Food-grade compound-stabilized high-internal-phase Pickering emulsions (HIPEs) have received widespread attention in food industry and functional foods. However, challenges are still there regarding the inclusion of active substances and quickly processing molding for food manufacturing. Herein, we used zein , tannic acid (TA) and sodium alginate (SA) to synergistically increase the stability of HIPEs. Owing to electrostatic, hydrophobic and hydrogen-bond interactions among protein, polyphenol and polysaccharide , Zein-TA-SA composite particles-stabilized HIPEs (ZTS-HIPEs) exhibited good pH and ionic strength stability. The HIPEs could further be used to load and solubilize β-carotene, while significantly improved the retention of β-carotene in different environments. Simulated in vitro digestion experiments showed that the release rate of free fatty acids and bioaccessibility of β-carotene in HIPEs were significantly improved, indicating that HIPEs might achieve efficient delivery of β-carotene in the gastrointestinal environment. In addition, the ZTS-HIPEs could be 3D printed as food-grade inks due to their good rheological properties as the printed models showed good precision and stability. In summary, the ZTS-HIPEs prepared in this study could be used not only as an effective delivery carrier of β-carotene, but also as a potential ink for 3D printing. The research findings in this study are expected to provide novel insight on HIPEs for nutrition delivery systems and future food manufacturing.

The mechanism underlying the ability of rice to germinate underwater is a largely enigmatic but key research question highly relevant to rice cultivation. Moreover, although rice is known to accumulate salicylic acid (SA), SA biosynthesis is poorly defined, and its role in underwater germination is unknown. It is also unclear whether peroxisomes, organelles essential to oilseed germination and rice SA accumulation, play a role in rice germination. Here, we show that submerged imbibition of rice seeds induces SA accumulation to promote germination in submergence. Two submergence-induced peroxisomal Oryza sativa cinnamate:CoA ligases (OsCNLs) are required for this SA accumulation. SA exerts this germination-promoting function by inducing indole-acetic acid (IAA) catabolism through the IAA-amino acid conjugating enzyme GH3. The metabolic cascade we identified may potentially be adopted in agriculture to improve the underwater germination of submergence-intolerant rice varieties. SA pretreatment is also a promising strategy to improve submerged rice germination in the field.

Carcinine, a valuable imidazole dipeptide with antioxidant and therapeutic properties, faces biosynthesis challenges due to enzyme aggregation and substrate inhibition. In this study, an integrated strategy combining linker peptide engineering and immobilization was applied to address these challenges and enhance carcinine production. Rational design of linker peptides (D 5 , L 2 , L 3 ) in the sfp-Ebony fusion protein enabled its highest soluble expression in WSL 2 E strain, achieving 93.1% conversion efficiency—3.5-fold higher catalytic efficiency than WSGE strain. Response surface methodology optimized sodium alginate-polyvinyl alcohol (SA-PVA) immobilization parameters (5% PVA, 3% SA, 2.3% CaCl₂), yielding excellent immobilized WSL 2 E@SA-PVA cells with 95.93% activity recovery. Structural characterization by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) confirmed the formation of a porous SA-PVA matrix that protected cells from harsh conditions. The immobilized biocatalyst exhibited superior operational stability (retaining > 80% activity after 7 cycles) and storage stability (maintaining 44.89% activity after 14 days at 4°C). Fed-batch scale-up (50 mL) achieved a record carcinine titer of 71.13 mM, mitigating the inhibitory effect of high substrate concentrations through phased substrate feeding. This study provides a scalable biocatalytic platform for industrial carcinine production, effectively addressing key bottlenecks in biocatalyst stability and substrate tolerance.

