Abstract

The structural mechanisms of the transitions between crystalline phases Ih, III, V, VI, and VII, whose stability regions border the liquid phases in the PT phase diagram, are described. The possibility of forming pseudoscalar liquid-crystal (PSLC) states of water during melting of enantiomorphic ice III is discussed. An example of a structural nematic–cholesteric transition in an aqueous solution when a nematic liquid crystal is affected by a helical stationary wave is considered. The importance of studying the structure and properties of hydrogen peroxide aqueous solutions is substantiated.
