Momoji Kubo, Professor
0 student voices
The Kubo Lab uses computational science simulations to design systems and materials from theory. Its core is multiscale technology that connects nanoscale chemical reactions, mesoscale microstructures, and macroscale heat and fluid flow. The lab also handles phenomena in which chemical reactions, friction, impact, stress, fluid flow, light, electrons, heat, and electric fields are intricately intertwined, treating them all together. The target fields are wide-ranging, including fuel cells, aerospace equipment, electric vehicles, and semiconductor processes.
Junji Saida, Professor

The Saida Lab studies the mechanism that makes the supercooled liquids of alloys stable, and the nanostructures that form naturally from them. Among alloys, some have supercooled liquids that stay especially stable without solidifying, even below the melting point. This stability is thought to depend heavily on the arrangement of atoms (local structure) that forms within the liquid, and the lab investigates that mechanism. Using this phenomenon, the lab makes materials in which nanostructures self-organize, as in bulk metallic glasses, and evaluates their properties.
Takeshi Seki, Professor

The Seki Lab studies magnetic materials whose structures are controlled at the nanoscale, and the physical phenomena that appear in them. At the nanoscale, magnetic properties based on electron spin are deeply tied to various transport phenomena. Properties that do not show up in macroscopic magnets can be extracted and put to use at this size. Combining thin-film growth techniques with microfabrication, the lab creates materials useful for spintronics and magnetics.
Atsushi Momose, Professor

The Momose Lab aims to develop new measurement methods, with the measurement of X-ray phase as its keyword. Conventional X-ray transmission imaging creates contrast from differences in absorption between materials, so it has lacked sensitivity for objects made of light elements, such as soft tissue in living bodies and soft matter. X-ray phase-contrast imaging, which has attracted attention since the mid-1990s, is a technique that can overcome this weakness, and the lab has been at the forefront of its development. Today, the lab is expanding its applications to the observation of a wide range of materials while also working toward practical uses such as medical diagnostic imaging.
Yuichi Kozawa, Professor

Drawing on its strengths in laser technology and wavefront control, the Kozawa Lab conducts applied research based on the interaction between light and matter. Basic properties of light such as intensity, phase, and polarization are usually spread uniformly across the cross-section of a beam. It has become clear that designing their distribution in space gives rise to new properties that did not exist before. Using such light, the lab is expanding applications to optical imaging, measurement, laser processing, and optical trapping.
Yutaka Sato, Professor
0 student voices
The Sato-Suzuki Lab studies welding and joining processes that bond one material to another. Even materials with excellent properties often lose their microstructure at the joint, and their properties deteriorate. By closely examining the microstructure and properties of joints and joint interfaces and controlling them, the lab aims to establish ways to preserve those excellent properties. The lab covers a variety of welding and joining methods, but puts particular effort into research on friction stir welding.
Naoyuki Nomura, Professor

The Nomura-Zho-Dong Lab studies how to create functional, tailor-made fine particles and apply them to powder metallurgy. By deliberately arranging and "assembling" spherical fine particles of uniform size, the lab aims to create materials with functions that particles alone cannot achieve. The lab is developing fine particles with the freeze-drying pulsated orifice ejection method, and studying composite materials of graphene and carbon nanotubes. The lab also develops ultra-high-temperature heat-resistant materials and low-magnetic medical materials by 3D printing, starting from the production of the powder itself.
Yoshikazu Ohara, Professor
0 student voices
The Ohara-Nagakubo Lab conducts cutting-edge research on non-destructive measurement, using ultrasound to examine the inside of materials. Building on its original technologies in nonlinear ultrasonics, phased arrays, and laser measurement, the lab aims to create measurement techniques that make visible what could not be seen before. Drawing on international joint research, mainly with partners in Europe and the United States, the lab also aims to realize the industrial metaverse, the "digital twin." The lab is the Materials System Measurement field of the Department of Materials System Engineering.
Chaonan Xu, Professor
0 student voices
The Xu-Uchiyama Lab studies "conversion materials" that convert force into light and electricity. The lab invented the "mechanoluminescent material" and the "multi-piezo material," realizing materials that glow with high sensitivity and stability when only a slight mechanical stress is applied. These materials combine strong mechanoluminescence and piezoelectricity, and are attracting international interest as a function based on a new concept. Approaching the problem through both theory and experiment, the lab is pioneering conversion materials that will be useful in a future society of AI and IoT.
Masaya Yamamoto, Professor
0 student voices
The Yamamoto-Kobayashi Lab studies, based on medical polymers, the phenomena that occur at the "interface" where living bodies and materials meet. For regenerative medicine, the lab develops biomaterials for building cell scaffolds and vascular networks. The other pillar is research that examines, at the cellular level, the effects of nano- and microplastics on living organisms.
