AB  - Comparative analysis of morphological and structural features of copper dendrites obtained by potentiostatic and galvanostatic regimes of electrolysis was made. The 3D (three dimensional) pine-like dendrites composed from stalk and corncob-like forms as branches, with the sharp tips of both stalk and branches, were obtained by the potentiostatic regime of electrolysis with all analyzed amounts of passed electricity. On the other hand, with increasing the amount of the passed electricity the shape of 3D pine-line dendrites obtained by the galvanostatic regime of electrolysis changed than those with the sharp tips of stalk and branches to those which the tips finished globules. Comparing with Cu deposits obtained at overpotentials which belonged to different types of electrodeposition control, it is concluded that overpotential at the end of passed amount of the electricity plays crucial role in the final shape of galvanostatically produced Cu dendrites. Irrespective of the shape of Cu dendrites, crystallites of copper were random oriented in the both types of dendrites.
AB  - Napravljena je uporedna analiza morfoloških i strukturnih karakteristika dendrita bakra dobijenih potenciostatskim i galvanostatskim režimima elektrolize. Trodimenzionalni (3D) dendriti nalik stablu bora izgrađeni od stabla i grana koje nalikuju klipovima kukuruza, sa oštrim vrhovima, su bili dobijeni potenciostatskim režimom elektrolize sa svim analiziranim količinama propuštenog naelektrisanja. Na drugoj strani, sa povećanjem količine propuštenog naelektrisanja oblik 3D dendrita dobijenih galvanostatskim režimom elektrolize se menjao od onih sa oštrim vrhovima i stalka i grana do onih čiji vrhovi su se završavali globulama. Poređenjem sa talozima bakra dobijenim na prenapetostima koje su pripadale različitim tipovima kontrole procesa elektrohemijskog taloženja, zaključeno je da prenapetost na kraju propuštene količine naelektrisanja igra presudnu ulogu u krajnjem obliku galvanostatski proizvedenih Cu dendrita. Bez obzira na oblik Cu dendrita, kristaliti bakra su bili slučajno orijentisani u oba tipa dendrita.

AB  - The processes of electrodeposition from magnesium nitrate hexahydrate melt by galvanostatic regime of electrolysis
have been analyzed. The structure of the formed particles was examined by X-ray diffraction (XRD),
which revealed formation of MgO/Mg(OH)2 mixture by molten salt electrolysis. Morphologies of the produced
deposits were characterized by scanning electron microscopy (SEM) technique. The flower-like forms constructed
from very thin needles with sharp tips were predominately formed by electrodeposition at various
current densities and with various amounts of electricity. Aside from that, holes formed from detached hydrogen
bubbles of various shapes and sizes, from dish-like holes to those resulting in honeycomb-like structures were
also observed. Mechanism of formation of the flower-like forms has been elucidated applying the general theory
of disperse deposits formation which is based on the concept of local (spherical and cylindrical) diffusion fields.
It is shown that the growth of the needles occurs under the conditions of predominant spherical diffusion control,
while the contribution of the cylindrical diffusion to the final shapes was negligible. Comparison with
morphologies of deposits obtained by electrodepositions from aqueous magnesium salt electrolytes was also
made and discussed.

AB  - 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 distribution (PSD). Electrolytic procedures were performed under different hydrogen evolution conditions, leading to the formation of either 3D branched dendrites or disperse cauliflower-like particles. The third type of particles were compact agglomerates of the Cu grains, whose structural characteristics indicated that they were formed by a non-electrolytic method. Unlike the sharp tips that characterize the usual form of Cu dendrites, the ends of both the trunk and branches were globules in the formed dendrites, indicating that a novel type of Cu dendrites was formed in this investigation. Although the macro structures of the particles were extremely varied, they had very similar micro structures because they were constructed by spherical grains. The Cu crystallites were randomly oriented in the dendrites and compact agglomerates of the Cu grains, while the disperse cauliflower-like particles showed (220) and (311) preferred orientation. This indicates that the applied current density affects not only the morphology of the particles, but also their crystal structure. The best performance, defined by the largest specific surface area and the smallest particle size, was by the galvanostatically produced powder consisting of disperse cauliflower-like particles.

