Ramon Gamon, Jaume (Data de defensa: 2022-01-27)
Multiple initiatives are being implemented to mitigate and, in the worst-case scenarios, adapt society to climate change. The vast majority consider renewable energies key to accomplishing a necessary transition from fossil ...
Han, Tingting (Data de defensa: 2020-12-11)
With the burning of large amounts of traditional fossil fuels, global environmental pollution is getting worse and worse, and energy crisis is becoming more serious for meeting human’s life demand. In ...
Pravos Fernández, David (Data de defensa: 2019-11-08)
This thesis describes some results in AdS/CFT duality for quantum field theories in 2+1 and 1+1 dimensions. In first place, a one-parameter family of supergravity solutions is described, obtained as a deformation of a ...
Sanchez Garitaonandia, Mikel (Data de defensa: 2022-07-15)
Cosmological thermal first-order phase transitions are assumed to proceed via the nucleation of bubbles and subsequent expansion and collision. The out-of-equilibrium physics involved during the collision of bubbles is ...
Valcin, David (Data de defensa: 2021-09-28)
CONTEXT: The current ΛCDM cosmological paradigm has seen remarkable success in recent decades (whether it is the discovery of the CMB, the formation of large-scale structures, the expansion of the universe etc.). Like any ...
Amato, Roberta (Data de defensa: 2018-04-13)
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 ...
Mestre Castillo, Rafael (Data de defensa: 2020-11-26)
Hybrid bio-robotics is a discipline that aims at integrating biological entities with synthetic materials to incorporate features from biological systems that have been optimized through millions of years of evolution and ...
Navarro Argemí, Eloy (Data de defensa: 2018-10-25)
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 ...
Vila Giraut, Anna (Data de defensa: 2020-12-10)
Conventional in vitro cell culture models do not possess the complexity that the native tissues offer. Because of this, the functional properties of the tissues are not properly mimicked, which causes poorly predictive ...
Rodríguez Domínguez, Laura (Data de defensa: 2021-12-16)
A Metal-insulator transition (MIT) is the ability of some materials to change between metal and insulator electric behaviours as a function of some external stimuli such as temperature, stress, voltage, magnetic field or ...
Weber, Jonas (Data de defensa: 2024-04-11)
[eng] Owing to its exceptional topographical resolution and electrical sensitivity, Conductive Atomic Force Microscopy (C AFM) has become an essential tool for nanoscale material analysis. However, achieving reproducible ...
Turquet, François-Xavier (Data de defensa: 2018-12-17)
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, ...
Pla i Asesio, Dolors (Data de defensa: 2015-07-31)
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 ...
Llabrés Brustenga, Alba (Data de defensa: 2020-01-14)
Intensity - Duration - Frequency (IDF) relationships of extreme precipitation events are of high interest in hydrology. The building of infrastructure or designation of flood zone need, as groundwork, the recurrence intervals ...
Fernández Varea, José María (Data de defensa: 1992-07-27)
The interaction of electrons with matter has been a subject of intense work since the beginning of the century. Although we know that the interaction is purely electromagnetic, its theoretical description is ...
Chiabrera, Francesco Maria (Data de defensa: 2019-06-28)
Interface-dominated materials such as nanocrystalline thin films have emerged as an enthralling class of materials able to engineer functional properties of transition metal oxides widely used in energy and information ...
Almici, Enrico (Data de defensa: 2022-10-10)
[eng] The composition and architecture of the extracellular matrix (ECM), and their dynamic alterations, play an essential regulatory role in numerous cellular processes. Furthermore, structural, and biochemical properties ...
Pablos Alonso, Daniel (Data de defensa: 2016-06-22)
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 ...
Espindola Rodriguez, Moises (Data de defensa: 2015-07-23)
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 ...
Sopeña i Martínez, Pol (Data de defensa: 2020-12-16)
Printed electronics appeared in the 1980s as a cost-effective alternative to silicon-based electronics. Employing the techniques from the graphics industry, such as rotogravure or screen printing, it was possible to print ...
