Earth’s inner core (IC), which accounts for less than 1% of the Earth’s volume, is a time capsule of our planet’s history1,2. As the IC grows, the latent heat and light elements released by the solidification process drive the convection of the liquid outer core3,4, which, in ...

Although the vp of the two-phase mixture is not accurate enough to constrain the light element content in the core due to a lack of suitable wave velocity data for Fe–Ni–Si alloys under high pressure and temperature conditions, the averaged vp for the two-phase mixture at 330 GPa and...
They found that for ∼7 wt.% silicon, the combination of temperatures over 4000 K and light element enrichment acted to make the face-centred-cubic (fcc) phase thermodynamically stable at core conditions, while the hcp structure remained the stable phase at lower pressures and temperatures. ...

Correspondingly, the 1H NMR spectrum of this O-deacylated LPS sample showed the characteristic pattern in the low-field region (5.0-6.0 ppm) for the LPS tri-heptose inner-core element (HepII, 5.76 ppm; HepI/HepIII, 5.16/5.15 ppm) of H. influenzae (FIG. 4) (Risberg et al., Eur. J...
[1] The nature of light element(s) in the core holds key to our understanding of Earth's history of accretion and differentiation, but the core composition remains poorly constrained. Carbon has been proposed to be a major constituent of the inner core, with broad implications for the global...
A high performance golf ball includes a resin inner core, a rubber outer core, and a cover. The resin inner core is made of a blend of highly neutralized polymers and a low flexural
