Lyocell fiber has emerged as an important class of regenerated cellulose that is produced based on the N-methyl morpholine-N-oxide (NMMO) dissolution method, and it has unique properties compared to viscose fiber. The NMMO technology provides a simple, resource-conserving, and environmentally friendly method for producing regenerated cellulose fiber. In this paper, the manufacturing process, environmental impact, and product quality of lyocell fiber are reviewed and compared with those of the conventional viscose fiber.

Cellulose nanopaper (CNP) was successfully demonstrated for enhanced efficiency and effectively wide-angle light capturing of organic solar cells (OSCs).

In article number 2001494, Lihui Chen, Xinhua Ouyang, and co‐workers successfully demonstrate secondary bonds to modify conjugate‐blocked linkages of biomass‐derived lignin or the electron transfer layer of organic solar cells. The enhanced conductivity, resisted phase separation, and repaired the contact makes it valuable for organic electronics.
