Neutrons meet ice polymorphs

K Komatsu - Crystallography Reviews, 2022 - Taylor & Francis
The current epoch can be described as the 'age of ice-rush', as the rate of discovery of ice
polymorphs, of which there are currently 20 known, has accelerated, particularly since the …

[HTML][HTML] Nucleation and growth of crystalline ices from amorphous ices

CM Tonauer, LR Fidler, J Giebelmann… - The Journal of …, 2023 - pubs.aip.org
We here review mostly experimental and some computational work devoted to nucleation in
amorphous ices. In fact, there are only a handful of studies in which nucleation and growth in …

GenIce-core: Efficient algorithm for generation of hydrogen-disordered ice structures

M Matsumoto, T Yagasaki, H Tanaka - The Journal of Chemical …, 2024 - pubs.aip.org
Ice is different from ordinary crystals because it contains randomness, which means that
statistical treatment based on ensemble averaging is essential. Ice structures are …

Anomalous hydrogen dynamics of the ice VII–VIII transition revealed by high-pressure neutron diffraction

K Komatsu, S Klotz, S Machida… - Proceedings of the …, 2020 - pnas.org
Above 2 GPa the phase diagram of water simplifies considerably and exhibits only two solid
phases up to 60 GPa, ice VII and ice VIII. The two phases are related to each other by …

Disordering effect of the ammonium cation accounts for anomalous enhancement of heterogeneous ice nucleation

TF Whale - The Journal of Chemical Physics, 2022 - pubs.aip.org
Heterogeneous nucleation of ice from supercooled water is the process responsible for
triggering nearly all ice formation in the natural environment. Understanding of …

[HTML][HTML] The impact of alcohol and ammonium fluoride on pressure-induced amorphization of cubic structure I clathrate hydrates

LR Fidler, P Posch, J Klocker, Z Sharif, JJ Shephard, B Slater, CL Bull… - The Journal of …, 2021 - pubs.aip.org
Ice III is a hydrogen-disordered phase of ice that is stable between about 0.2 and 0.35 GPa.
Upon cooling, it transforms to its hydrogen-ordered counterpart ice IX within the stability …

Ice zone melting method for probing ion-specific partitioning at frozen interface

Y Yashima, M Harada, T Okada - Colloids and Surfaces A: Physicochemical …, 2024 - Elsevier
When water freezes, impurities are expelled from the ice crystals and accumulate in the
grain boundary space. Salts are a major impurity common to aqueous systems and, upon …
