AB  - The quest for sustainable biomaterials with excellent biocompatibility and tailorable
properties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high production
costs and the lack of bioactivity limit their market penetration. To address this, poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined with a bacterial pigment with strong
anticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. The
samples were produced in the form of films 115.6–118.8  m in thickness using the solvent casting
method. The effects of PG incorporation on the physical properties (morphology, biopolymer crystallinity
and thermal stability) and functionality of the obtained biomaterials were investigated. PG
has acted as a nucleating agent, in turn affecting the degree of crystallinity, thermal stability and
morphology of the films. All samples with PG had a more organized internal structure and higher
melting and degradation temperatures. The calculated degree of crystallinity of the PHBV copolymer
was 53%, while the PG1, PG3 and PG3 films had values of 64.0%, 63.9% and 69.2%, respectively.
Cytotoxicity studies have shown the excellent anticancer activity of films against HCT116 (colon
cancer) cells, thus advancing PHBV biomedical application potential.

AB  - One of the most popular alternative sources of energy are direct methanol fuel cells (DMFCs) with platinum-based catalysts due to their non-toxicity, reduced emissions of hazardous pollutants and high energy density. However, significant challenges of the scientific community related to Pt catalysts are the high cost, depletable resources and formation of poisoning species i.e. CO, during the methanol oxidation reaction. To reduce the amount of expensive Pt and susceptibility of Pt to poisoning species and simultaneously improve its catalytic performance, recent studies are focusing on the synthesis of Pt alloys in which a certain amount of platinum is replaced with less expensive metals such as Ru, Sn, Ni, Cu, Rh and Co. The usage of carbon (Vulcan XC-72R) for catalyst support enables high dispersion of metal, high surface area and good electrical conductivity improving overall performances of DMFCs. In this work, PtZn/C and PtSnZn/C catalysts were synthesized by the microwave-assisted polyol method. The structure and morphology of the catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TG) and X-ray diffraction (XRD) analysis. The activity and stability of synthesized catalysts for methanol oxidation in 0.5 M sulfuric acid were investigated. It was demonstrated that the activity of the platinum catalysts was improved thanks to the synergistic effects caused by the addition of different metals, such are bifunctional and electronic effects.

AB  - In order to achieve widespread application of fuel cell technology, the
development of an efficient and economical catalyst is a crucial step. Reducing the
diameter of catalyst particles, producing particles with a specific orientation surface,
and alloying noble metals with less expensive metals are possible approaches to
improve catalyst performance. This study will be focused on novel ways for creating
PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are
methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and were
supported on high surface area carbon Vulcan XC-72R material. The electrochemical
behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry,
chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine
the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission
electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were
used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the
benefits of microwave synthesis and carefully adjusted metal alloying.

AB  - Polymer electrolyte membrane fuel cells (PEMFCs) are pure electrochemical energy converters that are key components of energy sources for vehicles and for stationary and portable energy suppliers. Searching for a good catalyst for the ethanol oxidation reaction is one of the most significant issues in material science. To increase the economic potential of fuel cell technology, catalyst must be extremely active, stable, and inexpensive. Due to its high catalytic activity, structural and chemical stability, and widespread use in commercial fuel cells, platinum is still the material of choice for making cathodes. Although there is extensive continuing research to reduce the Pt concentration while keeping the high catalytic activity, its high cost remains a barrier to a wider adoption of fuel cell technology.Therefore, the potential for cost reduction lies in the optimization of the catalyst, i.e. obtaining the maximum catalytic efficiency with the lowest possible content of noble metals. The focus of this research will be on novel synthesis techniques for PtSnZn catalysts with better efficiency and durability for the ethanol oxidation reaction. This research demonstrates the potential of studying new PtSnZn catalytic materials as catalysts for the oxidation of ethanol. This study used the microwave assisted polyol technique to create PtZn and PtSnZn nanoparticles supported on high surface area carbon Vulcan XC-72R material. By using cyclic voltammetry, electro-oxidation of adsorbed CO, and the chronoamperometric method, the electrochemical behavior of synthesized catalysts was examined. X-ray diffractometry, transmission electron microscopy analysis and thermogravimetric analysis were applied to obtain the physicochemical properties of the catalyst. The advantages of microwave synthesis and carefully balanced metal alloying in the PtSnZn/C catalysts led to a high catalytic activity of the synthesized catalyst in the ethanol oxidation reaction compared to the Pt/C catalyst.

