Delignification Pathways for the Engineering of Nanostructured Wood

Small Structures, Volume 7, Issue 1, January 2026.
Delignification severity in wood is determined by experimental parameters that control the removal of noncellulosic components, thereby shaping the resulting chemistry and microstructure. Although delignification is crucial for engineered wood fabrication, quantitative guidelines spanning different chemistries and processes are lacking.
