In this thesis, single-molecule experiments using LOT are employed to extract accurate information about the thermodynamics and kinetics of various molecular systems, with special emphasis on the elastic properties of ...
[eng] This thesis focuses on RNA, one of the most versatile molecules in biological systems, and how intermolecular interactions with ions and proteins govern RNA folding. On its way to biological function, RNA transits a ...
In this thesis, it is detailed the bottom-up production and characterization of thermoelectric (TE) nanomaterials with significant enhanced performance by using colloidal nanocrystals (NCs) as building blocks. The production ...
Recently lepton flavor universality tests in colliders have reported tensions with the Standard Model, providing an experimental hint at low energies of the effect of a new high energy theory. These tensions are known as ...
[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 ...
[eng] Materials and thin film photovoltaic (TFPV) devices exhibit a high level of complexity, characterized by their multi scale, multi layer, and multi element structures, along with complex manufacturing processes. ...
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 ...
