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.

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.

Melting of clusters and melting
Physical Review A, 1984A model is presented for the melting and freezing behavior of finite clusters. The model has the property---and suggests that some real clusters may so behave---that the rigid, solidlike form is the only thermodynamically stable form below a "freezing" temperature ${T}_{f}$, that the solidlike form may coexist with a nonrigid, liquidlike form within a ...

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 ...

Journal of Psychiatric and Mental Health Nursing, 1999
A description of the author's psychiatric breakdown is offered, and a discussion of how such wounded experiences can help in mental health work. Wounded healers are currently under attack in the National Health Service in the UK, following the Allitt affair.

Melting and dissolution of high‐melting alloys in steel melts
Steel Research, 2000About one year ago a booklet by Liuyi Zhang and Franz Oeters titled Melting and mixing of alloying agents in steel melts. Methods of mathematical modelling was published [1]. On pages 45, 46‐48, 49‐51 of this booklet numerical calculations are presented, inter alia, for the simultaneous melting and dissolution of high‐melting alloys in steel melts, and

Melting and melt segregation processes controlling granitic melt composition
American MineralogistAbstract Several important processes in the petrogenesis of granite are still debated due to a poor understanding of complex interactions between minerals during the melting and melt segregation processes. To promote an improved understanding of the mineral-melt relationships, we present a systematic petrographic and geochemical analysis

SEG-MELT (electric glass melting)
Conference Record of the IEEE Industry Applications Society Annual Meeting, 2003The author introduces segmented melting, the separation of batch from cullet. An overview of the problems and their recommended solutions are presented, with a potential container glass application given as an example. It is suggested that the cullet be given greater consideration in the glass-melting process.

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.

How ice ‘melts’ below its melting point
Physics World, 2005Water is the most important chemical substance on Earth, but there is still much that we do not understand about it. Everyone knows that ice melts when it is heated above 273 K or 0°C at atmospheric pressure, and that liquid water freezes when it is cooled below this temperature.
