Abstract: A cement composition comprises free-flowing spray-dried unreacted cement particles and a liquid binder. The spray-dried particles may include a poly acid. A method for making a cement composition using spray dried cement particles comprises a) providing cement particles, b) milling or sieving said cement particles so as to produce cement particles having a desired average size, c) adding a liquid carrier to said particles before or after milling so as to form a slurry, d) adding a poly acid to said particles while maintaining the pH of the slurry above about 6, and e) spray-drying the slurry. The resulting particles can be used in conjunction with a liquid binder to form a monolith having a desired shape.

Abstract: A spray-dryable cement composition comprises unreacted cement particles and a salt of a poly-acid. The composition can be used in a method for solid free-form fabrication of a three-dimensional object, in which a slurry comprising unreacted cement particles and a poly acid in a liquid carrier is spray-dried so as to substantially remove the carrier and form dry cement particles, the cement particles are deposited in a defined region and a liquid binder is applied to a predetermined area within the defined region such that upon contact of the liquid binder with the cement particles a hydrated cement forms in the predetermined area, and the steps of depositing the cement and applying the binder are repeated so as to form a three dimensional object.

Abstract: A semiconductor package includes a substrate having a first surface portion in a cavity. The first surface portion includes an artificially formed grass structure. The package includes a getter film formed over the grass structure.

Abstract: The present invention provides a solid oxide fuel cell system comprising at least one fuel cell and at least one gas flow channel to deliver a reactant mixture. The fuel cell comprises at least one chamber to house at least one anode, at least one cathode, and at least one electrolyte, and the fuel cell is adapted to receive a reactant mixture comprising reactants mixed prior to delivery to the fuel cell. The one or more gas flow channels for delivering the reactant mixture have characteristic dimensions that are less than a quench distance of the reactant mixture at an operating temperature within the solid oxide fuel cell system.

Abstract: A fuel cell assembly includes a plurality of opposing fuel cell stacks. Each of the fuel stacks has a plurality of fuel cells in which each fuel cell has an anode, a cathode, and an electrolyte. The fuel cell assembly further includes a spacing member disposed between the fuel cell stacks thereby defining a fluidic cavity.

Abstract: A fuel cell layer includes a substrate, an array of fuel cells each having an anode, a cathode, and an electrolyte disposed on the substrate, conductors electrically coupled to the fuel cell array, a fuel flow channel defined in an anode side of the substrate; and a cathode air flow channel defined in a cathode side of the substrate.

Abstract: A method for solid free-form fabrication of a three-dimensional metal object includes depositing a particulate blend in a defined region, the particulate blend including a number of metal or metal alloy particulates and a peroxide, and selectively ink-jetting a binder system onto a predetermined area of the particulate blend to form a green part, wherein the liquid phase binder includes a water soluble monofunctional acrylate-based monomer, a water soluble difunctional acrylate-based monomer, an amine, and water.

Abstract: A MEMS-based fuel cell has a substrate, an electrolyte in contact with the substrate, a cathode in contact with the electrolyte, an anode spaced apart from the cathode and in contact with the electrolyte, and an integral manifold for supplying either a fuel or an oxidant or both together, the integral manifold extending over at least a portion of the electrolyte and over at least one of the anode and cathode. Methods for making and using arrays of the fuel cells are disclosed.
