Solvent effect on the production of spherical lignin nanoparticles

Abstract

Controlling the self-assembly behaviors of soluble lignin oligomers is key to construct uniformly spherical lignin nanoparticles (LNPs) and benefit to their specific applications. Herein, several H2O-organic solvent systems were selected...

Preparation of homogeneous lignin nanoparticles by efficient extraction of lignin and modification of its molecular structure using a functional deep eutectic solvent containing γ-valerolactone

“…LNPs were prepared by an anti-solvent method. 53 With the introduction of water, the hydrophobic structure of lignin (benzene ring, side chain structure) was driven by π–π interactions to aggregate inward to reduce the surface tension. 54 Spherical particles were formed by the inward aggregation of hydrophobic groups and the outward orientation of hydrophilic groups (–OH, –COOH) (Fig.…”

Balance of Lignin Light-Color and UV-Shielding Properties: Pyruvic Acid Fractionation for Green Sunscreen Formulations

“…Furthermore, the polarity of the PA and the hydrogen bonding between the free oligosaccharides contribute to the rough surface of the PDL colloidal spheres. P50T100t60, with its high carbohydrate content, spatial resistance, and solvent hydrogen bonding, resulted in larger and more irregularly shaped colloidal spheres …”

“…P50T100t60, with its high carbohydrate content, spatial resistance, and solvent hydrogen bonding, resulted in larger and more irregularly shaped colloidal spheres. 37 Color of Lignin. Color analysis of PDL was conducted using the CIE standard (L* a* b*) to determine its practical applicability.…”

Composite fiber as a multifunctional catalyst support for the upgradation of lignin-based chemicals

“…References to limitations and parameter settings for the simulation process can be found in the literature. 38 The analysis and visualization of simulated trajectories were performed using Visual Molecular Dynamics (VMD) software 39 and GROMACS built-in modules. Thermal stability was investigated by thermogravimetric analysis (TGA) with a heating rate of 10 °C min −1 under a N 2 atmosphere using the thermo-gravimetric analyzer TG 209 F1.…”