AB  - Tin dendrites found wide application in various industries.1 They can be obtained by both non-electrochemical and electrochemical methods of synthesis. In this study, they were produced by a galvanostatic regime of electrolysis from alkaline hydroxide solution at a current density of –3 mA cm–2, 1.5 times larger than the limiting diffusion current density, with an amount of the electricity of 200 and 400 mC. In the dependence of an amount of the passed electricity, Sn dendrites of various morphology and crystal orientation were obtained: the fern-like dendrites predominantly oriented in (220), (440) crystal planes are obtained with 200 mC and the spear-like and the dendrites with prismatic branches showing the strong (200),(400) preferred orientationwere obtained with 400 mC.
The strong correlation between morphology and structure of Sn dendrites is established and it can be explained by analysis of chronopotentiometry response obtained at the given current density and by morphological and structural analyses of Sn dendrites obtained by a potentiostatic regime at cathodic potentials corresponding to values attained after the passed amount of the electricity of 200 and 400 mC. The chronopotentiometry response after spent 200 mC was dominantly in the (–1600 –1740) mV vs. Ag/AgCl range, and the fern-like dendrites with the strong (220), (440) preferred orientation were obtained in this potential range. After spent 400 mC, the chronopotentiometry response was about –1200 mV vs. Ag/AgCl, and the spear-like and the dendrites with prismatic branches with the strong (200),(400) preferred orientationwere obtained at this cathodic potential.

AB  - This work highlights the potential for the synthesis of new PtSnZn catalysts with enhanced efficiency and durability for methanol oxidation reaction (MOR) in low-temperature fuel cells. In this research, PtZn and PtSnZn nanoparticles deposited on high surface area Vulcan XC-72R Carbon support were created by a microwave-assisted polyol method. The electrochemical performances of synthesized catalysts were analyzed by cyclic voltammetry and by the electrooxidation of adsorbed CO and the chronoamperometric method. The physicochemical properties of obtained catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TGA) analysis, energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD). The obtained findings showed the successful synthesis of platinum-based catalysts. It was established that PtSnZn/C and PtZn/C catalysts have high electrocatalytic performance in methanol oxidation reactions. Catalysts stability tests were obtained by chronoamperometry. Stability tests also confirmed decreased poisoning and indicated improved stability and better tolerance to CO-like intermediate species. According to activity and stability measurements, the PtSnZn/C catalyst possesses the best electrochemical properties for the methanol oxidation reaction. The observed great electrocatalytic activity in the methanol oxidation reaction of synthesized catalysts can be attributed to the beneficial effects of microwave synthesis and the well-balanced addition of alloying metals in PtSnZn/C catalysts.

AB  - The influence of chronopotentiometry response on the morphology and structure of galvanostatically synthesized tin dendritic
particles has been investigated. Sn dendrites were electrodeposited at the current density 1.5 times larger than the limiting diffusion
current density (− 3 mA cm−
2) with various amounts of the electricity (200 and 400 mC), and the obtained morphology
and structure of the particles were characterized by SEM and XRD techniques, respectively. The strong effect of the amount
of spent electricity on the morphology and structure of the particles was observed, and it is explained by morphological and
structural analysis of Sn particles produced potentiostatically at various cathodic potentials selected to be in line with the
recorded chronopotentiometry response. The strong correlation among chronopotentiometry response, morphology, and
structure of the Sn dendrites was established. The spear-like and the dendrites with prismatic branches possessed the strong
(200),(400) preferred orientation, and they were obtained with a chronopotentiometry response of about − 1200 mV vs. Ag/
AgCl. The chronopotentiometry responses in the − 1210 ÷ − 1740 mV vs. Ag/AgCl range caused a formation of the fern-like
dendrites with the strong (220),(440) preferred orientation. Based on the obtained results, it follows that the chronopotentiometry
analysis represents good diagnostic criteria for obtaining Sn powder particles of desired morphology and structure.

