Hydrothermal Depolymerisation of Kraft Lignin: The Influence of Capping Agents and Residence Time [Elektronisk resurs] [PDF]
, 2023 Lignin, the aromatic macromolecule found in wood and other lignocellulosic biomass, is envisioned as a future renewable source of aromatic compounds that can be used as, for example, chemicals, fuel additives and resins.

, 2022 Many materials, man-made and natural, have a composite structure, i.e. they comprise two or more constituent materials with distinct differences. Concrete is a common example. It consists of sand or gravel, cement and water. Wood is also a composite. It has strong, crystalline cellulose structures glued together by hemicelluloses and lignin. The unique

Carbon Energy, EarlyView.A scalable strategy utilizing native impurities in bamboo lignin black liquor is proposed to construct a closed‐pore, rich hard carbon. Controlled impurity removal and high‐temperature reconstruction enable the conversion of open pores into abundant closed pores, thereby promoting sodium cluster storage.

Lignin studies of transgenic Norway spruce [PDF]
, 2006 An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...
