Searching suitable panchromatic QD sensitizers for expanding the light-harvesting range, accelerating charge separation, and retarding charge recombination is an effective way to improve power conversion efficiency (PCE) of quantum-dot-sensitized solar cells (QDSCs). One possible way to obtain a wide absorption range is to use the exciplex state of a type-II core/shell-structured QDs. In addition, this system could also provide a fast charge separation and low charge-recombination rate. Herein, we report on using a CdTe/CdSe type-II core/shell QD sensitizer with an absorption range extending into the infrared region because of its exciplex state, which is covalently linked to TiO2 mesoporous electrodes by dropping a bifunctional linker molecule mercaptopropionic acid (MPA)-capped QD aqueous solution onto the film electrode. High loading and a uniform distribution of QD sensitizer throughout the film electrode thickness have been confirmed by energy dispersive X-ray (EDX) elemental mapping. The accelerated electron injection and retarded charge-recombination pathway in the built CdTe/CdSe QD cells in comparison with reference CdSe QD-based cells have been confirmed by impedance spectroscopy, fluorescence decay, and intensity-modulated photocurrent/photovoltage spectroscopy (IMPS/IMVS) analysis. With the combination of the high QD loading and intrinsically superior optoelectronic properties of type-II core/shell QD (wide absorption range, fast charge separation, and slow charge recombination), the resulting CdTe/CdSe QD-based regenerative sandwich solar cells exhibit a record PCE of 6.76% (J(sc) = 19.59 mA cm(-2), V(oc) = 0.606 V, and FF = 0.569) with a mask around the active film under a full 1 sun illumination (simulated AM 1.5), which is the highest reported to date for liquid-junction QDSCs.

Treball Final de Grau. Grau en Psicologia. Codi: PS1048. Curs acadèmic 2016/2017 El alcohol es la droga más aceptada y consumida en el mundo, la cual puede causarte un alto nivel de dependencia, a causa, principalmente, del efecto reforzante que produce en tu cerebro. En el presente trabajo nos vamos a centrar en la importancia que tiene el salsolinol en nuestro organismo tras el consumo de alcohol, así pues, el objetivo es aceptar o refutar la siguiente hipótesis: Un producto de la condensación de acetaldehído y dopamina es el responsable del efecto reforzante del etanol. Es decir, el salsolinol, como producto derivado de la condensación no enzimática de acetaldehído y dopamina, es el responsable del reforzamiento positivo. Aparece tras el consumo de etanol, y gracias a la metabolización de este. Todavía no se sabe el mecanismo de acción del salsolinol, pero sabemos que juega un papel importante a la hora de crear dependencia, llegando a pensar que el alcohol actúa como una prodroga. El salsolinol es una molécula reforzante, más potente que el acetaldehído y el etanol. The alcohol is the drug most accepted and consumed in the world, which can cause a high level of dependence, to reason, principally, of the reinforcing effect that produces in your brain. In the present work, we us go to focus in the importance that salsolinol has in our organism after consume alcohol, this way so, the objective is to agree or to refuse the following hypothesis: A product of the condensation of acetaldehyde and dopamine is the responsible of the effect positive reinforcement of the ethanol. The salsolinol, as product derived from the non-enzymatically condenses of acetaldehyde and dopamine, is the responsible of the positive reinforcement. It appears after consume ethanol, and thanks to metabolizing of this one. The mechanism of action of the salsolinol is not yet known, but we know that it plays an important role in creating dependency, coming to think that alcohol acts as a prodrug. The salsolinol more reforcing molecule that acetaldehyde and ethanol.

Peroxisome Proliferator-Activated Receptors (PPARs) and its co-activators are regulatory elements of the cellular lipid homeostasis and have been associated with feeding behavior modulation. Animal models suggest that these genes may be involved in alcohol consumption regulation. However, no studies in humans exist. Our aim is to estimate the possible association between polymorphisms in the PPAR-alpha, PPAR-gamma and PPAR-gamma co-activator 1A (PGC-1A) genes and alcohol consumption in humans.We have conducted a cross-sectional study between the PPAR-alpha L162V, PPAR-gamma P12A and PGC-1A G482S polymorphisms, and alcohol consumption in a general Mediterranean Spanish population (303 men and 443 women).We have found an association between the L162V polymorphism and alcohol consumption in which, carriers of the V allele were more prevalent among alcohol consumers (19.4% vs. 9.8%; OR 2.69; 95% CI: 1.31-5.54, p=0.007). The G482S polymorphism showed a significantly higher frequency in the group of high alcohol drinkers than in non-high alcohol drinkers (33.4% vs. 20.6%; OR 2.28; 95% CI: 1.07-4.88, p=0.034). Mean alcohol consumption was higher as the number of G alleles increased (GG 8.6+/-12.8 g/day, GS 6.6+/-9.2 g/day, SS 5.6+/-7.8 g/day, p=0.003). These results remained statistically significant after covariate adjustment.PPAR-alpha L162V and PGC-1A G482S polymorphisms are associated with alcohol consumption in the Mediterranean population.

Treball Final de Màster Universitari en Estudis Internacionals de Pau, Conflictes i Desenvolupament (Pla de 2013). Codi: SBG120. Curs acadèmic: 2016/2017 The Earth’s resources are limited and it is important that we conserve as much as possible. One way to do this is to recycle waste products. The main objective of this project is to decrease the amount of recyclable garbage that is not being recycled in the city of Castellón de la Plana. With the high number of plastic and glass bottles that are being used in restaurants, pubs, and family homes, a vast majority of these will likely be thrown in the garbage instead of recycling. Although there are a number of areas that allow easy access for recycling, the convenience of tossing something into the garbage is considered more convenient. This project will attempt to look at various options to not only provide enticement for businesses to recycle, but also potentially allow a form of income as an incentive.

