An electrochemical immunosensor was fabricated to identify CA15-3, a biomarker for breast cancer (BC). A composite sensor substrate made of “zeolitic imidazolate framework-8” (ZIF-8) and “reduced graphene oxide” (rGO) was chosen and its conductivity was further improved by the addition of chitosan (CS)-doped gold nanoparticles (AuNPs). The CS@AuNPs are able to conjugate with antibodies via the strong Au-S interaction, which offers multiple active sites for antibody immobilization and enhances the sensor performance. This immunosensor is capable of ultrasensitive detection of CA15-3 by specific antigen–antibody –interactions. In healthy people, normal serum CA15-3 is up to 25 U/mL. Under optimized experimental conditions, the alteration in the signal intensity measured by the sensor was related to the CA15-3 activity. The quantitative relationship was linear over 0.001–400 U/mL with a limit of detection (LOD) of 0.0031 U/mL at a “signal-to-noise ratio” (S/N) of 3 and a “correlation coefficient” (r2) of 0.9983. The developed immunosensor showed great accuracy, stability, and selectivity, and was able to detect CA15-3 in human serum samples. These results validate its potential as a reliable analytical platform for BC diagnosis and early clinical screening.

Solar-driven water evaporation for sustainable freshwater production is an efficient and economical solution to alleviate global water shortages. However, available solar evaporators still face efficiency and durability limitations. Herein, this challenge is overcome via the ingenious design of a three-dimensional (3D) monolithic porous architecture based on the reduced graphene oxide (rGO) and layered molybdenum boride (MBene). Benefiting from broad light absorption, efficient water activation and porous architecture feature, the rGO-MBene acquires an impressive rate of ~2.79 kg·m −2 ·h −1 to steam pure water under one-sun (1 kW/m 2 ), which is superior to most of state-of-the-art graphene-based evaporators reported so far. When applied to solar desalination, the rGO-MBene exhibits highly durable desalination capability with a salt-free evaporation surface. After continuous irradiation in a 3.5 % NaCl solution for 100 h, an almost constant evaporation rate of approximately 2.34 kg·m −2 ·h −1 can be maintained. Meanwhile, the rGO-MBene evaporator also demonstrates its robustness for effective production of freshwater from various wastewater sources. This work not only establishes an attractive example of rGO-hybridized architecture to achieve highly efficient solar evaporation for long-lasting salt-resistant desalination and multitasking water purification , but also provides exciting opportunities to design new MBene-based materials with the improved photothermal performance for sustainable solar conversion.

s The practical application of transition metal phosphides (TMPs) in lithium-ion batteries (LIBs) has been severely hindered, primarily due to slow reaction kinetics and significant volume changes. While optimizing nanostructures could mitigate these issues, it remains a considerable challenge. Herein, NiFeP/C@rGO composites were synthesized through a multi-step protocol, involving coprecipitation, electrostatic self-assembly, and low-temperature phosphatization. The composites feature reduced graphene oxide (rGO)-coated nano-cubic frameworks derived from Prussian blue analogues (Ni/Fe-PBA), where the rGO carbon layer serves dual functions: effectively buffering volume expansion during charge/discharge cycles and enhancing overall electrical conductivity. Furthermore, the bimetallic heterostructure synergistically optimizes electrochemical performance. Remarkably, the optimized NiFeP/C@rGO-21 electrode demonstrates outstanding cycling stability, maintaining a specific capacity of 530.4 mAh g −1 after 300 cycles at a high current density of 1000 mA g −1 .

MgFe 2 O 4 /rGO/WO 3 (MAG) Z -scheme visible light-driven photocatalyst was successfully synthesized with high purity. Synergic effects within MAG Z -scheme photocatalyst effectively enhanced the photocatalytic activity by a factor of 1.5–3.3. The photocatalytic performance was evaluated through the degradation of tetracycline (TC), ciprofloxacin (CIP) antibiotics, methylene blue (MB), direct blue 71 (DB-71), livestock and textile industrial wastewaters. MB and DB-71 degradation efficiency catalyzed by MAG reached 90.22 ± 2.56 % and 87.62 ± 2.26 % after 150 min, while these figures for TC and CIP were respectively 84.47 ± 2.16 % and 78.58 ± 2.36 %. The removal efficiency depended on contact time, pH value, catalyst dosage, pollutant concentration, and co-existing ions. Radical trapping tests and electron paramagnetic resonance spectroscopy analyses showed that superoxide anion radicals were mainly responsible for degrading the pollutants. The chemical oxygen demand and toxicology assessment revealed about 75 % of organic dyes and 67 % of antibiotics were mineralized while the toxicology of the by-products was negligible. The photocatalytic performance was high and stable after five repetitive cycles, with no discernible changes to the photocatalyst's surface properties. COD removal efficiency for textile and livestock wastewaters respectively reached 48.6 % and 42.9 %, lower than those for synthetic samples due to the presence of other organic compounds and co-existing ions, but met national technical regulations on the effluents of livestock and textile industry of Vietnam. The findings in this work provide a practical approach to mitigating hazardous organic dyes and antibiotics commonly found in textile and livestock wastewaters, thereby protecting public health and the environment.

