Summary: Intercalated layered materials provide distinctive properties and serve as precursors for important 2D materials. This study presents a structural editing protocol for layered carbides (MAX phases) and their 2D derivatives (MXenes). Gap-opening and species-intercalating stages were mediated by chemical scissors and intercalants, resulting in a large family of MAX phases with unconventional elements and structures, as well as MXenes with versatile terminals. The reconstruction of MAX phases and a family of metal-intercalated 2D carbides may drive advances in fields ranging from energy to printed electronics.

Summary: LDHs are a type of cationic-layered solid that can be synthesized for various advanced functions, and in this work, an in-situ and patternable thin film synthesis of interconnected Zn-Cr LDH particles was successfully demonstrated at room temperature within minutes. The replacement of interlayer anion with perfluorooctanoate results in an increased interlayer sheet distance and the formation of a super-hydrophobic thin film capable of adsolubilizing and retaining organic guest molecules.

Summary: In order to address the issues of structural collapse and deactivation faced by LiAl-LDHs during desorption process, an interlayer anion regulation strategy was proposed. Through intercalation of PO4 3-, Li+ could be anchored into the vacancies of Al-O octahedron via high interlayer binding energy and strong electrostatic interaction, which improved the anti-elution deactivation ability of LiAl-LDHs. LiAl-LDH-P exhibited excellent Li+ adsorption capacity, selectivity, and reusability in Lop Nor brine, making it a promising adsorbent for Li+ extraction.

Summary: 2D layered materials have strong in-plane covalent chemical bonding and weak out-of-plane van der Waals interactions, allowing for the insertion of guest species without breaking the in-plane bonds. Intercalation materials can be tailored for variable compositional and structural features, enabling property modulation and applications in various technologies. Various intercalation methods and their effects on the crystal structure and properties of host materials are discussed, along with future research opportunities and challenges in the field.

Summary: In this study, the reactions of thiobenzamide or thioacetamide with different conditions were investigated. The influence of structure and medium features on product distribution was identified, including Eschenmoser coupling reaction, Hantzsch thiazole synthesis, and elimination to nitriles. The successful Eschenmoser coupling reaction relies on the optimum balance in acidity of nitrogen and carbon atoms of the intermediary alpha-thioiminium salts.
