Freezing Supercool Water Under equilibrium conditions, water will freeze at 0°C, but, under certain conditions, it can be kept in a supercooled liquid form below this temperature. Ehre et al. (p. 672) present a careful and detailed study of the freezing of water drops on both positively and negatively charged pyroelectric surfaces using a combination of optical microscopy and x-ray diffraction: Supercooled water froze at different temperatures, depending on the charge of the substrate with the… Expand
Source of Electrofreezing of Supercooled Water by Polar Crystals.
TLDR
It is demonstrated that preventing the formation of charge at these surfaces, by linking the two hemihedral faces of the polar crystals with a conducting paint, reduces the temperature of freezing by 2-5 °C, implying that the surface-charge-induced interactions affect the interfacial water molecules that trigger freezing at a higher temperature.

Heterogeneous Electrofreezing as Triggered by CO2 on Pyroelectric Crystals. A Qualitative Difference of Icing on Hydrophilic and Hydrophobic Surfaces.
By performing icing experiments on hydrophilic and hydrophobic surfaces of pyroelectric amino acids and on the x-cut faces of LiTaO 3 , we discovered that the effect of electrofreezing of superExpand
An electrochemical in situ study of freezing and thawing of ionic liquids in carbon nanopores.
TLDR
This study shows that RTILs may show a tremendously different thermal behavior when comparing bulk with nanoconfined properties as a result of the increased surface energy of carbon pore walls, accompanied by slowed-down charge-discharge kinetics as seen with in situ electrochemical characterization.

Surface-charge-induced orientation of interfacial water suppresses heterogeneous ice nucleation on α -alumina (0001)
Abstract. Surface charge is one of the surface properties of atmospheric aerosols, which has been linked to heterogeneous ice nucleation and hence cloud formation, microphysics, and opticalExpand
Water freezes at near-zero temperatures using carbon nanotube based electrodes under static electric fields.
TLDR
A systematic study of the effect of an electric field on water freezing by varying the thickness of a dielectric layer and the voltage across it in an electro-wetting system reveals that this behavior is due to saturation in the contact angle of the ice embryo with the underlying substrate. Expand
Heterogeneous Electrofreezing of Super Cooled Water on Surfaces of Pyroelectric Crystals is Trigered by Planar-Trigonal Ions.
TLDR
Molecular dynamic simulations suggest that the hydrated planar-trigonal HCO 3 ⁻ ions self-assemble with water molecules near the surface of the AgI crystal as clusters of slightly different configuration from those of the ice-like hexagons, but these clusters have a tendency to serve as embryonic nuclei for ice crystallization.

Freezing of water next to solid surfaces probed by infrared-visible sum frequency generation spectroscopy.
TLDR
It is believed that the segregation of sodium ions next to the negatively charged sapphire substrate may be responsible for disrupting the charge transfer and stitching bilayer at high pH, providing a plausible explanation for the experimental observations. Expand
Morphology of supercooled droplets freezing on solid surfaces
Supercooled droplets freezing on solid surfaces are ubiquitous in nature. This letter investigates the influences of droplet viscosity on freezing velocity and frosting formation. Several experimentsExpand
Electrofreezing of water droplets under electrowetting fields.
TLDR
This work studies ice nucleation in electrowetted water droplets, wherein there is no electric field inside the droplet resting on a dielectric layer, and there is an interfacial electric field and charge buildup at the solid-liquid interface. Expand
Mechanism of supercooled droplet freezing on surfaces.
TLDR
A novel perspective to icing and icephobicity is brought, unveiling the strong influence of environmental conditions in addition to the accepted effects of the surface conditions and hydrophobicity. Expand

Heterogeneous surface crystallization observed in undercooled water.
TLDR
Observations of higher freezing temperatures when an ice-forming nucleus is near the surface of an undercooled water drop than when the nucleus is immersed in the drop are reported, thereby complementing and providing evidence for homogeneous surface crystallization, which has been hypothesized recently.

TLDR
A critical radius r(c) of appromximately 15 nm for a water droplet and a critical thickness delta( c) of approximately 10 nm for water's flat film is calculated, which provides a thermodynamic basis for the occasionally found presence of cubic ice in the atmosphere and explains why water's nanometers-sized clusters and water confined to nanometer-sized pores freeze to cubic ice.
