Profile My field of study is colloid and surface chemistry, focusing on organized molecular assemblies of surfactants. I have been conducting research to develop environmentally friendly functional materials by controlling the microstructure of substances through a novel preparation process in which various molecular assemblies such as micelle, emulsion, vesicle, and Langmuir-Blodgett film are applied as templates to fabricate specific nanostructures.
Research Field(Keyword & Summary)
  1. (1) Development of preparation process for inorganic ultrathin films with controlled microstructure

    Various inorganic ultrathin films with controlled microstructures are prepared using organized molecular assemblies as templates, aiming to apply them to dye-sensitized solar cells and photocatalysts.

  2. (2) Application of novel emulsification method in the subcritical temperature region

    For a novel emulsification method using soft hydrophilic nanoparticles instead of surfactants, stability of the emulsions in the subcritical temperature region and applicability to the hydrothermal synthesis are studied.
