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...
متن کاملCalcium Isotopic Anomalies in the Allende Meteorite
We report isotopic anomalies inCa which were found in two Ca-Al-rich inclusions of the Allende meteorite. These inclusions previously had been shown to contain special anomalies for Mg and 0 which were attributed to fractionation and unknown nuclear effects. The Ca data when corrected for mass fractionation by using 4°Ca; 44Ca as a standard show nonlinear isotopic ~ffects in 48Ca of + 13.5 per ...
متن کاملStrontium Isotopic Anomalies in the Allende Meteorite
We report Sr isotope anomalies in two Ca·Al-rich inclusions (EKl-4-1 and Cl) of the Allende meteoritewhichalsocontainanomaliesin 0, Mg, Ca, Ba, Nd and Sm. The Sr effects correspond to 84 Sr or 88 Sr deficits of 3.2"too and 0.8%o or to 86 Sr excesses of 1.6%o and 0.4"too. Although it cannot be ascertained in which isotope the anomalies reside, arguments based on the 8 7 Sr abundance indicate tha...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Spatially resolved organic analysis of the allende meteorite.
The distribution of polycyclic aromatic hydrocarbons(PAHs) in the Allende meteorite has been probed with two-step laser desorption/laser multiphoton ionization mass spectrometry. This method allows direct in situ analysis with a spatial resolution of 1 square millimeter or better of selected organic molecules. Spectra from freshly fractured interior surfaces of the meteorite show that PAH conce...
