A study on X-ray irradiation of composite polyaniline LB films
(Elsevier B.V., 1998-08-31)
Composite Langmuir-Blodgett (LB) films from polyaniline and cadmium stearate have been irradiated with ionizing X-rays for various exposure times. In the initial stages of X-ray irradiation the absorption peak at 580 nm ...
Films from resistant starch-pectin dispersions intended for colonic drug delivery
(2014-01-01)
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...
Structural and surface morphology characterizations of oriented LiNbO3 thin films grown by polymeric precursor method
(1999-06-01)
Polymeric precursor solution was used to deposit LiNbO3 thin films by dip coating on sapphire substrates. The effects of processing variables, such as heat treatment conditions and number of deposited layers, on crystallinity ...
Ferroelectric SBN thin films grown by an SBN/Bi2O3 PLD sequential process
(2001-10-01)
Ferroelectric SrBi2Nb2O9 (SBN) thin films were prepared by pulsed laser deposition (PLD) on Pt/Ti/SiO2/Si(100) using a sequential deposition process from two SBN and Bi2O3 targets. This route allows for bismuth enrichment ...
Influence of oxygen atmosphere on crystallization and properties of LiNbO3 thin films
(Elsevier B.V., 2004-01-01)
Thin films of lithium niobate were deposited on the Pt/Ti/SiO2 (111) substrates by spin coating from the polymeric precursor method (Pechini process). Annealing in static air and oxygen atmosphere was performed at 500 ...
Influence of Mg on the structural and optical properties of LiNbO3 thin films grown by polymeric precursor method

Biodegradability of PP/PHBV (70/30) blend films
(2013-12-01)
This study aimed to investigate the biodegradation of polypropylene/ poly(hydroxybutyrate-co-hydroxyvalerate) (PP/PHBV) blend (70/30, w/w) films in soil, monitoring the evolution of CO2 using the respirometric method. The ...
Polymeric precursor method to the synthesis of XWO(4) (X = Ca and Sr) thin films-Structural, microstructural and spectroscopic investigations
(Elsevier B.V. Sa, 2009-05-27)
Stoichiometric XWO(4) (X = Ca, and Sr) thin films were synthesized using the polymeric precursor method. In this soft chemical method, soluble precursors such as strontium carbonate, calcium carbonate and tungstic acid, ...
Crystallization of amorphous GaAs films prepared onto different substrates
(2002-04-01)
This work reports changes in structural properties produced by thermal annealing of flash evaporated amorphous GaAs films using the micro-Raman scattering and the X-ray diffraction (XRD) techniques. Films of about 1 μm ...
Effects of processing on the structure of zein/oleic acid films investigated by X-ray diffraction
(Wiley-Blackwell, 2005-12-15)
Zein films plasticized with oleic acid were formed by solution casting, by the stretching of moldable resins, and by blown film extrusion. The effects of the forming process on film structure were investigated by X-ray ...