Hydrogel-based wearable devices have attracted tremendous interest in health monitoring, the development of more compatible, effective, and stable sensing material is one of the most daunting challenges. In this work, the poly (vinyl alcohol)/sodium alginate/carbon nanotubes (PVA/SA/CNT) composite hydrogel was prepared, with the formation of PVA/SA double crosslinking network and hydrogen bonds between CNT and PVA. The synergistic enhancement effect of SA and CNT on the PVA hydrogel has been investigated systematically, and the hydrogel with PVA:SA ratio of 9:1 and CNT concentration of 5 mg/mL exhibit optimal comprehensive performance, characterized with high stretchability (∼346 %), good elastic recovery, and anti-fatigue stability over 1000 cycles at 30 % strain. The optimal PVA/SA/CNT hydrogel was applied as the strain sensor for human motion demonstrating sensitive response not only to tiny deformations (such as facial muscle contractions and throat swallowing motions), but to large-range joint flexions (such as finger, wrist and knee), with a low detection limit even under a very slight strain of 0.4 %. Besides, compared to the commercial dry electrodes, the hydrogel skin-like electrodes achieved a significantly elevated signal-to-noise ratio (SNR) from 7.5 dB to 18.2 dB for the electrocardiography monitoring. The study provides new insights into structural design strategies for flexible sensing materials and wearable device.

The widespread use of sulfamethoxazole (SMX) has raised significant concerns regarding environmental residue pollution and the emergence of bacterial antibiotic resistance. Anaerobes play crucial roles in the biogeochemical element cycle and the degradation of organic pollutants; however, the pure-cultured anaerobes involved in SMX anaerobic degradation and their underlying mechanisms remain largely unknown. In this study, a novel anaerobic bacterium, Cupidesulfovibrio sp. strain SA-9, was isolated and characterized for its ability to degrade SMX. Strain SA-9 preferentially utilized lactate or pyruvate as electron donors and sulfate, nitrate, or carbonate as electron acceptors to drive SMX degradation. The degradation T 1/2 values of SMX at concentrations ranging from 10 to 800 μM were between 6.0 and 17.2 d under optimal conditions which included pH 7.0-8.0, 30–37°C, sulfate as the electron acceptor, and pyruvate as the electron donor. Strain SA-9 degraded SMX via isoxazole ring cleavage, acetylation, and hydroxylation, and the ECOSAR-predicted results and bacterial growth inhibition assays indicated that these pathways was detoxifying. Multi-omics analysis and heterologous expression revealed that strain SA-9 degraded SMX via a reductive transformation pathway fueled by electron donors oxidized through the TCA cycle, with electrons transferred through a chain involving flavin-dependent thymidylate synthase (FDTS) and ferredoxin (Fd) to reduce electron acceptors that provide reducing power for SMX degradation. Furthermore, the degradation half-life ( T 1/2 ) values of SMX at 10 and 50 μM were 1.7 and 1.8 d in actual wastewater. Strain SA-9 significantly enhanced SMX removal and mitigated the dissemination risk of ARGs sul1 and sul2 in actual wastewater. This study elucidates the anaerobic microbial resistance mechanism to SMX and highlights the potential of strain SA-9 for the bioremediation of SMX-contaminated water.

A single-atom alloy with isolated Os in NiCu was constructed. • Os promotes water dissociation on Ni sites and optimizes hydrogen binding. • Reconfiguration of interfacial water yields a free-water-rich environment. • The catalyst delivers excellent performance and durability in an AEMWE device. Developing efficient and durable alkaline hydrogen evolution reaction (HER) catalysts is essential for sustainable hydrogen production via anion-exchange membrane water electrolysis (AEMWE) yet remains challenging. Herein, we report a single-atom alloy catalyst comprising atomically dispersed Os on the NiCu alloy array support (Os SA/NiCu), where the unique coordination environment engenders strong electronic interactions that synergistically enhance catalytic activity. The optimized catalyst achieves an overpotential of only 14 mV at 10 mA cm −2 and operates stably for over 2000 h at 200 mA cm −2 . Combined in situ spectroscopy and theoretical calculations reveal that the Os incorporation facilitates water dissociation on adjacent Ni sites, optimizes hydrogen binding energetics, and reconstructs the local interfacial water structure, thereby accelerating alkaline HER kinetics. When employed as the cathode in an AEMWE device, Os SA/NiCu delivers a cell voltage of 1.76 V at an industrial-relevant current density of 1 A cm −2 at 80 °C, with exceptional stability exceeding 500 h. This work establishes single-atom alloy engineering as an effective strategy to enhance noble metal utilization and intrinsic activity toward durable AEMWE systems. A single-atom alloy catalyst comprising atomically dispersed Os on a NiCu alloy array support was synthesized. In situ spectroscopy and DFT reveal that Os incorporation accelerates alkaline HER by synergistically modulating water dissociation, hydrogen binding, and interfacial water structure. Consequently, the catalyst achieves 1 A cm −2 at 1.76 V and operates stably at 0.5 A cm −2 for 1000 h in an AEMWE device. Download: Download high-res image (127KB) Download: Download full-size image

