Publication number: 20100151147Abstract: The invention discloses a metal pattern formation method including the following steps. At first, an organic liquid is printed on a substrate to form a base pattern. Afterward, a metal is evaporated to generate several metal particles for covering the printed substrate. At last, the substrate is heated to vaporize the base pattern, and the metal particles adhered to the substrate forms a metal pattern complementary to the base pattern.Type: ApplicationFiled: December 13, 2008Publication date: June 17, 2010Inventors: Li-Jiuan Chen, Chien-Ho Huang, Hsiou-Jeng Shy, Shang-Wano Yeh, Ching-Yu Tso

Publication number: 20100143431Abstract: The invention relates to the production and use of novel bioactive devices and metallic coatings for example for sterilizing, disinfecting, and decontaminating water or aqueous solutions. The known oligodynamic effect of silver for reducing the amount of germs is thereby improved and increased by combining silver with ruthenium and a vitamin or derivative thereof. The novel properties of these bioactive metal surfaces lead to faster and more efficient killing of microorganisms. Simultaneously, these novel bioactive metal surfaces prevent infestation by microorganisms and attachment or permanent deposition of problematic biomolecules such as for example DNA, RNA, or proteins. A self-cleaning surface is thus obtained, which very quickly and efficiently and over extended periods of time sterilizes water and aqueous solutions when they come in contact with said surface.Type: ApplicationFiled: October 2, 2007Publication date: June 10, 2010Applicant: AGXX INTELLECTUAL PROPERTY HOLDING GMBHInventors: Uwe Landau, Thomas Lisowsky, Karlheinz Esser, Klaus-Dieter Mehler

Publication number: 20100108254Abstract: The present invention relates generally to a metallic alloy composed of Titanium and Tungsten that together form an alloy having a Coefficient of Thermal Expansion (CTE), wherein the content of the respective constituents can be adjusted so that the alloy material can be nearly perfectly matched to that of a commonly used semiconductor and ceramic materials. Moreover, alloys of Titanium-Tungsten have excellent electrical and thermal conductivities making them ideal material choices for many electrical, photonic, thermoelectric, MMIC, NEMS, nanotechnology, power electronics, MEMS, and packaging applications. The present invention describes a method for designing the TiW alloy so as to nearly perfectly match the coefficient of thermal expansion of a large number of different types of commonly used semiconductor and ceramic materials.Type: ApplicationFiled: June 30, 2009Publication date: May 6, 2010Applicant: Corporation for National Research InitiativesInventors: Michael A.
