“…In addition, an underlying firstorder transition occurs at TK2 = 122.4 K without latent heat as theoretically suggested [34][35][36], above the Kauzmann temperature TK1 =119.8 K transforming Phase 3 into an "ordered" glacial phase by an enthalpy decrease. The specific heat, the transition temperatures, the entropy and enthalpy of various phases are calculated, for the first time, as a function of the temperature and pressure in agreement with many experimental results [1,3,6,7,15,16,19,[54][55][56][57][58][59] by only knowing the glass transition Tg, the melting temperature Tm, and the melting enthalpy Hm.…”

“…The transformation of Ice Ih at 3 kbar when compressed slowly at 100 K, collapses to distorted, tetrahedrally bonded Ice IX while the HDA phase is obtained during a fast compression. These last experiments confirm that HDA and HDG can be a "derailed" state along the ice I to another ice form pathway [59].…”

The classical nucleation equation, applied to two liquids, is completed by an additional enthalpy for solid supercluster formation governing the liquid and glass transformations. This model defines a formation rule of glacial phases, explaining the origin of the first-order transition of water from fragile-to-strong liquids at TLL = 228.5 K, only fixing Tg = 137.1 K. All thermodynamic properties and transitions, even under pressure P, are now predicted in agreement with experiments. The lowest-density liquid is, at once, the glacial phase of fragile and high-density liquids. It is formed at TLL, remains liquid during the first cooling, and gives rise to the glass Phase 3 by heating through a first-order transition without latent heat at TK2 =122.4 K. Medium-range order appears above Tg during the first heating.Phase 3 with its own Kauzmann temperature undergoes the first-order transition at TLL without latent heat and superheats up to Tn+ > Tm.

“…Just to illustrate this point, let us review some examples at different levels of 'complexity'. 4 At the basic, chemical level, deciphering the chemical structure of water, which is of paramount importance for questions such as the elucidation of protein structure, is a matter of great challenge in physical chemistry and an area of active research [19,20]. At the protein level, a big mystery is the presence of "intrinsically disordered" domains in the structure of proteins [21], with different functions attributed to their presence (see, e.g., [22]).…”

“…Galen himself thought highly of Aristotle and Hippocrates: 19 "All these and many other points besides in regard to the aforesaid faculties, the origin of diseases, and the discovery of remedies, were correctly stated first by Hippocrates of all writers whom we know, and were in the second place correctly expounded by Aristotle" (On the Natural Faculties II.4). 20 It is in this context that I would like to briefly move back a few centuries before Galen and mention Erasistratus (c. 304-250 BC), who "was regarded by his followers as a successor to Aristotle and Theophrastus" [62]. Christie, writing on Galen's critical reception of the teachings of Erasistratus, remarked that "the school of the Erasistrians survived until after the time of Galen, who did a great disservice to medical progress by destroying its credibility with rhetoric based on sarcasm and ridicule" [70].…”

The mantra that “the best way to predict the future is to invent it” (attributed to the computer scientist Alan Kay) exemplifies some of the expectations from the technical and innovative sides of biomedical research at present. However, for technical advancements to make real impacts both on patient health and genuine scientific understanding, quite a number of lingering challenges facing the entire spectrum from protein biology all the way to randomized controlled trials should start to be overcome. The proposal in this chapter is that philosophy is essential in this process. By reviewing select examples from the history of science and philosophy, disciplines which were indistinguishable until the mid-nineteenth century, I argue that progress toward the many impasses in biomedicine can be achieved by emphasizing theoretical work (in the true sense of the word “theory”) as a vital foundation for experimental biology. Furthermore, a philosophical biology program that could provide a framework for theoretical investigations is outlined.

“…W ater is essential to nearly all biological, climatological, and industrial functions on planet Earth. Of enduring scientific interest are the various phase transitions undergone by water, both within the liquid state and between its numerous condensed phases [1][2][3][4][5][6] . One phase transformation of emerging importance is the freezing of water in an undeformable, constant-volume container.…”

Freezing water at constant volume and under confinement

Water expands upon freezing. What happens when water is cooled below 0°C in an undeformable, constant-volume container? This is a fundamental question in materials thermodynamics, and is also relevant in biological, geological, and technological applications in which ice forms under nano-, meso-, or macroscale confinement. Here, we analyze the phase-equilibria and kinetic behaviors of water and ice-1h in an isochoric (constant-volume) system. By making use of the Helmholtz potential F(temperature, volume), in contrast to the Gibbs potential G(temperature, pressure), we demonstrate significant changes in phase behavior when the specific volume of the container is constrained below that of ice-1h. We construct a T-V (temperature-volume) phase diagram for water and ice that features a broad two-phase equilibrium region, and we further derive an isochoric nucleation theory that reveals the existence of a critical confinement volume, on the order of microns, below which ice-1h is kinetically prohibited from forming.
