Content of research

Based on the hierarchical structure design and control concept, the Department of Advanced Hard Materials (Sekino Lab.) is aiming to develop functions-harmonized bulk ceramics and metals and/or nanostructured materials and to investigate their fundamental characteristics. To achieve this goal, we are adapting: ceramic-based composites with synergy functions, structure-function harmonized hetero-semiconductor composites, the original methodology for elastic properties measurement/analysis for advanced elasticity-controlled metal-based materials, structures/functions tuning of low-dimensional anisotropic oxide nanomaterials for multiple applications, and nano-hybridizing of unique TiO2 nanotubes for photo-physical-chemical multifunctions. Through these researches, our emphasis is placed on the practical application of developed materials and technologies to solve crucial problems arising in our society.

Current Research Programs

  • 1. Gain of multi-functions for ceramics by low-dimensional anisotropic nanostructure control.
    2. Design and creation of hybrid-ceramics via various advanced fabrication processes.
    3. Elastic properties of biomedical and structural metal-based materials and development of the original method for measuring the elastic properties.
    4. Structure and properties tuning of oxide nanotubes/nanosheets and related-architectures aiming for energy, environmental, device and biomedical applications.
    5. Creation of inorganic-based nanomaterials and hybrids via novel fabrication processes.
    6. Desing and creation of multi-task ceramic-based composites.
