Development of new multi-functional (Tunneling Magneto-Dielectric effect and Tunneling Magneto-Optical effect) materials by metal-ceramic nano-granular films

Message

When metals and ceramics are composited at nanoscale, they exhibit unprecedented　functional properties. We have discovered new multi-functional properties such as the Tunneling Magneto-Dielectric (TMD) effect and the Tunneling Magneto-Optical (TMO) effect. Through interdisciplinary research in magnetic physics, medical engineering, and materials science, we are pioneering a new field of nano-composite thin films with new functions.

Message

We have proposed an atomic diffusion bonding method for bonding wafers of different materials at room temperature using the rearrangement of crystal lattices at the contact interface of thin films. Using this method, we are developing research on new device formation. We are also working on research on functional thin films used in electronic devices using the thin film deposition technology that is the basis of the bonding technique.

Message

Our laboratory specializes in controlling materials and processes in high-temperature, high-pressure environments, including supercritical fluids. As our commitment to fostering a carbon-circular society, we focus on developing hierarchically structured nanocatalysts and designing highly efficient material conversion processes that fully harness the potential of the nanomaterials.

Message

Random atomic structured materials such as amorphous or metallic glass have significantly different properties with those of conventional crystalline alloys and are anticipated to have industrial uses in the next generation. We address an important challenge by controlling the relaxation behavior of glasses to improve their mechanical properties and to contribute to their applications.

Message

Analyzing the interfaces between the electrolyte solutions and the electrodes for lithium secondary batteries, fuel cells, next generation batteries and molecular electronic devices is important for developing electrochemical energy conversion devices. Our present study investigates the behavior of molecules at the interface with In situ Raman spectroscopy and focuses on the dynamical changes in the Raman spectra at different battery conditions.

Message

We are interested in the relationship between nanomechanics in the cell and cellular morphogenesis. We are analyzing how and why disruption of the cellular nanomachines in our body, such as molecular motor proteins and cytoskeletal proteins, leads to human diseases such as neurodegeneration, infertility, and blindness.

Microelectronic fiber based multimodal bio-interface

Message

Our group works on the development of  the unique microelectronic fibers that are integrated with disparate materials and functions. Such fibers can be used as neural interface to probe brain dynamics across its multimodal signaling mechanisms. In addition, we recently weave such fibers into textile as smart clothes for monitoring multimodal physiological signatures from human body.

Elucidation of protein quality control mechanism in the endoplasmic reticulum

Message

Protein folding coupled with disulfide bond formation, that is oxidative protein folding, proceeds mainly in the endoplasmic reticulum (ER). Greater than 20 Protein Disulfide Isomerase family members (PDIs) are conserved in the mammalian ER to catalyze this reaction. However, it remains an important open question how PDIs recognize various substrates and guide their proper folding through disulfide bond formation and isomerization. The goal of this study is to understand how protein homeostasis is maintained in the mammalian ER. To this end, I employ multiple approaches including single-molecule observation by high-speed AFM, NMR/SAXS analyses in solution, X-ray crystal structure analysis, and several biochemical assays. Diabetes and neurodegenerative diseases are caused by impairment of the protein quality control systems in cells, and hence this study will provide molecular insights into the mechanism underlying these diseases.

We have revealed a population of supermassive black holes that have been missed until now, by combining multi-wavelength electromagnetic wave observations. I am also working with historians to search for astronomical phenomena recorded in historical documents. For more information, please visit my website.
