The capture of SO 2 by recyclable absorbents has drawn much attention all over the world. In this work, it was found that aqueous calcium lactate (CaL 2 ) solution can be used as a recyclable absorbent for the capture of SO 2 . The solution shows high SO 2 absorption capacities up to 24.8 g SO 2 /kg absorbent at 40 °C. The effects of temperature, excessive lactic acid and CaL 2 concentration on the absorption of SO 2 , the desorption of SO 2 , and the reuse of aqueous CaL 2 solution were systemically studied. Furthermore, the difference between CaL 2 method and traditional calcium method was discussed. Compared with traditional calcium method, there are some advantages, such as regeneration of absorbent, recovery of SO 2 and reduction of CaSO 4 . This work suggests that aqueous CaL 2 solution, which can be obtained at quite low cost, is a promising recyclable absorbent in the process of desulfurization of flue gas.

Chitin is a natural biomass material with wide sources and high application potential, but the solvents for dissolving chitin are very limited. In this work, ternary alkaline deep eutectic solvents (DESs) containing amino acids, urea, and 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) were prepared, which can successfully achieve the dissolution of chitin and can be recycled. By adjusting the type of amino acids and the amount of DBU, the maximum solubility of chitin can reach 6.0 wt %. In addition, unlike the reported acidic DES system, this new ternary alkaline DES not only efficiently extracted chitin from crayfish shell waste but also efficiently prepared calcium lactate (CL), which successfully realized the effective recycling of calcium resources. Through 11 sets of extraction conditions, proteins in the crayfish shell were effectively removed, and the yields of chitin and CL remained above 85 and 90%, respectively. Finally, chitin nanofibers were successfully prepared by ultrasonic treatment with extracted regenerated chitin. Further processing of the chitin nanofibers can yield chitin films with high transparency and high tensile strength (63.2 MPa). It provides a novel DES system to dissolve chitin and an environmentally friendly utilization strategy to efficiently extract chitin and prepare CL from crayfish shell waste, thereby producing high-performance functional materials.

A modified structured dry water (SCDW) was prepared by introducing sodium alginate (SA) and calcium L-lactate (CL) into conventional dry water (DW) to mitigate the risks associated with methane–air explosions. The preparation parameters were optimized, yielding uniformly distributed and structurally stable particles. The results demonstrate that SCDW exhibits superior mechanical stability and water retention compared to DW. Pipeline explosion experiments evaluated the suppression performance of six sodium- and potassium-modified SCDWs. At spraying concentrations of 25–100 g/m 3 , all modified SCDWs significantly reduced the maximum explosion pressure and flame propagation distance, outperforming DW. Specifically, 5 wt% KCl-SCDW at 100 g/m 3 reduced the maximum explosion pressure and flame propagation distance by 38.75 % and 24.10 %, respectively, compared to DW. When the spraying concentration exceeded 200 g/m 3 , both parameters stabilized. A quantitative analysis of five explosion-related parameters confirmed that salt-modified SCDWs provided superior suppression performance compared to DW, with potassium-modified SCDWs exhibiting stronger effects than sodium-modified ones, and KCl-SCDW demonstrating the best suppression performance. HSC and Chemkin simulations revealed that SCDW exerts both physical and chemical suppression effects. Physically, DW particles suppress combustion through evaporative cooling, oxygen dilution, energy absorption from particle collisions, and thermal radiation blocking. Chemically, gaseous active species capture and consume H and OH free radicals, interrupting chain reactions through catalytic cycles and generating stable compounds, thereby reducing the maximum explosion pressure and flame propagation speed. Modified SCDWs offer an environmentally friendly, stable, and efficient approach to methane-air explosion suppression.

The large-scale production and use of plastics have led to the widespread distribution of nanoplastics (NPs) in environmental media and the food chain. Among various NPs, positively charged nanoplastics (pNPs) generated through aging processes exhibit enhanced bioaccumulation in living organisms and significantly increased biotoxicity. To achieve rapid detection of pNPs in food and environmental samples, this study synthesized red-emissive fluorescent carbon dots (CAT-RCDs) using 3,4-diaminobenzenesulfonic acid and catechol as precursors. Based on this, a sensing platform capable of fluorescence/colorimetric dual-mode detection of positively charged polystyrene nanoplastics (pPS-NPs) was constructed. The sensor exhibited a linear response from 1 to 50 mg/L (fluorescence) and 5–60 mg/L (colorimetric), with detection limits of 0.58 and 1.04 mg/L, respectively. Recovery rates of 90.91–104.80 % confirmed its accuracy. This dual-mode strategy allows visual detection and cross-validation of pPS-NPs, providing a rapid screening tool and a foundation for advanced nanoplastic sensing technologies.

