To address water scarcity in arid regions, this study proposes a high-efficiency fog harvesting material development strategy based on wettability gradient regulation. Controllable assembly of polyvinyl chloride nanofibers with bead-on-string structures on hydrophilic substrate surfaces is achieved through a 5 min electrospinning process. The fabricated Janus membrane achieves a contact angle differential of 141°, establishing an asymmetric wetting structure that enables directional droplet transport. Experimental data show that its fog water collection flux is 2.1 times higher than those of traditional hydrophilic materials. Surface water droplets were absorbed by the Janus membrane in only 2 ms, while they were absorbed by the hydrophilic membrane in at least 5 ms. Moreover, after the water droplets were absorbed, the Janus membrane surface can remain in a fresh, dry state, which is conducive to further water absorption. The underlying mechanisms for the enhanced fog harvesting performance were detailed, with numerical simulations used to study the impact of the hydrophilic layer’s wettability on liquid penetration. Such a Janus membrane can be a promising candidate for fog harvesting against the water crisis.

The electrospun polyvinylidene fluoride (PVDF) based modified boron nitride (m-BN) composite with high thermal conductivity and flexible mechanical property was successfully fabricated by electrospinning method . The uniform dispersion and ordered orientation of m-BN in the m-BN/PVDF composites form a hot string, denoted as a series of thermal conduction fillers, in the direction of the fiber. Hence, the thermal conductivity of the m-BN/PVDF film could reach to 7.29 W m −1 K −1 with the addition of 30 wt% m-BN. Besides, the obtained composites also show improved mechanical properties with the tensile strength of 24.06 MPa, low dielectric permittivity of 2.45 and dielectric loss of 0.0242 @ 10 3 Hz. Therefore, this work provides a new route to prepare the high thermal conductivity films with potential application as flexible power devices.

In view of the poor electronic conductivity and inferior structural stability, the direct application of Metal-Organic Frameworks (MOFs) as an electrode material is limited. Herein, the carboxylated multi-wall carbon nanotubes (MWCNT) are utilized as a substrate for the in-situ growth of bimetallic NiCo-based MOFs (NiCo-MOF). The flower-string-like NiCo-MOF/MWCNT composites are successfully synthesized using 4, 4′-biphenyldicarboxylic acid (BPDC) as a ligand via a simple solvothermal approach. In the composites, MWCNT is wrapped with 2D NiCo-MOF nanosheets through some bonds or affinity between MWCNT and NiCo-MOF. Meanwhile, the MWCNT presence does not affect the formation of the NiCo-MOF crystals. Compared with the hydrangea-like NiCo-MOF microspheres , the flower-string-like composite structures are more loosely assembled by NiCo-MOF nanosheets. Owing to the guiding effect of MWCNT on the NiCo-MOF growth, many well-dispersed flower-string-like structures can be achieved by adjusting MWCNT dosages. Due to the unique hierarchical structure and good synergistic effect, the NiCo-MOF/MWCNT composites exhibit excellent capacitance performances. The optimal composites demonstrate a large specific capacitance of 1010 F g −1 at 0.5 A g −1 , a good rate capability (760 F g −1 even at 10 A g −1 ), a good cycling stability and reversibility with the capacitance retention of 828 F g −1 (100% of the initial capacitance) and coulombic efficiency of approximate 98% at 5 A g −1 after 3000 cycles, a low internal resistance and charge transfer resistance. The asymmetric supercapacitor assembled by NiCo-MOF/MWCNT composites as electrode materials has high energy density even at high power density, good rate capability, excellent cycling stability and reversibility. Hence, the as-synthesized NiCo-MOF/MWCNT composites are a promising high-performance electrode material for supercapacitors .

