Patent number: 7767272Abstract: A method of producing compound nanorods and thin films under a controlled growth mode is described. The method involves ablating compound targets using an ultrafast pulsed laser and depositing the ablated materials onto a substrate.

Publication number: 20090176110Abstract: A coating system and process capable of providing erosion and corrosion-resistance to a component, particularly a steel compressor blade of an industrial gas turbine. The coating system includes a metallic sacrificial undercoat on a surface of the component substrate, and a ceramic topcoat deposited by thermal spray on the undercoat. The undercoat contains a metal or metal alloy that is more active in the galvanic series than iron, and electrically contacts the surface of the substrate. The ceramic topcoat consists essentially of a ceramic material chosen from the group consisting of mixtures of alumina and titania, mixtures of chromia and silica, mixtures of chromia and titania, mixtures of chromia, silica, and titania, and mixtures of zirconia, titania, and yttria.Type: ApplicationFiled: January 8, 2008Publication date: July 9, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: Surinder Singh Pabla, Jon Conrad Schaeffer, Vinod Kumar Pareek, David Vincent Bucci, Thomas Moors, Jane Marie Lipkin

Patent number: 7556189Abstract: Nano-structured interconnect formation and a reworkable bonding process using solder films. Large area fabrication of nano-structured interconnects is demonstrated at a very fine pitch. This technology can be used for pushing the limits of current flip chip bonding in terms of pitch, number of I/Os, superior combination of electrical and mechanical properties as well as reworkability. Sol-gel and electroless processes were developed to demonstrate film bonding interfaces between metallic pads and nano interconnects. Solution-derived nano-solder technology is an attractive low-cost method for several applications such as MEMS hermetic packaging, compliant interconnect bonding and bump-less nano-interconnects.Type: GrantFiled: May 26, 2005Date of Patent: July 7, 2009Assignee: Georgia Tech Research CorporationInventors: Ankur Aggarwal, Isaac Robin Abothu, Pulugurtha Markondeya Raj, Rao R.

Publication number: 20090162670Abstract: A method for applying a ceramic coating over a substantially smooth protective coating on a metal substrate is disclosed. The method includes the step of air plasma spraying (APS) particles of the ceramic coating at a pre-selected particle velocity of at least about 500 meters per second. The ceramic coating particles have an average particle size no greater than about 50 microns. An article is also described, including a metal substrate; and a substantially smooth protective coating over the substrate, having a roughness (Ra) less than about 200 micro-inches. An adherent ceramic coating is disposed on the substantially smooth protective coating.Type: ApplicationFiled: December 20, 2007Publication date: June 25, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: Yuk-Chiu Lau, Brian Thomas Hazel

Patent number: 7544631Abstract: The present invention provides for titanium oxide-based photocatalysts having a general formula of TiO2-X-?CXN? and self-cleaning materials that are prepared by substituting O of pure TiO2 with C and N. A preparation method comprising a process for forming thin films of TiO2-X-?CXN? by using gases such as Ar, N2, CO2, CO and O are used for reactive sputtering, and a process of heat treating at around 500° C., thereby crystallizing, is provided. The titanium oxide-based photocatalysts having a general formula of TiO2-X-?CXN? and self-cleaning materials according to the present invention have a smaller optical bandgap compared to pure titanium oxides, and therefore, the photocatalysts can be activated under the visible light range. In addition, they comprise only pure anatase crystallization phase, and since the crystallized particles are small in size, the efficiency and self-cleaning effect of the photocatalysts are very high.Type: GrantFiled: April 26, 2006Date of Patent: June 9, 2009Assignee: Korea Institute of Science and TechnologyInventors: Won-Kook Choi, Yeon-Sik Jung, Dong-Heon Kang, Kyung-Ju Lee
