BX90: a new diamond anvil cell design for X-ray diffraction and optical measurements.

• Innokenty Yu Kantor, Vitali B Prakapenka, +5 authors Leonid Dubrovinsky
• The Review of scientific instruments
• 2012

We present a new design of a universal diamond anvil cell, suitable for different kinds of experimental studies under high pressures. Main features of the cell are an ultimate 90-degrees symmetrical… (More)

Superhard semiconducting optically transparent high pressure phase of boron.

• Evgeniya Zarechnaya, Leonid Dubrovinsky, +14 authors Sergei I Simak
• Physical review letters
• 2009

An orthorhombic (space group Pnnm) boron phase was synthesized at pressures above 9 GPa and high temperature, and it was demonstrated to be stable at least up to 30 GPa. The structure, determined by… (More)

Sound velocities of bridgmanite from density of states determined by nuclear inelastic scattering and first-principles calculations

• Catherine McCammon, Razvan Caracas, +7 authors Leonid Dubrovinsky
• 2016

Sound velocities of bridgmanite measured in the laboratory are a key to deciphering the composition of the lower mantle. Here, we report Debye sound velocities determined using nuclear inelastic… (More)

Effect of iron oxidation state on the electrical conductivity of the Earth's lower mantle.

• Vasily Potapkin, Catherine McCammon, +8 authors Leonid Dubrovinsky
• Nature communications
• 2013

Iron can adopt different spin states in the lower mantle. Previous studies indicate that the dominant lower-mantle phase, magnesium silicate perovskite (which contains at least half of its iron as… (More)

Portable double-sided laser-heating system for Mössbauer spectroscopy and X-ray diffraction experiments at synchrotron facilities with diamond anvil cells.

• Ilya Kupenko, Leonid Dubrovinsky, +12 authors Marco A. Merlini
• The Review of scientific instruments
• 2012

The diamond anvil cell (DAC) technique coupled with laser heating is a major method for studying materials statically at multimegabar pressures and at high temperatures. Recent progress in… (More)

Molecular characterization of the replicon of the Pediococcus pentosaceus 43200 pediocin A plasmid pMD136.

• Anastasia Kantor, Thomas J. Montville, Anahit Mett, Roni Shapira
• FEMS microbiology letters
• 1997

The pediocin A-encoding plasmid of Pediococcus pentosaceus 43200, pMD136, was characterized by restriction enzyme analysis. Analysis of its replicon was facilitated by the construction of a probe… (More)

Non-unitary Scattering Theory against Generalized Unitary Scattering Theory

• Jacek A. Jakiel, Anastasia Kantor
• 2017

Comparison of non-unitary and generalized unitary scattering theories is done by means of nuclear monodromy (equivalence of Schrödinger and Maxwell time-independent equations), tunneling and… (More)

High-pressure structural studies of eskolaite by means of single-crystal X-ray diffraction

• Anastasia Kantor, Innokenty Yu Kantor, +4 authors Leonid Dubrovinsky
• 2012

The structural behavior of Cr2O3 was investigated up to ~70 GPa using single-crystal X-ray diffraction under a quasi-hydrostatic pressure (neon pressure medium) at room temperature. The crystal… (More)
