In this thesis we asses the phenomena of arising interactions in soft matter in coexistence with soft active matter. As a non-equilibrium bath we introduce ensembles of self-propelled particles, granular shaken beds, and ...
Brownian motion refers to the random movement that undergo mesosized particles suspended in a simple sol- vent. Einstein’s probabilistic approach to the Brownian motion is founded on the principal that it is on account of ...
[eng] Geometrical frustration is a general phenomenon influencing the behavior of diverse natural systems across different length scales. Geometrical frustration arises when the symmetry of the interaction among building ...
This thesis was part of the European consortium MESOBRAIN, a team of 5 organizations that joined efforts in nanofabrication, cell culturing, imaging and data analysis to build tailored human 3D networks. The thesis timing ...
In this thesis, we have studied mechanical aspects of some biological processes in cells and tissues, which we addressed by developing theoretical models based on the physics of soft active matter. The thesis contains three ...
Single-molecule experiments have emerged as a powerful tool that allow researchers to investigate the physical behavior of individual molecules with unprecedented resolution. The feasibility exerting forces at the piconewton ...
[eng] One of the greatest challenges in the field of neuroscience is to obtain an accurate functional description of the brain that allows us to understand the functioning of higher complexity cognitive processes such ...
The urgent need to reduce our footprint on the earth environment is leading to ever more stringent commitments to decrease greenhouse gases emissions, which entails one of the greatest challenges that mankind has to tackle. ...
Solid state materials are candidates to exhibit a large field-driven thermal response in the vicinity of first-order transitions. The strong sensitivity of the transition temperature with the applied field and the latent ...
In the present thesis, we propose to explore neuronal circuits at the mesoscale, an approach in which one monitors small populations of few thousand neurons and concentrates in the emergence of collective behavior. In our ...
Membranes are present in all cells, in some viruses, and are involved in all kinds of biological functions. The goal of this thesis is to expand our knowledge of this element, in hope that this -on top of all the other ...
This thesis is devoted to the nanofabrication, simulation and optical characterization of different plasmonic nanostructures. When an electromagnetic wave reaches a metallic nanostructure, it can give rise to collective ...
[eng] In this thesis, I study the behavior of confined colloidal particles in aqueous suspension driven through an optical potential. For this purpose, I use micro-meter polystyrene particles, which I confine in the optical ...
The development of living systems, from their conception to their death, involves a very tight coordination between gene expression in time and space. The processes involved in such an unfolding do not solely depend on the ...
In this thesis we investigate the structure formation and the out-of-equilibrium dynamics of driven and active magnetic colloids. The interactions in our system were tuned in situ by using external fields, with the aim of ...
Throughout this thesis we have assessed the prospects of microwave spectrometry (MWS) as a non-ionizing non-invasive monitoring alternative for stented patients in a very early proof-of-concept stage. In Chapter 1 we have ...
The study of DNA from atomistic to mesoscopic level and connecting different resolution levels constitutes a major challenge since the new millennium. In the early 2000s, experiments could resolve for the first time the ...
Intercellular signalling is a mechanism by which cells communicate and mediate coordinated responses. In this Thesis we perform theoretical and computational analyses to evaluate spatio-temporal organizations that can arise ...
Two main topics are examined in this thesis: classical systems with long-range interactions and thermal radiation in the near-field regime. In the first part, we present a thermodynamic approach describing systems with ...
