A nano-scale free volume perspective on the glass transition of supercooled water in confinement

A nano-scale free volume perspective on the glass transition of supercooled water in confinement

We employ positron annihilation lifetime spectroscopy (PALS) to measure the temperature dependent fluctuations in a local free volume of water confined in a variety of mesoporous materials with different pore sizes and morphologies. We demonstrate that this unconventional approach can be used to pro...
