The effect of the differential rotation of the earth inner core on the free core nutation
Geodesy and Geodynamics, 2019 Seismic observations shows that the inner core rotates faster than the mantle and the rotation axis of the inner core may not align with the rotation axis of the mantle. Free core nutation reflects core's information.

Thermal and electrical conductivity of iron at Earth's core conditions [PDF]
, 2012 The Earth acts as a gigantic heat engine driven by decay of radiogenic isotopes and slow cooling, which gives rise to plate tectonics, volcanoes, and mountain building.

Hypothesis of Piezoelectricity of Inner Core As the Origin of Geomagnetism
Data Science Journal, 2009 A novel hypothesis is proposed that assumes piezoelectricity of the inner core as the origin of geomagnetism. By high pressure, electric charge is created on the surface and at the center of the earth. Inner core rotation yields a magnetic field.

Two-phase mixture of iron–nickel–silicon alloys in the Earth’s inner core
Communications Earth & Environment, 2021 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 ...

A time-dependent Schr\"odinger equation for molecular core-hole dynamics [PDF]
, 2017 X-ray spectroscopy is an important tool for the investigation of matter. X rays primarily interact with inner-shell electrons creating core (inner-shell) holes that will decay on the time scale of attoseconds to few femtoseconds through electron ...

Elevating Leadership Effectiveness by Building Self-Awareness of Inner Dynamics [PDF]
Dyskursy o Kulturze, 2020 By improving self-awareness, leaders can elevate their effectiveness. Focusing on one’s inner dynamics constitutes a practical approach that offers a useful framework for leaders themselves as well as all the others who support them on their path ...

What Are the Finger‐Like Clouds in the Hurricane Inner‐Core Region?
Geophysical Research LettersFinger‐like km‐scale features have been observed along the inner‐edge of the eyewall of intense hurricanes. But due to the limited availability of observations, many important aspects of these features remain unknown.

Melting-induced stratification above the Earth's inner core due to convective translation [PDF]
, 2010 In addition to its global North-South anisotropy(1), there are two other enigmatic seismological observations related to the Earth's inner core: asymmetry between its eastern and western hemispheres(2-6) and the presence of a layer of reduced seismic ...

The rigidity of the Earth’s inner core
Annals of Geophysics, 2010 The evidence for the existence of significant rigidity in the Earth's inner core is summarised and discussed in the light of recent work. Quantum-mechanical calculations, based on a Thomas-Fermi-Dirac model, suggest that an earlier estimate of 3.6 × 10¹²
