To overcome the difficulty of forming stable and continuous conductive pathways of MXene in conventional electrospinning systems, we develop a high-performance flexible pressure sensor featuring a synergistic embedded–coated dual conductive architecture. A TPU/PCL nanofiber membrane uniformly incorporating MXene is fabricated via one-step electrospinning, followed by PEDOT:PSS dip-coating to construct an external conductive layer. Subsequent Ecoflex 00–30 encapsulation ensures mechanical integrity and maintains continuous multilevel electron-transport networks. Structural characterizations confirm the homogeneous incorporation of MXene within the nanofibers and the continuous surface coverage of PEDOT:PSS. The optimized sensor exhibits a maximum sensitivity of 7.05 kPa⁻¹ in the low-pressure region, together with a broad sensing range up to 100 kPa, enabling reliable detection across both subtle and high-pressure regimes. It further demonstrates fast dynamic response (0.11 s/0.31 s for response/recovery), a low detection limit of 50 Pa, and excellent durability over 2000 loading cycles. Demonstration tests confirm its ability to detect subtle physiological motions at different body locations, such as wrist movements and throat motions during swallowing, as well as various joint motions. Overall, this synergistic dual conductive strategy offers a promising platform for wearable health monitoring, electronic skins, and human–machine interaction.

The synthesis of novel film-like photocatalysts is an effective strategy for reducing Cr(VI). Herein, a Z-scheme ZnIn 2 S 4 –CdS heterojunction photocatalyst was fabricated on a self-assembled graphene-based substrate via hydrothermal and solvothermal methods. By controlling the ethanol:water ratio during solvothermal synthesis, differently sized CdS nanoparticles were grown on the ZnIn 2 S 4 nanosheets surface for regulating the photocatalytic activity of ZnIn 2 S 4 –CdS heterojunction. The three-dimensional layered structure of the graphene film provided abundant active sites for material loading and its excellent conductivity rapidly transferred photogenerated electrons. Compared to the ZnIn 2 S 4 –CdS heterojunction samples with other controlled structure, graphene-based film-like photocatalyst bring advantage in enrich photocatalysts for bursting out better activity. Under visible light irradiation, the synthesized RZC-40 sample exhibited a photocatalytic efficiency of 91.02% in photoreducing 20 mg L −1 Cr(VI) within 50 min, highlighting the feasibility and promising practical application prospects of synergistic film-like photocatalysts and laying a theoretical foundation for the further development of photocatalysts with improved activity.

Early fault detection of lithium-ion batteries (LIB) is crucial for the safe operation of electrical measurement systems. Detecting the dimethyl carbonate (DMC) vapor in the LIB electrolyte can effectively improve the early warning time. However, the response speed of the existing semiconductor resistive gas sensors is significantly slower compared with the commonly used temperature and pressure sensors. To address the issue within gas sensors, a DMC gas sensor with an extremely fast response speed was developed based on mixed-phase bismuth oxide, which can effectively respond to 20 ppm DMC within 6 s. Moreover, the sensor successfully triggered the alarm approximately 15 min before the start of thermal runaway and within 22 s after the mechanical rupture of the battery in the simulated abuse test, demonstrating the application potential of gas sensor in the early fault warning of LIB.

