Advanced Transition Metal Oxide Nanomaterials for Energy Technologies
[eng] Transition metal oxides (TMOs) are compounds formed from transition metals and oxygen, known for their complex and versatile structures, including diverse crystal forms and multiple oxidation states. This versatility ...
Few Interacting Particles in Low-Dimensional Quantum Systems: From Harmonic Oscillators to Fractal Lattices
[eng] Quantum mechanics is a fascinating field to explore, where its effects are usually non- trivial and counterintuitive. In this Thesis, we focus on systems with a small number of particles in low dimensions, where the ...
Enhanced Optical Response in Arrays of Multifunctional Plasmonic Nanostructures
[eng] This thesis is devoted to the study of two plasmonic nanostructures that present a 3-fold symmetry, namely, inverted honeycomb lattices of bars and twisted stacks of triskelion nanostructures. These systems are ...
Directed cell migration: forces, shapes, and fluctuations in tissues. From active hydrodynamics to experiments
[eng] This thesis investigates collective cell migration in epithelial tissues, under the framework of active soft matter physics. We model epithelial tissues as active polar fluids, since their components, the cells, have ...
Development of a Neurovascular Microfluidic Model with an Endothelial Barrier-Integrity Sensor for Pharmaceutical Innovation in Neurodegenerative Diseases
[eng] Neurodegenerative diseases represent a significant health challenge, as no cure is currently available. The unique anatomy of the blood-brain barrier, which limits drug delivery to the brain, as well as the lack of ...
High Entropy Materials as Air Cathodes for Robust Zinc-Air Batteries
[eng] This thesis focuses on the development of high-entropy materials (HEMs) as advanced bifunctional catalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). The study systematically investigates ...
A multidisciplinary approach to rheological blood characterisation and angiogenesis modelling using microfluidics
[eng] Blood viscosity plays a critical role in cardiovascular health, influencing hemodynamic processes and disease states. Accurate and rapid measurement of blood rheological properties is essential for diagnostic and ...
Effective field theory methods at high temperature and chemical potential
[eng] This thesis applies and develops effective field theory methods for the study of plasmas at high temperature and/or density. In the 90s, the theoretical frameworks necessary to study quantum electrodynamics (QED) and ...
Salt dependent DNA translocation dynamics across nanopores
[eng] This thesis uses two complementary single-molecule techniques, nanopipette microscopy and optical tweezers, to investigate the impact of various monovalent salts at high concentrations in DNA. The thesis begins by ...
New experimental techniques for axion searches in the RADES and BabyIAXO experiments
[eng] Initially proposed as part of the solution to the strong CP problem of the Standard Model of particle physics, axions and axion-like particles appear on several Beyond Standard Model extensions. These pseudoscalar ...
Dissipation in active matter systems: self-organization and transport
[eng] This thesis delves into the study of catalytic Janus particles (AP) that convert chemical energy into mechanical motion, resulting in energy dissipation. Understanding this dissipation is challenging due to the ...
A Comprehensive Validation of Global Precipitation Measurement Satellite Products Over a Western Mediterranean Region
[eng] Precipitation estimation is essential for understanding atmospheric processes, water resource management, and climate modeling. Advances in remote sensing, particularly the Global Precipitation Measurement (GPM) ...
Optimization and degradation of supercapacitors in aqueous and super-concentrated “water-in-salt” electrolytes
[eng] Supercapacitors are electrochemical energy storage devices. Its energy comes from the electrostatic accumulation of ionic charge on the surface of an electrode, compensated by an opposite electrical charge on the ...
Nanocrystals boost electrochemical oxidation of biomass-derived compounds
[eng] The global energy situation coupled with the indiscriminate use of fossil fuels is currently a major problem for both human health and the prosperity of the planet. Biomass represents a highly promising renewable ...
Orígens del concepte d’indistingibilitat quàntica en l’estadística de Fermi-Dirac
[cat] Entre el 1924 i el 1927 a través de la mecànica quàntica va començar a entreveure’s la idea de que alguns sistemes estaven formats pel que avui dia anomenem “partícules indistingibles”. Aquesta nova percepció de la ...
The Onset of Geometry in Complex Networks - From Stuctural Properties to Dynamical Processes
[eng] Over the past few decades, the use of complex networks to describe the properties of systems of many interacting particles has become widespread in many fields of science. Surprisingly, networks from disparate ...
Overcoming antiapoptotic adaptations to enhance non-small cell lung cancer treatment
[eng] The treatment of lung cancer has substantially progressed due to the development of targeted therapies against driver oncogenes. However, this type of cancer is still the leading cause of cancer-related mortality, ...
Direct CP measurement of Lambda b0->pkGamma decay and photon reconstruction optimization for Run III conditions
[eng] This thesis focuses on conducting a CP measurement of the rare radiative b-baryon decay Lambda b0 -> pkgamma using proton-proton collisions collected by the LHCb experiment during both the entire Run I and Run II ...
Developing a 3D full-thickness skin model based on thiol-norbornene chemistry
[eng] Collagen-based gels are widely used as the standard for in vitro skin tissue models due to their biocompatibility and structural similarity to natural skin. However, they have notable drawbacks, such as batch-to-batch ...
Synthesis of value-added Nitrogen-based products through advanced electrocatalytic systems
[eng] The transition towards a sustainable and carbon-neutral economy is crucial due to the escalating concerns over excessive greenhouse gas emissions, climate change, and the need for effective utilization of renewable ...
