Surimi-based products with high nutritional content are gaining popularity. Improving surimi gel properties is crucial for future processing and product quality. In this study, phosphorylated cellulose nanofibers (PCNFs) were used as a textural enhancer. Firstly, PCNFs are special fibers with active phosphate groups and high surface hydrophilicity, making them ideal as surimi gel additives. Furthermore, the creative use of PCNFs at a concentration of 0.15 wt% (0.15 g/100 g surimi) greatly improves the surimi gels' microstructure, including hardness by 89.57%, gumminess by 162.31%, and chewiness by 216.63%, and water holding capacity due to a synergistic effect between nanofibers and myosin. A model was created to illustrate the interaction between PCNFs and myosin in the surimi matrix. The model provides insights into the role of cellulose-based additives in food gels, aiming to develop innovative surimi products and provide guidance for creating high-quality cellulose-additive foods and understanding their functions in meat gel systems.

Molecular separations that purify and recovery waste solvents are essential to sustainable chemical industries. Solvent-resistant nanoporous cellulose membranes (CMs) hold great promise in organic separations, yet their pore engineering is hindered by extensive hydrogen bonding among hydroxyl groups of cellulose chains, thus restricting structural regulation for precise separations. Herein, we reported coordination-reconstructed cellulose membranes (CRCMs) by partially replacing hydrogen bonds with metal-organic coordination. Immersing CMs in alkaline cupric solution disrupts the hydrogen bonds among hydroxyl groups and establish hydroxyl-Cu 2+ linkages in cellulose networks. Altering Cu 2+ content in CRCMs enables precise tuning of pore size, generating superior permselectivity over current cellulose-based membranes. Cu 2+ coordination also enhances intrachain binding, which elevates the mechanical strength with nearly ten-fold increased swelling resistance of CRCMs, therefore harvesting pressure resistance up to 20 bar in ethanol. The optimized CRCM maintains stable permselectivity for over 2800 min and achieves solute rejection up to 99.9 % for multicomponent organic mixtures, demonstrating superior durability and adaptability for complicated organics separations. Our coordination-driven reconstruction approach may open new avenues for engineering biomass-based molecular-separation membranes.

Sodium carboxymethyl cellulose (CMC-Na) always serves as a thickening agent and secondary stabilizer in emulsions. In this paper, a boronate-modified CMC-Na (CMC-B) and its derivative were synthesized. Compared with CMC-Na, CMC-B could effectively stabilize O/W Pickering emulsions alone in alkaline environments. Furthermore, the emulsification performance of CMC-B was significantly enhanced by incorporating polyhydroxy macromolecules such as tannic acid (TA) through the formation of boronate-polyol groups. High-internal-phase O/W Pickering emulsions (HIPEs, V oil > 80 %) were achieved by the composite of CMC-B and TA (0.1 wt%, CMC-B-TA) at pH 8.0–11.0. The dynamic boronate-polyol linkages strengthened the cellulose network in the emulsions. This effect was applicable to various oil phases, as well as composites of CMC-B with other polyhydroxy compounds (e.g., polysaccharides and polyphenols). The salt tolerance and antioxidative capacity were also enhanced in the emulsions stabilized by CMC-B-TA. In contrast to the complex procedures required for the preparation of cellulose nanocrystals or nanofibers, this strategy employed a straightforward method to modify commercially available CMC-Na with boronate groups, yielding multifunctional emulsions that demonstrated both alkali resistance and antioxidant properties.

Supercapacitors have emerged as a significant technology for energy transmission, offering an alternative to traditional energy storage devices with the ability to provide a high power supply and life. However, their application and development have been hindered by tension between flexibility, self-support, and high energy density. In this study, cellulose was utilized as the primary raw material with graphene oxide (GO) employed as the filler. Through careful regulation of morphological control using radial freeze casting, the electrode exhibited both longitudinally and radially vertical-channeled porosity structure, resulting in a remarkable areal capacitance of 463 mF cm–2 at a current density of 1 A cm–2. Additionally, the constructed all-solid-state symmetric supercapacitor exhibited a high energy density of 49.7 μWh cm–2 at a power density of 500 μW cm–2. This research paves the way for more flexible and lightweight supercapacitors with the potential for long-term performance in energy storage applications.

