The lab controls the structure of ceramics through liquid-phase synthesis to enhance functions such as environmental remediation.

The Environmentally Friendly Ceramics Lab studies how to control structure, from the arrangement of atoms in crystals to the shape of particles, through liquid-phase synthesis using solutions. It aims to enhance functions such as adsorption and photodecomposition properties, corrosion resistance to water vapor, and electrochemical properties. By examining crystal and surface structures, pore structures, and the coordination states of constituent elements, the lab builds an understanding of the relationship between structure and function from the viewpoint of the synthesis process. The lab's website is shared with the Ishihara 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 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)".

The lab uses electron microscopy to study fuel cell materials at the atomic level.

Professor Junko Matsuda is a faculty member of the Hydrogen Utilization Process Lab and is involved in research that examines fuel cell materials with electron microscopes. The Hydrogen Utilization Process Lab aims to realize a hydrogen energy society centered on fuel cells, which convert energy to generate electricity and heat without combustion. Observation with atomic-resolution high-resolution electron microscopy has become an essential technique in research on a wide variety of fuel cell materials. This site belongs to the lab headed by Distinguished Professor Kazunari Sasaki.

The lab studies gas diffusion layers that improve the power generation performance of fuel cells.

The Kitahara Team of the Fuel Cell System Lab researches gas diffusion layers to improve the performance of fuel cells. The team makes gas diffusion layers coated with a microporous layer (MPL), varying the composition, pore size, porosity, and thickness, and examines the effects on water repellency and on gas and water permeability. The goal is to establish design guidelines for high-performance gas diffusion layers that resist drying out even under low-humidity, unhumidified conditions. This site introduces the research of the Ito Team, the Kitahara Team, and the Nakajima Team together.
