With the increasing demands for high-temperature resistance and superior electromagnetic wave absorption in complex environments, developing effective low-frequency (2–8 GHz) absorbers remains challenging, especially for magnetic composites with high magnetic content and dispersibility. This study proposes a hummingbird acoustic resonance mixing (HAM) strategy to fabricate FeSi@SiC composites. Compositing soft magnetic FeSi with high-surface-area nano-SiC enhances electromagnetic loss and improves the high-temperature stability of the composite material due to the partial protection of FeSi by SiC. The optimized composite achieves a minimum reflection loss of −35.9 dB and a qualified absorption efficiency of 3.9 GHz at only 3 mm thickness, along with maintained structural integrity at 800 °C. Enhanced low-frequency absorption is revealed to stem from a large-small size magnetic-dielectric structure, a high density of confined magnetic units and strong magnetic coupling, which collectively promote magnetic loss. This work introduces a new approach to designing low-frequency electromagnetic wave absorbers with high-temperature oxidation resistance by precisely tuning their dielectric and magnetic constituents, and elucidates the underlying low-frequency magnetic attenuation mechanism along with its potential applications.

In this study, a capillary coated with silver nanoparticles-modified zinc oxide nanorods (Ag/ZnO NRs) was developed as an ultrasensitive SERS substrate. The aggregation of Ag nanoparticles (Ag NPs) at the tips and sides of ZnO NRs generates high-density three-dimensional “hot spots”, which, together with the photocatalytic activity of Ag/ZnO and the extended light–analyte interaction time afforded by the capillary structure, enables efficient adsorption and in situ detection of trace pollutants. This substrate exhibits excellent SERS performance, achieving a detection limit of 10 -14 M for Rhodamine 6G (R6G), with a relative standard deviation of less than 12%, With in-situ and rapid detection of microplastics in different liquid environments such as seawater and various beverages, the detection limit of polystyrene microspheres is as low as 50 μg/mL. Therefore, our prepared substrate offers a highly sensitive and reusable solution for in-situ, real-time, and rapid monitoring of trace contaminants in liquid environments.

To address the frequent faults (e.g., bird-related hazards, wind deviation) of transmission lines under extreme environments and the limitations of traditional insulating materials (insufficient dielectric properties, poor interface compatibility, etc.), this study synthesized a disulfide-containing polyurea (DPU) with dynamic covalent bonds and prepared Halloysite nanotubes (HNTs) modified by aminopropyltriethoxysilane (APTES) to form the HNTs/DPU composite. Methods included characterizations like Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and performance tests such as contact angle measurement, breakdown strength, arc resistance, dielectric constant tests, and a tower gap breakdown test. Results showed that APTES modification enhanced interface compatibility, leading to a uniform and dense microstructure. Compared with commercial polyurea (CPU) and commercial insulating sheath (CIS), HNTs/DPU exhibited superior performance: higher glass transition temperature (Tg) and thermal stability, excellent hydrophobicity, improved breakdown strength and dielectric constant, longer arc resistance time by blocking microcrack propagation, and optimal insulation effect at 4 mm coating thickness in the tower gap test with a significantly higher breakdown voltage. In conclusion, HNTs/DPU provides a new technical solution for transmission line insulation protection under extreme conditions, with comparative data demonstrating advancements over existing materials.

Based on nanomedicine, tumor microenvironment modulation and combination therapy has become an important approach for efficient tumor treatment. Herein, we designed a multifunctional nanoparticle through layer-by-layer strategy. Dopamine self-polymerization forms cisplatin (CDDP) prodrugs encapsulated polydopamine (PDA) core, with a manganese dioxide (MnO 2 ) shell formed on the surface through in situ coating. Targeting molecule hyaluronic acid (HA) is assembled on the surface through electrostatic and coordination interactions, constituting the nanomedicine HMPP NPs. After targeted internalization by tumor cells, MnO 2 catalyzes the decomposition of intracellular hydrogen peroxide (H 2 O 2 ) to generate oxygen (O 2 ). Meanwhile, MnO 2 and CDDP prodrug deplete the intracellular glutathione (GSH) to prevent the detoxification effect to CDDP. Therefore, at the first stage HMPP NPs could circumvent the CDDP resistant tumor microenvironment by alleviating tumor hypoxia and GSH depletion. Subsequently, HMPP NPs exert photoacoustic (PA) imaging guided combinational chemo-phototherapy, leveraging the exceptional photothermal properties of PDA. Ultimately, HMPP NPs-mediated combination therapy demonstrates efficient killing of cancer cells in vitro and achieves significant tumor suppression effects in vivo . All in all, this work underscores the importance of nanomedicine mediated tumor microenvironment modulation and combination therapy in combating drug resistance for effective tumor treatment.

