Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

Earth's core is known to be metallic, with a density of about 9.90 Mg· m− 3 at the coremantle
boundary and as such is substantially denser than the surrounding mantle (5.56 Mg· m− 3 at …

Iron carbides in association with native iron, graphite, and magnetite were identified in a
crystal of diamond from the Juina area, Brazil, that contains a series of other, deep-mantle …

Earth's inner core is known to consist of crystalline iron alloyed with a small amount of nickel
and lighter elements, but the shear wave (S wave) travels through the inner core at about …

The melting points of fcc-and hcp-structured Fe 0.9 Ni 0.1 and Fe are measured up to 125
GPa using laser heated diamond anvil cells, synchrotron Mössbauer spectroscopy, and a …

We have determined the density evolution of the sound velocity of dhcp-FeHx (x≈ 1) up to
70GPa at room temperature, by inelastic X-ray scattering and by X-ray diffraction. We find …

The relative abundance of light elements in the Earth's core has long been controversial.
Recently, the presence of carbon in the core has been emphasized, because the density …

Investigations into the compositional model of the Earth, particularly the atypical
concentrations of volatile elements within the silicate portion of the early Earth, have …

We report the high‐pressure thermoelastic and vibrational thermodynamic parameters for
hexagonal close‐packed iron (ε‐Fe), based on nuclear resonant inelastic X‐ray scattering …

Sound velocities of cementite Fe 3 C have been measured up to 1.5 Mbar and at 300 K in a
diamond anvil cell using the nuclear resonant inelastic X-ray scattering (NRIXS) technique …
