Glass transition-related changes in mole

Glass transition-related changes in molecular mobility below glass transition temperature of freeze-dried formulations, as measured by dielectric spectroscopy and solid state nuclear magnetic resonance

✍ Yoshioka, Sumie (author);Aso, Yukio (author) 📂 Article 📅 2005 🏛 John Wiley and Sons Inc. 🌐 English ⚖ 247 KB

The purpose of this study was to explore why changes in the molecular mobility associated with glass transition, the timescale of which is on the order of 100 s, can be detected by measuring the nuclear magnetic resonance relaxation times that reflect molecular motions on the order of 10 kHz and 1 M
