New insulating low temperature phase in dense hydrogen: The phase diagram to 421 GPa

In the quest to make metallic hydrogen at low temperatures a rich number of new phases have been found and the highest pressure ones have somewhat flat phase lines, around room temperature. We have studied hydrogen to static pressures of 421±13 GPa in a diamond anvil cell and down to liquid helium temperatures, using infrared spectroscopy. We report a new phase at a pressure of !356±13 GPa and ...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

The Phase Diagram of MgO from Density Functional Theory and Molecular Dynamics Simulations

We use rst principles methods (no empirical parameters) to establish the phase diagram for the B1(NaCl), B2(CsCl), and liquid phases of MgO. We used density functional theory (DFT) with the generalized gradient approximation (GGA) to predict the equation-of-state [volume versus pressure (V (P ))] at 0 K for MgO in the low density B1 (NaCl) phase and the high density B2 (CsCl) phase. We nd a pre...

Chromomagnetic Instability and Gluonic Phase in Dense Neutral Quark Matter

The phase structure of hot and/or dense QCD is one of the most exciting current topics in the field of strong interactions. In particular, the properties of cold and dense quark matter are of great interest in astrophysics and cosmology; it is now widely accepted that, at moderate densities of relevance for the interior of compact stars, quark matter is a color superconductor and has a rich pha...
