| Research Abstract |
Mixed crystals of crystal capsule structure have been formed by mutual anti-solvent crystallization. One solution is sprayed onto the bulk solution. The mixed crystals were made of aqueous solute (ammonium chloride or glycine) and fatty acid. The structure of the crystals was analyzed by XRD, and it was found that the mixed crystals have two individual crystal patterns of the composed substances. Macroscopic structure was the capsule of aqueous solute crystal surrounded by fatty acid crystals. The long-range structure was also analyzed by SAX of Spring-8, and it was found that the crystal structure of fatty acid was slightly shifted to large structure with ammonium chloride inclusions. The deformation of those capsules was effectively performed by the addition of solvent.
