Bidirectional thermoregulation nanofiber yarns were fabricated using conjugate electrospinning and subsequently integrated into camel-cashmere fabric for enhanced thermal management. By incorporating microencapsulated phase-change materials (μPCMs) and optimizing their mass in the spinning solution, we obtained thermoregulation nanofiber yarns with superior thermal energy storage properties and mechanical performance. Optimal results were observed when the additive mass of µPCMs was 7.5 wt%, yielding nanofiber yarns with a latent heat of up to 39.10 J/g, a breaking force of 184.4 cN, and an elongation of 14.7%. The morphology and structure of these yarns were further refined by adjusting the spinning parameters. The optimized yarns were applied to the camel-cashmere fabric followed by an assessment using an infrared thermal imager. The thermoregulation camel-cashmere fabric exhibited slower temperature variations compared to the ordinary fabric, with maximum temperature differentials of 6.3 and 5.7 °C in the heating and cooling scenarios, respectively. The results indicated that the thermoregulation nanofiber yarns endowed the textile with dynamic thermal insulation from phase-change material and promises more intelligently and actively adjusting the temperature of the body microclimate according to the temperature change of the outside.

With the rapid development of home-based digital health monitoring, conventional single-function electrodes have become inadequate to address growing healthcare demands. Simultaneous and accurate acquisition of both electrophysiological signals and temperature is crucial for comprehensive health monitoring and clinical diagnostics. To address this need, we developed a low-cost multifunctional flexible electrode for concurrent body temperature and electrophysiological signal monitoring without cross-interference. The body temperature can be assessed through visual colorimetric evaluation and measured precisely using a custom-developed smartphone application. Characterized by high air permeability, ultra-thin architecture, superior flexibility, antibacterial effect, and strong skin adhesion, our electrode maintains low interfacial impedance for stable, long-term acquisition of high-fidelity physiological signals (e.g., electrocardiography (ECG) and surface electromyography (sEMG)). Furthermore, when integrated with a Raspberry Pi platform and a hybrid convolutional neural network-long short-term memory algorithm, the system achieves intelligent arrhythmia detection with an exceptional accuracy of 99.30%. The novel electrode offers a powerful tool for multifunctional sensing of temperature and physiological electrical signals, creating exciting potential for applications in wearable physiological tracking.

Adiponectin serves as a critical biomarker for metabolic disorders, with its concentration in human plasma providing predictive value for the risk of prediabetes. In this work, we report a rapid and reliable electrochemical immunosensor designed for point-of-care testing of adiponectin. The immunosensor was fabricated using a gold-sputtered silver screen-printed electrode as the substrate, on which sulfhydrylated antibodies were directly immobilized via Au-S covalent bonding. The fabrication process was characterized and optimized using electrochemical impedance spectroscopy and differential pulse voltammetry. Under optimal conditions, the proposed immunosensor exhibited a wide linear range (0.3–15 μg/mL) with a detection limit of 0.15 μg/mL. It also demonstrated excellent reproducibility and high selectivity for adiponectin detection. Additionally, the proposed immunosensor can be fabricated within 1.5 h and enables accurate quantification in human plasma within 15 min. The practical applicability of the sensor was validated through analysis of human plasma samples, and the comparison results with commercial ELISA kit are satisfactory. Graphical abstract

A novel layered cobalt–magnesium double hydroxide composite (L-CMs) was successfully prepared using a simple one-step co-precipitation method. Static adsorption experiments were conducted to examine the removal efficacy of U(VI) from aqueous solutions by the L-CMs and analyze the removal mechanism. L-CMs efficiently removed U(VI) from the aqueous solution under an adsorption time of 60 min, dosage of 0.4 g/L, and pH of 5.5 at room temperature, and the removal efficiency of U(VI) reached 94.59% with an initial U(VI) concentration of 10 mg/L. The adsorption process was fitted to the pseudo-second-order kinetic and Langmuir models, indicating that monolayer chemical adsorption occurred primarily. The maximum adsorption capacity fitted using the Langmuir model was 105.49 mg/g. Thermodynamic analysis revealed that U(VI) adsorption by L-CMs was endothermic. Structural characterization results showed that the primary mechanism involved the complexation of U(VI) by –OH, CO 3 2− and ion exchange by Mg 2+ and the presence of layered Co(OH) 2 in the L-CMs, which potentially facilitated ion exchange. The preparation of the composite materials was simple, and the synergistic effect between the materials enhanced the ion exchange of Mg 2+ in the materials and enriched the content of functional groups, making it a potential candidate for the treatment of uranium-containing wastewater.

