Palladacarboxamide Capping Reagents for Carbon Isotope Labeling and Pharmaceutical Diversification
Angewandte Chemie, EarlyView.Herein, we present a method for carbon isotope labeling of arylamides via the coupling of air‐stable palladium carboxamide complexes and boronic ester/acids. A wide variety of functionalized boronic esters and acids have been coupled with simple palladium carboxamides complexes.

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens
Advanced Healthcare Materials, EarlyView.High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials
Advanced Healthcare Materials, EarlyView.Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...
