Ice-Phobic Surfaces That Are Wet
ACS Nano, 2012Ice formation on surfaces and structures produces damage and inefficiencies that negatively impact all manners of activities. Not surprisingly, for a long time, an unmet challenge has been to design materials capable of minimizing or even eliminating the formation of ice on the surface of the material. In recent years, there were significant efforts to

The main objective of the present study is to further our understanding of the influence of ambient temperature, freezing water conductivity and nature of applied voltage on the surface flashover of ice. Flashover tests were carried out using two metallic hemispherical capped rods 12 mm in diameter, separated by an ice surface. The distance between the

Adhesion of impure ice on surfaces
Materials HorizonsImpurities in water affect ice adhesion strength on surfaces. Depending on the freezing rate, they can be trapped in ice or pushed out, forming a lubricating layer. They also affect the quasi-liquid layer between ice and surface, impacting adhesion.

In this review, we summarize the available experimental data from recently developed molecular level techniques on the surface structure, surface premelting layer thickness, and friction of ice. We conclude that surface premelting of ice is responsible for the unique surface properties of the important substance.

Carbon Monoxide Hydrogenation on Ice Surfaces
ChemPhysChem, 2018AbstractWe have performed density functional calculations to investigate the carbon monoxide hydrogenation reaction (H+CO→HCO), which is important in interstellar clouds. We found that the activation energy of the reaction on amorphous ice is lower than that on crystalline ice. In the course of this study, we demonstrated that it is roughly possible to

ce adhesion of pure water has been studied throughout literature and the reduction of ice adhesion assumes primary importance to society. There have been many studies conducted on how the ice adhesion strength can be reduced for various substrates which led to the development of superhydrophobic surfaces, textured surfaces, hydrophobic and icephobic ...

Interface Science, 2001
The dynamics of faceted and partially faceted single crystal and polycrystalline ice are reviewed with an emphasis on the manner in which microscopic effects produce macroscopic shapes. Our understanding of the former is rooted in the basic kinetics common to all materials and our pursuit of the latter is largely motivated by the striking patterns ...

Processes on the surface of ICE
Surface Science, 1967Abstract Several reported experiments (viz. cohesion of ice spheres, sintering between ice spheres, evaporation from the edge of snow crystals, advancing layers across a growing ice surface, surface electrical conduction in deposited snow) are critically compared and correlated.
