Growing environmental concerns associated with phthalate plasticizers have accelerated the development of sustainable alternatives derived from renewable resources. Herein, waste cooking oil (WCO) was catalytically tailored using g-C3N4/graphene nanostructures to regulate intermolecular interactions within poly (vinyl chloride) (PVC). The influence of nanomodification on mechanical performance, thermal stability, migration resistance, and solvent durability was systematically investigated and quantitatively correlated to structure–property relationships. Among the prepared systems, the g-C3N4/graphene-modified plasticizer (P1) produced PVC films with the highest tensile strength (6.95 MPa) and Young’s modulus (890 MPa) while maintaining adequate flexibility (elongation ≈230%). Thermal analysis revealed delayed degradation with an onset temperature near 250°C, indicating restricted chain improved thermal stability. Migration measurements showed a noticeable reduction (≈3.5%), approaching the behavior of the commercial DOP reference. FTIR and SEM analyses suggest improved interfacial compatibility between PVC and the modified plasticizer, as evidenced by C = O band shifts (5–9 cm−1) and a more uniform, compact morphology with reduced microvoids. The improved performance is attributed to increased polarity, stronger dipole interactions, and reduced free volume arising from epoxy functionalities and nano-induced physical networking. This work provides direct experimental evidence linking nano-assisted chemical tailoring of waste-derived oils to suppression of plasticizer mobility and enhancement of thermo-mechanical stability. The proposed strategy offers a scalable pathway toward safer and more sustainable PVC materials.

Atomically thin, two-dimensional (2D) semiconductors offer unprecedented opportunities for high-performance gas sensing, while the limited surface accessibility of their bulk counterparts severely restricts their practical applications. Herein, ultrathin graphitic carbon nitride (g-C 3 N 5 ) nanosheets with an average thickness of ∼1.7 nm were successfully synthesized via a facile and scalable sulfuric acid-assisted intercalation–exfoliation strategy using bulk g-C 3 N 5 derived from the thermal polymerization of 3-amino-1,2,4-triazole. The exfoliation process effectively tailors the electronic structure and maximizes the exposure of nitrogen-rich active sites, enabling enhanced surface adsorption and accelerated charge transfer. As a result, the as-prepared g-C 3 N 5 nanosheets exhibit outstanding room-temperature ammonia (NH 3 ) sensing performance, delivering a high sensitivity of 22.27 ppm –1 , a low detection limit of 27 ppb, and excellent selectivity under complex gas environments. Notably, the integration of g-C 3 N 5 nanosheets onto a flexible porous substrate further enables robust mechanical stability and efficient gas diffusion, supporting reliable operation under bending and long-term use. More importantly, the sensor demonstrates the capability to discriminate pulmonary infection patients from healthy individuals through exhaled breath analysis, highlighting its potential for non-invasive clinical diagnostics. This work not only provides an effective strategy for constructing high-performance carbon nitride-based gas sensors but also offers a promising platform for wearable healthcare monitoring and early disease detection.

A novel ternary UiO-66- g -P4VP/CsPbBr₃ composite is rationally designed. • It achieves a high CO₂ reduction rate of 85.2 μmol g −1 h −1 under visible light. • The P4VP interlayer acts as a CO₂ adsorber and charge-transfer bridge. • A direct Z -scheme mechanism ensures efficient charge separation. Polymer interfacial engineering is developed to overcome the intrinsic charge-transfer barriers and instability caused by insulating ligands in MOF/perovskite composites. By covalently grafting poly(4-vinylpyridine) (P4VP) brushes onto UiO-66-NH₂, followed by in-situ confined growth of CsPbBr₃ quantum dots (QDs), we construct a ternary UiO-66- g -P4VP/CsPbBr₃ (UPC) photocatalyst. The P4VP interlayer serves triple synergistic functions including coordinating Pb 2+ to anchor ultrasmall monodisperse QDs, providing a charge transfer bridge for interfacial charge transfer, and enriching local CO₂ concentration. The optimized UPC-2 achieves an electron consumption rate of 85.2 μmol·g −1 ·h −1 for CO₂ reduction under visible light, 8.5 times that of pristine UiO-66-NH₂, with outstanding stability. Comprehensive spectroscopic, photoelectrochemical, and transient photovoltage analyses confirm a direct Z -scheme charge transfer mechanism that preserves strong redox potentials while suppressing interfacial recombination. This work establishes a versatile polymer-bridge strategy for designing durable, high-performance MOF/perovskite heterojunctions for solar fuel production.

