1. {"_":"Carboxylation of lyocell fabrics using C-1 lytic polysaccharide monooxygenases (LPMO9A) for enhanced affinity to cationic dye.","i":["Dc"]}
PMID:日期:2026-06-30Regenerated cellulosic fibers, such as lyocell fibers, are fully biodegradable and of 100% bio-based origin. With properties like high dry tenacity, they are widely used in many high-quality fiber applications. Yet, targeted surface functionalization could improve their processing such as dyeing. Reactive dyes are the dominant class for dyeing cellulosic fibers because they exhibit high affinity and form covalent bonds with cellulose. By contrast, cationic dyes show poor affinity to unmodified cellulose and are therefore not inherently suitable for lyocell unless additional anionic binding sites are introduced. To address this, we have investigated enzymatic surface functionalization of lyocell fabrics to increase negative charges. The C1-acting lytic polysaccharide monooxygenase (LPMO) LPMO9A from was employed to functionalize lyocell fabrics to increase cationic dye uptake without substantial loss in fabric yield. The C1 oxidation of lyocell fiber was quantified through selective labeling and fluorescence analysis and directly correlated to cationic dye uptake. Remarkably, rhodamine-6G (R6G) dye uptake increased by up to 75% using less than 1% w/w LPMO9A loadings. Further analysis of fiber properties and yield demonstrated that LPMO9A treatment did not compromise fiber quality.

2. Evaluation of polyethyleneimine-functionalized cellulose for the capture of valeric acid, a model wound malodor compound.
PMID:日期:2026-04-17Short-chain fatty acids (SCFAs), such as valeric acid, are key contributors to malodor in chronic wounds, yet conventional sorbents fail to retain these volatile compounds effectively. To address this, polyethyleneimine-functionalized cellulose (PFC) was developed as a reactive sorbent for selective SCFA capture via ionic interactions between protonated surface amines and dissociated acid anions. PFC was synthesized via covalent immobilization of branched polyethyleneimine onto cotton cellulose using poly(ethylene glycol) diglycidyl ether. Successful functionalization was confirmed through elemental analysis, fluorescence microscopy, scanning electron microscopy, and hydrophilicity assessments. Absorption studies revealed that the valeric acid uptake correlated with the PEI content, peaking at 2.35% nitrogen incorporation. Kinetic experiments demonstrated rapid absorption within the first hour, reaching equilibrium by four hours, while absorption efficiency increased under neutral-alkaline conditions (pH 7-8) and elevated temperatures (33-37 °C). In vitro biocompatibility tests using L929 fibroblasts and XTT assays showed no cytotoxicity, underscoring PFC's suitability for biomedical applications. This work establishes PFC as a promising malodor-control strategy for chronic wound management, combining enhanced SCFA absorption, retention, and cytocompatibility.

3. Probing molecular interactions of cellulose fibers with isomeric deep eutectic solvents using NMR spectroscopy.
PMID:日期:2026-01-22Deep eutectic solvents (DESs) are promising media for cellulose fiber (CF) modifications, such as swelling, dissolution, functionalization, and disintegration, owing to their low toxicity, biodegradability, and versatility. These modifications are governed by CF-DES interactions, regulated by the chemical structures of DES constituents. Here, nuclear magnetic resonance (NMR) spectroscopy was used to investigate the molecular interactions and dynamics between CFs and two isomeric non-derivatizing DESs comprising triethylmethylammonium chloride (TEMACl) with imidazole (Imi), TEMACl-Imi, or TEMACl with pyrazole (Pyra), TEMACl-Pyra. The NMR approach encompassed variable-temperature H diffusion, -and- -relaxation, and C NMR experiments. Significant CF swelling occurred in TEMACl-Imi, highlighted by reduced Imi and almost unchanged TEMACl relaxation times. This indicated that Imi primarily accounted for the interaction with cellulose. Correspondingly, the diffusion coefficients () of both DES components reduced, probably because of the increased viscosity due to CF swelling, as well as restricted diffusion inside the swollen CFs. Further, the C NMR spectra displayed characteristic cellulose-backbone signals, indicating a swelling-induced increase in CF mobility. Conversely, TEMACl-Pyra exhibited significantly suppressed changes in H-relaxation times and , and no cellulose signal appeared in its C spectra. This indicated suppressed CF swelling and CF-DES interaction. The more significant CF swelling in TEMACl-Imi might stem from the formation of stronger hydrogen bonds by Imi with the hydroxyl groups in cellulose compared with those formed by Pyra. Overall, these findings highlight how the molecular configuration of DES facilitates cellulose interactions and the profound impact of these interactions on CF modification.

