  • Patent number: 10053798
    Abstract: Methods and systems for manufacturing a tablet are generally provided. Certain embodiments comprise electrodepositing (e.g., electrospinning) a material (e.g., the tablet material, for example, within a fluid) onto a substrate. The substrate can be, for example, an elongated rod. In some such embodiments, after material has been electrodeposited onto the substrate, a die comprising a cavity and the substrate can be moved relative to each other such that the electrodeposited material is at least partially stripped from the substrate and/or at least partially deposited into the cavity of the die. Some embodiments comprise compressing the material in the cavity to form a tablet.

  • Patent number: 9903050
    Abstract: Disclosed are methods that utilize the differences in physical properties between two coating fluids to form core-shell particles or core-shell fibers by coaxial free-surface electrospinning. The methods are able to achieve higher productivity than known methods, and are tunable. Nonwoven fiber mats of electrospun fibers have garnered much scientific and commercial interest in recent years due to their unique properties, such as their high porosity, high surface area and small diameter fibers.

  • Patent number: 9205089
    Abstract: Layer processing for pharmaceuticals, and related systems, methods, and articles are generally described. In some embodiments, ingestible pharmaceutical products (e.g., tablets) can be formed by processing one or more layers containing a pharmaceutically active composition. For example, at least one layer containing a pharmaceutically active composition can be manipulated (e.g., folded, rolled, stacked, etc.) such that the average thickness of the product formed by the manipulation is at least about two times the average thickness of the portions of the layer(s) used to form the product. In some embodiments, after the layer is manipulated, it can be processed (e.g., cut, coated, etc.) to form a final product such as, for example, a tablet.

  • Patent number: 8684189
    Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.

  • Publication number: 20110064936
    Abstract: One aspect of the invention relates to a method for installing coatings of different morphology and function within a single textile membrane. Remarkably, the methods described herein enable one to engineer the properties of a material at the nanoscopic level and produce the material in commercially viable quantities. For example, by simply controlling the flow rate of charged species passing through an electrospun material during spray-assisted Layer-by-Layer (Spray-LbL) deposition, individual fibers within the matrix can be conformally functionalized for ultra-high surface area catalysis, or bridged to form a networked sublayer with complimentary properties.
