Motoyuki Murashima, Associate Professor
0 student voices
The Murashima Lab belongs to the Nano-Interface Control Engineering field of the Department of Finemechanics, Graduate School of Engineering, and conducts research in tribology, which deals with friction and wear on surfaces where machine parts rub against each other. The lab has studied the relationship between tribofilms, which form through friction from additives in lubricating oil, and DLC films, which offer excellent low friction and wear resistance. It is now developing technology to stably carry microorganisms on the surfaces of machine materials, in order to reduce friction and improve wear resistance. The lab's website is published jointly with the Adachi-Kuriyagawa Lab as the "Adachi-Kuriyagawa / Murashima Lab" site.
Makoto Shimizu, Associate Professor

The Shimizu Lab studies new energy conversion technologies for extracting and using energy without waste. It aims at the effective use of new energy sources such as solar and geothermal energy, and of clean energy such as hydrogen and biofuels. The lab currently works on improving the efficiency of energy systems that use thermal energy, and on fuel cells related to the effective use of hydrogen. In its research on controlling thermal radiation wavelength by wavelength, the lab works on power generation that produces electricity from heat, cooling of electronic devices, energy-saving window glass, and more.
Masaya Shigeta, Professor

The Shigeta-Sugimoto Lab studies high-energy fluid processes that use plasmas hotter than 10,000 degrees. Its targets include making and processing new materials, and rendering hazardous substances that are hard to decompose harmless. For phenomena that are hot, dazzlingly bright, complex, and impossible to investigate with conventional methods, the lab develops new techniques to visualize them and analyzes the data to unravel them. Based on the knowledge obtained, it aims to solve problems and create new thermal fluid processes.
Tetsushi Biwa, Professor
0 student voices
The Biwa Lab studies thermoacoustic phenomena, in which heat and sound waves convert into each other. Heating gas in a tube generates sound waves, and those sound waves can in turn be used to cool. The lab studies thermoacoustic engines and coolers that have no moving parts, few components, and are easy to assemble and maintain. These technologies can use waste heat and solar energy, and are expected to be used in space, deserts, and the ocean.
Eita Shoji, Associate Professor

The Shoji Lab studies the flow and wetting of complex fluids (soft matter), such as liquids containing nanoparticles. To control complex fluids in processes such as printing and coating, understanding the mechanisms of flow and wetting is essential. Using optical measurement methods the lab developed itself, it captures the shape of thin liquid films ranging from nanometers to micrometers in thickness. It also investigates heat and mass transport in oscillating flows, aiming to lead to new separation technologies.
Takafumi Fukushima, Professor
0 student voices
The Fukushima Lab researches three-dimensional integration (3D-IC) technology, which stacks semiconductor chips vertically. Chips are thinned to a few tens of micrometers, and the upper and lower chips are connected by thin wiring that passes through the silicon. The lab introduces this technology as also being used in the high-capacity memory of GPU modules for generative AI. It also works on applications in medicine and wearables, such as devices that embed chips in flexible substrates.
Kazuhiro Ogawa, Professor
0 student voices
The Ogawa-Saito-He Lab studies the safety and reliability of materials, and conducts research that leads to the development of materials that can be used for long periods at high temperatures. Building ultra-high-efficiency gas turbines requires materials that withstand extremely high temperatures over long periods. The lab is clarifying how nickel-based superalloys, thermal barrier coatings, and C/C composites deteriorate over the years. By systematizing the physical chemistry of fracture, the lab aims to contribute to high-efficiency energy facilities and to lower environmental impact.
Yuji Ichikawa, Associate Professor
0 student voices
The Ichikawa Lab studies the safety and reliability of materials, and conducts research that leads to the development of materials that can be used for long periods at high temperatures. Using cold spray, a coating and repair technology, the lab investigates how particles deform when they adhere. By compressing particles under precisely controlled load and strain rate, it observes how oxide films break and how recrystallization proceeds inside the particles. The lab's website is shared with the labs of Professor Ogawa, Assistant Professor Saito, and Assistant Professor He, and is published under the name "Ogawa-Saito/Ichikawa Lab."
Masayoshi Mizutani, Professor
0 student voices
The Mizutani-Kuji Lab studies machining technologies that create fine structures on material surfaces, and their application to medicine. The lab develops machining methods that combine ultra-precision mechanical processes such as cutting and grinding with ultrasonic vibration or laser irradiation. When laser irradiation changes the shape and composition of a surface, the way the surface interacts with cells and bacteria changes as well. Focusing on this change, the lab is working to create bioimplants with surfaces that are "gentle to cells and strong against bacteria."
Hidemasa Takana, Professor
0 student voices
The Takana-Kaneko Lab studies the behavior of flows under electric and magnetic fields through both experiments and numerical simulation. The lab works with functional fluids such as ionic liquids, plasma flows, and magnetorheological (MR) fluids. It investigates the thermal, flow, and chemical properties that appear when the internal structure of a fluid changes under an electromagnetic field. By clarifying the underlying mechanisms, the lab aims to create seeds of technology for energy and environmental applications and for processes that produce new materials.
