TLDR
Radial distribution functions indicate that the structure evolves systematically between 4 and 8 angstroms, and the phase transformations in low-temperature liquid water may be much more complex than currently understood.Abstract:
Structural changes during annealing of high-density amorphous ice were studied with both neutron and x-ray diffraction. The first diffraction peak was followed from the high- to the low-density amorphous form. Changes were observed to occur through a series of intermediate forms that appear to be metastable at each anneal temperature. Five distinct amorphous forms were studied with neutron scattering, and many more forms may be possible. Radial distribution functions indicate that the structure evolves systematically between 4 and 8 angstroms. The phase transformations in low-temperature liquid water may be much more complex than currently understood.read more

Supercooled and glassy water
TL;DR: The authors summarizes the known experimental facts and reviews critically theoretical and computational work aimed at interpreting the observations and providing a unified viewpoint on cold, non-crystalline, metastable states of water.

Supercooled and glassy water
TL;DR: In this article, a coherent interpretation of water's properties is beginning to emerge from recent experimental and theoretical investigations, and a cold, non-crystalline states play an important role in understanding the physics of liquid water.

TL;DR: It is demonstrated that femtosecond X-ray laser pulses can be used to probe the structure of liquid water in micrometre-sized droplets that have been evaporatively cooled below TH, and experimental evidence is found for the existence of metastable bulk liquid water down to temperatures of kelvin in the previously largely unexplored no man’s land.

The structural origin of anomalous properties of liquid water
TL;DR: Water is the most common liquid in nature, with unusual properties that could be linked to the peculiar hydrogen-bonding network holding the molecules together, according to Nilsson and Pettersson and colleagues.

TL;DR: From the frontiers of research on ice dynamics in its broadest sense, the authors surveys the structures of ice, the patterns or morphologies it may assume, and the physical and chemical processes in which it is involved.

The relationship between liquid, supercooled and glassy water
Osamu Mishima,H. Eugene Stanley +1 more
TL;DR: This article showed that water can exist in two distinct "glassy" forms, low and high density amorphous ice, which may provide the key to understanding some of the puzzling characteristics of cold and supercooled water.

‘Melting ice’ I at 77 K and 10 kbar: a new method of making amorphous solids
TL;DR: Amorphous solids are made mainly by cooling the liquid below the glass transition without crystallizing it, a method used since before recorded history1, and by depositing the vapour onto a cold plate2, as well as by several other methods as discussed by the authors.

Structures of high-density and low-density water
TL;DR: The three site-site partial structure factors for water have been measured as a function of pressure, using neutron diffraction, at a temperature of 268 K and it is found that the measured structure functions imply a continuous transformation with increasing pressure.

Reversible first‐order transition between two H2O amorphs at ∼0.2 GPa and ∼135 K
TL;DR: In this paper, the transition between low and high density amorphous H2O was observed with a pistoncylinder apparatus from 77 K to 140 K, almost the glass-transition temperature of the amorphs.

TL;DR: Neutron diffraction with isotope substitution is used to determine the structures of high (HDA) and low (LDA) density amorphous ice, with implications for the nature of the HDA-LDA transition that bear on the current metastable water debate.
