Journal ArticleDOI
BX90: A new diamond anvil cell design for X-ray diffraction and optical measurements
Innokenty Kantor,Vitali B. Prakapenka,A. Kantor,Przemyslaw Dera,Alexander Kurnosov,Stanislav V. Sinogeikin,Natalia Dubrovinskaia,Leonid Dubrovinsky +7 more
TL;DR: Main features of the cell are an ultimate 90-degrees symmetrical axial opening and high stability, making the presented cell design suitable for a whole range of techniques from optical absorption to single-crystal X-ray diffraction studies, also in combination with external resistive or double-side laser heating.
Journal ArticleDOI
Gas hydrates of argon and methane synthesized at high pressures : Composition, thermal expansion, and self-preservation
A. G. Ogienko,Alexander Kurnosov,Andrey Yu. Manakov,Eduard G. Larionov,A I Ancharov,M.A. Sheromov,Anatoly N. Nesterov +6 more
TL;DR: A good agreement with the refinement of the argon hydrate structure using neutron powder diffraction data is shown and helps to rationalize the evolution of hydrate structures in the Ar-H(2)O system at high pressures.
Journal ArticleDOI
A novel gas-loading system for mechanically closing of various types of diamond anvil cells.
Alexander Kurnosov,Innokenty Kantor,Tiziana Boffa-Ballaran,Sven Lindhardt,Leonid Dubrovinsky,Alexei Kuznetsov,Beat H. Zehnder +6 more
TL;DR: A simple in operation, safe, and universal gas-loading system has been designed and constructed to simplify the loading procedure up to the "three-button" mode.
Journal ArticleDOI
Effect of chemistry on the compressibility of silicate perovskite in the lower mantle
Tiziana Boffa Ballaran,Alexander Kurnosov,Konstantin Glazyrin,Daniel J. Frost,Marco Merlini,Marco Merlini,Michael Hanfland,Razvan Caracas +7 more
TL;DR: In this paper, the effect of different chemical substitutions on the compression mechanism of perovskite and on its equation of state (EoS) was examined by means of synchrotron X-ray diffraction in diamond anvil cells with He as pressure transmitting medium from room pressure up to 75 GPa.
Journal ArticleDOI
X-ray diffraction and Mössbauer spectroscopy study of fcc iron hydride FeH at high pressures and implications for the composition of the Earth's core
O. Narygina,Leonid Dubrovinsky,Catherine McCammon,Alexander Kurnosov,Innokenty Kantor,Vitali B. Prakapenka,Natalia Dubrovinskaia +6 more
TL;DR: The phase fcc FeHx was synthesized at pressures over 30 GPa and temperatures over 1600(50) K as mentioned in this paper, and at room temperature this iron hydride is stable at pressures from 19 GPa up to at least 68 GPa.
