Quasielastic neutron scattering with in situ humidity control: Water dynamics in uranyl fluoride
Abstract
The authors confirm that water vapor pressure is the driving thermodynamic force for the conversion of the anhydrous structure to [(UO2F2)(H2O)]7 ∙ (H2O)4, and they demonstrate the feasibility of extending this approach to aqueous forms of UO2F2+ xH2O. This method has general applicability to systems in which water content itself is a driving variable for structural or dynamical phase transitions.

FIG. 1: Crystal structures of uranyl fluoride. Oxygen is red, fluorine green, and uranium grey. Top: anhydrous uranyl fluoride (UO2F2). The uranyl-centered units are hexagonal bipyramids with the divalent uranyl ion pointing along the c direction. The c axis is inclined 30° from normal to the page in this diagram.more »
