The structure of iron under the conditions of the Earth's inner core, Geophys. Res. Lett., 26, 1231-1234.Lidunka, Vocadla,John Brodholtet al.The Structure of iron under the condition of the Earth‘s inner—core.
Seismological studies, suggest that there is 3-4% anisotropy of P-waves in the Earth's inner core. Hexagonal closed-packed solid iron has been proposed to be the major constituent of the inner core, but a lack of knowledge about the elastic properties of this phase at inner-core pressures...
The Earth’s inner core comprises iron-nickel alloys with light elements. However, there is no clarity on the phase properties of these alloys. Here we show phase relations and equations of state of iron–nickel and iron–nickel–silicon alloys up to 186 gigapascals and 3090 kelvin. An ordere...
Earth's coreHigh pressureShock wavemelting temperatureThe Earth's core consists of iron as the major component. The melting point of iron at the inner core boundary constrains the thermal structure and solidification of the Earth's core. However, the current estimation of the melting temperature ...
Effect of light elements on the sound velocities in solid iron: Implications for the composition of Earth's core Authors: Guillaume Fiquet, Matteo D'Astuto, James Badro … In situ X-ray diffraction studies of iron to Earth-core conditions Authors: Russell J Hemley, Maddury Somayazulu, Yanzha...

Iron is thought to be the main constituent of Earth's inner core. However, the bulk properties and crystalline structure of Fe at such extreme physical conditions remain uncertain. The hexagonal-close-packed (hcp) phase of iron has been proposed as a likely stable phase in the inner core by...
Remnants of a liquid layer of magma near Earth's core, formed in the first few hundred million years of the planet's history, may still persist today as odd anomalies in the mantle. Epi and Tongoa: How two cultures diverged after an island-splitting volcanic eruption PhysOrg - March 18,...
Since iron is an abundant material, a low-cost catalyst can be fabricated. The H2O2 consumption is dependent on both the target pollutant concentrations and the concentration of dissolved organic matter (DOM) in the wastewater influent (effects of DOM on this process will be discussed in a ...
