Understanding Structural Changes in Amorphous Solid Water (ASW) on Heating

Abstract: This experiment will establish the structural changes that occur in Amorphous Solid Water (ASW) prior to the process of pore collapse or crystallisation. We will study the temperature and temporal evolution of this metastable condensed-matter material, particularly in an astrophysical context, looking at how the ice expands and ice surface rearranges. The experiment exploits the unique Q-range capabilities of NIMROD, capable of determining both the micro- and meso-scale structure of samples concurrently. The results will be of importance in understanding the properties of ASW, the most commonly encountered form of water in the universe, and how the ice expansion at low temperatures impacts on the chemistry and physics that can be occurring during planet and star formation.