The composites of two or more metal oxides/sulfides have been prepared and widely used in energy storage including battery and supercapacitor. However, the composite of two activated carbon component is seldom involved. Moreover, those solid carbon sources block their contact with another carbon source and suppress the construction of rich interfaces between two components in carbon composite. In this work, an epoxy resin (EP)/phytic acid (PA) homogeneous gel is prepared by combining the solvation/de-solvation process at 80 °C and the gelation process at different temperatures (120 °C, 150 °C and 180 °C) so as to supply the rich interfaces between epoxy resin/phytic acid. Subsequently, hydrogen bond crosslinks of hydroxyl groups on the surface of the epoxy resin chains with the phosphate groups of liquid phytic acid as well as ester crosslinks are constructed. Lastly, uniform carbon composites with rich interfaces between the two components from EP and PA are acquired. The optimized activated carbon composite, i.e., AEPC-150 which is gelled at 150 °C possesses micropore-dominant porous structure and thus a high specific surface area of 1642 m 2 g −1 . In addition, AEPC-150-based electrode exhibits a superior capacitance of 435.2 F g −1 at 1 A g −1 , in which a high pseudocapacitance domain of 37.2% at 5 mV s −1 (vs. 15.6% for AEPC-120, 11.4% for AEPC-180). The symmetric supercapacitor (SSC) of AEPC-150//AEPC-150 delivers an outstanding energy density of 35.58 Wh kg −1 at a power density of 150 W kg −1 , and 20.83 Wh kg −1 even at 3750 W kg −1 .

This paper demonstrates a large-scale, flexible SERS substrate (Ag@R-SERS substrate) based on silver-decorated nano-cone arrays. The substrate was fabricated via a two-step process: pre-designed nano-cone arrays were replicated over a large area with high structural uniformity using roll-to-roll ultraviolet nanoimprint lithography (R2R UV-NIL); subsequently, silver nanoparticles (Ag NPs) were self-assembled onto the nano-cone arrays. The performances of the Ag@R-SERS substrate were evaluated using rhodamine 6G (R6G) as a probe molecule with a portable Raman spectrometer. The enhancement factor (EF) and limit of detection (LOD) of R6G detected on Ag@R-SERS substrate were determined to be 5.9 × 107 and 2.65 × 10−8 M. The relative standard deviations (RSDs) of R6G Raman intensities at 1513 cm−1 were 5.6% within a single substrate and 6.7% among different substrates. No obvious changes were observed in the line curve of R6G detected by the SERS substrate stored for 20 days. These results demonstrated satisfactory sensitivity, uniformity, reproducibility and stability. Numerical simulations were established to illustrate the electromagnetic enhancement effects of the Ag@R-SERS substrates, which were jointly attributed to the strong coupling effects of densely distributed AgNPs and Ag clusters at the tips of nano-cones. Furthermore, the potential application of the Ag@R-SERS substrate in pesticide detection was explored. Linear relationships between the SERS intensity at 1386 cm−1 and thiram concentration were established with R2 of 0.9986, 0.9940, 0.9974 and the LOD of thiram was determined to be 0.46, 0.49 and 0.55 ppm in ethanol, apple juice and tomato juice, respectively. These results confirm the feasibility of the two-step fabrication method for large-scale, flexible Ag@R-SERS substrates and their applicability for rapid and sensitive pesticide residue detection.

The advanced photocatalytic technology with conversion of renewable solar energy to the clean hydrogen (H 2 ) and hydrogen peroxide (H 2 O 2 ) chemicals can effectively realize the national goals of “carbon emission peak & carbon neutrality”. To this end, the indium sulfide (In 2 S 3 )/zinc indium sulfide (Zn 3 In 2 S 6 ) heterojunctions with double sulfur vacancies (Vs) were successfully prepared by a feasible in-situ hydrothermal approach. The as-formed heterojunctions (denoted as Vs-ISZIS6) showed the high-performance bifunctional activities towards the both photocatalytic H 2 evolution and H 2 O 2 generation. Especially, the 10Vs-ISZIS6 sample presented the highest photocatalytic H 2 production rate (7051 μmol/h/g), which is 32.1, 2.0, 14.4, and 1.4-folds greater than that of In 2 S 3 , Zn 3 In 2 S 6 , VS-In 2 S 3 , and Vs-Zn 3 In 2 S 6 , respectively. In addition, the 20Vs-ISZIS6 heterojunction possessed the optimum concentration of H 2 O 2 production with reaching 256.4 μM under 2 h of visible-light irradiation. The boosted photocatalytic performances might be caused by the synergistic effect of the presence of Vs and the construction of heterostructure between Vs-In 2 S 3 and Vs-Zn 3 In 2 S 6 , leading to the increasing visible-light absorption and promoting the photogenerated carriers separation efficiency. As a result, the possible mechanism of improved photocatalytic performances of the Vs-ISZIS6 heterojunctions was proposed. This work offers an available avenue for developing of nanostructured heterojunctions for sustainable solar-to-chemical fuel conversion.

