[eng] The overwhelming evidence for the existence of dark matter in the Universe, and the discovery of the neutrino masses, are striking indicators of the need for new physics beyond the ΛCDM and Standard Model paradigms. ...
Biset Peiró, Martí (Data de defensa: 2022-01-21)
One of the most serious challenges facing society is the need to reduce the emissions of greenhouse gases such as carbon dioxide (CO2), mainly caused by the widespread use of fossil fuels. The energy transition to renewable ...
Moyà Anderico, Laura (Data de defensa: 2021-04-26)
Galleria mellonella (greater wax moth) is a popular animal model that has been extensively used as an alternative in vivo model for investigating the virulence and pathogenicity of different bacteria. G. mellonella has ...
Zhang, Chaoqi (Data de defensa: 2022-07-04)
Lithium-sulfur batteries (LSBs) are regarded as the most promising candidate to replace Lithium-ion batteries (LIBs) in next-generation energy storage systems. Compared with LIBs, LSBs are characterized by a sixfold higher ...
Molina, Alfred (Data de defensa: 1976-01-14)
En este trabajo se evalúan cuidadosamente los elementos de matriz nucleares reduciendo muy considerablemente la imprecisión en los resultados finales. Por otra parte por primera vez se consideran posibles transiciones a ...
Fuentes Fuentes, Edgar (Data de defensa: 2023-02-17)
[eng] A strategy that is being intensively explored to efficiently deliver pharmaceuticals involves drug delivery systems. These carriers should greatly improve the pharmacokinetics of drugs, while providing a selective ...
Plana Ruiz, Sergi (Data de defensa: 2021-01-27)
The application of electron diffraction to crystallographically characterize all kinds of materials has experienced new developments that have attracted some attention in recent years. A large number of structural analyses ...
Juvert Sández, Joan (Data de defensa: 2014-07-04)
We have characterized electroluminescent devices based on silicon rich oxide and/or silicon rich nitride. We have discussed the photoluminescence and structural characterization of the active layers and the electrical and ...
Corrêa Volpini, Bruna (Data de defensa: 2021-12-13)
In the late 1990's, when sophisticated personal computers and electronic devices with miniaturized sensors were being mass produced, the concept of ambient intelligence (AmI) emerged. An environment ...
Trindade, Ana Filipa Mestre (Data de defensa: 2023-01-16)
[eng] Heat, moisture, gas, and momentum exchanges at the oceanic and atmospheric interface modulate, inter alia, the Earth’s heat and carbon budgets, global circulation, and dynamical modes. Sea surface winds are fundamental ...
Torruella Besa, Pau (Data de defensa: 2019-04-26)
[eng] The aim of this thesis has been two-fold. First, to develop new processing and analysis tools and strategies for extracting information from EELS data, and second, to apply the methods to different nanoparticle systems ...
Rueda García, Daniel (Data de defensa: 2020-09-15)
Flow cells are on their way to become a key player for electrical energy storage (EES) thanks to their suitability as load-levelling devices thus contributing to the development of smart grid and to offset the intermittency ...
Bola Sampol, Raúl (Data de defensa: 2021-06-17)
To ensure progress in the field of biomedicine and drug development, it is essential to keep improving the equipment needed to carry out most of the experiments. With better tools, scientists can be more efficient, increasing ...
Hernández Martínez, Alejandro (Data de defensa: 2019-11-26)
This thesis is devoted to the development of new annealing strategies via Rapid Thermal Processing (RTP) for Earth-abundant Cu2ZnSn(Sx,Se1-x) (CZTSSe) kesterite solar cells, which show a clear consensus amongst the scientific ...
García Lizarribar, Andrea (Data de defensa: 2022-01-28)
In vitro engineered three-dimensional tissue models are attracting an increasing interest due to their potential applications in preclinical assays. On the one hand, they are an alternative to the high costs, ethical issues ...
Sanglás Martín, Albert (Data de defensa: 2023-10-10)
[eng] This thesis investigates primordial black holes and their observational consequences. In the first part, we examine the behavior of domain walls produced during inflation, and their subsequent collapse, leading to ...
