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.

Could the chemical industry mitigate rapid global cooling from a catastrophic volcanic eruption?

open access: yesAIChE Journal, EarlyView.
Abstract Estimates based on historical data place the probability of a catastrophic volcanic eruption in the next 100 years at around one in six. Large volcanic eruptions can lead to significant global cooling for 2–4 years, with potentially devastating impacts on global agriculture.

Efficient heat integration within discretely heat integrated distillation columns using liquid injection

open access: yesAIChE Journal, EarlyView.
Abstract Electrification of distillation processes through discretely heat integrated distillation columns (D‐HIDiC) is an effective approach to enhance energy efficiency and lower carbon emissions. For separating systems with high temperature lift, multi‐stage compression and inter‐stage cooling are necessary to link the high‐pressure rectifier and ...

Civil Procedure in Classical Rome: Having an audience with the magistrate [PDF]

open access: yes, 2010
During the classical period of Roman law, civil lawsuits were divided into two proceedings: a brief proceeding before the magistrate, who decided certain preliminary matters, and a longer proceeding before a judge, who tried the case.

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.

Cake formation in the filtration of associative microgel suspensions

open access: yesAIChE Journal, EarlyView.
Abstract In this work, we investigate the jamming behavior of associative microgel suspensions used as fluid loss additives in model porous media. We first construct a phase diagram using drying experiments, followed by characterization of the suspensions' rheology and the permeability of the filter cakes at maximum microgel concentration.
