How to construct a new electrode/electrolyte interface structure in solid-state batteries (SSBs), enhance interface stability, and improve the cycling performance of SSBs is a great challenge for the development of SSBs. Here, an all-in-one “interface-free” structure was developed. This interfacial structure constructs a full-interface hydrogen bonding network through the abundant hydrogen bond donors and acceptors in the cathode and electrolyte to enhance the interfacial stability and avoid interfacial failure during charging and discharging, and generates cathode–electrolyte interface (CEI) in-situ to effectively regulate zinc ion transport. Square cells assembled in this structure are stabilized for 100 cycles at a current density of 0.1 mA cm −2 . This integrated electrode provides a new idea for the long stable cycle of SSBs.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.2 mA after 1000 compression cycles, with good current stability, and is widely used in the field of monitoring human movement. Furthermore, the water contact angle of CA/SA/MTMS/MXene aerogel is maintained above 120° and still shows strong hydrophobicity, which implies that the aerogel has the piezoresistive sensing potential under sweating conditions of the human body.

Intelligent food packaging, as an innovative direction for enhancing food quality monitoring capabilities, has garnered extensive attention among consumers and in the research community in recent years. This study constructed composite film materials using sodium alginate (SA) and polyvinyl alcohol (PVA) as the matrix, loaded with the natural active ingredient curcumin to evaluate the potential of the composite film as an indicator of shrimp freshness. The results revealed that the composite film had a thickness of less than 0.1 mm and could effectively block ultraviolet-visible light. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) analyses indicated that curcumin was uniformly distributed within the film matrix. This composite film exhibited strong antioxidant activity (ABTS scavenging rate: 82 %; DPPH scavenging rate: 47.9 %) and reliable pH-responsive characteristics, turning purple or reddish-brown when the pH exceeded 10. This property provides a simple and intuitive method for detecting changes in food quality. In terms of monitoring shrimp freshness, the composite film effectively indicated spoilage. The SA-PVA-CUR30 film changed from light yellow to purple on the fourth day, with a significant increase in the ΔE value (from 34.52 to 51.89), demonstrating optimal indicating performance. In conclusion, this pH-sensitive composite film offers new insights for innovation in food packaging and lays a foundation for the precise control of food quality.

Here, we report on the effect of functional copolymer poly(N-isopropylacrylamide-co-4-vinyl-phenylboronic acid) (NIBA) on the rheology and network structure formed by sodium alginate (SA) through linear and nonlinear viscoelasticity measurements. The hydrogel moduli at pH 3 increased with increasing NIBA addition, while the yield point decreased. Furthermore, these hydrogels showed strain-softening behavior, weak G″-overshoot marking the onset of nonlinearity, and good self-healing properties after large deformation. The zero-strain nonlinearity parameter (Q 0 ) was found to be more sensitive to NIBA-addition than the linear viscoelastic properties. The blends showed a clear peak in the startup test except for SA alone and the peak intensity increased with increasing NIBA-concentration. Finally, based on all data, gelation mechanism and interaction of SA and NIBA will be clarified.

Sprayable wound dressings, with their exceptional flexibility and superior adaptability to wounds of varying sizes and irregular shapes, offer promising therapeutic potential for large-area and complex wounds. Herein, an antioxidant sprayable dressing (SA/multi-C60-O) was designed and prepared through covalent cross-linking between a water-soluble fullerene derivative (multi-C60-O) and sodium alginate. The cross-linked structure was confirmed by Fourier-transform infrared spectroscopy (FTIR) and demonstrated excellent radical scavenging performance, achieving scavenging rates as high as 99.7%, 95.2%, and 97.8% against DPPH, ABTS, and hydroxyl radicals (·OH), respectively, after 24 h of reaction at a concentration of 2 mg/mL. Intracellular ROS detection confirmed the antioxidant activity at the cellular level. Moreover, the dressing exhibited potent antibacterial activity against Staphylococcus aureus and Escherichia coli with rates exceeding 95% at 2 mg/mL, along with favorable cytocompatibility and hemocompatibility. Animal experiments further revealed that the dressing significantly accelerated wound contraction and healing. Based on H&E and Masson’s trichrome staining, along with immunohistochemical analysis, we demonstrated that the dressing can effectively promote skin regeneration, collagen deposition, and neovascularization by alleviating oxidative stress and inflammatory responses, thereby achieving superior healing outcomes.

