This PhD thesis has been developed in the Molecular Magnetism Group of the University of Barcelona. As its name indicates, the Molecular Magnetism Group is mostly interested in the magnetic study of coordination complexes, ...
La abrazadera deslizante eucariota (PCNA), juega un papel esencial como componente del replisoma. PCNA, de forma toroidal, rodea el DNA y ata las polimerasas y otros factores a la plantilla genómica para una síntesis ...
Nanoparticles are highly relevant for catalysis due to their nanostructure, which increases the fraction of surface atoms, and the size dependent morphology and properties. Catalytic properties of nanoalloys also depend ...
Organic/inorganic interfaces play a key role in organic electronic devices such as organic light emitting diodes (OLED), organic field effect transistors (OFET) and organic solar cells (OSC). In these interfaces crucial ...
En la presente tesis doctoral se desarrollaron métodos analíticos para la determinación de fármacos de uso humanos en el tejido muscular de los peces, incluyendo la comparación y optimización de diferentes tipos de ...
This Thesis deals with the resolution of hyperspectral imaging data by using chemometric methods, in particular by using appropriate data pretreatment methods and by using Multivariate Curve Resolution (MCR) methods. The ...
In recent decades, global plastics production and consumption have continued to increase. Although many policy strategies on waste prevention and recycling have been implemented, much of the plastic waste is dispersed in ...
The main subject of this Thesis is the production of hard, wear and corrosion resistant cermets tungsten carbide and cobalt cermets (WC-Co) with different contents in cobalt matrix, onto low carbon steels and aluminum alloy ...
Catalysis is ubiquitous in chemical industries since it accelerates chemical reactions, thereby saving considerable amounts of energy. Most catalytic processes in industry are heterogeneous in nature, typically involving ...
The work carried out in this thesis is based on the study of transition metal carbides (TMCs) as catalysts study from a theoretical point of view, using the techniques of Computational Chemistry. TMC materials have been ...
[eng] Computational simulation technologies facilitate the resolution of complex biomedical problems by helping researchers predict what will happen in a natural system in response to various external conditions. The main ...
Carbohydrates were early considered important for energy storage and structural support for living organisms. It was not until a few decades ago that scientist discovered that they are also involved in much more complex ...
The principal aim of this thesis is the understanding of the electronic structure of organic diradical and polyradical molecules. Unveiling the properties that give them the electronic, magnetic, and optical properties to ...
For many years symmetry has been a useful concept in the study of the spatial organization of atoms in molecules or solids. The presence of symmetry elements in a given molecular structure gives a valuable information about ...
This thesis is a multidisciplinary study of the solid state of squaric acid derivatives which combines approaches from areas such as crystal engineering, supramolecular chemistry and crystallography. The structural preferences ...
The main objective of this research work was to produce environmentally friendly cermets coatings, Ni and Co free matrix, alternative to conventional WC- Co, by thermal spray processes. WC-Co cermets has always been one ...
Se han obtenido distintas aleaciones policristalinas de base cobre así como monocristalinas de ZuCnAlCo, las cuales han sido caracterizadas quimícamente, estructural y calorimétricamente. Se ha utilizado un nuevo método ...
En aquesta Tesi s’han estudiat les fonts d’emissió de diversos contaminants atmosfèrics, principalment a l’àrea de Barcelona. Els contaminants estudiats han estat l’òxid de nitrogen (NO), compost tòxic que s’emet en grans ...
The general objective of this research was the design of polymeric cationic nanoparticles from nano-emulsions obtained by low-energy methods for biomedical applications. This general objective includes the preparation of ...
[eng] The main objective of this dissertation has been to stablish a bridge between materials science and its fields of application. The scope of this thesis work, under this premise, is aimed towards understanding the ...
