Abstract: The disclosure discloses a method for producing α-calcium sulfate hemihydrate whiskers by using fermentation broth for producing lactic acid with a calcium salt method as a raw material and synchronously recovering a lactic acid monomer. The method comprises the following steps: 1) after fermentation of lactic acid is ended, heating fermentation broth; 2) stirring, and adding sulfuric acid for reaction; 3) after the reaction is ended, filtering and collecting a solid part, namely α-calcium sulfite hemihydrate whiskers, and collecting a liquid part, namely a free lactic acid solution containing the lactic acid monomer; and 4) washing and drying the obtained α-calcium sulfate hemihydrate whiskers to obtain a α-calcium sulfate hemihydrate whisker finished product, filtering and concentrating the obtained free lactic acid solution to obtain a lactic acid crude product, and refining the lactic acid crude product to obtain a high-purity lactic acid monomer. The disclosure can replace the efficient separation of lactic acid in production of lactic acid with the existing calcium salt method and high value-added transformation of a calcium sulfite byproduct, thereby significantly reducing the refining cost of lactic acid and formation of wastes and facilitating improvement of lactic acid production quality and simplification of a post-extraction process technology.

Abstract: Systems, devices, and techniques for manufacturing a crystalline material (e.g., large crystal material) through the solid state conversion of a polycrystalline material are described. A device may be configured to concurrently heat a volume of ribbon, such as an alumina ribbon, using multiple heat sources. For example, a first heat source may heat a first volume of the ribbon and a second heat source may concurrently heat a second volume, for example, within the first volume, where the ribbon may comprise polycrystalline material. The concurrent heating may drive grain growth in the polycrystalline material in at least the second volume, which may convert the polycrystalline material to crystalline material having one or more grains that are larger than one or more grains of the polycrystalline material. The processed ribbon may include a large crystal material or a single crystal material.

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). Also disclosed is a combination of at least two types of monodisperse particles, where each type is a plurality of monodisperse particles having a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology; and where the types of monodisperse particles differ from one another by composition, by size, or by morphology. In a preferred embodiment, the types of monodisperse particles have the same composition but different morphologies. Methods of making and methods of using the monodisperse particles are disclosed.