Developing cost-effective and highly durable electrocatalysts to overcome the sluggish kinetics of the oxygen reduction reaction (ORR) is critical for the promotion of proton exchange membrane fuel cells (PEMFCs). In this work, a ternary Pd–Pt alloy/WO₃–rGO nanocomposite catalyst was synthesized by a developed two-step chemical reduction method. This strategy enabled the distribution of Pd–Pt alloy nanoparticles very tightly integrated with finely dispersed WOₓ species on conductive rGO support. Structural characterizations confirmed formation of a Pd–Pt alloy phase and strong electronic interactions between the alloy and WOₓ, which resulted in modified surface electronic properties favorable for ORR. Electrochemical characterization revealed that the Pd–Pt–WO₃/rGO catalyst presented the largest electrochemically active surface area (176.29 m² g⁻¹) and superior ORR performance, achieving a mass activity of 83.96 mA mg⁻¹ and a Tafel slope of 70.91 mV dec⁻¹ at 0.9 V vs RHE. The catalyst exhibited superior durability, retaining 94.4% of its initial ECSA after 5000 accelerated cycles, and showed the lowest charge-transfer resistance (0.88 Ω), suggesting its improved conductivity and interfacial charge transfer. The remarkable performance is attributed to the synergistic effects between Pd–Pt alloying, electronic modulation by WOₓ species, and the high conductivity of rGO. These combined features are important for high power density and long stability operability in real PEMFC applications. This study presents a practical pathway for designing high-performance, low-Pt-content catalysts for efficient and durable PEMFCs.

Nowadays, safe, toughness, flexible and wearable energy storage devices have become a research hotspot. However, the safety and stability of flexible devices are still challenging because traditional wearable energy storage devices are difficult to overcome the problems of leakage, toxic and fragile electrolyte and so on. In this study, we successfully designed and constructed a continuous porous conductive polymer PEDOT:PSS film coated graphene (rGO) and CoFe 2 O 4 nanospheres composite paper electrode material. rGO paper has the advantages of good electrical conductivity and large surface area, but the graphene sheet without oxygen group has very weak adhesion between sheets, and the surface is completely hydrophobic. The water-soluble conductive polymer PEDOT:PSS film successfully increased the toughness and wettability of the graphene composite paper, and the kinetic fitting verified that the polymer improved the rate performance and electrochemical activity of the graphene composite paper. The area specific capacitance, energy density and power density of the symmetric supercapacitor made of rGO/CoFe 2 O 4 /PEDOT:PSS paper are 229.6 mF cm −2 , 25.9 Wh kg −1 and 135.3 W kg −1 . More importantly, the device can be charged in both positive and negative directions, and when change charging direction, the electrochemical performance of the device is also excellent. This solves the safety problem caused by the wrong connection between positive and negative poles of the supercapacitor, and also makes a contribution to the safety development of flexible supercapacitors.

