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 CO 2 molecules, while the micropores are the most suitable for trapping of CO 2 . The sorption process analysis (including adsorption/desorption isotherms behavior) shows indication that the rate-limiting step of CO 2 adsorption onto activated carbon is probably governed by diffusion-controlled process, especially at temperatures below 850°C.

AB  - A Density Functional Theory (DFT) study has been performed in order to investigate behaviour of barium sulfide (BaS) at high pressures, and relationship between computed properties, in great detail. Novel predicted and previously synthesized BaS modifications have been calculated using Local Density Approximations (LDA) and Generalized Gradient Approximation (GGA) functionals. In particular, a detailed investigation of structural changes and its corresponding volume effect up to 100 GPa, with gradual pressure increase, has been performed from the first principles. Band gap engineering of the experimentally observed BaS phases at high pressures has been simulated and structure-property relationship is investigated. For each of the predicted and experimentally observed BaS structures, elastic constants and mechanical properties under compression have been investigated (e.g. ductility/brittleness, hardness, anisotropy). This study offers a new perspective of barium sulphide as a high pressure material with application in ceramics, optical and electrical technologies.

AB  - Bismuth ferrite (BiFeO3) was synthesized by hydrothermal method. The crystal and magnetic structures of BiFeO3 have been studied by means of X-ray diffraction and neutron powder diffraction at ambient temperature. Microstructure was analysed by scanning electron microscopy. Quantitative phase analysis by the Rietveld method was conducted and crystallite sizes of 27 nm were determined from the XRD line broadening. The magnetic structure of BiFeO3 is described by the G-type antiferromagnetic order with magnetic peak located at 4.6 Å and a noticeable magnetic contribution to a reflection located at 2.4 Å in the diffraction pattern. The values of the ordered magnetic moment of Fe ions μFe=3.8(1) μB, obtained at ambient conditions, are consistent with those determined earlier. The magnetic moments in the crystal plane z = const are arranged in parallel, changing the direction from [100] to [ 110 ] when moving from one to the other z = const plane. © 2018 Authors.

AB  - One of the recent trends in materials science and technology is the research of the behavior of the materials under the extreme conditions both on the theoretical and experimental basis. There are limitations of the experimental methods, however, theoretical approach can be used as a supplement to the experimental results. As a consequence, in the last two decades a vast number of structure prediction calculations have been performed on chemical systems, focusing on the high-pressure and high temperature phases. In this work, we would like to present several computational studies and their connection to the actual synthesis routes: lead sulfide (PbS), barium sulfide (BaS), and aluminum nitride (AlN). The investigated compounds were calculated on ab initio level using the most advanced tools in quantum chemistry and computational material science including Hartree-Fock Theory, Density Functional Theory (DFT) and Hybrid (B3LYP) Approximation. Their structural, mechanical, elastic and vibrational properties have been investigated and in addition, we show structure candidates as the function of size, pressure and temperature and not previously observed in any of the investigated materials thus creating new possibilities for synthesis of advanced materials with improved physical, chemical, and/or mechanical properties. © 2018 The Authors.

AB  - Bismuth ferrite (BiFeO3) has recently drawn attention due to its outstanding multifunctional properties, as well as for being a lead-free ceramic material. In the current study, BiFeO3 nanoparticles were synthesized by strictly controlled hydrothermal process. High geometric molded particles of a small size and with high degree of purity (99.74 %) were obtained. We used nitrates of bismuth and iron as well as 8M potassium hydroxide as a basis for synthesis. The results of the X-ray diffraction study of the obtained polycrystalline material show single-phase bismuth ferrite that crystallizes with a rhombohedral lattice. Using the Rietveld method it has been determined that the particles of the synthesized powder are in a nanometric range with a particle size of about 30 nm. It was found that all reflec-tions of the obtained bismuth ferrite belong to the rhombohedral α-BiFeO3 phase which crystallizes in the space group R3c (No. 161). In addition, electronic and magnetic properties of BiFeO3 were investigated using combination of experimental and theoretical methods. HRTEM analysis confirmed existence of twin stacking faults, which are responsible for enhanced magnetic properties. EPR measurements suggested existence of electrons trapped by vacancies or defects. It has been pro-posed that Fe3+−OV defect complex could be created at elevated temperatures fol-lowed by formation of trivalent Fe ions, which intensely provide local 3d moments. The magnetic behavior of the synthesized material was studied by means of SQUID device and using a vibrating sample magnetometer (VSM). The temperature dependence of the magnetization shows the antiferomagnetic-paramagnetic phase transition at the temperature of TN = 220K, while below this temperature weak ferro-magnetic behavior has been detected. Theoretical studies were performed using a full potential linearized augmented plane-waves plus local orbital (FP(L)APW+lo) method, based on the density functional theory (DFT). In addition, a structure prediction has been performed and 11 additional BiFeO3 modifications have been pro-posed. In the next stage, an ab initio optimization of predicted structures has been performed and the structure of the γ-phase has been elucidated.