While increasing dietary calcium (Ca) intake can reduce the oral bioavailability of heavy metal(loid)s, it remains unclear whether a series of Ca compounds can simultaneously reduce the oral bioavailability of As and Pb from soil. The influence of eight Ca compounds on As and Pb bioaccessibility in soils was determined using an in vitro gastrointestinal model, following which an in vivo bioassay was used to determine the most effective Ca compounds on As and Pb bioavailability. The results showed that, while CaHPO 4 was the most effective in reducing Pb bioaccessibility in gastric (from 19.0 to 92.3% to 14.3‒66.4%) and intestinal (from 0.18 to 17.5% to 0.00‒3.53%) phases, it conversely exhibited the strongest capacity to enhance As bioaccessibility. However, the addition of Ca acetate reduced the Pb bioaccessibility in the gastric phase and As bioaccessibility in the intestinal phase. More importantly, the Ca acetate (~ 200 mg Ca kg -1 ) was the most effective in reducing relative bioavailability of As and Pb based on mouse bioassay. Our finding verify the efficacy of Ca acetate in mitigating the oral bioavailability of As and Pb. This study lays a theoretical foundation for the targeted use of optimal Ca compounds to mitigate human exposure risks to environmental As and Pb.

Replacing high-performance synthetic fibers with sustainable bio-derived alternatives is critical for mitigating microplastic pollution but remains limited by the inferior mechanical performance of biomass-derived fibers. Here, we present bioinspired cellulose metafibers (Meta-CFs) enabled by a scalable hydrodynamic twisting strategy, wherein an asymmetric microfluidic field precisely guides the formation of continuously twisted architectures within a chemically cross-linked network, thereby locking in the ordered configuration and markedly suppressing defect accumulation. Multiscale experiments and simulations reveal that this strategy promotes efficient stress delocalization and cooperative load transfer. The resulting Meta-CFs achieve an unprecedented maximum tensile strength of 3.29 GPa (average 3.06 ± 0.23 GPa) and a toughness of 349.5 MJ m −3 , simultaneously rivaling the strength of high-performance synthetic fibers and the toughness of natural spider silk. Furthermore, encapsulating multiple individual Meta-CFs with calcium alginate effectively scales up the bundle diameter while preserving GPa-level strength and full biodegradability. This upscaling strategy enables large-diameter structural applications, as demonstrated by durable trimmer lines that avoid the generation of persistent agricultural microplastic residues, thereby establishing a viable pathway toward high-performance, sustainable material alternatives.

Water-lubricated bearings working at low velocity and high contact pressures face critical tribological challenges, especially the thinning and failure of the hydrodynamic water film leads to the direct contact of surface asperities, resulting in severe wear and friction noise. To solve these issues, this study designs an innovative hydrogel-microencapsulated polyether ether ketone (PEEK) composite through the combination of hydrogel microcapsules into the PEEK matrix. This water lubricated composite achieves a 64 % reduction in the coefficient of friction and a one-order-of-magnitude decrease in the wear rate, significantly enhancing the polymer's lubrication performance under severe operating conditions. The mechanism behind the lubrication enhanced performance is attributed to the in-situ formation of hydrogel lubricating films on the PEEK surface. This work proposes an innovative ‘rupture-grow’ lubricating strategy for developing polymer-based bearing materials to address critical tribological challenges.

The extensive use of plastic pipes has brought about severe environmental pollution and posed risks to human health, thereby giving rise to an urgent need for the development of environmentally friendly alternatives. Herein, a tough, eco-friendly, and biodegradable cellulose pipe (BCP) is reported. The preparation involved dissolving and casting cellulose into membranes, followed by bonding, and shaping the membranes through sodium alginate to create cellulose pipes. Owing to its highly ordered molecular structure and low-density characteristics, the as-prepared BCP exhibited a specific modulus of 24.65 MPa cm 3 g −1 , which surpassed that of commercial plastic-based pipes, such as ABS, PA, and PE. Furthermore, the BCP demonstrated high deformation adaptability, effectively maintaining water flow performance in complex environments and thus enhancing agricultural productivity. Notably, the BCP can be completely degraded within 49 days, meeting the requirements for practical use. This excellent biodegradability makes the pipe fabricated from natural plant-based materials an environmentally friendly alternative to plastic pipes. Graphical abstract

