  • Patent number: 9751758
    Abstract: A method for lattice design via multivalent linkers (LDML) is disclosed that introduces a rationally designed symmetry of connections between particles in order to achieve control over the morphology of their assembly. The method affords the inclusion of different programmable interactions within one linker that allow an assembly of different types of particles. The designed symmetry of connections is preferably provided utilizing DNA encoding. The linkers may include fabricated “patchy” particles, DNA scaffold constructs and Y-shaped DNA linkers, anisotropic particles, which are preferably functionalized with DNA, multimeric protein-DNA complexes, and particles with finite numbers of DNA linkers.

  • Patent number: 9650556
    Abstract: The present disclosure relates to a method of encapsulating microcapsules containing relatively high temperature phase change materials and the microcapsules so produced. The microcapsules are coated with an inorganic binder, film former and an inorganic filler. The microcapsules may include a sacrificial layer that is disposed between the particle and the coating. The microcapsules may also include an inner coating layer, sacrificial layer and outer coating layer. The microcapsules are particularly useful for thermal energy storage in connection with, e.g., heat collected from concentrating solar collectors.

  • Patent number: 9634333
    Abstract: The present invention is directed to improving a catalyst applied to a reaction layer having a structure (PFF structure) in which a polymer electrolyte phase surrounds a periphery of a catalyst with a hydrophilic region interposed therebetween and reducing the amount of catalyst metal particles used. A method for producing a catalyst for a fuel cell, in which a catalyst metal particle is supported on a carrier, includes the steps of: preparing an unmodified catalyst in which a catalyst metal particles is supported on a carrier; and modifying the catalyst metal particle in the unmodified catalyst with at least one type of modifying group selected from a nitric acid group, an amino group, a sulfonic acid group, a hydroxy group, and halogen groups.

  • Patent number: 9622966
    Abstract: A gastroretentive composition comprises a mixture comprising an active ingredient component and an excipient component. The excipient component comprises a first water-soluble reaction product produced from a precursor comprising a vinyl group, and a copolymer of a polyalkylene glycol and a second water-soluble reaction product produced from a precursor comprising a vinyl group. A method of forming the gastroretentive composition comprises the steps of providing the active ingredient component and the excipient component, and mixing the active ingredient component and the excipient component to form a mixture. The mixture is aggregated to form an aggregation that is dry granulated to form a plurality of granules. The plurality of granules is processed to form the gastroretentive composition.

  • Patent number: 9486732
    Abstract: Adsorbent compositions useful in adsorption and separation processes are made using silicone-derived binding agents. The adsorbent compositions are made from crystallite aluminosilicate particles bound with silicone-derived binding agents, and optionally small amounts of a clay binder, to form agglomerated crystallite particles and are calcined to volatilize the organic components associated with the silicone-derived binding agents. The agglomerated crystallite particles have superior pore structures and superior crush strengths at low binder concentrations and exhibit enhanced N2 adsorption rates and capacities when used in air separation processes.
