Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Influence of starch sodium octenyl succinate on rheological behaviour of wheat flour dough systems
(Elsevier Sci Ltd, Oxford, 2013)
Experimental and theoretical influence of addition of various amounts of three types starch sodium octenyl succinate (OSA) granules (0-20%): (a) non-physically modified, (b) pregelatinized and
Functionalization of textile materials with TiO2 nanoparticles
(Elsevier Science Bv, Amsterdam, 2013)
Extraordinary photocatalytic activity, non-toxicity, high availability, biocompatibility, and low price make TiO2 nanoparticles particularly attractive for manufacturing of different high value-added products. During the ...
Extensive feedwater quality control and monitoring concept for preventing chemistry-related failures of boiler tubes in a subcritical thermal power plant
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Prevention and minimizing corrosion processes on steam generating equipment is highly important in the thermal power industry. The maintenance of feedwater quality at a level corresponding to the standards of technological ...
Effect of austempering temperature on cavitation behaviour of unalloyed ADI material
(Elsevier Science Inc, New York, 2013)
This paper provides an in-depth study and description of cavitation damage and microstructural changes in two types of unalloyed austempered ductile iron (ADI). ADI materials used were austempered at 300 and 400 degrees C ...
Molecular weight distribution and functional group profiles of TEMPO-oxidized lyocell fibers
(Elsevier Sci Ltd, Oxford, 2013)
The effects of TEMPO-mediated oxidation, performed with NaClO, a catalytic amount of NaBr, and 2,2',6,6'-tetramethylpiperidine-1-oxy radical (TEMPO), were studied on lyocell fibers by means of GPC using multiple detection ...
A Novel Method to Mitigate the Top-of-the-Line Corrosion in Wet Gas Pipelines by Corrosion Inhibitor within a Foam Matrix
(Natl Assoc Corrosion Eng, Houston, 2013)
Top-of-the-line corrosion (TLC) has been a serious issue for the oil and gas industry. Conventional inhibition techniques are expensive and often do not seem to provide enough protection to the steel surface at the top of ...
The influence of citrate anion on Ni(II) removal by raw red mud from aluminum industry
(Elsevier Science Sa, Lausanne, 2013)
The removal of Ni(II) from aqueous solutions by raw red mud powder was studied in the absence and in the presence of citrate ligand, as a function of process parameters. Using lower initial Ni(II) concentration (10(-3) ...
Multi-level finite element analysis for progressive damage behavior of HA/PEEK composite porous structure
(Elsevier Sci Ltd, Oxford, 2013)
A three-dimensional multi-level finite element (FE) modeling approach has been developed to simulate mechanical response and progressive damage behavior of hydroxyapatite/polyetheretherketone (HA/PEEK) porous structures ...
