Functionalised poly (vinyl alcohol)/graphene oxide as polymer composite electrolyte membranes
2019
[EN] Crosslinked poly(vinyl alcohol) (PVA) based composite films were prepared as polyelectrolyte membranes for low temperature direct ethanol fuel cells (DEFC). The membranes were functionalised by means of the addition of graphene oxide (GO) and sulfonated graphene oxide (SGO) and crosslinked with sulfosuccinic acid (SSA). The chemical structure was corroborated and suitable thermal properties were found. Although the addition of GO and SGO slightly decreased the proton conductivity of the membranes, a significant reduction of the ethanol solution swelling and crossover was encountered, more relevant for those functionalised with SGO. In general, the composite membranes were stable under …
Tras los pasos de Sorolla en Roma:La identificación arqueológica de una crátera griega en su pintura.
2022
El presente estudio analiza una crátera griega de campana realizada con la técnica de figuras rojas que Sorolla representó varias veces durante su estancia de pensionado en Roma. El nivel de detalle con el que este vaso se representa y la metodología pictórica de Sorolla parecen indicar que se trata de una pieza real. La búsqueda del correlato arqueológico, empleando para ello corpora y bases de datos de cerámica, ha permitido saber de qué vaso se trata y en qué colección se encontraba, lo que arroja nuevos datos sobre la estancia y el trabajo de Sorolla en Roma.

A kinetic study of the formation of smectic phases in novel liquid crystal ionogens
2013
[EN] A multi-rate non-isothermal kinetic analysis of the isotropic-melt to liquid crystalline phase transition of novel liquid crystalline ionogenic copolymers, LCIs, the 10-(4-methoxyazobenzene-4'-oxy)decyl methacrylate]-co-2-(acrylamido-2-methyl-1-propanesulfonic acid)s, 10-MeOAzB/AMPS, copolymers, has been performed by means of calorimetric experiments. An analytical methodology which includes the study of the phase transition rate parameter, the determination of the activation energies by using Kissinger and Flynn-Wall-Ozawa models, and the study of the phase transition kinetics by the use of the Avrami theory, has been applied. The formation of the mesophases from the isotropic state o…
Toros y Cultura. Una aproximación a la ordenación jurídica de los espectáculos taurinos en España desde el Derecho público
2023
La tauromaquia constituye actualmente, en determinados espacios geográficos, una realidad cultural, que trasciende a múltiples espacios y sectores, también al ámbito jurídico. Arraigada en la costumbre y en la vida social de esos territorios desde siglos atrás, especialmente en España, como destacara el filósofo José Ortega y Gasset, este hecho no ha sido óbice para que las fiestas de toros, sobre las que se funda, hayan sido epicentro de atención de diferentes personalidades a lo largo de la historia, también de los poderes públicos. Inicialmente, bajo el pretexto de la peligrosidad que comportaba la lidia de reses bravas y, recientemente, sobre postulados simplemente animalistas, estos úl…
Electrochemical Synthesis of an Organic Thermoelectric Power Generator.
2020
[EN] Energy harvesting through residual heat is considered one of the most promising ways to power wearable devices. In this work, thermoelectric textiles were prepared by coating the fabrics, first with multiple-wall carbon nanotubes (MWCNTs) by using the layer-by-layer technique and second with poly(3,4-ethylenedioxythiophene) (PEDOT) deposited by electrochemical polymerization. Sodium deoxycholate and poly(diallyldimethylammonium chloride) were used as stabilizers to prepare the aqueous dispersions of MWCNTs. The electrochemical deposition of PEDOT on the MWCNT-coated fabric was carried out in a three-electrode electrochemical cell. The polymerization of PEDOT on the fabric increased the…

Tailored electrospun nanofibrous polycaprolactone/gelatin scaffolds into an acid hydrolytic solvent system
2018
[EN] Blended nanofibrous scaffolds based on polycaprolactone (PCL) and gelatin (Ge) were successfully prepared. A formic/acetic acid (1:1) mixture was used to dissolve PCL/Ge blends from 100/0 to 20/80 %wt in steps of 10 %wt. The hydrolysis of the PCL diluted in the formic/acetic acid mixture was considered as a method for tailoring the surface morphology and physicochemical features of the nanofibrous PCL/Ge scaffolds as a function of the dissolution time. The fibre diameter remained in the nanoscale range for all the studied scaffolds, which is crucial to mimic the extra-cellular matrix size. The reduction of the intrinsic viscosity, molar mass and hydrodynamic radius found for the PCL mo…
Juan Luis Vives ante la Fortuna
2011
En el presente artículo se analiza la significación ética y política de los conceptos de fortuna y providencia en Juan Luis Vives. A través de ellos se materializan dos antropologías distintas encarnadas respectivamente en N. Maquiavelo y el propio J.L. Vives. Un punto de cruce entre ambas visiones de la realidad es el Lazarillo de Tormes en el que una fortuna dominada por el esfuerzo deriva en un éxito que no es más que una indignidad moral. En Vives la actitud razonable no es vivir dominando la fortuna, sino vivir por encima de la fortuna. Es en ese punto donde emerge la providencia como el cuidado amoroso que conduce al ser humano al conócete a ti mismo. In the present paper we analyze t…
Encapsulation of Vitamins A and E as Spray-Dried Additives for the Feed Industry