Developing high-performance bio-based fibres is highly desirable for improving the sustainability of materials. Cellulose is one of the most abundant bio-derived feedstocks to fabricate such materials. However, the fabrication of high-strength macro cellulose fibres is challenging due to the difficulty in obtaining ordered packing of cellulose molecular chains and nanocrystals in the macro-fibres. Here we develop a draw spinning/de-acetylation method to prepare cellulose fibres with highly ordered molecular packing that incorporates high strength in the obtained fibres. Specifically, a fibre draw spun from well-dispersed cellulose triacetate solution was de-acetylated to generate cellulose fibres, which were then twisted to spirally align the molecular chains. The resulting fibres exhibited mechanical strength of 3.08 GPa and toughness of 215.1 MJ m − 3 , much higher than existing fibre materials. This work paves the way to obtaining high-performance bio-based fibres.

Ultrathin devices represent a significant advancement in materials science and technology, playing a crucial role in wearable electronics, smart healthcare, and human-computer interaction. However, achieving mechanical durability, interface stability, and performance trade-offs remains challenging. Herein, the study reports a scalable layer-by-layer exfoliation strategy for the rapid and patterned fabrication of ultrathin cellulose ionogel devices, employing a solvent-induced assembly of cellulose molecules and active substances. The resulting freestanding devices, with a thickness of 12.46 µm—approximately one-ninth the thickness of human hair, exhibited desirable mechanical tensile strength (6.5 MPa), high pressure sensitivity (75.82 kPa −1 ), low impedance characteristics (5.83 Ω at 1 kHz), and outstanding interfacial stability, as evidenced by the ability to endure 500 cycles of tape stripping. Furthermore, due to effective self-healing and controllable induced peeling characteristics, the study is able to conduct the patterned fabrication of various ultrathin devices without the limitation of active materials. This peeling strategy based on sustainable resources offers a valuable solution for designing and optimizing ultrathin electronic devices without requiring substantial time or cumbersome processing.

Hydroxyapatite (HAp)/bacterial cellulose (BC) nanocomposites were prepared by an optimal biomimetic mineralization synthesis approach for bone tissue engineering application. BC with ultrafine three dimensional network was negatively charged by the adsorption of polyvinylpyrrolidone (PVP) to initiate the nucleation of HAp. The HAp was grown in vitro along the nanofiber network of BC via dynamic simulated body fluid (SBF) treatment. It was found that rod-like HAp particles in the nano-scale (100–200 nm) homogeneously deposited on the surface of PVP-BC. ATR-Fourier Transform Infrared Spectroscopy (ATR-FTIR) results showed that carbonate-containing HAp crystals resembling natural bones were formed by biomimetic mineralization method. Moreover, the amount of HAp observed increased with increasing mineralization time. And the Ca/P overall ratio ranged from 1.37 to 1.59. The results from Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) indicated that PVP treatment enhanced the apatite nucleation ability of BC with higher HAp deposit amount.

Cellulose fibers have been successfully isolated from medium density fiberboards (MDFs) by sodium chlorite oxidation-potassium hydroxide (NaClO 2 -KOH) leaching process, at 37.6% yield, comparable to the 39.3% and 37.3% cellulose fibers from eucalyptus and eucalyptus with 12% cured urea-formaldehyde (UF) resin, respectively. At the same sulfuric acid hydrolysis conditions (65% H 2 SO 4 , 60 °C and 30 min), MDF cellulose nanocrystals (CNCs) were produced at 27.5% yield, similar to 27.4% of CNC yield from eucalyptus with UF resin, but less than 31.2% yield from eucalyptus. MDF CNCs were slightly thicker in lateral dimension (16.8 ± 8.6 nm), less crystalline (59% CrI), and surface esterificated (0.045 mmol/g sulfate/CNC) than eucalyptus CNCs (11.6 ± 3.9 nm, 75% CrI, 0.060 mmol/g) and CNCs from eucalyptus with UF resin (14.9 ± 9.1 nm, 65% CrI, 0.046 mmol/g). All CNCs were free of UF resin and thermal stable. The residual resin in cellulose pulps hydrolyzed completely during the sulfuric acid treatment and contributed to the unique properties of CNCs. Therefore, CNCs derived from MDF are comparable to CNC from wood and promising for expanded applications.

