Summary: The parameters optimization of solvothermal synthesis of lithium niobate (LiNbO3, LN) nanocrystals from Nb2O5 and LiOH was investigated. The effects of polyol media, reaction time, and Li excess on the phase composition were studied. The best yield and homogeneity of LN phase were achieved using diethylene glycol medium with a Li/Nb ratio of 1.5 and a 72 h reaction time. The LN particles exhibited a narrow size distribution and sizes below 100 nm, as characterized by scanning electron microscopy.

Summary: This study examines the impact of sintering temperature and nano boehmite additions on the phase composition, densification, and mechanical properties of porous cordierite ceramics. Sintering temperatures ranged from 1200 to 1400 degrees C. Carbon powder was used as a pore forming agent to increase ceramic porosity. The addition of nano boehmite and carbon significantly increased ceramic porosity and average pore size. The microstructure of the sintered samples showed that the crystallinity of the formed phases increased with increased nano boehmite additions.

Summary: This research focuses on the influence of atomic arrangement on the electrical and catalytic properties of oxide thin films. The atomic arrangement of LiNiO2 thin films was investigated by uniaxial compression and annealing at 600℃ on sapphire substrates. Thin films with a rock-salt structure were grown using pulsed laser deposition method at room temperature. It was observed that the as-grown thin films transformed from a rock-salt to a layered structure after uniaxial compression at 600℃, and the layer thickness of the latter structure increased with increasing uniaxial compression pressure. Uniaxial compression provides a useful tool for oxide thin film research, contributing to the development of new functional oxide materials and adjustment of the atomic ordering of cation materials.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