4. A comparative study of effects of microwave-assisted deep eutectic solvents pretreatment of rice straw on cellulose enrichment and enzymatic digestibility.
PMID:日期:2025-11-06Lignocellulosic biomass (LCB), such as agricultural residue rich in cellulose and hemicellulose, can serve as a feedstock for bioethanol production due to its environmental benefits. Deep eutectic solvents (DES) are low-cost and greener solvents for LCB pretreatment. The present study investigated the efficiency of two DES types for rice straw pretreatment under microwave conditions: choline chloride:glycerol (ChCl:Gly) and choline chloride:formic acid (ChCl:FA). DES pretreatment was performed under microwave conditions (100-140 °C and 5-15 min) at 10% solids loading and constant power 200W. After pretreatment, the samples were characterized, and enzymatic digestibility was investigated at 50 °C for 72 h using enzyme loading of 6 filter paper unit g cellulose and 10% solids loading. Untreated rice straw consists of cellulose (41.8%), hemicellulose (24.9%), lignin (17.0%) and ash (15.0%). The cellulose content increased to 59.8% and 59.2% after ChCl:Gly and ChCl:FA pretreatment, respectively, while hemicellulose decreased to 15.6% and 10.1% after ChCl:Gly and ChCl:FA pretreatment, respectively. Lignin content decreased to 8.2% after ChCl:Gly pretreatment compared to 9.6% after ChCl:FA pretreatment. Ash content (20.4%) obtained after ChCl:FA pretreatment was higher than 14.0% obtained after ChCl:Gly pretreatment. The cellulosic and hemicellulose fractions from ChCl:Gly pretreatment were effectively hydrolyzed with glucose and xylose yield of 86.0% and 68.4%, respectively, compared to glucose and xylose yield of 58.2% and 62.8%, after ChCl:FA pretreatment. ChCl:Gly pretreatment enriched cellulosic content and preserved hemicellulose fraction, achieving a higher yield of fermentable sugars than ChCl:FA pretreatment; hence, it can potentially support a biorefinery.

5. Enhanced production of bacterial cellulose with a mesh dispenser vessel-based bioreactor.
PMID:日期:2025-01-29Bacterial cellulose (BC) has gained significant interest for various applications due to its useful properties which include chemical stability and strong physical properties as well as its biocompatibility. However, conventional fabrication methods are limited by a lack of control over the form, particularly depth and thickness, restricting BC applications to 2D planar shapes. The production of BC is constrained by the formation of a pellicle at the liquid-air interface. To overcome this constraint and enable continuous pellicle formation, a method was established to combine intermittent batch feeding with a supportive mesh scaffold. Intermittent feeding supplies nutrients to the pellicle, promoting sustained formation at the liquid-air interface, while the supporting mesh anchors the initial pellicle to prevent submersion. This approach facilitates the continuous growth of BC pellicle at a controlled rate. Moreover, the method described here results in a single BC pellicle with enhanced thickness, weight (both wet and dry states), water-holding capacity and mechanical strength. Continuous growth is achievable with ongoing nutrient supply, allowing for precise control over the final pellicle thickness. This culturing method is scalable and has been tested for volumes ranging from 250 mL to 10 L, and significantly increases glucose-to-cellulose conversion (3.4-fold) and water utilization efficiency (2.4-fold).

6. Optical assessment of lignin-containing nanocellulose films under extended sunlight exposure.
PMID:日期:2025-01-15This study investigates the stability and UV-blocking properties of cellulose nanofibril (CNF) and TEMPO-oxidized cellulose nanofibril (TOCNF) films, with and without lignin, under 1000 h of artificial sunlight. The literature to date provides no quantitative analysis of such films' stability, however such insight is critical for optoelectronic applications for instance solar cells. This contribution examines the films from practical perspectives, considering aging with respect to their optical performance and retention of UV protective qualities. Films containing residual lignin (LignoCNF and LignoTOCNF), and lignin nanoparticles (CNF-LNP and TOCNF-LNP) demonstrated remarkable UV-blocking stability; even after the aging transmittance of LignoCNF and CNF-LNP films remained lower than 1% below 390 nm. Most lignin-containing films exhibited increased transmittance between 400 and 600 nm after aging, except for LignoTOCNF, which showed a decrease in transmittance that was comparable to that displayed by non-lignin films. Nevertheless, long-term light exposure induced a decrease in their mechanical properties. Tensile tests revealed increased brittleness in CNF and LignoCNF, while LNP-containing films showed reduced strain at the break. The observed changes were linked to the potential oxidation of COO- groups and structural modifications in both cellulose and lignin. Overall, the incorporation of lignin into nanocellulose films enhances their durability, UV protection, and mechanical stability, making them promising candidates for sustainable optoelectronic applications.

