    Posibles nuevas vías de investigación en teoría de la comunicación a través de modelos matemáticos: análisis topológico
    (Centro de Investigaciones Sociológicas, 1978) Corres Sanz, Jesús María; Burillo López, Pedro; Automática y Computación; Automatika eta Konputazioa
    Uno de los pocos puntos en los que los metodólogos de las ciencias sociales están de acuerdo es el divorcio existente entre trabajo teórico y trabajo metodológico en las prácticas sociales concretas. Por otro lado, para la creación del corpus de las ciencias sociales se ha tropezado secularmente con un grave problema o inconveniente: la carencia o insuficiencia de un «lenguaje común» que permitiera el trabajo interdisciplinario de los diferentes científicos sociales. Por paradójico que parezca, este inconveniente no está siendo solucionado, únicamente, desde dentro de las ciencias sociales, sino que ha sido precisa la colaboración de otras ciencias, especialmente las ciencias exactas (física, matemáticas...). Estos dos aspectos epistemológicos de las ciencias sociales han inducido a buena parte de los investigadores sociales a abordar el estudio y análisis de las prácticas sociales a través de la Teoría de la Comunicación.

    Nanofilms on a hollow core fiber
    (SPIE, 2006) Matías Maestro, Ignacio; Bravo Larrea, Javier; Arregui San Martín, Francisco Javier; Corres Sanz, Jesús María; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa; Gobierno de Navarra / Nafarroako Gobernua
    We experimentally study the behavior of one multimode fiber–hollow core fiber–multimode fiber structure when nanofilms are deposited on it with the aim of developing practical evanescent field-based devices, such as sensors, filters, etc. The electrostatic self-assembly (ESA) method is used as the deposition technique and the chosen polymers are PDDA and Poly R-478 because of their well-known optical properties and their potential application as humidity sensors. Three different types of hollow core, fibers are used for the fabrication of the devices and at two different wavelengths. An oscillatory-decreasing transmitted optical power is obtained as the thickness of the nanofilms is increased.

    Study and optimization of self-assembled polymeric multilayer structures with neutral red for pH sensing applications
    (Hindawi / Wiley, 2008) Goicoechea Fernández, Javier; Arregui San Martín, Francisco Javier; Corres Sanz, Jesús María; Matías Maestro, Ignacio; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    The characterization of nanostructured thin films is critical in the design and fabrication of optical sensors. Particularly, this work is a detailed study of the properties of layer-by-layer electrostatic self-assembled multilayer (LbL) structures fabricated using poly(allylamine hydrochloride) (PAH) and Neutral Red (NR) as cations, and poly(acrylic acid) (PAA) as polyanion. These LbL films, due to the colorimetric properties of the NR, are suitable for sensor applications such as pH sensing in the physiological range. In the (PAH+NR/PAA) LbL structure, it has been observed a very important influence of the pH of the solutions in the properties of the resultant films. Different techniques such as spectroscopy and atomic force microscopy (AFM) are combined to characterize the films, and the results are analyzed showing coherence with previous works. The LbL structure is finally optimized and dramatically improved nanostructured films were fabricated, showing good sensing properties, short response times, and good stability.

    Spectral evolution with incremental nanocoating of long period fiber gratings
    (Optical Society of America, 2006) Del Villar, Ignacio; Corres Sanz, Jesús María; Achaerandio Alvira, Miguel; Arregui San Martín, Francisco Javier; Matías Maestro, Ignacio; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    The incremental deposition of a thin overlay on the cladding of a long-period fiber grating (LPFG) induces important resonance wavelength shifts in the transmission spectrum. The phenomenon is proved theoretically with a vectorial method based on hybrid modes and coupled mode theory, and experimentally with electrostatic self-assembly monolayer process. The phenomenon is repeated periodically for specific overlay thickness values with the particularity that the shape of the resonance wavelength shift depends on the thickness of the overlay. The main applications are the design of wide optical filters and multiparameter sensing devices.
