The quick improvement of up-to-date communication technology has generated ubiquitous electromagnetic wave (EMW), which poses a significant hazard to environment and human health. One of the key challenges associated with EMW is to develop highly lightweight and efficient adsorption materials that are able to alleviate the unfavorable interferences in wide-ranging frequency. Herein, we fabricated a hybrid porous carbon nanofibers (CNFs) membrane combined with reduced graphene oxide (rGO) and magnetic nanoparticles by electrospinning process followed by calcination . The composite membrane exhibited high-efficiency absorbing abilities due to its particular porous structure and introduced components in the final sample. Specifically, both cobalt and iron nanoparticles captured into CNFs are advantageous to the electrical conductivity of the membrane by lessening the contact loss via creating the metal-metal crossing points within membrane. The introduced components are capable of enhancing the absorption performance due to the improved permittivity ( ε r ) and permeability ( μ r ) in the composite structure. The minimum reflection loss (R L min ) value was demonstrated to be −43.60 dB at 5.84 GHz with a matching thickness of 5 mm. The synthesis of nanofibrous composite in this work identifies a new direction to fabricate advanced EMW absorption materials towards broad practical applications.

In this contribution, we demonstrated an efficient approach for constructing conductive aramid nanofibers based porous architectures by graphene oxide and Ti 3 C 2 T x via freeze drying and subsequent thermal reduction. Specifically, the aramid nanofibers laid the foundation for mechanical enhancement and good electrical conductivity of Ti 3 C 2 T x and RGO ensured outstanding electromagnetic shielding ability. The resultant Ti 3 C 2 T x /RGO/ANFs hybrid aerogel presented a spongy structure, which was conducive to the dissipation of incident electromagnetic waves through multiple reflection and scattering. The electromagnetic shielding efficiency reached 54.8 dB in X-band (8.2–12.4 GHz) with 25 wt% loading content of Ti 3 C 2 T x . When the addition amount of Ti 3 C 2 T x was 5 wt%, the optimum compressive stress of Ti 3 C 2 T x /RGO/ANFs hybrid aerogel reached 200 kPa under 70% strain with a relatively low density of 0.062 g/cm 3 . This work provided a feasible approach to fabricate robust hybrid aerogel with excellent electromagnetic shielding performance and compression resilience.

SiO(silicon monoxide) anode have received widespread attention owing to the great potential for the development of modern society. Although SiO has a large Li capacity, the short cycle life, poor rate capability and low coulombic efficiency limits its wide applications. In this paper, we adopt hydrothermal mixing and sintering process to form a ball milling bm-SiO based, Ni doped and rGO recombined composite (bm-SiO/Ni/rGO) anode material , which shows excellent cycle performance with the initial columbic efficiency of 65%, the discharge capacity of 720 mAh g −1 at 100 mA g −1 current density after 100 cycles and good rate performance. The improvement of electrochemical performance can be ascribed to the interaction effects of the limited damage of volume change, the open structure of reduced graphene oxide, and the cycle stability with the Ni doping.

Antimony sulfide (Sb 2 S 3 ) is a promising absorber for photovoltaics operating under both outdoor and indoor illumination due to its suitable bandgap and excellent photostability. However, during chemical bath deposition, the unsynchronized hydrolysis and sulfidation of Sb 3+ species induce excessive homogeneous nucleation, leading to amorphous particles and ultimately films with small grains, high grain boundary density, and low crystallinity. To address this issue, an rGO-regulated deposition strategy is developed. The oxygen-containing functional groups on rGO can interact with Sb 3+ species through coordination and electrostatic interactions, thereby modulating their local availability and reaction kinetics. This suppresses homogeneous nucleation and promotes substrate-guided growth, yielding Sb 2 S 3 films with [ hk 1] preferred orientation, enlarged grains, reduced defects, and improved carrier transport. As a result, the photovoltaic device with rGO-regulated achieves a PCE of 7.61% under AM 1.5G illumination (compared to 7.15% for the conventional CBD device) and 17.64% under 3000 K, 1000 lux warm white LED illumination. This work highlights Sb 2 S 3 as a versatile absorber for outdoor–indoor photovoltaics and provides a pathway for regulating solution-phase crystallization.

Two-dimensional layered materials are prone to interlayer stacking in gas sensing applications, leading to a reduction in specific surface area, slow gas diffusion, and inadequate response performance at room temperature. To address these issues, this study employed a combined hydrothermal reduction and freeze-drying method to prepare 3D rGO/MXene/In 2 O 3 composite aerogels, and systematically investigated their microstructure, pore structure, surface chemistry, and formaldehyde sensing behaviour at room temperature. The results indicate that this composite material possesses a continuous, interconnected three-dimensional porous network structure and a high specific surface area (282.78 m 2 /g), which effectively exposes active sites and accelerates gas transport. First-principles calculations confirm the presence of significant interfacial electronic interactions between the multiple components. Under room-temperature testing conditions, the aerogel-based sensor demonstrated a rapid response recovery time (6/8 s) and high formaldehyde response sensitivity (50 ppm, 26.9%), providing an experimental foundation and material design reference for the development of novel room-temperature rapid gas sensors.