AB  - Production of copper powders by the potentiostatic electrolysis under different hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction (XRD), particle size distribution (PSD), and by the determination of the specific surface area (SSA) of the formed powders. Depending on quantity of hydrogen generated during electrolysis, the two types of particles were formed: dendrites and cauliflower-like particles. The dendrites were formed without, while cauliflower-like particles with the quantity of evolved hydrogen enough to achieve strong effect on hydrodynamic conditions in the near-electrode layer. Although macro structure of the particles was very different, they showed similar micro structure. Namely, both types of the particles consisted of small agglomerates of approximately spherical Cu grains at the micro level. The existence of the spherical morphology was just responsible for random orientation of Cu crystallites in both types of particles. The SSA of cauliflower-like particles was more than two times larger than that of the dendrites, while their size was considerably smaller than that of the dendritic particles. In this way, the useful benefit of Cu powder formation in the conditions of vigorous hydrogen evolution is shown.

Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction (XRD), particle size distribution (PSD), and by the determination of the specific surface area (SSA) of the formed powders. Depending on quantity of hydrogen generated during electrolysis, the two types of particles were formed: dendrites and cauliflower-like particles. The dendrites were formed without, while cauliflower-like particles with the quantity of evolved hydrogen enough to achieve strong effect on hydrodynamic conditions in the near-electrode layer. Although macro structure of the particles was very different, they showed similar micro structure. Namely, both types of the particles consisted of small agglomerates of approximately spherical Cu grains at the micro level. The existence of the spherical morphology was just responsible for random orientation of Cu crystallites in both types of particles. The SSA of cauliflower-like particles was more than two times larger than that of the dendrites, while their size was considerably smaller than that of the dendritic particles. In this way, the useful benefit of Cu powder formation in the conditions of vigorous hydrogen evolution is shown.",

AB  - The morphologies of copper dendritic forms obtained in both potentiostatic and galvanostatic regimes of electrolysis with various amounts of the electricity were analyzed by the scanning electron microscopy (SEM) technique. Irrespective of amount of passed electricity, 3D (three dimensional) pine-like dendrites with sharp tips were formed in the potentiostatic regime of electrolysis. On the other hand, the amount of passed electricity had a strong effect on the shape of the 3D pine-like dendrites formed in the galvanostatic regime of electrolysis. Dendrites with sharp tips were formed with smaller amount of passed electricity, while dendrites with globular tips were formed with larger amounts. The change in the shape of the galvanostatically synthesized 3D pine-like dendrites was explained by comparison with copper deposits obtained potentiostatically at overpotentials that corresponded to the final overpotentials during galvanostatic regime of electrolysis for the analyzed amounts of electricity. Based on the similarity of the obtained morphologies at the macro level, it was concluded that the overpotential plays a crucial role in the formation of the electrolytically synthesized dendrites and that the controlled conditions of electrolysis could represent a suitable way for a synthesis of spherical Cu particles by electrolysis.

