  • AFM as an alternative for Young's modulus determination in ceramic materials at elastic deformation regime 

    Roa Rovira, Joan Josep; Oncins, Gerard; Dias, F. T.; Vieira, V. N.; Schaf, J.; Segarra, M. (2011-09-08)
    Restricted access - publisher's policy
    A novel alternative to the conventional nanoindentation technique for hard materials is presented. An atomic force microscopy probe is used as an indenter, applying loads in the nN range and producing elastic deformations ...
  • Caracterización mecánica a escala picométrica de YBa1.75Sr0.25Cu3O7-d monocristalino mediante la técnica de autoflujo 

    Roa Rovira, Joan Josep; Dias, F.T.; Vieira, V.N.; Oncins, Gerard; Díaz, Jordi; Schaf, J.; Capdevila, X.G.; Segarra, M. (Universidad de Cantabria, 2009)

    Se implementa un método para indentar superficies rígidas a niveles nanométricos utilizando un microscopio de fuerzas atómicas (Atomic Force Microscopy-AFM), empleando el modo de espectroscopia de fuerzas (Force ...
  • Incorporation of ubiquinone in supported lipid bilayers on ITO 

    Hoyo Pérez, Javier; Guaus Guerrero, Ester; Oncins, Gerard; Torrent Burgués, Juan; Sanz Carrasco, Fausto (2013-05-31)
    Restricted access - publisher's policy
    Ubiquinone (UQ) is one of the main electron and proton shuttle molecules in biological systems, and dipalmitoylphosphatidylcholine (DPPC) is one of the most used model lipids. Supported planar bilayers (SPBs) are extensively ...
  • Journal of Materials Chemistry C 

    El-Hachemi, Zoubir; Escudero, Carlos; Acosta-Reyes, Francisco; Casas Becerra, María Teresa; Aloni, Shaul; Oncins, Gerard; Sorrenti, Alessandro; Crusats, Joaquim; Ribó Trujillo, Josep M.; Campos López, Josefina de Lourdes (Royal Society of Chemistry, 2013-03-28)
    Open Access
    The structure of the meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) J-aggregates could be determined by X-ray and electron diffraction methods. A sheet-like architecture reveals the relationship between structure and ...
