    Rational chemical design of Triarylmethyl-based devices and 2D materials 

    Alcón Rovira, Isaac (Date of defense: 2018-03-14)

    In this PhD thesis I have studied through state-of-the-art quantum simulations (mainly within the density functional theory approach, DFT) triarylmethyl (TAM) based systems with potential for future nano-devices and designed ...

    Rationalization of the Mechanism of Bistability in Dithiazolyl-based Molecular Magnets 

    Francese, Tommaso (Date of defense: 2019-03-25)

    In this work, we characterized and studied the properties associated to DTA-based bistable organic molecular magnetic systems, namely PDTA and TDPDTA, respectively. In both cases, the low and high temperature phases have ...

    Recubrimientos micro-nano estructurados de grandes espesores por proyección fría para la reparación y protección de componentes industriales de altro valor añadido 

    Bedoya Escobar, Juliana (Date of defense: 2017-07-12)

    La proyección fría es una técnica de proyección térmica que permite la obtención de recubrimientos metálicos y metal/cerámicos con estructuras densas (porosidad inferior a 0,1%) y libres de óxidos. De manera general, ésta ...

    Strategies to synthesize carbon-supported elctrocatalysts with reduced Pt content and increased activity for use in low temperature fuel cells 

    Garcia Cardona, Júlia (Date of defense: 2023-12-04)

    [eng] Conventional catalysts for polymer electrolyte fuel cells are based on Pt supported on porous carbons, generally carbon blacks. However, Pt is expensive and scarce and is poisoned by CO, which is present in the ...

    Structural organization of model membranes: a complementary approach combining atomic force microscopy and X-ray techniques 

    Gumí Audenis, Berta (Date of defense: 2018-04-27)

    Biological membranes (BMs) are self-sealing boundaries, which confine the permeability barriers of cells and organelles and provide the means to compartmentalize functions. Apart from being crucial for the cell structure, ...

    Study of solid particle materials as high temperature Thermal Energy Storage and Heat Transfer Fluid for Concentrating Solar Power 

    Calderón Díaz, Alejandro (Date of defense: 2019-10-24)

    Renewable energies have a major role in today’s energy systems development, energy security and climate change fight. Thermal Concentrating Solar Power (CSP) has the potential to get up to 11.3% of world’s electricity ...

    Theoretical reaction and relaxation dynamics in superfluid helium nanodroplets 

    Blancafort Jorquera, Miquel (Date of defense: 2019-11-15)

    The study of superfluid helium has been carried out mainly by physicists. In recent years, taking advantage of the potentialities presented by superfluid helium nanodroplets (HeNDs) as inert matrices at very low temperatures ...

    Theoretical study of excited states in molecules and molecular aggregates relevant for optoelectronic applications 

    Climent Biescas, Claudia (Date of defense: 2017-07-07)

    In this thesis, different organic and organometallic molecules with interest for optoelectronic applications have been studied from a computational standpoint. The work presented in this thesis belongs to the molecular ...

    Transport and assembly of colloids in liquid crystals 

    Pagès Casas, Josep M. (Date of defense: 2019-07-19)

    Particles dispersed in nematic liquid crystals (NLCs), also called nematic colloids, are nowadays typical experimental systems studied in the field of Soft Matter. In this scenario, the interactions and forces between ...
