Bargueño, Pedro ; Pérez de Tudela, Ricardo ; Miret Artés, Salvador ; Gonzalo Fonrodona, Isabel | Royal Society of Chemistry | 2011Interactions which do not conserve parity might influence chiral compounds giving rise to a parity violating energy difference (PVED) that might have affected the evolution towards homochirality. However, this tiny effect predicted by electrowea[...]texto impreso
Viedma Molero, Cristóbal ; Noorduin, Wim L. ; Ortiz Menéndez, José Eugenio ; Torres, Trinidad ; Cintas Moreno, Pedro | Royal Society of Chemistry | 2011A straightforward unprecedented sublimation protocol that reveals both conversion of a racemic compound into a racemic conglomerate and subsequent enantioenrichment has been developed for the proteinogenic amino acid valine. The phenomenon has b[...]texto impreso
Montalvo-Quirós, Sandra ; Aragoneses-Carzorla, Guillermo ; García-Alcalde, Laura ; Vallet Regí, María ; González, Blanca ; Luque-García, José L. | Royal Society of Chemistry | 2019-02-12The aim of the present work is to provide an approach to safely deliver silver nanoparticles (AgNPs) as cytotoxic agents into cancer cells, and to provide a deeper insight into the cellular mechanisms affected by such targeted delivery. The use [...]texto impreso
Scharl, Tobías ; Ferrer Ruiz, Andrés ; Saura Sanmartin, Adrián ; Rodríguez Perez, Laura ; Herranz, M. Ángeles ; Martín, Nazario ; Guldi, Dirk M. | Royal Society of Chemistry | 2019Water-soluble fluorescent graphene quantum dots have been successfully prepared through a top-down approach, that is, starting with graphite, and covalently functionalizing it with p-extended tetrathiafulvalene. Charge transfer investigations re[...]texto impreso
Turdean-Ionescu, Claudia ; Stevensson, Baltzar ; Grins, Jekabs ; Izquierdo Barba, Isabel ; García, Ana ; Arcos Navarrete, Daniel ; Vallet Regí, María ; Eden, Mattias | Royal Society of Chemistry | 2015Silicate-based bioactive glasses exhibit bone-bonding properties due to the formation of a hydroxycarbonate apatite (HCA) layer at the glass surface on its contact with living tissues. This bone-healing process is triggered by ionic exchange bet[...]texto impreso
Reinares Fisac, Daniel ; Veintemillas Verdaguera, S. ; Fernández-Díaz, Lourdes | Royal Society of Chemistry | 2017The interaction of Sepia officinalis cuttlefish bone, made of aragonitic CaCO3, with (NH4)2HPO4 boiling solutions produces porous carbonate-bearing hydroxyapatite (Ca10(PO4)6(OH)2) scaffolds with extremely large specific surface area. Percentage[...]texto impreso
Guisasola, Eduardo ; Baeza, Alejandro ; Talelli, Marina ; Arcos Navarrete, Daniel ; Vallet Regí, María | Royal Society of Chemistry | 2016-04-25Stimuli-responsive devices are novel tools widely studied in the nanomedicine research field. In this work, magnetic-responsive mesoporous silica nanoparticles (MMSNs) were coated with an engineered thermoresponsive co-polymer. Magnetic cores ar[...]texto impreso
Cicuendez, Monica ; Portoles, Pilar ; Montes Casado, María ; Izquierdo-Barba, Isabel ; Vallet Regí, María ; Portolés Pérez, María Teresa | Royal Society of Chemistry | 2014-06-14The interaction of new nanocomposite mesoporous glass/hydroxyapatite (MGHA) scaffolds with immune cells involved in both innate and acquired immunity has been studied in vitro as an essential aspect of their biocompatibility assessment. Since th[...]texto impreso

T. | Royal Society of Chemistry | 2016Silicon substituted and nanocrystalline hydroxyapatites have attracted the attention of many researchers due to their up-regulation in osteoblast cell metabolism and enhanced bioreactivity, respectively. On the other hand, the biomaterial succes[...]texto impreso
Baeza García, Alejandro ; Castillo Romero, Rafael ; Torres Pardo, Almudena ; Gonzalez Calvet, J. M. ; Vallet Regí, María | Royal Society of Chemistry | 2017-02-17The use of nanoparticles able to transport drugs, in a selective and controlable manner, directly to diseased tissues and cells have improved the therapeutic arsenal for addressing unmet clinical situations. In the recent years, a vast number of[...]texto impreso
Álvarez, L. ; Costa, F. ; Lozano, A. I. ; Oller, J. C. ; Muñoz, A. ; Blanco Ramos, Francisco ; Limao-Vieira, P. ; White, R. D. ; Brunger, M. J. ; García, G. | Royal Society of Chemistry | 2020-06-28Absolute total electron scattering cross sections (TCS) for nitrobenzene molecules with impact energies from 0.4 to 1000 eV have been measured by means of two different electron-transmission experimental arrangements. For the lower energies (0.4[...]texto impreso
Viedma Molero, Cristóbal ; Ortiz Menéndez, José Eugenio ; Torres Pérez-Hidalgo, Trinidad José de ; Cintas Moreno, Pedro | Royal Society of Chemistry | 2012A real amplification of an initial enantiomeric excess can be detected when two amino acids are sublimed at high temperature, even if one of the components is a racemic compound that does not convert into a conglomerate by sublimationtexto impreso
We analyze theoretically the entanglement between two non-planar and light identical molecules (e.g., pyramidal NH3) that present inversion doubling due to the internal spatial inversion of their nuclear conformations by tunneling. The peculiari[...]texto impreso
Forjanes, Pablo ; Gómez Barreiro, Juan ; Morales, Juan ; Astilleros García-Monge, José Manuel ; Fernández Díaz, Lurdes | Royal Society of Chemistry | 2020Epitactic crystal growth plays a main role in the development of mineral processes and in the synthesis of advanced materials. Celestite (SrSO4) forms epitactic overgrowths on anhydrite (CaSO4) (100), (010) and (001) surfaces upon interacting wi[...]
