En la presente memoria, se aborda el estudio de la resistencia a la corrosion en distintos medios, de acero inoxidables austeniticos a los que se le ha variado o la composicion o el proceso de obtencion, respecto a los aceros clasicos obtenidos por colada y laminacion. El comportamiento de estos nuevos materiales se h…
La principal caracteristica de la produccion de pasta mecanica es el aprovechamiento de la materia prima. Los procesos de preparacion de estas pastas empleando soluciones de H2O2 en medio alcalino permiten obtener pastas APRM de buena calidad y empleando para ello bajos consumos energeticos. Uno de los principales pro…
Abstract This chapter provides a brief summary of the available synthetic methods leading to poly(p‐phenylene vinylene)s (PPVs), followed by a detailed discussion of the mechanism of PPV synthesis, employing the Gilch route. In the latter case,in situ‐generatedp‐quinodimethanes are shown to be the active monomers. Spo…
Se ha estudiado la obtencion selectiva de p-xileno a partir de la reaccion de alquilacion de tolueno con metanol, utilizando catalizadores de zeolita zsm-5 modificados. Los experimentos se realizaron en una instalacion constituida por un reactor de lecho fijo y provista de un adecuado sistema para la medida y control…

The carrier density in tens of nanometers thick graphite samples (multi-layer-graphene, MLG) has been modified by applying a gate voltage ($V_g$) perpendicular to the graphene planes. Surface potential microscopy shows inhomogeneities in the carrier density ($n$) in the sample near surface region and under different v…

Pt-based bimetallic nanoparticles have attracted significant attention as a promising replacement for expensive Pt nanoparticles. In the systematic design of bimetallic nanoparticles, it is important to understand their preferred atomic structures. However, compared with unary systems, alloy nanoparticles present more…
La presente tesis doctoral aborda la posible incidencia que determinados medios factibles de encontrarse en una estructura de hormigon armado, como son el medio neutro con hco3- y el alcalino con so4=, pueden ejercer en un fallo por corrosion bajo tension (cbt), fenomeno al que el acero de pre o postensado ha resultad…

Very recently, it has been shown that an abundant material, polymeric carbon nitride, can produce hydrogen from water under visible-light irradiation in the presence of a sacrificial donor [1]. We will present here the preparation and characterization of graphitic carbon nitride (g-C3N4) films on semiconducting substr…
