摘要

自1979年建立以来,耦合模型预测了玻璃成形材料中动态过程及其性质的普遍性,而不考虑其物理结构和化学成分。三个主要的动力学过程分别是早期笼状动力学、中间原始和Johari-Goldstein β弛豫和末端结构α弛豫。它们是耦合在一起的,因此它们的性质是相互关联和普遍的。在过去的45年里,对许多不同种类的玻璃成型材料的实验和模拟数据进行了分析,并收集在论文中。板牙。Sci. 2023, 139, 101130,广泛地验证了相关性质的普遍性预测。在本文中,我们对其液-玻璃过渡问题中涉及的三个过程的普遍相关性质进行了关键测试。测试的阳性结果表明水也不例外。在水中发现的普遍性质有助于解决水的玻璃化转变问题,并解决持续了几十年的争议。过去的争议是由于在解释实验数据时没有考虑笼化动力学和Johari-Goldstein β弛豫及其与水的结构α弛豫的联系。

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.
