Results revealed that formic acid treatment resulted in oxidative cleavage of bonds in the lignin macromolecule, leading to formation of oligomers of …
Lignin fills the spaces in the cell wall between cellulose, hemicellulose, and pectin components, especially in vascular and support tissues: xylem tracheids, vessel elements and sclereid cells. Lignin plays a crucial part in conducting water and aqueous nutrients in plant stems. The polysaccharide components of plant cell walls are highly hydrophilic and thus permeable to water, whereas lignin is more hydrophobic. The crosslinking of polysaccharides by lignin is an obstacl… NettetWechat. Abstract.

NettetSimultaneously, the distinctive lignin functional groups (C O, OH, C–O–C) show strong electroactive redox properties towards Li + ions. Owing to that, a primary Li/lignin cell could achieve the maximum capacity of ∼600 mA h g −1. Heretofore, this review presents a brief summary of lignin use in diverse Li-based systems.