AB  - Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for metallic nanoparticle synthesis and appeared as suitable alternative for widely used carbon based materials. Following the idea to replace commonly used carbon based materials for platinum supports with the green and sustainable one, BNC appeared as an excellent candidate. Herein, microwave assisted synthesis has been reported for the first time for platinum nanoparticles supported on BNC as green material. Bacterial nanocelullose-platinum catalyst, Pt/BNC, was investigated by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), atomic force microscopy (AFM), X-ray diffractometry (XRD) and transmission-electron microscopy (TEM) analysis. The obtained results confirmed successful synthesis of new Pt-based catalyst. It was found that Pt/BNC catalyst has high electrocatalytic performance in methanol oxidation reaction. Green/sustainable catalytic system is highly desirable and provided by the elegant microwave assisted synthesis of Pt/BNC will pave the way for a larger scale application and expedite the market penetration of such fuel cells.

AB  - The main objective of this work was to prepare new platinum supported catalyst on BNC/PVA composite as nanoparticles carrier, designed for electrocatalytic applications. For that purpose, BNC/Pt suspension was mixed with 1 wt% PVA solution and BNC/PVA/Pt catalyst in the form of film was successfully synthesized. The structure and thermal properties of catalyst were characterized by ATR-FTIR and TG analysis, respectively, while its crystallinity was investigated 
by XRD analysis. Electrocatalytic potential of BNC/PVA/Pt catalyst was tested in methanol 
oxidation reaction. Remarkable catalytic activity of new Pt based catalyst was confirmed. The 
obtained results for catalyst activity was comparable to those obtained for preferentially used 
carbon based Pt supports pointing that BNC based composited can be considered as great 
substitution of carbon based materials with the green one.

AB  - Tin dendrites were synthesized via electrochemical route from the alkaline electrolyte applying both 
potentiostatic and galvanostatic regimes of the electrodeposition. Various both cathodic potentials 
and amounts of the passed electricity were used for Sn electrodeposition in the potentiostatic regime. Morphology and structure of synthesized tin dendritic particles were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques, respectively. Depending on the applied cathodic potential, morphology of tin dendrites changed from the needle-like and the spear-like to very ramified dendrites of various shape. The branchy Sn dendrites were of two dimensional (2D) shape constructed from stalk and branches developed from it (primary (P) branches), classifying them into 2D(P) type according to Wranglen`s definition of a dendrite. The XRD analysis of produced tin particles showed that the needle-like and the spear-like dendrites represented monocrystals (200) orientation, while Sn crystallites in the potenciostatically obtained 2D(P) dendrites were predominately oriented in (440) plane. Morphology of tin particles was also correlated with polarization characteristics for this system, confirming belonging tin to the group of the normal metals, characterized by the high values of the exchange current density and overpotential for hydrogen evolution reaction, and by the low melting point.
AB  - Dendriti kalaja su bili sintetizovani elektrohemijskim putem iz alkalnog elektrolita primenjujući i potenciostatski i galvanostatski režim elektrohemijskog taloženja. Elektrohemijsko taloženje kalaja u potenciostatskom režimu je vršeno na različitim katodnim potencijalima i sa različitim količinama naelektrisanja. Morfologija i struktura sintetizovanih dendritičnih čestica kalaja su okarakterisane tehnikom skenirajuće elektronske mikroskopije (SEM) i rentgensko difrakcionom analizom. U 
zavisnosti od primenjenog katodnog potencijala, morfologija dendrita kalaja se menjala od igličastih i dendrita nalik koplju do veoma razgranatih dendrita. Veoma razgranati kalajni dendriti su bili dvodimenzionalnog (2D) oblika izgrađeni od stabla i grana razvijenih iz stabla (primarne (P) grane), klasifikujući ih u 2D(P) tip prema Vranglenovoj definiciji dendrita. Rentgensko-difrakciona analiza je pokazala da igličasti i dendriti nalik koplju su predstavljali monokristale (200) orijentacije, dok su 
kristaliti kalaja u potenciostatski dobijenim 2D(P) dendritima bili predominantno orijentisani u (440) ravni. Morfologija čestica kalaja je bila takođe korelisana sa polarizacionim arakteristikama za ovaj sistem, potvrđujući pripadnost kalaja grupi normalnih metala okarakterisanih visokim vrednostima gustine struje izmene i prenapetosti za reakciju izdvajanja vodonika, i niskom tačkom topljenja.

