A fully biobased sodium-alginate/soy protein isolate gel foam was successfully prepared. • Thermal resistance performance test demonstrate that SS-GF treated coal reaches a maximum temperature reduction of 84.2%. • The fire-extinguishing efficiency of SS-GF increased by 73%. • The mechanism by which SS-GF inhibits coal spontaneous combustion was revealed. Coal spontaneous combustion endangers mine safety gravely. Coal spontaneous combustion fires not only release a large amount of toxic smoke, causing environmental pollution, but also seriously threaten the safety of mines. Gel foam materials possess favorable flowability, surface coverage and fracture-sealing capacity, and have shown promising application prospects in the prevention and control of coal spontaneous combustion. However, most gel foams have limited stability and water retention capacity. To address this issue, this study developed a high-stability gel foam (SS-GF) with sodium alginate (SA) and soy protein isolate as raw materials. SS-GF has excellent stability, water retention capacity and fire-extinguishing performance, thereby efficiently inhibiting coal spontaneous combustion. Compared with SA gel foam, SS-GF has significantly improved in water retention performance and structural integrity. SS-GF inhibited the heat accumulation on the surface of coal. Compared with raw coal, the maximum temperature was reduced by 84.2%. At 200℃, the CO inhibition efficiency of SS-GF treated coal reached 57.83%, and the oxygen consumption rate decreased by 40.3% compared with raw coal. Furthermore, SS-GF rapidly reduced the high-temperature coal from 963.73°C to 30°C within 100 min, improving the fire-extinguishing efficiency by 73% with no re-ignition. SS-GF can effectively prevent coal from contacting oxygen, inhibit the formation of active functional groups in coal, and delay the process of coal spontaneous combustion. This study provides a green and efficient strategy for the prevention and control of coal spontaneous combustion. Download: Download high-res image (186KB) Download: Download full-size image

This study reports the development of a novel, recoverable photocatalyst, Ti 3 C 2 T x @TACs-SA, for the efficient degradation of carcinogenic disinfection byproducts (DBPs) in drinking water. The composite was fabricated via a simple, eco-friendly strategy involving the growth of transition metal atom clusters (TACs: Co, Fe, Ni) on MXene (Ti 3 C 2 T x ) nanosheets, followed by incorporation into a crosslinked sodium alginate (SA) biopolymer matrix. Comprehensive characterization via SEM-EDX, XPS, XRD, HAADF-STEM, XANES, TGA, BET, and DFT confirmed the composite's structure and properties. The photocatalytic performance of the composite was systematically investigated for the degradation of DBPs in drinking water. Key experimental conditions, including pH, initial pollutant concentration, irradiation time, and thermodynamic study, were carefully optimized to determine their effect on the overall degradation performance. Five common DBPs, trihalomethanes (THMs), haloacetic acids (HAAs), haloacetonitriles (HANs), halonitromethanes (HNMs), and dichloroacetaldehyde (DCAL), were chosen as target contaminants. The composite exhibited excellent photocatalytic activity across a wide pH range. At neutral pH (7.0) and an initial DBP concentration of 100 μg/L, the photocatalyst achieved degradation efficiencies of 83.8% for THMs, 84.4% for HAAs, 85.3% for HANs, 83.8% for HNMs, and 83.4% for DCAL after 60 min of UV irradiation. At acidic pH 3.0, removal efficiencies were slightly reduced to 80.1%, 78.3%, 79.3%, 77.6%, and 75.8%, respectively. In contrast, alkaline conditions significantly enhanced DBPs removal, achieving 90.0%, 92.0%, 93.6%, 95.4%, and 96.0% for the respective contaminants. These findings demonstrate the strong potential of the Ti 3 C 2 T x @TACs-SA composite as a practical and efficient photocatalyst for eliminating carcinogenic DBPs from water.

We herein developed sodium alginate (SA)-chitosan (CS) dual-network liposome gel beads (S-C-L) using electrostatic complexation to co-deliver of folic acid (FA) and vitamin E (VE). The effects of varying SA-to-CS mass ratios (9:1, 8:2, 7:3, 6:4, 1:1, 4:6, and 3:7) on beads' microstructure, physicochemical traits, and encapsulation performance were systematically assessed. The findings indicated that even minimal CS incorporation markedly improved the mechanical strength, stability and overall functionality of the liposome gel beads compared with those made solely from SA (S-L). At a 9:1 SA-to-CS ratio, the beads displayed uniform, spherical shapes with compact crosslinked networks and achieved the highest encapsulation efficiencies (FA: 87.92%; VE: 92.94%). In addition, the SA-CS dual-network system allowed controlled lipid digestion and reversible structural transitions, supporting efficient intestinal release of both nutrients (FA: 86.57%; VE: 84.07%). Overall, this work offers a promising framework for designing carbohydrate-based dual-network liposome gels for the simultaneous delivery of hydrophilic and lipophilic bioactive components.

