The Process Design Engineering Lab researches and develops functional materials that contribute to energy saving and the SDGs. Until now, developing new materials has meant searching for conditions such as deposition temperature and source material composition by trial and error, which takes a lot of time and effort. The lab is pioneering "process informatics," which analyzes data obtained from experiments, measurements, and computational science using data science (AI) to reduce the number of trials. Its targets are next-generation semiconductors such as nitride semiconductors, and it is developing a simulation technology (eXS2-CVD) that reproduces the entire chemical vapor deposition process in a virtual space. The lab is looking ahead to high-efficiency power conversion devices, deep-ultraviolet lasers, and ultra-high-frequency devices for post-5G/6G communications.

With space plasma as its keyword, the Space Fluid Environment Lab studies a wide range of cosmic fluid environments, from the space around Earth to distant high-energy astronomical objects. Outer space is filled throughout with plasma, an electrically conducting fluid. The effects of solar activity reach the space environment around Earth through plasma, and the behavior of plasma is also the key to understanding spectacular astronomical phenomena. The lab also focuses on developing propulsion technology for spacecraft by controlling plasma.

The Advanced Space Rocket Engineering Lab studies next-generation space propulsion, including electric propulsion devices for satellites and fusion rockets for crewed interplanetary travel. Its subjects range from palm-sized ion engines for small satellites to fusion rocket engines for crewed interplanetary travel. To understand the physical phenomena involved in plasma, the lab pursues two complementary approaches: experiments that measure plasma density and temperature using cavity ring-down spectroscopy and Thomson scattering, and numerical analysis that solves electrons and ions from first principles. The lab also carries out laser astrophysics experiments, which use high-intensity lasers to reproduce astrophysical plasma phenomena on Earth.

The Power Device Engineering Lab studies semiconductor components (power semiconductor devices) that convert electricity efficiently. To expand renewable energy, it is essential not to waste the electricity that is generated, and to use it while keeping the amount generated and the amount used in balance. The field of technology for controlling and using electricity well is called power electronics, and the semiconductor components that handle the control of electricity in its circuits are called power devices. The lab looks ahead to a new power network that will support a low-carbon society.

The Nonequilibrium Plasma Dynamics Lab (Moon Lab) experimentally studies disordered plasma (turbulent plasma) and the mechanisms by which structures form within it. Plasma is a state of matter widespread in the universe, and studying it leads to a better understanding of the natural world and to technological innovation, including in nuclear fusion. Turbulence is thought to play a major role as a mechanism by which plasma escapes (turbulent transport), and understanding plasma turbulence is essential to realizing nuclear fusion. The lab precisely measures fluctuations of various sizes and speeds and analyzes the data to discover new laws.

The lab studies the relationship between the nanostructure and properties of materials by developing new observation and analysis methods using transmission electron microscopy (TEM). The lab specializes in 4D imaging, which combines electron tomography, a method for visualizing nanostructures in three dimensions, with in situ observation of how materials behave during thermal reactions and deformation. The materials it studies range widely, from metallic materials such as steels, aluminum alloys, and nickel alloys to superconducting materials and nanoparticles. Students themselves operate the advanced electron microscopes at the Faculty of Engineering Sciences and the Ultramicroscopy Research Center, and learn observation and analysis techniques.

The Functional Inorganic Materials Engineering Lab aims to create highly functional catalyst materials that give precise control over chemical reactions, by controlling the structure of inorganic materials such as metal nanoparticles, metal oxides, and porous materials at the atomic level. From a chemical engineering perspective, the lab designs catalytic reactions, and also works on developing energy-efficient reaction processes that use special reaction environments such as microwaves and low-temperature plasma. The lab also researches environmental catalysts that remove pollutants emitted by chemical plants, automobiles, and other sources. It aims to put into practical use a reaction process that can build compact, low-cost reactors, as a countermeasure technology for small- and medium-scale sources of VOCs. The lab's website presents it under the name “Einaga-Hojo Lab.”

The Structural Materials Physics Lab studies the relationship between the mechanical properties of crystalline materials such as metals and their internal microstructure. To improve high-temperature structural materials used in power generators and similar applications, the lab investigates the relationship between deformation mechanisms at high temperatures and internal microstructure. The lab uses electron microscopes to directly observe even the arrangement of atoms at grain boundaries, and combines this with computer simulation in its investigations. The lab's website presents it under the name “Mitsuhara Lab.”

The Functional Materials Physics Lab focuses on oxides, among the functional inorganic materials that conduct electricity, store electricity, or emit light. By combining materials with functions such as conducting electrons, conducting ions, and reacting in special ways with gas molecules, the lab works on new gas sensors and secondary batteries. The performance of gas sensors and secondary batteries can be greatly improved by controlling the combination of materials, their shape, size, and composition. The lab invites students to join in developing new gas sensors and secondary batteries that can help solve energy and environmental problems.

The Thermal and Electronic Functional Properties Lab (Ohtaki-Suekuni Lab) conducts experimental research on functional ceramics, including thermoelectric materials. Converting heat into electricity with thermoelectric materials is called thermoelectric power generation, and it is expected to be a technology for recovering electric power from unused waste heat. Aiming for high-performance materials made from low-toxicity, abundant, and inexpensive elements, the lab handles everything itself, from synthesis to property evaluation, for oxides, sulfides, and other compounds. The lab also pursues other research based on free thinking.
