Summary: The sol-gel process was used to synthesize ferrite Ni0.3Zn0.7Cr2-xFexO4 nanoparticles, which were then calcined at various temperatures. The structure and magnetic properties of the nanoparticles were characterized by XRD, SEM, VSM, and Mossbauer spectrometry. The results showed that the nanoparticles had a single-phase spinel structure and low magnetization due to the absence of ferromagnetic Ni2+ ions and weak interactions between Fe3+ ions.

Summary: Titanium carbide nanopowders and nanowhiskers were synthesized using the sol-gel process with phenolic resin and titanium alkoxide as precursors. The synthesis temperature and soaking time were found to affect the free carbon content and the formation and morphology of TiC nanopowders. Nucleation of titanium carbide occurred at approximately 1200 degrees C and ended at 1400 degrees C. The synthesized nanopowders had mesoporous structure with a specific surface area of 150 m2/g, and TiC nanowhiskers heterogeneously nucleated and grew in a soaking time of 3 h. The free carbon content in the synthesized product under 3 h soaking time was less than 1%.

Summary: This study successfully synthesized nano alpha-alumina by an inorganic sol-gel method. By varying the concentration of the precipitating agent and the order of reaction, aluminum hydroxide was obtained as the product. Aluminum chloride and aluminum nitrate were used as precursors, and the desired nano alumina phase was obtained after calcination at 1,200 degrees C. The alumina powders were analyzed using various characterization techniques, and the results showed that 89% Al(OH)(3) and 58% Al2O3 were obtained after calcination under the condition of simultaneous addition of 12 M sodium hydroxide, aluminum chloride, and aluminum nitrate.

Summary: In this study, garnet material with the composition of Li6.4Ga0.2La3Zr(2-x)YxO12(x = 0,0.1,0.3,0.5) was synthesized using the combustion sol-gel method. The phase evolution, microstructure, and ionic conductivity were analyzed. Yttrium was found to promote densification and grain growth, but excessive yttrium resulted in the formation of a secondary phase. The highest ionic conductivity was achieved in the Li6.4Ga0.2La3Zr1.7Y0.3O12 sample with a relative density of 96.6%. Lower sintering temperature and holding time were used compared to previous reports with similar densities and conductivities, thanks to the effectiveness of Ga/Y in promoting sintering and the good sinterability of the synthesized powders. This synthesis method has the potential for large-scale production due to its reduced energy and time requirements.

Summary: In this study, nanoparticles of ε-Fe2O3 in an amorphous silica matrix were prepared using the sol-gel method, showing wide size distribution and dependence on various factors. X-ray diffraction patterns and transmission electron microscopy analysis were used to characterize the samples, revealing the formation of crystalline iron oxide phases at higher temperatures and the presence of octahedral and tetrahedral iron sites in the ε-phase. The optimized conditions for preparation of ε-Fe2O3 rich sample were confirmed, achieving around 90% of the ε-Fe2O3 phase with a particle size of 15 nm and demonstrating high coercivity of approximately 1.18 T at room temperature in the nanoparticle system.

Summary: This study develops a novel fabrication method based on the sol-gel method, using boehmite as an alumina precursor and graphene oxide nanoplatelets as the reinforcing phase. Full densification of the samples was achieved through reactive spark plasma sintering under milder conditions than usual. Structural and mechanical characterizations confirm improvements in the homogeneity of the distribution of the graphene and the chemical bonds between the matrix and the reinforcing phase, although no significant changes were observed in Young's modulus, hardness, or fracture toughness.
