Multiresponsive Color‐Tunable Phosphorescence With Matrix‐Confined Clusters

open access: yesAggregate, EarlyView.
The molecule with cluster‐triggered emission mechanisms is embedded in polymer matrix, the phosphorescence properties of multiclusters are size‐dependent and exhibit different responses to various stimuli, including temperature, concentration, and excitation, which synergistically induce color‐range tunable time‐dependent phosphorescence color behavior.

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.
