In recent years, Ag-In-Ga-S (AIGS) quantum dots (QDs) have received widespread attention as non-toxic and environmentally friendly QDs. However, the low photoluminescence quantum yield (PLQY) restricts the further application of AIGS QDs in optoelectronic devices. Here, we constructed quinary Ag-In-Zn-Ga-S (AIZGS) QDs with outstandingly high PLQY of 92.1% by doping Zn into AIGS QDs via an economical and environment-friendly hydrothermal method. The synergistic action of the internal doped Zn providing radiative recombination channels and the surface doped Zn passivating the non-radiative recombination defects leads to enhanced PLQY of QDs. The corresponding QDs backlight films fabricated based on AIZGS QDs and polyvinyl alcohol (PVA) also show a high PLQY of 82.7%. The improved PLQY of AIZGS QDs is comparable to other toxic metal-containing QDs in the same spectrum. Furthermore, the PL peak wavelength of the QDs can be tuned from 545 nm to 616 nm by varying the Ag/In ratio. The realization of high PLQY in aqueous AIZGS QDs and its backlight films contributes to the application in the field of eco-friendly backlight display devices.

Xanthine (XA) and hypoxanthine (HA) are key biochemical markers of meat freshness, yet rapid, wide-range, and enzyme-free quantification in complex meat matrices remains challenging. Here we report a density functional theory (DFT)-guided Cu–MoS 2 /g-C 3 N 4 heterostructure electrochemical sensor for broad-range non-enzymatic detection of XA and HA. The heterojunction prepared via a hydrothermal and ultrasonic strategy provides an efficient charge-transport pathway and enriched catalytic interfaces. DFT calculations reveal pronounced interfacial charge redistribution and strong adsorption of XA and HA on the Cu–MoS 2 /g-C 3 N 4 surface, with adsorption energies of − 0.98 eV for XA and − 2.16 eV for HA, explaining the boosted electrooxidation response. The sensor achieves low detection limits of 0.15 μM for XA and 0.28 μM for HA and wide linear ranges from 0.913 to 1643.5 μM and from 0.918 to 1653.1 μM, respectively, and enables simultaneous quantification from 0.5 to 400 μM with excellent linearity. Good stability, reproducibility, and anti-interference capability are obtained. In real meat samples, recoveries from 90.7% to 108.3% for XA and from 91.3% to 111.4% for HA agree well with high-performance liquid chromatography, supporting rapid meat freshness evaluation.

Highly efficient synergistic catalysis is achieved by constructing a dual two-dimensional MoS 2 /ZnFe-layered double hydroxide composite (2D/2D MoS 2 @ZnFe-LDH) and coupling photocatalysis and Fenton-like process to address the drawbacks of the traditional Fenton-like system. The layered structure of ZnFe-LDH enables firm anchoring and uniform dispersion of Fe active sites within the layers without forming clusters, meanwhile enhancing mass transfer efficiency and accelerating both peroxymonosulfate (PMS) adsorption and reactive oxygen species desorption. The constructed 2D/2D heterojunction strengthens interfacial covalent bonding and compatibility, shortens the migration distance of photogenerated carriers, thereby significantly improving the charge separation efficiency, which accelerates the Fe(III)/Fe(II) cycle for sustainable catalysis across a broad pH range without Fe sludge aggregation. Comprehensive analysis of EPR, in-situ XPS, quenching and probe experiments, and DFT indicates that PMS is efficiently adsorbed onto Fe sites and reduced to generate SO 4 •- and •OH. Meanwhile, further characterization combining EPR, determination of surface Fe(II) concentration, in-situ photoelectrochemical and Raman measurements, XPS and DFT confirms that photogenerated electron can simultaneously reduce Fe(III) and promote radical desorption, thereby achieving sustainable catalysis. Hence, the system achieves complete phenol removal with a high synergistic index and figure of merit of 9.69 and 2.62 × 10 −10 mol·L −1 ·h −1 ·g −1 ·J −1 , respectively. It also operates efficiently in various complex water matrices and maintains stable operation over 24 h in the continuous-flow reactor, demonstrating strong anti-interference capability without any biological toxicity. In conclusion, this study proposes a new strategy to develop for developing high-performance and sustainable photo-Fenton-like dual-system.

