AB  - Nanosized Ag-doped ceria (Ce1-xAlxO2-δ)powders (0.1 ≤ x ≤ 0.04) were obtained by self-propagating room temperature reaction. The solid solubility of Ag into ceria lattice was the highest reported so far. X-ray diffraction analysis and field emission scanning microscopy results showed that the doped samples are single phase solid solutions with fluorite-type structure and all prepared powders were nanometric in size. The average size of Ce1-xAgxO2-▯ particles lies at about 4 nm. Raman spectra revealed an increase in the amount of oxygen vacancies with the increase of Ag concentration, such as is foreseen. The thermal stability of solid solution was followed by XRD. Microstructure development was studied by scanning electron microscopy. By controlling the processing variables, it was possible to obtain high density samples with homogeneous microstructure at low sintering temperature. © 2020 Elsevier Ltd

AB  - Ab initio calculations using hybrid B3LYP functional were performed in order to investigate structural, electronic and mechanical properties of aluminum nitride as function of pressure. Electronic properties of the experimentally observed aluminum nitride modifications at standard and high pressures have been investigated. Furthermore, mechanical properties for each of the predicted and experimentally observed AlN modifications have been investigated in order to get insight into the phase stability. In addition, ductility/brittleness relationship, character of the bonding, and the relationship between calculated hardness Hv, Young's modulus E, bulk modulus B, and shear modulus K have been investigated. In this way, we address new possibilities for improving the mechanical and elastic properties of AlN based ceramic materials, as well as possible band gap tuning, which might have applications in optoelectronic devices.

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  - Transition metal silicides have attracted great attention due to their potential applications in microelectronics, ceramics, and the aerospace industry. In this study, experimental and theoretical investigations of tungsten based silicides were performed. Tungsten disilicide (WSi2) was synthesized by simple thermal treatment at 1350 degrees C for 4 h in an argon atmosphere. These optimal synthesis conditions were obtained by variation of temperatures and times of heating, and the structure of the final synthesized compound was determined by XRPD analysis. In addition, new modifications for WSi2 were proposed and investigated using first-principles calculations within density-functional theory (DFT). Both LDA and PBE calculations show excellent agreement with experimental observations and previous calculations for the existing modifications, where available.

AB  - Nanosized Mg-doped ceria powders were obtained by self-propagating room temperature reaction without using surfactants or templates. X-ray diffraction analysis and field emission scanning microscopy results showed that the doped samples are solid solutions with fluorite-type structure and spherical morphology. Raman spectra revealed an increase in the amount of oxygen vacancies with the increase of Mg concentration. This increasing results in a narrowing of the bandgap of CeO2. The photocatalytic performances of the Mg-doped ceria solid solutions were evaluated by decomposing an organic dye, crystal violet under UV irradiation. The Mg-doped ceria solid solutions exhibit significantly better photocatalytic activity than the pure CeO2 and commercial TiO2. The higher first rate constant of the Mg-doped samples demonstrated that they are much more efficient than TiO2 and CeO2 under UV light. Mg2+ dopant ions and oxygen vacancies play a significant role in the enhancement of photocatalytic performances of the Mg-doped ceria.

AB  - Hexagonal boron nitride (h-BN) nanoplatelets with similar to 99 wt.% purity, 900 to 2000 nm particle width, 30 to 90 nm particle thickness, similar to 213 m(2)/g specific surface area (SSA), similar to 66% micropore SSA and similar to 0.85 nm average pore size were synthesized in a powder form using H3BO3 and CO(NH2)(2) as precursors followed by consecutive thermal treatments under inert and oxidized atmospheres. Thermal gravimetric analysis (TGA) combined with differential scanning calorimetry (DSC), under synthetic air-flow and up to similar to 1300 degrees C, were employed to evaluate both purity and oxidation resistance of the product directly upon its synthesis. The h-BN powder was collected at the stage of its highest purity which, based on TGA-DSC data, corresponded to an additional heat treatment up to similar to 700 degrees C. The active oxidation seems to occur in the temperature range between similar to 860 and similar to 1000 degrees C, followed by formation of B2O3 in the final residue. Subsequently, the purified h-BN powder was extensively characterized for its structure, morphology and porosity using X-ray diffraction, scanning electron microscopy and nitrogen gas adsorption/desorption measurements at 77 respectively. As briefly discussed, purity and SSA seem to have a crucial role in the thermal stability and oxidation resistance of BN materials in general. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - Nanoemulsion technique, based on Ouzo effect, was applied for synthesis of the pure and silver doped (2.5 and 5 mol%) calcium hydroxyapatite (HAp). After calcination at 500 degrees C fully crystallized powders were obtained. X-ray powder diffraction analysis accompanied with Rietveld refinement revealed that the synthesized powders were single-phase hydroxyapatite. Raman spectroscopy also confirmed that the synthesized powders were single-phase. The obtained HAp particles were spherical in shape and their sizes were in the nanometer range which was revealed by field emission scanning electron microscopy analysis (FESEM). The successful synthesis of the single-phase Ag doped HAp showed that nanoemulsion method is a simple technique for obtaining pure and doped hydroxyapatite nanospheres.