Bacterial infection and persistent local inflammation severely hinder the healing of bone defects, and conventional bone repair materials fail to achieve antibacterial treatment and bone regeneration regulation at the same time. As mechanical cues can modulate cell behaviors and osteogenesis, piezoelectric materials can convert ultrasound stimulation into bioelectrical signals and reactive oxygen species for bacteriostasis and osteogenic regulation. In this work, we prepared a composite hydrogel by incorporating strontium titanate into crosslinked sodium alginate/ε-polylysine networks. This material exhibits obvious pH-responsive release in acidic inflammatory microenvironments and realizes highly efficient sterilization under ultrasonic assistance. In vitro experiments confirm its outstanding biocompatibility. It effectively regulates macrophage polarization to relieve inflammatory responses and greatly promotes the osteogenic differentiation of bone marrow mesenchymal stem cells. This study establishes a feasible fabrication strategy for multifunctional therapeutic hydrogels and provides a promising platform for the comprehensive treatment of clinically infected bone defects.

Conventional ureteral stents frequently cause mucosal damage during placement due to surface hydrophobicity and elevated friction coefficients. Additionally, post-insertion complications such as bacterial adhesion and calculus deposition pose significant clinical risks. To address these challenges, we developed a polyacrylamide/sodium alginate-Ca 2+ (PAAm/SA-Ca 2+ ) dual-network hydrogel as a functional coating for ureteral stents. By modulating calcium chloride (CaCl 2 ) concentration, we optimized the PAAm/SA-Ca 2+ dual-network hydrogel's cross-linking density, resulting in enhanced hydrophilicity, reduced swelling ratio (from 48.5% to 17.3%), and a lower coefficient of friction (COF) (from 0.19 to 0.06). The hydrogel coating exhibited excellent stability and sustained lubricity with a uniform thickness of approximately 16 μm. Notably, the coating reduced calculus deposition by 74% over a 7-day period and demonstrated exceptional antibacterial efficacy, achieving 97% inhibition against Escherichia coli ( E. coli ) and 98% against Staphylococcus aureus ( S. aureus ). Furthermore, the coating displayed favorable hemocompatibility. These findings highlight the potential of PAAm/SA-Ca 2+ dual-network hydrogel coatings for improving ureteral stent performance.

Photothermal 3D hydrogels have shown great potential for solar-driven desalination. In this study, an integrated 3D photothermal hydrogel evaporator was developed to enhance evaporation performance by leveraging a solar-induced environmental heat field and a concave evaporation surface. The photothermal hydrogel matrix was fabricated by incorporating sodium humate-based photothermal particles (synthesized through the chelation of sodium humate and Cu 2+ ) into a sodium alginate/polyacrylamide hydrogel network. The resulting 3D hydrogel evaporator, featuring a tree-ring structure, achieved a stable evaporation rate of 2.23 kg m −2 h −1 in deionized water for 3 h under one-sun irradiation and demonstrated robust performance in various water bodies, including strong brine and sewage. To further enhance energy input, a commercial photothermal enclosure was integrated to create a surrounding heat field under sunlight. By combining energy from the photothermal particles and the solar-induced heat field, the evaporator with a concave evaporation surface achieved an exceptional evaporation rate of 3.69 kg m −2 h −1 under one-sun irradiation, corresponding to a theoretical solar energy utilization efficiency of 193 %, representing a 65 % improvement compared to pre-integration levels. This work presents a novel strategy for designing high-efficiency solar evaporators, offering significant advancements in sustainable desalination technologies.

