Active turbulence and active shell models for microswimmer suspensions
[eng] This doctoral thesis deals with the study of the collective behavior of active particles using computacional simulations of semi-dilute solutions of microswimmers. Results are obtained for the polar order parameter, ...
3D in vitro models for neural progenitor cell differentiation and network formation
[eng] Conventional 2D in vitro and animal models have been found inadequate to fully uncover the intricate mechanisms happening in the brain and its diseases. Engineering-based models emerge as promising alternatives to ...
Domain walls, primordial black holes and inflation
[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 ...
Towards a better characterization of submicron aerosol in the Mediterranean basin
[eng] Atmospheric aerosol is an ensemble of atmospheric pollutants with a severe impact on human health and Earth climate. Particulate Matter (PM) effects vary depending on the composition and size. However, current air ...
Engineering in vitro models of the intestinal mucosa to study the role of the stroma on the epithelium
[eng] The standard in vitro model of the small intestine in the field of drug development still consists in a monolayer of cancer-derived cells seeded on a hard substrate. Despite the huge advances that this model has ...
