研究の背景 Background


Highly developed our society is supported by a wide variety of materials. On the other hand, there are various problems to be solved such as environment, energy, accelerated aging society and so on. To solve them and to realize the sustainable and environmentally comfortable society, we believe that creation of novel materials, which can work like as a device, is an important key through simple and low environmental impact processes. Thus, the creation and practical application of "multifunctional material" in which various functions are coexisting synergistically in one material is strongly required.

研究の目標 Outcome


Based on the design, control and fusion of materials nano to macroscopic structures for ceramics and metals, we are focusing on fabrication of functional coexistence ceramic-based materials, low-dimensional oxide semiconductor nanostructured materials and so on, and investigating their detailed structures, fundamental properties, functions analysis and mechanisms. Through these researches, we are aiming to create advanced next-generation functional structure materials to solve various problems in our society.
