The particle size distribution (PSD) as criteria for comparison of silver powders obtained by different methods of synthesis and by conditions of electrolysis
(Bor : Technical Faculty, 2018)
Silver powders produced by both electrochemical (galvanostatic (DC) and potentiostatic (POT) regimes of electrolysis) and chemical processes were examined by scanning electron microscope, and particle size distribution ...
Laser cleaning of the archaeological metal sample from the Danube / Istraživanje mogućnosti primene lasera u čišćenju arheoloških metalnih predmeta
(Belgrade, Serbia : Engineering Society for Corrosion, 2018)
The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The ...
Correlation between crystal structure and morphology of potentiostatically electrodeposited silver dendritic nanostructures
(Elsevier, 2018)
Silver dendritic nanonstructures obtained by the potentiostatic electrolysis from different electrolytes at different overpotentials were characterized by the scanning electron microscopy (SEM) technique and X-ray diffraction ...
The effect of deposition temperature on the surface coverage and morphology of iron-phosphate coatings on low carbon steel
(Elsevier, 2011)
The influence of deposition temperature and concentration of NaNO(2) in the phosphating bath on the surface morphology and coverage of iron-phosphate coatings on low carbon steel was investigated. The phosphate coatings ...
Influence of the Shape of Copper Powder Particles on the Crystal Structure and Some Decisive Characteristics of the Metal Powders
(MDPI, 2019)
Three different forms of Cu powder particles obtained by either galvanostatic electrolysis or a non-electrolytic method were analyzed by a scanning electron microscope (SEM), X-ray diffraction (XRD) and particle size ...
Morphology and structure of bright electrodeposited metal coatings
(Soc Chemists Technologists Madeconia, Skopje, 2011)
The properties which determine whether the metal surface is mirror bright are precisely determined by scanning electron microscopy (SEM), atomic forces microscopy (AFM), scanning tunneling microscopy (STM) and reflectance ...
Interactive Catalytic Performances of Carbonaceous Materials in Electrochemistry
(New York, USA : Nova Science Publishers Inc., 2019)
The attraction of carbon as an electrode material arises from its unique chemical and physical properties: high conductivity, good corrosion resistance, high temperature stability, high surface-area range (∼1 to >2000 m2 ...
Corrosion stability of Zn-Co alloys deposited from baths with high and low Co content - The influence of deposition current density
(Elsevier, 2010)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) ...
Synthesis and properties of bis(pyrrolidino)fullerenes bridged by a flexible alkyl-tether
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The one-pot bistycloaddition of alkyl-tethered diglycines to C-60 provided five series of bridged bis(pyrrolidino)fullerenes with good regioselectivity, giving mainly cis-2 and cis-3 products. An influence of the bridge ...
Structural investigation of mechanically activated ZnO powder
(Elsevier, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