Z-scheme Cu 2 O-(rGO-TiO 2 ) photocatalyst was successfully synthesized via a simple three-step approach for 2,2′,4,4′-tretrabromodiphenyl ether (BDE47) reductive removal under simulated solar irradiation. Unlike the traditional heterojunction , the addition of reduced graphene oxide (rGO) enhanced the redox ability of Cu 2 O-TiO 2 by increasing charge transfer. When modifying Cu 2 O films by adding 1% rGO and coating with 70% TiO 2 , the resulting Cu 2 O-(rGO-TiO 2 ) exhibited the best photocatalytic activity for BDE47 removal. The charge transfers of Cu 2 O-(rGO-TiO 2 ) were proven to follow a Z-scheme pathway through the electron paramagnetic resonance analysis. The degradation pathways of BDE47 were elucidated by identifying intermediate products via gas chromatography-mass spectrometry (GC-MS) and gas chromatography (GC). Photo-electrons (e − ) generated from the conduction band of Cu 2 O and hydrogen protons (H 0 ) reduced from H + in water were the main contributing elements for the removal of BDE47, which response to the ortho and para debromination . Ortho-Br of BDE47 was attacked by e − and BDE28 was the dominant debromination product on the first stage. Then e − and H 0 attacked ortho-Br and para-Br of BDE28 to form BDE15 and BDE8, respectively. The concentration of BDE8 was higher than that of BDE15, suggesting that H 0 played the most important role on the second debromination stage. An effective Cu 2 O-(rGO-TiO 2 )-based Z-scheme system for BDE47 debromination was proposed in this study, which may contribute to the development of novel green technologies.

To solve severe photocorrosion of Ag 3 PO 4 , polyaniline for transporting holes and reduced graphene oxide (rGO) for transferring electrons were co-incorporated with Ag 3 PO 4 by an in-situ precipitation procedure and a following hydrothermal method , reaching the superior carrier separation efficiency via synergetic effect of PANI and rGO. Consequently, 5% rGO/Ag 3 PO 4 /PANI exhibited the excellent photocatalytic performance of 86.2% removal rate towards ciprofloxacin (CIP) within 15 min, which was much better than Ag 3 PO 4 , Ag 3 PO 4 /PANI and many reported photocatalysts . After four consecutive cycles, the composites performed better stability with 81.0% removal rate. Generally, photocatalytic activity depended on efficiencies of light absorption ( η abs ), charge separation ( η sep ) and charge injection ( η inj ). η sep of rGO/Ag 3 PO 4 /PANI was 11.5 and 8.70 folds higher than that of Ag 3 PO 4 and Ag 3 PO 4 /PANI, while η abs and η inj of rGO/Ag 3 PO 4 /PANI were not improved compared with Ag 3 PO 4 and Ag 3 PO 4 /PANI, strongly manifesting synergetic effect of PANI and rGO on Ag 3 PO 4 accelerated the charge separation and finally enhanced the photocatalytic activity . Besides, rGO greatly improved the adsorption efficiency for CIP and the maximum adsorption capacity was enhanced to be 19.4 mg/g which was 6.88 folds than that of Ag 3 PO 4 , being advantageous to enhancing the photocatalytic activity. The work offered an excellent reference for designing and constructing photocatalysts with superior charge separation showing excellent photocatalytic performance, which were potential candidates for degrading antibiotics in environmental treatment.

The composite material comprising copper phthalocyanine (CuPc) and graphene oxide (GO) is a novel functional material with broad application prospects in the field of electrochemistry. In this paper, a composite material consisting of copper coated with nitrogen-doped carbon supported on reduced graphene oxide (Cu@NC/rGO) was synthesized using CuPc/GO as the precursor through thermal treatment and carbonization processes. The porous Cu@NC/rGO composite not only provides abundant active sites but also constructs rapid ion transport pathways. Within the composite, Cu@NC nanoparticles act as effective electron transfer bridges, forming a continuous conductive network that reduces interfacial contact resistance. The hybrid dual-ion capacitor (HDIC) assembled with the Cu@NC/rGO composite material demonstrated outstanding cycling stability, achieving a discharge specific capacity of 328.6 mAh g -1 at a current density of 2.0 A g -1 after 4000 cycles. Density Functional Theory (DFT) calculations and electronic structure analysis revealed that the Cu@NC/rGO material exhibits the strongest adsorption capability toward EMIm + ions, with an adsorption energy as low as -299.02 kJ·mol -1 , accompanied by the most significant charge transfer. This work provides new design inspiration for the development of anode materials for HDIC.