Chiral transfer from cellulose nanocrystals (CNCs) chiral nematic liquid crystal to polyaniline (PANI) is successfully achieved through co-assembly method for the first time, affording the PANI film based on CNCs optical activity. Meanwhile, the CNCs/PANI composite film displays notable Cotton effect ascribed to the polaron band transitions of PANI in circular dichroism (CD) spectrum. Hydrogen bond and electrostatic attraction favor the combination of two molecular chains in the mixed aqueous suspension and will lead to the chiral assembly of the PANI in the host chiral nematic film. However, the CD signal disappears when cholesteric phase collapse by acid protonation, and which demonstrates the chiral nematic ordering of the CNCs is essential to the chiral transfer. With the assistance of CNCs, PANI chains form a helically stacked structure. Thus, the optical activity of PANI originates from its long range organization.

The twisted structure of cellulose nanocrystals (CNCs) endows them with the ability to form a cholesteric phase and, consequently, a photonic crystal film through evaporation-induced self-assembly (EISA). However, the physically force-dominated CNCs-based chiral photonic film (CCPF) exhibits obvious defects such as brittleness and water solubility. Here, we combine EISA with covalent crosslinking to prepare CCPFs via the Schiff base reaction between dialdehyde cellulose nanocrystals (ACNCs) and polyethyleneimine (PEI). Compared with the ACNCs film, ACNCs-PEI CCPFs demonstrate a significant increase in tensile strength (∼101 MPa) and elongation at break (1.31 %). After immersion in acidic, neutral, and alkaline solutions for 24 h, the as-prepared CCPFs can still retain their original shape. The CCPFs also exhibit left-handed chirality and excellent UV-blocking properties. Surprisingly, the abundant sub-fluorescent groups and crosslink-enhanced emission effect give CCPFs exceptional photoluminescence behavior. Overall, this work offers a method to produce high-tensile-strength CCPFs by combining covalent cross-linking with EISA, which can be extended to other hybrid CCPFs containing polyamine compounds.

Sponges with large protein adsorption capacity are highly desired in various fields such as biosensors, biofuel cells, biocatalysis, and protein chromatography. However, the use of environmentally friendly materials and mass production still face enormous challenges. Herein, a novel and facile method to fabricate an environmentally friendly monolithic cellulose/chitosan composite sponge (CECSS) with remarkable performance is designed using the mature viscose process. The obtained highly efficient adsorption sponge exhibits a hierarchical porous structure with open-pore structures with a diameter range of 200–1000 μm and small micro/nanocellular structures (0.5–2 μm), which endow it with remarkable porosity (62.95%) and water adsorption capacity (1409%). Based on the abovementioned unique porous structure and reactive groups of chitosan, the CECSS exhibits a high bovine serum albumin adsorption capacity of 200.56 mg/g at pH 5.5 for 10 h. In addition, the adsorption of the CECSS can be well described by the pseudo-second-order kinetic model and the Langmuir isotherm model. This work provides a new sponge-forming process for the fields of protein adsorption, which may achieve the production of natural protein adsorbents at the industrial level.

In an attempt to obtain bacterial cellulose (BC) with controllable pores, Ca-alginate particles were introduced into BC fermentation medium. Ca-alginate particles with different diameters were prepared through electrostatic spinning and pulverization. After removing the particles, a continuous and homogeneous network of pores with diameters around 5 μm, 20 μm, and 400 μm were presented inside BC hydrogel. Compared to native BC, the crystallinity, the surface area and water holding capacity (WHC) were all increased when the pore sizes around 5 μm, 20 μm. However, the porous BC with diameters around 400 μm showed poor performance in WHC and mechanical strength. This novel approach described in this paper introduced a new approach for creating controllable porous BC with user-defined control over the physical dimensions of the network, and slightly changed its structure.
