Diamond is a promising material for wear-resistant medical coatings. Here we report a remarkable increase in the melting point of ice resting on a diamond (111) surface modified with a submonolayer of Na+. Our molecular dynamics simulations show that the interfacial ice bilayer melts at a temperature 130 K higher than in free ice, and relatively thick ice films (2.6 nm at 298 K and 2.2 nm at 310 K ) are stabilized by dipole interactions with the substrate. This unique physical effect may enable…

Orientation of water molecules by the diamond surface

The properties of water in suspensions of diamond powders with particle sizes from 125–160 μm to 2–10 nm were studied. The dielectric constant of water in these suspensions changed from 1.3 × 103 to

Sensing phases of water via nitrogen-vacancy centres in diamond

TLDR
A theoretical work is presented, complemented with numerical evidence based on bosonization techniques, that predicts the measurable signal from a single NV centre when interacting with large spin baths in different configurations.

Sensing phase-transitions via nitrogen-vacancy centers in diamond

Ultra-thin layers of liquids on a surface behave differently from bulk liquids due to liquid-surface interactions. Some examples are significant changes in diffusion properties and the temperature at

Simulations of water at the interface with hydrophilic self-assembled monolayers (Review)

TLDR
Simulations of water at the interface with hydrophilic self-assembled monolayer (SAM) surfaces find that while the interfacial water molecules are slower than the bulk water molecules, the interf facial dynamics remains that of a liquid.

Transient hydroxyl formation from water on oxygen-covered Au(111).

TLDR
The results identify transient hydroxyls as species that could play a critical role in oxidative chemical reactions on gold, especially in ambient water vapor, and demonstrate that oxidation of interfaces has a major impact on their interaction with water.

Triple points and coexistence properties of the dense phases of water calculated using computer simulation.

TLDR
The numerical results for the triple points and for the change in volume, Deltav, and enthalpy, DeltaH, along the coexistence lines involving liquid water and/or ices ih, II, III, V and VI for several simple water models are reported.

Determination of phase diagrams via computer simulation: methodology and applications to water, electrolytes and proteins

In this review we focus on the determination of phase diagrams by computer simulation, with particular attention to the fluid–solid and solid–solid equilibria. The methodology to compute the free

Icelike Water Monolayer Adsorbed on Mica at Room Temperature

The structure of a water film formed on mica at room temperature, in equilibrium with water vapor at various relative humidities (RH), was studied using sum-frequency-generation (SFG) vibrational

Freezing of Confined Water: A Bilayer Ice Phase in Hydrophobic Nanopores

Molecular dynamics simulations were performed to study the phase behavior of a thin film of water confined to a slit nanopore with smooth walls. A first-order water-to-ice freezing transition has

Surface-induced ferroelectric ice on Pt(111)

Optical sum-frequency vibrational spectroscopy and thermal desorption are used to study ice films grown on Pt(111). The strong enhancement of OH stretch resonances with film thickness provides clear

Freezing transition of interfacial water at room temperature under electric fields.

TLDR
This new type of freezing mechanism, occurring in weak electric fields and at room temperature, may have immediate implications for ice formation in diverse natural environments.

Structure of water adsorbed on a mica surface.

TLDR
The calculated water O density profile was in quantitative agreement with recent x-ray reflectivity measurements indicating strong lateral ordering of the hydration water but liquidlike disorder otherwise.

TLDR
Proliferation and morphology of L929 mouse fibroblasts reveal improved biocompatibility of Ca-O-modified DLC and CaCO3 was identified by X-ray induced photoelectron spectroscopy.

TLDR
The results of the tests show that in all the combinations studied, amorphous diamond coating improved definitely the wear and corrosion resistance compared with the uncoated materials.