AB  - The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte
has been investigated. Morphology and structure of Sn dendrites produced applying both potentiostatic and galvanostatic regimes of the electrolysis are characterized by SEM and XRD, respectively. Depending on the applied cathodic potentials, three types of Sn dendrites were obtained: (a) needle like and spear-like, (b) fern-like, and (c) stem-like dendrites. The very branchy dendrites with branches of the prismatic shape obtained by the galvanostatic regime of electrolysis represented a
novel type of Sn dendrites, not previously reported in the literature. To explain the formation of
various dendritic forms, correlation with the polarization characteristics for this electrodeposition
system is considered. The needle-like and the spear-like dendrites represented monocrystals of
(200),(400) preferred orientation, the fern-like dendrites exhibited the predominant (220),(440) preferred
orientation, while in the stem-like particles Sn crystallites were oriented to a greater extent in
the (440) crystal plane than in other planes. The galvanostatically synthesized Sn particles possessed the strong (200),(400) preferred orientation. The strong influence of parameters and regimes of
electrodeposition on structural characteristics of Sn dendrites is explained by the fundamental laws
of electrocrystallization taking into consideration the concept of slow-growing and fast-growing
crystal planes.

AB  - Catalysts support is essential for nanostructured noble metal catalysts activity and stability since that interaction between the metal particle and the support can affect metal particle size and dispersion. Over the last few decades, the most popular catalysts supports are carbon based materials: Vulcan XC-72 carbon black (CB), multi-walled carbon nanotubes (MWCNTs) and graphene. However, their cost-effective production remains a challenge since most of these materials are obtained by pyrolysis of coal or petroleum. Not less negligible is their negative impact on the environment during synthesis because these processes include release of carbon dioxide and other harmful organic products into the atmosphere. Applications of bacterial nanocelluloses as a catalyst support has attracted a great attention since it can be easily synthesized and is an inexpensive, biodegradable, sustainable and green material. Bacterial nanocellulose (BNC) was produced utilizing the Komagataeibacter medellinensis ID13488 strain. Stable Pt nanoparticles supported on BNC (Pt/BNC) have been synthetized from a precursor solution of H2PtCl6 by microwave assisted polyol procedure. Catalytic activity was tested for methanol oxidation reaction in sulfuric acid solution. The Fourier transform infrared spectroscopy was used to confirm the structure of bacterial nanocellulose as well as after synthesis of Pt-BNC catalyst. Coupled differential scanning calorimetry (DSC) / thermogravimetric (TG) analysis revealed no loss of platinum during synthesis process. XRD analysis showed characteristic peaks for fcc crystalline structure of Pt/BNC and particle size of 1,7 nm. The activity of the Pt/BNC, catalyst for methanol oxidation was evaluated from potentiodynamic measurements in 0.5 M H2SO4 + 0.5 M CH3OH solution. The results obtained indicate enhanced catalytic activities for methanol oxidation reaction.
AB  - Podloge katalizatora imaju veoma važnu ulogu tokom sinteze katalizatora sa plemenitim metalima obzirom da od njihove interakcije sa metalom zavisi veličina čestica i njihova disperzija tokom procesa sinteze. Tokom poslednjih nekoliko decenija kao najčešće korišćene podloge za platinske katalizatore su korišćene podloge na bazi uglljenika: ugalj razvijene površine (Vulcan XC), ugljenične nanotube ili grafen. Međutim, proces dobijanja ovih materijala ima visoke cene zbog toga što se za njihovo dobijanje koriste procesi pirolize uglja ili nafte. Ništa manje zanemarljiv je i negativan uticaj ovih procesa na okolinu pošto procesi sinteze uključuju oslobađanje ugljen dioksida i drugih štetnih materija u atmosferu. Primena bakterijskih nanoceluloza kao nosača katalizatora privukla je veliku pažnju jer se mogu lako sintetizovati i predstavljaju jeftin, biorazgradiv, održiv i zeleni materijal. Bakterijska nanoceluloza (BNC) proizvedena je upotrebom soja Komagataeibacter medellinensis ID13488. Stabilne Pt nanočestice suspendovane na BNC (Pt/BNC) sintetizovane su iz prekursorskog H2PtCl6 rastvora poliol postupkom uz pomoć mikrotalasne pećnice. Ispitivana je katalitička aktivnost reakcije oksidacije metanola u rastvoru sumporne kiseline. Infracrvena spektroskopija Fourierove transformacije je korišćena za potvrdu strukture same bakterijske nanoceluloze, kao i nakon sinteze Pt-BNC katalizatora. Diferencijalna skenirajuća kalorimetrija (DSC) / termogravimetrijska (TG) analiza nije otkrila gubitak platine tokom procesa sinteze. XRD analiza pokazala je karakteristične vrhove za fcc kristalnu strukturu Pt/BNC i veličinu čestica od 1,7 nm.

