    • closedAccess   Freezing Capture of Polymorphic Aggregates of Bolaamphiphilic L-Valine-Based Molecular Hydrogelators 

      Nebot Carda, Vicent J.; Diaz-Oltra, Santiago; Smets, Johan; Fernández Prieto, Susana; Miravet, Juan; Escuder, Beatriu WILEY-VCH Verlag GmbH & Co. KGaA (2014-05)
      Nanostructured xerogels have been prepared by the freeze-drying of hydrogels and aggregates formed by bolaamphiphilic l-valine derivatives after aging under different environmental conditions. A wide variety of shapes and ...

    • openAccess   From Complex Inorganic Oxides to Ag–Bi Nanoalloy: Synthesis by Femtosecond Laser Irradiation 

      Machado, Thales Rafael; Guerra Macedo, Nadia; Assis, Marcelo de; Doñate-Buendía, Carlos; Mínguez-Vega, Gladys; Teixeira, Mayara Mondego; Foggi, Camila Cristina; Vergani, Carlos; Beltrán Mir, Héctor; Andres, Juan; Cordoncillo, Eloisa; Longo, Elson American Chemical Society (2018-08-24)
      Bimetallic nanoalloys with a wide variety of structures and compositions have been fabricated through many diverse techniques. Generally, various steps and chemicals are involved in their fabrication. In this study, the ...

    • openAccess   Morphology Diversity of L‐Phenylalanine‐Based Short Peptide Supramolecular Aggregates and Hydrogels 

      Martí-Centelles, Rosa; Escuder, Beatriu Wiley (2018-08)
      Supramolecular aggregates and hydrogels of diverse morphologies can be obtained by replacing the widely studied aromatic N‐capping of phenylalanine derivatives by long alkyl chains. Simple changes in chain length and number ...

    • closedAccess   Self-Assembling of Er2O3–TiO2 Mixed Oxide Nanoplatelets by a Template-Free Solvothermal Route 

      Julian-Lopez, Beatriz; Martos Macián, Mónica; Ulldemolins, Natalia; Odriozola, José A.; Cordoncillo, Eloisa; Escribano López, Purificación Wiley (2009)
      An easy solvothermal route has been developed to synthesize the first mesoporous Er2O3–TiO2 mixed oxide spherical particles composed of crystalline nanoplatelets, with high surface area and narrow pore size distribution. ...

    • closedAccess   Tuning Chelation by the Surfactant-Like Peptide A(6)H Using Predetermined pH 

      Castelletto, Valeria; Hamley, Ian W.; Segarra Maset, María Dolores; Berdugo Gumbau, Cristina; Miravet, Juan; Escuder, Beatriu; Seitsonen, J.; Ruokolainen, J. American Chemical Society (2014)
      We examine the self-assembly of a peptide A6H comprising a hexa-alanine sequence A6 with a histidine (H) “head group”, which chelates Zn2+ cations. We study the self-assembly of A6H and binding of Zn2+ ions in ZnCl2 ...