Wearable electrophysiological interfaces demand bioelectrodes that combine low-impedance, stable ion-electron transduction with high mechanical deformability, yet these requirements remain fundamentally incompatible in existing systems. Here, we present a nonpolarizable stretchable dry electrode based on a bead-on-string Ag/AgCl heterostructure, in which AgCl nanoparticles (NPs) are selectively assembled along percolated silver nanowire networks embedded within an elastomer matrix. This architecture spatially decouples Faradaic reaction sites from conductive pathways, constructing abundant, mechanically robust Ag/AgCl heterointerfaces for efficient ion-electron transduction while preserving continuous electron transport under large deformation. By systematically tuning the size of AgCl NPs (50-800 nm), the spatial distribution and interfacial length scale of Faradaic domains are optimized to maximize electrochemical performance. The resulting electrode achieves ultralow interfacial impedance (49 kΩ, 10 Hz), stable electrode potentials, and tolerance to severe mechanical deformation (ε > 370%), with minimal degradation over 500 stretch cycles. It enables low-noise, high-fidelity signal acquisition in the low-frequency regime, effectively suppressing motion artifacts and maintaining stable operation over 120 days of storage in air. When integrated with a spatiotemporal neural network for electrooculography decoding, the system achieves 98% accuracy in hands-free game control, demonstrating a robust paradigm for next-generation wearable bioelectronics.

Uncontrolled hemorrhage is one of the leading causes of traumatic death, while conventional clay hemostats carry insufficient procoagulant activity, poor adhesion, weak anti-dispersion capability, and the potential risk of distal thrombosis. Inspired by nasal cilia particle capture, poly(vinyl alcohol)/quaternized starch (PVA/QSt) nanofibrous membranes with Oriented (NFM O), Oriented bead-on-string (NFM-OB), Non-oriented bead-on-string (NFM-NOB), and Non-oriented (NFM-NO) four different structures, were fabricated by electrospinning in this study. The results showed that the random beaded nanofibrous membrane (NFM-NOB) exhibited the best hemostatic performance. Based on this structure, we then proposed an integrated “structure regulation-component synergy” strategy and fabricated halloysite nanotubes (HNTs)-reinforced PVA/quaternized starch (HPQ) nanofibrous membranes via in situ electrospinning. By regulating the HNTs content, a series of HPQ nanofibrous membranes were prepared. The optimal HPQ-40 achieved rapid hemostasis with an ultra-low particle loss rate of 1.2% ( vs. 68.4% for QuikClot®) and 7.2 g/g blood absorption capacity. It achieved hemostasis through triple synergies: platelet capture by non-oriented, bead-on-string fibers via topological interlocking, rapid plasma absorption/intrinsic pathway activation by the hollow tubular structure of HNTs, and electrostatic erythrocyte aggregation/antibacterial activity by positively charged QSt. In rat liver laceration and femoral artery puncture models, HPQ-40 shortened hemostatic time by 52.9% and 58.9%, and reduced blood loss by 82.1% and 77.6%, respectively, with excellent biocompatibility. This study provides important experimental evidence and a new strategy for the design and developing high-performance biosafe hemostatic materials.

For most external applied antioxidant whitening ingredients, effective stratum corneum breakthrough, epidermal penetration and dermal deposition are necessary premises for inhibition of melanin production and transfer occurring in stratum basale. Herein, xanthan gum was added into vitamin C-containing flexible liposome (Vc-L) suspension. The long polymer chain of xanthan gum string dispersed Vc-L together to gain a lotion (Vc-LX) for external application. In this study, the storage stability experiments demonstrated that the additional xanthan gum could improve the storage stability of Vc liposome suspension. The cumulative in vitro skin penetration and deposition of Vc-LX was found to significantly increase within 24 h in mouse skin, compared with those of the Vc aqueous solution and Vc conventional liposomes treated groups ( *** p < 0.001). Most importantly, in vivo skin whitening experiments gave that Vc-LX has better skin whitening activity (Δ L *) than marketed products (GARNIER® Vc377), Vc flexible liposomes, and Vc conventional liposomes. Moreover, in vitro cytotoxicity experiments and skin irritation experiments demonstrated that Vc-LX has good biosafety. Therefore, this study suggested that Vc-LX may be a promising local skin delivery system for water-soluble antioxidant ingredients.

