Summary: This paper introduces the advantages of nanocellulose derived from lignocellulose materials, such as high strength, lightweight, biodegradability, and renewability. Due to the complex and dense cell wall structure and poor solubility in water and most solvents, lignocellulose materials are difficult to dissolve directly and utilize effectively in practical production. The pretreatment technology is discussed, which exposes the amorphous areas, eliminates unnecessary non-cellulose components, and facilitates the subsequent applications. Traditional and green solvents used in the pretreatment of lignocellulose materials, as well as their mechanisms, advantages, and disadvantages, are introduced. Furthermore, the mechanism, process, advantages, and potential applications of deep eutectic solvent as a pretreatment solvent are discussed, along with suggestions for the future use of green solvents in treating lignocellulose materials.

Summary: This study prepared chitosan (CS) composite films by selectively dissolving lignin using deep eutectic solvents (DES), and investigated the toughening effect of DES/lignin on CS film substrate and its mechanism. The addition of DES/lignin effectively improved the plasticity of CS film, resulting in a maximum elongation at break of 62.6% for the plasticized film, which was 12.5 times that of the CS film. FTIR and NMR analyses demonstrated that the molecules in the DES/lignin complex interacted with CS, breaking the hydrogen bonds between CS molecules, and then recombined with CS molecules via hydrogen bonding. This study shows the potential of DES/regenerated lignin in improving the toughness of CS films and provides insights for the modification of plasticity in CS films.

Summary: Lignin/ZnO composites were prepared using a simple one-pot method with urea and ZnCl2-deep eutectic solvent (U/ZnCl2-DES) as solvent and raw material. The interaction mechanism between lignin functional groups and DES was clarified by molecular dynamics simulation, and it was blended with waterborne polyurethane (WPU) to form a film for evaluating its feasibility in ultraviolet shielding. The results showed that lignin/ZnO composites with excellent ultraviolet shielding properties were successfully prepared, and enzymatic hydrolysis lignin (EHL) showed better compatibility with ZnO compared to lignosulfonate (SL). When the addition of EHL/ZnO-N12.5 complex was 1.5%, the WPU film had good mechanical properties, light transmission, and ultraviolet shielding.

Summary: Studies have focused on the use of deep eutectic solvents (DES) for pretreating biomass to enhance enzymatic efficiency, but little attention has been given to the subsequent processing of regenerated lignin. In this study, lignin nanoparticles (LNPs) were prepared from walnut shells through DES pretreatment and antisolvent precipitation. Three DESs were utilized and evaluated for enzymatic hydrolysis efficiency of cellulose solids and the yield and functional properties of LNPs. The results showed that the ChCl:TsOH:EG (1:1:2) DES pretreatment resulted in the conversion of 42.72% of lignin in walnut shells into LNPs with a particle size of 157.71 nm and zeta-potential of -24.85 mV. The pretreatment also improved the enzymatic efficiency by 2.6 times compared to untreated walnut shells. The LNPs prepared from ChCl:OA:EG (1:1:1) exhibited excellent stability (zeta-potential of -31.97 mV), antioxidant properties (radical scavenging rate of 61.43%), and a high content of functional groups. This study has important implications for the chemical processing of biomass and the preparation of LNPs.

Summary: In this study, we demonstrated the easy preparation of deep eutectic solvents (DESs) using various imidazolium iodides and iodine. The electrical conductivity of the DESs could be controlled by changing the mixture composition and imidazolium cation species. Especially, the DES composed of 1-ethyl-3-methylimidazolium iodide and iodine in a 1:4 molar ratio exhibited a high electrical conductivity of 70 mS cm-1, which was higher than that of the ionic liquid mixtures with iodine. The high electrical conductivity of DESs can be attributed to the Grotthuss mechanism in polyiodide based on viscosity results, Raman spectrum measurements, and quantum chemistry calculations.

Summary: Nanofluid has attracted attention as a heat transfer fluid due to its superior thermal conductivity and rheological properties. In this study, a novel one-step preparation method was developed using Cu(OH)(2) as a precursor and deep eutectic solvents (DESs) as dispersing medium to overcome the poor stability and short liquid range associated with traditional nanofluids. The as-prepared nanofluid exhibited extraordinary static stability for at least two months without sedimentation and wide liquid range due to the in-situ formed Cu2O nanoparticles in DESs under microwave irradiation. The nanofluid's structural analysis and thermophysical properties were comprehensively studied, revealing that the thermal conductivity was slightly affected by the presence of Cu2O nanoparticles at low mass fractions. Importantly, the DESs-based nanofluid demonstrated promising photothermal conversion with the addition of 0.1 wt% Cu2O nanoparticles. This study provides an important approach for preparing nanofluids with high static stability.

Summary: In this study, two robust constrained affine-projection-like M-estimate (CAPLM) adaptive filtering algorithms are proposed to address the lack of robustness to impulsive interference in the traditional constrained affine projection (CAP) algorithm and achieve unbiased output in certain applications. The algorithms, CAPLM-I and CAPLM-II, are obtained by defining a modified Huber function (MHF) based robust AP-like (APL) minimization problem with constraints and transforming it into two different unconstrained optimization problems using Lipschitz continuity and two different methods. Both CAPLM algorithms can avoid the computational complexity caused by inverting the input signal matrix in classical AP algorithm and achieve robustness to impulsive interference. The mean square stability and corresponding stable step size ranges are analyzed. Simulation results demonstrate that the proposed CAPLM-I and CAPLM-II algorithms perform well in impulsive noise environments for system identification and beamforming applications, with lower steady-state error and faster convergence speed compared to other algorithms.

Summary: The bandgap of (AlxGa1-x)(2)O-3 thin films can be modulated by varying the Al contents, resulting in high-performance photodetectors for solar-blind UV bands. The detection cut-off wavelengths and response peaks of the photodetectors can be tuned by changing the Al contents. The wide variations of the bandgap are mainly due to the upshift of the conduction band edges induced by Al 3s state hybridization.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