Purpose Human umbilical cord mesenchymal stem cell lysates (UCML) have crucial bioactivities, including tissue regeneration, wound healing, and immune regulation, showing great potential for treating eye diseases. This study investigates the therapeutic efficacy of UCML loaded in artificial tears (AT@UCML) on dry eye syndrome (DES) and retinal injury. Methods This study first evaluated the safety, antioxidant properties, and tissue-repairing effects of AT@UCML in disease-relevant ocular cells. Then, we treated DES and ischemia/reperfusion (I/R) retinal injury mouse models by AT@UCML. To assess the effects in DES mice, we measured tear secretion, corneal damage, and goblet cell numbers. For I/R mice, we examined retinal ganglion cell numbers and retinal thickness. Results Experiments showed that AT@UCML reduced oxidative stress and protected ocular cells. In DES mice, it increased tear secretion, repaired corneal damage, and restored goblet cell counts. In I/R mice, it reduced retinal ganglion cell loss and restored retinal thickness. Conclusions AT@UCML effectively treated DES and I/R injuries by protecting key ocular cells. This study expands the application of stem cell therapy in ophthalmology and provides a basis for developing related treatments.

Lead-based multilayer thin film capacitors with excellent energy storage performances have great application potential. However, the effect of stacking patterns on the dielectric behaviors has not been well investigated, especially for the multilayer thin films prepared by chemical solution methods. Here, the relaxor ferroelectric (RFE) (Pb 0.92 La 0.08 )(Zr 0.65 Ti 0.35 )O 3 and antiferroelectric (AFE) (Pb 0.98 La 0.02 )(Zr 0.95 Ti 0.05 )O 3 were chosen to construct diverse multilayer thin film capacitors with different RFE/AFE stacking patterns. Based on their crystal structure, dielectric features, and energy storage behaviors, the effect of stacking orders and AFE phase thicknesses on the capacitor performances were discussed from the perspectives of the positive and negative interface contribution. A superior recoverable energy density of 26.28 J cm −3 was achieved at a breakdown strength of 3.19 MV cm −1 , accompanied with thermal stability up to 170 °C, frequency stability up to 2 kHz, and fatigue endurance after 10 6 charging-discharging cycles. The experimental results and related discussion will support the research and the industrialization of multilayer thin film capacitors.

The development of efficient and cost-effective catalytic systems for antibiotic degradation remains a significant challenge in environmental remediation. Herein, a novel Co/CuFe 2 O 4 composite was synthesized via a sol–gel combustion method to construct a multi-metal synergistic photocatalytic-Fenton-like system for the degradation of oxytetracycline (OTC). Density functional theory (DFT) calculations indicate that the incorporation of Co leads to a more negative material formation energy, suggesting that Co/CuFe 2 O 4 has a more stable electronic structure. This optimized electronic structure enhances the redox cycle (Fe 3+ /Fe 2+ , Cu 2+ /Cu + , and Co 2+ /Co 3+ ), thereby improving the activation efficiency at low concentrations of H 2 O 2 (0.1–6 mmol/L). Under optimal conditions (pH 3, 35 °C, 4 mmol/L H 2 O 2 ), the 13% Co/CuFe 2 O 4 catalyst achieved complete OTC degradation within 60 min, with an 0.1 mmol/L H 2 O 2 utilization rate of 17.81% at neutral pH. Moreover, the catalyst exhibited excellent stability, retaining 87.5% degradation efficiency after five cycles. Radical quenching experiments confirmed that ·OH, h + , and ·O 2 − were the dominant reactive species, while the synergistic effect of multiple metal redox pairs facilitated efficient electron transfer and H 2 O 2 activation. This work provides a promising strategy for designing high-performance Fenton-like catalysts with broad pH adaptability and low oxidant consumption, offering significant potential for the treatment of antibiotic-contaminated wastewater.

Electromagnetic (EM) shielding fabrics offer a promising solution to the growing issue of EM pollution. There is particularly demand for fabrics applicable in complex environments where comfort, durability, and multifunctionality are essential. In this work, we report the design of multifunctional EM shielding fabric (denoted as Silk-Ppy-PDMS) based on natural silk, which achieves self-cleaning, photothermal antibacterial and efficient EM shielding. By in situ polymerization of hydrophilic polypyrrole (Ppy) onto silk and applying superhydrophobic polydimethylsiloxane (PDMS) coating, we imparted multiple functionalities to the fabric. The needle-like Ppy coating introduces surface roughness favorable for superhydrophobicity, enabling effective self-cleaning. Meanwhile, the same structure enhances light absorption and conversion into heat, contributing to strong photothermal antibacterial. In addition, the fabrics complex surface topography not only facilitates the reflection of X-band EM waves but also leverages the dielectric loss of Ppy to effectively absorb incident radiation. Remarkably, the optimal composite, designated as Silk-P5-P, exhibits Stable WCA (155.5°), peak photothermal temperature (68.5 °C), excellent antibacterial rate (99.95%), superior EM shielding effectiveness (26.3 dB) and exceptional EMI SE per unit thickness (202.31 dB mm⁻¹). Collectively, these features establish the Silk-Ppy-PDMS series (specifically, Silk-P5-P) as a next-generation, wearable EM shielding fabric with robust self-cleaning and antimicrobial, offering considerable potential in advanced multifunctional textile applications.