In this study, poly (ε-caprolactone) (PCL)/zein/Ag nanoparticle (AgNP) fibrous membranes were prepared by ultrasonication-assisted electrospinning. The effects of the AgNP content and ultrasonication time on the membrane morphology, chemical structure, biodegradability, mechanical properties, antibacterial/antiviral activity, and air filtration performance were studied. The best-performing membrane (AgNP content = 1% (w/v), sonication time = 30 min) exhibited a bead-on-string morphology, an air permeability of 93.6 ± 1.5 mm s −1 , and the Escherichia coli and Staphylococcus aureus removal efficiencies of 98.1 ± 1.2% and 97.4 ± 2.5%, respectively. In an experiment with E. coli phage, the above-mentioned membrane exhibited a 97.1 ± 2.1% virus removal efficiency after 60 min. The high performance of this bead-on-string membrane for air filtration was ascribed to the low packing density due to the presence of open interconnected beaded airflow channels and small beads.

Herba Lysimachiae inhibits synovial damage in osteoarthritis via regulating two bio labels (integrin alpha 2b/beta 3). However, the relevant active ingredients are still unknown. Here, the active ingredients of herbal medicines were analyzed based on the liquid chromatography–tandem mass spectrometry technology and public bioinformatics platforms. The liquid chromatography–tandem mass spectrometry technology was used for compound analysis, and public databases (PubChem BioAssay and STRING) were applied to establish the links between herbal compounds and both bio labels, and identify which herbal compounds may regulate these bio labels. Subsequently, the osteoarthritis model was used to confirm the results. Totally, ninety compounds in Herba Lysimachiae were identified based on the liquid chromatography–tandem mass spectrometry technology. Bioinformatics analysis showed that five compounds (myricetin, fisetin, esculetin, 7-hydroxycoumarin-4-acetic acid, and caffeic acid) may synergistically regulate bio labels through 11 targets, which may be the active ingredients of Herba Lysimachiae for osteoarthritis treatment. In the verification experiments, five compounds markedly suppressed the overexpression of bio labels in the synovium of the osteoarthritis model. In conclusion, the present study effectively and rapidly analyzed the active ingredients of Herba Lysimachiae for osteoarthritis treatment.

In this study, radiata pine wood was impregnated with furfuryl alcohol (FA) resin and radially compressed at compression ratios (CRs) of 17%, 33%, and 50%, respectively, to improve the acoustic and viscoelastic performance. The optimum CR was selected by analyzing the properties of FA-densified modified woods with different CRs. The storage modulus and loss factors of the FA-densified modified woods with CRs of 17%, 33%, and 50% were better than those of fretboard wood. The fretboard wood had an extremely high dynamic modulus of elasticity ( D′ \(\ge\) 16.22 GPa) and dynamic shear modulus ( G′ \(\ge\) 2.23 GPa). The D′ and G′ of the FA-densified modified wood with a CR of 50% were 25.44 GPa and 4.08 GPa, respectively, which are better than those of the fretboard wood. The common fretboard wood had a low sound velocity ( υ ), small specific dynamic elastic modulus ( \({E}_{sp}\) ), small sound radiation coefficient ( R ), and low acoustic conversion efficiency ( ACE ), along with a high acoustic impedance ( ω ) and high sound quality factor ( Q −1 ). The values of υ , \({E}_{sp}\) , R , ACE , ω , and Q −1 of the FA-densified modified wood with a CR of 50% were 4563 m/s, 19.9 GPa, 3.49 m 3 Pa −1 s −3 , 253, 5.70 10 6 (Pa s m −1 ), and 13.80 \(\times\) 10 −3 , respectively, meeting the performance requirements for fretboards and demonstrating the potential to replace fretboard wood in fretboard manufacturing. This research promotes the application of a fast-growing plantation wood for the manufacture of musical instruments and provides a good platform for its high-value utilization.

