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 ...
Design, Development, and Validation of Medical Wearable Devices: Challenges and Solutions for Technology Integration, Industrialization and Certification
[eng] Due to the advances in the field of medical care, worldwide life span has increased over the past decades. This rise in longevity comes hand in hand with an increase in health expenditure as aging-associated diseases ...
GHz Magnetization Dynamics in X-ray PhotoEmission Electron Microscopy (XPEEM)
[eng] This thesis presents the recent results achieved during my Ph.D. This is a research project in the field of condensed matter physics, under the supervision of Dr. Michael Foerster of the ALBA Synchrotron and Dr. ...
Development of advanced nuclear magnetic resonance methods for biochemical analysis of biofluids and hyperpolarized magnetic resonance spectroscopic imaging for organ-on-chip
[eng] The main challenge in modern medicine is to prevent diseases and, when disease strikes, to detect it and cure it efficiently, promptly and cost-effectively (understanding cost as economic burden, patient and relatives ...
On the use of multilayer hexagonal boron nitride as dielectric in micro/nano-electronic devices
[eng] Electronic devices are becoming increasingly essential for our work and life. The downscaling process of electronic devices, as well as the development of new devices for artificial intelligence and internet of ...
Design of SiPM Front-End Readout Integrated Circuits for Large Area Single-Photon Imagers
[eng] The demand for particle detectors with superior timing performance and precise energy measurement has significantly increased in recent years. Applications requiring extensive detection areas, such as Time-of-Flight ...
Brane-Worlds and Higher Derivative Gravities
[eng] This thesis explores and combines, through the lens of the holographic correspondence, two relevant topics in the field of gravitational high-energy theory: higher-derivative theories of gravity and brane-world ...
Exploring Three-State Opinion Dynamics: A Journey Through Single and Multilayer Network Topologies
[eng] The word "emergence" refers to the formation of collective behaviors, actions not undertaken by the components of a system when isolated. On one hand, we have the components—particles or agents, ranging from water ...
Rheological Characterization of Healthy and non-Healthy Blood using Electronic Detection of the Fluid Front
[eng] In this research, we developed a technique and experimental setup that is the basis of a device, for the characterization of blood rheology and its connection to the rigidity of red blood cell (RBC). Our experimental ...
Structural Engineering of Advanced Cathode Materials for Aqueous Zinc-ion Batteries
[eng] Aqueous zinc ion batteries (AZIBs) have garnered significant research attention due to their remarkably high-volume energy density, reaching up to 5,851 mAh mL-1. This surpasses the capabilities of state-of-the-art ...
Quantum Algorithms: bridging the gap between theory and experiment
[eng] As more sophisticated quantum devices are being developed, the scope of what can successfully be executed on them grows. In this period, an essential piece of this process is the hand-in-hand collaboration between ...