The biochar-supported nanoscale zero-valent iron (nZVI@BC) was synthesized in the presence of ultrasonic irradiation and applied in the heterogeneous Fenton-like degradation of rhodamine B (RhB). The property changes in the nZVI@BC synthesized in the presence and absence of ultrasonic irradiation were characterized, which confirmed that the ultrasonically irradiated catalyst had a better dispersion and higher electron transfer rate, showing better catalytic performance for RhB degradation. The effects of the catalyst dosage, pH value and H2O2 concentration were investigated, and it was found that under the conditions of initial pH = 3, H2O2 concentration = 15 mmol L−1, catalyst dosage = 1.5 g L−1 and 298 K, the RhB removal efficiency of nZVI@BC(ultrasonic irradiation) was 97.7%. Furthermore, the classical second-order kinetic model showed better fitting results, suggesting that the RhB degradation was primarily controlled by a chemical reaction, and the activation energy was calculated to be 77.8 kJ mol−1. Based on quenching experiments and electron paramagnetic resonance spectra, free radicals ˙OH and ˙O2− were detected, and ˙OH was found to be the main free radical in RhB degradation. After three cycles of catalyst reuse, its removal efficiency was still more than 70%. This work provides a new route for using ultrasonic irradiation to improve the catalyst performance in Fenton-like systems.

When utilizing metal oxide semiconductor (MOS) sensors for gas mixtures detection, challenges such as low detection accuracy and susceptibility to interference from ambient humidity often arise. This research presents a method for effectively identifying gas mixtures in the presence of humidity interference. Using a single commercial sensor MQ3, dynamic response data for methanol-ethanol mixture was collected across various relative humidity levels through dynamic temperature modulation. Dynamic temperature modulation allows the sensor response to be extended in the time domain to include both gas concentration and humidity information. The linear discriminant analysis (LDA) method was used to suppress the humidity interference in the response, and the gas concentration information was retained to the greatest extent. Subsequently, the data was transformed into a two-dimensional matrix using the gramian angular field (GAF) algorithm, which was then fed into the self-developed multi-head feature extraction convolutional neural network (MFE-CNN) for concentration prediction. Experimental results demonstrate that this approach effectively reduces the impact of humidity interference, outperforming other control strategies. This method is anticipated to serve as a novel strategy for the detection of gas mixtures in the presence of humidity interference.

Polysaccharide-based supramolecular self-assembled hydrogels are promising biomaterials owing to their biocompatibility and dynamic controllability. This study was to explore the use of a polysaccharide (PSP) isolated from a well-known Chinese herb, Polygonatum sibiricum Red. (Huangjing) in the supramolecular self-assembled hydrogel. PSP was characterized as a neutral fructan with a backbone of →1)-β-D-Fru f -(2 → and →1,6)-β-D-Fru f -(2 → units bearing O-6–substituted branches. PSP/Chitosan (PSP/CS) hydrogels were prepared with different PSP concentrations (4, 6, 8, 10, 12 wt%), forming 3D network porous structure composed of nanofiber chains, with the pore size ranging from 0.67 to 13.67 μm. Increasing PSP content markedly enhanced gel strength and stability, as evidenced by higher storage modulus (G'), increased compressive modulus (0.03–0.75 kPa), and improved thermal stability (maximum degradation-rate temperature from 290 to 302 °C). In addition, PSP/CS hydrogels exhibited high swelling (2673 ± 65%) and water retention (78.26 ± 1.58%) properties. Hydrogen bonding was the predominant driving force for self-assembly. Furthermore, PSP/CS hydrogel preliminarily showed good cytocompatibility toward Caco-2 cells. In conclusion, these findings clarify the structure–assembly–property relationships of PSP/CS hydrogel and suggest a design strategy for exploiting fructan polysaccharides in advanced biomaterials.

