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 ...
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 ...
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 ...
