Reflecting Laser-Driven Shocks in Diamond in the Megabar Pressure Range
(Chinese Laser Press and Cambridge University Press, 2021-01-08)
In this work we present experimental results on the behavior of diamond at megabar pressure. The experiment was performed using the PHELIX facility at GSI in Germany to launch a planar shock into solid multi-layered diamond ...
The stochastic self-consistent harmonic approximation: calculating vibrational properties of materials with full quantum and anharmonic effects
(IOP Publishing Ltd, 2021-07-13)
[EN] The efficient and accurate calculation of how ionic quantum and thermal fluctuations impact
the free energy of a crystal, its atomic structure, and phonon spectrum is one of the main
challenges of solid state physics, ...
Quantum anharmonic enhancement of superconductivity in P63/mmc ScH6 at high pressures: A first-principles study
(AIP Publishing, 2021-11-05)
Making use of first-principles calculations, we analyze the effect of quantum ionic fluctuations and lattice anharmonicity on the crystal structure and superconductivity of P63/mmc ScH6 in the 100–160 GPa pressure range ...
Generation of laser-driven shocks and their use to study simple compounds at high pressure
(2021-12-15)
El conocimiento profundo y la comprensión de la ecuación de estado de materiales simples como el carbono y el agua en el régimen de materia densa cálida (WDM) es esencial para el modelado de la estructura interna de muchos ...
Black metal hydrogen above 360 GPa driven by proton quantum fluctuations
(Nature Physics, 2020-09-07)
Hydrogen metallization under stable conditions is a major quest for realizing the first room temperature su-
perconductor. Recent low-temperature experiments report different metallization pressures, varying from 360GPa ...
Quantum crystal structure in the 250-kelvin superconducting lanthanum hydride
(Springer Nature, 2020-02-05)
The discovery of superconductivity at 200 kelvin in the hydrogen sulfide system at high pressures demonstrated the potential of hydrogen-rich materials as high-temperature superconductors. Recent theoretical predictions ...
Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
Modifying the magnetic response of magnetotactic bacteria: incorporation of Gd and Tb ions into the magnetosome structure
(Royal Society of Chemistry, 2022-06)
Magnetotactic bacteria Magnetospirillum gryphiswaldense MSR-1 biosynthesise chains of cube-octahedral magnetosomes, which are 40 nm magnetite high quality (Fe3O4) nanoparticles. The magnetic properties of these crystalline ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
Investigating the Size and Microstrain Influence in the Magnetic Order/Disorder State of GdCu2 Nanoparticles
(MDPI, 2020-06-05)
A series of GdCu [Math Processing Error] nanoparticles with controlled sizes ranging from 7 nm to 40 nm has been produced via high-energy inert-gas ball milling. Rietveld refinements on the X-ray diffraction measurements ...
