A new kind of flex-activated mechanophore, N-heterocyclic carbene–carbodiimide adduct (NHC-CDI), was developed as a platform to release different NHCs under mechanical load. The polymeric materials containing NHC-CDI can be subjected multiple compression cycles and successively NHCs, which have potential utilized self-healing, self-strengthening self-reporting materials.

Gold nanoparticles (AuNPs) are employed in numerous applications, including optics, biosensing, and catalysis. In their Communication (e202212459), Petra S. Dittrich et al. demonstrate the stabilizer-free electrochemical synthesis of AuNPs inside nanoliter-sized reactors. with sizes range 30 to 100 nm were produced without need for additional capping agents. This method opens way fine-tune prod...
