Summary: Tantalum oxide is utilized for water splitting, with Ta2O5 nanopowders produced using the sol-gel process. The calcination time significantly impacts the crystal structure of Ta2O5, leading to different specific capacitance and current density values of Ta2O5 electrodes under various temperature conditions.

Summary: By assembling TiO2 nanoparticles decorated with polyoxometalate (POM) and organic dye molecules, we have achieved accelerated room-temperature sensing of NO2 gas under visible light illumination. This method improves the sensitivity and response/recovery time of the gas sensors, while maintaining high selectivity and relatively low detection concentration.

Summary: Phosphors of Lu2.94Al5O12:0.06Ce3+ prepared via a sol-gel process showed significantly enhanced photoluminescence properties under different synthesizing temperatures and fluoride fluxes, resulting in green-yellow emissions due to Ce3+ transitions. Among them, the 6 wt% BaF2-added Lu2.94Al5O12:0.06Ce3+ phosphor synthesized at 1400 degrees C exhibited the highest emission intensity, 173% stronger than that of the flux-free phosphor.

Summary: The thermodynamics of the transition between two supramolecular aggregates of sodium deoxycholate in aqueous solution were characterized in this study. The morphological transition between the two structures was observed using electron microscopy. The results indicated that the transition process was influenced by factors such as temperature, pH, and surfactant concentration.

Summary: TiO2 samples with different crystal sizes and compositions were synthesized using a sol-gel method at different calcination temperatures. Increasing calcination temperature and SCW gasification/SCW treatment decreased the surface area of anatase TiO2 due to growing crystallite size. Among anatase and rutile TiO2 samples, optimal materials for hydrogen formation from formaldehyde in SCW were found. An increase in CO2 formation in the presence of anatase TiO2 was observed compared to rutile TiO2 due to active lattice oxygen species.

Summary: (Lu1-xYx)(2.94)Al5O12:0.06Ce(3+) and (Lu1-yGdy)(2.94)Al5O12:0.06Ce(3+) phosphors were prepared by the sol-gel method with a cubic garnet crystal structure. The substitutions of Y3+ and Gd3+ for Lu3+ in the Lu3Al5O12:Ce3+ phosphors affected the environment of Ce3+ and photoluminescence properties. The lattice distortion factors and maximum emission wavelengths were investigated to study the influence of Y3+ and Gd3+ concentrations on the emission wavelengths of the substituted phosphors. The Y3+ and Gd3+ substitutions induced lattice distortion and shifted the emission band towards the red spectral region. Empirical equations between lattice distortion factors and maximum emission wavelengths were proposed. The Y3+ and Gd3+ substituted phosphors showed tunable emission wavelength for potential applications in white light-emitting diodes.

Summary: This paper discusses the successful deposition of mono- and double-layer coatings of silane-Al2O3/multi-walled carbon nanotube (MWCNT) nanocomposites on magnesium alloy (AZ91) to enhance its corrosion resistance. Various characterization techniques were employed to evaluate the performance of the coatings with different MWCNT contents. Results showed that incorporating an appropriate amount of MWCNTs improved the corrosion resistance, with the double-layer coating showing better performance. This coating system has the potential to effectively protect AZ91 magnesium alloy against corrosion.

Summary: Glass-ceramic nanospheres of molar composition 0.83 SiO2 • 0.17 TiO2 are produced by the sol-gel spray-drying method, followed by controlled heat treatments up to 1200 degrees C. TiO2(B) and anatase nanocrystals are precipitated in the glassy matrix, with crystal sizes increasing over time. The nanospheres exhibit noticeable photocatalytic activity under UV-A irradiation, especially during annealing stages with higher amounts of TiO2(B) and smaller crystals.

Summary: An amorphous TiO2 nanoparticle (8-AT) was prepared via sol-gel method with pH adjustment to 8 using ammonia. The 8-AT had a particle size of 20-24 nm and specific surface area of 365.68 m2/g. It showed higher degradation efficiency for tetracycline (TC) compared to anatase TiO2 and P25, achieving 93.9% degradation within 30 minutes in dark reaction and 60 minutes under visible light irradiation. The study proposed a possible degradation mechanism based on the adsorption-photocatalytic activity of 8-AT.
