In addition to the gas and liquid phases, water can exist in many different solid states. Some of these are the well–studied crystalline ice polymorphs and the clathrate hydrates, but at least two distinguishable amorphous solid forms have also been shown to exist. This diversity of possible condensed states implies a multiplicity of transitions, each of them presumably associated with a nucleation step. Disagreement still exists as to whether the amorphous states can be regarded as metastable… Expand
Ice nucleation on BaF2(111).
TLDR
Calculations consistent with the experimental results demonstrate that the pitting of a submerged BaF(2) crystal dramatically improves its ice nucleating ability. Expand
Brief Overview of Ice Nucleation
TLDR
The author’s wish is to aid early researchers in ice nucleation and those who wish to get into the field of iceucleation from other disciplines by concisely summarizing the outstanding issues in this important field. Expand
Effect of the Degree of Oil Biodegradation on the Crystallization of Methane Hydrate and Ice in Water-Oil Emulsions
To study the influence exerted by oxidized oil components on the nucleation and growth of gas hydrates the nucleation of methane hydrate and ice in 50 wt % emulsions of oil in native oil and twoExpand
Hydrodynamics and Thermodynamics of Ice Accretion through Impact of Supercooled Large Droplets: Experiments, Simulations and Theory
Icing of solid surfaces is an ever-present problem for many engineering applications. In particular ice accretion due to the impact and freezing of supercooled water drops is rich in various physicalExpand
A Low Temperature Limit for Life on Earth
TLDR
Since cells must return to a fluid state to resume metabolism and complete their life cycle, and ice is almost universally present in environments at sub-zero temperatures, it is proposed that the vitrification temperature represents a general lower thermal limit to life on Earth, though its precise value differs between unicellular and multicellular organisms.

Ice-Templating and Freeze-Casting: Control of the Processes, Microstructures, and Architectures
The nucleation and growth of crystals in a colloidal suspension can be described in a few words: crystals are formed, grow, and the particles move (or not). The previous chapters have neverthelessExpand
The nucleation of ice in supercooled D2O and H2O
Abstract The homogeneous nucleation rates of light and heavy water have been measured in supercooled levitated micro-droplets at different temperatures using a temperature jump experiment.Expand
Nucleation of Gas Hydrates
This chapter introduces nucleation of gas hydrates. Clathrate hydrate is, by definition, a multi-component system that has at least two components of a guest gas and water. Nucleation of clathrateExpand
Microbial communities in submarine permafrost and their response to permafrost degradation and warming
The Arctic region is especially impacted by global warming as temperatures in high latitude regions have increased and are predicted to further rise at levels above the global average. This isExpand
Ice nucleation by electric surface fields of varying range and geometry.
TLDR
It is found that ice nucleated by field bands usually grows as a mixture of cubic and hexagonal ice, consistent with other simulations of ice growth, and with experiment, and it is argued that this discrepancy is a simulation artifact related to finite sample size and periodic boundary conditions.

Ice nucleation and freezing in undercooled cells.
TLDR
DSC has been employed to study the effect of cooling on a range of cells under exclusion of extracellular ice and in the absence of chemical cryoprotectants, and shows the rates to be consistent with the dimensions of the plant cells (or organelles), if these were to be the active nucleators.

Nucleation Kinetics of Ice in Undercooled Yeast Cells: Long-term Stability against Freezing
SUMMARY: Undercooling and ice nucleation in yeast cells exposed to increasing hypertonic polyvinyl-pyrrolidone (PVP) concentrations were measured. Ice nucleation rates were analysed in terms ofExpand

Nucleation and growth of ice in deeply undercooled erythrocytes.
TLDR
No cross-nucleation occurs between individual cells packed within the same emulsified water droplet and the differential scanning calorimetric power-time curves of intact cells and ghosts are identical, indicating that hemoglobin does not affect ice nucleation. Expand

Abstract An emulsion droplet formation procedure was employed to isolate yeast cells and, in separate experiments, human red blood cells, one from another in individual droplets, and to segregateExpand
