High-pressure melting curve of hydrogen.

The melting curve of hydrogen was computed for pressures up to 200 GPa, using molecular dynamics. The inter- and intramolecular interactions were described by the reactive force field (ReaxFF) model. The model describes the pressure-volume equation of state solid hydrogen in good agreement with experiment up to pressures over 150 GPa, however the corresponding equation of state for liquid devia...

Melting curve and fluid equation of state of carbon dioxide at high pressure and high temperature.

The melting curve and fluid equation of state of carbon dioxide have been determined under high pressure in a resistively heated diamond anvil cell. The melting line was determined from room temperature up to 11.1+/-0.1 GPa and 800+/-5 K by visual observation of the solid-fluid equilibrium and in situ measurements of pressure and temperature. Raman spectroscopy was used to identify the solid ph...

High 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...

Melting curve and high-pressure chemistry of formic acid to 8 GPa and 600 K.

We have determined the melting temperature of formic acid (HCOOH) as a function of pressure to 8.5 GPa using infrared absorption spectroscopy, Raman spectroscopy and visual observation of samples in a resistively heated diamond-anvil cell. The experimentally determined incongruent melting curve compares favorably with a two-phase thermodynamic model. Decomposition reactions were observed above ...

High-resolution melting-curve analysis of ligation-mediated qPCR;

25 A single-tube method – ligation mediated real-time PCR high-resolution melt analysis 26 (LMqPCR HRMA) – was modified for rapid typing of ESKAPE-pathogens. A 97 % 27 agreement (60/62 isolates) was achieved in comparison to PFGE which indicates that 28 LMqPCR HRMA is a rapid and accurate screening tool to monitor for nosocomial outbreaks. 29 on O cber 1, 2017 by gest ht://jcm .sm .rg/ D ow nla...
