The COMPRES/GSECARS gas-loading system for diamond anvil cells at the Advanced Photon Source (2008, methodology): “Here, we present preliminary X-ray diffraction data of single-crystal MgO to 110 GPa, about twice the pressure of previous compression studies carried out with helium pressure-transmitting media [9,10].”
Deformation of polycrystalline MgO at pressures of the lower mantle (2002, methodology): “Figure 7 presents the elastic moduli we obtained from experiment 1 using pressures deduced from the hydrostatic EOS of MgO [Speziale et al., 2001] and uniaxial stress values from Figure 6 for a = 1 (Reuss bound) and a = 0.5 (Hill average) along with results from Brillouin spectroscopy [Zha et al.,…”

Thermodynamics of mantle minerals – I. Physical properties (2005, background): “Previous theoretical and experimental studies have also found that q decreases with compression (Agnon & Bukowinski 1990; Speziale et al. 2001).”
Postperovskite phase transition and its geophysical implications (2006, background): “On the other hand, if the pressures were determined from the MgO pressure marker [Speziale et al., 2001] mixed together with Au, the boundary was located at 119 GPa and 2400 K with a slope of +11.5 MPa K 1.”
Cell assemblies for reproducible multi-anvil experiments (the COMPRES assemblies) (2012, methodology): “An initial set of measurements at APS was done with an MgO + W standard as the sample, using the equations of state of Speziale et al. (2001) for MgO and Hixson and Fritz (1992) for W.”
Density-Functional Perturbation Theory for Quasi-Harmonic Calculations (2011, positive): “…et al. 2008), obtained by means of renormalized phonons and QHA, has been used as a new pressure calibration to re-evaluate the high pressure – high temperature phase boundary in MgSiO3 and Mg2SiO4 minerals using experimental data from (Fei et al. 2004, Hirose et al. 2006, Speziale et al. 2001).”
Experimentally determined postspinel transformation boundary in Mg2SiO4 using MgO as an internal pressure standard and its geophysical implications (2004, neutral): “[22] The use of the MgO scale of Speziale et al. [2001] as a reference scale is also practical because the existing high-pressure and high-temperature data produced by quenching experiments in the last two decades require only a minimal pressure correction.”
