Caracterización magnética de un cordón de soldadura
(Congreso Internacional de Metalurgia y Materiales SAM-CONAMET 2018, 2018-10-30)Cuando un material ferromagnético es sometido a campos magnéticos lentamente variables, se generan cambios en su magnetización, produciéndose “saltos” discretos. Estos saltos se generan por el movimiento de las paredes de ... -
Nanorod-based plasmonic substrates with predefined optical resonances
(2018)To design and fabricate plasmonic substrates to be used in ultrasensitive chemical sensing or surfaceenhanced spectroscopies, it is important to achieve control on the morphology, dimensions and surface density of metallic ... -
Fabricación y Caracterización de Sustratos Plasmónicos Basados en Nanobastones de Oro
(2015)Se fabricaron sustratos plasmónicos mediante el recubrimiento controlado de superficies de vidrio y películas delgadas de oro con nanobastones de oro. Estos sustratos nanoestructurados poseen resonancias ópticas en el ... -
Monitoring the Photothermal Reshaping of Individual Plasmonic Nanorods with Coherent Mechanical Oscillations
(2018-12-03)Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resolved ... -
Plasmon-induced photochemical synthesis of silver triangular prisms and pentagonal bipyramids by illumination with light emitting diodes
(2013)We have grown silver prisms and pentagonal bipyramids, induced by plasmon excitation on a colloidal solution under the irradiation of light emitting diodes of different colors. Two methods of synthesis of the seeds were ... -
Harmonic demodulation and minimum enhancement factors in field-enhanced near-field optical microscopy
(2015-01)Field enhanced scanning optical microscopy (FESOM) relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing ... -
Recubrimiento controlado de sustratos de vidrio con nanobastones metálicos
(2015-03-12)Se realizó la síntesis de nanobastones de oro monodispersos con una eficiencia superior al 80% sobre el total de nanopartículas, caracterizado por una resonancia plasmónica longitudinal cercana a los 800 nm. Se modi- ficaron ... -
Nanoestructuras esféricas núcleo-cáscara con resonancias plasmónicas sintonizables
(Asociación Argentina de Investigación en Fisicoquímica, 2019-04)Las nanopartículas constituidas por un núcleo dieléctrico rodeado por una capa metálica forman una clase de nanoestructuras con notables propiedades ópticas. Sus resonancias de plasmones superficiales derivan del acoplamiento ... -
Four-layer spherical self-organized maps neural networks trained by recirculation to follow the phase evolution of a nearly four-year rainfall signal.
(2019-01)This work is intended to organize a big set of time series of rainfall reanalysis built on the Fourier harmonic that corresponds to the 4.8year cycle of variability. To do that a self-organized map is implemented in four ... -
Four-layer spherical self-organized maps neural networks trained by recirculation to simulate perception and abstraction activity : application to patterns of rainfall global reanalysis
(2018-07)Abstract This work is intended to organize a big set of time series. To do that a self-organized map is implemented in four spherical layers trainded by recirculation. This way tries to simulate aspects of perceotion and ...
