Melting of ice under pressure.
The melting of ice under pressure is investigated with a series of first-principles molecular dynamics simulations. In particular, a two-phase approach is used to determine the melting temperature of the ice-VII phase in the range of 10-50 GPa. Our computed melting temperatures are consistent with existing diamond anvil cell experiments. We find that for pressures between 10 and 40 GPa, ice mel...
متن کاملDetermination of melting point of polycaprolactones under carbon dioxide pressure
Solid-Liquid-Gas equilibrium of poly-(ε-caprolactone) – carbon dioxide systems at high pressure has been determined by visual determination of the first melting point using a static apparatus. Measurements have been performed with poly-(ε-caprolactones) of three different molecular weights: 4000 g/mol, 10000 g/mol and 25000 g/mol. The determined SLG equilibrium lines show a temperature maximum ...
متن کاملMelting Temperature Depression of Solid Lipid under High Pressure Gases
The effects of high pressure gases on solid lipids were investigated by high-pressure differential scanning calorimeter (DSC). In particular, the influence of a high-pressure gas on solid-liquid and solid-solid transitions were investigated for pure tristearin and a mixture of lipids (tristearin-phosphatidylcoline-dioctilsolfosuccinate). Both of these substances are commonly used for the produc...
متن کاملPressure points
It's a familiar sight on many Caribbean and other tropical islands: as dawn breaks, the gleaming hulls of the massive cruise liners can be seen in the distance as they approach port ready to disgorge thousands of tourists for a day's sightseeing. Many islands are big enough and have sufficient infrastructure for this to pass off with minimal environmental impact but a growing number of tourists...
متن کاملHigh pressure melting of wüstite
Iron oxide (FeO) is an important component in the mineralogy of Earth's lower mantle, and possibly its core, so its phase diagram is essential to models of the planet's interior. The melting curve of wüstite, Fe0.94O, was determined up to 77 GPa and 3100 K in a laser-heated diamond anvil cell. Melting transition temperatures were identified from discontinuities in the emissivity vs. temperature...
