High-pressure phase of brucite stable at Earth's mantle transition zone and lower mantle conditions.
We investigate the high-pressure phase diagram of the hydrous mineral brucite, Mg(OH)2, using structure search algorithms and ab initio simulations. We predict a high-pressure phase stable at pressure and temperature conditions found in cold subducting slabs in Earth's mantle transition zone and lower mantle. This prediction implies that brucite can play a much more important role in water tran...
متن کاملThe Conditions of the Violations of Le Chatlier’s Principle in Gas Reactions at Constant T and P
Le Chatelier's principle is used as a very simple way to predict the effect of a change in conditions on a chemical equilibrium. . However, several studies have reported the violation of this principle, still there is no reported simple mathematical equation to express the exact condition of violation in the gas phase reactions. In this article, we derived a simple equation for the violation of...

متن کاملHigh p T Hadron Spectra at High Rapidity
We report the measurement of charged hadron production at different pseudo-rapidity values in deuteron+gold as well as proton-proton collisions at √ sNN = 200GeV at RHIC. The nuclear modification factors RdAu and Rcp are used to investigate new behaviors in the deuteron+gold system as function of rapidity and the centrality of the collisions respectively.
متن کاملPuzzles at High P T at Rhic and Their Resolution *
Several puzzles about the data at high pT in heavy-ion collisions are listed. The resolution of them all is given in the framework of parton recombination. More specifically, it is the recombination of the soft and semi-hard shower partons that enhances the region 3 < pT < 9 GeV/c, and gives rise to the large p/π ratio in AuAu collisions. The Cronin effect can be explained in terms of final-sta...
