    Síntesi i caracterització d'aliatges amb memòria magnètica de forma 

    Coll Riera, Rosa (Date of defense: 2014-11-13)

    Els aliatges magnètics amb memòria de forma es caracteritzen per presentar tant la transformació estructural austenita – martensita com la magnètica (ferromagnetisme – paramagnetisme). El conjunt de propietats els fa ...

    Sunshine duration as a proxy of the atmospheric aerosol content 

    Sanchez Romero, Alejandro (Date of defense: 2016-06-06)

    One of the most important radiative properties of aerosols is their optical thickness (AOD), which is closely linked to the total burden of atmospheric aerosols. On the contrary, we do avail of long time series of sunshine ...

    Synthèse, caractérisation et application des alliages à base de Mn-X-Y (X=Al; Y=Fe,Co) et Ca-Al dans la dégradation d'un colorant azoïque "Black 5" utilisé dans l'industrie de textile 

    Ben Mbarek, Wael (Date of defense: 2018-11-20)

    This work is framed in the general context of the synthesis and characterization of Mn or Ca based alloys, which are subsequently applied in degradation processes of azo dyes used in the textile industries. The alloys were ...

    Synthèse, caractérisation et étude magnétique des alliages à mémoire de forme de type Heusler Ni-Mn-Sn-X (X= Pd, Cu) 

    Wederni, Asma (Date of defense: 2021-11-26)

    Shape memory alloys witch exhibit magnetically induced phase transformations at room temperatures are the most interesting for magnetic cooling applications. Heusler type alloys (both stoichiometric and non-stoichiometric) ...

    Waves and turbulence on submerged and emergent aquatic vegetation 

    Pujol Company, M. Dolors (Date of defense: 2013-04-16)

    Coastal zones are governed by physical forces originating from tidal currents, waves, winds and night convection, amongst others, and are characterized by the presence of canopy meadows. This thesis studies the hydrodynamic ...

    X-ray tomography investigation of the impact damage mechanisms of thin-ply composites and the use of veils to improve their impact tolerance 

    García Rodríguez, Santiago (Date of defense: 2019-06-28)

    This thesis investigates the impact response of novel laminates made with “thin-plies” as well as proposes a toughening method to improve their impact tolerance. To this purpose, we devised a wide experimental campaign ...
