Functionalized macroporous copolymer of glycidyl methacrylate: The type of ligand and porosity parameters influence on Cu(II) ion sorption from aqueous solutions / Funkcionalizovani makroporozni kopolimer na bazi glicidilmetakrilata - uticaj liganda i parametara poroznosti na sorpciju Cu(II) jona iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2009)
The removal of heavy metals from hydro-metallurgical and other industries' wastewaters, their safe storage and possible recovery from waste- water streams is one of the greater ecological problems of modern society. ...
Elektrohemijsko dobijanje i morfologija čestica bakarnog praha dobijenog pri različitim retimima elektrolize / Electrodeposition and morphology of copper powder particles obtained at different current regimes
(Bosnia and Herzegovina : University of East Sarajevo, Faculty of Technology, 2009)
Ispitivan je uticaj različitih reţima elektrolize (konstantna i reversna struja) na morfologiju bakarnog praha. Morfologija istaloţenog bakarnog praha je proučavana pomoću skening elektronskog mikroskopa (SEM). Diskutovan ...
Rapid pyrolysis of Serbian soft brown coals
(VINCA Institute of Nuclear Sciences, 2009)
Soft brown coals of the open coal fields of Kolubara and Kostolac are the main domestic energy sources of Serbia. This paper presents the results of investigations on rapid devolatilization of these two coals which have ...
Corrosion causes in thermal power plants and ways of prevention / Uzroci korozije u termoenergetskim postrojenjima i načini prevencije
(Belgrade, Serbia : Engineering Society for Corrosion, 2009)
Corrosion damages often exert considerable influence on outages number and hence on the loss of thermal power plant availability. In order to accomplish the aim of reducing the corrosion to it's minimum and prevent main ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...
