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

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.

Hindered cracking in colloidal suspension coatings via evaporation‐driven lyotropic liquid crystals

AIChE Journal, EarlyView.
Abstract We demonstrate that lyotropic liquid crystalline (LC) phases, formed by the molecular interactions between 1‐glyceryl monooleyl ether (GME) and water, offer new pathways for producing crack‐free particulate films from colloidal suspensions. Drying experiments on titanium dioxide‐ethanol‐water‐GME suspension systems revealed a 15‐fold increase ...

Reinforcement learning for optimal control of stochastic nonlinear systems

AIChE Journal, EarlyView.
Abstract A reinforcement learning (RL) approach is developed in this work for nonlinear systems under stochastic uncertainty. A stochastic control Lyapunov function (SCLF) candidate is first constructed using neural networks (NNs) as an approximator to the value function, and then a control policy designed using this SCLF is developed to ensure the ...

Physics‐informed neural networks (PINNs) for high‐resolutional prediction of shear stress on cells in suspension culture

AIChE Journal, EarlyView.
Abstract The effect of shear stress on cell behaviors should be considered for designing the suspension culture of mammalian cells. Computational flow dynamics (CFD) is a promising tool for estimating shear stress on cells, but the accuracy is limited due to resolution limitations.

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

AIChE 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.
