Abstract: Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape).

Abstract: New methods and assays for multiplexed detection of analytes using phosphors that are uniform in morphology, size, and composition based on their unique optical lifetime signatures are described herein. The described assays and methods can be used for imaging or detection of multiple unique chemical or biological markers simultaneously in a single assay readout.

Abstract: Reinforced materials for high temperature superconducting tape. More specifically reinforcement materials for significantly reducing the amount of required reinforcement and attaining much higher stress tolerances at practical conductor dimensions are described herein.

Abstract: A chemical additive for reclaiming oil from a fluid product stream is described. In embodiments, chemical additive compositions comprise a propylene glycol ester, a hydrophobic silica, a polyglycol ester or a polyglycerol oleate ester, a polyethoxylate sorbitan or sorbitan ester and a block copolymer or ethylene oxide-propylene oxide polymer. Less chemical additive is needed for improved oil extraction and concentration and a shorter incubation time is required, which reduces cycle time and energy consumption.

Abstract: From one aspect, a method of forming a support for use in a selective sintering or melting process includes forming a body on a platen having a plurality of generally parallel channels each channel being open at least one end. The base of the channels may be formed by the platen. Preferably the support is formed by a selective sintering or melting process.

Abstract: This invention relates to a transparent or translucent transaction card having a base comprising a core of substantially transparent or translucent material with a plurality of coats, including optically recognizable ink comprising one or more infrared blocking dyes and other nanoparticles, such as rare earth nanophosphors and other metal nanoparticles, and/or optically recognizable film comprising nanoparticles, such as rare earth nanophosphors, and other metal oxide and/or non-oxide complexes, and methods for their preparation.

Abstract: This technology relates to a method of forming an aerated material for application to the surfaces of mines to minimize dust formation. The aerated material is comprised of rock dust and a foaming agent which is mixed with water, and when properly mixed and applied to a mine surface, creates a dry cellular structure with little caking.

Abstract: A method of forming an article includes forming a layer of a mixture of at least two distinct metal powders selected such that when combined they are chemically in the proportions of a superalloy containing a gamma prime phase, and fusing the powders locally without diffusion to define the shape of a part of the article such that the materials of the distinct metal powders remain substantially chemically segregated forming regions of different chemical composition. The method further includes repeating the forming and fusing until the derived article is formed, and heat treating the finished article such that at least one of the distinct separate materials diffuses to form a gamma prime phase containing superalloy with the other.

Abstract: Methods of additive manufacturing a superalloy component are disclosed. In one method a powder bed of superalloy powder is selectively scanned with a focused laser beam in a line-by-line manner; and the spacing between adjacent scan lines is no more than twice the layer thickness being formed. In another method a compressive stress treatment is applied to the surface of the final component prior to separation of said component from the substrate. In a further method a superalloy component is formed on a substrate and the method includes Hot Isostatic Processing of the component wherein the mass of the substrate is reduced prior to the Hot Isostatic Processing. The methods may be combined in a multi-step process.

Abstract: Apparatus is for additive layer manufacturing of an article from a material which can be rendered solid locally by application of a focused beam of laser radiation at a planar focal plane. The apparatus includes at least two laser beams, respective scanners for each laser beam for scanning the respective laser beams over a planar field, and a support movable stepwise to allow successive manufacturing layer cycles and for supporting material within the field. The entire planar field is common to each scanner and at least one scanner is tilted with respect to the planar field, and the at least one scanner is provided with a lens arranged to generate a focal plane tilted with respect to that scanner.
