Abstract

We studied a state of solvent water in the glassy dilute glycerol aqueous solutions from a viewpoint of water polyamorphism. We examined the pressure-induced polyamorphic transition of the glassy samples that relates to the transition between the low- and high-density amorphous ices, LDA and HDA. The polyamorphic behavior of the solvent water depends on the solute concentration. The state of solvent water during the polyamorphic transition may be the state that the LDA-like and HDA-like solvent waters coexist. This finding provides insight into the dynamic behavior of aqueous solutions at low temperatures.
