Tailoring Zn‐ion Solvation Structures for Enhanced Durability and Efficiency in Zinc–Bromine Flow Batteries

open access: yesAngewandte Chemie, EarlyView.
This study presents a strategy to improve aqueous zinc‐bromine flow batteries (ZBFBs) by tuning Zn2+ solvation structures using a hydrogen bond‐accepting cosolvent. This approach stabilizes pH, suppresses hydrogen evolution, and enhances Zn plating/stripping reversibility—offering a pathway to durable, high‐efficiency ZBFBs for grid‐scale energy ...

Mechanical and Electrical Properties of Free‐standing Polycrystal Diamond Membranes

open access: yesAdvanced Science, EarlyView.
We demonstrate a novel approach for synthesizing free‐standing and transferable polycrystalline diamond membranes (PCDm). Two types of PCDm cantilevers—Top‐Surface‐Up (TSU) and Bottom‐Surface‐Up (BSU)—are fabricated and systematically analyzed for mechanical and electrical properties, including elastic modulus, Bandgap, sheet resistance under the ...