AB  - The magnesium oxide (MgO)/magnesium hydroxide (Mg(OH)2) in recent years have received
considerable attention as one of the nanomaterials intended for specific application. The interest in this material is standing from promising utilization in next generation solar cells, advanced catalysis, medicine, toxic waste remediation and similar. More advanced utilizations, however, require controlled surface morphology and composition of the oxy/hydroxide.
It is now common knowledge that electrodeposition technique provides a suitable way to obtain
materials of micro or nano scales in the desired forms. Additionally, shape and size of the deposited material can be conveniently controlled by the choice of parameters and regimes of electrolysis.
A novel approach to electrochemical synthesis of magnesium oxide/hydroxide meso - and
nanostructures on glassy carbon electrode from the melt made of magnesium nitrate hexahydrate melt at 100 °C have been considered. The electrodeposition of magnesium oxide/hydroxide commences in magnesium underpotential (UPD) and continues through the magnesium overpotential (OPD) region.
Chronoamperometric analysis showed that magnesium oxides/hydroxides syntheses taking part
simultaneously at various applied potentials are a result of reactions between magnesium cations and products of water and nitrate anions reduction processes. Chemical reactions responsible for direct formation of magnesium oxide observed are those of magnesium ions and oxygen ions, formed by nitrate reduction taking part in the close vicinity of the working electrode. The morphology of magnesium oxide/hydroxide obtained by galvanostatic regime were characterised using scanning electron microscopy (SEM) technique. Network of individual very thin needles were formed in both magnesium UPD and OPD region, as well as those grouped in flower-like aggregates in magnesium OPD regions, Fig.1.

AB  - The electrochemical deposition of the Fe-Ni alloy powders from citrate-sulfate containing electrolytes of different Ni/Fe ions concentration ratios at pH 4.5 was examined by the polarization measurements. All polarization curves have a similar shape and are characterized by the presence of two inflection points. The first inflection point reflects the beginning of alloy deposition, while the second one (˜) corresponds to the moment when the cathode reaction becomes determined by the rate of hydrogen bubbles formation. The potentials of Fe-Ni alloys deposition at all investigated Ni/Fe ratios are more positive than those for pure metal powders deposition. As the Ni/Fe ratio decreases, the polarization curves are placed at slightly more positive potentials. The morphology of electrodeposited powder particles was investigated using scanning electron microscopy (SEM). A common characteristic of all Fe-Ni alloy powders is the presence of cone shaped cavities. Powder particles electrodeposited at the ratio Ni/Fe = 9/1 are mainly consisted of nodules of either very flat surface or rough surface, with well defined crystals detected only on a few particles. With the decrease of the Ni/Fe ratio, the presence of well defined crystals on the nodule surface becomes more pronounced. In the powder with the highest amount of Fe (Ni/Fe = 1/3), the whole surface of all particles is covered with crystals of different shapes.

Prva prevojna tačka odgovara početku taloženja Fe-Ni legure, dok druga predstavlja momenat kada ukupna elektrohemijska reakcija postaje kontrolisana brzinom formiranja mehurova vodonika. Potencijali taloženja Fe-Ni legura pri svim ispitivanim odnosima Ni/Fe pozitivniji su od potencijala taloženja čistih metala, pri čemu se sa smanjenjem odnosa Ni/Fe polarizacione krive pomeraju ka malo pozitivnijim vrednostima potencijala. Morfologija čestica prahova ispitivana je korišćenjem skenirajuće elektronske mikroskopije (SEM). Zajednička karakteristika svih prahova Fe-Ni legura je prisustvo šupljina konusnog oblika. Čestice praha istaloženog pri odnosu Ni/Fe = 9/1 uglavnom su sastavljene od čvorića, glatke ili neravne površine, kod kojih se na pojedinim mestima mogu uočiti dobro definisani kristali. Sa smanjenjem odnosa Ni/Fe, prisustvo kristala na površini čvorića postaje sve izraženije, dok su kod praha sa najvećim sadržajem Fe (Ni/Fe = 1/3) na celoj površini čestica prisutni kristali različitog oblika.

