Disputation: Liquid scintillators as neutron diagnostic tools for fusion plasmas: System characterization and data analysis
The neutrons produced in fusion devices carry information about various properties of the ions that are reacting in the machine. Measurements of the neutron flux and energy distribution can therefore be used to study the behaviour of the plasma ions under different experimental conditions.

Disputation: Luminescence of Silicon Nanoparticles Synthesized by Ion Implantation
Silicon nanoparticles (SiNPs) have been shown to display luminescence in the visible range with a peak wavelength depending on the nanoparticle size. This finding is of potential interest for integration of optoelectronic devices in semiconductor technology. In this thesis, silicon nanoparticles are formed in thermally grown SiO2 films by implantation of Si-ions.

Disputation: Vacua in String Theory: de Sitter and Stability in Flux Compactifications
In this thesis we present some explorations within supergravity, a low energy limit of string theory, studying non-supersymmetric vacua, its stability, and the possibility of finding dS.
