Glycosylation enhanced EWP emulsifying capacity for stable HIPEs. • HIPEs formed jammed droplet networks with viscoelastic behavior. • Interfacial adsorption governed droplet size and microstructure. • Dense interfacial layers improved β-carotene stability (>90%). • Optimal conjugate level (1.5%) maximized bioavailability (+146%). High internal phase emulsions (HIPEs) are promising carriers for lipophilic bioactives; however, their structural stability and digestive performance are highly dependent on interfacial design. In this study, egg white protein (EWP)–xylan oligosaccharide (XOS) maillard conjugates were used to fabricate food-grade HIPEs, and their effects on interfacial adsorption, microstructure, rheological behavior, and delivery functionality were systematically investigated. Glycosylation significantly improved the emulsifying performance of EWP, enabling the formation of stable HIPEs with a maximum oil phase fraction ( ϕ ) of 0.87 at 2.0% conjugate concentration, while a minimum concentration of 0.4% was sufficient at ϕ = 0.80. Increasing conjugate concentration enhanced interfacial adsorption, reduced droplet size, and promoted the formation of a densely packed, jammed droplet network, resulting in concentration-dependent viscoelastic properties. Furthermore, HIPEs effectively improved the thermal and storage stability of β-carotene, with retention exceeding 90% after 30 days, which was attributed to the formation of a dense interfacial barrier that limited mass transfer. In vitro digestion revealed that lipid hydrolysis and β-carotene bioaccessibility were maximized at 1.5% conjugate concentration, reflecting a balance between structural stability and enzymatic accessibility. Overall, this study establishes a structure–function relationship in EWP–XOS-stabilized HIPEs and provides mechanistic insights for designing protein–polysaccharide-based delivery systems for lipophilic bioactive.

The design of coatings that simultaneously exhibit high thermal conductivity and superior corrosion protection performance in extreme corrosive environments has garnered considerable interest in the academic community. However, constructing a continuous phonon conduction pathway within the coatings is extremely challenging. Inspired by the urchin structure, we developed a carbon-based three-dimensional thermally conductive network filler with the urchin-like morphology through a combination of in situ liquid-phase compounding, high-temperature pyrolysis, and self-assembly. This unique three-dimensional interconnected architecture enables continuous phonon conduction pathways that facilitate efficient thermal conduction while simultaneously reinforcing the “labyrinth” effect to suppress corrosive media permeation, thereby overcoming the intrinsic trade-off between thermal conductivity and corrosion protection. The as-prepared composite coating with a filler loading of 10 wt% delivers a 286% enhancement in thermal conductivity compared to the blank novolac epoxy (EPN) coating, while maintaining outstanding corrosion protection performance under harsh corrosive conditions. This research presents a unique method for designing and preparing composite coatings with high thermal conductivity and corrosion protection performance, thereby exhibiting significant potential for waste heat and water vapor recovery.

Developing cost-effective bifunctional electrocatalysts for oxygen reduction and evolution reactions (ORR/OER) is crucial for rechargeable Zn-air batteries. Herein, we synthesize a novel catalyst comprising helical carbonaceous nanotubes encapsulating cobalt nanoparticles, using corn stigma agricultural waste, melamine and cobalt chloride as precursors. The curved surface of helical carbonaceous nanotubes promotes metal ion dispersion and charge separation within the carbon lattice. Applying strain engineering to these curved structures further tunes the electronic configuration of the active centers, boosting electrocatalytic performance. The as-prepared catalyst demonstrates remarkable electrocatalytic performance, achieving a high ORR half-wave potential of 0.869 V with minimal degradation (10 mV shift after 5000 CV cycles), along with a low OER overpotential of 350 mV at 10 mA cm −2 . In liquid Zn-air batteries, the catalyst delivers a peak power density of 214.8 mW cm −2 and stable operation for over 390 h at 10 mA cm −2 with negligible voltage decay. Moreover, the corresponding flexible wearable Zn-air battery demonstrates excellent foldability and cyclic stability. These results highlight a promising strategy for designing durable, high-efficiency electrocatalysts for metal-air energy systems.

