  • Patent number: 10183968
    Abstract: Methods for preparing lyophilized pellets of biological materials are described. The pellets have a substantially spherical shape and are prepared by freezing droplets of a liquid composition of a desired biological material on a flat, solid surface, in particular, a surface that does not have any cavities, followed by lyophilizing the frozen droplets. These methods are useful for preparing lyophilized pellets having a high concentration of a desired biological material, in particular a therapeutic protein or vaccine, and which have a faster reconstitution time than lyophilized powder cakes prepared in vials.

  • Patent number: 9017810
    Abstract: A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced.

  • Patent number: 8088629
    Abstract: Various methods for forming dyed microspheres are provided. One method includes attaching a hydrophilic dye to chemical groups to form a bubble. The bubble includes the chemical groups surrounding the hydrophilic dye and an aqueous solution. The chemical groups are soluble in aqueous and organic solvents. The method also includes disposing the bubble and a microsphere to be dyed in a solvent such that the bubble is incorporated into the microsphere thereby dyeing the microsphere. Another method includes adsorbing a hydrophilic dye on a surface of a hydrophobic polymer core of a microsphere to be dyed thereby dyeing the microsphere. The method also includes attaching chemical groups to the hydrophilic dye. The chemical groups are soluble in aqueous and organic solvents. The chemical groups attached to the hydrophilic dye form an enclosure surrounding the hydrophilic dye and an aqueous solution.

  • Publication number: 20110277666
    Abstract: This invention describes the encapsulation of and self-assembly of meso (nano) porous silica particles from inorganic an inexpensive silica precursor, sodium silicate. The particles have a well defined shape, high surface area, and high uniformity of the pore size, the properties that are typically found for high quality mesoporous material synthesized from organic silica precursors. The disclosure illustrates a synthesis of hard spheres, discoids, and a mixture comprising discoids, gyroids and fibers, termed as origami.

  • Patent number: 7906567
    Abstract: The present invention provides a method for producing an encapsulated product in which a core substance having an electric charge on its surface is coated with a wall material comprising a polymer as a main component, the production method comprising at least the following steps (1) to (4): (1) a step of adding an ionic polymerizable surfactant A containing an ionic group having the opposite electric charge to the electric charge on the surface of the core substance, a hydrophobic group and a polymerizable group to an aqueous solvent containing the core substance, followed by mixing, thereby adsorbing the ionic polymerizable surfactant A to the surface of the core substance; (2) a step of adding, after said step (1), an ionic polymerizable surfactant B containing an ionic group having the same or opposite electric charge to the electric charge on the surface of the core substance, a hydrophobic group and a polymerizable group, followed by mixing; (3) a step of adding, after said step (2), a hydrophobic monome

  • Patent number: 7875358
    Abstract: A composition for a slurry for manufacture of a building panel includes one or more fillers, one or more binders and water. One or more fillers is an expanded perlite at least partially covered with a film-forming, thermoplastic polymer coating Some embodiments use calcined or uncalcined gypsum as a binder or filler. One embodiment is a building panel that includes a solid matrix of calcium sulfate dihydrate crystals bound to expanded perlite. A method of making the panel includes acquiring expanded perlite and coating it with film-forming, thermoplastic polymer coating. After the expanded perlite is prepared, it is combined with water other optional fillers and one or more binders to form a slurry. The slurry is shaped into a panel and allowed to dry.

  • Patent number: 7875212
    Abstract: Embodiments of the present invention provide polymer matrix nanocomposites reinforced with nano-scale materials such as nanoparticles and carbon nanotubes and methods of fabricating. The nanomaterials are provided within relatively low weight fractions, for example in the range of approximately 0.01 to about 0.4% by weight and distributed within the matrix by a magnetic mixing procedure to provide substantially uniform reinforcement of the nanocomposites. Advantageously, these nanocomposites provide significantly enhanced tensile strength, strain to failure, and fracture toughness over corresponding neat matrices.
