The lab develops catalysts based on inorganic nanomaterials for producing alcohols and ammonia.

The Yamauchi Lab studies electrocatalysts and nanoalloy catalysts made from inorganic nanomaterials, with the aim of realizing a sustainable society. The lab proposes a carbon-neutral energy cycle that circulates electricity from renewable energy through liquid fuels without emitting carbon dioxide, and develops catalysts for it. The lab also uses in situ spectroscopy, which examines the state of a catalyst while a reaction is taking place, as a research method. The results listed on the research page are those up to around 2018.

The tribology lab studies friction, wear, and lubrication, including in hydrogen environments.

The Tribology Lab specializes in tribology, the field that deals with problems of friction, wear, and lubrication. Working with universities, research institutes, and companies in Japan and abroad, the lab tackles both fundamental issues, such as exploring and clarifying the various phenomena that occur at friction surfaces, and applied issues, such as solving practical problems. The lab also studies tribological properties in hydrogen atmospheres. Assistant Professor Hiroyoshi Tanaka aims to improve the performance of machine elements, focusing on rolling contact fatigue of bearings and DLC coatings.

A lab that studies the loss of strength in metallic materials in hydrogen environments.

The Hydrogen Storage Systems Lab studies how the strength and ductility of metallic materials used in hydrogen equipment decrease in hydrogen gas. When hydrogen enters the interior of a metal, a phenomenon called hydrogen embrittlement occurs, lowering strength and ductility. It is an obstacle to the safe design and cost reduction of hydrogen equipment. The lab works on clarifying the mechanism of hydrogen embrittlement, establishing criteria for selecting metallic materials for use in hydrogen gas, and establishing strength design methods for hydrogen equipment. On the lab's website, the lab is introduced under the name "Hydrogen Storage Systems Lab (Matsunaga Lab)."

A lab that studies the strength of minute materials such as thin metal films.

The Metallic Micro/Nano Materials Strength Lab mainly studies metal thin films, with the aim of clarifying the strength of minute metallic materials. The lab evaluates strength experimentally through tensile tests that pull on thin films, fatigue tests that apply repeated loading, and creep tests that apply a sustained load. The lab's website introduces it under the name "Solid Mechanics Lab," together with Professor Shigeru Hamada. The website states that its ultimate goal is to make mechanical structures operate "safely."

A lab that measures and studies the thermophysical properties of high-pressure hydrogen and refrigerants.

The Thermophysical Properties of Hydrogen Mixtures Lab studies the thermophysical properties of fluids such as hydrogen and refrigerants. Kyushu University's researcher information lists research on the thermophysical properties of high-pressure hydrogen, refrigerants, and mixed fluids, as well as the development of micro heat exchange devices, in the profile. The researcher information also includes a link to the website of the "Thermo-Fluid Physics Lab" in the Department of Mechanical Engineering, Faculty of Engineering.

A tribology lab that studies friction, wear, and lubrication, from fundamentals to applications.

The Tribology Lab studies tribology, the field that deals with problems of friction, wear, and lubrication. The lab works with universities, research institutes, and companies in Japan and abroad on challenges ranging from fundamental ones, such as exploring and clarifying phenomena at friction surfaces, to applied ones, such as solving practical problems. Its research themes include friction and wear in hydrogen, rolling contact fatigue of bearings, and DLC coatings. The lab holds the "Tribology Discussion Meeting," inviting speakers from outside the university to give talks.

A materials strength lab that studies the strength of metals used in hydrogen environments.

The lab studies how metallic materials exposed to hydrogen gas are changed by the effects of hydrogen. Hydrogen embrittlement, in which hydrogen enters the interior of a material and reduces its strength and ductility, is an obstacle to the safe design and cost reduction of equipment that uses hydrogen. The lab works on elucidating the mechanisms of hydrogen embrittlement, establishing criteria for selecting metallic materials used in hydrogen gas, and establishing strength design methods for hydrogen equipment. On the lab's website, it is introduced under the name "Hydrogen Storage Systems Lab (Matsunaga Lab)".
