“…In the vapor case, as N i increases, the film thickens, as expected, and the temperature at which this power law ͑d ϰ⌬T −1 ͒ begins to dominate the melting behavior decreases. The effect is particularly sensitive in the vapor case where it may overwhelm the incomplete melting controlled by van der Waals interactions in the pure case ͑Elbaum and Schick, 1991; and drive complete surface melting, thereby reconciling the difference between experimental observations made in different laboratories ͑Beaglehole and Nason, 1980; Dosch et al, 1996;Furukawa and Nada, 1997͒. As the temperature decreases, the first crossover to interfacial melting controlled by van der Waals interactions appears ͑d ϰ⌬T −1/3 ͒.…”

“…where q s is the surface charge density associated with the Bjerrum defect density ͑e.g., Dosch et al, 1996͒. In the classical context of DLVO theory, the Debye length is a constant, and Eq. ͑25͒ can be considered in the same sense as F vdW NR ͑d͒ above.…”

“…The missing bonds at any ice surface give rise to an increase in the Bjerrum defect density and hence the surface can be considered to have a finite charge density q s ͑e.g., Dosch et al, 1996;Dash et al, 2001͒. Therefore any ions present in the film will screen the Coulomb interaction with an efficiency that depends on their number density.…”

The physics of premelted ice and its geophysical consequences

The surface of ice exhibits the swath of phase-transition phenomena common to all materials and as such it acts as an ideal test bed of both theory and experiment. It is readily available, transparent, optically birefringent, and probing it in the laboratory does not require cryogenics or ultrahigh vacuum apparatus. Systematic study reveals the range of critical phenomena, equilibrium and nonequilibrium phase-transitions, and, most relevant to this review, premelting, that are traditionally studied in more simply bound solids. While this makes investigation of ice as a material appealing from the perspective of the physicist, its ubiquity and importance in the natural environment also make ice compelling to a broad range of disciplines in the Earth and planetary sciences. In this review we describe the physics of the premelting of ice and its relationship with the behavior of other materials more familiar to the condensed-matter community. A number of the many tendrils of the basic phenomena as they play out on land, in the oceans, and throughout the atmosphere and biosphere are developed.

Abstract. A new model describes charge and mass transfer in ice-ice collisions in terms of fundamental molecular physics. Drawing on clues from results of recent and earlier experiments, the theory treats the collisions as interlinked events acting in three stages: before collision, during contact, and withdrawal. The theory provides quantitative descriptions of charge and mass transfer and their dependence on growth rate, temperature, and impact energy. Application of the theory to experimental simulations of thunderstorm charging explains general trends in terms of basic microscopic processes.

In chemistry, biology, and materials science, ice‐mediated reactions and ice‐template assembly techniques are garnering increasing attention due to their unique advantages. Such approaches not only offer deep insights into the fundamental roles of ice in nature but also pave new avenues for various applications. This review comprehensively explores the mechanisms and applications of ice‐mediated reactions and assembly. It begins by examining the principles of ice‐mediated reactions, particularly how certain chemical reactions are accelerated in the micro‐environment of ice through freeze‐concentration and freeze‐potential effects, and the relationship between the surface structure and properties of ice and chemical reactions. This work then studies significant chemical reactions within the realms of environmental, biological, and materials science engineering, shedding light on the role of ice in these reactions. Furthermore, this work explores the fundamentals of ice templating in material assembly, describe the main ice‐templating methods, and highlight the ice‐templated materials along with their diverse applications. This work concludes by summarizing the prospective challenges and untapped potentials in the field of ice‐mediated reactions and assembly. This review not only accentuates the transformative impact of ice‐mediated techniques in scientific domains but also serves as an useful guide for future research initiatives and practical applications in this burgeoning field.