AB  - Simple route was used for synthesis of nanostructured titania samples doped with 3 and 6 mol% of Cr3+ Titanium(IV)-isopropoxide and water were used as starting materials and as an agents for controlling hydrolysis and condensation reactions. The phase evolution of titania (TiO2) was followed by calcination at 400, 600 and 800 degrees C. The synthesized powders were examined by field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD). Single-phase anatase was obtained at low temperature (400 degrees C) in all cases. The photocatalytic activity of TiO2 doped nanopowders was evaluated by the photocatalytic degradation of crystal violet in aqueous solution. The present study indicates that this simple synthesis method can be an effective route to produce efficient photoactive doped anatase nanopowders. (C) 2015 Elsevier Ltd and Techna Group S.r.l.

AB  - Amorphous hafnia (HfO2) powders were synthesized through a novel reduction oxidation route, in which, metal hafnium was reduced from hafnium tetrachloride (HfCl4) by sodium borohydride (NaBH4), and then oxidized in ambient atmosphere. 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. The morphologies of powders calcinated at higher temperatures were followed by Scanning electron microscopy (SEM). (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Nanoemulsion technique was applied for synthesis of carbonated strontium hydroxyapatite (CSrHAp) at room temperature. X-ray powder diffraction analysis accompanied with Rietveld refinement reviled that synthesized powder were single-phase hydroxyapatite. Fourier transform infrared (FTIR) spectroscopy showed that the CSrHAp was A-type substitution. The carbonate amount substituting the hydroxide group in the synthesized apatite was estimated, from the corresponding CO2 weight loss in the range 600-1100 degrees C. According to this empirical formula of as synthesized CHAp is S-10(PO4)(6)(OH)(0.60)(CO3)(0.70). These results were confirmed by the Rietveld refinement analysis. Using scanning electron microscopy analysis it was found that the synthesized CSrHAp particles were spherical in shape and that their sizes were in the nanometer range.

AB  - Nanocrystalline hexagonal boron nitride powders (h-BN) were synthesized from urea and boric acid followed by pirolysis and subsequent heat treatment in nitrogen atmosphere. Materials have been analyzed by means of X-ray diffraction, Photoluminescence and Field emission electron microscopy methods. Obtained results show that starting h-BN powder, synthesized at 750 degrees C, is composed of similar to 11 layer crystallites with average crystallite thickness and crystallite lateral size of 3.94 and 10.4 nm, respectively. A broad emission and intense luminescence intensity were observed due to the large atomic disorder. Higher annealing temperature increases crystallite size and turbostratic h-BN transforms to well crystallized h-BN at 1500 degrees C. (C) 2016 Elsevier Ltd and Techna Group S.r.l.

AB  - Fine tungsten carbide (WC) powder was prepared by solid state reaction between tungsten powder (W) and activated carbon cloth as a new carbon (C) source. The effect of temperature and time of heat treatment as well as the effect of C/W ratio on WC phase formation was studied. The results obtained by X-ray powder diffraction (XRPD) show that obtained powder is single WC. Microstructure and morphology was determinate by means of scanning electron microscopy (SEM). Brunauer-Emmett-Teller (BET) method was used for examining specific surface area and texture of obtained powders. It was found that WC powder was successfully synthesized in excess carbon after eight-hour heat treatment at relatively low temperature (1000 degrees C). (C) 2014 Elsevier Ltd and Techna Group S.r.l.

AB  - The fabrication of SiC-HfC ceramic composite via self-propagating high-temperature synthesis and simultaneous consolidation was investigated. Dense composite consisting of alternating layers of SiC and HfC was obtained by spark plasma sintering of stack of SiC cloths covered by electrophoretically deposited HfO2. The deposited HfO2 was converted into HfC during sintering. The obtained ceramics was characterized in terms of microstructure, cavitation resistance and oxidation resistance. It was shown that spark plasma sintering is effective way to preserve fibre-like mikrostructure of SiC. The obtained material showed good erosion resistance. The surface layer of HfC transformed to HfO2 during oxidation of samples and protected SiC from further oxidation.

AB  - A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium and strontium nitrates. The template was derived from linden wood (tilia amurensis). Repeated pressure impregnation, heat treatments and final calcination at 1000 degrees C in air resulted in the template burnout and consolidation of the oxide layers. The obtained products had structure which corresponded to the negative replication of biological templates. X-ray diffraction, scanning electron microscopy, Raman spectroscopy and porosimetry were employed to characterize the composition and structure of biomorphic ceramics. It was found that the wood impregnated with water solution of cerium and strontium nitrates was converted into oxide ceramics (Ce0.9Sr0.1O2-delta), while preserving the microstructural features of the biological preform.
