Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Durable Biofouling‐Resistant Coated Fabric Based on Aerogel/Polyurethane for Marine Applications

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
A multilayer composite protective fabric (PUC‐CME/KF) is developed by integrating carboxymethyl chitosan/coral extract aerogel and capsaicin‐loaded polyurethane onto a knitted substrate. The material exhibits exceptional extensibility (1963% elongation at break) and sustained capsaicin release.
