Outline

The need for new materials and substances in the energy and environmental fields is increasing for the construction of a sustainable society. In this research, we target negative thermal expansion materials and selective oxidation catalyst materials, both of which are highly desired in industry, and explore new materials by a new method of combined high-throughput synthesis of multi-element compounds from amorphous precursors and machine learning.

Munetoshi Seki	Associate Professor Graduate School of Engineering The University of Tokyo

Outline

We are creating sensor, memory, and computation materials utilizing dipole and spin coupling due to flexoelectricity induced by strain gradient lattice distortion, taking advantage of the versatile physical properties of functional oxides and high crystal structural tolerance due to ionic bonding properties. Aiming to create new functions for oxide materials, we are inspired by biological functionality and actively utilize “thermal fluctuation,” which has usually been considered a “noise,” by using it as an energy source in the environment. We will design and develop innovative low-power-consumption and/or high-sensing materials based on the “stochastic resonance” principle.

Outline

We propose and establish new materials design concept “Phason engineering”, which enables us to introduce local and global tiling deformation into materials through the phason degree of freedom, in addition to conventional materials design methodology. The target materials are 3D metallic and 2D van der Waals quasicrystals(QCs) and approximants(ACs) which are expected to exhibit superior properties impossible for ordinary crystals. In this project, we elucidate the influence of the local/global modification of atomic tiling on the materials properties, and pursue novel and peculiar magnetic, electronic and catalytic properties in the above QCs and ACs.

Outline

Dispersions of nanoparticles that can undergo a phase transition upon electrochemical stimulation are referred to here as ”phase-transition nanofluids”. The phase-transition nanofluids have fluidity and the ability to transfer electrons in response to temperature and are expected to become new thermoelectric material. In the project, we build up the basic science of the material and thermoelectrics.