AB  - The electro deposition of the Ni-Mo-O alloy powders from ammonium sulfate containing electrolytes of different Ni/Mo ions concentration ratios was investigated by the polarization measurements. In all electrolytes similar polarization curves were obtained, characterized by two inflection points Point A, the beginning of the electro deposition process and point B, a moment when the powder electro deposition is controlled by the hydrogen bubbles formation. The morphology of the electrodeposited Ni-Mo-O alloy powders was investigated using SEM. At Ni/Mo ratios higher or equal to 1/1 two types of particles were detected in the powder deposits: spongy-type particles (100 - 200 μm) with flat nodular surface and presence of cavities and agglomerates of similar dimensions characterized by the presence of cracks and cavities, with the nodular surface that is not flat, but is covered by the freshly formed dendrites. At Ni/Mo ratios of 1/3 the contribution of the amorphous-compact deposit is significant, while on top of this deposit rounded dendrite and compact outgrowths were detected.
AB  - Elektrohemijsko taloženje prahova Ni-Mo-O legura ispitivano je snimanjem polarizacionih dijagrama u sulfatno-amonijačnim elektrolitima pri različitim odnosima Ni/Mo. Sve polarizacione krive okarakterisane su prisustvom dve prelomne tačke (A i B) na dijagramu. Tačka A odgovara početku taloženja Ni-Mo-O legure, dok tačka B reflektuje momenat kada je ukupna elektrohemijska reakcija kontrolisana brzinom formiranja mehurova gasovitog vodonika pri čemu se sa povećanjem koncentracije MoO4 2- jona u elektrolitu potencijal početka taloženja (tačka A) pomera ka negativnijim vrednostima. Morfologija čestica prahova ispitivana je skenirajućom elektronskom mikroskopijom (SEM). Prahovi istaloženi na staklastom ugljeniku iz elektrolita sa Ni/Mo ≥ 1/1 okarakterisani su prisustvom dve vrste čestica: sunđeraste čestice veličine 100 - 200 μm relativno glatkih površina sa jasno izraženim rupama i aglomerati sličnih veličina na kojima su prisutne jasno izražene naprsline i rupe, čija površina nije glatka i pokriveni su novo stvorenim grozdovima dendritičnog taloga. Za čestice praha istaloženog iz elektrolita koji sadrži odnos jona Ni/Mo = 1/3 karakteristično je da je udeo kompaktnog taloga značajan u poređenju sa ostalim prahovima, na kome se mogu registrovati dva tipa loptastih izraslina: manje kompaktne izrasline sa jasno definisanim dendritima i znatno kompaktnije izrasline. Kod prahova istaloženih na elektrodi od Ni, pored vrsta čestica koje su registrovane pri taloženju prahova na elektrodi od staklastog ugljenika, može se videti da se deo kompaktnog taloga praktično sastoji iz slojevitih struktura koje su posledica favorizovanog epitaksijalnog rasta taloga na srodnim podlogama.

Tačka A odgovara početku taloženja Ni-Mo-O legure, dok tačka B reflektuje momenat kada je ukupna elektrohemijska reakcija kontrolisana brzinom formiranja mehurova gasovitog vodonika pri čemu se sa povećanjem koncentracije MoO4 2- jona u elektrolitu potencijal početka taloženja (tačka A) pomera ka negativnijim vrednostima. Morfologija čestica prahova ispitivana je skenirajućom elektronskom mikroskopijom (SEM). Prahovi istaloženi na staklastom ugljeniku iz elektrolita sa Ni/Mo ≥ 1/1 okarakterisani su prisustvom dve vrste čestica: sunđeraste čestice veličine 100 - 200 μm relativno glatkih površina sa jasno izraženim rupama i aglomerati sličnih veličina na kojima su prisutne jasno izražene naprsline i rupe, čija površina nije glatka i pokriveni su novo stvorenim grozdovima dendritičnog taloga. Za čestice praha istaloženog iz elektrolita koji sadrži odnos jona Ni/Mo = 1/3 karakteristično je da je udeo kompaktnog taloga značajan u poređenju sa ostalim prahovima, na kome se mogu registrovati dva tipa loptastih izraslina: manje kompaktne izrasline sa jasno definisanim dendritima i znatno kompaktnije izrasline. Kod prahova istaloženih na elektrodi od Ni, pored vrsta čestica koje su registrovane pri taloženju prahova na elektrodi od staklastog ugljenika, može se videti da se deo kompaktnog taloga praktično sastoji iz slojevitih struktura koje su posledica favorizovanog epitaksijalnog rasta taloga na srodnim podlogama.",
