Pressure-induced decomposition of Bi14WO24
E. Karaca, D. Santamaria-Perez, A. Otero-de-la-Roza +5
We present a study of the high-pressure behaviour Bi14WO24, a high oxide ion conductor member of the Bi2O3-WO3 binary system. The tetragonal polymorph of Bi14WO24 was studied under…
X-ray thermal diffuse scattering as a texture-robust temperature diagnostic for dynamically compressed solids
P. G. Heighway, D. J. Peake, T. Stevens +119
We present a model of x-ray thermal diffuse scattering (TDS) from a cubic polycrystal with an arbitrary crystallographic texture, based on the classic approach of Warren. We compar…
Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
Experimental and theoretical confirmation of an orthorhombic phase transition in niobium at high pressure and temperature
Daniel Errandonea, Leonid Burakovsky, Dean L. Preston +8
Compared to other body-centered cubic (bcc) transition metals Nb has been the subject of fewer compression studies and there are still aspects of its phase diagram which are unclea…
Comparative study of the high-pressure behavior of ZnV2O6, Zn2V2O7, and Zn3V2O8
D. Diaz-Anichtchenko, D. Santamaria-Perez, T. Marqueno +7
We report a study of the high-pressure structural behavior of ZnV2O6, Zn2V2O7, and Zn3V2O8, which has been explored by means of synchrotron powder x-ray diffraction. We found that…
Experimental and theoretical study of SbPO4 under compression
André Luis de Jesus Pereira, David Santamaría-Pérez, Rosário Vilaplana +14
SbPO4 is a complex monoclinic layered material characterized by a strong activity of the non-bonding lone electron pair (LEP) of Sb. The strong cation LEP leads to the formation of…
Exploring the behavior of vanadium under high-pressure and high-temperature conditions
D. Errandonea, S. G. MacLeod, L. Burakovsky +4
We report a combined experimental and theoretical study of the melting curve and the structural behavior of vanadium under extreme pressure and temperature. We performed powder x-r…
Pressure impact on the stability and distortion of the crystal structure of CeScO3
Daniel Errandonea, David Santamaria-Perez, Domingo Martinez-Garcia +5
The effects of high pressure on the crystal structure of orthorhombic (Pnma) perovskite type cerium scandate have been studied in situ under high pressure by means of synchrotron x…
Exploring the high-pressure behavior of the three known polymorphs of BiPO4: Discovery of a new polymorph
D. Errandonea, O. Gomis, D. Santamaria-Perez +6
We have studied the structural behavior of bismuth phosphate under compression. We performed x-ray powder diffraction measurements up to 31.5 GPa and ab initio calculations. Experi…
Compressibility and structural stability of ultra-incompressible bimetallic interstitial carbides and nitrides
D. Errandonea, J. Ruiz-Fuertes, J. A. Sans +4
We have investigated by means of high-pressure x-ray diffraction the structural stability of Pd2Mo3N, Ni2Mo3C0.52N0.48, Co3Mo3C0.62N0.38, and Fe3Mo3C. We have found that they remai…
Zircon to monazite phase transition in CeVO4
V. Panchal, S. Lopez-Moreno, D. Santamaria-Perez +6
X-ray diffraction and Raman-scattering measurements on cerium vanadate have been performed up to 12 and 16 GPa, respectively. Experiments reveal that at 5.3 GPa the onset of a pres…
High-pressure x-ray diffraction study of bulk and nanocrystalline PbMoO4
D. Errandonea, D. Santamaria-Perez, V. Grover +2
We studied the effects of high-pressure on the crystalline structure of bulk and nanocrystalline scheelite-type PbMoO4. We found that in both cases the compressibility of the mater…
New high-pressure phase of HfTiO4 and ZrTiO4 ceramics
Daniel Errandonea, David Santamaria-Perez, Tatiana Bondarenko +1
We studied the high-pressure effects on the crystalline structure of monoclinic HfTiO4 and ZrTiO4. We found that the compressibility of these ceramics is highly non-isotropic, bein…
