Effects of operating parameters on efficiency of cadmium and zinc removal by the complexation-filtration process
(Elsevier, Amsterdam, 2006)
A process for purifying wastewaters containing heavy and toxic metals such as cadmium and zinc by the complexation-filtration process was studied. From previous research, diethylaminoethyl cellulose (DEAE23) was selected ...
Swelling and drug release behavior of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels obtained by gamma irradiation / Bubrenje i kontrolisano otpuštanje aktivnih materija iz poli(2-hidroksietil metakrilat/itakonska kiselina) kopolimernih hidrogelova dobijenih gama ozračivanjem
(Savez inženjera i tehničara Srbije, Beograd, 2006)
The new copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were prepared by gamma irradiation, in order to examine the potential use of these hydrogels in controlled drug release ...
Influence of oxyethylenated alkylamines in the dyeing of polyamide 66 fibres
(Elsevier Sci Ltd, Oxford, 2006)
This paper analyzes the influence of the chemical structure of a series of oxyethylenated laurylamines (LA-EO) on the formation of complexes with the dye C.I. Direct Red 1, as well as on the dyeing kinetics of the polyamide ...
Hydrogen evolution on Ni/WC composite coatings
(Springer, 2006)
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemicaldeposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, ...
Substituent and solvent effects on the UV/vis absorption spectra of 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-eyano-2-pyridones
(Elsevier Science Bv, Amsterdam, 2006)
Absorption spectra of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones have been recorded in 12 protic and aprotic solvents in the range 200-600 nm. The effects of substituents on the absorption ...
Solvent and substituent effect on electronic spectra of N-(4-substituted phenyl)-2,3-diphenylpropanamides
(Arkivoc, 2006)
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects ...
Izrada termoplastičnih kompozitnih cevi metodom namotavanja. III. Proračun termičkih napona / Fabrication of thermoplastic composite pipes using tape winding process. III. Thermal Stresses Calculation
(Društvo inženjera plastičara i gumara, 2006)
Cilj rada je da se na osnovu matematičkog modela procesa namotavanja kompozitnih cevi izvrši numerička simulacija procesa, kako bi se sagledao uticaj procesnih parametara na zaostale napone u kompozitnoj cevi, odnosno na ...
Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
An investigation into the influence of hydrogel composition on swelling behavior and drug release from poly(acrylamide-co-itaconic acid) hydrogels in various media
(Taylor & Francis Ltd, Abingdon, 2006)
The hydrogels prepared by free radical copolymerization of acrylamide and itaconic acid were investigated with regard to their composition and crosslinking degree to find materials with satisfactory swelling and drug release ...
Electrophoretic deposition and characterization of boehmite coatings on titanium substrate
(Elsevier Science Bv, Amsterdam, 2006)
Boehmite aqueous sol was prepared by the peptization of Al(OH)(3). The solid phase, obtained by drying the prepared aqueous sol, was characterized by infrared spectroscopy and X-ray diffraction (pseudoboehmite was confirmed), ...
