Modelling of non-catalytic biodiesel synthesis under sub and supercritical conditions: The influence of phase distribution
(Elsevier, Amsterdam, 2012)
Biodiesel, a mixture of fatty acid methyl esters, is widely used as renewable bio-based alternative fuel for internal combustion engines. Kinetic model of non-catalytic biodiesel synthesis at elevated temperature and ...
Toxic metal health risk by mussel consumption
(Springer Heidelberg, Heidelberg, 2012)
Seafood is a major dietary food worldwide. However, seafood consumption by humans can induce health risk because seafood may be contaminated by various pollutants. The mussel Mytilus galloprovincialis is widely distributed ...
Removal of Sulfur Compounds from Mineral Insulating Oils by Extractive Refining with N-Methyl-2-pyrrolidone
(Amer Chemical Soc, Washington, 2012)
Copper sulfide deposits in the insulation systems of power transformers decrease the dielectric properties of the insulation and therefore constitute a significant risk for the operation of power transformers. Disulfides, ...
The possibility of obtaining. Composite al18wt%si/sic by compocasting process
(Modtech Publishing House, Iasi, 2012)
The aim of this study was to investigate the influence of various process parameters on the microstructure of composite materials based on alloys All 8Wt%Si with the addition of 10Wt%SiC. The effect of stirring speed (1000 ...
Linear free energy relationships applied to the reactivity and the C-13 NMR chemical shifts in 4-[[(substituted phenyl)imino]methyl]benzoic acids
(Elsevier Science Bv, Amsterdam, 2012)
Linear free energy relationships (LFER) were applied to the kinetic data and C-13 NMR chemical shifts in 4-[[(substituted phenyl)imino]methyl]benzoic acids. The correlation analysis for the kinetic data and substituent-induced ...
Alginate hydrogel microbeads incorporated with Ag nanoparticles obtained by electrochemical method
(Elsevier Science Sa, Lausanne, 2012)
An innovative method was developed for production of alginate hydrogel microbeads incorporated with silver nanoparticles (AgNPs) based on electrochemical synthesis followed by electrostatic extrusion. AgNPs were synthesized ...
Removal of Pb2+ Ions from Water by Poly(Acrylamide-co-Sodium Methacrylate) Hydrogels
(Springer, Dordrecht, 2012)
The application of poly(acrylamide-co-sodium methacrylate) (AAm/SMA) hydrogel for the removal of Pb2+ ions from aqueous solutions has been investigated using batch adsorption technique. The extent of adsorption was ...
Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Microstructure evolution of a modified AA5083 aluminum alloy during a multistage homogenization treatment
(Elsevier Science Inc, New York, 2012)
The microstructure evolution of the industrially cast AA5083 modified aluminum alloy during the multistage homogenization treatment was investigated by means of optical, SEM and TEM imaging and microanalysis techniques. ...
