Extended Oxygen Delignification with the Oxy TracTM Process
Many mills have adopted oxygen delignification systems in order to decrease chemical consumption in a bleaching plant since 1970's.Generally, the maximum delignification obtained by oxygen delignification system keeping pulp strength has been considered about 50% for softwood pulp because possible delignification by oxygen is limited to certain groups ...

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,
