Rojas-Cervellera, Víctor (Date of defense: 2015-07-17)
Thiolate monolayer-protected gold clusters (AuMPCs) are being used in various biological and biomedical applications due to their unique physical and chemical properties. The fact that gold-sulphur bonds are very stable ...
Cikojević, Viktor (Date of defense: 2021-04-20)
The properties of mixtures of Bose-Einstein condensates at T=0 have been investigated using quantum Monte Carlo (QMC) methods and Density Functional Theory (DFT) with the aim of understanding physics beyond the mean-field ...
Beltrán González, Martí (Date of defense: 2021-01-22)
Materials and methods used in the production of modernist (late 19th and early 20th century) stained glass from the city of Barcelona with special regards to the degradation mechanisms of enamels, grisailles and silver ...
Monterrubio Velasco, Marisol (Date of defense: 2013-03-15)
Mediante el análisis estadístico y utilizando diversas técnicas fractales en esta tesis se estudia el comportamiento temporal y espacial de tres series de réplicas sísmicas ocurridas en el Sur de California, que tuvieron ...
Kvashin, Nikolai (Date of defense: 2022-11-16)
(English) The mechanical properties of structural materials, which are naturally polycrystalline, is defined by a number of physical processes that take place at different time and space scales. On several of those processes, ...
Zeng, Ming (Date of defense: 2024-12-04)
(English) At present, HFC refrigerants with a global warming potential of thousands of times that of CO2, are widely used in air conditioners and, refrigerators. Due to lack of maintenance and poor management, and low or ...
Aznar Luque, Araceli (Date of defense: 2021-04-15)
Current refrigeration devices, based on vapour-compression cycles, employ refrigerants such as HFCs, which exhibit a global warming potential a thousand times higher than the one produced by CO2,. Furthermore, the increasing ...
Suñol Galofré, Francesc (Date of defense: 2011-07-19)
Two-phase flows are encountered in a wide range of applications both on-ground and in space. The dynamics of such flows in the absence of gravity is completely different from that in normal gravity due to the absence of ...
Arcos Gutiérrez, David (Date of defense: 2022-07-19)
Two-dimensional materials have a lot of applications in the electronic and photonic device design field, especially when they need to be flexible and transparent. In particular, high frequency applications, above 100MHz, ...
Silini, Riccardo (Date of defense: 2022-07-05)
To advance time series forecasting we need to progress on multiple fronts. In this thesis, we develop algorithms to identify causal relations which allow to identify the driving processes containing useful information for ...
Duarte Correa, María Jazmín (Date of defense: 2013-05-31)
Metallic glasses are often referred as glassy or amorphous alloys. They lack long-range order and microstructural defects that are characteristics in crystals, such as grain and phase boundaries and dislocations. These new ...
Deza, Juan Ignacio (Date of defense: 2015-02-26)
This Thesis is devoted to the construction of global climate networks (CNs) built from time series -surface air temperature anomalies (SAT)- using nonlinear analysis. Several information theory measures have been used ...
Múgica Gallart, Julia (Date of defense: 2023-06-07)
(English) Collective behavior in animals is ubiquitous in nature. It emerges from the self-organization of interacting individuals within a group. What makes collective behavior so interesting is that the behavior of the ...
Molina Giralt, Glòria (Date of defense: 2014-05-09)
Historical decorated glass and glazed ceramics are studied with the object to determine the technology of production and to relate it with the optical properties (colour, shine, opacity). Four different case of study are ...
Vurgun, Eda (Date of defense: 2024-11-07)
(English) The thesis deals with millisecond pulsars (MSPs), a fascinating group of neutron stars distinguished by their exceptionally fast rotation periods (Ps < 30 milliseconds) and their strong magnetic fields (of the ...
Moreno Ramos, Eduardo (Date of defense: 2022-05-30)
Cell motility is important in many biological processes. Some examples relay in epidermal cells moving towards lesions during wound healing, neutrophils cells migrating towards sites of bacterial infection as part of the ...
Tahat, Amani Naser (Date of defense: 2016-06-01)
This thesis aims at studying the microscopic physical-chemical properties of an excess proton in aqueous systems. From bulk water environments to narrow hydrophobic channels constructed with a double-layered graphene slab, ...
Sánchez Casals, Odalys (Date of defense: 2015-11-10)
The modelling of convective transport processes involving heat and mass transfer in an incompressible Newtonian fluid in cylindrical domains is a relevant research subject both for theoretical research and for industry. ...
Sánchez Baena, Juan (Date of defense: 2020-12-14)
The main goal of this thesis is the computation of ground state properties of quantum many-body systems under Spin Orbit coupling (SOC) interactions out of the ultradilute regime. We present two approaches to fulfill this ...
Xie, Chenyang (Date of defense: 2021-01-08)
