Surface characteristics and modification of different carbon materials
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken ...
Copolymer hydrogels based on N-isopropylacrylamide and itaconic acid
(Elsevier Sci Ltd, Oxford, 2006)
In this study, the swelling behaviour of copolymer hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) in response to temperature and pH value of the external media was studied. The equilibrium degree of ...
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 ...
Electrochemical deposition and corrosion stability of Zn-Co alloy coatings / Elektrohemijsko taloženje i koroziona stabilnost prevlaka Zn-Co legura
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
The influence of the type of the deposition solution, deposition current density and temperature of deposition solution on the phase structure and corrosion properties of Zn-Co alloys was examined. Alloys were deposited ...
Removal of heavy metal ions from water by complexation-assisted ultrafiltration
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Toxic heavy metals in air, soil and water are global problems that are growing threat to the environment. Therefore, the removal and separation of toxic and environmentally relevant heavy metal ions are a technological ...
Laminar composite materials damage monitoring by embedded optical fibers
(16th European Conference of Fracture, 2006)
Effect of annealing temperature on the formability of Al-Mg4.5-Cu0.5 alloy sheets
(Elsevier Science Sa, Lausanne, 2006)
Formability of Al-Mg4.5-Cu0.5 alloy sheets was tested after annealing at different temperatures (220-520 degrees C) and water quenching. The formability (normalized limiting dome heights, LDH/R) showed only a small variation ...
Kinetics of the mild steel corrosion protection by polypyrrole-oxalate coating in sulfuric acid solution
(Elsevier Science Sa, Lausanne, 2006)
Kinetics of the mild steel corrosion protection in 0.1 mol dm(-3) H2SO4 by polypyrrole coatings have been investigated by the means of electrochemical impedance spectroscopy (EIS), cyclic voltammetry, polarization measurements ...
Optimization of the electrostatic droplet generation process for controlled microbead production: Single nozzle system / Optimizacija elektrostatičkog generisanja čestica u cilju kontrolisanja njihovih mikronskih veličina - sistem sa jednom mlaznicom
(Association of the Chemical Engineers of Serbia, 2006)
The aim of this study was to optimize the electrostatic extrusion process for producing small, spherical and uniform microbeads with different fluid viscosities by varying the operating parameters in very wide ranges. ...
Application of nonlinear frequency response to investigation of membrane transport
(Taylor & Francis Inc, Philadelphia, 2006)
The concept of higher order frequency response functions, used for investigation of weekly nonlinear systems by frequency response techniques, is applied to investigation of membrane systems. Isothermal permeation of single ...
