Abstracts of Topic-Specified Collaborative Research Projects

1. Development of novel negative thermal expansion materials by manipulation of multiple orders

Representative: Masaki Azuma

There is a growing concern about the deviation of positioning owing to thermal expansion of structure materials in the fields of advanced electric devices such as power semiconductors and 3D-ICs and energy materials for thermopower and electric fuel cells. Control of thermal expansion is indispensable for the break-though. Our goal is the establishment of thermal expansion control technique through the development of novel giant negative thermal expansion materials by utilizing the charge, orbital, spin and phonon degrees of freedom in solids and the manipulations of these orderings as well as the understanding of thermodynamics of the materials.

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

Representative: Fumiyasu Oba

It is essential to investigate the atomistic and electronic structures of materials for their understanding and design as material functionalities originate from these microscopic structures. This project aims at elucidating the relationship between the structures and functionalities in electronic materials using computational approaches such as first-principles calculations and data-science approaches. 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 life innovation materials 
Representative: Toshio Kamiya

Laboratory for Materials and Structures (MSL) has conducted a trans-university joint project for developing life innovation materials, which will contribute to resolve the current social issues such as energy, resources, environment, and medical, and consequently provide sustainable and comfortable life to us. For this purpose, MSL has developed original technology and materials by utilizing unconventional structures and functions in inorganic and metal materials. In this project, we will develop new materials and devices that will contribute to developing such life innovation materials by combining the MSL’s materials & technology with other proposed ideas.

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.
