In this study, an ultra-light porous aerogel was synthesized utilizing Blueberry anthocyanin (BA) and cellulose nanofibrils (CNF), and the freshness of shrimp was assessed through the colorimetric response of the aerogel. Through modification by Vinyltrimethoxysilane (VTMO), the aerogel's surface properties were altered from hydrophilic to hydrophobic, thereby enhancing its practicality in wet environments. By adjusting the concentrations and ratios of BA and CNF, key physical characteristics such as density, porosity, and specific surface area of the aerogel can be precisely controlled. These properties influence the aerogel's capacity to adsorb gases, thereby affecting its color change reversibility, sensitivity, and stability. Among all aerogels with varying proportions of BA/CNF (1:2, 1:3 and 1:4), the one prepared with a ratio of 1:3 (BA/CNF 1:3 aerogel) exhibited a high porosity and specific surface area, demonstrating exceptional sensitivity to alkaline gases and remarkable stability under light conditions. The detection limits of total volatile basic nitrogen (TVB-N) in BA/CNF 1:3 aerogel for detecting shrimp meat spoilage were 20.02 mg/100 g at 4 °C and 29.87 mg/100 g at 25 °C respectively. This kind of composite aerogel could be used for sensitive and visual monitoring of shrimp freshness, thereby reducing food waste and offering a novel approach to intelligent development within the food packaging industry.

Cellulose sponges are widely used in the fields of thermal insulation, adsorption and catalysis owing to their low density, high porosity and low thermal conductivity. However, they suffer from complex preparation process and poor mechanical property. In response to this, an ambient pressure drying route was investigated to prepare the mineral-reinforced cellulose sponges using bagasse and minerals as main raw materials. Thanks to the cross-linking reactions among cellulose, mineral, glutaraldehyde and chitosan, a more stable three-dimensional network structure was formed, enhancing the mechanical property of sponge. The kaolin-reinforced cellulose sponges exhibited a bulk density of 70.10 mg/cm 3 , a porosity of 99.20 %, a compressive strength of 231.20 kPa at 50 % strain, and a thermal conductivity of 43.50 mW/(m·K). The present cellulose sponge prepared by ambient pressure drying, with its easy operation and low cost, low thermal conductivity and acceptable mechanical strength, can be potentially be used as thermal insulation materials in buildings.

Ionic conductive hydrogels (ICHs) are promising substitutes for rigid metal conductors in flexible sensors. However, integrating high strength, self-adhesion, conductivity, and anti-freezing properties remains a critical issue. Herein, a facile strategy for fabricating a mechanically robust hydrogel with remarkable conductivity and consistent self-adhesion by combining carboxymethylcellulose (CMC) and acryloyloxyethyltrimethyl ammonium chloride (ATAC), 2-acrylamide-2-methylpropanesulfonic acid (AMPS) is reported. The resulting hydrogels demonstrated high ionic conductivity (8.2 S/m), excellent mechanical properties (tensile strength: 0.5 MPa; tensile strain: >1701 %), and strong self-adhesion (up to 10.39 kPa) owing to ionic interactions and hydrogen bonding. With a gauge factor of 2.15, the hydrogels exhibited sensitive electromechanical responses, enabling reliable detection of both large and subtle human motions. When assembled into a flexible strain sensor, it exhibited high sensitivity, facilitating the detection of both significant deformations and subtle human movements. This work provides valuable insights into the rational design of cellulose-based ICHs for advanced bioelectronic applications.

Strong and tailored circularly polarized luminescence (CPL) from fluorophores embedded in chiral matrices has gained significant interest in photonic technologies. However, fluorescence quenching due to molecule aggregation occurs in the solid state at high fluorophore loading. Here, we present a simple polymer induced fluorescence enhancement strategy to fabricate robust luminescent films composed of cellulose nanocrystal (CNC) and rhodamine 6G (Rh6G). The type, molecule weight, and concentration of the polymer are found to play critical roles in modulating film fluorescence. The results demonstrate that polymer effectively migrates fluorescence quenching by shielding interactions between Rh6G molecules and CNC-Rh6G, leading to a remarkable enhancement of up to 47 times. The left-handed chiral nematic structure of CNCs can transform the Rh6G emission into controllable left or right-handed CPL. By adjusting the polyethylene glycol concentration and photonic band gap of composite films, CPL with tunable handedness, intensity, and wavelength are achieved, yielding a dissymmetric factor ranging from −0.35 to 0.14. This polymer induced fluorescence enhancement and tunable CPL highlight the potential of CNC-based luminescent films for advanced functional materials.

