AB  - Ca1-xGdxMnO3 (x = 0.05–0.20) nanostructured perovskites were successfully synthesized by modified glycine nitrate procedure (MGNP). Temperature intervals of sintering and phase transition during heating were revealed during dilatometric measurements. In order to determine the band gap values of the tested samples, ellipsometric measurements were performed in the UV-VIS spectral range. Decrease of band gap values with increase of Gd dopant content was attributed to n-type doping and upward shifting of the Fermi level in the conduction band. The investigation of the crystal structure and phase content of nanocrystalline Ca1- xGdxMnO3 powders was continued using micro-Raman spectroscopy. The electrical conductivity of Gd3+ doped sintered samples CaMnO3 as a function of temperature was measured by electrochemical impedance spectroscopy (EIS), in the temperature range of 400–700 °C. The corresponding activation energies of conductivity, measured in the investigated temperature range, were also discussed. The obtained research results showed that the highest hardness values of 7.58 GPa respectively, were achieved and that these nanostructured materials can be used as a high-density ceramic material for various industrial applications.

AB  - Experimental and theoretical methods have been used to investigate the octahedral tilting and related effects of Ca1-xGdxMnO3(x = 0.05; 0.1; 0.15; 0.2) compound. Both methods have shown that orthorhombic-perovskite structure (space group Pnma) is the most stable form and according to Glazer's classification belongs to a-b+a- tilt system. Bond valence calculations (BVC) have shown ten additional perovskite-related modifications of the equilibrium Ca1- xGdxMnO3 structure, and their stability has been investigated as function of Gd doping. We have further studied the influence of gadolinium amount on Mn-О bond angles and distances, tilting of MnO6octahedra around all three axes and deformation due to the presence of Jahn- Teller distortion around Mn3+ cation, and calculated the amount of Mn3+ in the system. BVC approach is a simple, fast and efficient way of calculating the amount of Mn4+ and Mn3+ in the doped perovskite compound, which, to the best of our knowledge, has not been done before. The infrared reflection spectra of Ca1-xGdxMnO3 samples confirmed XRD results that Ca1-xGdxMnO3 nanopowders are of Pnma-1 structure and that the tilting of octahedra are increased with Gd doping. The EPR (electron paramagnetic resonance) spectra are in accordance with the assumption that EPR line width is Mn-O-Mn angle dependent. The studied samples showed that small octahedra tilting in these samples brought only a small change of the EPR line width.

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  - Geopolymers (GP) were successfully synthesized from metabentonite (MB), metadiatomite (MD) and metakaolinite (MK). Characterization of their phase structure and microstructure was performed by XRD, FTIR, SEM/EDX methods. A SEM micrograph of GPMD shows a homogeneous surface with some longitudinal cavities in the gel, and it is significantly different from the micrographs of the other two geopolymer samples, GPMB and GPMK. A considerable amount of unreacted particles, as well as the presence of pores in the geopolymer matrix of GPMK and GPMD, indicate an incomplete reaction in the system. Aluminosilicate inorganic polymers, geopolymers, are quasi solid electrolytes which possess a high electrical conductivity at room temperature in relation to materials of similar chemical composition. The highest conductivity was found for the sample obtained from GPMK, amounting to 2.14 × 10–2 Ω–1cm–1at 700 ºC. The corresponding activation energies of conductivity for this sample amounted to 0.33 eV in the temperature range of 500–700 ºC. The geopolymer synthesized from metakaolin has good ionic conductivity values, which recommends it for use as an alternative material for an SOFC (Solid Oxide Fuel Cell).

AB  - The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous solutions. The effect of different ageing times on sorption behavior of 1, 2, 10 and 19 h milled clays, as well as the clay composite with 20 wt% of amorphous TiO2(TiO2,a), was investigated. Ageing of the milled clays has stronger influence on the removal of Zn(II) and Cd(II) than on the removal of Pb(II) and Cu(II) ions. Ageing is particularly pronounced for the samples milled for 1, 2 and 10 h (which lost enhanced sorption properties after 3 months of ageing), and less pronounced for the samples milled longer period of time, 19 h (which retained sorption properties until 6 months). After these periods of time sorption capacities became nearly the same as the sorption capacities of the raw (unmilled) clay. The different responses on the ageing process of milled clays and composite are a consequence of microstructural changes such as recrystallization of montmorillonite phase and decrease in particle sizes. Slower ageing of composite compare to the milled clays can be related to the stabilization effect of TiO2particles which are dispersed in the clay matrix thus preventing recrystallization of the sample particles. Only a slight tendency towards the formation of agglomerations was noticed after 12 months of ageing. © 2014 Elsevier Ltd and Techna Group S.r.l.

The different responses on the ageing process of milled clays and composite are a consequence of microstructural changes such as recrystallization of montmorillonite phase and decrease in particle sizes. Slower ageing of composite compare to the milled clays can be related to the stabilization effect of TiO2particles which are dispersed in the clay matrix thus preventing recrystallization of the sample particles. Only a slight tendency towards the formation of agglomerations was noticed after 12 months of ageing. © 2014 Elsevier Ltd and Techna Group S.r.l.",