Electrocatalytic CO 2 reduction reaction (ECO 2 RR) faces limitations in conventional reactors due to high energy consumption, inefficient mass transport, and poor durability caused by ion-exchange membranes. Herein, we developed a membrane-free flow electrolyzer that dynamically decouples cathodic CO 2 -to-CO reduction from the anodic oxygen evolution reaction via a regenerative bromide cycle (Br − /BrO 3 − ). Operating at 216 mA cm −2 , the system achieves a record-low cell voltage of 1.85 V, maintains over 99% CO Faradaic efficiency, attains 32.9% single-pass CO 2 conversion, and reaches 71.9% energy efficiency (EE), with negligible degradation over 100 h of continuous operation. Operando spectroscopy reveals that local pH stabilization at 7.2 optimizes *CO/*H adsorption, thereby enhancing CO selectivity and EE. Techno-economic analysis shows a 60% lower power cost (111.8 vs. 277.79 $ ton −1 CO) vs. conventional systems. This work provides new insights into addressing persistent challenges in ECO 2 RR, including mass transfer limitations, carbonate formation, and anodic reaction mismatch.

The proliferation of wireless technologies has rendered electromagnetic wave pollution a critical concern, driving the demand for lightweight absorbers with broad bandwidth and strong attenuation. However, achieving a balance between impedance matching and loss capacity remains challenging, especially at low filler loadings. Herein, a multi-interface engineering strategy is reported to construct an ultralight hierarchical carbon foam decorated with bimetallic selenides (CoSe 2 /MnSe/C@MC, denoted CMCM). This architecture is fabricated via in-situ growth of bimetallic CoMn-ZIFs on carboxymethyl cellulose-modified melamine foam, followed by carbonization and selenization. The three-dimensional porous framework provides excellent impedance matching and multiple scattering, while the synergistic effects of interfacial polarization, dipolar polarization, and conductive loss enhance microwave attenuation. The optimized foam achieves a minimum reflection loss of −63.91 dB at a thickness of 1.43 mm and an effective absorption bandwidth of 4.72 GHz at 1.41 mm. Additionally, the lightweight foam exhibits favorable thermal insulation capability. This work establishes a versatile multi-interface engineering paradigm for designing lightweight, broadband, and multifunctional electromagnetic wave absorbers.

Developing microwave absorbers that simultaneously achieve high absorption efficiency and improved corrosion resistance remains challenging, particularly under corrosive environments containing chloride ions. Herein, we designed a multilayered FI@SiO 2 @TiO 2 composite using flake carbonyl iron (FI) as the core and a sol-gel strategy based on heterointerface engineering. Electrochemical measurements reveal that the corrosion rate of FI@SiO 2 @TiO 2 is nearly two orders of magnitude lower than that of pristine FI, reaching as low as 0.012 mm/year. This enhanced corrosion resistance mainly arises from the dense and chemically inert SiO 2 @TiO 2 dual-shell structure, which effectively suppresses the diffusion of corrosive species and inhibits electrochemical reactions at the metal surface. Electromagnetic characterization shows that FI@SiO 2 @TiO 2 achieves a minimum reflection loss (RL min ) of −65.01 dB at 4.18 GHz with a thickness of 2.23 mm, along with a maximum effective absorption bandwidth (EAB) of 4.53 GHz at only 1.36 mm. Such excellent performance predominantly originates from engineered heterogeneous interfaces, which induce abundant interfacial and dipolar polarization and markedly improve impedance matching of the flake iron core. Furthermore, electromagnetic simulations based on COMSOL and CST corroborate the positive role of the dual-shell architecture in optimizing impedance matching and reducing radar reflection. This work offers a practical strategy for fabricating dual-functional microwave absorbers capable of delivering high absorption efficiency together with sustained corrosion resistance.

Novel Yb-BiOI/Ce-MgAl-LDH S-scheme heterojunction boosts photo-Fenton degradation. • Substrate molecular orbitals govern the selective 1 O 2 -dominated degradation. • S-scheme heterojunction achieves 100% TC-HCl degradation within 20 min. • The system demonstrates excellent environmental adaptability and stability. • Photocatalytic mechanism elucidated via experiments and DFT calculations. Developing highly selective catalytic systems remains a grand challenge in advanced water remediation. A novel S-scheme Yb-BiOI/Ce-MgAl-LDH heterojunction was rationally designed to synergistically boost photo-Fenton degradation via targeted singlet oxygen ( 1 O 2 ) generation. Unambiguously validated by in situ XPS and density functional theory (DFT) calculations, the S-scheme charge-transfer pathway efficiently accelerated spatial carrier separation while preserving maximum redox potentials. Consequently, the composite rapidly degraded the parent tetracycline hydrochloride within 20 min and achieved a mineralization efficiency of 52.5%, exhibiting outstanding degradation performance. Crucially, mechanism studies and density functional theory analyses have demonstrated that this highly selective reaction process, driven primarily by 1 O 2 as the dominant reactive oxygen species, is essentially determined by the energy levels of the specific molecular orbitals of the substrate. Pathway elucidation, coupled with in silico predictions and empirical phytotoxicity bioassays, comprehensively confirmed the substantial reduction in intermediate ecotoxicity. Ultimately, the scientific value of this work lies in providing deep mechanistic insights into S-scheme-driven selective oxidation, offering a robust and sustainable paradigm for designing targeted detoxification systems in wastewater treatment.

