Summary: The solubility parameter (SP) is crucial for indicating polarity and selecting solvents for dissolution. Recent studies have shown that ILs and DESs can efficiently solubilize lignocellulosic biomass for biofuel production. MD simulations are useful for predicting the solubility parameters of lignin, ILs, and DESs, and can be validated with experimental investigations. Additionally, the enthalpy of vaporization (Delta H-vap) of ILs/DESs is significantly higher than that of traditional organic solvents.

Summary: The study developed a bio-based antimicrobial resin for DLP printing, incorporating methacrylated O-acetyl-galactoglucomannan (GGMMA) and lignin nanoparticles embedded with silver nanoparticles (LNP@Ag) as a high-performance antimicrobial reagent. Through in situ reduction of silver nanoparticles and modulation of lignin polymerization degree, LNPs were upgraded for alkali-resistance. The encapsulation of LNP@Ag into GGMMA hydrogel did not alter its properties, enabling the fabrication of stable hydrogel constructs with high antimicrobial activity through layer-by-layer photocuring in DLP printing.

Summary: Efficient utilization of agricultural waste through deep eutectic solvents (DES) for lignin separation and valorization is of significant importance. Different DESs, including acidic and alkaline systems, were used to fractionate lignin from raw and hydrothermal tobacco stalk. Results showed that hydrothermal pretreatment improved the yields and molecular weights of recovered DES lignin. Acidic DES lignin exhibited fragmented and condensed structures with lower molecular weight, while alkaline DES lignin showed well-preserved structure with fewer hydroxyl groups. These lignins displayed structure-dependent nanoparticle size, excellent UV absorption, and antioxidant activity, providing a foundation for targeted valorization of lignin from agricultural waste.

Summary: The study investigated the dynamics of catechol in zeolite Beta, revealing that the presence of the second OH group in catechol significantly hinders its mobility due to stronger hydrogen bonding interactions with the Bronsted sites. Molecular dynamics simulations confirmed this increased immobility, showing lower translational diffusion coefficients for catechol compared to phenol in acidic zeolites. The study also found that catechol exhibits restricted and rapid rattling motion in the pore system of zeolite, indicating strong interaction of the molecules with the acid sites.

Summary: This study investigates the solvent effects on the intrinsic properties of spherical lignin nanoparticles (LNPs) and finds that LNPs prepared from aqueous acetone exhibit smaller size and higher uniformity compared to those prepared from aqueous tetrahydrofuran. Both LNPs are compact particles with relatively homogeneous density distribution and very low porosity in the internal structure, with stiffness independent of size and Young's modulus ranging from 0.3-4 GPa. The understanding gained in this study is crucial for designing LNPs with optimal performance in applications.

Summary: This research combines MD simulation and laboratory experiments to explore the influence of lignin on the thermodynamic characteristics, rheological properties, and molecular structure of bitumen. The findings show that lignin can improve the modulus, elastic recovery, and rutting resistance of bitumen at a macroscale view, while increasing density, shear viscosity, and modulus at a microscale perspective. However, the self-healing ability and fatigue performance of lignin modified bitumen are weakened with the increase of lignin dosage. The correlations between the microscale and macroscale properties of lignin modified bitumen indicate that the physical and rheological properties of bitumen depend significantly on its molecular structure.

Summary: Recent advances in developing sustainable, micro- and nanoscale materials from biobased resources have focused on utilizing lignin to strengthen the bioeconomy. However, there is a gap in the literature regarding the various interactions present during and after the formation of lignin micro- and nanoparticles (LPs). These interactions are influenced by the chemical composition, molecular weight distribution, and solvent/water polarity. Factors such as lignin concentration also play a role in nucleation and growth mechanisms, with LPs formed at low concentrations exhibiting larger particle sizes than those formed at higher concentrations.