Fenton reaction is a traditional advanced oxidation process that has long been used for wastewater treatment. However, the narrow pH range of 2–4, the inefficient utilization of both H 2 O 2 and Fe 2+ , and the large amount of iron sludge formation limit its application. Here, we prepared sodium alginate composite hydrogel spheres with both Fe 2+ and CoS 2 loading (denoted as CoS 2 /Fe/SA hydrogel spheres) to construct a CoS 2 /Fe/SA + H 2 O 2 reaction system. The degradation efficiency of carbamazepine (CBZ) in the CoS 2 /Fe/SA + H 2 O 2 system was significantly enhanced with a first-order kinetic reaction constant of 0.1958 min −1 , which is 8.9 times higher than that in Fe 2+ +H 2 O 2 system. When the initial solution pH was in the range of 2–8, the removal rate of CBZ at 90 min reaction time ranged from 96.5 % to 99.9 %. The enhanced degradation efficiency even in a slightly alkaline aqueous solution was due to the sustained slow release of Fe 2+ from the CoS 2 /Fe/SA hydrogel spheres that enhances the utilization of Fe 2+ and the promotion of Fe 3+ /Fe 2+ cycling via CoS 2 . Moreover, the release amount of Fe 2+ in CoS 2 /Fe/SA hydrogel spheres could be controlled by tuning the Fe 2+ loading amount during preparation, which in turn determines its number of cycling uses.

The escalating global freshwater crisis demands urgent development of high-performance desalination technologies. Solar-driven interfacial evaporation (SIE) has emerged as an energy-efficient and environmentally sustainable technology for seawater purification, yet its practical adoption remains hindered by persistent challenges: performance degradation under prolonged operation, and inherent discontinuity of solar energy day and night. Herein, we propose a novel all-day solar-driven interfacial evaporators by solar-thermoelectric cogeneration system, which synergistically integrates a magnetically responsive Janus CS@Fe₃O₄/SA-MF evaporator with thermoelectric generator (TEG) and solar cells. The Janus evaporator fabricated by a facile two-step dip-coating methodology, features engineered asymmetric wettability (contact angle contrast: 152.5° vs. 0°) and exceptional broadband absorption (>99% across 250–2500 nm). Under solar irradiation (1 sun), the system achieved an exceptional evaporation rate of 2.678 kg·m⁻²·h⁻¹ over 10 hours with 96% efficiency, while simultaneously generating electricity according to the Seebeck effect (maximum output: 116 mV, 6.32 mA). Remarkably, due to the Peltier effect, the energy storage of the solar cell enabled sustained nocturnal operation, maintaining an evaporation rate of 1.088 kg·m⁻²·h⁻¹ (7 times of pure water). The synergistic design utilizes solar evaporation during the day and energy conversion at night to effectively overcome the barrier of dependence on sunlight. This work proposed cogeneration strategy opens new avenues for sustainable freshwater production and decentralized energy supply in water-energy nexus applications.

In this work, we proposed a self-assembly method to fabricate a novel pervaporative membrane for desalination. The graphene oxide (GO) layer was deposited on polyacrylonitrile (PAN) ultrafiltration membrane support by vacuum assistance, and then a thin cross-linked sodium alginate (SA) layer was coated on the GO/PAN membrane surface to form a sandwich-like SA–GO/PAN composite membrane. The morphology and physicochemical structure of the composite membrane were characterized using attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), scanning electronic microscopy (SEM), and atomic force microscopy (AFM) techniques and contact angle measurement. The thin SA layer would stabilize and protect the structure of GO layer of SA–GO/PAN membrane, thus GO layer was not easy to fall off or crack during pervaporation desalination. The effects of SA coating concentration, feed temperature, salt concentration, and multicomponent salt solutions on the desalination performance of the prepared membrane were investigated. SA–GO/PAN membrane showed a good desalination performance for high salt concentration solutions and multicomponent salt solutions. When the feed temperature raised from 30 to 80 °C, the flux of the SA–GO/PAN composite membrane increased from 5.61 to 18.35 kg m −2 h −1 , while the rejection still remained above 99.8%. The experimental results showed that SA–GO/PAN composite membrane performed well in pervaporative desalination of salt solution with excellent long-term stability. Graphical abstract
