C-lignin is a homo-biopolymer, being made up of caffeyl alcohol exclusively. There is significant interest in developing efficient and selective catalyst for depolymerization of C-lignin, as it represents an ideal feedstock for producing catechol derivatives. Here we report an atomically dispersed Ru ...
MANUFACTURE OF GRAFT COPOLYMER FROM LIGNIN AND VINYL MONOMERPURPOSE: To produce a lignin graft copolymer made of a lignin-containing material, i.e., lignin, grafted wood, grafted wood fiber, or grafted pulp, by preparing an environment free of O2 and forming a reaction mixture made up of a...
Based on its molecular structure, lignin is made up of three main components that are connected by a variety of bonds [29]. As per the nature of LCBM, the structure of lignin is also variable, and the process of degradation powerfully dependent on its constitution. Proper structural ...

Explore the definition of lignin, learn the unique structure of lignin, the function of lignin in plants, and how humans have come to rely on this...
All of these forces are relatively weak and therefore these hydrogels have a tendency to disintegrate over time9,10. By contrast, chemical hydrogels, which are made of rigid molecules like lignin, are crosslinked with covalent bonds thus being significantly more stable14,15. Even though most of ...
The resistance to degradation of lignin, like the difficulties encountered in the context of its extraction, are probably due to the complex structure of this polymer, which is made up of ether bonds and carbon-carbon bonds between the monomers, as well as to the numerous chemical bonds which...
Background: Due to the unsustainable consumption of fossil resources, great efforts have been made to convert lignocellulose into bioethanol and commodity organic compounds through biological methods. The conversion of cellulose is impeded by the compactness of plant cell wall matrix and crystalline struc...
Developing novel techniques to convert lignin into sustainable chemicals and functional materials is a critical route toward the high-value utilization of
HTT was also optimized for the valorization of polymeric and oligomeric hemicelluloses.5 Nevertheless, few attempts have been made related to lignin valorization in this process. Recently, we have suggested a lignin-centered HTT process42 that showed a proof-of-concept for the extraction of pure ...
