Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
The influence of modification on structural, textural and adsorption properties of bentonite / Uticaj modifikacije na strukturna, teksturalna i adsorpciona svojstva bentonita
(Assoc Chemical Engineers Serbia, Belgrade, 2008)
Natural bentonite clay from the Bogovina locality in Serbia was Na-exchanged and modified using hexadecyll-trimethylammonium bromide as surfactant and organobentonite was obtained. The influence of modifications on the ...
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, ...
The morphology of copper powder obtained by different regimes of electrolysis / Morfologija bakarnog praha dobijenog različitim režimima elektrolize
(Belgrade, Serbia : Engineering Society for Corrosion, 2006)
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The morphology of electrodeposited copper powder were investigated using a ...
The effect of preparation of aluminum surface on surface roughness / Uticaj pripreme površine aluminijuma na površinsku hrapavost
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
Aluminum samples were electrochemically polished in one of three solutions for electrochemical polishing. On those samples the surface roughness was measured. The effect of the anode treatment on surface roughness was also ...
Direct electroplating of copper coatings onto aluminum / Neposredno elektrohemijsko taloženje prevlaka bakra na aluminijum
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
The deposition of copper coatings has been done by direct electrochemical deposition from the solution: CuSO4 (55 g/dm3) + CH2 NH2 - CH2OH (100 g/dm3) + (NH4)2SO4 (30 g/dm3) + Na2SO4*10H2O (75 g/dm3) + Na2CO3 (3 g/dm3), ...
The effect of preparation of aluminum surface on surface reflection / Uticaj pripreme površine aluminijuma na površinsku refleksiju
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
Aluminum samples were electrochemically polished in one of three solutions for electrochemical polishing. On those samples the surface reflection was measured. The effect of the anode treatment as the interface between the ...
