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. ...
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 ...
Rinsed and thermally treated red mud sorbents for aqueous Ni2+ ions
(Elsevier Science Sa, Lausanne, 2010)
Red mud, an abundant industrial waste from alumina industry, represents a rich source of various metal oxides, mainly of Fe2O3 Al2O3 and SiO2. In this study, the rinsed Bosnian red mud (RBRM) was evaluated as an economical, ...
Nonlinear Frequency Response of Electrochemical Methanol Oxidation Kinetics: A Theoretical Analysis
(Electrochemical Soc Inc, Pennington, 2010)
In this theoretical contribution, nonlinear frequency response analysis was applied for the investigation of electrochemical methanol oxidation. This technique expresses the input-output behavior of any weakly nonlinear ...
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 ...
1-Butanol + hexylamine plus n-heptane at temperature range (288.15-323.15 K): Experimental density data, excess molar volumes determination and modeling with cubic EOS
(Elsevier Science Bv, Amsterdam, 2010)
Densities rho of the ternary system 1-butanol + hexylamine + n-heptane and binaries: 1-butanol + hexylamine and hexylamine + n-heptane within the temperature range (288.15-323.15K) and atmospheric pressure are reported. ...
Preparation of MEMO silane-coated SiO2 nanoparticles under high pressure of carbon dioxide and ethanol
(Elsevier, Amsterdam, 2010)
The objective of this study is to investigate and compare methods of nanosilica coating with gamma-methacryloxypropyltrimethoxy (MEMO) silane using supercritical carbon dioxide and carbon dioxide-ethanol mixture. ...
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 ...
Optimal conceptual design of processes with heterogeneous catalytic reactors
(Elsevier Science Sa, Lausanne, 2010)
This paper presents an optimisation-based method for the screening and conceptual design of processes with heterogeneous catalytic reactors. The method follows a multi-level approach to process synthesis to establish ...
Extraction of sage (Salvia officinalis L.) by supercritical CO2: Kinetic data, chemical composition and selectivity of diterpenes
(Elsevier Science Bv, Amsterdam, 2010)
The supercritical carbon dioxide (SFE) extraction of Dalmatian sage (Salvia officinalis L) was investigated and compared to extraction performed by Soxhlet ethanol-water (70:30) mixture extraction (SE) and hydrodistillation ...
