Abstract: Multiphase microspheres for radioembolization include two-phase microspheres and three-phase microspheres prepared by a microfluidic process. The multiphase microspheres include a primary phase and a first secondary phase surrounded by the primary phase. The primary phase includes a first resin. The first secondary phase includes a second resin and at least one of a radioactive isotope or a compound including at least one radioactive element. Three-phase microspheres additionally include a second secondary phase discrete from the first secondary phase and also surrounded by the primary phase. The second secondary phase may be a gas such as air. The microspheres may be formed by a microfluidic process.

Abstract: A corrosion resistant, electrically-conductive, durable plate at least partially coated with an anchor coating and a corrosion resistant coating. The corrosion resistant coating made of at least a polymer and a plurality of corrosion resistant particles each having a surface area between about 1-20 m2/g and a diameter less than about 10 microns. Preferably, the plate is used as a bipolar plate in a proton exchange membrane (PEMFC) fuel cell stack.

Abstract: Compressive composite seals for solid oxide fuel cell applications are provided. A compressive composite seal structure includes a glass phase to provide a gas tight seal, a reinforcing secondary phase to provide mechanical stability, and a compressive core. The compressive core is filled with an inert gas or air, providing a degree of compressibility, or alternatively is filled with a selected material to provide a more specific degree of compressibility and strength, such as a lower melting point glass. The compressive composite seal structure maintains an effective seal during the operating conditions of the SOFC. The self healing glass phase with the reinforcing secondary phase providing mechanical stability provides an elastic response at high temperature, effectively reduces crack propagation and if the temperature or pressure goes too high, the seal remains reliable and effective.

Abstract: A composition of matter and method of use of an electrode for intermediate temperature electrochemical devices. An electrode consists essentially of a perovskite based oxide having a composition of La1-xSr1-xMn1-yCryO3-? and the electrode can be used at intermediate operating temperatures of 650-800° C.

Abstract: A method for producing composite ceramic material is provided wherein a core ceramic structure is produced and simultaneously enveloped with a sleeve of similar material.

Abstract: A bipolar plate supported solid oxide fuel cell with a sealed anode compartment is provided. The solid oxide fuel cell includes a cathode, an electrolyte, and an anode, which are supported on a metallic bipolar plate assembly including gas flow fields and the gas impermeable bipolar plate. The electrolyte and anode are sealed into an anode compartment with a metal perimeter seal. An improved method of sealing is provided by extending the metal seal around the entire perimeter of the cell between an electrolyte and the bipolar plate to form the anode compartment. During a single-step high temperature sintering process the metal seal bonds to the edges of the electrolyte and anode layers, the metal foam flow field and the bipolar plate to form a gastight containment.
