Between theft and treason: latrocinium in Carolingian capitularies

Early Medieval Europe, Volume 33, Issue 3, Page 367-390, August 2025.
Suppressing robbery, latrocinium, was a priority for Charlemagne, Louis the Pious, Charles the Bald, and Louis II at key political moments. Latrones were conceptualized as ordinary thieves, as highway robbers, and as threats to peace and security. In capitularies, latrocinium was implicitly and explicitly associated with infidelity.

Dissociation Constant (Kd) Measurement for Small‐Molecule Binding Aptamers: Homogeneous Assay Methods and Critical Evaluations

Small Methods, Volume 9, Issue 6, June 20, 2025.
The characteristics of aptamer is most commonly represented by the dissociation constant (Kd), which is critical for aptamer optimization. Here, the assays used to evaluate Kd, including labeled and label‐free assays, are evaluated and suggestions are made to ensure that true values are obtained, while other methods are cautioned.

Photoredox‐Autokatalyse: Auf dem Weg zu einer Bibliothek allgemein anwendbarer reduktiver Sulfonamid‐Photokatalysatoren

Angewandte Chemie, Volume 137, Issue 22, May 26, 2025.
Photoredox‐Autokatalyse ermöglicht den Zugang zu cyclischen Biarylsulfonamiden (BASNs) ohne exogenen Photokatalysator. Neben einem wichtigen Beitrag zur Grundlagenforschung hat die Entdeckung der Photoredox‐Autokatalyse auch zu weiteren praktischen Anwendungen geführt, wie der Entdeckung von BASNs als neuartige, wirksame und leicht zugängliche ...
