Rosetta observes sublimating surface ices
Science, 2016Cometary Science Comets are “dirty snowballs” made of ice and dust, but they are dark because the ice sublimates away, leaving some of the dust behind on the surface. The Rosetta spacecraft has provided a close-up view of the comet 67P/Churyumov-Gerasimenko as it passes through its closest point to the Sun (see the Perspective by Dello Russo ...

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

Thin Ice Films at Mineral Surfaces
The Journal of Physical Chemistry Letters, 2016Ice films formed at mineral surfaces are of widespread occurrence in nature and are involved in numerous atmospheric and terrestrial processes. In this study, we studied thin ice films at surfaces of 19 synthetic and natural mineral samples of varied structure and composition.

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 ...

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

Viscosity of the ice surface layer
The Journal of Chemical Physics, 1980The thermal contraction of ice single crystals between 0 and −50 °C has been measured by the use of silicon strain gauges frozen on the crystal basal surface. The experimental results cannot be explained without assuming the existence of a Newtonian viscous layer at the ice-strain-gauge interface; this layer has a thickness which changes in temperature

There is a widespread opinion that ice surfaces are covered by a liquid layer at equilibrium, and several treatments of the ice surface describe it as a homogeneous layer with a definable thickness. Arguments are presented that the ice surface cannot have a homogeneous surface layer and that representations of it that use such a layer are not useful ...

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 ...

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.
