The size/shape dependent and unique physical and chemical properties presented by nanostructured materials have attracted great attention in several fields such as energy harvesting, optoelectronics and biomedicine, among ...
Following the laws of evolution, bacteria are capable of slowly but inexorably acquiring resistance to antibiotic compounds that we have been using for decades. Therefore, bacteria that seemed harmless to most people (such ...
Spin crossover (SCO) complexes and single-molecule magnets (SMMs) are promising prototypes that can reach magnetic bistability within the molecular scale required for data storage. Despite the extensive library of versatile ...
This thesis focuses on the search for new methodologies for the direct, stereoselective and catalytic formation of carbon-carbon bonds through the formation of chiral nickel(II) enolate species and the application of such ...
[eng] Nanomedicine is one of the cutting-edge fields in most of medical applications, specially, in oncology. The possibility to selectively vehiculize and specifically release a wide range of anticancer compounds gained ...
The photoactivation of metal complexes with potential anticancer activity is a hot topic of current research, as it may lead to the development of more selective and efficient drugs. Photoactivated chemotherapy (PACT) with ...
Desde hace años la ciencia del magnetismo ha centrado uno de sus objetivos más ambiciosos en el estudio y creación de dispositivos funcionales a escala molecular. Un ejemplo es el intento de implementación de la computación ...
c-Src tyrosine kinase is associated with poor prognosis in many cancer processes. Although inhibitors of c-Src kinase activity are known, they have not reached success in clinical trials because of lack of selectivity or ...
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 ...
