Patent number: 8993472Abstract: Layered catalyst structures for fuel cells, particularly for a Proton Exchange Membrane Fuel Cell (PEMFC), are produced by a reactive spray deposition technology process. The catalyst layers so produced contain particles sized between 1 and 15 nm and clusters of such particles of a catalyst selected from the group consisting of platinum, platinum alloys with transition metals, mixtures thereof and non-noble metals. The catalyst layers without an electrically conducting supporting medium exhibit dendritic microstructure, providing high electrochemically active surface area and electron conductivity at ultra-low catalyst loading. The catalyst layers deposited on an electrically conducting medium, such as carbon, exhibit three-dimensional functional grading, which provides efficient utilization as a catalyst, high PEMFC performance at the low catalyst loading, and minimized limitations caused by reactant diffusion and activation. The catalytic layers may be produced by a single-run deposition method.Type: GrantFiled: November 6, 2009Date of Patent: March 31, 2015Assignee: National Research Council of CanadaInventors: Justin Roller, Radenka Maric, Khalid Fatih, Roberto Neagu

Patent number: 8987417Abstract: The present invention addresses limitations of prior art receptor-based traps through a methodology called the clamp/click/cleave (CCC) approach. Two fusion proteins each comprising a binding domain fused to a coiled-coil are non-covalently dimerized through the coiled-coil (clamp), and the dimer so formed is stabilized by a covalent disulphide bond (click) between cysteine residues located on the fusion proteins between the binding domains and coiled-coils. Once the disulphide bond has formed, the coiled-coils are subsequently removed (cleave) by cleaving the fusions proteins at cleavage sites located between the cysteine residues and the coiled-coils to provide the covalently dimerized bivalent binding agent of the present invention. Such binding agents are useful in the treatment and diagnosis of disease states characterized by production and/or overexpression of a ligand to which the binding domains bind.Type: GrantFiled: November 28, 2011Date of Patent: March 24, 2015Assignee: National Research Council of CanadaInventors: John C.

Publication number: 20150055130Abstract: A method for producing a multilayer tissue phantom involves successively forming at least two layers, each layer formed by depositing a viscous flowable material over a supporting element or over a previously formed layer of the phantom supported by the supporting element, selectively redistributing the material while material is solidifying to control a thickness distribution of the layer, and allowing the material to solidify sufficiently to apply a next layer. The supporting element supports the material in 2 or 3 directions and effectively molds a lumen of the tissue. The neighbouring layers are of different composition and of chosen thickness to provide desired optical properties and mechanical properties of the phantom. The phantom may have selected attenuation and backscattering properties to mimic tissues for optical coherence tomography imaging.Type: ApplicationFiled: November 7, 2014Publication date: February 26, 2015Applicant: NATIONAL RESEARCH COUNCIL OF CANADAInventors: Charles-Etienne BISAILLON, Guy LAMOUCHE, Marc L.