The aerospace, military stealth, and 5G communication fields have raised new requirements for multifunctional materials. In this study, a rigid MWCNT/Co@C/rGO/PMI composite foam (MCGP) was prepared using a UV light-initiated in-situ copolymerization hot air foaming method. The sandwich structure of MOF-GO-MOF, after calcination, achieved a uniform dispersion of magnetic Co particles and formed rich hetero interfaces. The 0D Co@C, 1D MWCNT, and 2D rGO formed a multi-dimensional filler system, and the magnetic-electrical synergy and isotropy bubble structure jointly optimized the impedance matching, and multiple loss mechanisms enhanced the absorbing performance. The results showed that M20C20/PMI achieved a RL value of -68.26 dB at a frequency of 8.92 GHz and a thickness of 40mm, and the EAB covered the full frequency band of 2—18 GHz. The RCS value of M25C15/PMI reached a minimum of -45.82 dB·m 2 . Notably, by carefully adjusting the proportion of fillers, the five MCGP composite foams prepared in this study all had a minimum RL value of < -55 dB, basically meeting the requirements of each absorption frequency band. In addition, the MCGP composite foams are lightweight (28.30 kg/m 3 ), have high strength (0.50 MPa), heat insulation (0.02856 W/(m·K)), and infrared stealth characteristics, making them promising as a new generation of integrated structural–functional protective materials.

An efficient electrochemical platform for determination of Gatifloxacin. • ZrMo 2 O 8 /rGO demonstrated remarkably synergistic effect toward Gatifloxacin. • Wide response range (0.1–10 μM), low LOD (0.02 μM) and good stability (10 d). • High sensitivity in the detection of Gatifloxacin in tap water and honey. Although antibiotics such as Gatifloxacin (GAT) offer therapeutic benefits, their potential adverse effects on human health necessitate the development of highly sensitive and selective detection methods. Here, we report a novel electrochemical sensor for trace GAT detection in complex matrices, fabricated by integrating bimetallic oxide zirconium molybdate (ZrMo 2 O 8 ) nanoparticles with reduced graphene oxide (rGO) nanosheets. The synergistic combination of ZrMo 2 O 8 nanoparticles, a bimetallic oxide with superior electrocatalytic activity, and rGO nanosheets, which provides an exceptionally high specific surface area and electrical conductivity, enables high-performance GAT sensing. Under optimized conditions, the ZrMo 2 O 8 /rGO modified glassy carbon electrode (ZrMo 2 O 8 /rGO/GCE) demonstrated a wide linear range (0.1–15 μM), a low limit of detection (0.02 μM) and high sensitivity (7.040 μA μM −1 ). The ZrMo 2 O 8 /rGO/GCE also exhibited excellent repeatability, reproducibility, and remarkable anti-interference capability even in the presence of excess interfering substances. Notably, the ZrMo 2 O 8 /rGO/GCE maintained comparable sensing performance in real-world samples (tap water and honey), achieving recoveries of 98.40%–105.0% and highly consistent sensitivity with PBS buffer. This work presents a cost-effective, rapid-response, and highly sensitive electrochemical platform for trace GAT detection in complex samples, with promising applications in environmental and food safety monitoring. A highly efficient electrochemical sensing platform was developed for the detection of trace Gatifloxacin residues in tap water and honey, based on bimetallic oxide ZrMo 2 O 8 nanoparticles integrated with reduced graphene oxide (rGO) nanosheets.

With the popularity of wireless communication technology, the problem of electromagnetic radiation and interference is highlighted, and the development of efficient electromagnetic shielding materials has become a research priority. In this study, firstly, polyvinyl alcohol/sodium alginate (PVA/SA) hydrogels were prepared by physical cross-linking method, and further, iron-based metal-organic frameworks (Fe-MOFs) were prepared by solvothermal synthesis method, and with reduced graphene oxide (RGO) as a conductive filler, and γ-aminopropyltriethoxysilane (KH550) as a cross-linking agent, were prepared by chemical cross-linking method. Modified polyvinyl alcohol/sodium alginate/iron based metal organic framework/reduced graphene oxide (PVA/SA/Fe-MOF/RGO-KH550) composite hydrogel. The results show that the composite hydrogel has a compressive stress of 20.13 MPa, a compressive strain of 83.28 %, and an electromagnetic shielding efficiency of 39.98 dB at a thickness of 3 mm, which reaches the mid-range and high-end level, and it can be applied to industrial control, small and medium-sized data centres, automotive electronics, and general medical devices with medium-high requirements. The excellent performance of the hydrogel comes from the conductive properties and interfacial polarisation effect of RGO, the dielectric loss of Fe-MOF, which work in synergy, and KH550 optimises the interfacial bonding between the filler and the substrate to form a denser crosslinked structure, which strengthens the mechanical properties and electromagnetic shielding effect. The hydrogel preparation process is simple and low-cost, which provides a reference for the design of high-performance electromagnetic shieldingmaterials and an effective solution to the problem of electromagnetic interference.

