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 ...
Pablos Alonso, Daniel (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 ...
Statuto, Nahuel (Date of defense: 2019-07-22)
The goal of this thesis is to explore and control the magnetization dynamics on magnetic multilayered thin films through two different techniques: the application of strain and spin- polarized currents, which represent ...
Coll Benejam, Catalina (Date of defense: 2022-10-26)
[eng] Transmission Electron Microscopy (TEM), since its first implementation by Ernst August Friedrich Ruska and Max Knoll in 1931, has been an essential technique in the nanoscience and nanotechnology field. In the ...
Ortiz Castillo, Elisenda (Date of defense: 2022-01-13)
Complex systems, which involve a massive ammount of components interacting in nontrivial ways and exhibi- ting properties such as emergence, feedback-loops and self-organization, permeate our world to an unthinkable extent. ...
Cervera Lierta, Alba (Date of defense: 2019-06-21)
The aim of this thesis is to study the quantum entanglement and, in particular, under which circumstances is maximum. In the first place, Bell's inequalities are analyzed from an operational point of view. In particular, ...
Marqués Truyol, Francisco (Date of defense: 1980-09-18)
A la relativitat, a diferència de la mecànica newtoniana, no trobem exemples senzills de sistemes dinàmics de diverses partícules. La formulació covariant Lorentz de les equacions del moviment per a sistemes de partícules ...
Vallmitjana i Rico, Santiago (Date of defense: 1980-01-01)
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 ...
Hoffmann Salvaña, Xavier Roderic (Date of defense: 2021-09-21)
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 ...
Yang, Dawei (Date of defense: 2022-07-01)
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 ...
Millán Solsona, Rubén (Date of defense: 2023-07-10)
[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 ...
Parmar, Jemish (Date of defense: 2018-10-05)
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 ...
Huetter, Larissa (Date of defense: 2022-09-30)
[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. ...
Tanwar, Shubham (Date of defense: 2023-07-28)
[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 ...
