Electrochemical characterization of nickel hydroxide nanomaterials as electrodes for NiMH batteries
(Springer, 2016-08-23)
β-Nickel hydroxide was successfully synthesized by a hydrothermal method. Nano-nickel hydroxide material was characterized by X-ray diffraction, infrared absorption spectroscopy, and transmission electron microscopy. They ...
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 ...
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 ...
Morphology and properties of neutralized chitosan-cellulosenanocrystals biocomposite films
(2016)
Chitosan/cellulose nanocrystals (CH-CN) films were obtained by casting of dispersions, and treated with NaOH for neutralization proposes. The composition of films was varied from 1 to 10 wt.% of CN. Changes in the morphology ...
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 ...
Starch Polyvinyl Alcohol blends containing Polyurethane as plasticizer
(2016)
Starch-based films containing 70wt% of starch and a combination of poly(vinyl alcohol) and a low glass transition temperature polyurethane as plasticizer were prepared. The effect of PVA/PU ratio content on the morphology ...
Effect of water content in the gas diffusion layer of H2 O2 PEM fuel cell
(Journal of Materials Science and Engineering, 2016)
The heart of a fuel cell is the membrane-electrode assembly consisting of two porous electrodes, where the electrochemical reactions take place, and the ionomer conductive membrane, which allows the proton exchange from ...
Efectos de la membrana de intercambio de protones en el desempeño de una celda de combustible H2 O2
(Revista Tecnología y Ciencia UTN, 2016)
Una celda de combustible convierte directamente la energía química de un combustible en electricidad. Su desempeño depende de diferentes parámetros tales como el espesor de la membrana intercambiadora de protones, el ...
Theoretical and experimental study of isothiazolinone adsorption onto ordered mesoporous silica
(Elsevier, 2016)
Mesoporous silica SBA-15 particles were synthesized in order to evaluate their effectiveness asencapsulating agents for a commercial biocide composed of a mixture of methylisothiazolinone andchloromethylisothiazolinone ...
Fibras de refuerzo en pinturas y recubrimientos : parte I
(Atipat, 2016-04-01)
La mayoría de las tecnologías modernas requiere materiales con una combinación inusual
de propiedades, imposibles de diseñar con los existentes en forma individual. Esta
necesidad es muy evidente en aplicaciones espaciales, ...
