  • Patent number: 9707183
    Abstract: A one-step method for fabricating solidified particles from all-aqueous emulsion droplets involves solidification and drying of the droplets by osmosis. According to this method the fabrication of solidified particles is induced by implementing a high osmotic pressure gradient between the internal phase and external phase of the all-aqueous emulsion. The resultant extraction of water leads to solidification of the emulsion droplets. This approach provides mild conditions for encapsulating bioactive ingredients or other delicate components to conveniently fabricate bio- and cyto-compatible particles because it does not involve the introduction of external energy used in conventional drying. Such conventional external energy inputs are time-consuming, so the method is more efficient.

  • Publication number: 20140243483
    Abstract: Described herein are copolymers constructed from chiral, non-racemic monomers, which self-assemble to photonic crystals. The difficulty of incorporating chiral elements into photonic crystals has limited the ability to generate unique bandstructures for different circular polarizations of light. The materials and methods described herein relate to easily, predictably fabricating chiral photonic crystals having desirable optical properties.

  • Publication number: 20140228525
    Abstract: This invention relates to a rubber composition being excellent in the low heat buildup and fracture properties (resistance to crack growth). and more particularly to a rubber composition, characterized by compounding 10-100 parts by mass of an inorganic filler and/or carbon black based on 100 parts by mass of a rubber component including not less than 10 mass % of a modified conjugated diene-based polymer having a cis-1,4 bond content of not less than 90% and a vinyl bond content of not more than 1.2% and a primary amino group. In this case, the modified conjugated diene-based polymer is obtained by (1) reacting the predetermined conjugated diene-based polymer having an active terminal with a compound having two or more predetermined functional groups and (2) further reacting the resulting product with a compound having a primary amino group.

    Abstract: A method of producing the high molecular weight polycarbodiimide comprises the steps of providing an isocyanate component comprising toluene diisocyanate (TDI), a carbodiimidization catalyst, and a first solvent. The method further comprises the step of polymerizing the isocyanate component in the first solvent and in the presence of the carbodiimidization catalyst to produce a reaction mixture including at least one carbodiimide compound and the first solvent. In addition, the method comprises the step of combining a second solvent and the reaction mixture. Finally, the method comprises the step of polymerizing the at least one carbodiimide compound for a second period of time in the first and second solvents and in the presence of the carbodiimidization catalyst to produce the high molecular weight polycarbodiimide.
