[spa] El desarrollo de microambientales artificiales ordenados en un formato de microarray (microarrays celulares, también conocidos en inglés como "cellular microarrays") se ha propuesto como una herramienta que permite ...
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, ...
Nowadays mono- and multicrystalline silicon have the highest market share of all PV technologies but thin film solar cells based on CdTe or Cu(In,Ga)Se2 (CIGS) absorbers recently show promising high power conversion ...
The present doctoral thesis is framed in the research and development (R & D) project between a private biotechnology company of molecular diagnostics Genomica SAU, the Institute for Bioengineering of Catalonia (IBEC), the ...
RÉSUMÉ:<br/><br/>Dans ce mémoire, nous avons proposé une méthodologie de conception originale basée sur un concept de puits flottant permettant de rendre immune au "latch-up" une technologie CMOS/DMOS de puissance intelligente ...
La tecnología microelectrónica esta entrando a formar parte de la vida cotidiana. Así, además del ordenador PC, tanto en los vehículos, como en las viviendas es difícil encontrar equipos o subsistemas eléctricos que no ...
La interacció de la llum amb els òxids metàl.lics (MOX's) semiconductors, sempre i quan l'energia dels fotons sigui superior a l'amplada de la banda prohibida, produeix un increment significatiu de la densitat de portadors ...
The present thesis is included in the field of nanobioelectricity. That is, understanding the electrical properties of biological specimens at the nanoscale (< 200 nm). To do so we used an electrical variation of the ...
The assessment of the electrical properties of biomolecules at the nanoscale becomes necessary for gathering previous basic knowledge and for the control of the biosensor fabrication. I developed instrumentation, protocols, ...
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 ...
In the Transmission Electron Microscope (TEM), an incident electron suffers both elastic and inelastic scattering by the solid state thin sample that is being characterised. In the event of inelastic scattering, the incident ...
The main topic of this thesis is the theoretical and computational investigation of the opto-electronic properties of large arrays of semiconductor quantum dots embedded in an insulator matrix. For that purpose, an electronic ...
Bona part dels processos naturals i de les activitats humanes impliquen processos de transferència d’energia, que en part, o en la seva totalitat es dissipen en el medi. L’aprofitament de l’energia residual present en ...
The significant development in medical diagnostics and imaging has brought up a lot of new wireless capsule endoscopes coming to health care market. The capsule has been able to minimize patient discomfort and pain during ...
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 ...
L'espectroscòpia òptica dels ions Tm3+ i Yb3+ en tungstats dobles monoclínics és molt important per desenvolupar dispositius làser d'estat sòlid. Els tungstats dobles monoclínics són molt interessants pels avantatges que ...
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, ...
Patterns are a collection of forming units predictably repeated over a defined magnitude. Researchers have used patterns to guarantee the functionality and repeatability of their study. For that, the obtained data is ...
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 ...
The work developed during this PhD has embraced several topics that I divide in three blocks. Each block contains two chapters in this dissertation. Additionally, a general introduction of the different topics is provided ...
