Spatial embedding and inherited metric constraints are a fundamental trait of biological neuronal circuits. However their role in shaping connectivity and dynamics has been often disregarded, with models of neuronal networks ...
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, ...
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 ...
This thesis focuses on different aspects of NCs colloidal synthesis, the exploration of the relevant surface chemistries that afford NC assembly and the NC implementation into porous nanomaterials. The work is divided ...
El campo que estudia las propiedades y comportamiento de las proteínas así como las interacciones entre ellas es tan complejo que a día de hoy resulta complicada su caracterización en detalle, sea utilizando herramientas ...
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 ...
Electronic machines and computers have experienced a huge development during the last four decades, mainly thanks to the continuous scaling down of the hardware responsible of information processing and storage (i.e. ...
Living organisms and systems are continually converting energy, either internally stored or transduced from their surroundings, into motion. This activity and the resulting self-propulsion constantly push these biological ...
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 ...
The goal of this thesis is studying hydrodynamic effects on active colloidal suspensions. Hydrodynamic interaction is propagated through the fluid in which the colloids displace due to the flow they create during their ...
Complex networks are mathematical representations of the interaction patterns of complex systems. During the last 20 years of Network Science, it has been recognized that networks from utterly different domains exhibit ...
The need of substituting the current energetic model by a system based on clean Renewable Energy Sources (RES) have gained more importance in the last decades due to the environmental issues related to the use of fossil ...
ROS (Reactive Oxygen Species), such as H2O2, HO● and O2-●, are naturally produced by the metabolism of living beings. However, they can appear in large quantities in the case of certain diseases (Alzheimer's, Parkinson's, ...
The first confirmed detection of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found by radial velocity measurements in a four-day orbit around the nearby star 51 Pegasi by Mayor and ...
Along this Thesis dissertation book, which is focused on the topic of Redox Flow Batteries, many efforts have been done in order to improve different aspects of the all-Vanadium Redox Flow batteries (VRFBs) technology, as ...
[eng] The aim of this thesis has been two-fold. First, to develop new processing and analysis tools and strategies for extracting information from EELS data, and second, to apply the methods to different nanoparticle systems ...
The Sun is the main source of all kind of solar energetic particles in the Solar System, electrons, protons and ions with energies from few keV to several GeV. These particles are released from the solar corona and spread ...
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 ...
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 ...
AIMS: We develop a new theoretical framework to generate Besançon Galaxy Model Fast Approximate Simulations (BGM FASt) to address fundamental questions of the Galactic structure and evolution performing multi-parameter ...
