13 p, 14.7 MB Exploring traffic evaporation : Findings from tactical urbanism interventions in Barcelona / Nello-Deakin, Samuel (Universitat Autònoma de Barcelona. Departament de Geografia)
Traffic evaporation - i. e. the opposite of induced traffic - is acknowledged as a well-established phenomenon which presents important implications for local urbanism and mobility policies, but there continue to be few academic studies which explore this issue in detail. [...]

12 p, 4.7 MB Enhancement of the supercapacitive properties of laser deposited graphene-based electrodes through carbon nanotube loading and nitrogen doping / Pérez del Pino, Ángel (Institut de Ciència de Materials de Barcelona) ; Rodríguez López, Marta (Institut de Ciència de Materials de Barcelona) ; Ramadan, Mohamed Ahmed (Helwan University) ; García Lebière, Pablo (Institut de Ciència de Materials de Barcelona) ; Logofatu, Constantin (National Institute for Materials Physics) ; Martínez-Rovira, Immaculada (ALBA Laboratori de Llum de Sincrotró) ; Yousef, Ibraheem (ALBA Laboratori de Llum de Sincrotró) ; Gyorgy, Eniko (Institut de Ciència de Materials de Barcelona)
Several technological routes are being investigated for improving the energy storage capability and power delivery of electrochemical capacitors. In this work, ternary hybrid electrodes composed of conducting graphene/reduced graphene oxide (rGO), which store charge mainly through electric double-layer mechanisms, covered by NiO nanostructures, for adding pseudocapacitance, were fabricated through a matrix assisted pulsed laser evaporation technique.

Das Institut für Werkstoffforschung) ; Maria Pilo, Maria (Università degli Studi di Sassari. Dipartimento di Chimica e Farmacia)
We evaluate the influence of the use of different titania precursors, calcination rate, and ligand addition on the morphology, texture and phase content of synthesized mesoporous titania samples, parameters which, in turn, can play a key role in titania photocatalytic performances. [...]

11 p, 748.9 KB Estimating paleogeographic, hydrological and climatic conditions in the upper Burdigalian Vallès-Penedès basin (Catalunya, Spain) / Bitzer, K. (Universität Bayreuth. Abteilung Geologie)
During the evolution of the Vallès-Penedès basin, several transgressive pulses in the upper Burdigalian led to a partial flooding of the western part of the basin, leaving locally sabkha-salina evaporite sediments in the area of the village of Vilobí. [...]

15 p, 201.5 KB Effects of the intense summer desiccation and the autumn filling on the water chemistry in some Mediterranean ponds / Fernández-Aláez, Margarita (Universidad de León. Departamento de Biodiversidad y Gestión Ambiental) ; Fernández-Aláez, Camino (Universidad de León. Departamento de Biodiversidad y Gestión Ambiental)
The objective of this research was to compare the effects of evaporation and total desiccation, as well as the infiuence of the rate of refilling, on the concentrations of major ions and nutrients (nitrogen and phosphorus) in Mediterranean ponds. [...]
El objetivo de este estudio ha sido comparar los efectos de la evaporación y la desecación completa, así como de la tasa de llenado sobre las concentraciones de los principales iones y nutrientes (nitrógeno y fósforo) en un conjunto de lagunas mediterráneas. [...]

40 p, 1.6 MB Pilas biodegradables como fuentes de energía portátiles y desechables / García Pérez, Derek ; Esquivel, Juan Pablo, dir. ; Sabaté Vizcarra, Neus, dir. ; Universitat Autònoma de Barcelona. Facultat de Ciències
En els últims anys, l'augment de l'ús d'aparells elèctrics ha comportat l'augment de la quantitat de residus generats portant a una creixent contaminació a nivell mundial. L'energia química emmagatzemada depèn dels reactius redox usats, que en la majoria de piles actuals es basen en les reaccions de reducció-oxidació de metalls pesants difícils de eliminiar o recuperar. [...]

In recent years, the use of electrical appliances has increased and that has led to an increase in the amount of waste generated, leading to increasing pollution worldwide. The stored chemical energy depends on the redox reagents used, which in most current batteries are based on the heavy metal reduction-oxidation reactions difficult to eliminate or recover. [...]
