Engineering metastructures for the full control of flexural waves
Thin plate structures are widely used in dynamic platforms. The artificial modulation of elastic waves in thin plates has always been one of the most important factors affecting the dynamic performance of devices. Dynamic ...
Modulated Techniques to Analyse Photoconversion Devices
The urgent need for a sustainable energetic system to mitigate global warming has increased interest in solar energy as a promising solution. Currently, photoconversion technologies generate only a small fraction of the ...
Hysteresis Control in Hybrid Perovskite-based Devices for Photovoltaic and Neuromorphic Computing Applications
Perovskite solar cells have been rapidly advancing in record efficiencies at an unprecedented rate already approaching the theoretical maximum efficiency in just over a decade of development. Most notably, perovskites ...
Development and Characterization of Electro- and Photo-Electrochemical Systems for High-Added-Value Products
The main challenge in the development of electrochemical and photoelectrochemical systems is the kinetics of the anodic oxygen evolution half-reaction (OER), which is intrinsically slow. For this reason, in this thesis all ...
Development of Advanced Materials Based on Polymeric Ionic Liquids Formulated for Additive Manufacturing
This thesis focuses on the design, development and characterisation of 3D printable materials based on polymeric ionic liquids. Additive manufacturing, commonly known as 3D printing, is a revolutionary set of technologies ...
Determinación de distribuciones de fase mediante luz estructurada y detecció integrada
La observación fue la primera herramienta del hombre para entender su entorno y comprender los fenómenos naturales que se presentaban a lo largo del tiempo. Algunas de las explicaciones a dichos fenómenos se pueden percibir ...
Development of perovskite optoelectronic devices on flexible substrates
In this thesis, first, the monolithic integration of a perovskite-based optical waveguide amplifier together with a photodetector on a nanocellulose substrate is shown to demonstrate the feasibility of a stretchable signal ...
Degradation of perineuronal nets in the cerebellum to prevent relapse of drug seeking
Drug addiction can be associated with the ability of certain substances to hijack natural learning and memory mechanisms. This thesis focuses on the study and manipulation of cerebellar perineuronal nets (PNNs) following ...
Small Perturbation Techniques for the Electronic Analysis of Perovskite Devices
Metal-halide perovskites have emerged as a promising semiconductor material for a variety of potential applications, due to their intrinsic properties and their low-cost fabrication methods. Perovskite solar cells have ...
Design of catalytic systems for sustainable processes development: hydrogen storage and biomass transformation
The present PhD. Thesis is the result of research efforts directed towards the design and development of more sustainable catalytic processes trying to address some of the current challenges that today our society is facing ...
Moment Spectrum and First Dirichlet Eigenvalue of Geodesic Balls in Riemannian Manifolds
In this work, given a geodesic ball of a Riemannian manifold with radius less than the injectivity radius of its center, we prove our estimates for some geometric invariants defined on the ball. The invariants that we will ...
Electrophysiological characterization of membrane permeability: from protein channels to nanoparticles
Cell membrane permeability is modulated by complex dynamical structures created by objects interacting with the lipid bilayer. Paying attention to the kinetics of ion transport in response to different bioelectrochemical ...
High Quality Perovskite Materials for X-Ray Detection: Effect of Mobile Ions on Dark Current Stability
Long-term stability of perovskite-based X ray detectors under working condition remains as the bottle-neck for technological purpose. Several effects are attributed to the presence of mobile ions in these materials such ...
