The bidirectional regulation mechanism of NMMO concentration change on cellulose dissolution and regeneration

Cellulose, 2023
Abstract The dissolution and regeneration process of cellulose molecules in NMMO aqueous solution was studied by molecular dynamics (MD) simulation. The effect of the concentration of NMMO aqueous solution on the structure of cellulose was discussed.

A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, Volume 64, Issue 16, Page 3364-3381, 15 August 2026.
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 ...

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 25, 4 July 2026.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.
