Inositol, 1,2,3,4,5,6-hexahydroxycyclohexane, exists in nine stereoisomers with different crystal structures and melting points. In a previous paper on the relationship between the melting points of the inositols and the hydrogen-bonding patterns in their crystal structures [Simperler et al. (2006 ▶). CrystEngComm 8, 589], it was noted that although all inositol crystal structures known at that...

Differential magneto-optical imaging of the vortex-lattice-melting process in Bi(2)Sr(2)CaCu(2)O(8) crystals reveals unexpected effects of quenched disorder on the broadening of the first-order phase transition. The melting patterns show that the disorder-induced melting landscape T(m)(H,r) is not fixed, but rather changes dramatically with varying field and temperature along the melting line. ...

The Wang-Landau Monte Carlo approach is applied to the coil-globule and melting transitions of off-lattice flexible homopolymers. The solid-liquid melting point and coil-globule transition temperatures are identified by their respective peaks in the heat capacity as a function of temperature. The melting and theta points are well separated, indicating that the coil-globule transition occurs sep...

To investigate the effect of adsorbates on structural transitions in small palladium aggregates, we have performed molecular dynamics simulations of cluster “melting” in presence of atomic hydrogen. Intriguing questions are how the exposure to hydrogen modifies the metal-metal interaction, and whether hydrogen could lower the onset of melting. Various structural and caloric methods were used to...

UNLABELLED MELTING computes the enthalpy and entropy of an oligonucleotide duplex helix-coil transition, and then its melting temperature. The program uses the method of nearest-neighbours. The set of thermodynamic parameters can be easily customized. The program provides several correction methods for the concentration of salt. MELTING is a free program, available at no cost and open-source. P...

BACKGROUND Common methods for identification of DNA sequence variants use gel electrophoresis or column separation after PCR. METHODS We developed a method for sequence variant analysis requiring only PCR and amplicon melting analysis. One of the PCR primers was fluorescently labeled. After PCR, the melting transition of the amplicon was monitored by high-resolution melting analysis. Differen...

The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...

Fe–Mg exchange is the most important solid solution involved in for Fe–Mg exchange between the coexisting crystalline phases and melt, KdFe–Mg, show a relatively simple and predictable behaviour partial melting of spinel lherzolite, and the system CaO– MgO–Al2O3–SiO2–FeO (CMASF) is ideally suited to explore with pressure and temperature: the coefficients for olivine and spinel do not show signi...

In this study, metal behavior in ash-melting and municipal solid waste (MSW) gasiWcation-melting facilities were investigated. Eight ash-melting and three MSW gasiWcation-melting facilities with a variety of melting processes and feedstocks were selected. From each facility, melting furnace Xy ash (MFA) and molten slag were sampled, and feedstock of the ash-melting processes was also taken. For...

Video microscopy is employed to study the melting behaviors of multilayer colloidal crystals composed of diameter-tunable microgel spheres confined between two walls. We systematically explore film thickness effects on the melting process and on the phase behaviors of single crystal and polycrystalline films. Thick films (>4 layers) are observed to melt heterogeneously, while thin films (≤4 lay...