A ternary SF-SA-CS biomass sponge (SSC) was fabricated via electrostatic and hydrogen bonding. • SSC exhibits high adsorption capacity and selectivity for DCF-Na. • Mechanism studies confirm enrichment driven by hydrogen bonding and electrostatic forces. • SSC-HPLC method enables sensitive monitoring of DCF-Na pharmacokinetics in mouse plasma. • SSC-HPLC method provides a robust tool for future in vivo pharmacodynamics of drugs. Diclofenac sodium (DCF-Na) is a widely used non-steroidal anti-inflammatory drug. However, monitoring its dynamic behavior in vivo remains challenging due to the complexity of biological matrices. Herein, a novel biomass sponge adsorbent (SSC) was successfully fabricated via the composite of silk fibroin (SF), sodium alginate (SA), and chitosan (CS) through electrostatic and hydrogen bonding interactions. The resulting SSC exhibited a uniform three-dimensional porous architecture with a specific surface area of 8.64 m 2 ·g −1 and a mesoporous structure (average pore size 17.0 nm). Benefiting from the synergistic effect of abundant amino, carboxyl, and hydroxyl groups, SSC achieved rapid adsorption equilibrium within 60 min and a high saturated adsorption capacity of 165.8 mg·g −1 . Kinetic and isothermal studies revealed that chemisorption and monolayer adsorption were the dominant mechanisms. Significantly, SSC demonstrated remarkable selectivity toward DCF-Na and excellent anti-interference capability in complex coexisting systems, as confirmed by comparative adsorption experiments and cluster analysis. Mechanistic investigations combining spectroscopic analysis and molecular simulations verified that the adsorption was primarily driven by hydrogen bonding and electrostatic interactions. Furthermore, an SSC-HPLC method was developed for the determination of DCF-Na in plasma, yielding a wide linear range, high precision ( RSD < 0.793%), and satisfactory accuracy (recovery: 102%–108%). The established method was successfully applied to monitor the plasma drug concentration of DCF-Na in mice via high-performance liquid chromatography. This work presents an efficient, stable, and environmentally friendly sample pretreatment strategy based on a biomass adsorbent for monitoring of drug concentrations in biological matrices.

An environmental-friendly composite films containing waste fish scale-derived gelatin (FSG), sodium alginate (SA) and carvacrol loaded ZIF-8 (CV@ZIF-8) nanoparticles were designed and fabricated to develop active food packaging materials capable of sustained antibacterial activity. The microstructure and physicochemical properties of the FSG/SA/CV@ZIF-8 composite films were investigated. The incorporation of CV@ZIF-8 into FSG/SA matrix significantly enhanced the UV-light blocking and the elongation at break, improved water resistance and reduced water vapor permeability, and improved the thermal stability of composite film. The FSG/SA/CV@ZIF-8 film not only exhibited strong antioxidant activity with DPPH radical scavenging rate of 92.35 %, but also showed the satisfactory and long-acting antibacterial ability against E. coli and S. aureus due to slow release of CV from composite film. Strawberry preservation experiment revealed that FSG/SA/CV@ZIF-8 film decelerated the texture deterioration and retarded the growth of spoilage microorganism, resulting in the prolonged shelf-life of 8 days under ambient condition, indicating its promising application prospect in food preservation packaging.

The effect of gum tragacanth (GT) and sodium alginate (SA) active coatings incorporated with epigallocatechin gallate (EGCG, 0.16%, 0.32% and 0.64%, respectively) on the quality of large yellow croaker fillets was evaluated during superchilling storage at -3 ℃ for 42 days. The results revealed that the GT-SA-EGCG active coatings delayed the microbial spoilage via reducing the numbers of total viable counts, Pseudomonas spp. and psychrophiles bacteria, retarded degradation of the physical properties of water holding capacity, cooking loss, color, odor and texture. GT-SA-EGCG coatings could also maintain the fillets’ freshness by keeping lower total volatile basic nitrogen, K value and histidine content, inhibiting myofibrillar protein degradation during superchilling storage. These results suggested that the active coatings embedded with GT-SA-EGCG could be used as a preservative to enhance the quality of large yellow croaker and prolong the shelf life by 7-14 days during superchilling storage at -3 ℃.

