The dynamics of THF-water mixture in nanoconfinement

Abstract: Understanding the properties of fluids confined to nanometer scale pores is essential to predict and control a wide range of natural and industrial processes. In this proposal we would like to study on OSIRIS the dynamics of tetrahydrofuran (C4H8O, THF) and water mixture in mesoporous silicas with pores of the order 3-nm diameter. At the compositions we would like to study (1:3.3 and 1:17 THF: water) the liquids are miscible at ambient temperature, but sit under a critical point for closed-loop phase separation. By measuring the dynamics of confined aqueous THF solution across a wide temperature range, we will be able to determine whether there is a non-freezable THF layer anchoring to the pore surface. Our hypothesis based on our previous experiment on NIMROD (RB2210033) is that we will see evidence of preferential adsorption - we are excited to confirm this effect from dynamical view. Other properties such as mobilities of molecules, motion types, onset of diffusion, can be understood. We note also that THF-water is a clathrate forming system, and parallel studies are unearthing fascinating confinement effects at lower temperatures.
