To investigate the roles of nano-particles, fine particles or aerosols on the plants and agricultural system.. Since 2008, our group has been collaborating with researchers from School of Agriculture, as well as from external institutions.

  • (2010-) Development of an aerosol collector/sampler technique for modeling the deposition of particles on to plant leaves

  • (2010-2011) Nanometer structure to on-site detection of pesticides.
    Collaborators: > Plant Ecochemicals Research Center (Eniwa, Hokkaido) and Kanagawa Industrial Technology Center (Ebina, Kanagawa)

  • (2008-) Designing a vegetations/plant-growth chamber with natural sunlight: Modeling and Experiments
  • (2008-) Deposition of submicron particles from the gas-phase onto the leaf surface
    * Model materials: (Black) Carbon, Sulfate/sulphate
