Properties of processes associated with the glass transition of water are isomorphic to those of other glass-formers
Since its inception in 1979, the Coupling Model have predicted universality of the dynamic processes and their properties in glass-forming materials irrespective of physical structure and chemical composition. The three major dynamic processes are the caged dynamics at early times, the intermediary primitive and the Johari-Goldstein β relaxation, and the terminal structural α relaxation. They are coupled together, and thus their properties are interrelated and universal. Experiments and simulations data of many different classes of glass-forming materials analyzed over the past 45 years and collected in the review, Prog. Mater. Sci.2023, 139, 101130, have verified extensively the prediction of universality of the interrelated properties. In this paper we performed critical tests of the universal interrelated properties of the three processes in water involved in its liquid-glass transition problem. The positive results from the tests show water is no exception. The universal properties found in water have the benefits of solving the glass transition problem of water and resolving the controversies that last over several decades. Controversies instead of solutions in the past were due to failure to include caged dynamics and Johari-Goldstein β relaxation and their linkage to the structural α relaxation of water in interpreting the experimental data.
期刊介绍:
Chemical Physics publishes experimental and theoretical papers on all aspects of chemical physics. In this journal, experiments are related to theory, and in turn theoretical papers are related to present or future experiments. Subjects covered include: spectroscopy and molecular structure, interacting systems, relaxation phenomena, biological systems, materials, fundamental problems in molecular reactivity, molecular quantum theory and statistical mechanics. Computational chemistry studies of routine character are not appropriate for this journal.
