Summary: TiO2 nanoarrays grown heterogeneously on substrate surfaces prefer solvents with moderate dielectric constants, which can be partially dissolved in aqueous solution and modulate reaction rates during solvothermal synthesis. Organic solvents with low dielectric constants may lead to a complete separation between precursors and aqueous solution, slowing down the overall reaction and causing insufficient growth of nanoarrays. The optimal morphology for TiO2 nanoarrays, with high specific surface areas and including cordierite substrate, is achieved through a combination of 2-butanone and titanium (IV) butoxide as solvent and precursor, respectively.

Summary: Hollow SiOC ceramics were prepared using a microwave-assisted solvothermal method with only mesopores formed in NaOH solution. Increasing the microwave temperature and NaOH concentration increased the oxygen-enriched units, reduced the Si-C bonds in the precursors, and enhanced the etching effect in the interior SiOC ceramics. The specific surface area of SiOC ceramics increased with higher solvothermal temperature but decreased with increasing NaOH concentration. The synthesis temperature had a larger impact on the formation of hollow SiOC ceramics compared to NaOH concentration.

Summary: Understanding the relationship between cellulose fiber morphology and the rheological behavior of its dispersions is important for optimizing their applications. Sugarcane bagasse-sourced cellulose dispersions with different numbers of high-pressure homogenization cycles were produced. Microfluidization produced cellulose nanofibers with similar surface charge densities and crystallinities. The rheological properties of the dispersions could be tuned by adjusting the length of the nanofibers, allowing for targeted applications.

Summary: Microporous and mesoporous nanocomposites based on silica and titanate were synthesized by unrolling sodic titanate nanotubes and introducing surfactant species and silica species between the unrolled titanate nanotubes. The resulting nanoarchitectures exhibit higher specific surface areas and improved adsorption capacities compared to the pristine titanate nanotubes. Kinetic and isotherm analyses indicate that the adsorption process follows pseudo-second-order kinetics and occurs through multilayer adsorption onto the nanocomposites, rather than onto uniform sites.

Summary: This study focuses on the synthesis of LTO thin films via the polymeric precursor method and their deposition onto STO substrates using spin coating. The results demonstrate the coexistence of ferromagnetic and ferroelectric responses in the LTO/STO heterojunctions at room temperature. Magnetoelectric coupling is observed under a DC bias magnetic field, and the dielectric constant is affected by the coupling between magnetic and electric dipoles as well as oxygen octahedra distortion. The film-substrate mismatch significantly influences the system's dielectric properties. Overall, this study provides insights into inducing ferromagnetic/ferroelectric phases and understanding oxygen vacancy dynamics for various electronic devices.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
