Swelling of plant material in supercritical carbon dioxide
(Elsevier, Amsterdam, 2010)
Swelling of plant material belonging to several plant families and the influence of swelling on supercritical fluid extraction process were investigated in this study. While swelling of Lamiaceae family species as well as ...
Synthesis, characterization and controlled release of cephalexin drug from smart poly(2-hydroxyethyl methacrylate/poly(alkylene glycol)(meth)acrylates hydrogels
(Elsevier Science Sa, Lausanne, 2010)
In this work, novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and different poly(alkylene glycol)(meth)acrylates (BIS) were prepared by radiation-induced copolymerization. The influence of different BIS types ...
Corrosion protection of aluminium pretreated by vinyltriethoxysilane in sodium chloride solution
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The corrosion protection of vinyltriethoxysilane (VTES) films on aluminium during exposure to 3% NaCl was investigated using electrochemical impedance spectroscopy (EIS), potential-time measurements and optical microscopy ...
Removal of cadmium from aqueous solutions by oxidized and ethylenediamine-functionalized multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2010)
Surface functionalization of multi-walled carbon nanotubes (MWCNTs) by ethylenediamine, via chemical modification of carboxyl groups, using O-(7-azabenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate, was ...
Improvement of chemical control in the water-steam cycle of thermal power plants
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
A more effective chemical control in the water-steam cycle (WSC) of thermal power plants (TPP) is proposed in this paper. Minimization of corrosion effects by the production of ultra pure water and its strict control is ...
Viscosity of the binary systems 2-methyl-2-propanol with n-alkanes at T=(303.15, 308.15, 313.15, 318.15 and 323.15)K: Prediction and correlation - New UNIFAC-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2010)
Viscosities for the binary mixtures 2-methyl-2-propanol + n-heptane, +n-octane, +n-nonane and +n-decane have been measured at 303.15, 308.15, 313.15, 318.15 and 323.15 K and atmospheric pressure. Viscosity deviations for ...
CdSe/CdS nanoparticles immobilized on pNIPAm-based microspheres
(Royal Soc Chemistry, Cambridge, 2010)
In this work, CdSe/CdS semiconductor ligand-exchanged nanoparticles have been immobilized on poly-(N-isopropylacrylamide) (pNIPAM)-based microspheres. The size and the shrinkage capacity of the spheres can be tuned by the ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
