Front Cover: Selective Rubidium Recovery Using Zeolitic Potassium Hexacyanoferrate Nanomaterial Electrode in Capacitive Deionization (Small Struct. 1/2026)

Year: 2025

Type: paratext

Abstract: Selective Rubidium Recovery Rubidium (Rb+), vital for defence and high-technology application, is rare in ores. Seawater offers a renewable source, yet Rb+ separation is difficult. In their Research Article (10.1002/sstr.202500273), Gayathri Naidu and co-workers develop an electrode with KCoFC@ZIF-AC nanomaterial that electrochemically captures Rb+ via K+/Rb+ exchange, showing high Rb+ selectivity, reusability, and scalability.