A dual-ion (H + /Cl − ) electrochemical polarization strategy dynamically tunes EMW shielding in flexible CNTs@PANI composites. • Dual-ion intercalation restructures PANI to optimize its band gap, sheet resistance, and reflective EMW shielding. • Uneven ion accumulation enlarges dipole moment and dielectric constant, significantly boosting EMW absorption shielding efficiency. • Synergistic reflection-absorption modulation achieves an ultrahigh specific shielding effectiveness variation of 289.44 dB·mm −1 . • A flexible sandwich device offers tunable X-band EMW shielding (26.29–42.06 dB) and robust bending/cycling stability. Dynamic manipulation of electromagnetic waves (EMWs) represents an indispensable cornerstone for next-generation intelligent stealth and adaptive communication systems. Nevertheless, the practical implementation of state-of-the-art electromagnetic materials remains severely constrained by insufficient modulation capabilities arising from single regulatory mechanisms, along with compromised operational flexibility and reliability. Herein, we report a dual-ion-mediated electrochemical polarization strategy in a flexible carbon nanotube@polyaniline (CNTs@PANI)-based device, which enables precise dynamic regulation of EMWs via the synergistic modulation of electromagnetic reflection and absorption. In-situ structural characterizations coupled with theoretical simulations demonstrate that electric-field-triggered H + /Cl − dual-ion intercalation drives the structural rearrangement of PANI from a non-polarized quinoid state to a polarized benzenoid structure. This transformation increases the content of protonated imine groups from 33.01% to 60.97%, narrows the band gap from 2.62 eV to 0.99 eV, and lowers the sheet resistance by 82.4% (from 47.99 to 8.43 Ω·sq. −1 ), thereby tailoring the EMW reflection shielding effectiveness (SE R ) from 4.71 dB to 8.84 dB. Furthermore, the asymmetric electrostatic potential distribution induced by H + /Cl − dual-ion intercalation and accumulation in PANI backbone amplifies the dipole moment by 118% (from 4.02 to 8.77 Debye), generating a pronounced dielectric polarization effect accompanied by maximum enhancement ratios of 172% and 6300% for the real (ε’) and imaginary (ε”) parts of the permittivity, respectively, which boosts the absorption shielding effectiveness (SE A ) from 11.12 to 17.75 dB. Consequently, the synergistic modulation of reflection and absorption contributes to thickness-normalized specific shielding effectiveness variation amplitude (ΔSSE) of 289.44 dB·mm −1 for the CNTs@PANI within the X-band (8.2–12.4 GHz), surpassing previously reported systems. This work establishes a novel paradigm for designing high-performance adaptive EMW protection systems through dual-ion electrochemical engineering.

Formaldehyde as a common indoor volatile organic compound (VOC) poses serious health risks to humans. Therefore, developing efficient formaldehyde adsorbents is essential for improving indoor air quality. Recently, zeolitic imidazolate framework (ZIF)-based adsorbents have attracted significant attention due to their high efficiency in formaldehyde removal. In this work, cellulose nanofiber (CNF) was used as biomass templates to in situ grow ZIF-8, forming a ZIF-8@CNF filter with enhanced adsorption capacity. The physical–chemical properties of ZIF-8@CNF were investigated using SEM, XRD, FTIR and XPS. The results demonstrate that the successful self-assembly of ZIF-8 crystals onto CNF results in a ZIF-8@CNF filter with a high specific surface area and abundant pore structures. Meanwhile, the ZIF-8@CNF filter demonstrated remarkable formaldehyde adsorption capacity, and achieved 88.32% removal of formaldehyde within 6 h. Additionally, the filter maintains stable structural integrity while retaining over 70% of the formaldehyde adsorption capacity after undergoing five adsorption–desorption cycles, demonstrating outstanding reusability. Furthermore, the adsorption of formaldehyde by the ZIF-8@CNF filter relies on its internal layered porous structure and noncovalent interactions with formaldehyde molecules. Therefore, the as-prepared ZIF-8@CNF filter offers an effective solution for indoor formaldehyde removal.

