  • Publication number: 20220105047
    Abstract: The present invention relates to a microcapsule composition in which polydopamine-coated calcium carbonate microspheres are encapsulated by forming an alginate gel on the surface of a spheroid conjugated thereto, and a method of preparing the same, and it is confirmed that according to the method of preparing the microcapsule, the drug or physiologically active material was individually microencapsulated by gradually forming an alginate gel on the surface of the spheroid containing the drug or physiologically active material, a drug or a bioactive material is placed in the center of a capsule in a very simple way, and a capsule of a very small size can be manufactured in a short time compared to the conventional encapsulation method by adjusting the size of the capsule.

  • Patent number: 10384947
    Abstract: A method for preparing a thin or thick film, including the aligning non-spherical seed crystals on a flat portion of at least one surface of the substrate such that an a-axis, a b-axis, and/or a c-axis are oriented according to a certain rule; and exposing the aligned seed crystals to a solution for enabling the growth of the seed crystals to thereby form and grow a film from the seed crystals using a secondary growing technique.

  • Patent number: 9994442
    Abstract: Provided is a method of arranging particles on a substrate, the method including: (a) preparing a substrate, a surface of which has depressions or projections capable of fixing the positions and/or orientations of one or more particles; and (b) placing the particles on the substrate and applying a physical pressure to the particles so that a portion or the whole of each particle is inserted in each of pores defined by the depressions or the projections. Provided is also a method of arranging particles on a substrate, the method including: (a) preparing a substrate, at least a surface portion of which has adhesive property; and (b) placing particles, which do not have flat facets but curved surfaces, on the substrate and applying a physical pressure to the particles so that the particles are immobilized on adhesive surface portions of the substrate.

  • Patent number: 9938637
    Abstract: Provided are a method for preparing a thin film or a thick film, including: a first step of providing a porous substrate capable of supplying silicon; a second step of applying zeolite seed crystals onto the surface of the porous substrate; a third step of coating the seed crystals-applied porous substrate with an aqueous solution containing a structure-directing agent; and a fourth step of forming and growing a film from the seed crystals by the secondary growth above a temperature at which moisture inside the seed crystals-applied porous substrate prepared in the third step can form steam, and a film prepared by the method. The film manufacturing method of the present invention is a simple manufacturing process, and thus has high reproducibility and high throughput. Since a synthetic gel is not used and a solution is used, the unnecessary consumption of materials, environmental pollution, and waste of a synthetic gel can be prevented while not necessitating drying and washing of a film.

  • Patent number: 9889438
    Abstract: The present disclosure relates to a preparing method of a zeolite core/silica zeolite shell composite, which includes adding a zeolite seed crystal into a gel solution containing a silicon-source compound, a structure directing agent and a fluorine anion-source compound, and then, crystallizing the gel solution for growing a silica zeolite shell containing a crystal structure which is coherent with that of the zeolite seed crystal; a zeolite core/silica zeolite shell composite prepared by the preparing method above; and catalytic use of the zeolite core/silica zeolite shell composite.

  • Patent number: 9695055
    Abstract: A synthetic gel for crystal growth, which induces only secondary growth from the surface of a silicalite-1 or zeolite beta seed crystal and cannot induce crystal nucleation in the synthetic gel for crystal growth or on the surface of the seed crystal. The synthetic gel contains fumed silica, tetraethylammonium hydroxide (TEAOH), [(NH4)2SiF6], KOH, and H2O, or contains tetraethylorthosilicate (TEOS), tetraethylammonium hydroxide (TEAOH), hydrogen fluoride, and H2O.

  • Patent number: 9181085
    Abstract: Provided is method of preparing a printed matter with a printed array of particles, the method including: (a) preparing a template, a surface of which has depressions or projections capable of fixing the positions and/or orientations of one or more particles; (b) placing the particles on the template and applying a physical pressure to the particles so that a portion or the whole of each particle is inserted in each of pores defined by the depressions or the projections to form a particle array; and (c) contacting the template having thereon the particle array to a printing substrate so that the particle array is transferred to the printing substrate.

  • Publication number: 20150218006
    Abstract: A substrate, at least one surface of which is partially or entirely flat, the substrate having: a substrate molded from first substrate-forming particles; second substrate-forming particles partially or entirely filled into first pores which are formed by the first substrate-forming particles on at least one surface of the substrate; and a polymer partially or entirely filled into second pores remaining in a region in which the second substrate-forming particles are filled. Also disclosed is a method for preparing a thin or thick film, including the aligning non-spherical seed crystals on a flat portion of at least one surface of the substrate such that an a-axis, a b-axis, and/or a c-axis are oriented according to a certain rule; and exposing the aligned seed crystals to a solution for enabling the growth of the seed crystals to thereby form and grow a film from the seed crystals using a secondary growing technique.
