Bulk water exists in many forms, including liquid, vapour and numerous crystalline and amorphous phases of ice, with hexagonal ice being responsible for the fascinating variety of snowflakes. Much less noticeable but equally ubiquitous is water adsorbed at interfaces and confined in microscopic pores. Such low-dimensional water determines aspects of various phenomena in materials science, geology, biology, tribology and nanotechnology. Theory suggests many possible phases for adsorbed and… 
Hydrophobic Ice Confined between Graphene and MoS2
The structure and nature of water confined between hydrophobic molybdenum disulfide (MoS2) and graphene (Gr) are investigated at room temperature by means of atomic force microscopy. We find the
Water Confined in Nanocapillaries: Two-Dimensional Bilayer Squarelike Ice and Associated Solid-Liquid-Solid Transition
Despite recent experimental evidence of the two-dimensional (2D) square ice in graphene nanocapillaries, based on transmission electron microscopy (TEM) imaging, the AA-stacked bilayer square ice
Structural and dynamic characteristics in monolayer square ice.
When water is constrained between two sheets of graphene, it becomes an intriguing monolayer solid with a square pattern due to the ultrahigh van der Waals pressure. However, the square ice phase has
Low-Dimensional Confined Ice Has the Electronic Signature of Liquid Water.
TLDR
A first-principle energy decomposition analysis is applied to reveal that the strength and patterns of donor-acceptor interactions between molecules in these low-dimensional ice structures resemble those in bulk liquid water rather than those in hexagonal ice.
Formation of Trilayer Ices in Graphene Nanocapillaries under High Lateral Pressure
Using molecular dynamics simulation, we investigate the phase behavior of water confined in graphene nanocapillaries at room temperature (300 K). Here, the lateral pressure Pzz is used as the primary
Synthesis of Honeycomb-Structured Beryllium Oxide via Graphene Liquid Cells.
TLDR
This work shows that beryllium oxide crystallizes in the hexagonal structure in the graphene liquid cell by the wet chemistry approach, and shows that the energy barrier of the phase transition is responsible for the observed hexagonal layers beyond the previously predicted limit.
Water in Inhomogeneous Nanoconfinement: Coexistence of Multilayered Liquid and Transition to Ice Nanoribbons.
TLDR
Findings of phase behaviors of water under the inhomogeneous nanoconfinement not only extend the phase diagram of confined water but also have implications for realistic nanofluidic systems and microporous materials.
The purported square ice in bilayer graphene is a nanoscale, monolayer object.
TLDR
Simulated core-level spectroscopy reveals unambiguous orientation dependent signatures of square ice that should be discernable in experiments, and free energy calculations show that this motif is thermodynamically stable up to diameters of approximately 15 nm.
Phase Diagram of Water Confined by Graphene
TLDR
This study determines the phase diagram of water confined by graphene sheets in slab geometry, and finds that, depending on the confining dimension D and density σ, water can exist in liquid and vapor phases, or crystallize into monolayer and bilayer square ices, as observed in experiments.
AB-stacked square-like bilayer ice in graphene nanocapillaries.
TLDR
A new crystalline structure of bilayer ice with the AB-stacking order is observed from molecular dynamics simulations of constrained water, reflecting the compression/tensile limit of the 2D monolayer/bilayer ice.

No confinement needed: observation of a metastable hydrophobic wetting two-layer ice on graphene.
TLDR
The results show that the two-layer ice forms even at zero pressure at a single hydrophobic interface by maximizing the number of hydrogen bonds at the expense of adopting a nontetrahedral geometry with weakened hydrogen bonds.

TLDR
Insights obtained from pressure-induced amorphization and crystallization of confined water offer a guide with which to seek a thermodynamic path to grow a new form of methane clathrate whose BL ice framework exhibits the Archimedean 4⋅82 (square-octagon) pattern.
Phase diagram of water in carbon nanotubes
TLDR
A phase diagram of water in single-walled carbon nanotubes at atmospheric pressure is proposed, which summarizes ice structures and their melting points as a function of the tube diameter up to 1.7 nm, suggesting that there exist at least nine ice phases in the cylindrical space.
Ordered water structure at hydrophobic graphite interfaces observed by 4D, ultrafast electron crystallography
TLDR
4D, ultrafast electron crystallography with atomic-scale spatial and temporal resolution is used for study of structure and dynamics of interfacial water assembly on a hydrophobic surface, finding vertically stacked bilayers on highly oriented pyrolytic graphite surface were determined to be ordered, contrary to the expectation that the strong hydrogen bonding of water on Hydrophobic surfaces would dominate with suppressed interfacial order.
Phase Transitions of Water in Graphite and Mica Pores
We report all-atom molecular dynamics simulations of water confined in graphite and mica slit pores of variable size ranging from 10 to 60 A. For each pore size, we demonstrate that the confinement

TLDR
A new type of liquid cell for in situ transmission electron microscopy (TEM) based on entrapment of a liquid film between layers of graphene that facilitates atomic-level resolution imaging while sustaining the most realistic liquid conditions achievable under electron-beam radiation is introduced.
Graphene Visualizes the First Water Adlayers on Mica at Ambient Conditions
TLDR
Graphene is used as an atomically flat coating for atomic force microscopy to determine the structure of the water adlayers on mica at room temperature as a function of relative humidity, and results indicate nanometer-scale surface defects serve as nucleation centers for the formation of both the first and the second adlayer.
Control of radiation damage in MoS(2) by graphene encapsulation.
TLDR
It is demonstrated, on the example of MoS2, that encapsulation of such crystals between two layers of graphene allows for a dramatic improvement in stability of the studied 2D crystal and permits careful control over the defect nature and formation in it.
Phase transitions induced by nanoconfinement in liquid water.
TLDR
Results from molecular dynamics simulations of water confined by two parallel atomically detailed hydrophobic walls show that a first order transition occurs between a bilayer liquid and a trilayer heterogeneous fluid as water density increases.
Molecular dynamics simulation of the ice nucleation and growth process leading to water freezing
TLDR
A molecular dynamics trajectory is presented that captures the molecular processes involved in the freezing of pure water and finds that ice nucleation occurs once a sufficient number of relatively long-lived hydrogen bonds develop spontaneously at the same location to form a fairly compact initial nucleus.
