Electrochemical behaviour of conducting polymers obtained into clay-catalyst layers: an in situ Raman spectroscopy study
Boutaleb, Nadia - Benyoucef, Abdelghani - Salavagione, Horacio Javier - Belbachir, Mohammed - Morallón Núñez, Emilia

Formato:	info:eu-repo/semantics/article
Enlaces:	In this paper we present the study of the electrochemical properties of the following conducting polymers: poly(o-anisidine), polyaniline and copolymers of aniline and o-anisidine obtained by a new synthetic method. The polymers are synthesized in free-of-acid conditions, using an activated…

Effect of the glass substrate on the efficiency of the different orders that propagate in a transmission sinusoidal diffraction grating
Neipp López, Cristian - Sheridan, John T. - Márquez Ruiz, Andrés - Gallego Rico, Sergi - Ortuño Sánchez, Manuel - Beléndez Vázquez, Augusto - Pascual Villalobos, Inmaculada

Formato:	info:eu-repo/semantics/article
Enlaces:	In this work we study the effect of the glass substrate on the efficiencies of the different orders that propagate inside a transmission sinusoidal diffraction grating. Holographic optical elements are usually recorded on a photosensitive medium deposited on to a…

Scale corrections for faster evaluation of convergent Fresnel patterns
Mas Candela, David - Espinosa Tomás, Julián - Pérez Rodríguez, Jorge - Illueca Contri, Carlos

Formato:	info:eu-repo/semantics/article
Enlaces:	Numerical calculation of Fresnel patterns through fast Fourier transforms usually requires an extremely large number of samples in order to fulfil the Nyquist sampling condition. In many applications, the cut-off frequency of the system is much below the limit fixed…

Complete algorithm for the calculation light patterns inside the ocular media
Pérez Rodríguez, Jorge - Mas Candela, David - Illueca Contri, Carlos - Miret Marí, Juan José - Vázquez Ferri, Carmen - Hernández Poveda, Consuelo

Formato:	info:eu-repo/semantics/article
Enlaces:	Realistic mathematical models are of great importance for studying the optical performance of the human eye. Light propagation algorithms provide robust methods to calculate field distributions inside a homogeneous medium, and thus they can be applied to the study of…

Newton additive and multiplicative Schwarz iterative methods
Arnal García, Josep - Migallón Gomis, Violeta - Penadés Martínez, José - Szyld, Daniel B.

Formato:	info:eu-repo/semantics/preprint
Enlaces:	Convergence properties are presented for Newton additive and multiplicative Schwarz (AS and MS) iterative methods for the solution of nonlinear systems in several variables. These methods consist of approximate solutions of the linear Newton step using either AS or MS…

Electrochemical regeneration of activated carbon saturated with toluene
García Otón, Miguel - Montilla Jiménez, Francisco - Lillo Ródenas, María Ángeles - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	The electrochemical regeneration of an activated carbon, previously saturated with toluene by gas phase adsorption, was studied. Cathodic and anodic regeneration methods were analyzed using a small batch electrochemical cell. In both cases, a stripping efﬁciency close to 100% was…

Activation and blockade by choline of bovine α7 and α3β4 nicotinic receptors expressed in oocytes
González-Rubio, Juana María - Rojo Ruiz, Jonathan - Tapia López, Laura - Maneu Flores, Victoria - Mulet Soler, José - Valor Becerra, Luis Miguel - Criado Herrero, Manuel - Sala Merchan, Francisco - García García, Antonio - Gandía Juan, Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	Choline, the precursor and the metabolite of acetylcholine, is reputed as a selective α7 nicotinic receptor agonist. In this study, however, we have seen that choline exerted a dual effect on bovine nicotinic receptors expressed in Xenopus oocytes. On the…

Semivolatile and volatile compounds from the pyrolysis and combustion of polyvinyl chloride
Aracil Sáez, Ignacio - Font Montesinos, Rafael - Conesa Ferrer, Juan Antonio

Formato:	info:eu-repo/semantics/article
Enlaces:	Emissions evolved from the pyrolysis and combustion of polyvinyl chloride (PVC) were studied at four different temperatures (500, 700, 850 and 1000 °C) in a horizontal laboratory tubular quartz reactor in order to analyse the influence of both temperature and…

Antropic effect on hydrochemical characteristics of the Valle de Toluca aquifer (central Mexico)
Esteller Alberich, María Vicenta - Andreu Rodes, José Miguel

Formato:	info:eu-repo/semantics/article
Enlaces:	El acuífero del Valle de Toluca, localizado en el Altiplano Mexicano, se encuentra sometido a una intensa explotación para cubrir las necesidades de agua en el propio valle, así como parte de las de Ciudad de México. Los altos niveles…
