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 blood-brain barrier (888) is a biological barrier that plays a crucial role protecting the brain from neurotoxic agents and regulating the influx and efflux of molecules required for the correct function of this organ. ...
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] Intrinsically disordered proteins (IDPs) landed on the molecular biology framework at the turn of the 20th century to challenge the established protein function- structure paradigm. Due to their inherent flexibility ...
[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 ...
Durant les dècades dels anys 50 i 60 del segle XX es van utilitzar arreu del món diferents tipus de compostos organoclorats i organobromats, que pertanyen als contaminants orgànics persistents (COPs), com a pesticides, ...
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 ...
Pain is one of the main medical problems that in several cases results into a chronic disease with limited effective treatment, thus the discovery of new drugs to fight against constitutes a big challenge nowadays. Metabotropic ...
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 ...
[spa] La presente Tesis de carácter multidisciplinar se centra en el diseño y síntesis de nuevos derivados de C75 como potenciales agentes antitumorales e inhibidores de la ingesta para el desarrollo de nuevos fármacos ...
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 ...
[eng] In this doctoral thesis, the design and synthesis of bifunctional molecules that induce the degradation of a target protein in cells are described. The synthesis of molecules capable of inducing the phosphorylation ...
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] Protein-protein interactions (PPIs) play a crucial role in the homeostasis of the cells; therefore, they are important therapeutic targets. Typically, the goal in targeting PPIs is to impede them. On the contrary, ...