AB  - Palladium ion-exchanged zeolite X (PdX) was prepared by zeolite impregnation with palladium acetylacetonate, followed by thermal degradation of the salt. PdX was characterised using SEM-EDS, ICP-OES and XRD. Analysis revealed presence of 7.78 wt.% of Pd in the form of PdO. Subsequently, PdX was tested for hydrogen evolution reaction (HER) in alkaline medium using linear scan voltammetry, chronoamperometry and electrochemical impedance spectroscopy measurements. The influence of addition of carbon black on the materials catalytic performance was also investigated. The HER kinetic parameters, including Tafel slope, exchange current density and activation energy, were determined. In order to provide atomic-level insights, experimental results were complemented by density functional theory calculations. It is suggested that favourable hydrogen adsorption energetics on PdO is responsible for efficient HER catalysis by this novel electrocatalyst. (c) 2017 Elsevier Ltd. All rights reserved.

AB  - Bismuth ferrite (BiFeO3) is one of the most studied multiferroic system with a large number of published articles. This is mainly because BiFeO3 material possesses both ferromagnetic and ferroelectric properties observed at room temperature, which opens great possibility for industrial and technological applications. Well crystallized single-crystal BiFeO3 nanopowder has been successfully synthesized with the hydrothermal method. The phase composition of the synthesized samples was determined by the x-ray diffraction (XRD) analysis, and the results showed that synthesized material crystallizes in the space group R3c as alpha-BiFeO3 phase, which was confirmed by the previous experiments. In addition, a structure prediction has been performed and 11 additional BiFeO3 modifications have been proposed. In the next phase, an ab initio optimization of predicted structures has been performed and the structure of the gamma-form has been elucidated. Furthermore, electronic and magnetic properties of BiFeO3 were investigated using combination of experimental and theoretical methods. Spectroscopic Ellipsometry has been used to study electronic properties of BiFeO3, while magnetic behavior of synthesized material was investigated by SQUID. Finally, theoretical studies were performed using a full potential linearized augmented plane-waves plus local orbital (FP(L)APW+lo) method, based on density functional theory (DFT).

AB  - In this paper, bismuth ferrite (BFO) particles synthesized by controlled hydrothermal process, where the particles of small sizes and with high purity were obtained. Structural analysis showed that non-annealed powder can be perfectly fitted to rhombohedral space group R3c and contains a very small amount of secondary phase, whereas the final product (annealed at 800 degrees C) represents single-phase perovskite powder with high crystallinity. HRTEM analysis confirmed existence of twin stacking faults, which are responsible for enhanced magnetic properties. EPR measurements suggested existence of electrons trapped by vacancies or defects. It has been proposed that existence of Fe3+ - O-V defect complex could be generated at elevated temperatures followed by formation of trivalent Fe ions, which intensely provide local 3d moments.

AB  - Electrodes based on composites of zeolites with carbonized polyaniline prepared in the presence of 5-sulfosalicylic acid are evaluated for both qualitative and quantitative determination of phenols in aqueous solutions. Zeolites used included NaX and NaY, as well as their transition metal (Mn and Cu) cation-exchanged forms, and they were all characterized usingXRPD, FTIR and SEM. Cyclic voltammetry was used to study composites electrochemical response in the presence of p-nitrophenol, phenol and 5-aminophenol in acidic, neutral and al- kaline media. Linear dependence of current on p-nitrophenol concentration in acidic media was obtained in 0.11 mM concentration range. The comparative evaluation of the electrochemical response of NaX/carbonized polyaniline composite and its individual components revealed significantly lower limit of detection obtained using composite electrode (1.27 mu M) compared to that obtained using pure zeolite (135 mu M) or pure carbonized polyaniline (94.5 mu M) electrode. Composite electrode gave response to p-nitrophenol presence in neutral media as well, but it quickly disappeared with continuous scanning, while no clear response could be seen in highly alkaline media. Thus, this work demonstrates benefits of using novel composite based on zeolites and carbonized polyaniline for sensing of phenols in acidic aqueous solutions. (C) 2016 Elsevier B.V.

