Evaluation of Organosolv Lignin as an Oxidation Inhibitor in Bitumen [PDF]
Molecules, 2020 Organosolv lignin, a natural polymer, has been used in this study as an oxidation inhibitor in bitumen. Particularly, the effect of oxidative aging on the chemical compositional changes and on the rheology of bituminous binders with organosolv lignin and

Unraveling the Role of Lignin Oligomers Functionality for the Synthesis of Nonisocyanate Polyurethanes. [PDF]
ChemSusChemThis study reports the synthesis of bio‐based nonisocyanate polyhydroxyurethanes from crude lignins and depolymerized lignin oligomers. The structure–properties relationships were largely explored and highlighted the key role of lignin functionality on the physical properties of the materials. Lignins are the main source of aromatic compounds in nature.

Atomistic Origins of Biomass Recalcitrance in Organosolv Pretreatment
Chemical Engineering Science, 2022 Secondary plant cell walls are made from three common biopolymers, cellulose, lignin, and hemicellulose, representing a critical feedstock for sustainable biomaterial production. Separating lignocellulosic biomass components for use in tailored sustainable energy and materials applications is challenging, as the biopolymers are in close proximity ...
