The 660-kilometre seismic discontinuity is the boundary between the Earth's lower mantle
and transition zone and is commonly interpreted as being due to the dissociation of …

Recently, calcium orthocarbonate (Ca2CO4-Pnma) has been predicted to be stable under P–
T conditions of the Earth's transition zone and the lower mantle. Here, we investigate its …

The accurate equation of state (EOS) of MgO can be used as a pressure scale, but the EOS
currently used has too much uncertainty to serve as a pressure scale, especially at high …

The equations of state of MgSiO3-pyroxenes (low-pressure clinoenstatite, orthoenstatite and
high-pressure clinoenstatite) are constructed using a thermodynamic model based on the …

The equations of state of different phases in the CaSiO3 system (wollastonite,
pseudowollastonite, breyite (walstromite), larnite (Ca2SiO4), titanite-structured CaSi2O5 and …

Mantle convection is the dominant process driving the upwelling of hot materials and
subduction of cold slabs. These processes are density-dependent and influenced by post …

The determination of prayer times initially only used the direct observation method (rukyat)
namely observing the shadow of an object, then the determination of prayer times …

Based on the modified thermodynamic model, we calculate the density of olivine-pyroxene
mixtures at different proportions of molecular masses in minerals at temperatures of 1000 …

We use a simple method based on the Grover–Saxena equation of state (EOS) for
investigating the volume–pressure–temperature (V–P–T) relationships and bulk modulus of …

Teaching physics is sometimes difficult to convey without using props or visualizations.
Simulations can help teachers create and demonstrate real conditions in front of the class. In …
