The treatment of waste tritiated water (HTO) in the nuclear energy field involves the separation of H 2 O/HTO, and the vapour release process with high temperature heating is one of the proposed solutions. Such process is energy-intensive, membrane-based processes have been studied as the alternative. The efficient separation of light water/deuteriated water (H 2 O/D 2 O), which is often used as a model process for H 2 O/HTO separation, has been recently reported through membrane processes with novel membrane materials or structures, nevertheless, the effect of water feedstock conditions on separating hydrogen isotopic water with emerging novel membranes remains unexplored. Here, the separation of H 2 O/D 2 O with graphene oxide (GO) composite membranes through vapour release close to actual conditions was investigated by vapour permeation processes from the perspective of temperature and vapour pressure of water feedstock: (i) for the temperature of 288 K, 303 K and 318 K,the highest separation factor of 1.40 was obtained under saturated water vapour pressure at 288 K; (ii) for 100 %, 75 % and 32 % of saturated water vapour pressure, permeation fluxes and separation factors decreased with the decrease of vapour pressure. Furthermore, the correlation of membrane structure-separation performance was reviewed with suggested possible ways to improve separation performance. The results demonstrate that the performance of H 2 O/D 2 O separation is linked with the temperature and vapour pressure of water feedstock conditions, which provides a good foundation for developing membrane processes to treat radioactive tritiated wastewater in the nuclear energy field.

The Co-based organic skeleton was combined with graphene oxide (GO) as a precursor, Ni 2+ hydrolysis etching was introduced, and finally, NiCo-LDH/GO was obtained. The final composite electrode material NiCo 2 S 4 /rGO was obtained by high-temperature vulcanization. The introduction of MOFs and rGO significantly increased the specific surface area of the material and made it have excellent electrochemical properties. The specific capacitance of the composite NiCo 2 S 4 /20rGO reaches an astonishing 272.5 mAh g −1 when the current density is 1 A g −1 . In addition, at a large current of 10 A g −1 , the specific capacitance of the material can also reach 139.5 mAh g −1 , and after a long cycle of 5000 cycles at such a current density, the capacity remains at the original 73.2%. With NiCo 2 S 4 /20rGO electrode material as the positive electrode and activated carbon as the negative electrode, the hybrid supercapacitor is assembled. At an energy density of 56.9 Wh kg −1 , its power density reaches an excellent 799 W kg −1 , and it still has a capacity retention rate of 74% at a current density of 10 A g −1 . The excellent properties of composites demonstrated in this work open up new possibilities for high-quality energy storage devices.

Hydrogels, owing to their outstanding hydrophilicity and remarkable ability to mitigate creep and leakage issues, serve as ideal lubricants. The introduction of nanomaterials such as MXene and graphene oxide (GO) can further enhance the mechanical strength and tribological properties of hydrogels. In this study, MXene/GO-PVA composite hydrogel lubricants were prepared by incorporating the two nanomaterials of MXene and GO into the PVA hydrogel by the chemical cross-linking method, and their tribological properties were systematically investigated. Furthermore, the lubrication mechanism of the MXene/GO-PVA hydrogel was investigated and deduced through multiple analytical techniques. Compared with the base hydrogel and single-component hydrogel, the MXene/GO-PVA hydrogel exhibits the best tribological performance: its coefficient of friction is reduced by 50.68%, and its wear volume is decreased by 63.99% relative to the PVA hydrogel. The inherent low interlayer shear strength and interlayer slip characteristics of MXene and GO, combined with their surface-abundant hydrophilic groups and the synergistic effects generated within the three-dimensional PVA hydrogel network, collectively contribute to the excellent lubrication performance. This study offers insights into the development of high-performance water-based lubricants.

Effective hemostasis and pathogenic microorganism clearance are essential primary steps for establishing a stable internal microenvironment during the early stage of wound repair. Therefore, a simultaneous thermal crosslinking-integration strategy was applied to electrospun polyvinylpyrrolidone (PVP) and graphene oxide nanosheets (GO) composite fibers to achieve early-stage intervention for acute wounds. During thermal crosslinking, molecular thermal motion facilitates interactions between PVP and GO via various non-covalent interactions, thereby further stabilizing the macromolecular chains. Specifically, the fabricated PVP-G5 membranes exhibit robust morphological stability in aqueous environments, enabling them to accommodate excessive wound exudate. As a supporting substrate, the fibrous structure of PVP-G5 also facilitates platelet accumulation, thereby providing a favorable physical platform for activating the blood coagulation cascade. Furthermore, the embedded GO nanosheets within the fiber matrix not only ensure biocompatibility but also endow the fibrous membranes with NIR-switched photothermal therapy (PTT), thus achieving broad-spectrum pathogen eradication. These findings demonstrate that the PVP-GO composite fiber membranes, fabricated through the in situ thermal integration strategy during crosslinking, offer significant advantages for managing severe bleeding and infection, with promise for early treatment of acute wounds.