The main system of central ethanol oxidation is mediated by the enzyme catalase. By reacting with H2O2, brain catalase forms compound I (the catalase–H2O2 system), which is able to oxidize ethanol to acetaldehyde in the brain. Previous studies have demonstrated that pharmacological manipulations of brain catalase activity modulate the stimulant effects of ethanol in mice. However, the role of H2O2 in the behavioral effects of ethanol has not yet been clearly addressed. In the present study, we investigated the effects of alpha-lipoic acid (LA), a scavenging agent for H2O2, on ethanol-induced locomotor stimulation. CD-1 mice were pretreated with LA [0–100 mg/kg, intraperitoneally (IP)] 0–60 min prior to administration of ethanol (0–3.75 g/kg, IP). In another experiment, animals were pretreated with LA (0, 25, or 50 mg/kg, IP) 30 min before cocaine (10 mg/kg, IP), amphetamine (2 mg/kg, IP), or caffeine (25 mg/kg, IP). After these treatments the animals were placed in an open-field chamber and their locomotor activity was measured for 20 min. LA 25, 50, and 100 mg/kg IP prevented ethanol-induced locomotor stimulation. LA did not affect the locomotor-stimulating effects of cocaine, amphetamine, and caffeine. Additionally, we demonstrated that LA prevents the inactivation of brain catalase by 3-amino-1,2,4-triazole, thus indicating that H2O2 levels are reduced by LA. These data support the idea that a decrease in cerebral H2O2 production by LA administration inhibits ethanol-stimulated locomotion. This study suggests that the brain catalase–H2O2 system, and by implication centrally formed acetaldehyde, plays a key role in the psychopharmacological effects of ethanol.

Treball Final de Grau en Finances i Comptabilitat. Codi: FC1049. Curs acadèmic: 2019/2020 In recent years there has been a rise in businesses investing in social and ethical issues. The sustainable development goals published in 2015 by the UN provide a globally agreed framework to make the world more sustainable. Companies have been given the opportunity to help the environment and society through their actions whilst increasing their value and return and improving their reputation. A method for doing so is by following the principles of responsible investment and incorporating environmental, social and governance criteria into long-term businesses strategies. Spanish banks are actively working to achieve the sustainable development goals by investing in sustainable finance, social projects, housing programmes, etc. to meet societal needs whilst extending their market scope and achieving corporate growth and financial success. The main focus of their actions lays with two specific goals: ending poverty and providing decent work and economic growth for all.

Treball Final de Grau en Psicologia. Codi: PS1048. Cursacadèmic 2013-2014 Currently, alcohol is one of the most consumed drugs worldwide. However, despite all the advances in neuroscience, mechanism of action of alcohol at a central level is still unknown. The main objective of this work is proposing and testing a hypothesis about how alcohol works in the brain, based on the idea of its operation on intracellular calcium and different mediators of cAMP-PKA cascade. The method of this paper consists of the analysis of 4 studies that show the manipulations of the different mediators of calcium and cAMP-PKA and the consequences of these manipulations at a molecular, cellular, neurobiological and behavioural level. The results show that, possibly, these mediators of calcium are very important in explaining the mechanism of action of alcohol on the brain. However, it cannot be assumed the exact mechanism by which alcohol acts at a central level. Actualmente, el alcohol es una de las drogas más consumidas a nivel mundial. Sin embargo, a pesar de todos los avances de la neurociencia, el mecanismo de acción del alcohol a nivel central aún es desconocido. El objetivo principal de este trabajo es tratar de plantear y probar una hipótesis de cómo funciona el alcohol en el cerebro, partiendo de la idea de su funcionamiento sobre el calcio intracelular y diferentes mediadores de la cascada AMPc-PKA. El método de este trabajo consta del análisis de 4 estudios que muestran las manipulaciones de diferentes mediadores de calcio y AMPc-PKA y las consecuencias de esas manipulaciones a nivel molecular, celular, neurobiológico y conductual. Los resultados nos muestran que, posiblemente, estos mediadores de calcio sean muy importantes a la hora de explicar el mecanismo de acción del alcohol en el cerebro. Sin embargo, aún no se puede afirmar con certeza claridad el mecanismo exacto por el que el alcohol actúa a nivel central.

Curs: 2017/2018 The present study aims to analyse the effects of the growth experienced by the Spanish photovoltaic sector in mid-2007, and the subsequent crisis which began at the end of 2008. In the first part of this paper the historical evolution of solar energy across the globe, its appearance and development at national level, the current situation in relation to solar energy in different countries and continents, and the evolution of the sector in recent years will be explained. Subsequently, we shall proceed to carry out an empirical analysis in order to determine the aggregate effect of the measure which constituted the driving force in the sector (RD661/2007) and of the measure responsible for the decline (RD 1578/2008) through the study of the levels of performance and risk of a sample of companies dedicated to the distribution and installation of photovoltaic material, before and after experiencing the combined effect of the two measures. It may be concluded that, in general, the companies remained in a similar situation, in terms of both profitability and of risk, except with regard to the ratio which measures the solvency of the company in the short term, which presents significant differences between the two years considered.
