While CNF dispersibility can now be adjusted by selecting appropriate raw material species or employing specific chemical pretreatments, controlling defects remains a challenge. In our previous study, we found that the dent defects

This material typically has a high lignin content, dependent upon the pretreatment method. Steam-explosion significantly disrupts the cell wall from the autocatalyzed breakage of lignin and carbohydrate linkages allowing lignin to rearrange

However, our lifestyle also generates significant problems due to the way we use polymers. Most polymers are discarded after use, rarely recycled, and end up in landfills, rivers, and oceans. This fate exemplifies the current linear, fossil-based

The resulting prehydrolysis liquors are currently incinerated at low efficiency, hampering pulp production. Herein, the preparation and characterization of a polymer synthesized from hemicellulose derived monomers is described, offering an alternative to incineration. The polymer was prepared without solvent at room temperature,

These composites contain a superposition of order and disorder, which makes them difficult to design optimize. Similar pairing or non-randomness and stochasticity is also present in high-performance load-bearing, mass-transporting, ion-selective, and optically-active

Moreover, plant polysaccharide structures also influence their interactions and assembly in the cell wall, and consequently, properties such as strength of wood. The action of enzymes on biomass may be influenced not only by the structure of the polysaccharide but also the molecular architecture of the
