Toca-Toca: ejemplos sencillos para conceptos complejos en asignaturas de ciencia y tecnología de materiales
(Sociedad Española de Materiales SOCIEMAT, 2017)
En las asignaturas de tipo “Fundamentos de Ciencia de los Materiales” es habitual encontrar que la propuesta de temario es muy extensa y que en ella se introducen un gran número de conceptos, que van desde las bases ...
Effect of the Purification Treatment on the Valorization of Natural Cellulosic Residues as Fillers in PHB-Based Composites for Short Shelf Life Applications
(Springer, 2021)
In this work the effect of a combined NaOH + peracetic acid (PAA) purification treatment on the valorization of almond shell (AS) and rice husk (RH) lignocellulosic residues as fillers in PHB-based composites for short ...
On the use of tris(nonylphenyl) phosphite as a chain extender in melt-blended poly(hydroxybutyrate-co-hydroxyvalerate)/clay nanocomposites: Morphology, thermal stability, and mechanical properties
(© 2015 Wiley Periodicals, Inc., 2015-06)
The influence of the incorporation of tris(nonylphenyl) phosphite (TNPP) as a chain extender on the morphology and thermal stability of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV)/clay nanocomposites obtained by melt ...
Modification of Nafion Membranes with Polyaniline to Reduce Methanol Permeability
(Electrochemical Society, 2015)
The modification of Nafion membranes with polyaniline (PAni) has been studied as an alternative for reducing methanol crossover in direct methanol fuel cells (DMFC). The modification has been performed by directly polymerizing ...
Void Content Minimization in Vacuum Infusion (VI) via Effective Degassing
(Multidisciplinary Digital Publishing Institute, 2021-09-01)
This paper addresses the major concern which component porosity represents in Vacuum