Heterointerface engineering based on the built-in electric field (BIEF) for guiding the construction of nanohybrids has emerged as a feasible strategy to enhance interfacial polarization and amplify the electromagnetic energy attenuation capability. Herein, we have designed a MoS 2 hollow nanospheres (HNS)/reduced graphene oxide (rGO)/Ti 3 C 2 T x /TiO 2 composite aerogel with multiple heterointerfaces. Comprehensive experimental characterization and density functional theory calculations, reveal that the 1T/2H-MoS 2 HNS and TiO 2 derived from the self-oxidation of Ti 3 C 2 T x serve as semiconductor phases to establish effective Mott-Schottky contacts with the conductive rGO phase, thereby constructing a double BIEFs system. Under alternating electromagnetic fields, the triggered BIEFs rationally tunes the electron transport behavior at the heterointerfaces, enhancing the polarization relaxation phenomenon. The 3D network structure of the aerogel can significantly enlarge the contact area of BIEF and enhance the Mott-Schottky effect. As anticipated, the prepared MSGM-10% composite aerogel demonstrates a maximum effective absorption bandwidth (EAB max ) value of 6.56 GHz and a minimum reflection loss (RL min ) value of −67.50 dB at an extremely low filling ratio of 1.50%. Additionally, aerogel features light weight, good hydrophobicity, and stable thermal insulation performance, showcasing remarkable environmental adaptability and promising broad application prospects in electromagnetic protection and military stealth technologies.

Square-wave voltage enables rapid, efficient uranium removal, outperforming constant-voltage methods. • The rGO/CuSA-CN electrode achieves 3.34 mg/g/h uranium extraction in brine—the highest reported value. • Chlorella-pretreated biofouling quadruples uranium extraction rate, electrode maintaining 100% efficiency over 24 cycles. • Bridges desalination brine valorization with strategic uranium recovery, advancing nuclear energy circular economy. Uranium extraction from seawater is widely regarded as the most promising approach for uranium resource acquisition. However, the extremely low uranium concentration in seawater (3.3 μg/L) presents significant technical challenges. This work develops a novel rGO/CuSA-CN electrophoto-catalytic composite electrode, achieving remarkable breakthroughs in uranium recovery from desalination concentrated brine—a typical desalination brine valorization practice that converts an environmental waste stream into a strategic resource supply. Remarkably, under natural seawater pH (pH 8), the application of square wave voltage enables 98.0% uranium removal from a 10 mg/L solution within 5 min, a performance far outperforming constant voltage methods; square wave voltage enables rapid uranium deposition and sustained electrode activity by periodically reversing the potential, which inhibits passivation, promotes U(V) re-oxidation and prevents active site blockage. Furthermore, by simulating biofouling conditions with Chlorella pretreatment, we discovered an unexpected synergy that quadrupled the uranium extraction rate, reaching 3.34 mg/g/h from the pretreated brine—a rate significantly higher than most reported values for direct seawater extraction and suggesting practical viability for high-throughput processing. This finding offers a new perspective for adapting extraction technologies to real-world desalination plant conditions. In selectivity experiments, the electrode exhibited exceptional performance, with a uranium-to‑magnesium distribution coefficient ratio (K d (U)/K d (Mg)) reaching 72.6 even against the strongest interference. This work establishes a new paradigm for desalination brine valorization, transforming a problematic waste stream into a strategic resource and advancing the circular economy of nuclear energy materials.

Despite their high hardness and wear resistance, the widespread application of alumina (Al 2 O 3 ) ceramics is limited by their inherent low fracture toughness. To address this challenge, a composite reinforcement strategy incorporating high-hardness cBN and high-strength graphene nano-platelets was employed. To address the issues of poor dispersion and weak interfacial compatibility associated with direct addition, a core–shell reinforcing phase comprising cubic boron nitride (cBN) coated with reduced graphene oxide (RGO), denoted as cBN@RGO, was synthesized via electrostatic self-assembly. Al 2 O 3 /cBN@RGO composites were then fabricated using spark plasma sintering at 1350 °C under a pressure of 35 MPa with a dwelling time of 8 min. Compared to the baseline Al 2 O 3 /cBN composite, the Al 2 O 3 /cBN@RGO composite exhibited simultaneous enhancements in hardness, flexural strength and fracture toughness by 9.5 % (to 19.5 GPa), 26.7 % (to 568 MPa) and 28.2 % (to 6.81 MPa m 1 / 2 ), respectively. Microstructural analysis revealed that the cBN@RGO core–shell particles were well dispersed in the Al 2 O 3 matrix without agglomeration, exhibiting strong interfacial bonding, which effectively inhibited the detrimental phase transformation of cBN to hBN at high temperatures. The results demonstrate that the cBN@RGO core–shell design achieves a synergistic reinforcement effect, providing a novel strategy for developing high-performance ceramic matrix composites.
