Abstracts of Topic-Specified Collaborative Research Projects

1.Processing, Structures, and Functions of Engineering Ceramics

Representative: Fumihiro Wakai

Ceramics are used in many industrial applications due to light-weight and excellent mechanical properties. The advances in theory and technology are necessary for developing new materials, improve properties and reliabilities through better processing and microstructural control. The research will be performed to advance microstructural analysis, experiments, simulations and theories in multi-scale: atomic, nano, micro and macro scales.

2.Elucidation and design of material functionalities based on computational science 

Representative: Fumiyasu Oba

It is essential to investigate the atomistic and electronic structures of materials for accurate understanding and design as material functionalities originate from these microscopic structures. This project aims at elucidating the relationship between the structures and functionalities in diverse materials for electronics, ionics, catalysts, and so on, as well as magnetic and structural materials, using advanced computational approaches such as first-principles calculations. In conjunction with experimental techniques such as spectroscopy and electron microscopy, we try to obtain and utilize information at the atomistic and electronic level for the design of novel materials.

3. Enhancement of earthquake-resistant technology based on multi-degrees-of-freedom experiment
Representative: Satoshi Yamada

Recently enhanced earthquake-resistant technologies are developed including base-isolated technology and passive control technology. High earthquake-resistant performance is already utilized in many buildings by those technology. However, those technologies are supported by the experiment in which specimens are basically subjected in-plane behavior. Existing buildings have three-dimensional shape and also earthquake acts on buildings as three-dimensional external force. In this research, enhancement of earthquake-resistant technology based on the experiments which reproduces complicated stress condition of structural components under real earthquake is studied.

4.Development of unusual atomic structures in inorganic materials and related new functionalities 
Representative: Toshio Kamiya

Chemical bonds in inorganic materials contain large contributions of covalent bonds with short-range interaction and ionic bonds with long-range interaction, and thus there are many inorganic crystals that have very long periodic structures in 0 – 3 dimensions. It is also expected that artificial control of ionic arrangements will alter local electrostatic potential largely, and thus leads to developing new functionalities. Further, recent works have revealed that strong iconicity is the origin of large mobility in amorphous oxide semiconductors. These imply that the utilization and control of these unusual atomic structures will lead to development of new functional materials and devices. In this project, we will develop new materials and functionalities by designing, controlling, and employing such unusual structures in inorganic materials. The scope of the research project includes materials design, structure characterization, property measurements, development of new devices and applications, and so on.

5. Development of New Functionalities in Abundant Element Materials

Representative: Hideo Hosono

We are pleased to call for abstracts of MSL Collaborative Research Projects on “Development of New Functionalities in Abundant Element Materials”. It is not only important but also timely to develop new functionalities with abundant element systems. The functionalities that should be targeted include electronics and ionics device functionalities and catalytic activities. Bulk synthesis and film growth study, structural, electronic and magnetic characterization, and theoretical study are all relevant for the present project.
