Patent number: 9878516Abstract: A metamaterial thin film with plasmonic properties formed by depositing metallic films by atomic layer deposition onto a substrate to form a naturally occurring mosaic-like nanostructure having two-dimensional features with air gaps between the two-dimensional features. Due to the unique deposition nanostructure, plasmonic thin films of metal or highly conducting materials can be produced on any substrate, including fabrics and biological materials. In addition, these plasmonic materials can be used in conjunction with geometric patterns that may be used to create multiple resonance plasmonic metamaterials.Type: GrantFiled: March 5, 2013Date of Patent: January 30, 2018Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Orest J. Glembocki, Sharka M Prokes, Joshua D. Caldwell, Mikko Ritala, Markku Leskela, Jaakko Niinisto, Eero Santala, Timo Hatanpaa, Maarit Kariemi

Publication number: 20160333476Abstract: The invention provides an improved method for producing cathode diffusion barrier layer, and a SOFC with high efficiency and longevity. It comprises depositing a pure ceria or aliovalently doped ceria layer, by ALD, on the electrolyte layer of the sintered half cell. The surface of a electrolyte onto which film is to be deposited is exposed to a dose of vapor from one or more lanthanide first precursors. Any excess of unreacted vapor from that precursor is removed. Next, a vapor dose of the second precursor is brought to the surface and allowed to react. A second purge completes the ALD cycle, which is repeated to build up thicker films. This ceria layer forms a cathode diffusion barrier layer on top of which a cobaltite based cathode layer is applied by screenprinting, and the cathode diffusion barrier layer and cathode layer are heated together to form a SOFC.Type: ApplicationFiled: January 14, 2014Publication date: November 17, 2016Inventors: Enn ÖUNPUU, Juhan SUBBI, Sanni SEPPÄLÄ, Jaakko NIINISTÖ, Markku LESKELÄ, Mikko RITALA
