This work is the first to show that the ion specificity in tuning HIN on ionic surfaces follows the Hofmeister series. Heterogeneous ice nucleation (HIN) on ionic surfaces is ubiquitous in a wide range of atmospheric aerosols and at biological interfaces. Despite its great importance in cirrus cloud formation and cryopreservation of cells, organs, and tissues, it remains unclear whether the ion-specific effect on ice nucleation exists. Benefiting from the fact that ions at the polyelectrolyte… 
Inhibition of Heterogeneous Ice Nucleation by Bioinspired Coatings of Polyampholytes.
Inspired by antifreeze proteins, the PBS-based polyampholytes, containing both negative and positive charge groups on a single chain, show excellent performance of ice nucleation inhibition and freezing delay and have shown application value of tuning iceucleation via a simple spin-coating method.
Use of Ion Exchange to Regulate the Heterogeneous Ice Nucleation Efficiency of Mica.
The experiments show that the surface (001) of H+-exchanged mica displays markedly higher HIN efficiencies than that of Na-/K-mica, and vibrational sum-frequency generation spectroscopy reveals that H- mica induces substantially less orientation ordering than Na- /K-Mica within the contact water layer at the interface.
Multivalent Surface Cations Enhance Heterogeneous Freezing of Water on Muscovite Mica.
The results indicate that multivalent cations enhance the probability of forming large clusters of hydrogen bonded water molecules that are anchored by the hydration shells of the cations that could serve as seedbeds for ice nuclei.

Through synergistically controlling of ice nucleation and propagation delay times, this work can tune the freezing delay time of water droplets on multilayer hydrogel surfaces up to 3 orders of magnitude via changing various counterions.
Counterion Specificity of Polyelectrolyte Brushes: Role of Specific Ion-Pairing Interactions.
It is demonstrated here that the properties of poly (2-(methacryloyloxy) ethyl trimethylammonium chloride) brushes can be tuned by counterion species through modulating the osmotic pressure within the brushes and the hydrophobicity of the ion pairs.
Critical In-Plane Density of Polyelectrolyte Brush for the Ordered Hydrogen-Bonded Structure of Incorporated Water.
A polymer electrolyte brush is a reasonable platform to confine water molecules within a nanoscopic area to study their role in the function of interacting media because of their adjustable nanospace
Heterogeneous Electrofreezing of Super Cooled Water on Surfaces of Pyroelectric Crystals is Trigered by Planar-Trigonal Ions.
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.

Ice formation on surfaces is a serious issue in many different fields in terms of function, safety, and cost of operation in human life. Hydrophobic coating technology is one of the effective ways to

By simply changing the initial type and concentration of ions in an aqueous solution, the size of ice grains after recrystallization can be tuned from 27.4±4.1 to 277.5±30.9 μm.

Counterion effect on interfacial water at charged interfaces and its relevance to the Hofmeister series.
Heterodyne-detected vibrational sum-frequency generation spectroscopy was applied to study the counterion effect on the interfacial water at charged interfaces to provide new insights into the molecular level mechanisms of anionic and cationic Hofmeister effects.
Source of Electrofreezing of Supercooled Water by Polar Crystals.
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.
Spherical Polyelectrolyte Brushes
Investigating the effects of solid surfaces on ice nucleation.
The water microdroplets formed on flat, solid surfaces by an evaporation and condensation process exclude the uncontrollable impurities in water, and the effects of surface heterogeneities can be minimized through studying the freezing of ensembles of separate and independent water micro droplets.
Heterogeneous nucleation of ice on carbon surfaces.
It is found that atomically flat carbon surfaces promote heterogeneous nucleation of ice, while molecularly rough surfaces with the same hydrophobicity do not, and that a characterization of the nanostructure of soot is needed to predict its ice nucleation efficiency.

Results from the protein monolayer suggested that specific anion effects are dominated by the charge state of the interfacial layer rather than its detailed chemical structure.
