Keitaro Hitomi, Professor

The Hitomi-Nogami Lab studies sensors for using radiation in medicine and engineering. People are surrounded by radiation from space, food, and the ground, but it cannot be perceived by the human senses. To "see" radiation, the lab works on developing sensors that detect gamma rays in particular. Centered on making things, which is fundamental to engineering, the lab grows semiconductor crystals with its own hands and finishes them into sensors.

The lab studies technologies for separating and extracting nuclides from the high-level radioactive liquid waste generated when spent nuclear fuel is reprocessed. Sorting "nuclear waste" and recovering the valuable components is thought to reduce the volume of radioactive waste and lower its toxicity. The lab is also studying the use of the separated radioisotopes (RIs) as raw materials for radiopharmaceuticals used in cancer treatment. The lab aims to reduce environmental burden while using resources and energy efficiently.

The lab investigates atomic-scale lattice defects that form inside materials. Using methods such as three-dimensional atom probe, transmission electron microscopy, and positron annihilation, the lab studies defects in crystals. Research topics listed for the faculty members include analysis of lattice defects in reactor pressure vessel steel that has suffered neutron damage, and irradiation effects on fusion reactor materials. The lab is also introduced as the Materials Irradiation Engineering research division of the Institute for Materials Research.

The lab researches and develops "materials for extreme environments," which are key to realizing fusion reactors. A fusion reactor has a complex extreme environment in which high temperature, high pressure, and radiation overlap, and this is the wall standing in the way of its realization. The lab creates nano-oxide-particle dispersion strengthened alloys that withstand high temperature and radiation, and evaluates their properties with state-of-the-art equipment. The lab is building a materials engineering foundation that can contribute not only to fusion reactors but also to the safety of nuclear power plants.

Eiji Akiyama, Professor

The Akiyama-Koyama Lab studies hydrogen embrittlement in structural materials used in buildings, automobiles, nuclear power, and more. When hydrogen enters a metal under stress, a type of fracture known as hydrogen embrittlement occurs. The lab investigates how hydrogen enters metals through corrosion and how it behaves inside them, in order to clarify the mechanisms of fracture. Based on these findings, the lab works on methods for evaluating hydrogen embrittlement and on developing materials that resist environments such as corrosive ones.

Dai Aoki, Professor

The Aoki-Miyake Lab studies the physics of compounds containing actinide elements such as uranium, as well as rare-earth elements. The lab creates new materials and explores the unprecedented quantum properties that emerge in them. In these materials, electrons interact strongly with one another, giving rise to a state known as a heavy-fermion system, in which electrons behave as if they were very heavy. The lab handles everything in-house, from growing crystals to measurements under extreme conditions such as ultralow temperatures, high magnetic fields, and high pressure.

Akira Kirishima, Professor

The Kirishima Lab studies the chemistry of the nuclear fuel cycle used in nuclear power. After nuclear fuel is burned in a reactor, radioactive materials and unused uranium remain. By capturing the chemical behavior of radionuclides in aqueous (wet) and non-aqueous (dry) systems, the lab develops recycling methods that generate little waste. The lab is also investigating how radionuclides move in the groundwater environment after treatment and disposal.

Atsuki Terakawa, Professor

The Terakawa Lab conducts research using charged-particle beams from a large cyclotron accelerator. It works on advancing particle beam therapy, which concentrates the dose on the cancer, and boron neutron capture therapy (BNCT), which treats cancer cells selectively. The lab also pursues PIXE analysis, which identifies elements from the X-rays emitted when a low-energy proton beam strikes a sample. In collaboration with researchers in medicine, pharmacy, and veterinary medicine, the lab also conducts basic research combining proton therapy with new anticancer drugs.

Atsushi Okamoto, Professor

The Okamoto-Oyanagi Lab reads the reactions and mass transport that take place inside the Earth from rocks, which serve as a recording medium. It combines field surveys, reaction experiments that recreate conditions in the Earth's interior, and the latest analytical techniques. The lab takes on questions about the interplay of the geosphere, hydrosphere, and biosphere, as well as the unsolved problems of crustal fluids and how earthquakes occur. Building on this understanding, the lab is advancing evaluation and prediction aimed at the effective use of new mineral resources and the Earth's energy.

Mei-Fang Chien, Associate Professor

The Chien-Han Lab studies living organisms, including microorganisms, and the environments they inhabit, to deepen understanding of both. It aims to develop and put into practical use biological (bio) environmental technologies that contribute to a sustainable society. The lab clarifies how plants and microorganisms remove toxic metals and proposes environmental remediation processes. Toward a society in which resources circulate, it also works on recovering metals through the action of living organisms.
