Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness [PDF]

open access: yesChemSusChem
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Synthesis of trimethylolpropane esters of oleic acid by Lipoprime 50T

open access: yesJournal of Industrial Microbiology & Biotechnology, 2011
The ability of the commercial lipolytic enzyme Lipoprime 50T to catalyze the biotechnologically important synthesis of the biodegradable and environmentally acceptable trimethylolpropane (2-ethyl-2-(hydroxymethyl)-1,3-propanediol) ester of oleic acid was investigated. Simple and accurate thin-layer chromatography and computer analysis methods were used
