AB  - In this work, plane tree seed-based activated carbons were characterized in detail for a variety of applications. The particularly important area of application would be in the artificial photosynthesis. After carbonization process of biomass precursor at 650°C, the resulting preliminary activated carbons were activated at various temperatures. The activated carbons were characterized by oxygen functionalities (a particularly important role has ester oxygen groups) which provide a unique microstructure. The chemical compositions of as-prepared activated carbons were analyzed through Fourier transform infrared and Raman spectra as well as gas chromatography–mass spectroscopy analysis, while morphology was observed by scanning electron microscopy analysis. Applied analysis showed that detected graphite mainly becomes uniformly nanocrystalline system. The current study also explored the applicability of carbon material obtained from plane tree seed as a potential gaseous adsorbent. The characterization showed that the tested material contains both mesopores and micropores, and this should be advantageous for the gas sorption process, since mesopores may provide low-resistant pathways for the diffusion of CO2 molecules, while the micropores are the most suitable for trapping of CO2. The sorption process analysis (including adsorption/desorption isotherms behavior) shows indication that the rate-limiting step of CO2 adsorption onto activated carbon is probably governed by diffusion-controlled process, especially at temperatures below 850°C.

AB  - The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) would allow creation of highly porous and spatially distinct ordered bio-SiC ceramics. The results of carbonization experiments at several operating temperatures and activation of carbons with multiple-cycle treatments TEOS clearly showed the possibility of obtaining SiC nano-structures, after performing the carbothermal reduction at 1400 °C. The increase in the activation temperature and the duration time starts the development of the SiC particles inside the porous structure. The XRPD analysis showed that the major SiC polytype has cubic SiC (β-SiC) structure and remainder is hexagonal SiC polytypic (α-SiC) structure. It was established that the carbons obtained from carbonization of the Platanus orientalis L. plane tree fruit (PTF) precursor and activated at 850 °C with longer holding times (1 and 2 h) exhibit β-SiC (cubic) nano-wires. A possible nano-wires increment mechanism was suggested. The obtained results represent significant contribution in understanding the process as well as the main characteristics of SiC nano-materials and their possible applications.

AB  - Five NiO/TiO2 materials with a different mass ratiо оf NiO tо TiO2 (3.3, 6.7, 16.3, 23.7, and 36.8%) were synthesized by wet impregnation process and characterized by DR UV-vis, scanning electrоn micrоscоpe, transmissiоn electrоn micrоscоpy, X-ray diffractiоn methоd, N2 physisorption, and temperature-programmed reduction. The characterizatiоn confirmed the existence of nano-sized cubic NiO on the commercial TiО2. The оbserved interactiоn between TiO2 and NiО phases confirmed that the оbtained material dоes nоt constitute a physical mixture оf twо species. The photocatalytic hydrоgen generatiоn efficiency [mоnitored by gas chromatography–thermal conductivity detector (GC-TCD)] of these materials from methanol-water mixtures under simulated solar radiation and artificial UV radiation was investigated. For some synthesized NiO/TiO2 materials, higher photocatalytic efficiency was found compared with the commercial TiO2 Degussa P25 catalyst. Also, the obtained results showed that 0.125 g L−1 of 6.7%NiO/TiO2 and 5% (v/v) of methanol were the optimal operating parameters.

AB  - Hydrogen evolution reaction (HER) was explored on tri-metallic Rh"Pd/Au(poly) and bimetallic Pd/Au(poly) and Rh/Au(poly) electrodes in alkaline solution. Electrodes were prepared by the spontaneous deposition of either Pd or Rh and by co-deposition of both Rh and Pd on polycrystalline gold electrode. Characterization of modified electrodes was performed by cyclic voltammetry in alkaline solution, while additional information about phase analysis, chemical composition and surface morphology of tai-metallic Rh"Pd/Au(poly) electrode were acquired using X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy and atomic force microscopy. Investigations of HER catalysis have shown that the activity of tri-metallic Rh Pd/Au(poly) electrode exceeds the activities of both Pd/Au(poly) and Rh/Au(poly) electrodes, meaning that the synergism between co-deposited Pd and Rh islands is achieved. Moreover, Rh"Pd/Au(poly) electrode showed significant approach to the activities of bulk Pd and Rh electrodes for HER, especially when taking into account low activity of bare Au substrate. Synergistic effect of co-deposited Pd and Rh islands is a consequence of the strong electronic interaction between three metals in a close contact, which promotes the activity for HER by lowering the adsorption energy of Hads intermediate.

