The response of peritoneal macrophages to dapsone covalently attached on the surface of carbon nanotubes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Dapsone is an anti-microbial and anti-inflammatory drug. Water-dispersible dapsone-modified multi-wall carbon nanotubes (dap-MWCNTs) were prepared by chemical modification of the carboxyl groups introduced on the surface ...
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 ...
Microgel-based surface modifying system for stimuli-responsive functional finishing of cotton
(Elsevier Sci Ltd, Oxford, 2010)
An innovative strategy for functional finishing of textile materials is based on the incorporation of a thin layer of surface modifying systems (SMS) in the form of stimuli-sensitive microgels or hydrogels. Since the ...
Aqueous Pb sorption by synthetic and natural apatite: Kinetics, equilibrium and thermodynamic studies
(Elsevier Science Sa, Lausanne, 2010)
Natural apatites represent a cost effective soil amendment, which can be used for in situ reduction of lead bioavailability and mobility. In our previous work, we selected Lisina apatite (LA) as a promising natural mineral ...
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 ...
Phase transition at subcritical and supercritical conditions of triglycerides methanolysis
(Elsevier, Amsterdam, 2010)
The analysis of phase equilibrium between methanol and glycerides during methyl esters of fatty acids (FAME or biodiesel) synthesis at high pressure and temperature is very important for describing the kinetic and process ...
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 ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