The urgent need to prolong the shelf life of fruits and vegetables in a cost-effective and environmentally friendly manner has become paramount in addressing socio-economic challenges and minimizing food waste. In this study, a bio-composite coating was developed for fruit and vegetable preservation, utilizing egg protein as the bio-based film-forming component, egg yolk as the hydrophobic element, cellulose nanofibers for reinforcement, and Nisin as an antimicrobial agent. The preservation efficacy of this coating was examined using bananas and cherry tomatoes , and its mechanism was analyzed. The findings revealed that the coating successfully formed a thin layer on the surface of the fruits, ranging in thickness from nanometers to micrometers. This innovative coating prolonged the shelf life of the fruits by over 6 days under 20 °C, preserving their appearance, hardness, and nutrient content during storage. By inhibiting gas exchange and warding off microbial infestation, the coating effectively slowed the ripening and decay processes. Additionally, its edibility and washability alleviated food safety concerns without compromising the fruit's natural taste. This research offers an innovative solution to the global food waste problem, serving as an environmentally responsible and highly scalable method for maintaining freshness.

CO 2 capture and release are critical for enhancing photosynthetic efficiency of plants and biomass accumulation. However, achieving efficient capture and directional transport of CO 2 to plants near the source of carbon emissions to boost photosynthetic efficiency are mains an important technical challenge. In this study, we introduce an innovative strategy for fabricating a cellulose-based CO 2 -capture foam-like porous material-DGP, which can significantly enhance the photosynthetic efficiency of tobacco plants. By chemically crosslinking superbranched amino polymers on a lignocellulose substrate, DGP not only exhibits excellent CO 2 capture capacity of 8.01 mmol g −1 at room temperature, but also achieves an effective slow release of CO 2 with a release rate of up to 51 % and a duration of up to 10 h without additional energy input. This characteristic allows DGP to simulate the CO 2 concentration mechanism of plants in nature, thereby increasing the net photosynthetic efficiency of tobacco by 70 % and the intercellular CO 2 concentration by 52 %, which significantly promotes the accumulation of biomass. The utilization of this material has broad application prospects for enhancing the carbon sink capacity of the ecosystem, mitigating the greenhouse effect and improving crop yield.

5-Hydroxymethylfurfural (HMF) is an important platform compound that can be used to synthesize drugs, fine chemicals, fuels, and biodegradable plastics. Synthesis of HMF from cellulose is a key step in the production of high-value-added chemicals and fuels from renewable cellulosic biomass. Herein, a cheap way to produce HMF from cellulose was found in this study. Combination of inexpensive metal salts and inorganic acids shows exciting catalytic efficiency in tetrahydrofuran (THF)/H 2 O system. In this article, the effects of key factors such as water/organic solvent ratio, metal salt type, and concentration on the synthesis of HMF from cellulose were investigated. A maximum HMF yield of 46.5% was obtained with high substrate loading (50 g/L) when H 2 SO 4 and Al 2 (SO 4 ) 3 was used as mixed acid catalysts. Reaction kinetics experiments revealed that combination of H 2 SO 4 and Al 2 (SO 4 ) 3 could effectively reduce the activation energy of cellulose hydrolysis, glucose isomerization, and fructose dehydration compared to the single H 2 SO 4 and single Al 2 (SO 4 ) 3 system. Fortunately, the purity of HMF after separation and purification was up to 98.3%, and both the solvent and the extractant can be recycled. A promising strategy is provided for HMF production from cellulose over simple catalysts.

The widespread application of nano-finishing agents in cotton functionalization has been hindered by concerns over their potential toxicity and inadequate durability. Herein, we demonstrate a facile strategy for the in-situ synthesis of manganese oxide (MnO₂) on cotton textiles via alternating assembly of potassium permanganate (KMnO 4 ), manganese chloride (MnCl 2 ) and 2,3-epoxypropyltrimethylammonium chloride (EPTAC). In this process, EPTAC was grafted onto cotton fibers, subsequently enabling the rapid adsorption and reduction of KMnO 4 to MnO 2 nanoparticles within 5 min, as well as minimizing fiber damage. Concurrently, EPTAC could be anchored between the negatively charged MnO 2 catalysts and cellulose structures through intermolecular coordination bonds, etherification grafting, and electronic interactions, thereby enhancing nanoparticle adhesion to the fibers and ensuring exceptional durability during repeated washing cycles. The Ag doping strategy in MnO 2 structure generated additional vacancies and significantly improved electron transfer efficiency, endowing the resulting textiles with remarkable antibacterial properties, including over 99 % inactivation in 20 min of irradiation. The treated textiles also demonstrated outstanding formaldehyde (HCHO) removal efficiency, achieving 72 % degradation within 30 min, accompanied by superior UV-blocking performance. The proposed deposition strategy of MnO 2 nanoparticles on cotton textiles provides an alternative for fabricating multifunctional decorative textiles, offering potential for indoor pollutant removals.

