    Crystal structure of sinhalite MgAlBO4 under high pressure 
    Santamaría Pérez, David; Errandonea, Daniel; Gomis, O.; Sans Tresserras, Juan Ángel; Pereira, A. L. J.; Manjón Herrera, Francisco Javier; Popescu, Catalin; Rodríguez Hernández, Plácida; Muñoz, Alfonso (American Chemical Society, 2015-03-26)
    We report on high-pressure angle-dispersive X-ray diffraction data up to 27 GPa for natural MgAlBO4 sinhalite mineral and ab initio total energy calculations. The experimental bulk modulus of sinhalite is B-0 = 171(3) GPa ...

    Structural study of pure silica and Ge-containing zeolite ITQ-24 
    Jorda Moret, Jose Luis; Cantin Sanz, Angel; Corma Canós, Avelino; Díaz Cabañas, Mª José; Leiva Herrero, Sandra; Moliner Marin, Manuel; Rey Garcia, Fernando; Sabater Picot, Mª José; Valencia Valencia, Susana (Oldenbourg Wissenschaftsverlag, 2007)
    [EN] The possibility to obtain zeolite ITQ-24 in a wide Si/Ge range of compositions have made possible to study the preferential location of Ge atoms in the zeolitic framework. Also, it has allowed studying the effect ...
