Summary: In this study, amorphous silica nanoparticles with excellent corrosion resistance were synthesized using a novel method. By using rice husk as a precursor and CTAB as a surfactant, and applying microwave radiation, spherical nanoparticles with a diameter of 80-100 nm were obtained. The study also revealed that the silica coating provides better protection against corrosion for mild steel plates and can form a thin layer with Fe2+ in seawater conditions.

Summary: This study presents the preparation of self-doped V4+-V2O5 ion storage nanofilm on ITO-coating glass substrate using a novel hydrothermal-assisted sol-gel composite method. It is found that introducing oxygen vacancies during the hydrothermal process significantly improves the storage capacity and Li+ diffusion in the V2O5 film, while annealing treatment at 300°C results in the highest ion storage performance. The excellent cycling stability and performance of the 300°C-V2O5 film make it promising for applications in electrochromic devices.

Summary: This paper presents indirect methods to define the change in the rates of hydrolysis and condensation reactions of a silica oxide network. Different solvents used in the reaction environment were found to have a significant impact on the reaction rates and functional properties of the obtained silica coatings. The morphology and structure changes were investigated using various characterization techniques. The results showed that the coatings synthesized in a methanol environment had a higher polarization resistance, while the ethanol-based coatings had the greatest thickness. The acetone-based coatings exhibited higher detachment force. Propanol and butanol contributed to defects and decreased protection properties, particularly in coatings based on propanol. No statistically significant influence of solvents was observed on the thickness of coatings prepared with butanol or acetone.

Summary: The study explored the impact of aging time on the protective properties of submicron sol-gel coatings. The coatings, made of zirconia and silica modified with fluoroalkyl substituents, were applied to P265GH steel and aged for 3 years. The materials were analyzed using SEM, Raman spectrometry, and NMR to determine their physicochemical properties. The coatings' roughness and wettability were measured, while their protective properties were evaluated through electrochemical and immersion tests. The ZrO2-based coating exhibited better stability over time, while the SiO2 + F coating showed deterioration in its protective nature after 3 years. Moreover, the ZrO2 coating offered smoother coverage on the surface, while the SiO2 + F coating replicated the surface topography and formed a thin continuous film on the ridged surface.

Summary: This study examined the fluorescence emission and structural properties of a hybrid composite consisting of a silica matrix with embedded xanthyletin. Xanthyletin was easily obtained from Brosimum rubescens wood using ethyl alcohol. The fluorescence emission and structural properties of the composite were analyzed as the temperature increased, demonstrating that the interaction between the organic and inorganic components significantly enhanced the fluorescence emission. The fluorescence intensity was found to be closely related to the arrangement of the Si-O network, indicating a structural rearrangement induced by the embedded xanthyletin.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
