Research Summary

Coordination nanosheets are ultrathin films of two-dimensional conjugated polymers composed of metal ions and planar organic π ligands. We first reported coordination nanosheets exhibiting metallic properties in 2013. Coordination nanosheets can be synthesized under mild conditions by bottom-up complexation reactions between metal ions and organic molecules. Since it is possible to create a wide variety of chemical and geometric structures leading to various physical properties, chemical properties, and mechanical properties, the ripple effect of coordination nanosheets on science and industry is immeasurable. We will establish high-quality synthesis of novel functional coordination nanosheets, clarify their physical and chemical properties, and create composite systems such as heterolaminates and conjugates to exhibit their unique physical and chemical functions and explore applications to electronic, magnetic, and optical devices, as well as energy conversion and storage devices.

Research Summary

We studies quantum circuits based on superconducting qubits that utilize Josephson junctions. Regarding the integration of qubits, we are conducting research on quantum chips that can be mounted on a plane using a pseudo-two-dimensional qubit coupling network that we have developed. We are also conducting research on quantum information processing using superconducting Kerr parametric oscillators (KPOs) as bosonic qubits. We generated a cat state with KPO, evaluated the fidelity using a quantum tomography, and succeeded in manipulating a 1-bit gate. In the future, we will proceed with experiments on 2-bit gates and autonomous error correction in KPO. We are also conducting research on the initialization of superconducting qubits. In a quantum optical circuit using a new superconducting artificial atom with a resonator and superstrong coupling, we succeeded in simultaneously exciting two atoms with a single photon.

SDGs Initiatives

Research Summary

Supramolecular chemistry deals with complexes and aggregates of molecules and ions that are formed spontaneously through relatively weak bonds and interactions other than covalent bonds. The structure and function of supramolecules are programmed in the process of self-organization of the constituent molecules and ions, and so supramolecular chemistry is creating a major trend in molecular systems chemistry based on precise design.
In our laboratory, we are working to create supramolecular metal complexes with new structures, properties, reactivity, and functions by utilizing the properties of precisely designed organic ligands and metal elements. Specifically, we are synthesizing, polymerizing, and asymmetrically inducing multi-element metal ion clusters centered on a carbon or a nitrogen atom that we have developed ourselves, and are using highly phosphorescent clusters for photobioanalysis of living cells and highly reactive clusters for catalytic reactions. In addition, we are exploring methods for asymmetric induction and configuration stabilization of metal complexes that have chirality only at the metal center.

Research Summary

Space that lies outward from the terrestrial surface is the frontier to be developed for expanding human activities. In order for the humans to push out this frontier beyond Lunar and Martian space, spacecrafts and space structures with higher performance or efficiency is to be sought. Space and Lunar structures with new, innovative concepts have been investigated in the Laboratory. These include deployable and/or inflatable structures (expansion structures operated by internal gas), that are highly suitable for space or Lunar structures from logistic and efficiency aspects. Current activities of the Lab include innovative inflatable habits for human activities on Lunar surface.

SDGs Initiatives

Research Summary

I have been involved with CV/CG, and XR technologies realizing innovative applications based on high-speed vision. The performance of a system is limited by the lack of even a single component of input, processing, and output. Hence, I aim to build systems that far exceed conventional performance by comprehensively designing sensing, algorithms, and displays based on mathematics, physics, and the output destination system, the human. So far, I have realized high-speed measurement system for 3D shape, motion, texture, and material, and new visual media expressions such as dynamic projection mapping.

SDGs Initiatives

Research Summary

Aging is a universal phenomenon observed across a wide range of species, yet its patterns are complex and highly diverse. Our laboratory aims to elucidate the molecular mechanisms of aging, establish objective evaluation methods, and explore strategies for aging regulation.
We focus particularly on acquired (post-developmental) control of aging, investigating not only the epigenome but also metabolism, gene expression, and peptides to understand temporal molecular changes at the cellular and organ levels. In human studies, we integrate molecular biomarkers with multimodal indicators and AI-based analytics to develop objective assessments of aging and interventions through diet, medicine, and genome editing. We are broadly interested in defining aging at the molecular level across diverse species and exploring conserved principles of aging modulation.

Research Keywords

SDGs Initiatives

Research Summary

I am developing IoT-oriented manufacturing technology by introducing the mass separation technique using ion beams. This study will help us to realise the ultimate fabrication process ruled on periodic law. The mass separators can principally control ionic weights determined by periodic law and the existence of isotopes. Our original mass separator can be installed in the stream of ion beams and selected elements from the metallic solution ion source. This technique can revolutionize the materials driven fabrication process to the periodic driven fabrication process. I believe the realization of our project goals will represent a kind of revolution for academic and industrial studies in this area.
