Coordinative Ring-Opening Copolymerization of Limonene Carbamate and ε-Caprolactone Toward Phosgene- and Isocyanate-Free Polyesterurethane Block-Copolymers with Tunable Properties. [PDF]

open access: yesMacromol Rapid Commun
This study presents a sustainable, isocyanate‐ and phosgene‐free route to polyesterurethanes via coordinative ring‐opening copolymerization of limonene carbamate and ε‐caprolactone. The resulting block copolymers show tunable thermal, optical, and mechanical properties, offering a green alternative for advanced polyurethane materials.

Chemical Methods for Peptide and Protein Backbone Cleavage

open access: yesChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).
