[eng] This thesis develops, validates, and explores applications of the Franzese-Stanley (FS) coarse-grained model for bulk water, ultimately intended to represent the solvent in large-scale simulations of biological ...
In the present thesis, single-molecule experiments have been carried out using optical tweezers with a temperature controller. Employing equilibrium and non-equilibrium experiments, the free energy, enthalpy, and entropy ...
The transformation of the current energy model towards a more sustainable mix, independent of fossil fuels, requires the exploration of new technologies that are capable of taking advantage of excess electricity derived ...
Injuries and conditions of musculoskeletal tissues are among the main causes of disability worldwide and there is a wide need for improved regenerative therapies. In vitro platforms and biomaterials that aim to guide stem ...
Dielectrics are insulating materials used in many different electronic devices (e.g. capacitors, transistors, barristors), and play an important role in all of them. In fact, the dielectric is probably the most critical ...
In order to mitigate the climate change effects, the world is undergoing an energy transition from polluting sources towards renewable energies. This transition is turning the electricity system more dependent on atmospheric ...
Cobalt-based nanomaterials are an important class of electrocatalysts that own abundant and diverse d-orbital electronic structures, and can exhibit excellent HER, OER, EOR catalytic activity and stability in energy ...
[eng] Quantum annealing is a heuristic analog quantum algorithm that promises potential quantum speedup over classical algorithms for a huge variety of optimization problems. Current existing annealers, despite their ...
Metal phosphides are an important class of functional materials that exhibit a wide range of applications for energy storage and conversion. However, the synthesis of metal phosphide nanoparticles and its scalability is ...
The main goal of this thesis has been to apply in-situ Transmission Electron Microscopy (TEM) electrical measurements using a Scanning Tunneling Microscopy (STM) tip, combined with TEM imaging and spectroscopic techniques, ...
Most systems in Nature manifest complex transport phenomena arising from the interplay of multiple time and length scales, be them intrinsic in the system’s dynamics or externally enforced. It is the case, for instance, ...
The direct manipulation of spin currents with no charges involved along with the delicate interplay between charge, spin and orbital degrees of freedom in materials and structures has attracted a renewed interest in the ...
Els treballs realitzats en aquesta tesi doctoral s’han dirigit cap al desenvolupament, optimització i regeneració dels sensors d’oxigen per a la detecció d’humitat en entorns d’alta temperatura per acomplir amb un objectiu ...
Dentro del gran desarrollo que en nuestros dias tienen los dispositivos electrónicos de estado sólido, el contacto metal –semiconductor diodo Schottky ha encontrado recientemente un interés renovado. Diversos progresos ...
A partir de los cálculos de la atenuación de la radiación solar directa a incidencia normal en ciertos intervalos espectrales y utilizando como instrumentos de medida un actinómetro Linke-Feussner y varios heliofotómetros ...
Los métodos de cálculo y corrección de sistemas ópticos sufrieron una total revolución hacia 1950 con la aparición de las calculadoras electrónicas programables. Su rapidez y potencia de cálculo permiten abordar los ...
Cosmology is the science that studies the Universe as whole, aiming to understand its origin, composition and evolution. During the last decades, cosmology has transitioned from a “data staved” to a “data driven” science, ...
[eng] The overwhelming evidence for the existence of dark matter in the Universe, and the discovery of the neutrino masses, are striking indicators of the need for new physics beyond the ΛCDM and Standard Model paradigms. ...
One of the most serious challenges facing society is the need to reduce the emissions of greenhouse gases such as carbon dioxide (CO2), mainly caused by the widespread use of fossil fuels. The energy transition to renewable ...
[eng] Climate variations at annual to decadal time scales affect many regions around the globe, causing direct impacts on the economy, ecosystems and society. Knowing these variations in advance allows for implementing ...
