Content of research
Based on the hierarchical structure design and control concept, the Department of Advanced Hard Materials 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. 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.