Adsorption materials play very important roles when used to effectively remove organic pollutants from the environment. In this paper, a novel graphene oxide/COFs (GO/COFs) composite was synthesized by the Schiff base coupling reaction between 1,3,5-tri(4-aminophenyl)benzene and 2,5-divinylterephthalaldehyde on the surface and between layers of GO at room temperature. The synthesized GO/COFs composite has a low density, large specific surface area, layered porous structure and favorable water dispersion. The adsorption behavior of the GO/COFs composite for naphthalene, 1-naphthylamine and 1-naphthol in aqueous solution was studied. Compared with GO and the COFs alone, the composite has a higher adsorption capacity, which may be due to the synergistic effect of the COFs and GO. In addition, the GO/COFs composite achieves excellent regeneration capability through ultrasound in ethanol, which is a low energy consumption and easy to operate method. This composite is hoped to be an excellent adsorbent in environmental remediation.

Fourier transform infrared (FTIR) spectroscopy, Raman spectra (Raman), zeta potential measurement, scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and differential pulse voltammetry (DPV) were adopted to confirm and investigate the chemical compositions, surface properties, morphological and electrochemical performance of the as-prepared magnetic nanocomposite (denoted as GO/PDDA/Fe 3 O 4 ). The maximum adsorption capacity of GO/PDDA/Fe 3 O 4 for Cr(VI) was 141.68 mg/g at pH = 2, and the desorption-regeneration results exhibited GO/PDDA/Fe 3 O 4 could be a potential prospective nanocomposite used for instaneous filtration-adsorption of Cr(VI) from aqueous solution in real-life situations due to its fast, effective and stable properties.

Epoxy resin (EP) coating has high hydrophilicity and poor long-term corrosion resistance . In order to improve its protection ability, an EP-graphene oxide (GO)/SiO 2 multifunctional coating is fabricated on Mg-Zn-Ca alloy in this study, through a spin/spray assisted self-assembly technique. The morphologies and microstructures of the coated samples were observed using scanning electron microscopy (SEM), Fourier infrared spectrometer (FTIR) and atomic force microscope (AFM). Hydrophobicity and self-cleaning property of the composite coating were tested by an optical contact angle meter and black graphite powders . The stability of the superhydrophobic surface was tested by rubbing with sandpaper and immersing in corrosion solution. The corrosion resistance of coated samples was tested in 3.5 % NaCl solution using electrochemical impedance spectroscopy (EIS). The GO sheets are uniformly dispersed in EP coating. EP-GO acts as a dense bottom layer, effectively promoting its adhesion with the superhydrophobic SiO 2 coating, and the water contact angle (WCA) values range from 158° to 168°. After stability testing, the WCA value of the superhydrophobic coating remains at a high level (115°–155°). The R ct of this composite coating was remarkably increased to 1.0 × 10 22 Ω/cm 2 , implying that the corrosion resistance was improved by eighteen orders of magnitude compared to bare substrate. These results show that the combination of the labyrinth effect and the hydrophobic surface extend the corrosion path and reduce the contact area of the corrosion solution with the coating, which strengthens the barrier effect of the composite coating. The composite coating exhibits superior corrosion resistance durability and self-cleaning property.

This study presents the development of a durable, superhydrophobic composite cotton fabric with enhanced photothermal antibacterial properties. Graphene oxide (GO) was first deposited onto cotton fabric to create an anchoring layer, followed by the in-situ growth of ZIF-67 nanoparticles. The fabric was further modified with polydimethylsiloxane (PDMS) to impart a low-surface-energy coating, enhancing both hydrophobicity and stability. GO not only significantly enhanced photothermal conversion efficiency, but also improved the dispersivity and adhesion of the nanoparticles. The resultant GO/ZIF-67/PDMS composite fabric exhibited excellent photothermal performance, reaching 103.2°C within one minute under near-infrared (NIR) irradiation (0.6 W/cm 2 ). The antibacterial activity of the composite was evaluated against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli . Under NIR irradiation for 5 min, the survival rates of E. coli and S. aureus were reduced to 0.01% and 9.35%, respectively. Moreover, the fabric maintained both photothermal and hydrophobic properties even after 10 washing cycles in sodium dodecyl sulfate (SDS) solution or 100 abrasion cycles, demonstrating outstanding durability. These results highlight the potential of GO/ZIF-67/PDMS composite fabric in antibacterial textile with self-cleaning property, particularly in the photothermal antibacterial application.

