Surface melting or non-melting
Surface Science Letters, 1987We study the general conditions for the occurrence of surface melting by describing the solid-vapour interface Gibbs free energy as a Cahn-Hilliard functional of density ρ and crystal order y . The Euler equations of this variational problem yield one or more physical trajectories in the (ρ, y ) plane running from vapour to solid at a variable ...

AbstractMelt electrospinning is relatively under‐investigated compared to solution electrospinning but provides opportunities in numerous areas, in which solvent accumulation or toxicity are a concern. These applications are diverse, and provide a broad set of challenges to researchers involved in electrospinning.

Science, 1984
Radiation from a Q-switched YAG laser, focused on the (100) face of a single crystal diamond anvil in a high-pressure diamond cell, caused a portion of the diamond anvil face to melt. Potassium bromide mixed with graphite was under pressure between the anvils when melting occurred.

Proceedings of the 2002 ACM SIGGRAPH/Eurographics symposium on Computer animation - SCA '02, 2002
We present a fast and stable system for animating materials that melt, flow, and solidify. Examples of real-world materials that exhibit these phenomena include melting candles, lava flow, the hardening of cement, icicle formation, and limestone deposition.

A disorder model of melting and melts
physica status solidi (b), 1967AbstractVarious thermal properties of molten metals are calculated assuming a strong correspondence between the crystal and the melt. Thus, the properties of melts are composed of a “lattice dependent” term, essentially equal to the value of the property for the crystal at its melting point, and a “defect dependent” term, calculable from the theory of ...

Methods, 2007
Melting curves are commonly used to determine the stability of folded nucleic acid structures and their interaction with ligands. This paper describes how the technique can be applied to study the properties of four-stranded nucleic acid structures that are formed by G-rich oligonucleotides.

The Journal of Chemical Physics, 1968
An exact statistical-mechanical treatment is given for the nearest-neighbor coupled model of DNA, allowing for the difference in bonding stability of the two base pairs, adenine–thymine and gaunine–cytosine. Treatments are given for random as well as pair-correlated sequences, both for finite and infinite degrees of polymerization.

SAXS Studies of Polymer Melting: Models for Surface Melting, Sequential Melting, and Stack Melting
Macromolecules, 2003Melting of semicrystalline polymers typically occurs over a temperature range of 10 °C or more, throughout which the long period L increases by 50%−100%. Less recognized is the evolution of the small-angle X-ray scattering (SAXS) pattern from peaked to monotonic before the final stages of melting.

Crystal-melt and melt-vapor interfaces of nickel
Physical Review B, 1989The equilibrium crystal-to-melt interfaces for Ni(001) and Ni(111) and themelt-to-vapor interface are investigated at the melting point, with use ofmolecular-dynamics simulations and the embedded-atom method. The meltingtemperature of nickel determined from these simulations is1733+-22 K, in good agreement with the experimental value.The crystal-to ...

Melting and melt structure of MgO at high pressures
Physical Review B, 1994By performing large-scale molecular-dynamics simulations of clusters of MgO we investigate the fundamental physics of melting, and the effects of pressure on melt and crystal structure along the melting curve from zero pressure to 300 GPa. We find that melting occurs at constant root-mean-squared (rms) displacements relative to the average near ...
