Electrical Conductivity of Lignocellulose Composites Loaded with Electrodeposited Copper Powders. Part II. Influence of Particle Size on Percolation Threshold
(Esg, Belgrade, 2012)
This article is concerned with synthesis and characterization of electroconductive composite materials prepared by the compression molding of mixtures of lignocellulose and electrochemically deposited copper powder under ...
Electrodeposition of Fe powder from acid electrolytes / Elektrohemijsko taloženje Fe prahova iz kiselih elektrolita
(Serbian Chemical Society, 2008)
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the obtained powders were investigated. The morphology depended on the anion pre ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
The effect of the fluorides and pH value of the electrolyte on the structure of copper coatings deposited onto aluminum / Uticaj fluorida i pH vrednosti elektrolita na strukturu prevlaka bakra istaloženih na aluminijumu
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
The copper coatings were electrodeposited directly onto aluminum from the following solution: CuSO4-⋅5H2O (55 g/dm3) + CH2 NH2 - CH2OH (100 g/dm3) (NH4)2SO4 (30 g/dm3) + Na2SO4 - 10H2O (75 g/dm3) + Na2CO3 (3g/dm3), room ...
The effect of the particle shape and structure on the flow ability of electrolytic copper powder II: The experimental verification of the model of the representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha II - eksperimentalna potvrda modela reprezentativne čestice praha
(Serbian Chemical Society, 2003)
An analysis of the effects of the shape, surface structure and size distribution of particles on the flow ability of the copper powder was performed. It is shown that the most important property of the particles of a powder, ...
Oscillatory Carbonylation of Poly(Ethylene Glycol)Methyl Ether Acetylene. Modelling of Reaction Mechanism and Stoichiometric Network Stability Analysis
(University of Kragujevac, 2019)
The reaction mechanism of palladium-catalysed oscillatory carbonylation of
poly(ethylene glycol)methyl ether acetylene (PEGA) was examined by stoichiometric
network analysis (SNA) of the stability of the dynamic states. ...
Properties of Ni-W alloys electrochemically deposited by direct and pulse current / Karakteristike legura Ni-W elektrohemijski taloženih konstantnom i pulsirajućom strujom
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
The Ni-W alloys were electrochemically deposited from a ammonia-citrate electrolyte on rotation disc electrode with a replaceable steel disc, by direct and pulsed current. The aim of the paper is investigations of parameters ...
Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder IV: The internal structure of the powder particles / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha IV - unutrašnja struktura čestica praha
(Serbian Chemical Society, 2004)
The structure of powder particleswas analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
Adsorption of nicotine from aqueous solutions on montmorillonite and acid – modified montmorillonite
(International Institute for the Science of Sintering, Beograd, 2019)
Montmorillonite (Mt) and acid modified montmorillonite (MtA) were tested as
nicotine adsorbents. The samples were characterized using FT-IR spectroscopy and low
temperature nitrogen physisorption. Nicotine adsorption was ...
