AB  - Sodium ion batteries (SIB) present one of the most perspective post lithium technology and their progress strongly depends on the development of compounds having the structure which enables fast sodium insertion/deinsertion reactions. Polyanion compounds have been widely investigated as cathode materials for SIBs where they compete effectively to the usually used layered oxides. This survey is focused on the development of specific family of isostructural polyanion phases encompassed by the common chemical formula Na4M3(PO4)2(P2O7). The comprehensive retrospective of their synthesis procedures, the kinetics and mechanism of sodiation/desodiation reactions, based on both experimental and theoretical results, is provided. First, the review summarizes the structural properties of variety of Na4M3(PO4)2(P2O7) compounds in terms of its electrical, vibrational and surface properties. Then, the synthesis methods and sodium/lithium storage performance, of each type of Na4M3(PO4)2(P2O7) compounds, are chronologically presented and discussed. Finally, the strengths and weaknesses of these mixed polyanion cathodes are outlined, with the aim to explain some discrepancies and unclarified issues encountered in the literature. Besides, this survey will make room for future development. It can be very useful for the future design of high-performance mixed polyanionic compounds as cathodes for alkaline-ion rechargeable batteries.

AB  - The oxide mixtures xCuO-(1-x) MoO3 were synthesized by gel-combustion procedure. The existence of phase mixture CuO + Cu3Mo2O9 and MoO3 + CuMoO4 in CuO-rich and MoO3 -rich composition region, respectively, were evidenced. The constant heating rate thermogravimetry in hydrogen atmosphere revealed that the reduction reactions proceed within the two clearly separated temperature regions. On the basis of mass changes, the mechanism of reduction processes was discussed. The measurements revealed considerable inhibition of CuO reduction by MoO3, and huge acceleration of MoO3 → MoO2 reduction step by copper. The particularities found in this system were commented in relation to our similar studies in NiO-MoO3 and CuO-WO3 systems. For particular composition, x = 0.5, existing preferably in form of a-CuMoO4, kinetic parameters of reduction were determined. The composition of oxide mixture influenced the particle size and morphology of resulting metallic Cu-Mo composites.

AB  - Advancements in contemporary technologies require deep
understanding of the link between the structure and properties of novel materials. Computational methods have been proven as a powerful tool in that quest,
allowing investigation of systems of various complexity and at different spatial and
temporal scales, with a desired composition and without any risk of contamination.
Moreover, constant increase of computational power allowed the application of
some of the most advanced computational methods at the scales which overcome
sub-nanometers (small molecules and clusters of atoms), usually considered as a
limit for first principles calculations. While the accuracy of such calculations reaches the experimental one, this approach also allows for the screening of a large number of systems, which is not experimentally feasible, and also the understanding of
general trends which is of great importance for both theoreticians and experimentalists. This text will cover author’s recent experiences in modelling and simulation
of nanoscale systems of different complexity, including metal oxides, metals, carbon
materials, molecular networks and complex catalytic systems.

AB  - To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in a sol-gel procedure (SG), and the other in a solid-state reaction (SS). The X-ray diffractograms (XRD) of both samples overlapped with that of pure LiFePO4, taken from the crystallographic database. Scanning electron microscopy pictures indicated the high degree of interparticle sintering, which caused a considerable agglomerate growth. The results of potentiodynamic measurements in aqueous LiNO3 solution revealed that for SS sample, three times higher initial capacity from that of SG one, (amounting to 74 mAh g−1 at 5 mV s−1). However, capacity fade on rising scan rate is much more expressed for SS sample than for SG one. We suggest that a different degree of material utilization due to the incomplete coverage of olivine particles by carbon explains this difference. The technique of separation of diffusion and capacitance currents was applied in a kinetic analysis, but it was shown to be inappropriate. We suggest the inapplicability of classic CV theory to the intercalation system accompanied by phase transition. Instead, a model of ohmic resistance determination of process kinetics was considered. LFPC-SS sample delivers three times larger capacity in LiNO3, amounting to 74 mAh g−1 at 1 mV s−1.

this paper and it was characterized by X-ray powder diffraction (XRD) and
field-emission scanning electron microscopy (FE-SEM). Electrochemical
performances of Na0.44MnO2 were studied by cycling voltammetry (CV) at
various scan rates in NaNO3 and LiNO3 aqueous solutions in order to
compare the intercalation/deintercalation kinetics of Li+ and Na+ ions. The
initial discharge capacity was found to be 27.1 and 27.44 in the aqueous
solution of NaNO3 and LiNO3, respectively, and after 30 cycles its values
increased for 12% in both electrolytes.

