Patent number: 9870840Abstract: According to example embodiments, a metallic glass includes aluminum (Al), a first element group, and a second element group. The first element group includes at least one of a transition metal and a rare earth element. The second element group includes at least one of an alkaline metal, an alkaline-earth metal, a semi-metal, and a non-metal. The second element group and aluminum have an electronegativity difference of greater than or equal to about 0.25. The second element group is included less than or equal to about 3 at % of the metallic glass, based on the total amount of the aluminum (Al), the first element group, and the second element group. A conductive paste and/or an electrode of an electronic device may be formed using the metallic glass.Type: GrantFiled: January 2, 2014Date of Patent: January 16, 2018Assignees: Samsung Electronics Co., Ltd., Yonsi University, University-Industry Foundation (UIF)Inventors: Jin Man Park, Keum Hwan Park, Eun Sung Lee, Suk Jun Kim, Se Yun Kim, Sang Soo Jee, Do-hyang Kim

Patent number: 9309587Abstract: A plasma spray nozzle is provided. Owing to their high degree of wear, previous plasma spray nozzles were not suitable for the coating of components for which long coating times were necessary. The coating times may be reduced considerably by the triple injection of powder into the inner channel through the plasma spray nozzle.Type: GrantFiled: August 7, 2013Date of Patent: April 12, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Mario Felkel, Heiko Gruner, Francis Ladru

Patent number: 9299505Abstract: In one embodiment of the invention, a method of forming an energy storage device is described in which a porous structure of an electrically conductive substrate is measured in-situ while being electrochemically etched in an electrochemical etching bath until a predetermined value is obtained, at which point the electrically conductive substrate may be removed from the electrochemical etching bath. In another embodiment, a method of forming an energy storage device is described in which an electrically conductive porous structure is measured to determine the energy storage capacity of the electrically conductive porous structure. The energy storage capacity of the electrically conductive porous structure is then reduced until a predetermined energy storage capacity value is obtained.Type: GrantFiled: December 14, 2011Date of Patent: March 29, 2016Assignee: Intel CorporationInventors: Eric C.
