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 (Fecha 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 (Fecha 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 (Fecha 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 ...
Sierra Agudelo, Jessica Nathalia (Fecha de defensa: 2024-02-23)
[eng] The emergence of liquid biopsies has been useful for the diagnosis of physiological conditions, inflammatory processes, and especially represents a good alternative tool for non-invasive analysis of tumor-derived ...
Torruella Besa, Pau (Fecha 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 (Fecha 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 ...
