Strong protic acids catalyze intermolecular transesterification in reversible polyester syntheses even at low temperatures (109 °C), an important aspect not considered in the original Jacobson–Stockmayer theory of reversible polycondensations.

Lignosulfonates are industrial biorefinery products that are characterized by significant variability and heterogeneity in their structural composition. Typically, they exhibit high dispersities in...
Lignin is a highly underused resource. The complex and heterogeneous structure poses a challenge to industry and science. Problems are high polydispersity, high-molar-mass and insufficient functional groups. In this article, we present a mechanochemi

We present the optical sensing of phthalate esters (PAEs), a group of endocrine-disrupting chemicals. The sensing takes place as changes in the fluorescence emission intensity of aminopyrene covalently bound to the organic ligands of the metal–orga
