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: Mesoporous silica-based materials are being studied as bioscaffolds for bone regeneration. Zinc ion incorporation is important for bone regeneration and antimicrobial activity. This study compares the effect of pore size, geometry, and structure on the zinc loading and release of two different mesoporous silica materials. The results show that a 5 wt% zinc loading is sufficient for antibacterial effects and osteogenic differentiation of bone marrow-derived stromal cells.

Summary: The removal of phosphate from water is crucial for protecting the ecological environment due to the widespread use of phosphorus fertilizers causing water deterioration. In this study, calcium carbonate-loaded mesoporous SBA-15 nanocomposites with different Ca:Si molar ratios (CaAS-x) were synthesized as effective phosphorus adsorbents. Various characterization techniques were used to examine the structure, morphology, and composition of the nanocomposites. The results showed that increasing the Ca:Si molar ratio improved the phosphate removal capacity, with CaAS-0.55 exhibiting the highest adsorption capacity. The mesoporous CaAS-0.55 nanocomposite demonstrated fast and efficient removal of high concentrations of phosphate in contaminated wastewater.

Summary: This study investigates the sorption and desorption behavior of SO2 on PEI-SBA-15 sorbents, finding that temperature and PEI loading greatly affect sorption performance. Regenerability of spent sorbents is limited due to strong chemical interactions between SO2 and amine sites. Competitive sorption between SO2 and NO2 is observed, suggesting potential use of PEI-SBA-15 sorbents for deep removal of pollutants from cathode air in fuel cells.

Summary: Copper containing SBA-15 materials were prepared using a simple surfactant-assisted impregnation method. The surfactant in the synthesized SBA-15 played a crucial role in facilitating the distribution of copper species into the channels. Characterization results demonstrated that the surfactant-assisted impregnation method was superior to the conventional impregnation method in obtaining highly dispersed Cu-SBA-15 with isolated copper species and small clusters. These materials exhibited excellent CO oxidation activity and stability due to the finely dispersed Cu species and active sites.

Summary: Promoted Ni/Y/SBA-16 catalysts exhibited enhanced catalytic performance in CO2 methanation, with the catalyst promoted with 10 wt% Y showing the best activity. The improved performance was attributed to increased reducibility of nickel species, higher surface oxygen species, and the presence of moderate basic sites caused by yttrium promotion.

Summary: A kinetic study of ethylene oligomerization on mesoporous 2 wt% Ni-AlKIT-6 was conducted in a fixed bed flow reactor. The main products identified were n-butenes and hexenes. The proposed Cossee-Arlman coordination-insertion mechanism explained the formation of these primary products. An activation energy and global kinetic order were determined, suggesting that ethylene insertion into the metal-alkyl bond is the kinetically limiting step.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