AB  - In this review paper, morphologies of metal powders produced by the constant (potentiostatic
and galvanostatic) regimes of electrolysis from aqueous electrolytes are correlated with
their crystal structure at the semiquantitative level. The main parameters affecting the shape of
powder particles are the exchange current density (rate of electrochemical process) and overpotential for hydrogen evolution reaction. Depending on them, various shapes of dendrites (the needles, the two-dimensional (2D) fern-like, and the three-dimensional (3D) pine-like dendrites), and the particles formed under vigorous hydrogen evolution (cauliflower-like and spongy-like particles) are produced by these regimes of electrolysis. By decreasing the exchange current density value, the crystal structure of the powder particles is changed from the strong (111) preferred orientation obtained for the needle-like (silver) and the 2D (lead) dendrites to the randomly orientated crystallites in particles with the spherical morphology (the 3D dendrites and the cauliflower-like and the spongylike particles). The formation of metal powders by molten salt electrolysis and by electrolysis in deep eutectic solvents (DESs) and the crystallographic aspects of dendritic growth are also mentioned in this review.

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  - Nickel−cobalt (Ni−Co) alloy powders were produced galvanostatically by using sulphate electrolytes with
various ratios of Ni2+/Co2+ (mole ratios). The morphology, phase structure, chemical composition and magnetic
properties were examined by scanning electron microscope (SEM), X-ray diffractometer (XRD), atomic emission
spectrometer (AES), and SQUID-based magnetometer, respectively. Morphology of the particles changed from
cauliflower-like and dendritic to coral-like and spongy-like ones with increasing Ni2+/Co2+ ratio from 0.25 to 4.0. XRD
analysis of the Ni−Co powders revealed that the decrease of Ni2+/Co2+ ratios (the increase of Co content) caused a
change of structure from face centered cubic (FCC) obtained for the ratios of 4.0, 1.5 and 0.67 to a mixture of FCC and
hexagonal closed-packed (HCP) phases for the ratio of 0.25. The increasing content of nickel led to change of
mechanism of electrolysis from irregular (up to ~40 wt.% Ni in the electrolytes) to close to equilibrium (between
~40 and 60 wt.% Ni in the electrolytes) and anomalous co-deposition (over 60 wt.% Ni in the electrolytes) type. All of
the obtained Ni−Co alloy samples behaved as soft magnetic materials while their magnetic parameters showed
immediate composition dependence since both coercivity and saturation magnetization almost linearly increased with
increase of the Co content.

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  - The biological quality and chemical composition of alloys used in dental practice change during heat treatment.
Often the residues of the previous cast are not disposed of but are reused and recycled until consumed. Thus, manufactured dental restorations have modified biological quality and chemical composition, and compromised biocompatibility. The aim of this study was to investigate the influence of repeated casting on the cytotoxicity of the silver-palladium (Ag-Pd) alloy. Our results showed that repeated casting of the Ag-Pd dental alloy affected its biocompatibility by promoting toxicity against transformed fibroblasts in a contact-independent manner. A strong decrease in cell proliferation, induction of senescence and massive cell death were observed in cultures exposed only to a medium previously incubated with dental alloy samples. The obtained data indicated that toxicity mediated by the accumulation of the Ag, Pd, Cu and Zn cations released from the Ag-Pd material was enhanced by recasting. The induction of cell senescence and subsequent apoptotic
and necrotic death were accompanied by amplified intracellular production of reactive oxygen and nitrogen species, suggesting their involvement in the cell destruction process. Therefore, compromised biocompatibility after recasting with the Ag-Pd alloy can be the cause of serious local cell destruction, as observed in clinical practice.