7. {"_":"Efficient extraction of carboxylated nanocellulose from ionoSolv pulps with alkaline HO assisted oxidation.","sub":["2","2"]}
PMID:日期:2024-12-11We report a simple procedure to produce carboxylated cellulose nanocrystals (CNCs) from grassy biomass () using a two-step approach consisting of biomass fractionation with a protic ionic liquid followed by oxidation of the resulting cellulose-rich pulps with HO. The impact of the fractionation severity on the composition, structure, size, thermal stability, crystallinity, and degree of polymerization of the CNCs was evaluated. It was found that fractionation severity had a large impact on the pulp purity and its reactivity during the oxidation stage. Nevertheless, the impact on the properties of the final CNCs was small. CNCs were recovered as suspensions of negatively charged, electrostatically stable, needle-like CNCs with a lower degree of crystallinity (58-61%) compared to the precursor pulps (65-69%). The presence of carboxyl groups on the surface of the CNCs facilitated the stability of the suspensions but also caused a slight decrease in the thermal stability of the CNCs. A milder oxidation process followed by ultrasonication allowed us to maximize the production of CNCs while better preserving the degree of crystallinity of the cellulose (63%).

8. The tensile behaviour of paper under high loading rates.
PMID:日期:2024-12-03This work deals with the strain-rate dependent characterization of paper under uniaxial tension at high strain-rates. Experiments were performed involving a Split Hopkinson bar for high strain-rate testing, comparing the results with conventional quasi-static tests. Tests were conducted in a strain-rate range between 0.0083 and 212 s, which is equivalent to testing velocities between 0.0003 and roughly 13.6 m/s. For the first time the change in tensile behaviour of paper is comprehensively characterized and modelled, using the Cowper-Symonds model for strain-rate hardening. The experimental tests showed that the tensile strength as well as the initial stiffness were gradually increasing with increasing strain-rate. The increase in tensile strength between the lowest and the highest strain-rate was 58% on average whereas the mean increase in stiffness between these two strain-rates was almost 115%. Regarding the fracture strain, it was observed that it significantly decreases with increasing strain-rate. While the average fracture strain of the quasi-static tests was at roughly 6% it was close to 3% for the dynamic tests. In case of the Split Hopkinson bar tests, high-speed videos of the samples were made to determine their elongation via target tracking and digital image correlation (DIC). We found that strain localization, which is a highly relevant mechanism for quasi-static tensile failure, is likely related to short term plastic creep of the material as strain localization nearly entirely disappears at high loading rates of paper.

9. Fractionation of wood due to industrial chipping: effects and potential for Kraft pulping of European spruce.
PMID:日期:2024-03-03The research conducted on kraft cooking of for different chip sizes is often not representative for the industrial process since the chip size fractions were made of high-quality wood without impurities. We evaluated the effects and the potential of cooking non ideal spruce chip fractions after industrial chipping and screening. The chips were classified according to SCAN 40:01, and the respective fractions were cooked under the identical conditions to mimic the effect of a joint cooking in the industrial digester. For the undersized chips we found higher bark content, a lower screened yield, a higher Kappa number, lower fiber length and lower tensile strength. For the oversized chips, the fiber length and tensile index were also considerably lower. A lower wood quality due to high knot content in the larger fractions was found to be the reason for that. Based on the data obtained from the experiments and literature, different process options for increased yield and reduced chemical consumption are discussed, e.g., separate cooking of different chip fractions. Improved chip screening seems to be the process improvement with lowest costs and highest impact.

10. Lignin nanoparticles as co-stabilizers and modifiers of nanocellulose-based Pickering emulsions and foams.
PMID:日期:2023-07-29Nanocellulose is very hydrophilic, preventing interactions with the oil phase in Pickering emulsions. This limitation is herein addressed by incorporating lignin nanoparticles (LNPs) as co-stabilizers of nanocellulose-based Pickering emulsions. LNP addition decreases the oil droplet size and slows creaming at pH 5 and 8 and with increasing LNP content. Emulsification at pH 3 and LNP cationization lead to droplet flocculation and rapid creaming. LNP application for emulsification, prior or simultaneously with nanocellulose, favors stability given the improved interactions with the oil phase. The Pickering emulsions can be freeze-dried, enabling the recovery of a solid macroporous foam that can act as adsorbent for pharmaceutical pollutants. Overall, the properties of nanocellulose-based Pickering emulsions and foams can be tailored by LNP addition. This strategy offers a unique, green approach to stabilize biphasic systems using bio-based nanomaterials without tedious and costly modification procedures.