AB  - Introduction: The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. The aim of the study was to compare the retrograde obturation quality of the following materials: calcium silicate (Biodentine; Septodont, Saint-Maur-des-Fosses, France), mineral trioxide aggregate (MTA+; Cerkamed Company, Stalowa Wola, Poland), and glass ionomer cement (Fuji IX; GC Corporation, Tokyo, Japan). Methods: Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. Cements' porosity was determined using mercury intrusion porosimetry and micro computed tomographic (mu CT) imaging. Extracted upper human incisors were retrofilled, and mu CT analysis was applied to calculate the volume of the gap between the retrograde filling material and root canal dentin. Experiments were performed before and after soaking the materials in simulated body fluid (SBF). Results: No statistically significant differences were found among the contact angles of the studied materials after being soaked in SBF. The material with the lowest nanoporosity (Fuji IX: 2.99% and 4.17% before and after SBF, respectively) showed the highest values of microporosity (4.2% and 3.1% before and after SBF, respectively). Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 +/- 30] x 10(-3) mm(3)). Conclusions: Biodentine and MTA possess certain advantages over Fuji IX for hermetic obturation of retrograde root canals. Biodentine shows a tendency toward the lowest marginal gap at the cement-to-dentin interface.

abstract = "Introduction: The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. The aim of the study was to compare the retrograde obturation quality of the following materials: calcium silicate (Biodentine; Septodont, Saint-Maur-des-Fosses, France), mineral trioxide aggregate (MTA+; Cerkamed Company, Stalowa Wola, Poland), and glass ionomer cement (Fuji IX; GC Corporation, Tokyo, Japan). Methods: Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. Cements' porosity was determined using mercury intrusion porosimetry and micro computed tomographic (mu CT) imaging. Extracted upper human incisors were retrofilled, and mu CT analysis was applied to calculate the volume of the gap between the retrograde filling material and root canal dentin. Experiments were performed before and after soaking the materials in simulated body fluid (SBF). Results: No statistically significant differences were found among the contact angles of the studied materials after being soaked in SBF. The material with the lowest nanoporosity (Fuji IX: 2.99% and 4.17% before and after SBF, respectively) showed the highest values of microporosity (4.2% and 3.1% before and after SBF, respectively). Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 +/- 30] x 10(-3) mm(3)).

AB  - Hydrogen evolution reaction (HER) was investigated in alkaline solution on tri-metallic Rh"Pd/Pt(poly) electrode, prepared by spontaneous deposition of Rh on top of Pd/Pt(poly) electrode with intermediate Pd coverage of 35%. Characterization of tri-metallic catalyst was performed by electrochemical methods of cyclic voltammetry and CO stripping voltammetry, while its activity for HER was tested by linear sweep voltammetry in 0.1 M NaOH. Rh"Pd/Pt(poly) catalyst has shown superior catalytic activity for HER with respect to initial Pt(poly) and both corresponding bimetallic Pd/Pt(poly) and Rh/Pt(poly) electrodes. This was explained by a strong synergistic electronic interaction between three metals in close contact induced at a number of different active sites across the surface of tri-metallic catalyst, which results with lowering of the binding energy for the adsorption of H intermediate species.

AB  - Iridium nanoislands are spontaneously deposited on Au(111) from (1 mMIrCl(3) center dot xH(2)O + 0.5 MH2SO4) depositing solution. Atomic Force Microscopy images of the obtained Ir/Au(111) bimetallic surfaces show that gold surface is fully covered with nanosized Ir islands after only 3 min of deposition.

