Summary: The removal of zinc ions from water was studied using two types of ordered mesoporous silica (SBA-15 and SBA-16). Both materials were modified with APTES and EDTA through post grafting methods. The modified adsorbents were characterized by various analytical techniques, and the structural integrity was maintained. Optimal adsorption conditions and maximum adsorption capacity were determined through experimental tests, and the regenerated adsorbent showed no significant decline in adsorption efficiency.

Summary: In this study, non-supported pure and mixed cobalt and iron oxide catalysts were synthesized using a simple, environmentally friendly preparation method in which water was the sole solvent. The results showed that the mixed oxide catalysts exhibit higher catalytic activity than the pure oxides, and the Fe: Co atomic ratio is the key factor in the catalytic activity of these mixed oxides. Among the catalysts tested, the 50Fe + 50Co catalyst showed the highest catalytic activity towards methane conversion, reaching about 52.6%.

Summary: This study investigates the catalytic activity of CeO2-supported Co, Fe, and Ni catalysts in the catalytic decomposition of methane (CDM) for carbon nanotube (CNT) synthesis, with a focus on the effects of CeO2 on the activity of the active metals. The results show that Ni/CeO2 exhibits good catalytic performance at a relatively low temperature of 600 degrees C, and the catalysts were characterized using various analysis methods. Additionally, the morphology and properties of the carbon material grown on the catalysts were examined.

Summary: This work investigates the oxidation of methane, propane and ethylene in the presence of carbon monoxide (CO) and water vapors over Pt and Pd mono and bimetallic catalysts supported on SBA-15. The study finds that Pd exhibits higher activity towards alkanes (methane and propane) at low temperatures, while Pt is more active for ethylene. Optimal alloying compositions have the potential to minimize the decrease in conversion activity in the presence of CO and water vapors.

Summary: Naproxen was impregnated into mesoporous SiO2 SBA-15 using the Supercritical Solution Impregnation (SSI) technique. The percentage of naproxen impregnated decreased with increasing CO2 density and with the addition of ethanol, ethyl acetate or menthol. The impregnated naproxen on SiO2 became amorphous and showed interaction with SiO2 support. Release tests showed a sustained release system with a slower rate compared to pure naproxen due to the interaction and diffusion of the drug.
