Ultrafast Intermolecular Dynamics of Nanoconfined Water in Swollen Lipid Cubic Mesophases.

ABSTRACT: Understanding the structure and dynamics of the hydrogen-bond network of water in topologically distinct swollen lipidic mesophases, is fundamental for their application in biomedical, pharmaceutical, and food science fields. Here, a positive and non-linear correlation between water hydrogen-bond dynamics and interfacial water population is uncovered in inverse bicontinuous swollen mesophases across an extended temperature range (298-340 K). Particularly, small-angle X-ray scattering determines the mesophase's structural features, uncovering a temperature-driven re-entrant phenomenon (reappearance) of Pn3¯m$Pn\bar{3}m$ phase upon heating. This topologically rich environment, however, has no detectable impact on the temperature dependence of the intermolecular modes of water, as revealed by
