Marinescu, G.; Andruh, M.; Lescouëzec, R.; Muñoz Roca, María Del Carmen; Cano, J.; Lloret, F.; Julve, M. (The Royal Society of Chemistry, 2000-07)

[EN] The new complexes of formula AsPh4[Cr(phen)(ox)(2)] . H2O (1), [NaCr(phen)(ox)(2)(H2O)] . 2H(2)O (2) and {[Cr(phen)(ox)(2)](2)[Mn-2(bpy)(2)(H2O)(2)(ox)]} . 6H(2)O (3) (AsPh4 = tetraphenylarsonium cation; phen = ...
Compressibility systematics of calcite-type borates : An experimental and theoretical structural study on ABO3 (A = Al, Sc, Fe and In)

Santamaría Pérez, David; Gomis Hilario, Oscar; Sans, Juan Ángel; Ortiz, H. M.; Vegas, Ángel; Errandonea, Daniel; Ruiz-Fuertes, Javier; Martínez-García, Domingo; García-Domene, B.; Pereira, ALJ; Manjón Herrera, Francisco Javier; Rodríguez-Hernández, Placida; Muñoz, A.; Piccinelli, F.; Bettinelli, M.; Popescu, C. (American Chemical Society, 2014-02-27)

The structural properties of calcite-type orthoborates ABO(3) (A = Al, Fe, Sc, and In) have been investigated at high pressures up to 32 GPa. They were studied experimentally using synchrotron powder X-ray diffraction and ...
Compression of Silver Sulfide: X-ray Diffraction Measurements and Total-Energy Calculations

Gomis Hilario, Oscar; Santamaria Pérez, David; Chuliá-Jordaán, Raquel; Marqués, Míriam; Menendez, José M.; Ruiz-Fuertes, Javier; Sans, Juan A.; Errandonea, Daniel; Recio, José Manuel (American Chemical Society, 2012-04-24)

[EN] Angle-dispersive X-ray diffraction measurements have been performed in acanthite, Ag2S, up to 18 GPa in order to investigate its high-pressure structural behavior. They have been complemented by ab initio electronic ...
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 ...
Gated Silica Mesoporous Materials in Sensing Applications

Sancenón Galarza, Félix; Pascual, Lluís; Oroval, Mar; Aznar Gimeno, Elena; Martínez-Máñez, Ramón (Wiley Open Access, 2015-08)

[EN] Silica mesoporous supports (SMSs) have a large specific surface area and volume and are particularly exciting vehicles for delivery applications. Such container-like structures can be loaded with numerous different ...
High-pressure study of the behavior of mineral barite by X-ray diffraction

Santamaría-Pérez, D.; Gracia, L.; Garbarino, G.; Beltrán, A.; Chuliá-Jordán, R.; Gomis Hilario, Oscar; Errandonea, D.; Ferrer-Roca, Ch.; Martínez-García, D.; Segura, A. (American Physical Society, 2011-08-02)

In this paper, we report the angle-dispersive x-ray diffraction data of barite, BaSO 4, measured in a diamond-anvil cell up to a pressure of 48 GPa, using three different fluid pressure-transmitting media (methanol-ethanol ...
Responses to environmental stress in plants adapted to Mediterranean gypsum habitats

Llinares Palacios, Josep Vicent; Bautista Carrascosa, Inmaculada; Donat-Torres, María P.; Lidón, A.; Lull Noguera, Cristina; Mayoral García-Berlanga, Olga; Wankhade, Shantanu Devidas; Boscaiu, Mónica; Vicente, Óscar (Academic Press, 2015)

[EN] Gypsum areas are stressful environments inhabited by gypsophytes, plants that are exclusive for such habitats, and by plants that grow on gypsum but also on other soil types, the so-called gypsovags. To investigate ...
Silica nanoparticles functionalised with cation coordination sites and fluorophores for the differential sensing of anions in a quencher displacement assay (QDA)

Calero Rodríguez, María del Pilar; Hecht, Mandy; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Soto Camino, Juan; Vivancos, José-Luís; Rurack, Knut (Royal Society of Chemistry, 2011)

In conjunction with quenching metal ions, silica nanoparticles carrying terpyridine coordination sites and sulforhodamine B signalling units were employed for the differential fluorometric recognition of anions. © 2011 The ...
Synthesis and structure determination of a new microporous zeolite with large cavities connected by small pores