AB  - Rh/Au(100) and Rh/Au(111) electrodes with Rh coverage below a monolayer are prepared by a spontaneous deposition method. Electrodes are characterized by AFM and XPS. Hydrogen evolution reaction (HER) is studied by linear sweep voltammetry in 0.1 M HClO4 solution. Results for gold single crystals with 50% Rh coverage, which have shown the best catalytic activity for HER are presented in this work. Enhanced catalytic activity of such bimetallic electrodes compared to the ones with higher Rh coverage is ascribed to the presence of smaller Rh islands, which provide suitable active surface sites. Rather strong electronic interaction between Rh deposit and gold substrates, which is manifested by the upshift of Rh3d5/2 photoelectron line, also contributes to their activity. Structural effect is manifested through a higher activity of 50% Rh/Au(111) than 50% Rh/Au(100), which is consistent with the difference in activity of respective bare gold single crystals.

AB  - Polycrystalline Pd electrode, Pd(poly), is modified by Ru nanoislands using spontaneous deposition method. Coverage of Pd(poly) electrode with the deposited Ru are approx. 20, 30 and 50% as estimated from phase atomic force microscopy images. The oxidation state of Pd substrate and the deposited Ru is determined by X-ray spectroscopy (XPS). Electrocatalytic activity of obtained Ru/Pd(poly) bimetallic electrodes is tested towards methanol oxidation in alkaline medium. Cyclic voltammetry and chronoamperometry experiments show the enhanced activity of Ru/Pd(poly) electrodes towards methanol electrooxidation with respect to bare Pd(poly).

AB  - Nanostructured nickel thin films were deposited on glass using glancing angle deposition (GLAD) technique. Cross-sectional field emission scanning electron microscopy images have shown that obtained Ni thin films consist of vertical, tilted or zigzag nano-scaled columns, while X-ray diffraction have shown that (111) orientation prevailed. X-ray photoelectron spectroscopy revealed that apart from metallic nickel, NiO and Ni(OH)(2) were also present in lower amount. Cyclic voltammetry in alkaline solution has shown that hydrogen evolution reaction (HER) was significantly catalyzed on all columnar nanostructures compared to Ni(poly). This was ascribed to the high electroactive surface area (EASA) of porous nickel columns. EASAs for vertical, tilted and zigzag Ni thin layers were higher 32, 25.3, and 24.9 times, respectively, than their geommetric areas. Accordingly, Ni thin films with vertical columns have shown the highest activity for HER.

AB  - Bone is a remarkable biological nanocomposite material showing peculiar hierarchical organization from smaller (nano, micro) to larger (macro) length scales. Increased material porosity is considered as the main feature of fragile bone at larger length-scales. However, there is a shortage of quantitative information on bone porosity at smaller length-scales, as well as on the distribution of pore sizes in healthy vs. fragile bone. Therefore, here we investigated how healthy and fragile bones differ in pore volume and pore size distribution patterns, considering a wide range of mostly neglected pore sizes from nano to micron-length scales (7.5 to 15000 nm). Cortical bone specimens from four young healthy women (age: 35 +/- 6 years) and five women with bone fracture (age: 82 +/- 5 years) were analyzed by mercury porosimetry. Our findings showed that, surprisingly, fragile bone demonstrated lower pore volume at the measured scales. Furtnermore, pore size distribution showed differential patterns between healthy and fragile bones, where healthy bone showed especially high proportion of pores between 200 and 15000 nm. Therefore, although fragile bones are known for increased porosity at macroscopic level and level of tens or hundreds of microns as firmly established in the literature, our study with a unique assessment range of nano-to micron-sized pores reveal that osteoporosis does not imply increased porosity at all length scales. Our thorough assessment of bone porosity reveals a specific distribution of porosities at smaller length-scales and contributes to proper understanding of bone structure which is important for designing new biomimetic bone substitute materials.