Self-assembled monolayers (SAMs) play an important role in improving the performance of inverted perovskite solar cells. However, loose molecular packing, non-uniform coverage, weak affinity with the solvents of perovskite precursors, and energy-level mismatch cause energy losses at the buried interface. Here we develop a light-stable donor–acceptor interface formed by an asymmetric carbazole-based SAM, namely, BrAs, and N -hydroxyethyl phthalimide (PIE). The single-side electron-withdrawing bromine in BrAs maintains wettability and reduces the valence band offset to 0.09 eV. Additionally, the asymmetric dipole in BrAs reorients the carbazole units and strengthens short-range Coulomb interactions, resulting in close packing and uniform coverage of SAMs for efficient and uniform carrier transport. The donor–acceptor interface also promotes ultrafast energy transfer, which enhances the photostability of BrAs and improves thermal carrier extraction by 19%, further minimizing energy losses. In particular, the lattice-matching PIE molecules stabilize the (100) out-of-plane orientation of the perovskite by interlocking [PbI 6 ] 4⁻ octahedra, which releases compressive stress and stabilizes the buried interface. As a result, BrAs–PIE devices achieve a power conversion efficiency of 27.28% (certified, 27.19%) and retain over 95% of the initial efficiency after 1,500 h of illumination under the ISOS-L-2 protocol.

Striking a balance between sensitivity and detection range while ensuring stability under extreme temperatures remains a formidable challenge in the design of flexible pressure sensors. To address this issue, we draw inspiration from the multi-gradient architectures of nature and propose a bottom-up self-assembly strategy. By leveraging a meticulously orchestrated multi-step approach that encompasses electrospinning, sequential freezing, and thermal imidization, we successfully fabricate a polyimide nanofiber/carbon nanotube dual-gradient aerogel with a dynamic stiffness transition from flexible to rigid states. Experimental results highlight notable properties of the dual-gradient aerogel, which exhibits an ultralow density (0.023 g cm − 3 ), efficient thermal insulation (28 mW m − 1 K − 1 ), and reliable compressibility and fatigue resistance. Moreover, it establishes a favorable equilibrium between sensitivity (156 MPa − 1 ) and an extensive detection range (223 kPa). Notably, the combination of thermal resilience (−196 °C to 533.30 °C) and mechanical stability enables performance that is comparable to, or in some aspects surpasses, that of conventional flexible sensing materials. This dual-gradient aerogel provides both effective thermal insulation and high-precision physiological monitoring under extreme conditions, offering integrated thermal protection and real-time astronaut health assessment in spacesuits.

Thrombotic diseases remain a major global health concern with high morbidity and mortality. Four biomarkers (TAT, t-PAIC, TM, PIC) enable real-time monitoring of coagulation, addressing limitations of traditional diagnostics. Herein, we developed a multiplex electrochemical immunosensor for the simultaneous detection of these biomarkers. The sensing platform is constructed on a glassy carbon electrode modified with gold nanoparticles and laser-induced graphene (AuNPs-LIG), which enhances conductivity and signal output. A “One-for-Four” strategy was employed using four distinct redox probes (AQ, OAP, MB, PPD), each conjugated to a specific antibody via amidation and anchored to functionalized carbon nanotubes (Au@CNTs), forming a multichannel signal amplification system with high sensitivity. The immunosensor exhibited excellent linearity (10–100 ng/mL, R 2 > 0.98) and low detection limits: 3.99 ng/mL (TAT), 5.25 ng/mL (t-PAIC), 2.51 ng/mL (TM), and 4.20 ng/mL (PIC). It also demonstrated high selectivity, reproducibility and long-term stability. Recovery in human plasma ranged from 84.1% to 112.21%, indicating strong applicability to complex clinical samples. This work presents a robust, portable POCT platform with great potential for early diagnosis and dynamic monitoring of thrombotic diseases. Graphical

Developing Earth-abundant anode electrocatalysts for proton-exchange-membrane water electrolysis (PEMWE) to replace iridium is crucial for reducing hydrogen production costs but their poor acid stability remains a major challenge. Here we prepare a lanthanum and calcium co-doped Co 3 O 4 catalyst, which can tune water–surface interactions to suppress cobalt dissolution, thereby enhancing stability. Lanthanum with weak water affinity is introduced onto the Co 3 O 4 surface to construct atomic sites with specific water–molecule interactions (CoLa-SWMI). The CoLa-SWMI reconstructs the interfacial water environment and moderately alleviates the polarization of the metal–oxygen bond induced by hydrogen bonding with water molecules, thereby extending catalyst lifetime. Moreover, the leaching of surface calcium species creates highly active coordinatively unsaturated cobalt sites, which enhance catalytic activity (CoLaCa-SWMI). PEMWE using a CoLaCa-SWMI anode operates stably for 830 h at 1.0 A cm −2 . This study provides an approach to designing non-noble-metal electrocatalysts, potentially reducing reliance on rare metals in PEMWE.