AB  - Due to their high photoactivity, photostability, chemical inertness, simple syntheses procedures as well as low cost, semiconductor materials such as TiO2, ZnO, V2O5, and SnO2, are recognized as materials with a great potential for photoelectrochemical and photocatalytic applications. In particular, they can be used as photoanode in the process of photoelectrolysis of water, or to initiate decomposition of different organic or biological pollutants in water under light irradiation. Which wavelength of light will be absorbed depends on the semiconductor band gap; semiconductors with a wide band gap (> 3 eV) can absorb light in the UV range only, while those with a narrow band gap (< 3 eV) can be activated by visible light. Current trend in photo(electro)catalysis is to develop efficient semiconductors which can be activated by absorbing natural sunlight. During the years, various approaches have been developed to modify optical properties of semiconductors thus to be capable to absorb sunlight, for example: the incorporation of transition metal ions or defects into the crystal structure, the particles’ surface sensitization, hydrogenation, coupling of semiconductors with different band gap energies, etc.

In particular, they can be used as photoanode in the process of photoelectrolysis of water, or to initiate decomposition of different organic or biological pollutants in water under light irradiation. Which wavelength of light will be absorbed depends on the semiconductor band gap; semiconductors with a wide band gap (> 3 eV) can absorb light in the UV range only, while those with a narrow band gap (< 3 eV) can be activated by visible light. Current trend in photo(electro)catalysis is to develop efficient semiconductors which can be activated by absorbing natural sunlight. During the years, various approaches have been developed to modify optical properties of semiconductors thus to be capable to absorb sunlight, for example: the incorporation of transition metal ions or defects into the crystal structure, the particles’ surface sensitization, hydrogenation, coupling of semiconductors with different band gap energies, etc.",

AB  - Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes that will happen during subsequent heating. Powders were characterized with XRD, SEM and particle seizer. Subsequent heating was monitored on TGA/DTA in an air atmosphere. After compaction of the milled powders, sintering was also performed in a dilatometric device. Sintered specimens were characterized micro structurally with SEM on a fresh breakage. Obtained differential TGA diagrams suggest intensive changes during prolonged milling of the oxidation kinetics on heating. Ferrite powders changed with milling as well as with second run heating were characterized to enable determination of the potentially best ratio of milling and heating to be applied to obtain the desired microstructure.

Interactions of bulk specimens with gaseous surrounding induce microstructure changes during heating. Sintered ZnTiO3 nanopowder samples were submitted to subsequent heating. Dilatation curves and thermogravimetric with simultaneous differential thermal analysis TGA/DTA curves were recorded. Reheating was performed in air and nitrogen atmospheres. Reheated samples obtained at different characteristic temperatures in air were analyzed by X-ray diffraction (XRD). Microstructures obtained by scanning electron microscopy (SEM) of reheated sintered samples are presented and compared. Reheating in a different atmosphere induced different microstructures.

Sintering of TiO2 nano and micro powders in air atmosphere was monitored in a dilatometer. Non compacted nano and micro powders were analyzed separately in air and nitrogen atmospheres during heating using thermo gravimetric (TG) and differential thermal analysis (DTA). The anatase to rutile phase transition temperature interval is influenced by the powder particle size and atmosphere change. At lower temperatures for nano TiO2 powder a second order phase transition was detected by both thermal techniques. Polycrystalline specimens obtained by sintering from nano powders were reheated in the dilatometer in nitrogen and air atmosphere, and their shrinkage is found to be different. Powder particle size influence, as well as the air and nitrogen atmosphere influence was discussed. [Projekat Ministarstva nauke Republike Srbije, br. OI172057 i br. III45014]

AB  - The nitrate-(glycine + malonic acid)-assisted gel-combustion process, followed by a heat treatment at 750 °C under reductive atmosphere, was used as a fast and effective way to synthesize vanadium doped olivine incorporated in carbon matrix, of general formula LiFe(1−x)VxPO4/C. The two-phased Rietveld refinement confirmed that vanadium incorporation into olivine structure was complete. The heating under reduction atmosphere caused the formation of iron phosphide to some extent, the concentration was determined by Rietveld analysis. The capacity and rate capability of these composites were tested by both cyclic voltammetry and galvanostatic cycling. Specifically, the average discharging capacities of the composite with x = 0.055, determined in an saturated aqueous LiNO3 solution equilibrated with air, at the rates of 1, 10 and 100 C, amounted to 91, 73 and 35 mAh g−1, respectively, with no perceivable capacity fade.

