The transition from the fixed to the fluidized state of well‐mixed binary‐solid mixtures in a liquid upflow

AIChE Journal, EarlyView.
Abstract In this work, an investigation of the transition from fixed to fluidized state of initially homogeneous binary‐solid mixtures due to an upward liquid flux was carried out. Like for analogous gas systems, it was confirmed that the full transition occurs over a range of fluid velocities, from the initial to the final fluidization velocity. Based

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.

Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors

Advanced Intelligent Systems, EarlyView.
Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.