In this study, the effect of calcium ions (Ca 2+ ) on the astringency sensation in green tea infusion was explored using sensory evaluation, in vitro oral soft tribology, and targeted metabolomics. Ca 2+ enhanced the astringency intensity (from 2 to 6) and the turbidity (from 10.0 to 83.3), and decreased the particle size (from 1468.0 to 817.65) in cold-brewing tea. Catechins influenced the astringent sensation in the presence of Ca 2+ and the content of (−)-Epicatechin, (−)-Epigallocatechin, and (−)-Epigallocatechin gallate (EGCG) solution in green tea infusion after oral processing all reduced. The friction coefficient of hot-brewed tea (μ, 1.6–2.8) was greater than that of cold-brewed tea (μ, 1.0–2.6), and EGCG increased with the enlarged Ca 2+ concentrations. Ca 2+ increased the astringency mainly through catechins and saliva lubrication. The in vitro soft oral tribology could be usefully explored the enlarged astringency sensation by Ca 2+ , and applied to the astringency regulation of beverages.

Fresh spirulina microcapsules (SP-MICs) are a viable strategy to prolong the preservation of fresh spirulina . This study aims to investigate the effects of SP-MICs on noodle quality, focusing on physicochemical properties and wheat gluten structures. Compared to the control group, the addition of 3 % SP-MICs significantly improved the sensory and textural properties of the noodles. Chewiness and hardness increased by 14.40 % and 32.36 %, respectively. In terms of glutenin subunits, HMS and B/C-LMS contents increased by 6.10 % and 5.39 %, respectively. Additionally, the gliadin-to-glutenin ratio reached its lowest at 1.19. Surface hydrophobicity decreased by 6.41 %, disulfide bond content increased by 31.60 %, and non-covalent interactions (hydrogen bond and hydrophobic interactions) were enhanced. The secondary structure of gluten protein became more ordered, with a 6.86 % increase in β-sheet content and a 1.10 % decrease in random coil content. SEM and CLSM results showed that 3 % SP-MICs significantly reinforced the gluten network and protein-starch cross-linking.

Bacterial cellulose (BC) has been extensively applied to fabricate advanced biomaterials, although it remains challenging due to its poor toughness and water stability. Herein a genetically engineered protein-conjugated synthetic polymer is designed to improve BC film's strength and flexibility. Initially, the hybrid polymer is constructed by grafting Family 3 carbohydrate-binding modules (CBM3) to amphoteric polyacrylamide polymer (AmPAM), one of the paper industry's most widely used dry-strength agents. Then, the conjugated polymer is added to the culture medium of BC growth, enabling it to incorporate into the matrix of cellulose chains. The results show that the BC film modified by CBM3-AmPAM exhibits superior mechanical properties, registering 9.94 % in strain and 13.8 MJ/m 3 in toughness, 12.1 and 8.0 folds over the sample with AmPAM addition only. Additionally, the BC film improved by CBM3-AmPAM has excellent gas resistance, thermal stability, and environmental endurance. The adsorption of CBM3-AmPAM on BC film revealed by quartz crystal microbalance with dissipation monitoring indicates that the adsorbed layer is thin and rigid, suggesting the strong interaction between the conjugated polymer and BC substrate. As a result of this reinforcing strategy, BC composites can be used in a wider range of applications.

Calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate are of considerable importance for the development of calcium-fortified soymilk products. This study aimed to investigate the characteristics and stabilities of calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate. When the concentration of sodium tripolyphosphate ranged from 0 to 0.6%, the emulsion potential and emulsification activity index gradually increased to 35.5 mV and 71.7 ± 0.8%, while the particle size and flocculation index progressively decreased to 756.2 ± 41.3 nm and 16.21%, respectively. However, when the concentration exceeded 0.6%, these characterization data plateaued. Microstructural analysis revealed a uniform distribution of droplets. Raman spectroscopy showed an increase in the ordered structure of proteins in the emulsion. Additionally, the centrifugal, thermal, and storage stabilities of the emulsion were enhanced. These findings offer insights into the properties of calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate and may contribute to expanding their utilization in emulsions and soy products.
