How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

Highly Efficient Sky‐Blue Perovskite Quantum Dot Light‐Emitting Diodes via Ligand‐Assisted Trap‐State Passivation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,
