In this project, nanoparticles were produced by solution-based one-pot synthesis, particularly colloidal methods. A series of powerful tools were used to characterize the structure and surface compositions before they were ...
In this thesis, we employ noise-correlation force spectroscopy measurements using LOT to extract valuable information about the passive and active fluctuations of DNA molecules and red blood cells. We have chosen the laser ...
[eng] A set of disordered interacting building blocks may form ordered structures via self-assembly. External intervention in the system through the addition of chemical species or the application of forces leads to different ...
In this thesis we have employed the holographic duality to study the non-perturbative regime of a one-parameter family of theories with multi-scale dynamics. Normally, this (super)string theory motivated duality identifies ...
Anaerobic digestion is a worldwide technology to treat organic waste streams, primarily due to its capacity to produce methane as renewable energy. However, there is an increasing interest on nutrient recovery (N and P), ...
La contribución principal de esta tesis consiste en el diseño, implementación y verificación, mediante el uso de herramientas digitales, de una red de distribución de reloj para FastICpix, un detector píxel híbrido capaz ...
[eng] The total amount of global information to be stored and computed is increasing exponentially since the beginning of the 21st century. The semiconductor industry made great efforts to push the silicon-based integrated ...
Time-of-Flight Positron Emission Tomography (TOF-PET) scanners demand fast and efficient photo-sensors and scintillators coupled to fast readout electronics. Nowadays, there are two main configurations regarding the ...
Clinical treatments based on electrical stimulation of excitable cells have been efficacious for a variety of diseases. However, these devices are often limited by their bulkiness, need for wiring electrodes and inability ...
This thesis presents the development of different self-powered devices that allow the conductivity measurement of liquid samples, from different types of water samples to biological fluids. The devices have been developed ...
Our modern society is becoming increasingly dependent on the constant stream of information sent out by satellites orbiting Earth. However, highly energetic rays traversing the near-Earth space environment pose a constant ...
[eng] Prostate cancer is one of the most frequently encountered malignancies, with 1.4 million new cases in the past year, marking the second leading cause of deaths in men worldwide. Although it is known to be treatable ...
Our understanding of the Universe has advanced tremendously in the past few decades, with General Relativity(GR) laying the ground for a successful model for the Universe, ΛCDM. However, there are still some fundamental ...
Atmospheric aerosols have played a key role in the development of the Earth’s atmosphere. Without atmospheric particles rainfall would be nonexistent and the climate would be very different. However, anthropogenic emissions ...
In this thesis, we will study the superfluidity of condensed atomic and photonic systems, through the manipulation of rotational states, such as vortices or persistent currents. We will study Bose-Einstein condensates both ...
This thesis is devoted to the study of the planar regime of N = 2 Lagrangian 4−dimensional superconformal field theories. In the first part of the thesis we study the matrix models that describe such theories upon performing ...
El trabajo presentado en esta tesis ha sido desarrollado en colaboración entre la empresa Francisco Albero S.A.U. (FAE) situada en L’Hospitalet de Llobregat (Barcelona, España) y el Institut de Recerca en Energia de Catalunya ...
[cat] En la actualitat les dades obtingudes amb instruments de teledetecció (mesures obtingudes a distància) formen una part essencial en l’àmbit de la meteorologia. Aquestes dades s’obtenen amb diversos sensors de tipus ...
The main goal of this thesis is to test the Standard Model (SM) of particle physics through the experimental analysis of rare processes, those that are suppressed in the SM. In particular, radiative b and rare strange ...
In this thesis, we explore different ways in which spacetime exhibits peculiar properties when subjected to the rules of quantum mechanics. These rules are naturally implemented at the level of semiclassical physics, where ...