As an efficient method to realize photoinduced shape memory, photothermal filler has the characteristics of economy and convenience. However, the aggregation of the photothermal filler in the matrix material will reduce the material's shape memory and mechanical properties. In this work, the photothermal filler of reduced graphene oxide (rGO)-titanium dioxide (TiO 2 ) was prepared by the solvothermal method and then introduced into the polycaprolactone (PCL) matrices to construct a photoresponsive actuator. Because of TiO 2 is uniformly loaded on the rGO surface, rGO-TiO 2 disperses well in the composites. When the GO:TiO 2 ratio of photothermal filler is 1:1, the mechanical properties of PCL-GT-3 are the best, and the tensile strength and elongation at break are 31.8 MPa and 239.5%, respectively, and the crosslinking material under near-infrared light has a good photothermal effect. Due to the induced difference between the in-plane stress of the surface and the volume layer, the shape transformation can be controlled by very low energy (808 nm, 700 mW near-infrared laser). The scheme of controlling the properties of the photoinduced shape memory material by changing only the filler type is conducive to commercial application.

To address the key challenges in the synergistic optimization of low-cost fabrication, high sensing performance in wearable electronic textiles, this study developed a flexible pressure sensor based on cotton fabric modified with a synergistic combination of reduced graphene oxide (RGO) and carbon nanotubes (CNTs). Through a simple and efficient ultrasonic-assisted immersion combined with a chemical in-situ reduction process, a uniform RGO/CNTs hybrid conductive network was successfully constructed on the surface of knitted cotton fabric fibers, forming a sensing layer with a hierarchical microstructure. System characterization and performance evaluation demonstrated that the synergistic effect of RGO and CNTs significantly enhanced sensor performance: compared to single RGO modification, the composite sensor’s sensitivity increased by 131% (from 0.99 to 2.29 kPa⁻¹), while the pressure detection range was expanded to 0～142 kPa. Benefiting from the layered porous structure of the textile substrate and stable interface bonding, the sensor demonstrates outstanding comprehensive performance, including high sensitivity (2.29 kPa⁻¹) in the low-pressure range (0～25.69 kPa), fast dynamic response (response/recovery time: 84ms/92ms), a wide linear detection range (0～142 kPa), and excellent mechanical stability (no significant performance degradation after 12,000 compression cycles). Practical application verification confirms that this sensor can be used in fields such as human health monitoring, motion monitoring, and voice monitoring, demonstrating its potential applications in wearable electronics and smart clothing.

Many electrochemical glucose sensors rely on enzymatic catalysts such as glucose oxidase (GOx). However, such enzyme-based sensors are susceptible to environmental perturbations, which can compromise sensitivity and measurement reproducibility. Here, we report a flexible, enzyme-free sweat-glucose sensor for wearable diagnostic systems by co-depositing hydrothermally prepared zinc oxide–cerium oxide/reduced graphene oxide (ZnO–CeO 2 /rGO) nanocomposites onto laser-scribed graphene electrodes (LSGE) patterned on polyimide (PI) films. Scanning electron microscope (SEM), X-ray diffraction (XRD), UV–vis spectroscopy, and Raman spectroscopy verified the formation and structural integrity of the hybrid nanocomposite. The electrochemical characterization, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), indicated accelerated charge transfer after modification. Under optimized conditions, the biosensor quantified sweat glucose over 0.01–3.0 mM with a sensitivity of 32.5 μA·mM −1 cm −2 and a low detection limit of 14 μM. Proof-of-concept measurements on volunteers before and after meals further supported its feasibility for wearable and personalized healthcare diagnostics.

In this paper, Pd catalysts supported on novel composite carbon supports were synthesized by the carbonization and hydrogen reduction of Pd 2+ -doped bacteria containing Ketjen EC600JD, CNT and rGO, respectively. The analysis results show that the prepared catalysts exhibit excellent ORR electrocatalytic performance in acid medium. The best ORR electrocatalytic performance was obtained for Pd/carbonized-bacteria-rGO, which exbibits a mass activity at 0.345 A mg −1 that is 9.58 times higher than commercial Pd/C, and meanwhile displays a better stability than that of Pd/C. The enhanced performance can be attributed to nitrogen doping and flexible carbon-coating microstructure. Herein, we elaborate an efficient and ecofriendly method for the synthesis of electrocatalysts used for oxygen reduction reaction.
