Surface modifications of EVA copolymers induced by low pressure RF plasmas from different gases and their relation to adhesion properties
Cepeda Jiménez, Carmen María - Torregrosa Maciá, Rosa - Martín Martínez, José Miguel

Formato:	info:eu-repo/semantics/article
Enlaces:	Two ethylene vinyl acetate (EVA) copolymers (12 and 20 wt% of vinyl acetate,VA, content) have been treated with low pressure RF plasmas from non-oxidizing gases (Ar, N2) and oxidizing gases (air, a mixture of 4N2: 6O2 (v/v), O2 and CO2).…

Chemical modification of styrene –butadiene –styrene (SBS) rubber by reactive grafting with maleic anhydride
Lasalle, Verónica Leticia - Failla, Marcelo Daniel - Vallés, Enrique Marcelo - Cepeda Jiménez, Carmen María - Torregrosa Maciá, Rosa - Martín Martínez, José Miguel

Formato:	info:eu-repo/semantics/article
Enlaces:	A procedure to increase the adhesion of block styrene–butadiene–styrene (SBS) rubber consisting of the reactive grafting with maleic anhydride (MA) in the presence of an organic peroxide radical initiator is proposed. The influence of the reactive grafting on the surface…

Genetic relationships among some species groups within the genus Lutzomyia (Diptera: Psychodidae)
Torgerson, Dara G. - Lampo, Margarita - Velásquez Zambrano, Yelitza - Woo, Patrick T.K.

Formato:	info:eu-repo/semantics/article
Enlaces:	Molecular data on Lutzomyia are very scarce, despite the fact that this genus includes all the species involved in the transmission of leishmaniasis in America. We examine the genetic relationships among eight morphologic groups within the Lutzomyia genus and two…

Evaluation of the electrocatalytic activity of antimony-doped tin dioxide anodes toward the oxidation of phenol in aqueous solutions
Montilla Jiménez, Francisco - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	Antimony-doped tin dioxide electrodes supported on titanium have been used in the electrochemical treatment of aqueous solution containing phenol. Ti/SnO2–Sb anode has high efficiency in the elimination of phenol, but its use is hindered by its short service life. The…

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…

Near-field light distributions propagated from human corneas: determination of relevant patterns
Mas Candela, David - Pérez Rodríguez, Jorge - Vázquez Ferri, Carmen - Hernández Poveda, Consuelo - Illueca Contri, Carlos

Formato:	info:eu-repo/semantics/article
Enlaces:	A procedure to determine the best image range of distances that can be obtained from an aphakic eye is presented. Corneal surfaces are calculated from videokeratographic data. Light distributions at different distances inside the eye are calculated with a near-field…

Stabilization of volume gratings recorded in polyvinyl alcohol-acrylamide photopolymers with diffraction efficiencies higher than 90%
Gallego Rico, Sergi - Neipp López, Cristian - Ortuño Sánchez, Manuel - Beléndez Vázquez, Augusto - Pascual Villalobos, Inmaculada

Formato:	info:eu-repo/semantics/article
Enlaces:	Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…
