Stable Isotope Reference Materials and Scale Definitions—Outcomes of the 2024 IAEA Experts Meeting

Rapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.
ABSTRACT The participants of the 12th International Atomic Energy Agency (IAEA) meeting on stable isotope reference materials reached a consensus, acknowledging the existence and use of two carbon isotope delta scales: the VPDB (Vienna Peedee belemnite) scale and the VPDB‐LSVEC (LSVEC ‐ lithium carbonate prepared by H. J. Svec).

Structural Insights Into Aluminum‐Doped Manganese Dioxides as Promising Materials for Direct Lithium Extraction: Modeling and Mechanism Study

Advanced Materials Interfaces, Volume 12, Issue 11, June 9, 2025.
A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...