Simple SummaryG proteins are ubiquitous in plants and play an important role in many biological functions such as plant growth and development, stress response and so on. However, their specific function in foxtail millet (Setaria italicaL.) is not clear. In this study, 12 G-protein gene family members were identified in foxtail millet and divided into four categories, and their whole-genome characteristics were analyzed. Transcriptome analysis showed that these members showed different expression patterns under salt-stress treatment at different times. This study increased the understanding of the G-protein gene family and provided valuable genetic resources for foxtail millet breeding.Heterotrimeric GTP-binding proteins, commonly known as G proteins, act as core molecular switches in plant signal transduction, governing multiple biological processes including plant growth, development, phytohormone signaling, and abiotic stress adaptation. In this study, a total of 12 G-protein-related genes were identified in foxtail millet, consisting of six Gα subunit-encoding genes, one Gβ subunit-encoding gene, and five Gγ subunit-encoding genes. Gene structure and conserved motif analyses showed that members classified into the same subunit clade possessed highly conserved exon–intron organization and motif distribution, indicating evolutionary structural conservation within each G-protein subfamily. PromoterCis-acting element analysis revealed that all G-protein family genes harbored light-responsive elements, as well as multiple regulatory elements associated with phytohormone signaling and abiotic stress responses. Transcriptome analysis showed that different G-protein genes exhibited distinct expression patterns under salt stress. Notably,SiαXLG2exhibited drastically induced expression upon salt stress, which serves as a pivotal candidate gene for salt-stress response in foxtail millet. Collectively, this study provides a systematic characterization of the G-protein gene family and offers candidate gene resources for further elucidating G-protein-mediated salt-stress regulatory mechanisms in foxtail millet.

To address the challenges of nano-active component agglomeration and incomplete energy release of boron/copper oxide metastable intermixed composites (B/CuO MICs). In this work, the energetic polyvinyl pyrrolidone- nitrocellulose- cyano modified graphitic carbon nitride semi-interpenetrating-polymer-networks (PVP-NC-g-C 3 N 4 -CN sIPNs) were constructed and utilized as substrate to fabricate high energy B/CuO MICs, in which the nanoparticles can evenly disperse on the constructed sIPNs via various covalent and non-covalent interaction due to strong polar of cyano group. The constructed sIPNs can maximize the interface contact area between nano-sized B and CuO particles, and supply more active sites for exothermic redox reaction. Meanwhile, the generated gases will blow away the formed molten B 2 O 3 and other impurities, thereby facilitating interface contact between active B core and oxygen. Thus, the B/CuO shows the highest combustion heat value (10743.8 ± 191.7 J·g −1 ) when the contents of PVP, NC and g-C 3 N 4 -CN-2 are 1.25 wt%, 5.0 wt% and 5.0 wt%, respectively, and the calculated B combustion efficiency greatly increase from 25.9% to 99.6%. Besides, the thermal stability, microwave ignition delay times, burn rate, maximum pressure and pressurization rate values were also evaluated and compared with the effect of PVP-NC and PVP-NC-g-C 3 N 4 on B/CuO. This work will improve the application of B-based MICs in the fields of military and civilian.

Tetracycline (TC) is difficult to degrade and is widely used, seriously threatening the environment and human health. This paper employed the two-step hydrothermal synthesis process to combine the different loading of urchin-like In 2 O 3 with laminar g-C 3 N 4 . After a series of experiments, it was proved that the 10.0 wt.% In 2 O 3 /g-C 3 N 4 is the optimal ratio. Its decompose efficiency of TC could reach 86.1%, and the apparent rate constant of degradation was 0.01655 min −1 simultaneously. This result is attributed to the S-scheme heterojunction structure within the In 2 O 3 /g-C 3 N 4 composite material. Through this mechanism, useless electrons and holes were eliminated via recombination, while the highly reactive photogenerated electrons in the g-C 3 N 4 ’s CB and the holes in the In 2 O 3 ’s VB were reserved for photocatalytic reactions and generated a substantial quantity of reactive species (RSs) that effectively degraded TC. This work provides several useful insights for removing TC or other organic pollutants from the water environment.

