Summary: This study comprehensively investigates the factors affecting the formation of MCM-41 type mesoporous silica nanoparticles (MSN). The hydrolysis and condensation rates are found to play a central role in nanoparticle formation, and disregarded parameters such as stirring strength and surfactant addition rate are shown to modulate nucleation and growth. Furthermore, the aging and evolution of MSN are studied through the analysis of silica framework consolidation over time, providing insights into obtaining reproducible, homogeneous, and tailored-made MCM-41 type MSN.

Summary: This study reports the synthesis of mesoporous MCM-41 nanoparticles using microwave radiation. Silica nanoparticles with large surface area and suitable chemical composition were obtained at low power and short time. The particle size was close to 100 nm with a spherical morphology. The microwave radiation power and heating time affected particle size and aggregation. The MCM-41 synthesized under low microwave radiation power had a high surface area and expanded pore diameters compared to hydrothermal synthesis. The sample labeled as MCM400W10 showed a significant number of free silanol groups on the surface.

Summary: This work demonstrates the implementation of thioglycolic acid (TGA) functionalized water-soluble NH2-molybdenum disulfide (MoS2) nanosheets as sensitive layers for toxic heavy metal ion sensing in drinking water. The sensor device was tested for several ions commonly found in drinking water, and it showed that Cd had a higher response compared to Hg. The possible reason for this competitive dominance of Hg (II) adsorption may be the affinity of thiol groups present in the TGA molecules for Hg (II) over Cd (II) ions.

Summary: The study focuses on the role of 12-tungstophosphoric acid (TPA) functionalized nMCM-48 as a drug delivery carrier for weakly soluble polyphenols, curcumin and quercetin. The TPA functionalized nMCM-48 exhibits high pore volume, pore diameter, and high surface area, which are essential for drug loading and release. Both curcumin and quercetin are successfully encapsulated in TPA-functionalized nMCM-48, resulting in nanocomposites with enhanced antimicrobial efficiency. The drug release studies show a release rate of 69% for C-TPA/nMCM-48 and 67% for Q-TPA/nMCM-48.

Summary: The search for sustainable plastics is driven by the environmental pollution issues associated with petrochemical-derived plastics. Bioplastics, such as poly(lactic acid) (PLA), are increasingly being used in packaging due to limited fuel resources. However, poor ductility and gas barrier characteristics limit the use of PLA as food packaging material. This study aims to overcome these limitations by fabricating PLA/polyethylenimine-modified mesoporous silica (PEI-MS) composites. The influence of PEI content in MS and wt % loadings of optimized PEI content in MS on the properties of PLA is investigated in detail. The results show that PEI-MS modification improves the thermal stability and mechanical properties of PLA.

Summary: This study aimed to investigate the effect of pomegranate juice (PJ) on cyclosporine-induced nephrotoxicity in rats. The results showed that the administration of cyclosporine caused significant alterations in plasma creatinine, blood urea nitrogen, creatinine clearance, kidney injury molecule-1, and neutrophil gelatinase-associated lipocalin levels. However, supplementation with PJ attenuated these alterations and prevented changes in histopathology, lipid peroxidation, and antioxidant enzymes induced by cyclosporine. Therefore, PJ has a protective effect against cyclosporine-induced nephrotoxicity through its antioxidant properties.

Summary: Water pollution caused by urbanization and industrialization has negative impacts on human health. Adsorption is an efficient method to remove pollutants from contaminated water, and dolomite is a natural mineral that can be easily obtained in large quantities. This study investigated the applicability of dolomite for removing methylene blue (MB) from water using a surfactant-assisted procedure. The experimental conditions for the best removal of MB by dolomite were established through batch adsorption studies. The findings showed that dolomite effectively adsorbs MB and could be used as a cost-effective sorbent in wastewater treatment.

It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
