Satoshi Kameoka, Professor
0 student voices
The Kameoka Lab conducts fundamental research and materials development on metals and alloys with new structures and functions, based on a metallurgical perspective. The core of its research is the design and preparation of metal and alloy catalysts with excellent catalytic performance, using bulk metals as the starting material. The lab develops processes for creating new catalytic materials by applying activation treatments such as leaching, hydrogen absorption, and oxidation to metals and alloys. It also works on the synthesis and structural analysis of quasicrystal-related materials (hypermaterials), exploring their potential as catalytic materials.

Kenji Tsuda, Professor
0 student voices
The Tsuda Lab analyzes local structures in materials using transmission electron microscopy and nano-sized electron probes. In functional materials, a growing number of cases show unusual properties arising from nanoscale local structures and from crystal or domain interfaces, which makes investigating local crystal structure increasingly important. Using convergent-beam electron diffraction (CBED), in which an electron beam focused to nanometer size is directed at the specimen, the lab was the first in the world to achieve quantitative local crystal structure analysis based on theoretical calculations. Currently, the lab is working on analyzing inhomogeneous structures such as crystal interfaces and nanodomains, using methods that combine CBED with scanning transmission electron microscopy.

Takahiro Yamada, Professor
0 student voices
The Yamada Lab pioneers new inorganic compounds and functional materials and develops new synthesis methods. Most inorganic materials are metals, alloys, and oxides, but inorganic compounds such as nitrides and intermetallic compounds also have high potential as materials. Many multinary inorganic compounds remain undiscovered, and many that are known still have functions that are not fully understood. The lab searches for new compounds, prepares high-purity samples, and uses experiments and theoretical calculations to verify how their properties and functions arise.

Akira Yoshikawa, Professor
0 student voices
The Yoshikawa Lab researches new crystalline materials for high-performance devices that support the safety and security of civil society. Centered on scintillators used in nuclear medicine equipment, security inspection, and resource exploration, the lab covers everything from crystal development through evaluation to device fabrication. It searches for unknown substances among inorganic compounds that combine many elements, and also pursues new synthesis methods. The lab conducts many joint research projects with universities, research institutes, and companies in Japan and abroad, and members have opportunities for overseas training.

Yu Kumagai, Professor
0 student voices
The Kumagai Lab works to understand and discover new functional ceramics through materials informatics, which combines advanced computational techniques with informatics. The lab runs high-throughput calculations on a huge number of substances and applies machine learning to the resulting data. It is also working to clarify how material properties arise, in systems such as two-dimensional materials and rechargeable batteries. The lab is new, established in April 2022.

Hiroshi Masumoto, Professor
0 student voices
The Masumoto Lab researches the development of new intelligent materials that combine multiple material functions. It works with magnetic-dielectric materials that have a multilayer structure of metal and ceramics, and with osteoconductive implant materials made by modifying the surface of titanium. Its most important theme is 'integrated functional materials,' which give a single material two or more functions. To make materials, the lab uses vapor-phase methods such as plasma, sputtering, and chemical vapor deposition (CVD), as well as pressure sintering.

Taichi Murakami, Professor
0 student voices
The Murakami-Higashi Lab studies how to reduce the environmental impact of the processes used to produce basic metal materials, including steel. Its main theme is making smelting, which relies on high-temperature processes, carbon neutral. The lab clarifies how raw materials degrade inside the furnace when iron is made with hydrogen, and searches for ways to suppress that degradation. It also conducts materials processing research, such as manufacturing technologies for porous metals and the development of self-healing materials.

Fumio Narita, Professor
0 student voices
The Narita-Kurita-Wang Lab studies the design of composite materials made by combining multiple materials, and the evaluation of their mechanical properties and functions. Using piezoelectric, magnetostrictive, and ferroelectric materials, the lab builds energy harvesting devices that draw electricity from vibration and temperature. It also works on highly heat-resistant metal matrix composites for lighter aircraft, as well as plant-derived materials. The lab collaborates with sports equipment manufacturers, universities overseas, and aircraft manufacturers.

Naoto Todoroki, Professor
0 student voices
The Todoroki Lab studies catalyst and electrode materials used in water electrolysis, fuel cells, carbon dioxide electrolysis, and similar devices. The performance of these devices depends heavily on the arrangement of atoms and the electronic state at the catalyst surface, and on the interfaces where different materials meet. The lab aims to understand from the fundamentals what happens there and, based on that knowledge, to create new materials for practical use. Its goal is to contribute to realizing a hydrogen society and achieving carbon neutrality.

Shinichi Orimo, Professor
0 student voices
The Orimo Lab studies hydrides for efficiently converting, storing, and transporting energy. Hydrogen bonds with most elements, forming a wide variety of materials, including metal and alloy hydrides and complex hydrides. Drawing on its research infrastructure for synthesizing, evaluating, and analyzing these hydrides, the lab pursues functional design and fundamental science of high-density hydrogen storage materials and fast ion-conducting materials. The field is closely connected to fuel cells and lithium-ion batteries, as well as to electronic properties and superconductivity.
