The premelting of ice is well known, but little is known about how the premelted and solid surfaces convert to each other. In this work, the transition dynamics between two phases are revealed with large‐scale molecular dynamics simulations. Supercooling and superheating states exist in the transition, and are overcome…

'Kazimierz Orzechowski' 'Aneta Jezierska' 'Adrian Daniel Boese'] The experimental and theoretical description of premelting behavior is one of the most challenging tasks in contemporary material science. In this paper, n-octanol was studied using a multi-method approach to investigate it at macroscopic and molecular…

A disordered quasi-liquid layer of water is thought to cover the ice surface, but many issues such as its onset temperature, its thickness, or its actual relation to bulk liquid water have been a matter of unsettled controversy for more than a century. In this perspective article, current computer simulations and…

Since two major criteria for melting were proposed by Lindemann and Born in the early 1900s, many simulations and observations have been carried out to elucidate the premelting phenomena largely at the crystal surfaces and grain boundaries below the bulk melting point. Although dislocations and clusters of vacancies…

The premelting layer at the ice-air interface plays critical roles in atmospheric chemical and physical processes. Traditional approaches to study this layer—experimental methods, classical simulations, and even first-principles simulations—face significant limitations in accuracy and scalability. Addressing these…

The nature of liquid-to-glass transition is a major puzzle in science. A similar challenge exists in glass-to-liquid transition, i.e., glass melting, especially for the poorly investigated surface effects. Here, we assemble colloidal glasses by vapor deposition and melt them by tuning particle attractions. The…

Nucleation Authors: ['Łukasz Baran' 'Pablo Burriel Llombart' 'Luis G. MacDowell'] The interface of ice with solids plays an exceptionally important role on a wide variety of natural phenomena, such as the melting of permafrost, sliding of glaciers or frost heaving; as well as on many important technological…

Under certain conditions, pulsed laser deposition-grown BiFeO3 thin films can exhibit a high density of non-stoichiometric line defects and planar defects. The defective regions, characterized by altered lattice periodicity, local atomic configurations, and electronic states, are expected to respond to external stimuli…

'Jonghun Yoon' 'José A.F.O. Correia' 'Filippo Berto' 'Abílio M.P. De Jesus'] In the production of titanium alloy, the electron beam cold hearth melting (EBCHM) process is commonly used due to its effectiveness and the high quality of the end product. However, its main drawback is the significant loss of elements such…

'Donald A. Klosterman' 'Li Cao' 'Francesco Baino' 'Maziar Montazerian'] Ceramic materials are used in various industrial applications, as they possess exceptional physical, chemical, thermal, mechanical, electrical, magnetic, and optical properties. Ceramic structural components, especially those with highly complex…
