Summary: The incorporation of different metal types (Fe, Al, Mn, Zn, and Cu) on MCM-48 synthesized by the direct sol-gel method was investigated. It was found that Fe, Mn, and Zn incorporated into the framework of MCM-48 resulted in increased thickness of the pore wall, leading to better thermal stability. On the other hand, the agglomeration of metal oxides and the nature of aluminum led to a decreased thickness of the pore wall and lower thermal stability in MCM-48.

Summary: A composite material PdZnAl(HT)/MCM-48 was synthesized as a catalyst for steam reforming of methanol, which exhibited high activity and stability. The PdZn(Al)O/MCM-48-2 catalyst obtained after calcining and reducing showed a large surface area and small PdZn particle size, facilitating efficient conversion of methanol to hydrogen. Carbonaceous deposits on the catalyst surface caused deactivation, but the deactivated catalyst could be regenerated by calcination and reduction.

Summary: The influence of various introduction ways of Pt on the catalytic oxidation performance of toluene was investigated on Pt supported on MCM-48 prepared by four different methods. It was found that Pt/M48-PG prepared via the post-grafting method exhibited the highest Pt content, resulting in the lowest T-90 and the highest TOF. Characterization results showed that the amine functional groups grafted onto the support's surface contributed to the high actual loading efficiency and dispersion of Pt.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
