A Sustainable and Low‐Cost Zn‐Lignosulfonate Redox Flow Battery

Batteries &Supercaps, EarlyView.
A cost‐effective Zn/lignosulfonate (NaLS) hybrid flow battery using 20 kDa NaLS delivers 3.52 Ah L−1 at 30 mM, with an average discharge voltage of 1.01 V, outperforming smaller NaLS. This sustainable design leverages industrial and bio‐based lignosulfonates, cheaper size exclusion membrane, and abundant Zn for ecofriendly, scalable energy storage ...

Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction

ChemistryEurope, EarlyView.
This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.

Gold(I)‐Catalyzed Domino Cyclization for the Construction of Trispirocyclic Cyclohexanes

ChemistryEurope, EarlyView.
We describe herein a series of intricate trispirocyclic architectures that have been synthesized from readily available substrates through an operationally simple one‐pot transformation under mild conditions. An unprecedented gold(I)‐catalyzed domino cyclization involving 2‐ethynylbenzyl alcohol derivatives and heterocyclic α,β‐unsaturated imines ...