Shape-complementary microspheres pack into irregular postoperative cavities and act as a local curcumin reservoir. • Hydrated microsphere beds retain integrity during compression, repeated loading and fluid flushing. • Nanosheet content and laser power tune mild heat-assisted curcumin release for local tumor-cell suppression. Postoperative recurrence of triple-negative breast cancer often starts from residual cells left in an irregular lumpectomy cavity, where a short-lived drug depot is easily washed away and a weak filler gives little structural support. We designed injectable SFMA/MXene/curcumin-loaded mesoporous silica nanoparticle (Cur@MSN) microspheres as a cavity-filling chemophotothermal depot rather than a membrane-like wound dressing. XPS confirmed silica-, curcumin- and MXene-associated signals, including Ti-O contributions in the composite. Mechanical tests showed that MXene/MSN reinforcement increased single-particle stiffness and improved hydrated packed-bed compression resistance, cyclic modulus retention and anti-flushing stability. Curcumin release continued for 14 days, and near-infrared irradiation increased the 32 h release from 68.97 ± 0.55% to 82.93 ± 0.45%. Normal 10A and NIH3T3 cells retained high viability, whereas 4 T1 cells showed concentration-dependent inhibition. In vivo thermal screening identified 2.0 mg/mL MXene with 0.50 W/cm 2 irradiation as a mild heating condition (∼43 °C). In a postoperative 4 T1 model, Cur/MXene microspheres with irradiation reduced bioluminescent tumor signals, supporting a locally retained, mechanically reinforced depot for recurrence-oriented therapy.

Intestinal vaccination faces several key challenges, including limited epithelial interaction, inefficient antigen uptake, and insufficient immune stimulation. Here, we developed a virus-inspired oral nanovaccine based on spiky mesoporous silica nanoparticles (VMSNs) functionalized with Rehmannia glutinosa polysaccharide (RGP), a natural polysaccharide with favorable intestinal biocompatibility. The resulting RGP-VMSN showed enhanced intestinal retention and epithelial interaction and was associated with increased antigen accessibility within the mucosal environment, reflected by stronger antigen-associated signals at mucosal immune sites. Using ovalbumin (OVA) as a model antigen, oral OVA@RGP-VMSN vaccination was associated with increased intestinal dendritic cell activation, enhanced germinal center responses, and elevated antigen-specific antibody production, together with coordinated mucosal and systemic immune responses. Furthermore, immunization with a Salmonella enterica serovar Typhimurium lysate-loaded nanovaccine improved protection in a murine challenge model. Overall, this strategy represents a promising platform for oral and mucosal nanovaccine development.

Fiber-assisted fabrication of Polyimide/MXene composite aerogel with lightness. • Excellent thermal insulation that enables infrared camouflage and fire protection. • Outstanding mechanical resilience and superior EMI SE (68.5 dB). • Reliable pressure sensing capability to accurately detecting human motion. Fabricating polymer aerogels that merge high electrical conductivity, mechanical elasticity, and enduring stability is a critical yet demanding objective. In this work, lightweight polyimide (PI)/MXene composite aerogels were synthesized through a straightforward, sustainable method utilizing PI fiber-assisted freeze-drying and subsequent thermal imidization. The resulting aerogels possess a unique segregated architecture, providing exceptional electrical conductivity alongside superior electromagnetic interference (EMI) shielding (reaching 68.5 dB). Owing to their mechanical resilience and high conductivity, these aerogels function as dependable piezoresistive sensors for detecting human activity and physical signals, which can accurately detect pressures as low as 0.04 kPa (at 0.5% strain). Furthermore, their porous nature and minimal thermal conductivity ensure efficient heat insulation, making them promising for thermal regulation and fire safety applications. Overall, this study presents a scalable fabrication strategy and promotes the advancement of multifunctional aerogels for next-generation flexible electronic devices.