Efficient removal of contaminants, like heavy metal ions and dyes, from wastewater by eco-friendly and low-cost adsorbent is highly desirable. Herein, a green aerogel was prepared using sodium alginate/carboxylated chitosan/montmorillonite (MSC-P) as the basic framework, followed by polyethyleneimine functionalized and Ca 2+ post-crosslinking. The multi-crosslinked aerogel exhibited the excellent adsorption capacity towards methylene blue (MB), Congo red (CR) and Cu(II), with the q m being 723.97 mg/g, 1573.21 mg/g and 203.99 mg/g, respectively. The mathematical model suggested that the adsorption process for MB fitted pseudo-first-order kinetics model better, whereas the CR and Cu (II)’s adsorption process were conformed to pseudo-second-order kinetics model. Moreover, the adsorption isotherm for three contaminants could be well described by Langmuir model, suggesting that the adsorption process was spontaneous and mainly controlled by monolayer coverage. Moreover, MSC-P aerogel exhibited good reusability as the removal efficiencies for MB and Cu(II) were 85.16 % and 51.4 % after ten cycles of adsorption–desorption, respectively. Importantly, it possessed considerable simultaneous removal ability for binary system mixed dyes. In combination of FTIR analyses, it was found that electrostatic attraction, hydrogen bonding, coordination and cation exchange were the main adsorption mechanisms involved. Therefore, the as-prepared aerogel can be considered as a promising adsorbent for the treatment of wastewater.

In this paper, a reinforced Biomass Gel Artificial Muscle (BGAM) was fabricated by natural polysaccharide of Sodium Alginate (SA) doped with an Ionic Liquid (IL) of 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIm][BF 4 ]). Micro-nano regulation effect and reinforcement mechanism of IL doping content on electromechanical response performance of BGAM were researched during a single cycle and repeated cycles. Then, a green fabrication process and a set of valid test methods for BGAM were proposed in detail. The experimental results showed that when IL doping content was 4 mL, the BGAM achieved optimal modification, with a porosity of 70.47%, where it internally adopted the porous polymer structure of ion channels. Additionally, specific capacitance of BGAM attained a maximum value of 126.98 mF/g, and the inner resistance and elastic modulus reached minimum values of 2.018 Ω and 1.871 MPa, separately. Thus, the optimal working life and output-force density values, namely, 1720 s and 13.072 mN/g, respectively, were also determined for the BGAM.

Sodium alginate (SA)-pectin (PEC)-whey protein isolate (WPI) complexes were used as an emulsifier to prepare β-carotene emulsions, and the encapsulation efficiency for β-carotene was up to 93.08%. The confocal laser scanning microscope (CLSM) and scanning electron microscope (SEM) images showed that the SA-PEC-WPI emulsion had a compact network structure. The SA-PEC-WPI emulsion exhibited shear-thinning behavior and was in a semi-dilute or weak network state. The SA-PEC-WPI stabilized β-carotene emulsion had better thermal, physical and chemical stability. A small amount of β-carotene (19.46 ± 1.33%) was released from SA-PEC-WPI stabilized β-carotene emulsion in simulated gastric digestion, while a large amount of β-carotene (90.33 ± 1.58%) was released in simulated intestinal digestion. Fourier transform infrared (FTIR) experiments indicated that the formation of SA-PEC-WPI stabilized β-carotene emulsion was attributed to the electrostatic and hydrogen bonding interactions between WPI and SA or PEC, and the hydrophobic interactions between β-carotene and WPI. These results can facilitate the design of polysaccharide-protein stabilized emulsions with high encapsulation efficiency and stability for nutraceutical delivery in food and supplement products.Keywords:β-carotene;polysaccharide;protein;encapsulation;emulsion

