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 ...
Electrospun nanofibre membranes functionalised with TiO2 nanoparticles: Evaluation of humic acid and bacterial removal from polluted water
(Elsevier Science Bv, Amsterdam, 2015)
This study presents contact experiments and filtration tests with nanofibre membranes containing TiO2 nanoparticles in view of effluent treatment. The first part of this study focuses on the removal of dissolved organic ...
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 ...
Antimicrobial activity of copper and zinc-doped hydroxyapatite nanopowders
(Elsevier Science Bv, Amsterdam, 2011)
Isolation and Biological Evaluation of Jatrophane Diterpenoids from Euphorbia dendroides
(Amer Chemical Soc, Washington, 2011)
From the Montenegrin spurge Euphorbia dendroides, seven new diterpenoids [jatrophanes (1-6) and a tigliane (7)] were isolated and their structures elucidated by spectroscopic techniques. The biological activity of the new ...
Electrochemical synthesis and characterization of polyaniline thin film and polyaniline powder
(Elsevier Science Sa, Lausanne, 2011)
The polyaniline thin film electrode and powder have been synthesized on graphite electrodes from 0.5 M hydrochloric acid solution under galvanostatic conditions. The water insoluble and acetone soluble polyaniline mass ...
Novel properties of PES fabrics modified by corona discharge and colloidal TiO2 nanoparticles
(Wiley, Hoboken, 2011)
The objective of this study was to highlight the potential application of the corona discharge at atmospheric pressure for the surface activation of polyester (PES) fabrics in order to improve the binding efficiency of ...
Liquid-liquid phase equilibria in nicotine (aqueous) solutions
(Elsevier, Amsterdam, 2011)
Liquid-liquid equilibria were measured for solutions containing: (1) nicotine, and one of the solvents PEG 200 or ethyl-lactate, and the ionic liquid 1-ethyl-3-methylimidazolium ethyl sulphate (ECOENG 212 (R)); (2) a ...
Deciduous tree leaves in trace elements biomonitoring: A contribution to methodology
(Elsevier Science Bv, Amsterdam, 2011)
Air quality biomonitoring using plant leaves has been widely applied to assess the effects of atmospheric pollution. Although practiced for many years, it has not given completely satisfactory data, due to different and ...
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 ...
