New Gold(I) Alkynophylic Catalysts<br/><br/>Autor: Mihai Raducan<br/>Director: Antonio M. Echavarren<br/>Resumen para TESEO en castellano:<br/><br/> El uso de nitrilos aromáticos ricos en electrones permitió el aislamiento ...
New gold-catalyzed reactions and applications for the synthesis of alkaloids
En esta Tesis Doctoral se realiza un estudio detallado de la reacción inter- e intramolecular de compuestos carbonílicos con 1,6-eninos catalizada por complejos de oro(I), racionalizando las variables que permiten la ...
A new grey area mitigation technique for DES : theory and assessment
The use of hybrid RANS-LES methods has become widespread during the last decade, as an interesting approach for covering the gap between RANS and LES turbulence models in terms of both computational resources and degree ...
New Heuristics for Planning with Action Costs
Classical planning is the problem of nding a sequence of actions that take an agent from an initial state to a desired goal situation, assuming deter- ministic outcomes for actions and perfect information. Satis cing ...
New Horizons in Computational Modeling of Polyoxometalates: Biological Activity, Energy Storage and Sustainable Catalysis
Els Polioxometal·lats (POMs) constitueixen una família d’òxids metàl·lics moleculars normalment formats per W, Mo o V en l’estat d’oxidació més elevat. Degut a les seves característiques moleculars i electròniques, els ...
New hybrid materials based on metal-organic frameworks for the removal of organic pollutants
[eng] The growing awareness of the negative effects that industrial and human activities have on the environment and public health and, more specifically, on water resources, has led to the development of new strategies ...
New Immobilized Catalytic Systems for Batch and Flow Applications
Durant el transcurs de la Tesi, s’ha desenvolupat un sistema catalític per reaccions aldòliques altament estereoselectives en flux continu basats en una prolina immobilitzada en una resina de ...
New immunochemical approaches for Multiplexed diagnostics
The central topic of this thesis has been the study, development and validation of diverse multiplexed diagnostics platforms and techniques that can be applied to a wide range of topics, from environmental monitoring to ...
New insights about the role of WT1 in blood vessel formation during development and repair
The pleiotropic WT1 transcription factor (WT1) was first discovered in renal tumours. It contains four zinc-finger motifs at the C-terminus which are important for DNA binding to activate gene expression and is also involved ...
New insights in photodynamic theraphy: production, diffusion and reactivity of singlet oxygen in biological systems
S'ha estudiat la cinètica de fotosensibilització de l'oxigen singlet (1O2) en cèl·lules eucariotes en suspensió mitjançant un espectròmetre d'última generació amb resolució temporal per sota del microsegon. Els estudis ...
New insights in the epigenetic control of EMT
The epithelial to mesenchymal transition (EMT) is a highly conserved cellular program that allows well-‐differentiated epithelial cells to convert to motile mesenchymal cells. EMT is critical f ...
New insights in the study and characterization of fungal metallothioneins and their relationship with the pathogenic activity
Las metalotioneínas (MTs) constituyen una superfamilia de metaloproteínas de bajo peso molecular caracterizada por un contenido extraordinario de cisteína, que les proporciona la capacidad de coordinar iones de metales ...
New insights in vulcanization chemistry using microwaves as heating source
La vulcanització per microones és un procés madur i no hi ha dubte sobre la seva eficiència per produir articles de cautxú d'alta qualitat. Les microones són conegudes no només per la seva capacitat d'accelerar els processos ...
New insights into alzheimer’s disease: further characterization of the 3xTg-AD mouse model and a pharmacological approach with scFv-h3D6
La malaltia d’Alzheimer és el desordre neurodegeneratiu més comú arreu del món. L’acumulació del pèptid beta-amiloide (Aβ) és el principal factor en el seu patomecanisme. El model murí 3xTg-AD ha esdevingut un dels models ...
New insights into boar sperm function and survival from integrated field and laboratory studies
En aquesta tesi s'han dut a terme dos tipus d'estudis diferents. L'objectiu del primer era la preservació del semen de porcí a 15ºC i el del segon eren els co-cultius homòlegs de cèl·lules epitelials de l'oviducte i ...
New insights into carotenoid accumulation in tomato fruit = Nuevos aspectos sobre acumulación de carotenoides en el fruto del tomate
Lycopene is an antioxidant carotenoid present in high amounts inside the ripe tomato fruit, in watermelon, red bell pepper and a few other red-pigmented fruits. Its health benefits, notably the prevention of prostate cancer ...
New insights into Cr electrodeposits obtained from Cr(III)-based electrolytes: effect of the chemistry and semiconducting properties of their oxide films on the corrosion behaviour
Esta tesis se centra en el estudio de diferentes recubrimientos/electrodepósitos de Cr obtenidos a partir de baños modelo de Cr(III) (basados en cloruros y sulfatos). Además, se utilizaron como sistema de referencia ...
New insights into holography from supersymmetric localization
Maldacena's conjecture, often known as the holographic duality or the AdS/CFT correspondence, proposes an equivalence between gravitational theories in a hyperbolic space of a certain dimensionality and gauge theories ...
