Preparation and structural characterization of vulcanized natural rubber nanocomposites containing nickel-zinc ferrite nanopowders
(Journal of Nanoscience and Nanotechnology, 2012-03-01) [Artigo]
Single-phase polycrystalline mixed nickel-zinc ferrites belonging to Ni0.5Zn0.5Fe2O4 were prepared on a nanometric scale (mean crystallite size equal to 14.7 nm) by chemical synthesis named the modified poliol method. ...
A comparative solid state C-13 NMR and thermal study of CO2 capture by amidines PMDBD and DBN
(Green Chemistry, 2011-01-01) [Artigo]
The present work shows study of the CO2 capture by amidines DBN and PMDBD using C-13 solid-state NMR and thermal techniques. The solid state C-13 NMR analyses demonstrate the formation of a single PMDBD-CO2 product which ...

(Journal Of Applied Polymer Science, 2015-02-15) [Artigo]
The incorporation of residues as reinforcing fillers in polymer composites has emerged as a viable solution, enabling improvements in the mechanical properties of these materials, and has also resulted in a reduction in ...
Natural rubber/leather waste composite foam: A new eco-friendly material and recycling approach
(Journal Of Applied Polymer Science, 2015-03-15) [Artigo]
This article describes a new approach of recycling the leather waste (shavings) using it as filler in natural rubber foams composites. The foams were prepared using different amounts of leather waste (0-60 parts per hundred ...
Pyrolysis and auto-gasification of black liquor in presence of ZnO: An integrated process for Zn/ZnO nanostructure production and bioenergy generation
(Biomass & Bioenergy, 2012-11-01) [Artigo]
This study presents a new process for valorisation of black liquor into gases that are used to reduce ZnO and promote zinc nanosheet synthesis, besides energy generation. During the black liquor pyrolysis and auto-gasification, ...
Molecular and morphological characterization of bis benzimidazo perylene films and surface-enhanced phenomena
(Journal of Physical Chemistry B, 2008-04-03) [Artigo]
Thin solid films of bis benzimidazo perylene (AzoPTCD) were fabricated using physical vapor deposition (PVD) technique. Thermal stability and integrity of the AzoPTCD PVD films during the fabrication (similar to 400 degrees ...
Molecular architecture of thin films fabricated via physical vapor deposition and containing a poly(azo)urethane
(Journal of Nanoscience and Nanotechnology, 2010-05-01) [Artigo]
Organic thin films are widely applied as transducers in devices whose performance is determined by the optical and electrical properties of the films. In this context, the molecular architecture of the thin films plays an ...
