Acetylation of phenol with Al-MCM-41
Catalysis Communications, 2001 Abstract Mesoporous Al-MCM-41 molecular sieve materials with three different SiO2/Al2O3 ratios were used as catalysts for the acetylation of phenol with acetic anhydride and acetic acid as the acetylating agents. The reactions gave 100% ortho-selectivity with acetic acid being the more effective acylating agent. The reactions were run under different

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression
Hepatology, EarlyView., 2022 Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.
