Consequences of Monomer Impurities on Network Characteristics and Dynamic Mechanical Behavior of an Eugenol‐Based Covalent Adaptable Network

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
How robust is the dynamic exchange behavior of covalent adaptable networks (CAN) toward monomer impurities? This study simulates the unnoticed incorporation of a monomer impurity into a CAN and determines the consequences for synthesis and network characteristics, focusing especially on the dynamic mechanical behavior at both the micro‐ and macroscale.

Light Meets Nature: Cellulose Cluster as a Natural Photoantimicrobial Agent

Small Structures, Volume 7, Issue 6, June 2026.
Cellulose derivatives exhibit cluster‐triggered emission, generating singlet oxygen through long‐lived excitonic states without conventional chromophores. This work reveals strong photoantimicrobial activity against Gram‐positive bacteria, transforming cellulose from an inactive excipient into an effective photodynamic agent.
