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 ...
In recent years, the LOC community has focused most of its research in the biomedical and biotechnology fields, due to the need of portable, low power consumption and low cost theranostics microdevices. Some developing ...
Force plays an essential role in all fields of biology. Measurement of these forces with high precision provides information about the structure, dynamics, intra and intermolecular interactions, and the mechanical properties ...
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 ...
En esta tesis doctoral se estudia la problemática existente en la aplicación de los nanomateriales y la nanotecnología para la preparación de dispositivos basados en tecnología cerámica multicapa. Un punto clave de la ...
Natural vesicles produced from genetically engineered cells with tailored membrane receptor composition are promising building blocks for sensing biodevices. This is particularly true for the case of G-protein coupled ...
Les tecnologies de sensors de gas basades en semiconductors presenten limitacions importants de selectivitat i consum d'energia. Per tant, esdevé necessari l’assaig de nous conceptes de dispositius capaços de satisfer ...
The objective of this thesis is to present a proposal for the analogue signal processing chain needed for the LHCb calorimeter upgrade improving the design used originally. The design contains several novelties: the ...
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 ...
This thesis aims at providing a better understanding of the micro- and nanofabrication of conducting polymers for biomedical devices and presents novel processes that widen the application range of conducting polymers in ...
Thin film solar cells based on direct band gap semiconductors have attracted much research during last decades. Thin film technologies are currently commercial and display record power conversion efficiencies up to 20% at ...
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 ...
This thesis presents the work carried out towards the implementation of RE-doped Si-based light emitting devices as integrated optoelectronic building blocks for Silicon Photonics. This work spans from the fundamentals ...
During the last decades, silicon nanocrystals have focused great attention due to the size-dependent physical properties they present, attributed to the quantum confinement effect. This, added to the bulk silicon compatibility ...
Gene expression is a complex and highly regulated process. Most of the regulation is controlled by short DNA sequences that can be bound by some proteins called transcription factors (TF). Binding to these sites, the ...
There are several applications where the measurement of VOC results to be useful, such as: toxic leaks, air quality measurements, explosive detection, monitoring of food and beverages quality, diagnosis of diseases, etc. ...
This thesis explores the analytical capabilities of low-loss electron energy loss spectroscopy (EELS), applied to disentangle the intimate configuration of advanced semiconductor heterostructures. Modern aberration corrected ...
This thesis is devoted to the study of the interactions of phonons in indium nitride (InN) and materials of the (In,Ga)N system with wurtzite structure. For this purpose, we present Raman spectroscopy on nanowires (NWs), ...
The search for analytical tools suitable for wide-scale application of DNA analysis is an hot research topic, although thanks to well-established microarray based technology, analysis of DNA sequences and SNP detection can ...
The main objective of this thesis is the development of Raman scattering based methodologies for the analysis of advanced electrodeposition-based CIGS technologies, with the identification and characterization of parameters ...