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.

AB  - Lead and nickel powder particles were produced by the processes of electrolysis and characterized by scanning electron microscope (SEM). The X-ray diffraction (XRD) analysis of the produced particles was done. Morphologies of Pb and Ni particles were correlated with their crystal structure at the semi quantitative level by determination of 'Texture Coefficients' (TC) and 'Relative Texture Coefficient' (RTC). The two dimensional (2D) dendritic particles of lead of different degree of ramification were obtained by the potentiostatic regime of electrolysis from the nitrate, acetate and hydroxide electrolyte. The spongy-like particles of nickel constructed from holes formed of the detached hydrogen bubbles and surrounded by cauliflower-like agglomerates of approximately spherical grains (the honeycomb-like structure) were obtained by the galvanostatic regime of electrolysis from the chloride electrolyte. Although crystallites were dominantly oriented in the (111) plane in both Pb and Ni particles, analysis of the XRD data showed different preferred orientation of the formed particles. All types of Pb dendritic particles showed the strong (111) preferred orientation, while crystallites of Ni in the spongy-like particles were almost random oriented. The obtained results were discussed following Winand's classification of metals on the normal, intermediate and inert metals based on their values of the exchange current density, melting point and overpotential for hydrogen evolution reaction.

AB  - 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 analysis of the produced particles. The needle-like and fern-like dendrites were formed from the nitrate electrolyte at overpotentials inside and outside plateaus of the limiting diffusion current density, respectively. The three-dimensional pine-like dendrites constructed from approximately spherical grains were formed from the ammonium electrolyte at overpotentials both inside and outside plateaus of the limiting diffusion current density. The morphology of silver dendrites was correlated with their crystal structure at the semi quantiative level. The change of crystal orientation from the strong (111) preferred orientation for the needle-like dendrites to almost randomly orientied spherical grains in the pine-like dendrites obtained at the overpotential outside the plateau of the limiting diffusion current density was observed. This trend in change of crystal orientation and morphology of Ag nanostructures was accompanied by considerable increase of the specific surface area (SSA) of the produced powders. The average crystallite sizes were in the range of 38-50 nm, proving nanostructural character of the formed Ag particles.

AB  - Silver powder particles of nanostructured characteristics were produced by the galvanostatic regime of electrolysis and compared with those obtained by chemical reduction with hydrazine. 
Morphology of all types of powder particles was examined by the technique of scanning electron 
microscopy (SEM), while crystallographic characteristics were examined by the X-ray diffraction 
(XRD) analysis of the obtained particles. Morphology of the electrochemically produced powder 
particles strongly depended on the type of used electrolyte. The irregular crystals and the needle-like dendrites were predominately formed from the nitrate (acid) electrolyte. On the other hand, the 
3D pine-like dendrites very similar to Cu dendrites [1] were formed by the electrodeposition from 
the ammonium (alcali) electrolyte. Simultaneously, the particles of spherical shape were formed by 
chemical reduction with hydrazine. The difference in morphology of electrochemically produced 
Ag powders can be explained by different rate of the electrochemical process by which they are 
formed. Namely, the ammonium electrolyte belongs to the group of the complex electrolyte and 
formation of this complex lowers the exchange current density for Ag causing a transfer of Ag from 
the group of the normal metals (metals with the high values of the exchange current density) to the 
group of the intermediate metals (metals with the medium values of the exchange current density). 
Irrespective of the way of preparation of Ag powder, Ag crystallites in all types of powder particles 
were predominantly oriented in the (111) plane. Formation of powder particles of the different shape with the strong (111) preferred orientation was discussed and explained by the consideration of the general characteristics of the growth of a crystal in the crystallization and 
electrocrystallization processes. Analogy between these two types of processes was made and discussed.
