[1F01【招待講演】]Utilization of vacuum science and technology in response to societal needs
*Akiko N. Itakura1 (1. National Institute for Materials Science)
At national research institutes like NIMS, researchers pursue projects with long-term perspectives, while keeping in mind the eventual need for social impact. My work in surface science, especially on gas-solid interactions, relies heavily on vacuum technology. Post-2001, we developed gas sensors using surface stress for air detection of hazardous substances, adapting methods from DNA and biomolecular sensing. As research advanced, our focus shifted to hydrogen sensing in metals, leading to the development of an Operando Hydrogen Microscope to visualize hydrogen distribution using electron-stimulated desorption. With the rise of renewable energy and hydrogen’s growing importance after the 2011 earthquake, these technologies have drawn industry interest. This presentation summarizes our findings on hydrogen permeation in various metals.