Development of a high-strength bio-based adhesive using simple, environment-friendly method is of great significance, as an alternative to petroleum-based adhesives. In this paper, Cellulose colloidal adhesives (CCA) with high stability and good reactivity were prepared by selective activation of microcrystalline cellulose (MCC) using sodium periodate under acidic conditions, with colloidal sizes ranging from nanometers to micrometers. CCA was applied to different types of veneer (poplar/beech/pine) to prepare 3-ply plywood. Compared to conventional activated cellulose adhesives, the CCA plywood showed excellent water resistance, dry/wet tensile shear strength of 3.7 MPa/1.6 MPa, met the requirements of Chinese national standards (GB/T 9846–2015). The excellent water resistance of CCA plywood was attributed to several factors. The colloidal particles filled the cell lumina of the wood, creating a mechanical interlocking effect. Additionally, CCA self-crosslinked to form stable intermolecular forces, the formation of cellulose nanocrystals by selective activation has an enhancing effect for CCA, while covalent and non-covalent bonds were established between CCA and the wood. Meanwhile, CCA has been shown to be universally applicable to cellulose extracted from various types of wood. This study realized the virtuous cycle of “from wood to wood”.

Utilizing carbonic anhydrase (CA) to catalyze CO 2 hydration offers a sustainable and potent approach for carbon capture and utilization. To enhance CA's reusability and stability for successful industrial applications, enzyme immobilization is essential. In this study, delignified bamboo cellulose served as a renewable porous scaffold for immobilizing CA through oxidation-induced cellulose aldehydation followed by Schiff base linkage. The catalytic performance of the resulting immobilized CA was evaluated using both p -NPA hydrolysis and CO 2 hydration models. Compared to free CA, immobilization onto the bamboo scaffold increased CA's optimal temperature and pH to approximately 45 °C and 9.0, respectively. Post-immobilization, CA activity demonstrated effective retention (>60 %), with larger scaffold sizes (i.e., 8 mm diameter and 5 mm height) positively impacting this aspect, even surpassing the activity of free CA. Furthermore, immobilized CA exhibited sustained reusability and high stability under thermal treatment and pH fluctuation, retaining >80 % activity even after 5 catalytic cycles. When introduced to microalgae culture, the immobilized CA improved biomass production by ∼16 %, accompanied by enhanced synthesis of essential biomolecules in microalgae. Collectively, the facile and green construction of immobilized CA onto bamboo cellulose block demonstrates great potential for the development of various CA-catalyzed CO 2 conversion and utilization technologies.

High-polymer biomass is reactively inert due to its large molecular weight and stable structure, and the depolymerization is an effective strategy to enhance its utilization. Herein, a typical dielectric barrier discharge (DBD) system was established to realize efficient depolymerization of cotton cellulose, where the degree of polymerization declined from 2329 to 430, decreased by 81.5%. H 2 O 2 , O 3 , •OH, O 2 • − and 1 O 2 dominated the depolymerization process by attacking the β -(1,4) glycosidic bonds and hydrogen bonds in cellulose molecules. In addition, the treated cotton cellulose displayed smaller blocks, rougher surface and poor thermal stability, and the crystallinity of cellulose decreased by 15.4% after DBD pretreatment. Interestingly, there were no obvious chemical changes in the main structure of cellulose, only with slight release of substances such as monosaccharides and alcohols. Therefore, these indicated that DBD process achieved the reduction of polymerization and crystallinity while ensuring that the original cellulose structure was not damaged, and was an efficient and alternative pretreatment method for high-polymer biomass.

The physical dissolution of cellulose in aqueous solutions of tetramethyl ammonium hydroxide, triethylmethyl ammonium hydroxide, tetraethyl ammonium hydroxide, benzyltrimethyl ammonium hydroxide, benzyltriethyl ammonium hydroxide, NaOH and LiOH via freezing–thawing was investigated. Increasing the hydrophobicity of the cation greatly improved its dissolution capacity, leading to significant enhancement of cellulose solubility and stability against chain aggregation and gelation. The hydrophobic cations accumulated at the cellulose interface and decreased the surface tension, favouring dispersion of the disintegrated cellulose due to its amphiphilicity; this was consistent with molecular dynamics simulations. On the other hand, the solubility of cellulose followed the Hofmeister series, and cations with greater kosmotropicity originating from their greater hydrophobicity exhibited stronger dissolution power; this observed interaction pattern may be useful for further exploration and designation of novel solvents of cellulose. These aqueous quaternary ammonium hydroxides can be readily recycled and reused, which presents great potential in the green chemistry field.
