Abstract
Water-rock interactions determine how the geochemical cycles revolve from the Earth's surface to the deep interior (large T-P intervals). The underlying mechanisms interweave the fluxes of matter, time, and reactivity between fluid phases and solids. The deformation processes of crustal rocks are also known to be significantly affected by the presence or absence of water, typically with the hydrolytic weakening of quartz, olivine, and other silicate minerals. In fact, fluid-rock interactions mechanistically unfold along their interfaces, developing over a certain thickness within the two phases. Diffraction-limited mid-infrared microspectroscopy was employed to monitor the thermodynamic characteristics of liquid water along a quartz boundary. The hyperspectral Fourier transform infrared data set displayed a very strong distance-dependent signature for water over a 1 ± 0.5 μm thickness, while quartz appears unmodified, which is consistent with recent studies. This unexpected thick interface is tested against the geometry of the inclusion, the chemistry of the occluded liquid (especially pH), and the thermal conditions ranging from room temperature to 155 °C. Throughout this range of physicochemical conditions, the micrometer-thick interface is characterized by a ubiquitous, significant shift in the Gibbs free energy of water inside the interfacial layer. This conclusion suggests that the interface-imprinting phenomenon driving this microthick layer has thermodynamic roots that give rise to specific properties along the quartz-water interface. This finding questions the systematic use of the bulk phase data sets to evaluate how water-rock interactions progress in porous media.

Abstract
Abstract
The Canadian supercritical water-cooled reactor was selected as one of the Generation IV International Forum initiatives for reactor design. It uses supercritical light water as a coolant under operating conditions of 25 MPa (250 bar) and 623–898 K. However, the simulation codes used to assess the performance and safety of such a design depend upon the accuracy of available nuclear data parametrizations, which currently do not include models of light water in the supercritical regime. In this paper, we present a study of supercritical water (SCW) through molecular dynamics simulations. Flexible variants of the TIP4P/2005 and simple point charge models for H2O are assessed to determine their ability to reproduce experimental measurements of SCW properties, and their suitability for the future development of nuclear data parametrizations for thermal neutron scattering from SCW. Planned experiments measuring thermal neutron scattering from SCW to inform nuclear data development are also summarized.
