Stable calcium metal batteries enabled by ionic covalent organic framework artificial protection layers

open access: yesInfoMat, EarlyView.
Irreversible calcium (Ca) plating and stripping pose significant challenges for Ca metal batteries due to the formation of an ion‐insulating passivation layer. This study demonstrates that ionic covalent organic frameworks (iCOFs) serve as effective artificial protective layers for Ca metal anodes, facilitating rapid Ca2+ transport and promoting ...

Effect of Subphase Ions on Multilayer Deposition of an Anionic Gemini Surfactant on Solid Substrates

open access: yesJournal of Surfactants and Detergents, EarlyView.
Multilayer formation in Gemini surfactant films with subphase ions. ABSTRACT A recently reported anionic Gemini surfactant belonging to the “minimal linker” family has been shown to form closely packed crystalline monolayers at the air–water interface, like a simple fatty acid, but its ability to deposit onto solid substrates as multilayer films ...

Microwave‐Assisted Synthesis of Chitosan–Iron Oxide (CS@Fe3O4) Nanocomposite for Removal of Cationic and Anionic Dyes

open access: yesMacromolecular Materials and Engineering, EarlyView.
A novel chitosan–iron oxide nanocomposite synthesized via microwave‐assisted technique demonstrates rapid and efficient removal of both cationic and anionic dyes from water. Comprehensive characterization and adsorption studies reveal high capacity, reusable performance, and robust removal mechanisms, positioning this material as a promising, scalable ...
