Publication number: 20100000762Abstract: A metallic composition including a solvent and a plurality of metal nanoparticles dispersed therein is formulated such that curing of the metallic composition on a substrate provides a metallic conductor with a resistivity of about 5×10?4 ?·cm or less. Electrical components of an assembly can be interconnected by a metallic conductor formed by curing the metallic composition on a substrate. A metallic composition including metal nanoparticles can be deposited on a substrate and solidified. The metallic composition can be contacted with a metal wire before or after solidification of the metallic composition and secured to the solidified metallic composition.Type: ApplicationFiled: July 1, 2009Publication date: January 7, 2010Applicant: Applied Nanotech Holdings, Inc.Inventors: Mohshi Yang, David Max Roundhill, Zvi Yaniv

Publication number: 20090311440Abstract: A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.Type: ApplicationFiled: May 14, 2009Publication date: December 17, 2009Applicant: Applied Nanotech Holdings, Inc.Inventors: Yunjun Li, David Max Roundhill, Mohshi Yang, Igor Pavlovsky, Richard Lee Fink, Zvi Yaniv

Patent number: 7560134Abstract: A method for forming a coating of nano-sized material on the surface of another material using a micromachining bead-blasting machine for implantation of nanoparticles is disclosed. The method can be practiced with a wide range of target materials, nanoparticles (such as carbon-nanotubes, CNTs), and environmental conditions, using a wide range of carrier bead sizes and materials, or without carrier beads.

Patent number: 7367215Abstract: The present invention provides for variable-range hydrogen sensors and methods for making same. Such variable-range hydrogen sensors comprise a series of fabricated Pd—Ag (palladium-silver) nanowires—each wire of the series having a different Ag to Pd ratio—with nanobreakjunctions in them and wherein the nanowires have predefined dimensions and orientation. When the nanowires are exposed to H2, their lattice swells when the H2 concentration reaches a threshold value (unique to that particular ratio of Pd to Ag). This causes the nanobreakjunctions to close leading to a 6-8 orders of magnitude decrease in the resistance along the length of the wire and providing a sensing mechanism for a range of hydrogen concentrations.Type: GrantFiled: July 14, 2006Date of Patent: May 6, 2008Assignee: Nano-Proprietary, Inc.Inventors: Greg Monty, Kwok Ng, Mohshi Yang

Patent number: 7237429Abstract: The present invention provides for novel hydrogen sensors and methods for making same. In some embodiments, such novel hydrogen sensors are continuous-range hydrogen sensors comprising Pd—Ag nanoparticles arrayed as nanowires or two-dimensional shapes on a resistive surface. Such continuous-range hydrogen sensors are capable of measuring a wide range of hydrogen gas concentration over a wide temperature range. Unlike existing hydrogen sensors that experience a large change in resistance at a certain hydrogen concentration, the continuous-range hydrogen sensor of the present invention changes resistance continuously over a broad range of hydrogen concentration. This continuous change varies slowly with hydrogen concentration and is predictable such that the continuous-range hydrogen sensor can be used to measure hydrogen concentration continuously from a few ppm to 40,000 ppm level or higher over a broad range of temperatures (e.g., ?40° C. to +150° C.).Type: GrantFiled: February 22, 2005Date of Patent: July 3, 2007Assignee: Nano-Proprietary, Inc.Inventors: Greg Monty, Kwok Ng, Mohshi Yang, Richard Finh

Publication number: 20060252163Abstract: A method for forming a field emission cathode device is disclosed using a peelable photoresist with standard photolithography processes for patterning a deposition mask, except that the peelable photoresist can be peeled away in dry form. The method offers standard photoresist accuracy with the advantage of high patterning resolution for producing carbon nanotube (CNT) field emitter displays. Example methods using a single peelable photoresist layer, and using two distinct layers of photoresist and peelable film, are presented. Since the method does not require wet processes after CNT deposition, it ensures enhanced CNT emitter performance. In addition, an activation process that liberates CNTs can be performed just before a tape lamination and peeling process step. In this manner, all superfluous nanoparticle material remains confined between the tape and photoresist films, which are removed together and properly discarded.Type: ApplicationFiled: January 27, 2006Publication date: November 9, 2006Applicant: Nano-Proprietary, Inc.Inventors: Zvi Yaniv, Mohshi Yang, Dongsheng Mao
