Advancing Upcycling and Regeneration of Spent LiFePO4: Failure Mechanisms and Recovery Strategies
Carbon Energy, EarlyView.This review studies the failure mechanism to promote the upcycling regeneration of spent lithium iron phosphate (S‐LFP). It first summarizes the failure mechanisms of LFP batteries revealed via advanced characterization technologies and then explores the respective advantages and challenges of hydrometallurgy and direct regeneration methods.

High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress
Chemistry – A European Journal, EarlyView.ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

Chemistry – A European Journal, EarlyView.New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor
The Canadian Journal of Chemical Engineering, EarlyView.A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).
