    Complex high-pressure polymorphism of barium tungstate 
    Gomis Hilario, Oscar; Sans, J. A.; Lacomba-Perales, R.; Errandonea, D.; Meng, Y.; Chervin, J. C.; Polian, A. (American Physical Society, 2012-08-27)
    We have studied BaWO 4 under compression at room temperature by means of x-ray diffraction and Raman spectroscopy. When compressed with neon as a pressure-transmitting medium (quasihydrostatic conditions), we found that ...

    High-pressure crystal structure, lattice vibrations, and band structure of BiSbO4 
    Errandonea, Daniel; Muñoz, Alfonso; Rodríguez-Hernández, Plácida; Gomis, O.; Achary, S. Nagabhusan; Popescu, Catalin; Patwe, Sadeque J.; Tyagi, Avesh J. (American Chemical Society, 2016-05-16)
    The high-pressure crystal structure, lattice-vibrations HP crystal structure, lattice vibrations, and band , and electronic band structure of BiSbO4 were studied by ab initio simulations. We also performed Raman spectroscopy, ...

    Ordered helium trapping and bonding in compressed arsenolite: Synthesis of As4O6 2He 
    Sans Tresserras, Juan Ángel; Manjón Herrera, Francisco Javier; Popescu, Catalin; Cuenca Gotor, Vanesa Paula; Gomis, Oscar; Muñoz, Alfonso; Rodríguez Hernández, Plácida; Contreras García, Julia; Pellicer Porres, Julio; Pereira, A.L.J.; Santamaría Pérez, David; Segura, Alfredo (American Physical Society, 2016-02)
    Compression of arsenolite has been studied from a joint experimental and theoretical point of view. Experiments on this molecular solid at high pressures with different pressure-transmitting media have been interpreted ...
