In this report novel materials for advanced applications are studied by means of the latest microscopy technologies and methodologies which have had a dramatic impact on progress of materials science. The aim was to study ...
In this thesis, pH and potassium all-solid-state ISE based on potentiometry and bioimpedance sensors were designed, fabricated and integrated in a miniaturized array for its application in endoscopic surgery for in vivo ...
Esta tesis doctoral resume el trabajo realizado en el Departamento de Electrónica de la Facultad de Física, en la Universidad de Barcelona. El objetivo de la misma se centra en el diseño y fabricación de un microsistema ...
The next generation of particle colliders will be characterized by linear lepton colliders, where the collisions between electrons and positrons will allow to study in great detail the new particle discovered at CERN in ...
In the last decades, there has been a huge proliferation of portable devices. Among them, consumer electronics such as mobile phones, music players, e-books, etc. are greatly extended. In order to provide these ...
La tecnologia thick film pot definir-se com el procés on es du a terme la creació de dipòsits de circuits impresos en un substrat de ceràmica rígida mitjançant la tècnica de la serigrafia. Les pastes que s’utilitzen per ...
El trabajo se ha centrado en el análisis del compuesto Cu2ZnSnS4 (CZTS) mediante la técnica de espectroscopia de dispersión Raman, para una mayor optimización de los procesos de crecimiento de capas absorbedoras y la ...
The main goal of this thesis is to combine electron tomography and electron energy loss spectroscopy (EELS) in the TEM, in order to obtain chemical and electronic information in 3D in the nanoscale. Tomography in the ...
The aim of this thesis is to present a solution for the readout of Silicon Photo-Multipliers (SiPMs) arrays improving currently implemented systems. Using as a starting point previous designs with similar objectives a novel ...
This thesis presents the results of applying new strategies to understand the mechanism and explore the sensing performance of metal oxide (MOX) nanowire based gas sensors by testing individual nanowire gas sensors, running ...
Carbon can be found or synthesised in different arrangements, each one with its particular properties. Curiously, the main building block of the majority of these structures (graphene) was first isolated in 2004 by A.K ...
En esta tesis se usa la estrategia de “Bottom-up” para la producción de materiales termoeléctricos nano-estructurados con alta eficiencia termoeléctrica. Esta técnica proporciona un amplio rango de posibilidades para ...
En esta memoria se recogen los resultados sobre preparación y caracterización de las propiedades físicas de sistemas magnéticos nanoestructurados. Para la fabricación de las nanoestructuras se han empleado dos estrategias ...
Introduction It is undisputed that the silicon became the material most widely used in electronics in recent decades[1,2]. The qualities of silicon are well known, from its abundance and low cost to its ability to easily ...
Thin film solar cell technologies are rapidly developing, and chalcopyrite (Cu(In,Ga)Se2) based devices have demonstrated the highest power conversion efficiencies on the laboratory scale. However, in spite of this promise, ...
The rationale for a telemedicine system is the use of Information and Communications Technology (ICT) for the remote transmission of biomedical data and the remote control of biomedical equipment, in order to improve the ...
En esta tesis doctoral se ha estudiado de forma sistemática la relación entre los campos eléctricos y las células, y los efectos que éstos tienen a diferentes niveles (supervivencia, metabolismo, expresión proteica, ...
Nanomaterials have received increasing attention during the last decades in the solid state field since they play a major role as catalyst and catalyst supports for many applications including fuel cells or gas sensors. ...
This thesis aims the development of a multi-electrode platform with applications on different biosensing fields: (i) detection of pathogenic bacteria E.coli O157:H7 and (ii) detection of the mycotoxin Ochratoxin A. For ...
This thesis presents experimental work on developing rare-earth ions and Si nanostructures as a material platform for light emitting devices (LEDs) in the visible and near-infrared range. The realization of the different ...
