Du, Ruifeng (Date of defense: 2022-06-30)
[eng] This thesis focuses on the functional design and preparation of different kind of nanocomposites and their applications in energy conversion and storage technologies, particular in OER, HER, H2O2ER and LSBs. For the ...
García Pérez, Guillermo (Date of defense: 2018-11-16)
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 ...
Katuri, Jaideep (Date of defense: 2018-09-20)
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 ...
Ramon Gamon, Jaume (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 ...
