Most of the efforts on the search and characterization of Earth-like exoplanets are currently focused on low mass stars. Some important properties related to the structure and processes in this type of stars are still ...
Codification of genetic information; regulation of gene expression; transport of nutrients inside cells; immune protection against infectious agents; transduction of external signals... These are some of the crucial processes ...
This project presents the study of luminescent devices and materials based on silicon for its use in the fabrication of an optical system that integrates light emitter, waveguide, and light sensor in a single chip obtained ...
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 ...
Solar cells generate electrical power by direct conversion of solar radiation into electricity using semiconductors. Once produced, the solar cells do not require the use of water; operate in silence and can be easily ...
In the last decades, energy requirements of portable devices are exponentially increasing while the capacity of the current battery technology is not progressing accordingly. This energy gap claims for the development of ...
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), ...
The revolution of ICT technologies in Digital Era combined with progress of ComplexitySciences have lead to the emergence of Computational Social Science, whose purposeis to analyze society in a quantitative way. ...
Zebrafish heart regeneration remains one of the most interesting phenomena of the 21st century. Considering the extremely high rate of deaths due to cardiovascular diseases in the developed countries, 1 out of every 3 ...
In this thesis we have studied how high energetic excitations propagate through a non- abelian strongly coupled plasma. This new state of matter is produced at heavy ion collisions in our accelerators and allows us to study ...
Online social networks (OSNs) enable researchers to study the social universe at a previously unattainable scale. The worldwide impact and the necessity to sustain their rapid growth emphasize the importance to unravel the ...
Helium is the second lightest element and the second most abundant element in the universe. It is named for the Greek god of the sun, Helios, and it was first discovered by French astronomer Jules Janssen as an unknown ...
Una máxima que se plantea en la sociedad actual es la consecución de una mayor eficiencia en los procesos industriales, reduciendo factores como el peso, mejorando la respuesta con los ciclos de los materiales y sobretodo ...
Biomolecular simulations have been widely used in the study of protein-ligand interactions; comprehending the mechanisms involved in the prediction of binding affinities would have a significant repercussion in the ...
Nowadays, our modern society huge challenges related to energy, savings as well as energy management, to improve and extend the standard of living to a growin population over 7000 million people, and do it with sustainable ...
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 ...
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 main objective of this thesis was to develop high efficiency thin film solar cells based on low-toxic and earth-abundant kesterite Cu2ZnSnSe4 (CZTSe) absorbers through the implementation of innovative doping strategies. ...
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 ...
The topics dealt with in this thesis are all part of the general problem of social consensus, namely how a convention flourish and decay and what motivates people to conform to it. Examples range from driving on the right ...
