Abstract:
... Herein, waste dyed wool was transferred into wool powder (WP) using a mechanical pulverization process. This powder benefits from the rich exposed functional groups and porous structures, which endow WP with capacities to adsorb odor molecules. WP milled for 6 h exhibited improved properties including homogeneous surfaces, small mean particle size (3.63 μm) and increased surface area, contributing ...

Abstract:
... Highly efficient breaking lignocellulose cell wall recalcitrance towards biomass valorization still remains a great challenge. In this work, we developed a very effective lignin-first strategy using diols for direct fractionation of light-color lignin, and resulting in enhancement of enzymatic saccharification of cellulose-rich residues. The isolated lignin fraction possessed relatively higher con ...