AB  - The simple and fast (malonic acid+glycine)-assisted gel-combustion process, followed by a heat treatment at 750oC under reductive atmosphere, is found to be a very effective way for the synthesis of (V-doped LiFePO4)/C composites. The Rietveld refinement confirms that vanadium incorporation into olivine structure was accompanied by the formation of iron phosphide conducting phase. The coulombic capacity and rate capability of (V-doped LiFePO4)/C composite, in both organic and aqueous electrolyte solutions, were significantly improved relative to an undoped sample, as revealed by both galvanostatic cycling and cyclic voltammetry. The average discharging capacities of ~5mol.%V-doped LiFePO4/C composite in an aqueous LiNO3 solution were 91, 73 and 35 mAh g-1 at 1, 10 and 100 C, respectively, with no perceivable capacity fade upon 100 charging/discharging cycles.

AB  - The remelting of iron and steel scrap in the electric arc furnaces generates the non-hazardous waste – electric arc furnace slag (EAFS), which can be disposed of to appropriate landfills. Currently, this slag found its application in conventional concrete production to improve its mechanical, chemical and physical properties, as an additive to asphalt base mixture and in cement production. In this study we have investigated the effect of alkaline dosage on the strength and thermal resistance of EAFS based geopolymers. The results have shown that these materials are mainly amorphous with some crystal phases remained from the undisolved EAFS such as larnite, gehlenite, wuestite, monticellite, calcite. Compressive strength of these materials is strongly influenced by the alkaline dosage. An increase of NaOH concentration in the interval of 7-10 M leads to the increase of geopolymer’s strength. The maximal compressive strength of EAFS based geopolymer was obtained using the 10 M NaOH. Further increase of alkaline dosage to the value of 13 M NaOH results in the slight decrease of the geopolymer strength. Additionally, depending on the synthesis parameters, EAFS based geopolymers exhibit improved durability in high temperature environments in comparison with conventional cement based materials. All investigated samples exhibit a shrinkage which is attributed to the change of porosity. The mass loss due to the loss of water was also observed. This research was supported by a Ministry of Science of Montenegro under the contract No 01-460.

AB  - Barium titanate stannate (BTS) functionally graded materials (FGMs) with different tin/titanium concentration gradient were prepared by the powder-stacking method and uniaxially pressing process, followed by sintering. Impedance spectroscopy (IS) was used to determine the electrical characteristics of FGMs and ingredient BTS ceramics, as well as to distinguish the grain-interior and grain boundary resistivity of the ceramics. Activation energies of FGMs and ingredients were calculated. It has been established that for BTS ceramics the activation energy deduced from grain-interior conductivity (0.73-0.75 eV) is defined by chemical composition, while activation energy for grain boundary conductivity (1.07-1.25 eV) is influenced by microstructural development (density and average grain size). Furthermore, for FGMs, activation energy for grain-interior conductivity kept the intrinsic properties (0.74-0.78 eV) and did not depend on tin/titanium concentration gradient, while activation energy (1.03-1.29 eV) for grain boundary was determined by the microstructural gradient. No point dissipation was observed by IS, accordingly, no insulator interfaces (cracks and/or delamination) between graded layers were detected. © 2009 Elsevier Ltd. All rights reserved.

AB  - In this study, a correlation between densification, microstructure, and electrical properties of BaTiO3 (BT) ceramics prepared from ultrasonically de-agglomerated BT powders has been analyzed. BT powders with the same crystal structure (tetragonal) and stoichiometry, but with different average particle size, were used to prepare sintered ceramics. Densification and electrical properties of the sintered BT ceramics were correlated to the average particle size of the powders. It was found that a decrease in average particle size improved the densification process as well as the ceramics' microstructure. The impedance measurements were done up to 320°C in order to separate grain (bulk) and grain boundary contributions. Bulk resistance was more or less the same, independent on the average particle size of the powder. On the contrary, grain boundary resistance increased with decreasing average particle size of the powder.