abstract = "Bone is a remarkable biological nanocomposite material showing peculiar hierarchical organization from smaller (nano, micro) to larger (macro) length scales. Increased material porosity is considered as the main feature of fragile bone at larger length-scales. However, there is a shortage of quantitative information on bone porosity at smaller length-scales, as well as on the distribution of pore sizes in healthy vs. fragile bone. Therefore, here we investigated how healthy and fragile bones differ in pore volume and pore size distribution patterns, considering a wide range of mostly neglected pore sizes from nano to micron-length scales (7.5 to 15000 nm). Cortical bone specimens from four young healthy women (age: 35 +/- 6 years) and five women with bone fracture (age: 82 +/- 5 years) were analyzed by mercury porosimetry. Our findings showed that, surprisingly, fragile bone demonstrated lower pore volume at the measured scales. Furtnermore, pore size distribution showed differential patterns between healthy and fragile bones, where healthy bone showed especially high proportion of pores between 200 and 15000 nm. Therefore, although fragile bones are known for increased porosity at macroscopic level and level of tens or hundreds of microns as firmly established in the literature, our study with a unique assessment range of nano-to micron-sized pores reveal that osteoporosis does not imply increased porosity at all length scales.

AB  - We have studied processes of gold ion implantation in polyethylene (PE) by theoretical chemistry methods. Car-Parrinello molecular dynamics (CPMD) simulations of collisions and following chemical kinetics considerations lead to the conclusion that chemical bonds between gold atoms and PE chains are formed. We have identified and characterized by a DFT method various stable structures with C-Au, C-Au-C, C-Au-H and C-Au center dot center dot center dot H-2 types of chemical bonds. The binding energies (BE) of C-Au bonds are as high as 227 kJ mol(-1) and the bond analysis reveals a covalent bonding character. For the experimental detection of these structures in gold implanted PE, we predicted characteristic infra-red (IR) frequencies. The C-Au stretching vibrational modes lie around 500 cm(-1). Other characteristic frequencies lie in a band between 730 cm(-1) and 1500 cm(-1).

AB  - Catalytic properties of electrochemically activated polycrystalline gold, Au(poly), modified by spontaneously deposited palladium nanoislands with the coverage below a monolayer were examined for the oxygen reduction reaction (ORR) in alkaline solution using the rotating disc electrode (RDE) technique. Atomic force microscopy (AFM) images have shown that the coverage of randomly distributed nanosized Pd islands ranged from 18% to 77%. Cyclic voltammetry characterization involved hydrogen adsorption/desorption on the deposited Pd islands, as well as their oxidation/reduction at more positive potentials. RDE measurements have shown that, although ORR on Au(poly) proceeds partly through 4e-reduction pathway, in the presence of Pd islands it turns completely to 4e-pathway, exceeding the activity of bare Pd(poly). Among different Pd/Au(poly) nanostructures, the ones with Pd coverage of 18% and 30% have shown the highest activity for ORR in alkaline solution.

AB  - Activated carbon was prepared using plane tree seed as a cheap and renewable raw material. The samples were prepared by carbonization under N-2 atmosphere up to 850 degrees C, and activation in CO2 atmosphere at different both temperatures (750 and 850 degrees C) and times of activation (0.3,1 and 2 h). The influence of activation parameters on physicochemical properties was studied by XRPD, Raman spectroscopy, FTIR, N-2 physisorption, SEM and electrochemical methods. The pore structure was correlated to the specific capacitance and the amount of hydrogen stored, in alkaline, neutral and acidic electrolyte solution. The relationship of asymmetrical shape of CV curves with the porosity of samples has served to better understand some unclear issues related to the complex mechanism of charge storage. The sample activated at 850 degrees C for 2 h displayed the best behavior. At a high scan rate of 300 mV s(-1), its capacitance, amounted to similar to 26.8 mu F cm(-2) 19.69 mu F cm(-2) and 25.8 mu Fcm(-2) in KOH, Na2SO4, and H2SO4 solutions, respectively.