With the rapid development of industry, efficient removal of heavy metal ions such as lead ions in wastewater has been attracted much attention in the fields of water treatment and environmental remediation. Herein, a novel polymer composite adsorbent material EDTMPA-P/A has been successfully prepared through the combination of sodium alginate and waste para aramid using low-temperature esterification method, and the subsequent modification of EDTMPA (ethylene diamine tetra (methylene phosphonic acid)). The static saturation adsorption experiment verified that EDTMPA-P/A had significant adsorption performance for lead ions, hence, EDTMPA-P/A has been employed to adsorb lead ions from aqueous solutions, and the relevant adsorption behaviors of the polymer composite adsorbent for lead ions have been investigated in detail. The adsorption isotherm of EDTMPA-P/A was consistent with the Langmuir isotherm model, and the corresponding kinetics data were well fitted by the pseudo-second-order kinetic model. The maximum adsorption capacity of EDTMPA-P/A obtained by Langmuir isotherm for lead ions was 315.46 mg/g at 35 °C, which was much higher than other adsorbents reported in the literatures. Moreover, the adsorption thermodynamic parameters Δ G , Δ H and Δ S of EDTMPA-P/A for lead ions were 1.92 kJ mol −1 (35 °C), 14.69 kJ mol −1 , and 41.74 J K −1 mol −1 , respectively. The research results indicated that EDTMPA-P/A could be evaluated as a novel efficient adsorbent with high efficiency in wastewater treatment and removal of lead ions, and it is great application prospect that EDTMPA-P/A with facile esterification synthesis at low temperature, modification process and excellent adsorption performance, therefore, could be used as a high efficient adsorbent for lead ions removal, which also has simultaneously achieved the reuse object of waste para aramid.

The inflammatory environment of periodontitis with bacteria, excessive reactive oxygen species (ROS) and limited regenerative capacity of alveolar bone makes reconstruction of periodontium become a huge challenge. The present strategies, such as local debridement and antibiotic injection, are difficult to solve above problems completely. Thus, to reverse the progression of the disease, Ca 2+ -tannic acid nanocomposites loaded into injectable sodium alginate/4-arm polyethylene glycol-lipoic acid hydrogel (CaTA@Gel) were fabricated, including Ca 2+ ‑sodium alginate (SA) ionic crosslinking and radical polymerization of lipoic acid-modified 4-arm polyethylene glycol (PEG-SS 4 ) under UV illumination. In our results, the double networks of hydrogel not only had good mechanical property, but also sustainedly released CaTA nanocomposites which could inhibit bacteria, scavenge ROS due to TA, and promote osteogenesis of bone mesenchymal stem cells (BMSCs) via Ca 2+ . The antibacterial rates of CaTA (1 mg/mL) against E. coli and S. aureus were 97.3 ± 1.25 % and 96.7 ± 2.57 %, respectively. Meanwhile, ·OH and ·O 2− could be inhibited obviously by CaTA (100 μg/mL), whose inhibition rate were 59.6 ± 2.98 % and 62.4 ± 3.12 %, respectively. Finally, the up-regulation of osteogenetic genes and successful alveolar bone regeneration in rat models indicated this injectable nanocomposite hydrogel provided a promising strategy for the treatment of periodontitis.

Seafood is highly perishable and has a short shelf-life. This study investigated the effect of chitosan and alginate (CH-SA) coating combined with the cell-free supernatant of Streptococcus thermophilus FUA329 (CFS) as a preservative on the quailty of white shrimp (Litopenaeus vannamei) refrigerated at 4° for 0, 3, 6, 9, 12, 15 days. Freshly shrimps were randomly divided into four groups: the CFS group (400 mL); the CH-SA group (1% chitosan/1% alginate); the CFS-CH-SA group (1% chitosan/1% alginate with 400 mL CFS) are treatment groups, and the control group (400 mL sterile water). The CFS–CH–SA coating effectively suppressed microbial growth total viable count and chemical accumulation (pH, total volatile basic nitrogen, thiobarbituric acid reactive substance) compared with the control. Additionally, the CFS–CH–SA coating improved the texture and sensory characteristics of shrimp during storage. The coated shrimp exhibited significantly reduced water loss ( p < 0.05). The combination of CH–SA coating with CFS treatment can extend the shelf life of shrimp. Practical Application Recently, edible films have received more consideration as a promising method to enhance the shelf life of seafood. The presence of Lactic acid bacteria metabolites in edible films reduces spoilage and improves consumer health. Our findings encourage the application of edible coating incorporated with cell-free supernatant of Streptococcus thermophilus FUA 329 to design multifubctional foods and preserve the qualities of shrimp.
