Ultrafast process of microwave-assisted deep eutectic solvent to improve properties of bamboo dissolving pulp

Chao Duan et al.

Summary: In this work, an ultrafast microwave-assisted deep eutectic solvent (MW-DES) process was proposed for viscosity control and reactivity enhancement in the production of high-quality cellulose products. The MW-DES process achieved simultaneous fiber swelling and cellulose depolymerization, resulting in a significant decrease in pulp viscosity and increase in reactivity. The DES used in the process showed high reusability and chemical stability, providing a simple, sustainable, and effective alternative for upgrading dissolving pulp from non-wood materials such as bamboo.

Acidic deep eutectic solvent treatment for viscosity control and reactivity enhancement of bamboo dissolving pulp

Chao Duan et al.

Summary: This study demonstrated a green process using deep eutectic solvent (DES) treatment to improve the properties of bamboo dissolving pulp. The results showed that the most effective DES was an acidic one called choline chloride-oxalic acid. Under the optimal treatment conditions, the viscosity of the pulp decreased and the reactivity increased. The positive results were attributed to the depolymerization of cellulose chain and improved fiber swelling and reaction efficiency during DES treatment.

Green and energy-efficient extraction of cellulose nano-fibrils from rice straw and its coating to improve functional properties of rice straw paperboard made via refiner mechanical pulping

Shashank Saini et al.

Summary: A unique approach was used to convert rice straw from the Indian state of Haryana into paperboard coated with cellulose nano fibrils. The extracted nano fibrils did not alter the crystalline arrangement of cellulose, and the coated paperboard showed improved properties such as reduced roughness, increased water vapor barrier, and grease resistance.

Chemically Stabilized and Functionalized 2D-MXene with Deep Eutectic Solvents as Versatile Dispersion Medium

Jeonghui Kim et al.

Summary: 2D transition metal carbides and nitrides, known as MXenes, are typically synthesized and delaminated in different solutions, but chemical treatments in solution can affect their structures and properties. By utilizing DESs, long-term stable dispersion of Ti3C2Tx nanosheets is achieved, preventing oxidation and enhancing performance as electrodes for electrochemical capacitors.

Deep eutectic solvent recycling to prepare high purity dissolving pulp

Yuanhang Chen et al.

Summary: A novel acid-based deep eutectic solvent (DES) recycling process was developed for pretreating eucalyptus wood chips to produce high-purity dissolving pulp. The extracted lignin and xylan in DES were recovered and the solvent regenerated through precipitation and evaporation, leading to a high-purity dissolving pulp with improved properties. The DES pretreatment showed promise in efficiently utilizing biomass for dissolving pulp production, highlighting its potential in the biorefinery concept.