Solar-driven interfacial evaporation offers a viable pathway for alleviating global water shortages. However, a significant challenge arises when the source water contains organic contaminants, as the evaporation process can lead to the enrichment and exacerbation of pollution in the remaining water. Herein, we constructed a flexible bifunctional nanofibrous membrane evaporator featuring a gems-on-string structure, designed to concurrently realize clean water production and source water purification. This was achieved through the uniform decoration of polypyrrole (PPy) nanoparticles onto silica nanofibers, followed by the tactful immobilization of zeolitic imidazolate framework (ZIF-67) polyhedrons on the fibers via a facile hot-pressing approach. The micro-nano hierarchical structure of the gems-on-string fibers enables multiple reflections between adjacent gems, significantly enhancing full-spectrum light absorption (96.3 %) and photothermal conversion. Moreover, the superhydrophilic and hierarchically interconnected channels within the membrane facilitate water transport and evaporation enthalpy diminution. Furthermore, the synergistic effects of localized heat from PPy, and photocatalysis and cobalt sites from ZIF-67 significantly promote the activation of peroxymonosulfate. As a result, the bifunctional evaporator achieves a rapid evaporation rate (2.29 kg m -2 h −1 ) with a remarkable solar-water conversion efficiency (93.2 %) under one sun, outperforming most state-of-art evaporators, while maintaining superior oxytetracycline removal (92.5 %). Significantly, the evaporator delivers a daily freshwater output (5.3 kg m −2 ) when treating complex wastewater/seawater. This study not only presents an efficient strategy for fabricating flexible high-performance photothermal-catalytic membranes, but also provides a sustainable platform for freshwater production and sewage purification.

Due to the insufficient performance, it is still a challenge to combine conventionally synthesized metal-organic framework (MOF-74) with other materials to fabricate composite electrodes for high-performance supercapacitors . Herein, we synthesized a series of NiCo-MOF-74 composite materials with different amounts of polypyrrole nanotubes (T-PPy) denoted as NiCo-MOF-74/T-PPy-m (m = 2.5, 5, 10, 15 and 20) through in situ growth of the bimetallic MOF around the PPy nanotubes by a simple solvothermal method . By comparison, the NiCo-MOF-74(1)/T-PPy-10 composite, with a Ni/Co molar ratio of 1:1 obtained in the presence of 10 mg of T-PPy, possessed the highest specific capacitance of 849 C·g −1 at 1 A·g −1 and excellent cyclic stability with a capacitance retention rate of 90.0% after 10,000 cycles as well as good rate performance. Moreover, the assembled asymmetric supercapacitor respectively using NiCo-MOF-74(1)/T-PPy-10 and active carbon as positive electrode and negative electrode achieved a superior energy density of 58.4 Wh kg −1 at the power density of 747.6 W kg −1 and high cyclic lifespan (91.4% capacitance retention after 10,000 cycles). The mechanism of capacitance increase was studied in detail, influences of metal molar ratios, morphology and addition amounts of PPy on electrochemical performances of the formed composition materials were systematically discussed, and it was found that the interpenetrating network structure assembled by “string of candied haws”-like T-PPy-interweaved NiCo-MOF-74(1) polyhedrons possessed the best capacitive performance for enhanced conductivity of the resulted composite, improved dispersity of the bimetallic MOF and more exposed active sites. And the interwoven structure alleviated the stress change-induced structure or phase variation caused by repeated volumetric swelling and shrinking during charge/discharge cycle and enhanced the rate capability and cycling stability.

As a simple and visually assessable point-of-care testing method, lateral flow assays (LFAs) are widely used for detecting procymidone in vegetable samples. Meanwhile, an increasing number of aptamer-based LFAs are being developed for rapid detection. However, the sensitivity of conventional gold nanoparticles (AuNPs) aptamer-based LFAs is limited, which is a challenge to meet the detection requirements. This study proposed a dual amplification strategy of click chemistry and hybridization chain reaction (HCR) to construct a colorimetric probe to enhance the sensitivity. The nucleic acid nanostructure (HCR-ALK) constructed by HCR was used as a programming template to guide the click chemical reaction to induce the cross-linking of AuNPs-N3 and HCR-ALK to form a uniform and stable ″ballon-string″ colorimetric probe (HCR-AuNPs). This strategy achieved dual-signal amplification. Under optimal conditions, the limit of detection (LOD) of this LFA was 5.4 × 10–2 ng/mL. Compared with the conventional AuNPs aptamer-based LFAs, its LOD had been improved by 13.69-fold, and its color display time had been reduced to one-tenth. In specificity and stability experiments, this LFA showed a satisfactory performance. Moreover, it was successfully applied to the detection of procymidone in vegetable samples, with a recovery rate maintained between 93.44%–104.00%. Thus, this study provides a signal amplification strategy to address the issue of insufficient sensitivity in aptamer-based LFAs. This will offer new insights for the development of aptamer-based LFAs.
