A finales del siglo pasado Abbe y Rayleigh observaron que los fenómenos de difracción limitaban el poder resolutivo de los instrumentos ópticos. La teoría clásica de aberraciones justificaba también el valor finito del ...
Epidemic modeling has proven to be an essential framework for the study of contagion phenomena in biological, social, and technical systems. Albeit epidemic models have evolved into powerful predictive tools, most assume ...
Lithium-sulfur batteries (LSBs) have attracted extensive research interest for the development of advanced energy storage technology. However, the practical implementation of LSBs still suffers from several intractable ...
[spa] Las propiedades dieléctricas de las células han sido objeto de una intensa investigación a lo largo de los años debido a su relevancia en muchos problemas biológicos fundamentales. Destacamos la importancia de la ...
Scarce supply of clean water and rising water pollution are key global challenges for water sustainability. Much of the wastewater generated by human agricultural and industrial activity is left untreated. Nanotechnological ...
[eng] There have been significant advances in organic bioelectronic devices in recent years. These devices are capable of stimulating excitable cells and can generate data to facilitate disease diagnostics and monitoring. ...
[eng] Electrolyte-gated transistors (EGTs) have emerged as key platforms for transducing and amplifying biological and biochemical signals, making them an integral part of diverse biosensing and bioelectronic applications ...
Storing the fluctuating renewable energy into synthetic fuels or in batteries is meaningful due to the emerging energy crisis. In this thesis, four nanostructured catalysts based on two kinds of metal sulfides, namely Cu2S ...
El Niño Southern Oscillation arises in the tropical Pacific due to coupled atmosphere-ocean interactions. The nature of the dynamical system of the atmosphere is chaotic and its predictability is sensitive to initial ...
The current trend in exoplanet research focuses on the detection and characterisation of Earth-sized planets, and the study of their potential subtle and tenuous atmospheres. The aim of this thesis is the development of ...
In this thesis we apply new approaches and develop new techniques to address various issues related to fundamental aspects of modern gravitational theory and black holes. We study the behavior of black branes in the ...
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 ...
