This thesis consists in the development of a new methodology of α-alkylation of carbonyl compounds and its application to the synthesis of small molecules with therapeutic interest. In this context, the alkylation of ...
Hace unos años, en el grupo de investigación donde se ha realizado esta Tesis Doctoral, se estudió un sistema de oro(I)-alquinilo con una fosfina soluble en agua, que dio lugar a la formación de un hidrogel. Este ejemplo ...
El siguiente trabajo recopila los resultados conseguidos durante el transcurso del periodo Doctoral, el cual se divide en dos secciones: la primera sección aborda distintos estudios sobre reacciones organocatalíticas, ...
En esta tesis se abordan diferentes problemas químicos relacionados con situaciones inusuales de enlace en moléculas. Para algunos de estos problemas se ha aplicado el análisis de pseudosimetría de los orbitales moleculares, ...
El uso de complejos inertes de metales de transición en procesos en los que se involucran moléculas biológicamente relevantes es un sistema ampliamente estudiado en la actualidad. El ejemplo a destacar de estos estudios ...
[eng] This thesis is mainly focused on studying the photophysical properties of Au(I), Ag(I), Cu(I), and Pt(II) coordinated compounds. This work can be divided into two parts: on the one hand, the compounds of the group ...
[eng] Multidrug resistant bacteria have grown to be a significant medical concern as a result of decades of excessive antibiotic usage and overuse in human medicine, agriculture, and the animal industry. In this context, ...
Les nanopartícules de metalls nobles han atret l’interès dels investigadors en els últims anys degut a la seva elevada activitat i selectivitat en un gran nombre de reaccions catalítiques. No obstant això, les nanopartícules ...
c-Src is a non-receptor tyrosine kinase that controls numerous cellular signaling pathways. c-Src implication in human cancers was brought into the attention in the 1980s. Since its discovery, unveiling of c-Src ...
En la primera parte de esta tesis, se basó en la síntesis de ligandos basados en la heptazina y los complejos formados con CuII. Utilizando 2-dipiridilamina para funcionalizar el núcleo de heptazina, (ligando que presenta ...
During the last years, the research group where this Doctoral Thesis has been carried out has been pioneer in the development of different gold(I) complexes and resulting supramolecular assemblages with a wide variety of ...
Los materiales piezoeléctricos basados en el titanato zirconato de plomo (PZT) son ampliamente utilizados en una gran cantidad de dispositivos electrónicos debido a sus excelentes propiedades eléctricas. Esta mejora de las ...
Carbohydrates are essential molecules in biotechnology and for the proper functioning of living organisms. They are involved in energy storage, being structural components or participating in crucial biological processes ...
In this doctoral thesis a series of computational and experimental studies of molecular magnetoresistance devices at room temperature is presented. This sort of devices is included in the molecular electronics framework ...
The Thesis is based on the development of a potentially-scalable methodology to prepare polyurethane/polyurea polymers to nanoencapsulate bioactive molecules. In the first part of the project, the design, optimization and ...
The main contribution of this doctoral thesis has been devoted to the field of synthetic organic chemistry. The Pauson-Khand reaction (PKR) is a metal-catalyzed [2+2+1] cycloaddition between an alkyne, an alkene and a ...
[eng] The increasing demand on next-generation displays encourages an exhaustive research on the development of new and enhanced semiconductors. Apart from the conventional inorganic materials, organic-based semiconductors ...
In this work, the effect of CO2 on the hydrogen production under substoichiometric ethanol steam reforming (ESR) conditions over nickel based catalysts was studied. A special emphasis was focused on the application of ...
L'objectiu principal d'aquesta Tesi doctoral ha estat l’obtenció d’una via alternativa a les existents per a l'obtenció d'un intermedi clau, 1, en la síntesi d'un fàrmac anticoagulant. La nova via havia de ser novedosa i ...
After decades of exorbitant antibiotic misuse and overuse in human medicine, agriculture and livestock industry, multidrug resistant bacteria (MDR) have become a major medical concern. In this regard, the design of new, ...
