Region of Research

  As environmental and energy problems become more serious on a global scale, we are engaged in research and development of green process technologies that greatly reduce the environmental load. In particular, we are focusing on nano- and micro- particles, which work as the functional elements, and are developing their bottom-up synthesis methods and methodologies for assembling them as building blocks in the desired two-dimensional and three-dimensional shapes. In addition, the green process technologies developed in this research field are used to create materials and devices related to the environment and energy field.

Current Research Subjects

  • Green syntheses of nano- and micro- particles
  • 2D&3D Green AM technologies of nano- and micro- particles
