Advancing cancer precision medicine through cell-based functional assays and microfluidics. Finding the needle in a haystack to improve pediatric leukemia treatment
[eng] Personalized medicine has emerged to improve cancer treatment beyond classical approaches. The identification of genetic mutations by molecular analyses dominate personalized medicine initiatives promoting clinical ...
Algorithms for light applications: from theoretical simulations to prototyping
[eng] Although the first LED dates to the middle of the 20th century, it has not been until the last decade that the market has been flooded with high efficiency and high durability LED solutions compared to previous ...
Functional design of nanocomposites and their applications in energy conversion and storage
[eng] This thesis focuses on the functional design and preparation of different kind of nanocomposites and their applications in energy conversion and storage technologies, particular in OER, HER, H2O2ER and LSBs. For the ...
Investigating pathological extracellular matrix architecture
[eng] The composition and architecture of the extracellular matrix (ECM), and their dynamic alterations, play an essential regulatory role in numerous cellular processes. Furthermore, structural, and biochemical properties ...
Making the most of imaging and spectroscopy in TEM: computer simulations for materials science problems
[eng] Transmission Electron Microscopy (TEM), since its first implementation by Ernst August Friedrich Ruska and Max Knoll in 1931, has been an essential technique in the nanoscience and nanotechnology field. In the ...
Engineered functional 3D spheroids for β-cell encapsulation
[eng] Type 1 Diabetes Mellitus (T1DM) is known to be associated with the immune-mediated destruction of insulin-secreting β-cells. Cell replacement therapy is thought to be a potential long-lasting cure for diabetes. In ...
Multiscale Modeling of Organic Electronic Biosensor Response
[eng] There have been significant advances in organic bioelectronic devices in recent years. These devices are capable of stimulating excitable cells and can generate data to facilitate disease diagnostics and monitoring. ...
Cobalt-based Nanocatalysts for Electrochemical Energy Conversion
Cobalt-based nanomaterials are an important class of electrocatalysts that own abundant and diverse d-orbital electronic structures, and can exhibit excellent HER, OER, EOR catalytic activity and stability in energy ...
Complex Oxide Heterostructures for Spin Electronics
The direct manipulation of spin currents with no charges involved along with the delicate interplay between charge, spin and orbital degrees of freedom in materials and structures has attracted a renewed interest in the ...
Holographic Phase Transitions and Gravitational Waves
Cosmological thermal first-order phase transitions are assumed to proceed via the nucleation of bubbles and subsequent expansion and collision. The out-of-equilibrium physics involved during the collision of bubbles is ...
Design and Engineering of Advanced Cathode Hosts for Lithium-Sulfur Batteries
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 ...
The Planar Limit of N=2 Superconformal Field Theories
This thesis is devoted to the study of the planar regime of N = 2 Lagrangian 4−dimensional superconformal field theories. In the first part of the thesis we study the matrix models that describe such theories upon performing ...
Metal selenide-based cathodes for high-performance lithium-sulfur batteries
Lithium-sulfur batteries (LSBs) have attracted extensive research interest for the development of advanced energy storage technology. However, the practical implementation of LSBs still suffers from several intractable ...
Statistical detection of tidal streams generated by globular clusters and their application to measure the axis ratio of the Milky Way dark matter halo
In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish stream ...
Wide bandgap chalcogenide thin films onto transparent substrates
This PhD thesis explores the use of wide band gap chalcopyrite (CIGS) material and its application in thin film solar cells onto transparent back contacts, as a way to promote the use of thin film technologies in novel and ...
From Dynamics to Structure of Complex Networks: Exploiting Heterogeneity in the Sakaguchi-Kuramoto Model
Most of the real-world complex systems are best described as complex networks and can be mathematically described as oscillatory systems, coupled with the neighbours through the connections of the network. The flashing of ...
Medidas de la función de transmisión policromática en sistemas fotográficos y su correlación con la calidad de imagen
A finales del siglo pasado Abbe y Rayleigh observaron que los fenómenos de difracción limitaban el poder resolutivo de los instrumentos ópticos. La teoría clásica de aberraciones justificaba también el valor finito del ...
Sistemas dinámicos de dimensión finita con ligaduras
Aparte del atractivo meramente matemático, el interés físico del estudio de los sistemas dinámicos con ligaduras reside en un hecho fundamental: sólo las teorías físicas cuya dinámica esté descrita por una lagrahgiana ...
Corrección automática de sistemas ópticos mediante marchas exactas de rayos
Los métodos de cálculo y corrección de sistemas ópticos sufrieron una total revolución hacia 1950 con la aparición de las calculadoras electrónicas programables. Su rapidez y potencia de cálculo permiten abordar los ...
Estudi dinàmic d'un sistema d'N cossos extensos, carregats i gravitants
La solució del problema d'N cossos a la Teoria General de la Relativitat requereix la determinació, al mateix temps, del camp gravitatori deIs cossos considerats. La solució a aquest problema fou donada per primera vegada ...