In this study, carbon dots (CDs) were prepared by a one-pot hydrothermal method using tempo-oxidized cellulose nanocrystals (TOCNC) and polyethylenimine (PEI). The CDs were self-assembled with a microsphere adsorbent prepared using TOCNC and sodium alginate (SA). CDs-TOCNC/SA—an environmentally friendly, fluorescent-sensitive, and recyclable microsphere adsorbent—was obtained. FTIR analysis showed that PEI successfully modified the CDs. In addition, the fluorescence quenching of CDs was observed when the concentration of Pb 2+ was 0.0001–100 mg/L, indicating that CDs can dynamically monitor Pb 2+ . CDs-TOCNC/SA can produce blue fluorescence under 365 nm UV light and selectively and efficiently adsorb Pb 2+ . When the concentration of Pb 2+ was 0.0001–100 mg/L, fluorescence quenching of the adsorbent was observed, indicating that CDs-TOCNC/SA could visually adsorb Pb 2+ . The adsorption isotherm and kinetic parameters show that the adsorption process conforms to the Langmuir isotherm model at 298 K, and the maximum adsorption capacity of Pb 2+ was 190.1 mg/g at pH = 5. Moreover, CDs-TOCNC/SA could still obtain 78.99 % Pb 2+ after five sorption-desorption cycles. The adsorption mechanism may involve ion exchange, electrostatic attraction, intra-particle diffusion, and chemical complexation.

Dye wastewater is characterized by its complex composition, high chromaticity, and significant toxicity, posing a major challenge in industrial wastewater treatment. Adsorption has emerged as an indispensable technology for dye removal due to its operational simplicity, environmental compatibility, and cost-effectiveness. In this work, a gel microsphere adsorbent (PS/P-γ-CD/Hec-XTAB) was prepared by incorporating sodium alginate with epichlorohydrin-crosslinked γ-cyclodextrin polymer and hectorite modified with cationic surfactants of varying chain lengths. The adsorbent was applied to remove typical cationic dyes─methylene blue (MB) and rhodamine B (RhB)─from aqueous solution. The optimized material, PS/P-γ-CD/Hec-CTAB0.4, exhibited a high specific surface area (374.7008 m2/g) and showed maximum adsorption capacities of 139.1564 mg/g and 122.663 mg/g for methylene blue and rhodamine B respectively at pH 7 and 25 °C. The adsorption kinetics followed a pseudo-first-order model, while equilibrium data were well described by the Langmuir isotherm. The process was found to be endothermic and spontaneous, mainly governed by hydrogen bonding, electrostatic interactions, host−guest encapsulation, and pore filling. Overall, this study presents an eco-friendly and economically viable adsorbent with promising potential for practical application in dye wastewater treatment.

In this study, Fe 0 -Fe 3 O 4 nanocomposites embedded polyvinyl alcohol (PVA)/sodium alginate (SA) beads were synthesized, which exhibited an excellent physical properties and catalytic reactivity, and a robust performance of post-separation (complete separation using a simple grille) and reusability (efficiency of 69.8% after four runs) in Cr(VI) removal. 5.0 wt% PVA with 1.5 wt% SA was the optimal proportion for beads molding, and the followed acidification and reduction treatments were critical to ensure high mechanical strength and high Cr(VI) removal ability of beads. Effects of Fe 0 and Fe 3 O 4 mass fraction, initial pH and Cr(VI) concentration on final removal efficiency were also evaluated. Merely 0.075 wt% Fe 0 together with 0.30 wt% Fe 3 O 4 was sufficient to deal with 20 mg L −1 Cr(VI) solution. The efficiency decreased from 100 to 79.5% as initial Cr(VI) increased from 5 to 40 mg L −1 , while from 99.3 to 76.3% with increasing pH from 3.0 to 11.0. This work provides a practical and high-efficient method for heavy metal removal from water body, and simultaneously solves the problems in stabilization, separation and regeneration of Fe 0 nanoparticles.