Peroxymonosulfate (PMS), a strong oxidant with a redox potential of approximately 1.82 V, exhibits relatively low efficiency in the direct oxidation of pollutants; this has limited its further application in water pollution control. In this study, a plate-like BaTiO 3 /TiO 2 nanocomposite was successfully synthesized through hydrothermal and topochemical reactions. As an environmentally benign PMS activator, this nanocomposite effectively overcomes the limitations of single-component materials. In addition, the synergistic effect of light and ultrasound irradiation significantly enhances the efficiency of methyl orange degradation catalyzed by BaTiO 3 /TiO 2 . Systematic investigations of the influence of the BaTiO 3 /TiO 2 molar ratio show that the enhanced catalytic activity can be attributed to the formation of semiconductor heterojunctions, which not only strengthen the spontaneous polarization of ferroelectric BaTiO 3 but also facilitate the separation of photogenerated carriers and accelerate PMS activation. In summary, this study presents a novel strategy for PMS activation, providing a sustainable and efficient technological approach for wastewater treatment.

Objective: To enhance the quality and efficiency of paraffin-embedded pathological section preparation, this study aims to investigate the potential benefits of utilizing the ultrasound oscillation flotation method (UOFM) for section spreading. Methods: Specimens of various tissue types were processed using both the conventional and UOFM for section spreading. The presence of wrinkles or damage during this process was assessed through HE staining, with the number of wrinkles being quantified. The optimal frequency and power density for section spreading were determined by evaluating the qualified rate of sections at various frequencies and power densities, and the average time required for section spreading was compared between the two methods. Results: The results showed that pathological sections of various tissue types rarely showed paraffin dissolution and section breaking after the UOFM. HE staining also revealed that the group exhibited significantly reduced wrinkling and a more intact tissue structure compared with the conventional method group ( p <0.05). Statistical analysis further indicated that the highest rate of section qualification was achieved when employing a frequency of 33 kHz with a power density of 60% or a frequency of 40 kHz with a power density of 75% ( p <0.05). Additionally, the mean duration of section spreading in the group utilizing the UOFM was significantly reduced ( p <0.05). Conclusions: The UOFM effectively maintains the structural integrity of paraffin pathological sections, significantly enhancing the quality of sections and optimizing section preparation efficiency.

Constructing heterogeneous structures to precisely regulate the interface characteristics and loss mechanisms of materials is the key to performance improvement. This study proposes a strategy of constructing the NiS 2 -CdS P-N heterojunction with Porous carbon nanofibers (PCNFs) as the supporting skeleton, and deeply investigates the influence of the interface regulation mechanism of the P-N heterojunction on the absorption performance. The study clarified the structural reconstruction information such as bond parameter distortion, atomic occupation deviation, and lattice disorder caused by the Built-in electric field (BIEF) of the P-N heterojunction through X-Ray Diffraction (XRD) refinement. With the help of Density functional theory (DFT) calculation, the performance regulation mechanism of the heterojunction was revealed at the atomic/electronic scale. A carrier migration model between NiS 2 and CdS was constructed, and the absorption mechanism was analyzed. By utilizing the BIEF and space charge region formed by NiS 2 and CdS, the equivalent impedance is regulated. Ultimately, the cooperative optimization of material impedance matching and energy dissipation is achieved, providing new ideas and development of high-performance electromagnetic wave (EMW) absorbing materials. This research provides theoretical support for the subsequent shift of absorbing materials from empirical synthesis to precise design.
