Estudio de degradación acelerada de catalizadores para celdas de combustible de metanol
(Investigación Joven, 2016)
Catalizadores trimetálicos PtMRu/C (M= Co, Fe) tolerantes a la presencia de metanol fueron caracterizados por medio de HRTEM, EDS, XPS y electroquímicamente mediante curvas de polarización y voltamperometría cíclica. Para ...
On the strategies for incorporating nanosilica aqueous dispersion in the synthesis of waterborne polyurethane silica nanocomposites, Effects on morphology and properties
(2016)
In this work the synthesis of waterborne polyurethane/nanosilica nanocomposites by using two differ- ent strategies is presented, starting from a vinyl terminated polyurethane prepolymer (PUP) based on isophorone diisocyanate ...
Interfase hormigón asfalto con interposición de geosintético, en la restauración de pavimentos
(Mattear, 2016-10-13)
Generalmente un pavimento de hormigón deteriorado se restaura mediante una capa de refuerzo asfáltico. Actualmente, una intervención adecuada consiste en interponer un material geosintético para retardar el reflejo de ...
Structure of force networks in tapped particulate systems of disks and pentagons I Clusters and loops
(American Physical Society, 2016)
The force network of a granular assembly, defined by the contact network and the corresponding contact
forces, carries valuable information about the state of the packing. Simple analysis of these networks based on the ...
Influence of dynamic crosslinking on the morphology, crystallization, and dynamic mechanical properties of PA6,12 EVA blends
(2016)
This study investigated the effect of dynamic crosslinking of polyamide 6,12 and random copolymers of ethylene and vinyl
acetate blends (PA6,12/EVA) on the morphology, crystallinity, and dynamic mechanical properties. The ...

Chitosan-graft-poly(n-butyl acrylate) copolymer Synthesis and characterization of a natural synthetic hybrid material
(2016)
Two chitosan polymers with different deacetylation degree and molecular weight were subjected to graft- ing reactions with the aim to enhance the properties of these bio-based materials. Specifically, n-butyl acrylate in ...
Biodegradation and biodeterioration of wooden Heritage, role of fungal succession
(International Journal of Conservation Science, 2016)
Wood from heritage is usually attacked by wood-decay fungi generating mainly loss of dimensional and structural stability. The study of wood biodegradation process and its mechanism allow the obtaining of tools for wood ...
Nickel oxide performance as anode material for lithium ion batteries
(IWLiME, 2016-11-01)
Lithium ion batteries, as a rechargeable power source, have attracted much more attention due to their extensive applications in portable electronic devices and electric vehicles. Although most commercial Li-ion batteries ...
