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 ...
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 ...
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. ...
Electrolysis conditions for obtaining cupric oxide (CUO) / Uslovi dobijanja bakar (II) oksida elektrolitičkim putem
(Belgrade, Serbia : Engineering Society for Corrosion, 2009)
Conditions for obtaining copper powder with different regimes of electrolysis [potentiostatic, galvanostatic and programmed current-voltage regimes ( periodically changing rate)] and effects on it's morphology and ...
Nanomembrane: A New MEMS/NEMS Building Block
(IntechOpen, 2009)
Since nanomembranes are a novel concept which extends the range of MEMS & NEMS building blocks and practically introduces a new one, this means that whole branches of science and technology can be re-read and re-created ...
A study of novel cobalt(II) octaazamacrocyclic complexes with aminocarboxylates or their derivatives / Proučavanje novih kompleksa kobalta(II) sa oktaazamakrociklom i aminokarboksilatima ili njihovim derivatima
(Serbian Chemical Society, 2009)
Four new air-stable mixed-ligand Co(II) complexes having the general formula [Co2(Y)tpmc]Z3×q(H2O/CH3CN) (HY = N-methylglycine/N,N-dimethylglycine, Z = - 4BF , qH2O=4 or 3; HY=S-norvaline/S-valine Z=-ClO4 , qCH3CN = 0.5; ...
The effect of the concentration of the reacting ion on the control of the electrodeposition process / Uticaj koncentracije reagujućeg jona na kontrolu procesa elektrohemijskog taloženja
(Serbian Chemical Society, 2009)
The effect of the concentration of the reacting ion on the nature of the control of the electrodeposition process was investigated by digital simulation of the polarization curve using the Newman form of the polarization ...
Characterization of trypsin-like enzymes from the midgut of Morimus funereus (Coleoptera: Cerambycidae) larvae / Karakterizacija tripsinima-sličnih enzima srednjeg creva larvi Morimus funereus (Coleoptera: Cerambycidae)
(University of Belgrade, University of Novi Sad, 2009)
The pH along the midgut of M. funereus larvae had different values, being acidic in the anterior section and basic in the middle and posterior sections. Elastase- and chymotrypsin-like activities were highest in the middle, ...
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 ...
