Biopolymer nanocomposite films were prepared by casting film-forming emulsions based on chitosan/Tween 80/rosehip seed oil and dispersed montmorillonite nanoclay C30B. The effect of composition structural, morphological characteristics and, mechanical, barrier, antimicrobial antioxidant properties was studied. presence rosehip in chitosan led to the formation flexible with improved gas water vapour barrier activity. vitro antibacterial tests against Escherichia coli, Salmonella typhymurium,...
Poly(vinyl alcohol) (PVA)/chitosan (CS)/montmorillonite (C30B) materials for food packaging applications were prepared by using a noninvasive and low-cost freeze/thawing method. Cloisite 30B nanoclay content in PVA/CS gels was varied order to establish optimum amount obtain improved properties. The structural, morphological, rheological aspects, thermal stability, antimicrobial activity investigated various techniques as Fourier transform infrared, scanning electron microscopy, rheology,...
Abstract Polyvinyl alcohol (PVA) and chitosan (CS) based hydrogels are often chosen to obtain as being considered non-toxic for human body. The present study aims the preparation physical chemical characterisation of PVA CS by using an environmental friendly method i.e. freeze/thaw. In this only parameters affecting hydrogels’ properties is concentration in solution, time number cycles freezing / thawing. Repeated thawing resulted production a highly elastic polyvinyl hydrogel with higher...
Forestry residue is a renewable energy biomass whose valorization has increased due to the interest in replacing exhaustible and environmentally unfriendly fossil resources. Needles, cones bark from silver fir were thermally processed by separated combined torrefaction (250 °C) pyrolysis (550 °C). The removed humidity extractives degraded hemicelluloses, significantly decreasing oxygen content ~11 wt% increasing carbon ~80 wt%, while enhancing calorific value of solids (~32 MJ/kg). produced...
Catalytic steam gasification of shells (almond and walnut) was carried out in a flow-type double-bed microreactor. Temperature-programmed thermal performed at 200–850 °C, followed by the catalytic volatiles (including tar) different temperatures. The iron–ceria catalyst red mud (as iron oxide catalyst) were used as bed material. Effects on tar decomposition investigated. enhanced both degradation hydrogen production via water–gas shift reaction. conversions 94% (for almond shell) 100% walnut...
The effect of biomass (Eucalyptus globulus, pine cones, and Brassica rapa) composition on the γ-irradiation behavior some polypropylene (PP) biocomposites has been studied. variations in mechanical properties, contact angles, crystallinity index, hydroxyl carbonyl indices, induction period oxidative process indicated a strong influence under γ-irradiation. high dose influences properties PP biocomposites. angle values irradiated samples decreased with respect to unirradiated PP/biomass...
Quantitative determination of ethanol from blood is used for scientific research, evaluation metabolism in the human body or forensic laboratory. The aim our paper to develop and validate a method order determine quantity using gas chromatography with headspace. We GC 6890 N Agilent equipment, headspace G 1888, two columns alcohol analysis (DB-ALC1 DB-ALC2) FID detectors. retention time has been higher when column DB-ALC1 (1.362 min) rather than DB- ALC2 (1.313 min). Internal standard this...
Pain is defined as a disagreeable sensory and emotional experience related to tissue or potential lesion. Paracetamol (Acetaminophen) the most used non-morphine analgesic. For determination of paracetamol we developed validated high performance liquid chromatography (HPLC) analysis using Dionex Ultimate 3000 chromatograph equipped with multidimensional detector. After determining optimum conditions (80/20 water / acetonitrile mobile phase, flow rate 1.0 mL min, detection wavelength 245 nm)...
