Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

open access: yesAdvanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...

Connecting Local Structure, Strain and Ionic Transport in the Fast Sodium Ion Conductor Na11+xSn2+xP1−xS12

open access: yesAdvanced Energy Materials, EarlyView.
Substitution by larger polyanions in the fast sodium ion conductor Na11+xSn2+xP1−xS12 leads to inhomogeneities in the local structure which induces micro strain. The observed strain correlates with higher local diffusivities at room temperature and a lowering of the activation barriers for local ionic jumps which is explained by a widening of ...

Mechanoactivated Celite as a Catalyst for C‒H Bond Perfluoroalkylation and Other Radical Reactions

open access: yesAngewandte Chemie, EarlyView.
Biogenic materials naturally containing trace metals such as Celite or diatomaceous earth promote practical perfluoroalkylation of C─H bonds of (hetero)arenes and a double bond bromination with N‐bromosuccinimide upon mechanoactivation via ball milling. This conceptually broadens the scope of mechanoactivated solids beyond piezoelectric materials. This

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

open access: yesAdvanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

Mechanochemistry‐Driven Borrowing Hydrogen Processes for Ru‐Catalyzed N‐Alkylation: A Pathway to Enhanced Sustainability and Efficiency

open access: yesAngewandte Chemie, EarlyView.
This work pioneers a solvent‐free mechanochemical borrowing hydrogen (BH) strategy for the rapid and efficient N‐alkylation of amines and heterocycles. By removing harsh conditions and toxic reagents while employing a simple Ru catalyst, this approach redefines BH as a cleaner, more versatile, and sustainable platform for synthetic chemistry.
