Lewis acid‐driven interlayer shifting in sub‐nm 2D covalent organic framework membranes for hydrogen purification

open access: yesAIChE 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.

Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion

open access: yesAIChE Journal, EarlyView.
Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

Investigating Performance Properties of Three New Types of UF Membranes for Carwash Sector Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and its derivatives were used to prepare new types of UF membranes. Membranes had a high degree of removal efficiency of pollutants from carwash wastewater. The morphological SEM cross‐sectional of the membranes reveals to be porous ultrafiltration membranes.
