AB  - Pure, crystalline, similar to 10 nm lithium ferrite phase (Li0.5Fe2.5O4), was Successfully synthesized at very low temperature using a modified combustion method. The crystal structure and microstructure evolution of this system upon annealing were monitored by a careful investigation of X-ray diffractograms collected on a synchrotron source. Comparative analysis of the results obtained from the full profile Rietveld method (in reciprocal space) and the pair distribution function method (in direct space) was carried Out. Nanocrystalline samples exhibit similar crystal structure, on average, with a partial ordering of Li+ and Fe3+ ions between octahedral 4b and 12d sites on the spinel crystal lattice (space group P4(3)32). After annealing at 973 K, cation distribution changes to a completely ordered, resembling that which is seen in the bulk lithium ferrite. The PDF analysis reveals abnormally high values of oxygen atomic displacement parameters in tetrahedral 8c sites (OI) indicating a significant disordering of the OI network and suggests migration of lithium ions from 4b sites to the outer layers of nanoparticles. Analysis of room temperature Mossbauer spectra has shown that the hyperfine field for Fe3+ ions in tetrahedral 8c sites is the most sensitive on increasing the particle size and improving the crystallinity. From the differential thermal analysis, it was found that a lower driving force is required to induce an order-disorder phase transition in nanocrysalline samples, compared to the bulk-like sample, presumably due to the higher crystal disordering in these samples.

AB  - Flower-like agglomerates with sizes of 200-400 nm of pure and Fe3+-doped TiO2 with rutile crystalline structure were synthesized by the coprecipitation method. The morphology of the agglomerates was determined by electron microscopy (TEM and HRTEM). TiO2 agglomerates consist of nanorods with clearly visible crystalline faces, parallel to the axis of elongation whose direction was along the [101] direction of pure TiO2 and the [111] direction of doped TiO2. Furthermore, nanorods consist of chains of spherical particles, most likely interconnected through the so-called oriented attachment or grain-rotation-induced grain coalescence (GRIGC) process. UV/Vis reflection measurements revealed that the absorption of pure TiO2 was significantly shifted from UV toward the visible spectral region upon the incorporation of Fe3+ into the TiO2 host.

AB  - Nanoparticle La0.7Ca0.3MnO3 was synthesized for the first time by the glycine-nitrate method without additional heat treatment. The average crystallite size of similar to 10 nm obtained by both transmission electron microscopy and X-ray diffraction was among the smallest achieved by the combustion method. Magnetic measurements showed para-to-ferromagnetic transition temperature T-C = 120 K, saturation magnetization M-S = 46 emu g(-1) and transition of the spin-glass type at T-f = 95 K.
