The influence of aluminium surface pretreatment on the corrosion stability and adhesion of powder polyester coating
(Elsevier Science Sa, Lausanne, 2010)
One of the most important factors in corrosion prevention by protective coatings is the coating adhesion loss under environmental influence. Thus, adhesion strength is often used when characterizing protective properties ...
Voltammetric and differential pulse determination of roxithromycin
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The oxidative behavior of antibiotic roxithromycin standard was studied at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry and differential pulse voltammetry. It was found that the value of the ...
The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
Corrosion stability of polyester coatings on steel pretreated with different iron-phosphate coatings
(Elsevier Science Sa, Lausanne, 2011)
The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was ...
Investigation of gas transport through porous membranes based on nonlinear frequency response analysis
(Springer, New York, 2011)
Theoretical development of a new experimental method for investigation of mass transport in porous membranes, based on the principle of the modified Wicke-Kallenbach diffusion cell and the nonlinear frequency response ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(University of Belgrade, Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
Radiation-induced synthesis and swelling properties of p(2-hydroxyethyl methacrylate/itaconic acid/oligo (ethylene glycol) acrylate) terpolymeric hydrogels
(Radiation Physics and Chemistry, 2012)
Since it is presumed that by incorporation of pH-responsive (IA) and temperature-responsive (OEGA) co-monomers, it is possible to prepare P(HEMA/IA/OEGA) hydrogels with dual (pH and thermo) responsiveness, the main purpose ...
Fenitrothion adsorption - desorption on organo - minerals
(Elsevier, Amsterdam, 2011)
The adsorption-desorption of the pesticide fenitrothion on organo-montmorillonite, organo-clinoptilolite and organo-sepiolite was studied at different loadings of stearyl- dimethylbenzylammonium cations (SDBA). The SDBA ...
Development of advanced floating poly(lactic acid)-based materials for colored wastewater treatment
(Journal of Supercritical Fluids, 2021)
The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous ...
The nucleation of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal conditions
(Elsevier, Amsterdam, 2010)
The nucleation of germanate K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal conditions was studied by the DTA method. The temperature ranges of nucleation and crystal growth of this glass partly overlap. ...
