Section / Group

Materials Physics Section

The Materials Physics Section carries out fundamental and applied research on dielectrics, magnetic materials, superconductors, ionic conductors, optical properties, catalytic properties, and other material functions. Research on material properties that are necessary to achieve new devices through the enhancement of properties and the discovery of new functions is also performed.

Computational Fluid Dynamics

We are working on computational fluid dynamics(CFD) to analyze fluid phenomena by computer simulation. In particular, we focus on the CFD of multiphase flow in which gas, liquid, and solid phases coexist and flow while interacting with each other. Multiphase flow is intimately related to crystal growth.  In addition to the simulation method used to analyze the convection, diffusion, and mixing of several kinds of liquid at an interface, we carry out simulation of the interaction between liquid and solid particles and among liquids, bubbles, and particles. We are also involved in experimental research on the development of a method of controlling the movement of disperse phases such as particles and bubbles using vortices in a liquid.

Porous Materials Chemistry

Preparation of porous monoliths by the phase separation method and their applications to HPLC columns
and battery electrodes.

Based on the liquid-phase synthesis utilizing polymerization-induced phase separation, we are developing various porous materials ranging from ceramics, organic polymers to organic-inorganic hybrids. The materials with a controlled porous structure are applied to separation media, adsorbents, catalyst supports and battery electrodes. We aim at revealing the influence of pore property on each functionality by interdisciplinary researches with analytical chemistry, organosynthesis and electrochemistry in order to contribute to the development in energy and environmental fields.

Nanostructure Analysis and Design

Functional properties of various ceramic materials are often related to the atomic structures and electronic states in the lattice mismatch regions such as the surfaces, grain boundaries, and interfaces. We are attempting to develop new functional ceramic materials including new ceramic processing techniques from the viewpoint of controlling the lattice mismatch region using the nanoscale analysis technique of high-resolution transmission electron microscopy.

Materials Design Section

This Section promotes researches of material design with a focus on the microstructures of materials used in environments, electronics, mechanics and energy-related fields. Toward the aim of improving the performance and making major strides in terms of enhancements, the MD performs advanced studies through new compositions, novel composites and nanomaterials from the perspective of two- and three-dimensional and/or nanometer-scaled structures.

Environmental Materials Engineering

Material engineering for environmental preservation can contribute to reduce resources and an energy risk as well as to bring environmental depollution. Especially, our research concerns physics and chemistry of nanocrystals such CeO2 and ZrO2 in automotive exhaust treatment and their reaction dynamics simulation. Our unit has been concerned with an iLIM project( MEXT) as a project leader for these years.

Engineering for Nano-spintronics and Magnetic Materials

Our goal is to pursue the energy conversion via spin currents and to contribute to the construction of an energy-creating and energy-saving society in the future. In particular, we are working on experimental and theoretical studies of spin caloritronics, which explores the physics of the interaction between heat and spin, and on the development of materials and devices for generating spin currents from heat currents to generate electric power. Moreover, we are conducting research and development on the creation of new functional magnetic materials that will contribute to next-generation magnetic recording materials, permanent magnet materials, and spintronic devices.
