Substituent‐Dependent SERS Kinetics of Citrate‐Stabilized Gold Nanoparticles: Balancing Hotspot Formation and Colloidal Flocculation

open access: yesChemistry – A European Journal, EarlyView.
Reporter chemistry controls the operational window of liquid‐phase SERS. Para‐substituted benzenethiols induce distinct AuNPs colloidal regimes, ranging from delayed but stable hotspot formation to rapid flocculation‐dominated signal decay. The balance between SERS‐active‐state formation and colloidal loss defines whether a reporter provides reliable ...

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.

CytoScan: Automated Detection of Technical Anomalies for Cytometry Quality Control

open access: yesCytometry Part A, EarlyView.
ABSTRACT Studies evaluating cellular phenotypes by cytometry techniques are increasingly facing analytical challenges due to the multitudes of samples and parameters that are evaluated concurrently. Spurious technical effects resulting from a lack of standardization can affect marker distributions and further complicate multi‐sample analyses.

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.