A flexible, eco-friendly, and photoelectrically modulated
synaptic
resistive random access memory (ReRAM) device has been developed using
a lead-free nanoscale Cs 3 Bi 2 I 9 Quantum
Dot (QD) graphene oxide (GO) composite film. The Ag/PMMA/Cs 3 Bi 2 I 9 QD/GO/ITO device exhibits a remarkable
ON/OFF ratio exceeding 10 4 under illumination, representing
approximately 200-fold enhancement compared to its performance in
darkness (∼10 2 ). The device demonstrates exceptional
mechanical and environmental stability, withstanding 10,000 bending
cycles (4.6 mm radius) and 72 h of ambient exposure (25 ° C, 35%
RH). Furthermore, when implemented in an artificial neural network
(ANN) for supervised learning, the device enables a recognition accuracy
of 94.3%. We attribute this enhanced performance to a synergistic
mechanism associated with the nanoscale dimension and uniform dispersion
of Cs 3 Bi 2 I 9 QD in the composite.
First, a poly(methyl methacrylate) (PMMA) protective layer effectively
suppresses leakage current, thereby elevating the high-resistance
state (HRS). Second, photogenerated holes within the Cs 3 Bi 2 I 9 QD are efficiently trapped, promoting
the formation of I – vacancies (V I – ). This synergistic effect facilitates the formation
of hybrid Ag/V I – conductive filaments,
reducing both SET voltage (by 47.7%) and low-resistance state (LRS)
resistance under illumination. These findings underscore the pivotal
role of optoelectronic coupling in optimizing resistive switching
behavior, paving the way for sustainable neuromorphic computing systems.

To overcome the intrinsic limitations of polymer-based phase change gels, including low thermal conductivity, supercooling, and insufficient mechanical robustness, self-healing hydrogel-based form-stable phase change materials (FPCMs) were designed by in situ polymerization of graphene oxide (GO)- or aluminum oxide (Al 2 O 3 )-enhanced 1-ethyl-3-methylimidazolium tetrafluoroborate ([Emim][BF 4 ]) nanofluids within a dynamic poly(N-isopropylacrylamide-co-UPyMA) network. The incorporation of quadruple hydrogen-bonding UPy motifs endowed the polymer network with intrinsic self-healing capability and mechanical adaptability. Uniformly dispersed GO and Al 2 O 3 nanofillers significantly enhanced heat transport and crystallization behavior. At optimized loadings, the nanofluids exhibited markedly suppressed supercooling, and the phase transition temperature of the FPCMs could be effectively tuned by adjusting ionic liquid content, with melting point shifts exceeding 5°C. GO-based FPCMs completely eliminated supercooling, while Al 2 O 3 -based systems achieved an over 85% reduction. High latent heat values above 230 J/g were retained, together with thermal conductivity enhancements exceeding 140% compared to the neat ionic liquid. Benefiting from the dynamic polymer network, the FPCMs showed excellent self-healing performance, with strength recovery exceeding 80% and good durability upon repeated damage–healing cycles. This work highlights a polymer network engineering strategy for constructing multifunctional FPCMs with tunable thermal behavior, efficient crystallization regulation, and mechanical resilience for thermal energy storage applications.

The epoxidation of long-chain α-olefins is an effective strategy for optimizing synthetic oil products and expanding their high-value-added derivatives. Tungsten trioxide (WO 3 ) is a promising catalyst for this reaction, yet pure WO 3 suffers from low specific surface area and a high density of Brønsted acid sites (B acid), resulting in poor activity and selectivity. Herein, graphene oxide (GO) was employed as a support to anchor WO 3 via an in situ growth strategy. Leveraging the strong interaction between the oxygen-containing functional groups of GO and the acidic hydroxyl groups of WO 3 , we achieved both high dispersion and effective reduction of B acid sites on WO 3 , successfully fabricating a high-performance WO 3 /GO catalyst. In the epoxidation of 1-octene, the WO 3 /GO catalyst exhibited excellent performance, specifically, its catalytic activity for producing 1,2-epoxyoctane increased from 7.9 mmol g WO 3 −1 h −1 (pure WO 3 ) to 20.3 mmol g WO 3 −1 h −1 , representing a 2.6-fold enhancement in catalytic efficiency. The catalyst also exhibited excellent performance towards other long-chain α-olefins. This study provides a simple, efficient, and dual-benefit strategy for the structural modification of WO 3 -based catalysts, offering a promising approach for designing low-acid, highly dispersed metal oxide catalysts for the efficient conversion of long-chain α-olefins. In situ anchoring of WO 3 onto GO enables high dispersion and reduced B acidity, boosting 1-octene epoxidation activity by 2.6 times.