AB  - Bimetallic electrodes prepared by Rh nanoislands spontaneously deposited on polycrystalline palladium, Pd(poly), at submonolayer coverage were explored for ethanol oxidation in alkaline media. Characterization of obtained Rh/Pd(poly) nanostructures was performed ex situ by AFM imaging and by X-ray photoelectron spectroscopy. In situ characterization of the obtained electrodes and subsequent ethanol oxidation measurements were performed by cyclic voltammetry in 0.1 M KOH. Palladium surface with 50% Rh coverage exhibited the highest catalytic activity for ethanol oxidation in alkaline media. The origin of the enhanced catalysis of Rh/Pd(poly) surfaces with respect to bare Pd was explained by the electronic effect. Possible reaction pathways for ethanol oxidation were discussed taking into account the activity of obtained bimetallic electrodes for the oxidation of CO and acetaldehyde, as the most probable reaction intermediates.

AB  - Catalytic properties of polycrystalline gold, Au(poly), were examined for the oxygen reduction reaction in alkaline solution using the rotating disc electrode technique. On electrochemically prepared Au(poly), oxygen reduction proceeds partly through 4e-reaction pathway resembling the activity of bare Au(100) in alkaline solution. Electrochemical behavior of such Au(100)-like polycrystalline gold electrode was compared with bare Au(100) surface, as well as with stepped Au(210)=Au[2(100)x(110)] and Au(533)=Au[4(111)x(100)] surfaces. It is shown that polycrystalline gold electrode behaved in a similar manner as stepped Au[n(111)x(100)] surfaces, meaning that the enrichment in (111)x(100) steps, rather than in (100) orientation is responsible for a partial 4e-reaction pathway in alkaline solution.

AB  - Nanostructures of noble metals (Pt and Ag) on carbon support were prepared from fructose and solution of the Nobel metal salts (H2PtCl6 x 6H2O or AgNO3) under hydrothermal conditions. Commercial fructose (C6H12O6) acts as the carbon source and reducing agent and noble metal salts is a source of the metal to be incorporated in the new formed carbon material structure. The crystalline structure was examined by X-ray diffraction (XRD) and morphology investigated by scanning electron microscopy (SEM). The crystallite size of the deposited particles could be estimated by evaluating the line width of the Bragg peak applying the Scherrer method. All the XRD patterns clearly show the five main characteristic peaks of the face-centered cubic (fcc) crystalline for both Pt and Ag crystallite. The obtained Pt crystallite sizes were below 5.5 nm, while the Ag crystallite sizes were about 32 or 34nm.
AB  - Nanostrukture plemenitih metala (Pt i Ag) na ugljeničnom materijalu, kao nosaču, su napravljene, polazeći od fruktoze i rastvora soli plemenitih metala (H2PtCl6 x 6H2O ili AgNO3) pri hidrotermalnim uslovima. Komercijalna fruktoza (C6H12O6) deluje kao izvor ugljenika i redukujući agens, a soli plemenitih metala, kao izvor metala, koji treba da se inkorporira u novonastalu strukturu ugljeničnog materijala. Kristalita struktura je ispitivana pomoću difrakcije X-zraka (XRD) a morfologija je ispitivana pomoću skanirajuće elektronske mikroskopije (SEM). Veličina kristalita deponovanih čestica se računa iz širine linije Bragg-ovog pika koristeći Scherrer-ov metod. Svi XRD uzorci jasno pokazuju pet karakterističnih pikova površinski centrirane kristalne rešetke (fcc) i za kristalite Pt i za kristalite Ag. Dobijeni kristaliti Pt imaju veličinu manju od 5.5 nm, dok su veličine kristalita Ag oko 32 i 34nm.

AB  - Bimetallic electrodes prepared by Pd nanoislands spontaneously deposited on polycrystalline platinum, Pt(poly), at submonolayer coverage were explored for methanol oxidation in alkaline media. Characterization of obtained Pd/Pt(poly) nanostructures was performed ex situ by AFM imaging, spectroscopic ellipsometry and by X-ray photoelectron spectroscopy. In situ characterization of the obtained electrodes and subsequent methanol oxidation measurements were performed by cyclic voltammetry in 0.1 M KOH. Platinum surface with 35% Pd coverage exhibited the highest catalytic activity for methanol oxidation in alkaline media, exceeding those of bare Pt and Pd. Both synergistic and electronic effects are responsible for such enhanced catalysis. The origin of the synergistic effect and possible reaction pathways for methanol oxidation were discussed taking into account the activity of obtained bimetallic electrodes for the oxidation of CO and formaldehyde, as the most probable reaction intermediates.

