparatus are provided for detecting and monitoring micro-volumetric enthalpic changes caused by molecular reactions. Micro-machining techniques are used to create very small thermally isolated masses incorporating temperature-sensitive circuitry. The thermally isolated masses are provided with a molecular layer or coating, and the temperature-sensitive circuitry provides an indication when the molecules of the coating are involved in an enthalpic reaction. The thermally isolated masses may be provided singly or in arrays and, in the latter case, the molecular coatings may differ to provide qualitative and/or quantitative assays of a substance.Type: GrantFiled: September 14, 1999Date of Patent: August 20, 2002Assignee: U T Battelle, LLCInventors: Mitchel J.

Patent number: 6375705Abstract: Oxide dispersion strengthening of porous metal articles includes the incorporation of dispersoids of metallic oxides in elemental metal powder particles. Porous metal articles, such as filters, are fabricated using conventional techniques (extrusion, casting, isostatic pressing, etc.) of forming followed by sintering and heat treatments that induce recrystallization and grain growth within powder grains and across the sintered grain contact points. The result is so-called “oxide dispersion strengthening” which imparts, especially, large increases in creep (deformation under constant load) strength to the metal articles.Type: GrantFiled: March 26, 1999Date of Patent: April 23, 2002Assignee: U. T. Battelle, LLCInventor: Roddie R. Judkins

Patent number: 6358396Abstract: Anion exchange resins sorbed with perchlorate may be regenerated by a combination of chemical reduction of perchlorate to chloride using a reducing agent and an electrochemical reduction of the oxidized reducing agent. Transitional metals including Ti, Re, and V are preferred chemical reagents for the reduction of perchlorate to chloride. Complexing agents such as oxalate are used to prevent the precipitation of the oxidized Ti(IV) species, and ethyl alcohol may be added to accelerate the reduction kinetics of perchlorate. The regeneration may be performed by continuously recycling the regenerating solution through the resin bed and an electrochemical cell so that the secondary waste generation is minimized.Type: GrantFiled: May 8, 2000Date of Patent: March 19, 2002Assignee: U. T. Battelle, LLCInventors: Baohua Gu, Gilbert M. Brown

Patent number: 6251280Abstract: The present invention relates generally to mesoporous sorbent materials having high capacity, high selectivity, fast kinetics, and molecular recognition capability. The invention also relates to a process for preparing these mesoporous substrates through molecular imprinting techniques which differ from convention techniques in that a template molecule is bound to one end of bifunctional ligands to form a complex prior to binding of the bifunctional ligands to the substrate. The present invention also relates to methods of using the mesoporous sorbent materials, for example, in the separation of toxic metals from process effluents, paints, and other samples; detection of target molecules, such as amino acids, drugs, herbicides, fertilizers, and TNT, in samples; separation and/or detection of substances using chromatography; imaging agents; sensors; coatings; and composites.Type: GrantFiled: September 15, 1999Date of Patent: June 26, 2001Assignees: University of Tennessee Research Corporation, U.
