Outline Activities
Kazuhiro Yasuda’s research interests are on radiation effects and microstructure development of nuclear materials and energy materials. His works relates (1)the atomic scale structure of radiation-induced defects in ceramics and metals, and its accumulation process and stability, (2) physical mechanism of radiation damag in ionic and covalent materials, (3) Synergy effects of displacement damage and electronic excitation in ionic and covalent materials, and (4) development of "in-situ" experimental method by using high voltage electron microscope to elucidation of the production and kinetics of point defects.
