AIChE Journal, EarlyView.Abstract Covalent organic framework (COF) membranes are promising for eco‐friendly separations, but precise control of pore size at the angstrom level has been challenging, limiting their application in gas separation. This study introduces a pore redistribution method to reduce pore size to the sub‐nanometer range in single‐phase COF membranes.

Food Science &Nutrition, Volume 11, Issue 1, Page 390-407, January 2023., 2023 COPD aggravates AS, possibly through the destruction of pulmonary microvascular barrier function; thus, lung inflammation triggers systemic inflammation. In treating COPD with AS, TXL enhances the antiatherosclerotic effect of Ato, protecting the pulmonary microvascular barrier.