Sodium alginate is a polyanionic natural polysaccharide polymer widely used in tissue engineering. However, the lack of binding domains for interaction with cells limits its application in regenerative medicine. This study designed a kind of galactosylated sodium alginate (G-SA) material with improved galactose grafting rate by EDC/NHS activation of carboxyl groups in MES buffer and subsequently cross-linking by Ca2+ aims to enhance the adherence behavior of HepG2 cells on alginate substrate. The synthesized G-SA was characterized by Fourier transform infrared spectra and nuclear magnetic resonance spectroscopy. G-SA exhibited good biocompatibility and significantly enhanced the adhesion behavior of HepG2 cells on its surface. Furthermore, we demonstrated that the effect of G-SA concentration in enhancing cell adhesion was diminished at higher than 2% w/v. Finally, the suitability of G-SA material is investigated for 3D printing, demonstrating that HepG2 cells could maintain high viability and excellent printability in the interior of the gel. In addition, cells could multiply and grow into cell spheroids with an average size of 200 μm in G-SA scaffolds. These results indicated that galactosylated sodium alginate material could be used as a 3D culture system that could be effective for engineering liver cancer models.

This study investigates the waterproof layer formed by beeswax (BW) to improve the hydrophobicity of sodium alginate/black soybean seed coat anthocyanin/cellulose nanocrystal indicator films. The concentrations of BW and the fabrication method of the waterproof layer, including spraying, coating (CO), and soaking, were optimized. The results showed that the optimal concentration of BW in the waterproof layer was 5% owing to its high water contact angle of 111.5°. Different methods of fabricating waterproof layers with BW led to the formation of particles of different sizes on the microscopic film surface. Hydrophobic films with a waterproof layer of BW-CO had high transmittance and pH sensitivity, ensuring the basic properties of indicator films. Meanwhile, they exhibited excellent water barrier properties based on the water contact angle, water vapor adsorption, water vapor permeability, water content and water solubility. In particular, these films remained highly hydrophobic after 10 days of storage at 100% humidity, with a water contact angle of 108.3°. The findings indicated that hydrophobic sodium alginate/black soybean seed coat anthocyanin/cellulose nanocrystal indicator films were prepared using BW, which improved their potential application in intelligent food packaging.

This study investigates the rheological properties of dual-network hydrogels based on acrylamide and sodium alginate under large deformations. The concentration of calcium ions affects the nonlinear behavior, and all gel samples exhibit strain hardening, shear thickening, and shear densification. The paper focuses on systematic variation of the alginate concentration—which serves as second network building blocks—and the Ca2+-concentration—which shows how strongly they are connected. The precursor solutions show a typical viscoelastic solution behavior depending on alginate content and pH. The gels are highly elastic solids with only relatively small viscoelastic components, i.e., their creep and creep recovery behavior are indicative of the solid state after only a very short time while the linear viscoelastic phase angles are very small. The onset of the nonlinear regime decreases significantly when closing the second network (alginate) upon adding Ca2+, while at the same time the nonlinearity parameters (Q0, I3/I1, S, T, e3/e1, and v3/v1) increase significantly. Further, the tensile properties are significantly improved by closing the alginate network by Ca2+at intermediate concentrations.Keywords:acrylamide;sodium alginate;double network hydrogel;large amplitude oscillatory shear;Fourier transform rheology

In recent years, the incidence of inflammatory bowel disease has gradually increased. Traditional drugs can reduce inflammation, but cannot be targeting released and often require the coordination with delivery systems. However, a good targeting performance delivery system is still scarce currently. Inflammation can trigger oxidative stress, producing large amounts of oxides such as nitric oxide (NO). Based on this, the present experiment innovatively designed a hydrogel delivery system with NO response that could be inflammation targeting. The hydrogel is composed of sodium alginate modified with glycerol methacrylate, crosslinked with NO response agent by photo-crosslinking method, which have low swelling (37 %) and good mechanical properties with a stable structure even at 55 °C. The results of in vitro digestion also indicated that the hydrogel had a certain tolerance to gastrointestinal digestion. And in the NO environment, it was interestingly found that the structure and mechanical properties of the hydrogels changed significantly. Moreover, hydrogels have good biocompatibility, which ensures their safe use in vivo. In conclusion, this NO-responsive-based delivery system is feasible and provides a new approach for drugs and active factors targeting delivery in the future.
