Front Cover: Stabilization of Verdigris Pigment on Paper: Evaluation of Antioxidants Under Mild Accelerated Degradation Conditions (ChemPlusChem 5/2025)

Abstract

The cover image presents various mock-up paper samples containing verdigris pigment, shown either before (below) or after accelerated thermal degradation (above). The samples are either untreated or treated with one of two antioxidants (tetrabutylammonium bromide or 1-H benzotriazole), with their 3D molecular models depicted in the image. Additionally, the image highlights key results, including SEC chromatograms, as well as XPS and Raman spectra of the samples. Cover picture design by Maj Blatnik.