Endometriosis is a debilitating, estrogen-dependent gynecological disorder characterized by profound diagnostic delays due to clinical reliance on invasive laparoscopy. Developing noninvasive, point-of-care biomarker assessment remains a critical yet unmet medical need. Here, we report an integrated electrochemical immunosensing platform (“Flower-CN-EC”) based on a structurally engineered, petal-like graphitic carbon nitride (g-C 3 N 4 ) framework for the sensitive detection of urinary cytokeratin 19 (CK-19)-a promising candidate biomarker reflecting endometriosis-associated epithelial activity. The 3D hierarchical architecture of curled nanosheets provides an optimized microenvironment that facilitates unhindered mass transport and minimizes steric hindrance during covalent antibody immobilization. To bridge laboratory sensing with decentralized clinical translation, the sensor was coupled with a customized visual signal-processing interface featuring automated polynomial baseline correction. The sensor showed an excellent log-linear response to CK-19 (10 pg/mL-100 ng/mL), a low detection limit of 3.24 pg/mL, outstanding batch reproducibility (relative standard deviation 2.31%, n = 8), and exceptional ambient storage stability over 5 weeks. In a pilot clinical evaluation (n = 21), the platform successfully differentiated patients with histologically confirmed endometriosis from healthy controls with high statistical significance ( p = 0.0011) and AUC of 0.899. These findings establish a robust, noninvasive proof-of-concept paradigm, paving the way for low-cost, decentralized endometriosis screening and longitudinal treatment monitoring.

The accumulation of antibiotic pollutants in aquatic environments poses threats to ecosystems. Photocatalysis is a promising approach for removing these pollutants, but conventional powder photocatalysts often suffer from difficult recovery and poor stability. Therefore, developing efficient, stable, and easily recoverable catalytic materials is important. In this study, 2D g-C 3 N 4 and MoS 2 were immobilized in a polyvinylidene fluoride (PVDF) membrane to prepare a g-C 3 N 4 /MoS 2 /PVDF piezo-photocatalytic composite membrane. Under the combined action of visible light and mechanical vibration, the membrane achieved a TC degradation efficiency of 76.54%, indicating a synergistic enhancement between piezoelectric polarization and photocatalysis. The formation of C─S bonds at the g-C 3 N 4 /MoS 2 interface enhanced electronic coupling between the two phases, promoting directional migration and spatial separation of photogenerated carriers. Meanwhile, the piezoelectric built-in electric field generated by PVDF under ultrasonic excitation further suppressed carrier recombination and accelerated interfacial charge transfer. Overall, the g-C 3 N 4 /MoS 2 /PVDF membrane shows good visible-light response, piezoelectric-assisted charge separation, mass transfer, recyclability, and stability, offering a new approach for antibiotic wastewater treatment and related membrane material design.

NiO-loaded g-C₃N₄ photocatalysts (1.5–13.5 wt %) were successfully synthesized. • 5.5NiO/g-C₃N₄ achieved the highest activity with 98 % CR degradation in 1 h. • NiO incorporation shifted the CB from −0.58 V to −0.68 V, improving charge transfer. • Band gap decreased from 2.91 eV (GCN) to 2.80 eV (5.5NiO/GCN). • Co-contaminants (NaCl, Na₂SO₄) reduced degradation efficiency to 80-93 %. In this work, NiO with various mass percentages (1.5%, 3.5%, 5.5%, 7.5%, 9.5%, 13.5%) was loaded on GCN to improve the photocatalytic degradation of CR and BPA. Among all prepared samples, the 5.5NiO/GCN composite displayed the highest photocatalytic activity, achieving 98% degradation of CR and 91% degradation of BPA within 1 h. Mott-Schottky analysis revealed a conduction band potential of -0.58 V for pristine GCN and -0.68 V for the optimized 5.5NiO/GCN composite. Band gap energies obtained from the Tauc plot were 2.91 eV for GCN and 2.80 eV for 5.5NiO/GCN, confirming that NiO incorporation narrowed the band gap and enhanced photocatalytic properties. Furthermore, the influence of co-existing pollutants was also investigated. Inorganic salts (NaCl and Na₂SO₄) reduced degradation efficiencies to 93% for CR and 84% for BPA, whereas organic co-contaminants (PVA and acetone) decreased them to 80% and 77%, respectively, under identical conditions. Total organic carbon (TOC) analysis demonstrated 91% mineralization for CR and 87% for BPA over 1 h, indicating that the photocatalyst achieved significant mineralization, not just superficial degradation. Overall, these findings establish 5.5NiO/GCN as a highly efficient photocatalyst for both dye and organic pollutant removal and emphasize the critical role of co-contaminants in real wastewater scenarios.

