Fernández, A. ; Montero, Javier ; Tordesillas, J. ; Amo, Ana del ; Biging, G. | Universidade de Vigo | 2000Información del artículo Análisis comparativo de un modelo no supervisado de clasificación difusa frente al modelo clásico.texto impreso
Fernández, A. ; Quintero, J. ; Hornero, J. ; Zuluaga Arias, Pilar ; Navas, M. ; Gómez, C. ; Escudero, J. ; García Campos, N. ; Biederman, J. ; Ortiz, T. | Elsevier | 2009-04Background: Attention-deficit/hyperactivity disorder (ADHD) is defined as the most common neurobehavioral disorder of childhood, but an objective diagnostic test is not available yet to date. Neurophychological, neuroimaging, and neurophysiologi[...]texto impreso

Guerrero, E. ; Rojas, T. C ; Multigner, M. ; Crespo del Arco, Patricia ; Muñoz Márquez, M. A. ; García, M. A. ; Hernando Grande, Antonio ; Fernández, A. | Pergamon-Elsevier Science Ltd | 2007-03In the present paper, we show an exhaustive microstructural characterization of thiol-capped gold nanoparticles (NPs) with two different average particle sizes. These samples are compared with the polymer-like Au(I) phase formed as a precursor d[...]texto impreso
Sampedro, B. ; Crespo del Arco, Patricia ; Hernando Grande, Antonio ; Litran, R. ; Sánchez López, J. C. ; López Cartes, C. ; Fernández, A. ; Ramírez, J. ; Gónzalez Calbet, J. ; Vallet, M. | American Physical Society | 2003-12-05The onset of ferromagnetism has been experimentally observed in small Pd particles of average diameter 2.4 nm. High-resolution studies reveal that a high percentage of the fcc particle exhibits single and multiple twinning boundaries. The sponta[...]texto impreso
Hernando Grande, Antonio ; Crespo del Arco, Patricia ; García, M. A. ; Fernandez Pinel, E. ; De la Venta,1, J ; Fernández, A. ; Penadés, S. | American Physical Society | 2006-08It has been observed for palladium and gold nanoparticles that the magnetic moment at a constant applied field does not change with temperature over the range comprised between 5 and 300 K. These samples, with sizes smaller than 2.5 nm, exhibit [...]texto impreso
Fernández, A. ; Rodríguez-Palancas, A. ; López-Ibor, M. ; Zuluaga Arias, Pilar ; Turrero, Agustín ; Maestú, F. ; Amo, C. ; López-Ibor, Jr., J.J. ; Ortiz, T. | Canadian Medical Association | 2005-01Objective: To test the hypothesis that there is increased low-frequency activity located predominantly in the frontal lobe in patients with major depressive disorder using magnetoencephalography. Methods: We carried out an unmatched or separate [...]texto impreso
Fernández, A. ; López-Ibor, M.I. ; Turrero, Agustín ; Santos, J. M. ; Morón, M.D. ; Hornero, R. ; Gómez, C. ; Méndez, M.A. ; Ortiz, T. ; López-Ibor, J.J. | Elsevier | 2011-11Objective: The neurodevelopmental-neurodegenerative debate is a basic issue in the field of the neuropathological basis of schizophrenia (SCH). Neurophysiological techniques have been scarcely involved in such debate, but nonlinear analysis meth[...]texto impreso
Litran, R. ; Sampedro, B. ; Rojas,, T. C. ; Multigner, M. ; Sánchez López, J. C. ; Crespo del Arco, Patricia ; López Cartes, C. ; García, M. A. ; Hernando Grande, Antonio ; Fernández, A. | American Physical Society | 2006-02Palladium nanoparticles capped with different protective systems in a size range between 1.2 and 2.4 nm have been obtained by varying the preparation chemical method. Magnetization curves for all the samples show hysteresis loops, evidencing a f[...]texto impreso
Guerrero, E. ; Munoz-Marquez, M. A. ; Fernández, A. ; Crespo del Arco, Patricia ; Hernando, A. ; Lucena, R. ; Conesa, J. C. | American Institute of Physics | 2010-03-15In the last years, the number of studies performed by wholly independent research groups that confirm the permanent magnetism, first observed in our research lab, for thiol-capped Au nanoparticles (NPs) has rapidly increased. Throughout the year[...]texto impreso

A. ; Hernando Grande, Antonio ; Penadés, S. ; Fernández, A. | American Physical Society | 2004-08-20We report on the experimental observation of magnetic hysteresis up to room temperature in thiol-capped Au nanoparticles with 1.4 nm size. The coercive field ranges from 860 Oe at 5 K to 250 Oe at 300 K. It is estimated that the Au atoms exhibit[...]texto impreso

A. ; Crespo del Arco, Patricia ; Fernandez Pinel, E. ; Hernando Grande, Antonio ; Fernández, A. | IOP publishing ltd | 2008-04-30Surface plasmon resonance measurements and magnetic characterization studies have been carried out for two types of thiol-capped gold nanoparticles (NPs) with similar diameters between 2.0 and 2.5 nm and different organic molecules linked to the[...]texto impreso
García, M. A. ; De la Venta, J ; Crespo del Arco, Patricia ; LLopis,, J. ; Penadés, S. ; Fernández, A. ; Hernando Grande, Antonio | American Physical Society | 2005-12In this Rapid Communication we show the relationship between surface plasmon resonance damping and the intensity of surface bonding for capped Au nanoparticles, (NPs). Up to now the influence of capping has been included as a phenomenological mo[...]
