Abstracts of Topic-Specified Collaborative Research Projects
1. Establishment of thermal expansion tuning method by using giant negative thermal expansion materials

Representative: Masaki Azuma

There is a growing concern about displacement caused by thermal expansion, which is a critical issue in high-precision devices and equipment, such as optical devices, semiconductor manufacturing equipment, and space vehicles. Composite of resin and giant negative thermal expansion materials stemming from charge, orbital and spin degree of freedom of solid materials will be developed.

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. Development of structural design method considering effects of repetitive loadings and oscillations
Representative: Daiki Sato

It has been known that there is a high possibility of a major Nankai Trough earthquake occurring in the future. A long-period seismic event such as Nankai Trough earthquake will cause tall buildings to oscillate for several times. As building safety technology, dampers are used in passive controlled buildings and seismic isolated building to dissipate earthquake energy. However, several repetitive loadings and oscillations affect damper performance. Aiming to develop advanced structural design of buildings, this research project experimentally and analytically examines damper performance, and the findings are incorporated in the analysis of building response.

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: Hidenori Hiramatsu

This is not only important but also timely to develop new functionalities with abundant element systems. The functionalities that should be targeted mainly include electronics device functionalities. Bulk synthesis and film growth study, structural, electronic and magnetic characterization, and theoretical study are all relevant for the present project.