Nanocomposites have demonstrated excellent performance as photocatalysts in various photocatalytic reactions. Herein, we developed a nanocomposite comprising modified graphitic carbon nitride (MCN) and gold nanoparticles (Au NPs) for the hydrogen evolution reaction (HER). The MCN was synthesized via co-polymerization of melamine and malonamide. The Au/MCN nanocomposite exhibited hydrogen evolution rates of 86.7 µmol·h − 1 ·g − 1 under visible light and 1281.2 µmol·h − 1 ·g − 1 under simulated sunlight, respectively. The photocatalytic HER rate of Au/MCN under simulated sunlight was enhanced by a factor of 99.3 compared to pristine g-C 3 N 4 nanosheet (CN). Controlled hydrogen evolution experiments confirmed the contribution of the surface plasmon resonance (SPR) effect. By combining HER results with conventional characterization and electrochemical tests, we elucidated the photocatalytic mechanism, revealing that the Schottky junction and SPR effect synergistically enhance the photocatalytic performance. The SPR effect was further verified by photocatalytic experiments and ultraviolet-visible diffuse reflectance spectroscopy.

Circularly polarized luminescence (CPL) materials, which exhibit their unique chiroptical properties, display great potential for applications in optoelectronics and bioimaging. However, it remains a significant challenge to synthesize CPL materials with high dissymmetry factors (g lum ) and photoluminescence quantum yields (PLQY) simultaneously. Herein, we report a deep-eutectic-solvent (DES)-assisted self-assembly protocol integrated with an active-learning (AL) framework that enables the targeted fabrication of G-quadruplex (G4) supramolecular gels with high g lum and PLQY. AL pinpointed the optimal synthesis parameters in just four iterations, dramatically accelerating material development. The top-performing gel achieved a g lum of 0.29, setting a new benchmark for nucleoside/nucleotide-based CPL materials. The maximum PLQY reached 10.64%, which represents a substantial level of performance. Furthermore, by integrating SHapley Additive exPlanations (SHAP), we elucidated the relationship between reaction parameters and target properties. Building on this result, we also demonstrated multicolor fluorescence resonance energy transfer (FRET) by incorporating dyes, successfully developing a series of multicolor CPL-active materials. This work not only provides new insights into the design of bio-based chiral CPL materials but also highlights the promising role of artificial intelligence in advancing material development.

In this study, MXene and graphitic carbon nitride (g-C 3 N 4 ) nanosheets were introduced into Poly(vinylidene fluoride) (PVDF) matrix to fabricate ternary composites with a well balanced dielectric constant and dielectric loss. The g-C 3 N 4 /MXene hybrid fillers were prepared via solution blending, followed by the fabrication of g-C 3 N 4 /MXene/PVDF composite films through solution casting. At 1 kHz, the composite film containing 6 wt% g-C 3 N 4 exhibited a high dielectric constant of 56.2 and a low dielectric loss of 0.12. The g-C 3 N 4 nanosheets effectively inhibited the self-stacking of MXene nanosheets, thereby suppressing the formation of conductive pathways and reducing the dielectric loss of g-C 3 N 4 /MXene/PVDF composites. Additionally, g-C 3 N 4 /MXene hybrid fillers enhanced interfacial polarization, promoted the formation of microcapacitor structures within the composites, and improved mechanical properties. The storage modulus of the composite film containing 6 wt% g-C 3 N 4 reached 1230 MPa, which is 2.12 times that of pure PVDF. This work presents a promising strategy for developing PVDF-based dielectric composites with superior dielectric performance.
