BioResources, 2013 The main challenge in the oxygen delignification process is the improvement of selectivity. To further understand the effect of the amount of hydroxyl radicals on the selectivity of oxygen delignification, in this work, the hydroxyl radicals were generated by the improved Fenton reaction system and were quantified by UV spectrophotometry.

Mill experience of oxygen delignification.
JAPAN TAPPI JOURNAL, 1988 The M-C oxygen delignification system for the eucalyptus line of our mill has started operation in January 1986.The Kappa number and viscosity reduction are around 49 % and 19% respectively.Also, the good results are shown in terms of brightness and dirt content.Whereas, the reduction of total effective chlorine consumption and COD in the bleaching ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