Upon calcinations, the powder crystallized to nanometric size HfO2 powder with monoclinic structure. Powder properties such as lattice parameters, crystallite and particle size were studied. X-ray diffraction analysis (XRD) was used to characterize structure and phase evolution in synthesized samples. Calculation of the average crystallite size (D) was performed on the basis of the full width at half maximum intensity (FWHM) of the XRD peaks. Williamson-Hall plots were used to separate the effect of the size and strain in the nanocrystals.

AB  - Mesoporous monetite (CaHPO4), obtained by mechanochemical treatment of previously synthesized brushite (CaHPO4 center dot 2H(2)O), was used as efficient adsorbent for the organic pesticide malathion. The structure of brushite was confirmed by Raman spectroscopy. The phase transformation process was investigated by X-ray powder diffraction (XRD) and Fourier transformation infra-red spectroscopy (FTIR). The microstructure and morphology were determined by scanning electron microscopy (SEM) and the nitrogen adsorption-desorption method. It was found that five minutes of milling induces brushite-monetite phase transformation. Adsorption of malathion from aqueous solutions showed that this pesticide can be successfully adsorbed on surface of this material.

AB  - The kinetics of hydrogen absorption in Zr alloys containing Nb and Ta admixtures (10 wt% Nb, 12 wt%Ta and 10 wt%Nb and 12 wt%Ta) is addressed. Hydrogen absorption is measured in the temperature range 400-700 degrees C at hydrogen pressure 1 bar using the volumetric method, and a kinetic analysis is performed to determine the mechanisms and rates of hydrogen absorption. To get further insight into hydrogen diffusivity in zirconium hydride, H-1 NMR spectroscopy is used to provide the activation energies for proton jumping in the studied samples. The tantalum is found to dominantly influence the surface reactivity, while niobium influences large decrease of the activation energy for hydrogen diffusion in the bulk of zirconium hydride. This behavior is linked to the information on the structure of the alloys obtained by XRD. Copyright.(C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

AB  - Lead distribution and immobilization in cultivated soils in Rudovci, Serbia was investigated. Sampling was carried out by the method recommended by ICP-Forests Manual, 2006, Part III Sampling and analysis of Soil. The sampling geometry was systematically designed with a random component. The maximum sampling depth was 100 cm and lead distribution was monitored during 425 days. First sample was taken after 50 days and every single next sample was taken after 50 days except for the last sample which was taken after 25 days. Before the profile contamination, physical and chemical soil analysis has been done. The cation exchange capacity of the soil was done because media affect mobility cations (anions) in soil. The effect of immobilizations of Pb is highest in the second horizons where the depth of investigating soil is 25-50 cm.

AB  - Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed homogeneously on a hot plate until precursor gel was formed. Pyrolysis of this gel resulted in monoclinic hafnia which after subsequent heat treatment transformed into hafnium carbide. The obtained materials were analyzed by means of X-ray diffraction and scanning electron microscopy. The results showed that the obtained carbide powders were composed of nearly equiaxed particles with narrow size distribution. Characterization by nitrogen adsorption showed that the obtained powders were micro- and mesoporous materials with high specific surface area. (C) 2012 Elsevier Ltd and Techna Group S.r.l.

AB  - Amorphous Pr6O11 powder was obtained by applying self-propagating room temperature method (SPRT). After calcination, the amorphous powder converted to nanometric Pr6O11 powder with cubic fluorite-type structure. Powder properties such as crystallite size, lattice strain and lattice parameter were studied by X-ray diffraction (XRD) at room temperature. The crystallite size was estimated by means of the full width at half maxima (FWHM) of XRD peaks. Williamson-Hall plots were used to determine the lattice strain whereas the Ritveld analysis was employed for crystal structure refinement. It was found that the powder properties are affected by both calcination temperature and duration of thermal treatment. The crystallite size varied from 5 to similar to 250 nm, whereas the lattice parameter varied from 5.461 to 5.494 angstrom. The powder obtained after four-hour long calcination was almost free of internal strain. (C) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Nanocrystaline powders of solid solution Ce1-xBixO2-delta with the composition of x = 0.1 - 0.5 were synthesized at room temperature using Self Propagating Room Temperature procedure (SPRT). Obtained results show that all synthesized powders were single-phase solid solution at room temperature (XRPD and Raman spectroscopy). Thermal stability of these solid solutions with different concentration of Bi was investigated at various temperatures in the range of 600 - 1200 degrees C. It was revealed that all samples with higher Bi ion concentration are unstable during thermal treatment resulting in formation of alpha-Bi2O3 as second phase. Also the detail characterization is done of all samples (crystallite size, strain-stress, powder morphology, BET).
