AB  - Nanocrystalline manganites Ca1-xGdxMnO3(x=0.05, 0.1, 0.15, 0.2) were synthesized by a modified glycine-nitrate procedure. The subsequent studies were focused on the structural, microstructural and magnetic changes of the starting materials induced by calcination and sintering. Thermal treatments of the green bodies were carried out by conventional sintering method. Phase evolution, lattice parameters, chemical composition and magnetic properties were monitored by Differential thermal analysis (DTA), X-ray diffraction (XRD),Induction coupled Plasma Atomic Emission (ICPES), Scanning electron Microscopy with Energy Dispersive Spectroscopy SEM/EDS and magnetic measurements on Superconducting Quantum Interference Device (Squid).DTA revealed phase transition at ≈918ºC.Chemical analysis has been done by ICPES and EDSwhich confirmed that nominal composition has been attained for all samples. XRD data were analysed by Rietveld refinement which showed that orthorhombic perovskite structure, S.G. Pnma (62), persisted with the change of Gd content, while unit cell parameters depended on the composition. Magnetic measurements show that electron doping by Gd3+ ions substantially changes CaMnO3 antiferromagnetic behavior. After introduction of Gd3+ ions, significant ferromagnetic component appears due to an emergence of double exchange interaction between Mn3+-Mn4+ ions. This resulted in appearance of a low temperature plateau in field cooled magnetization diagram as well as in hysteresis loop with the relatively high coercivity up to 2300 Oe.

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  - Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and dicyclopentadiene (DCPD) were incorporated into a fiber-reinforced epoxy with the aim of improving the flow of healing agents to the crack site. The morphological investigation of the crack site was performed using field emission scanning electron microscopy (FESEM), showing the difference between the samples depending on the used solvent. The software analysis of sample photographs has been performed by calculating the fractured/ healed surface area of the samples, revealing that approximately 20% of the volume was affected by the impact. Fourier transform infrared spectroscopy (FTIR) revealed that poly (dicyclopentadiene) (PDCPD) formed at the healed interface. However, the FTIR investigation of catalyst stability in different solvents showed structural changes in GC and partial deactivation. The mechanical tests of the samples showed that a recovery of 60% after 24 h at room temperature could be achieved through the use of a solvent and very low concentration of GC. The performed research results are a good base to develop the model for predicting the processes and morphology, with the goal to design the final mechanical and in the future, thermal, properties in advance. This opens a new direction for future research in the field of composite healing.

AB  - In this study we have combined two research methods: structure prediction of ZnTiO3 using computational SPuDS software, and the characterization of binary oxides obtained from ZnO TiO2 system. Pure nanosized ZnTiO3 (99.5%), was compacted in cylindrical shape specimens by uniaxial double sided compaction and then sintered in air atmosphere in a dilatometric device [1,2]. One compact was sintered up to 915 °C to retain metastabile ZnTiO3 and held 5 minutes on that temperature, and another one at the same conditions, but now up to 970 °C to induce phase transition and to obtain stabile Zn2TiO4 and TiO2 according to phase diagram [2]. Reheated samples obtained at different characteristic temperatures in air were analyzed by X-ray diffraction (XRD). The infrared attenuated total reflectivity measurements confirmed XRD results. In order to estimate theoretical stability of these perovskite structure, Goldschmidt tolerance factor Gt and global instability index GII were calculated. Furthermore, the Ti valence states were determined by bond valence calculations (BVC). Also, we have investigated the formation of new phases (Zn2Ti3O8, TiO2 and Zn2TiO4) originating from ZnTiO3 with temperature change, as well as the relation between the crystal structures which have been predicted and the structure of the phases we have experimentally observed.

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 °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+ −OV defect complex could be generated at elevated temperatures followed by formation of trivalent Fe ions, which intensely provide local 3d moments.
