Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting
Macromolecular Rapid Communications, EarlyView.Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality
Journal of Polymer Science, EarlyView.Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

The possibility of controlling formation and cleavage reactions of HexA during kraft pulping [PDF]
, 2006 During kraft pulping, the side groups in the xylan backbone, 4-O-methyl-D-glucuronic acid (MeGlcA), are partly converted to hexenuronic acid (HexA). Simultaneously, degradation reactions of these side groups take place.
