  • Method for producing microcapsules or beads
    Patent number: 11198106
    Abstract: An object of the invention is to provide a method for producing a capsule or microbead having high encapsulation efficiency of an encapsulated substance, high production efficiency, and high versatility. The invention relates to a method for producing a microcapsule or microbead, comprising: a step of disposing a monomer droplet or polymer droplet containing a substance to be encapsulated, which has a surface coated with a plurality of solid fine particles, on a flat surface; and a step of solidifying the monomer droplet or polymer droplet disposed on the flat surface in a gas phase so as to form an outer shell of a capsule or microbead, thereby forming a region enclosed by the outer shell, wherein the substance is encapsulated in the region.
    Type: Grant

  • Monolithic silicone and method of separation, purification and concentration therewith
    Patent number: 9285300
    Abstract: The present invention provides a monolithic silicone in the form of an aerogel or a xerogel having flexibility and capable of dissolving molecules of a substance. This silicone monolithic body having continuous through passages is synthesized by copolymerizing starting materials of both a bifunctional alkoxysilane and a trifunctional alkoxysilane or tri- or higher functional alkoxysilanes through a sol-gel reaction for forming a Si—O network while causing phase separation.
