Electrical properties of the SnO2-based varistor
(1998-12-01)
The non-linear electrical properties of CoO-doped and Nb205-doped SnO2 ceramics were characterized. X-ray diffraction and scanning electron microscopy indicated that the system is single phase. The electrical conduction ...
Application of chitosan emulsion as a coating on Kraft paper
(Wiley-blackwellMaldenEUA, 2011)
Evaluation of edible films and coatings formulated with cassava starch, glycerol, carnauba wax and stearic acid
(Elsevier Sci LtdOxfordInglaterra, 2014)
Influence of the relative amounts of crystalline and amorphous phases on the mechanical properties of polyamide-6 nanocomposites
(WILEY-BLACKWELLMALDEN, 2012)
The relative amounts of amorphous and crystalline ?- and a-phases in polyamide-6 nanocomposites, estimated from the deconvolution of X-ray diffraction peaks using Gaussian functions, correlates with their mechanical, ...
Barrier Properties and Structural Study of Nanocomposite of HDPE/Montmorillonite Modified with Polyvinylalcohol
(Hindawi Publishing Corporation, 2013-02)
In this work was studied the permeation of CO2 in films of high-density polyethylene (HDPE) and organoclay modified with polyvinylalcohol (MMTHDTMA/PVA) obtained frommelt blending. Permeation study showed that the incorporation ...
Characterization of quinoa protein-chitosan blend edible films
(2011)
Quinoa protein/chitosan films were obtained by solution casting of blends of quinoa protein extract (PE) and chitosan (CH). Films from a PE/CH blend were characterized by FTIR, X-ray diffraction, thermal analysis, and SEM. ...
Correlations between structural, barrier, thermal and mechanical properties of plasticized gelatin films
(Elsevier, 2010-04)
The aims of this work were to develop gelatin films using glycerol as plasticizer (0-100% based on protein mass) and to establish relationships between glycerol content and structural, barrier, thermal and mechanical film ...
Effect of the type of clay organo-modifier on the morphology, thermal/ mechanical/ impact/barrier properties and biodegradation in soil of polycaprolactone/clay nanocomposites
(John Wiley & Sons Inc, 2012-08-23)
The effect of addition of unmodified (CNaþ) and modified (C30B and C20A) montmorillonites on the performance of polycaprolactone (PCL) based nanocomposites prepared by melt intercalation was studied. The study covers ...
