Summary: In this study, a new biosensing membrane was designed for the development of an electrochemical glucose biosensor. The biosensor utilized a chitosan-based hydrogel that encapsulated glucose oxidase enzyme (GOx) and was crosslinked using glutaraldehyde. The stability of the biosensors was investigated under different storage conditions and it was found that they maintained stability for over six months in certain specific conditions. Catalase was also included to protect the biosensing membranes from enzymatic reaction by-products, thereby enhancing the lifetime of the biosensor.

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 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: The paper discusses the impact of MCM-41 mesoporous silica on the properties of cement matrix. It was found that the optimal content of MCM-41 is between 0.5% and 1%, as excess silica may disrupt the proper hydration process. The research indicates a high application potential of MCM-41 as an additive in cement.

Summary: Water sources with high uranium prevalence pose potential health risks. The development of efficient uranium scavenging water treatment techniques is of great importance. NH2-MCM-41(MCM-a) was synthesized and grafted using salicylaldehyde (MCM-s) and 3-hydroxybenzoic acid (MCM-hb). The results showed that MCM-s had the highest adsorption capacity under the optimum conditions. The thermodynamic parameters indicated the feasibility of the adsorption process. MCMs exhibit rapid adsorption rate, high adsorption efficiency, and regeneration ability, making them promising for uranium removal in water treatment.

Summary: Based on the structural advantages of MOFs in enzyme mimics and enzyme immobilization, this study constructed Hemin@PCN-222(Mn) through an in-situ hydrothermal route. The resulting Hemin@PCN-222(Mn) showed excellent peroxidase-like activities compared to single Hemin and PCN-222(Mn). After optimizing the immobilization conditions, the resulting GOx@hemin@PCN-222(Mn) exhibited high efficiency and stability in the cascade reaction of glucose oxidation and biosensing.
