Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

A Robust Metal‐Organic Framework With ‘Molecular Gates’ for Efficient Separation of Ethane From Ethylene

Angewandte Chemie, EarlyView.
By installing an amino‐based molecular gate at a specific site within a robust zinc‐adenine framework, temperature‐tunable inversion of C2H6/C2H4 selectivity is achieved, enabling single‐step on‐stream production of polymer‐grade ethylene. ABSTRACT Ethane‐selective sorbents can enable single‐step purification of ethylene but remain elusive to date.

Exploring Quantum Support Vector Regression for Predicting Hydrogen Storage Capacity of Nanoporous Materials

Advanced Intelligent Discovery, EarlyView.
In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Electrolyte Covalent Organic Frameworks for Exceptional Potassium Ion Conduction

Angewandte Chemie, EarlyView.
One‐pot polymerization of monomers with oligo(ethylene oxide) side chains of different lengths creates electrolyte covalent organic frameworks with well‐defined K+‐electrolyte pathways in 1D pores for K+ conduction. The materials promote K+ conduction exponentially with the side chain length, achieve exceptional conductivity, and enable frictionless ...

Porous Phenazine‐bridged Tetraoxa[8]Circulenes for Selective Gold Recovery and Heterogeneous Catalysis

Angewandte Chemie, EarlyView.
Gold recycling from electronic waste using porous materials is an emerging concept to reduce the environmental impact of gold mining. In this work, we report the synthesis of a highly porous phenazine‐derived tetraoxa[8]circulene polymer and its utilization in gold capture and heterogeneous catalysis.
