Summary: Different synthesis approaches and conditions for misfit layer compounds (MLCs) in the ternary systems V-Se-Bi, V-Se-Pb, and V-Se-Sn were compared. The best results were achieved with NH4Cl as a crystallisation aid, moderate annealing temperatures, and longer annealing durations. The study discussed the compositions, morphology, and structure, and found that either plate-like or tubelike MLC crystals could be obtained depending on the stacking sequence of the compounds. The structural properties of MLC (PbSe)1+delta VSe2 were comparable to the corresponding ferecrystals in the literature.

Summary: In this study, a combination of imaging techniques was used to analyze lithium iron phosphate (LixFePO(4)). The results revealed the local structural and chemical variations in LixFePO(4) particles at different stages of delithiation. This study provides important insights into the LixFePO(4) system and the differences between local and global measurements in terms of lattice parameter-composition behavior. It also demonstrates a powerful approach for bridging the gap between local and statistical characterization.

Summary: Undoped and Mn-doped ZnS nanocrystals were synthesized and characterized. The substitution of Mn ions for Zn ions in ZnS nanocrystals led to changes in lattice parameters and interatomic distances. Photoluminescence spectroscopy showed a shift in emission peak due to Mn doping in ZnS nanocrystals.

Summary: A series of single-phase nickel-substituted magnesium spinel ferrites were synthesized using the hydrothermal technique, and their morphology, structure, magnetism, and electrochemical properties were investigated. Experimental characterization techniques confirmed the presence of a single-phase spinel structure, with a decrease in lattice parameter and clustering of nanoparticles as nickel concentration increased. Raman and FTIR spectra indicated changes in wave numbers and the shortening of Fe-O bonds. Additionally, the ferrites exhibited increased saturation magnetization, decreased coercivity, decreased specific capacitance, and increased loop size. These ferrites are promising for energy storage applications.

Summary: Phase transformations in a metastable beta Zr-12Nb alloy were investigated using high-energy X-ray diffraction (HEXRD) and complementary in-situ methods. Two bcc phases, l3Zr and l3Nb, were observed in the temperature range studied. The formation of l3Nb phase starts at about 300 degrees C, gradually replacing the original l3Zr phase. Ex-situ observations revealed a cuboidal shape of the u particles and the dissolution of u particles followed by the growth of the a phase at 560 degrees C.