In this work, PP-TSF superhydrophobic membrane was constructed by a triple layer on the PP membrane, containing titanium layer by atomic layer deposition , silica layer by sol-gel, and fluorine layer by chemical grafting. The titanium layer worked as a transition layer, increasing the binding stability between PP and the superhydrophobic layer, the silica layer provided more hydroxyl sites for superhydrophobic modification. Meanwhile, and the fluorine layer with low surface energy was the core of the superhydrophobic property. The microstructure, porosity, and pore diameter had no significant change after modification. The contact angle of the composite membrane was up to 158 o , and the rolling angle was less than 10 o . The hydrophobicity , self-cleaning properties, and surface roughness are significantly improved after modification. The salt retention of the high salt (15 wt%) was consistently higher than 99 % during the 21-h vacuum membrane distillation experiment.

Herein, in situ chemical anchoring of nickel cobalt selenide (Ni3Se4/CoSe2) on two-dimensional (2D) black phosphorene is creatively proposed via a facile approach. The introduction of 2D black phosphorene brings abundant interfacial effects and provides fully exposed active sites. The construction of such a heterogeneous structure (BP@Ni3Se4/CoSe2) effectively buffers the volume expansion effect caused by Na ion insertion and promotes electron/ion transfer during cycling. Therefore, the BP@Ni3Se4/CoSe2 electrode exhibits superior sodium storage properties in half cells, such as a high stable discharge specific capacity (about 358.8 mA h g−1 at 1 A g−1 after 100 cycles), excellent cycling stability (up to 2500 cycles, the capacity retention rate close to 82%) and high rate performance (from the initial 0.2 A g−1 to the final 20 A g−1 and the total capacity retention rate is about 76%). In addition, BP@Ni3Se4/CoSe2 achieved a high energy density of 163.7 W h kg−1 at the power density of 136.4 W kg−1 in the sodium-ion battery full battery test. Such high performance of BP@Ni3Se4/CoSe2 is attributed to its excellent reaction kinetic characteristics. The investigation of the sodium storage mechanism of BP@Ni3Se4/CoSe2 is conducted in detail.

Due to a lower intrinsic thermal conductivity , Cu 2 S-based thermoelectric materials are attracting extensive attention. However, they still confront the problem of higher electrical resistivity, which distinctly restricts their thermoelectric application. Herein, we synthesized Ag-incorporated Cu 2-x S micro/nano composites using a hydrothermal method . It was found that the doping of Ag nanoparticles could effectively enhance the electrical transport, while the generated nanopores , caused by the sintering of Ag nanoparticles during the SPS process, reduced the thermal conductivity. As a result, a maximum ZT value of ∼1.5 was obtained at 773 K in the Cu 2-x Ag δ S (δ = 0.5%) micro/nano composites, much higher than that of the pristine Cu 2-x S micro/nano composites. This work provides a new pathway to boosting thermoelectric performance through microstructural engineering.

Conductive textiles are promising components for next-generation wearable electronics. However, it is still a challenge for current conductive textiles and wearable electronic devices to survive in harsh environments, such as extreme mechanical damages and low/high-temperature stresses. Herein, we report ultrastrong, flame-retardant, intrinsically weldable, and highly conductive metallized Kevlar fabrics (MKFs) fabricated via polymer-assisted electroless deposition (ELD) and electrodeposition (ED) techniques. The combination of ELD and ED techniques effectively metallizes the Kevlar fabrics, enabling ultrahigh conductivity (sheet resistance <0.007 Ω sq−1). More importantly, the deposited metal layers significantly enhance the anti-impact properties of Kevlar fabrics by 2–3 times. Due to the inherent properties of Kevlar and effective metal coatings, the MKFs maintain conductivity while suffering various mechanical damages (GPa-scale tensile strength, cutting, sticking, etc.), high temperatures (∼300 °C), and even flame stresses. Surprisingly, the MKFs show intrinsic weldability with traditional solder materials. The multifunctional applications of such high-performance metallized fabrics are demonstrated as textile-based conductors, heaters, and supercapacitors, all of which could survive in extremely harsh conditions.