AB  - Oxygen reduction reaction (ORR) was investigated on polycrystalline palladium, Pd(poly), in acid and alkaline solutions using rotating-disc electrode technique. Pd(poly) was prepared in non-aqueous media which provided surface with good quality and reproducibility. According to cyclic voltammetry curves and to the analysis of polarization curves for ORR and of ones obtained separately for hydrogen peroxide reduction/oxidation reactions, ORR in both media proceeds mainly through 4e-series pathway in the potential regions where Pd surface is either oxide free or oxidized to PdOH. ORR occurs partly through 2e-reduction in the potential region where PdO is present on the surface. As revealed by cyclic voltammetry, spectroscopic ellipsometry and by atomic force microscopy, Pd(poly) surface undergoes both topography and chemical changes during ORR. Pd surface roughness as well as the degree of its oxidation increase during ORR.

AB  - Hydrogen evolution reaction (HER) was investigated on bimetallic Rh/Pd(poly) electrodes in alkaline solution. Bimetallic electrodes were obtained by a spontaneous deposition of rhodium on polycrystalline Pd. Characterization of obtained electrodes was performed ex situ by atomic force microscopy and by spectroscopic ellipsometry. The results have shown that the coverage of palladium substrate with the deposited Rh nanoislands was up to 50%, depending on the chosen deposition time. Electrochemical properties and catalytic activity of Rh/Pd(poly) nanostructures for HER were examined in 0.1 M NaOH solution by cyclic voltammetry and linear sweep voltammetry. Rh/Pd(poly) electrodes have shown an enhanced activity for HER with respect to bare Pd(poly), which was ascribed to the strong electronic interaction between palladium substrate and the deposited rhodium islands. The enhanced catalytic activity of 50% Rh/Pd(poly) for HER in alkaline solution is comparable to that of bare Pt(poly).

AB  - The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium trifluoride (YbF3) after immersion at 37 A degrees C for 7 days in distilled water or phosphate buffer saline. Specimens measuring 8 mm in diameter and 1 mm in thickness were fabricated from PC with the addition of 10, 20, and 30 wt% Bi2O3, ZrO2 or YbF3. ProRoot MTA (Dentsply, Tulsa, OK, USA) and pure PC were used as controls. For radiopacity assessments, specimens were radiographed alongside a tooth slices and an aluminum stepwedge on Extraspeed occlusal dental films (Insight Kodak, Rochester, New York). Mean optical density of each specimen was calculated and used to express radiopacity of the material as an equivalent thickness of aluminum. Compressive strength was measured by using 4-mm diameter and 6-mm high specimens and Universal testing machine. High-pressure mercury intrusion porosimeter (Carlo Erba Porosimeter 2000) was employed to measure the porosity of the specimens. The setting time was measured by using a needle of 100 g in weight. The morphology of specimens was evaluated using a scanning electron microscope (TESCAN Mira3 XMU, USA Inc.). Data were analyzed by one-way ANOVA and post hoc Tukey test (P  LT  0.05). The PC with the addition of at least 10 wt% Bi2O3 and 20 wt% ZrO2 or YbF3 demonstrated greater radiopacity value than the recommended 3 mmAl cut-off. ZrO2 and YbF3 increased the compressive strength of PC, but it was not statistically significant (P > 0.05), while Bi2O3 decreased it (P  LT  0.05). All radiopacifiers significantly increased the porosity of the experimental cements (P  LT  0.05). Bi2O3 extended the setting time of PC (P  LT  0.05), whilst ZrO2 and YbF3 did not significantly affect it (P > 0.05). ZrO2 and YbF3 may be used as a suitable alternative to replace Bi2O3 in MTA without influencing its physical properties.
