Education and Research Activities in the Laboratory

Ceramic materials play a vital role across a wide range of fields, including manufacturing, infrastructure, electronics, energy, medical, and environmental technology. In order to realize a sustainable society, it is essential to develop technologies that minimize the environmental impact of material synthesis, enable efficient production using limited resources and energy, and improve their performances through innovation. Our research group focuses on environmentally friendly ceramics synthesis via liquid-phase processes. We aim to develop novel synthesis methods and to finely tune the functional properties of ceramics for advanced applications such as environmental purification, biomaterials, and chemical sensors. Through these research activities, we aim to nurture researchers and engineers who can take on the challenges of realizing our vision for the future.

Research Themes

  1. Novel liquid-phase synthesis processes for controlling crystal phase, morphology, and orientation (Fig. 1)
  2. Sorbents or ion-exchangers for environmental remediation and resource recovery (Fig. 2)
  3. Upcycled functional materials from used, waste or unused resources
  4. Functional properties of bioceramics by controlling crystallographic properties
