The Plasma Applied Science and Engineering Research Group (Hayashi Lab) researches new technologies that apply plasma to medicine, biotechnology, agriculture, and the environment. Because plasma is short-lived, it allows safe and harmless applications without the concern of residual agents, unlike chemicals. The lab develops sterilizers for medical instruments and disinfection devices for agricultural products, and also pursues research on promoting plant growth, killing cancer cells, and activating immune cells.

The Optical Device Engineering Lab studies semiconductor lasers with the goal of opening up a new world of lasers. It aims for leaps that would change conventional assumptions about existing lasers by at least three orders of magnitude, advancing its research with an eye on everything from proposing theory to experimental demonstration and practical use in society. Research themes include a full-color laser that emits red, blue, and green light from a single semiconductor laser and its application to optical tweezers, higher output by arranging many VCSELs, and wavelength-stable lasers for atomic clocks. Because the lab is in its start-up phase, students are also deeply involved in refining research themes and building the experimental environment.

The Solid Mechanics Lab studies the strength of materials used in machines, with the ultimate goal of making mechanical structures operate safely. The safety of a machine is evaluated with the Stress-Strength Model, which compares the applied force (Stress) with the strength of the material (Strength), but many problems remain unsolved on the strength side. The lab therefore examines strength experimentally and analytically from the viewpoint of micro-scale mechanics, and links the results to computer-based analysis methods. While investigating metal fatigue and the effects of hydrogen, the lab also works on solving failure problems in real mechanical systems such as automobiles.

The Fluid Design Lab studies the optimization, robustness enhancement, and intelligentization of fluid machinery by combining fluid engineering with mathematical and data science. The lab also studies the flow inside turbomachinery using optical imaging-based measurement methods such as pressure-sensitive paint, temperature-sensitive paint, and particle image velocimetry. Graduate students (including international students) and undergraduate thesis students receive research supervision.

The Bio-Thermal Engineering Lab conducts research in bioengineering, thermal engineering, and bio-thermal engineering, which involves both. Bioengineering is a discipline that addresses and solves problems in medicine and biology from an engineering perspective. Even in research related to cells and medicine, the foundation of the lab's thinking lies in mechanical engineering, including thermal engineering, and the lab values a mechanical engineering perspective. The lab is most interested in minimally invasive cancer treatment using electrical effects on cells, the biomechanics of tendon, bone, and cartilage, and the open-source design of biology education materials.

The Thermal Energy Conversion Engineering Lab aims for innovative, effective use of thermal energy and conducts research on boiling, evaporation, multiphase flow, and adsorption. The generation, conversion, and transfer of thermal energy, as well as temperature control, are major issues in energy technology, electronics, production technology for new materials, and the analysis of environmental problems and safety. Because advanced, effective use of energy is essential in addressing global warming, the lab conducts research toward solving these problems. The lab belongs to the Thermal Engineering Division of the Department of Mechanical Engineering, Faculty of Engineering, Graduate School of Kyushu University.

The Hydrogen Production Process Lab (Matsumoto Lab) takes "environmental and energy electrochemistry" as its keyword and studies the development and application of functional materials centered on solid materials that conduct protons. A proton is the positive ion of hydrogen. Solids that conduct protons can be used in many hydrogen energy applications, such as fuel cell power generation and hydrogen production by electrolysis. In steam electrolysis, the lab has succeeded in highly efficient steam electrolysis experiments by improving electrode materials and making the electrolyte thinner. The lab is also developing new ion-conducting solids and exploring new phenomena and underlying science hidden in the behavior of ions inside solids.

The Hydrogen-Compatible Materials and Fracture Science Lab studies how hydrogen affects the strength of metallic materials. Hydrogen plays an important role both as an energy carrier and as a chemical raw material, but it can also reduce the strength of metallic materials. To ensure the safety of equipment that uses hydrogen, the lab conducts strength tests of metallic materials in hydrogen environments, based on mechanics of materials. The lab was established through the cooperation of the Department of Mechanical Engineering and the International Institute for Carbon-Neutral Energy Research (WPI-I2CNER).

The Materials Creation Mechanics Lab studies atomic- and nanoscale manufacturing that uses atomic diffusion, in which atoms move within a solid. Materials so small they are invisible to the eye show new functions, such as high strength and unusual conductivity, simply by being made small, but they are difficult to make and have not come into widespread use. The lab is therefore developing new ways to make small materials, such as growing metal nanowires by gathering atoms at targeted locations. The lab also studies the interaction between electrons and atoms using electron microscopy, and develops methods to improve the mechanical properties of metals and ceramics.

The Mechanical Dynamics Lab works to elucidate phenomena related to the motion of machines, such as vibration and waves, and to develop new technologies that use them. With the SDGs in view, the lab works on vibration energy harvesting using new mechanisms and on vibration control that reduces energy costs. Using a new diagnostic technique based on ultrasonic waves, the lab aims to establish the safety and reliability of machines. The targets are not limited to mechanical structures but also include living bodies and food, and the lab actively engages in joint research with companies and contract research.