Background This study was designed to investigate the underlying mechanisms of Tanshinone ⅡA using an in vitro model of lipopolysaccharide (LPS)-induced human periodontal ligament fibroblasts (HPDLFs). Methods An LPS-induced periodontitis model was constructed with HPDLFs. Cell counting kit-8 (CCK-8) and flow cytometry assays were used to assess cell viability and apoptosis of model HPDLFs. The content of inflammation-relevant cytokines was quantified by ELISA, and the autophagosome formation was observed under a transmission electron microscopy. Further, correlations with mediators related to autophagy and protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway were tested via quantitative PCR and immunoblotting assays. For validation, rescue assays were performed using autophagy inhibitor 3-MA or AKT activator SC79. Results Tanshinone ⅡA effectively restored cell viability, inhibited apoptosis, and significantly downregulated the expression of inflammatory cytokines TNF-α, IL-6, IL-8, and IL-1β. Tanshinone IIA promoted autophagosome formation, upregulated the expression of Beclin 1, downregulated p62 levels, and simultaneously inhibited the phosphorylation of the AKT/mTOR signaling pathway. Intervention experiments using the autophagy inhibitor 3-MA and the AKT activator SC79 confirmed that the protective effects of Tanshinone IIA was dependent on the activation of autophagy and inhibition of the AKT/mTOR pathway. This study is limited to in vitro assays in LPS-induced HPDLFs, and lacks in vivo validation. Conclusion This study further evaluated the anti-inflammatory property of Tanshinone ⅡA on LPS-induced HPDLFs, and proposed that the activation of autophagy and suppression of AKT/mTOR pathway may account for such effects.

Background Embedding carbon dots (CDs) within protective matrices to preserve their room-temperature phosphorescence (RTP) has enabled the development of autofluorescence-free biosensing platforms based on CDs. However, current matrices are inherently inert, which inevitably restricts the bioresponsiveness and signal transduction of CDs in biosensing. Moreover, many matrix-encapsulated RTP-CDs suffer from poorly controlled particle sizes, impairing their biomedical applications. There is an urgent need to develop stimuli-responsive and size-controllable RTP-CDs to unlock their full biomedical application potential. Results We report a universal strategy for fabricating acid-responsive and size-tunable RTP-CDs with integrated diagnostic and therapeutic functions. Specifically, levofloxacin-derived CDs were synthesized and subsequently encapsulated within CaCO 3 microparticles. The as-designed CDs@CaCO 3 exhibit intense aqueous RTP with a lifetime up to 383.9 ms. The particle size and RTP color of CDs@CaCO 3 can be rationally modulated. CDs@CaCO 3 exhibits a rapid and sensitive response to acidic microenvironments. Furthermore, it offers a linear response over a proton concentration range of 0.1-1.0 mM and excellent selectivity. In S. aureus -infected skin wounds, the CaCO 3 matrix undergoes site-specific degradation in response to the acidic microenvironment and leads to significant attenuation of the RTP signal, enabling autofluorescence-free imaging of bacterial infections. Concurrently, the released levofloxacin-derived CDs effectively eradicate bacteria in wounds and accelerate wound healing within 8 days. Significance This study establishes a generalizable paradigm for constructing disease microenvironment-responsive RTP-CDs with tunable physicochemical and optical properties, which is expected to significantly advance the applications of CDs in the diagnosis and treatment of diverse acidic pathology-associated diseases, including bacterial infections, tumors, and atherosclerosis.

Influenza is currently one of the most prevalent respiratory diseases in humans, with outbreaks typically occurring during the winter months. Its impact is particularly pronounced among vulnerable populations, such as the elderly, infants, and individuals with chronic illnesses. Common methods including reverse transcription polymerase chain reaction (RT-PCR), rapid influenza diagnostic tests (RIDTs), and direct fluorescent antibody (DFA) assays for detecting influenza viruses have their own limitations and struggle to meet the point-of-care testing (POCT) demands during influenza pandemics. In this study, a surface-enhanced Raman spectroscopy (SERS) sensor chip based on the immunosandwich principle was developed for the rapid detection of influenza A and B viruses. Using a portable Raman spectrometer, viral antigen detection can be completed within 20 min, with a detection limit as low as 0.69 ng/mL. This provides a new approach for the rapid screening and dynamic monitoring of influenza viruses.
