| Research Abstract |
In this study, we focused on nano-scale pores (nanopores) towards understanding glass transition. Ortho-positronium lifetime spectroscopy was conducted for investigating size (or size distribution) of nanopores. New methodology developed for analyzing the chemical environment around nanopores by means of positron-age-momentum correlation (AMOC) spectroscopy was successfully applied to glass materials. Furthermore, time-resolved dilatometric experiments were performed to study kinetics of nanopores.
