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. ...
On the zinc sorption by the Serbian natural clinoptilolite and the disinfecting ability and phosphate affinity of the exhausted sorbent
(Elsevier, Amsterdam, 2011)
The Serbian natural zeolite is moderately effective in removing the zinc(II) ions from aqueous solutions. At 298 K the sorption capacity varies from 13 to 26% for the initial Zn(II) solution concentration of 100 and 600 ...
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. ...
Nonlinear Frequency Response Analysis of the Ferrocyanide Oxidation Kinetics. Part I. A Theoretical Analysis
(Amer Chemical Soc, Washington, 2011)
In this work, a nonlinear frequency response (NLFR) analysis was used for a first time in a theoretical study of nonlinear behavior of electrochemical (EC) ferrocyanide oxidation as a simple model reaction. Analytical ...
Inhibition properties of self-assembled corrosion inhibitor talloil diethylenetriamine imidazoline for mild steel corrosion in chloride solution saturated with carbon dioxide
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The inhibition effect of talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on corrosion of mild steel in chloride solutions saturated with CO2 was investigated by weight loss measurements (WL) and atomic force ...
The EIS investigation of powder polyester coatings on phosphated low carbon steel: The effect of NaNO2 in the phosphating bath
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of different type of iron-phosphate coatings on corrosion stability and adhesion characteristic of top powder polyester coating on steel was investigated. Iron-phosphate coatings were deposited on steel in the ...
Electrochemical determination of glucose using polyaniline electrode modified by glucose oxidase
(Elsevier Sci Ltd, Oxford, 2011)
Polyaniline (PANI) enzyme electrode was formed by immobilisation of Glucose oxidase (GOx) via glutaraldehyde into electrochemically polymerised PANI on graphite electrode. Electrochemical polymerisation of PANI on graphite ...
