Summary: In this research, a modified castor oil-based epoxy is synthesized and waste expanded polystyrene (EPS) is used as a filler in the improved biocomposite. The properties of the biocomposite are evaluated using response surface methodology and artificial neural networks. Chemical characterization and physical analysis of the biocomposite are performed. The results show that the use of modified castor oil increases the activation energy and reduces the petrochemical content in the biocomposite. The incorporation of waste EPS reduces production cost and density, while increasing thermal insulation and workability. A new model equation is developed to study the thermal decomposition behavior.

Summary: Six N-morpholinium dicationic ionic liquids with different linker lengths were synthesized and their thermal stability was assessed. It was found that NTf2 DILs are more stable than bromide DILs, and the decomposition time at a given conversion degree at 250 degrees C was used as an alternative stability parameter. The decomposition mechanism of the shortest member in the bromide series was investigated using DFT, revealing a double retro-S(N)2 pathway as the reasonable two-step mechanism.

Summary: Two novel ternary complexes, Cu(C10H8N2)(2)(C7H5O4)center dot 3H(2)O (complex 1) and [Pb(C10H8N2)(C7H5O4)(2)]center dot H2O (complex 2), were designed to enhance the catalytic performance of copper/lead 2,4-dihydroxybenzoate salt by introducing carbon framework ligand. The molecular structures of the complexes were determined by single crystal X-ray diffraction analysis. The thermal analysis results showed that complex 1 exhibited better thermal stability and remarkable catalytic activity on RDX compared to complex 2, changing the thermal decomposition of RDX from melting decomposition to solid phase decomposition.

Summary: A sustainable and cost-effective method for the preparation of dialdehyde nanocellulose (DANC) was developed through LiBr·3H2O (LBTH) non-dissolving pretreatment, which shortened the oxidation time and reduced the oxidant consumption. LBTH transformed the cellulose Iβ structure into an amorphous structure, reducing crystallinity and increasing aldehyde group content of DANC. The fabricated DANC exhibited strong antibacterial activity. LBTH could be recovered and reused, maintaining its effectiveness. This study provides a sustainable and clean approach for the preparation of DANC and promotes the application of cellulose nanomaterials.

Summary: In this study, a tunicate cellulose film with tunable haze levels was prepared by mixing tunicate microfibrillated cellulose (MFC) and tunicate cellulose nanofibrils (CNF). The film was used to modify the substrate of organic solar cells (OSC) to improve its light utilization efficiency. The dosage of MFC was found to be an important factor in adjusting the haze and light transmittance of the cellulose film. The optimized film showed excellent mechanical properties, high thermal stability, and when applied as an additional layer to the OSC substrate, resulted in a notable improvement of power conversion efficiency.

Summary: The interactions between three deep eutectic solvents (DES) and cellulose-hemicellulose and cellulose-lignin hybrid systems were studied using a simulated computational approach. DES pretreatment can disrupt the original hydrogen bonding network structure among the lignocellulosic components and reconstruct the new DES-lignocellulosic hydrogen bonding network structure. ChCl-U exhibited the strongest effect on the hybrid systems, removing 78.3% of the hydrogen bonds between cellulose-4-O-methyl Gluconic acid xylan (cellulose-Gxyl) and 68.4% of the hydrogen bonds between cellulose-Veratrylglycerol-b-guaiacyl ether (cellulose-VG), respectively. The addition of appropriate water (DES:H2O = 1:5) and DES formed a new DES-water hydrogen bonding network structure that facilitated the interaction with lignocellulose.

Summary: This study predicts the pretreatment efficiency of lignocellulosic biomass using ternary deep eutectic solvents (DES) containing Lewis acids through machine learning. Different statistical methods were used to analyze the correlation between 77 variables and the mechanism of lignin depolymerization. The results show that temperature, polarity related parameters of HBD, and acidity of Lewis acids significantly contribute to the degree of lignin depolymerization. The XGBoost model performs the best among all the machine learning models.

Summary: This study assessed the life cycle of bioethanol processes using choline chloride/urea (DES-U), choline chloride/lactic acid (DES-LA) and sodium hydroxide (NaOH) pretreatment. The net energy values for DES-U and DES-LA were negative, -4,107,023 MJ and -643,449 MJ respectively, indicating no positive energy benefits. High solid loading pretreatment directly reduced total net energy input. The renewability of DES-U and DES-LA was much lower than NaOH, while lignin-rich residue supply improved renewability. GHG emissions for NaOH, DES-U, and DES-LA were assessed at 10,278.8 kg CO2 eq., 12,801.8 kg CO2 eq., and 8,528.3 kg CO2 eq. respectively.
