Summary: A novel method for producing organophilic cellulose nanocrystals (CNC-ODA) from microcrystalline cellulose (MCC) was proposed. Surface modification of MCC was achieved through chemical oxidation, citric acid esterification, and amidation reactions. The resulting nanocrystals exhibited improved hydrophobicity and thermal stability compared to unmodified MCC.

Summary: This study aims to develop a green and efficient method for synthesizing antimicrobial amino-functionalized microcrystalline celluloses from cotton fibers. Microcrystalline cellulose was prepared by acid hydrolyzing of cellulose. Tosyl cellulose was synthesized by tosylation of cellulose in an eco-friendly medium using NaOH/urea and decyl glucoside surfactant with DSTs of 0.51. Three amino-functionalized cellulose derivatives were synthesized by nucleophilic substitution reaction of tosyl cellulose with 3-aminopropyltrimethoylsilane, ethylenediamine, and triethylenetetramine. The physicochemical properties of investigated celluloses were characterized by Fourier transform infrared spectroscopy, X-ray diffraction analysis, scanning electron microscopy, and thermogravimetric analysis-differential scanning calorimetry. Microcrystalline cellulose with high crystallinity index (81.90%) and crystalline size of 0.30 nm was isolated from cotton fibers. After the dissolution and chemical modification, the crystalline form of cellulose was transformed from cellulose I to amorphous cellulose II. The thermal degradation of aminated cellulose was around 260 degrees C. The amino cellulose exhibited high inhibition activity against S. aureus, P. aeruginosa, and E. coli with MIC values less than 5 mg mL(-1). The chemical modification of surface cellulose could deliver antimicrobial cellulosic materials with potential applications for air and water treatments or as ingredients in the food, cosmetic, and pharmaceutical industries.

Summary: Adsorption deacidification is a promising extraction technology for peony seed oil, overcoming issues in traditional processes. The optimal conditions for adsorption deacidification were determined as 3% adsorbent-alkali microcrystalline cellulose, a heating temperature of 50°C, and a holding time of 60 min. Compared to alkali refining and oil-hexane miscella deacidification, adsorption deacidification exhibited higher retention of tocopherols (92.66%), phytosterols (91.96%), and polyphenols (70.64%). Additionally, the extracted oil retained approximately 67.32% of total antioxidant activity and showed 1.35 times increased oil stability index.

Summary: A process combining two natural-based products was developed to obtain bio-based films. A cellulose/ESBO solution was prepared using a distillable and recyclable ionic liquid-based solvent. The resulting cellulose films exhibited flexible and solvent-free characteristics, with the presence of triglyceride structures and the absence of epoxide rings. The films showed adjustable flexibility and hydrophilicity properties due to the presence of ESBO, making them suitable for various applications.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