Thyroid hormones (THs) are key regulators of early development and metamorphosis in vertebrates, implying possible developmental roles in invertebrates. Given the importance of embryonic growth and survival to oyster seed quality and aquaculture success, understanding TH function during oyster embryonic development is therefore essential. This study investigated the effects of thyroxine (T4) concentration and exposure duration on the embryonic and larval development of Fujian oyster ( Crassostrea angulata ) . T4 was administered both by immersing female broodstock and by directly exposing embryos to T4-enriched seawater. Additionally, thiourea was used to inhibit endogenous TH synthesis in broodstock, followed by T4 treatment of their embryos. Each concentration-duration treatment was performed in triplicate, with 0.01 N NaOH serving as the vehicle control. Results showed that low to medium T4 concentrations (1.29 × 10 −9 mol/L, 1.29 × 10 −8 mol/L, 1.29 × 10 −7 mol/L) significantly enhanced the hatching rate and shell length (μm) of D -shaped larvae compared to controls ( P < 0.05). In contrast, high T4 concentrations (1.29 × 10 −5 mol/L, 1.29 × 10 −6 mol/L) exhibited significant inhibitory effects ( P < 0.05), which intensified with prolonged exposure durations. Using a validated Chemiluminescence immunoassay, results indicated that prolonged exposure may lead to cumulative T4 accumulation, contributing to developmental inhibition. Compared to direct embryonic exposure, the maternal approach potentially appeared to mitigate the inhibitory effects associated with direct high-dose exposure. Additionally, in the 1.29 × 10⁻⁸ mol/L group, an elevated triiodothyronine to T4 ratio was observed from the cleavage to the blastula stage, potentially explaining the observed developmental advantages. In conclusion, this study clarifies the dose- and time-dependent regulatory roles of T4 in early bivalve embryogenesis. While limited to the D -larval stage, these findings provide preliminary theoretical insights into TH dynamics that may inform future aquaculture seed production strategies.

Defect-rich heterointerfaces integrated with adjustable crystalline phases and atom vacancies as a promising strategy to boost electromagnetic wave (EMW) absorption. However, challenges remain in precisely controlling the balance between construction and the electromagnetic loss mechanism. In this study, an innovative Co-MoS2-xOx@NC core-shell fiber with multiple loss mechanisms was synthesized through an in-situ growth and carbonization process. This structure ingeniously combines ZIF-67 with a carbon fiber (CNF) conductive network to form continuous conductive pathways, providing an ideal medium for conduction loss. Simultaneously, Co ions embedded between MoS2 layers induce strong lattice distortion and abundant vacancies, forming numerous heterointerfaces between Co, MoS2, and CNF. Significant differences in electron density and charge redistribution at the interface greatly enhance interfacial polarization loss. MoS2 stacked nanosheets extend the transmission path of EMWs, dissipating electromagnetic energy by enhancing multiple reflections and scattering. Consequently, Co-MoS2-xOx@NC fibers achieve a strong EMW with a minimum reflection loss of −66.43 dB at 1.98 mm and a wide effective absorption bandwidth of 5.80 GHz at 1.87 mm. This study highlights synergistic effects of lattice vacancies and heterogeneous interfaces, offering a promising solution for constructing an advanced CNF matrix wave-absorbing material.

Photoinduced cathodic protection (PICP) technology exhibits substantial research significance in the field of corrosion science. This work designed and fabricated a nanocomposite-structured photoelectrode (Ti-MIS/ZIS) composed of an In₂S₃/MgIn₂S₄ composite (MIS) and ZnIn₂S₄ (ZIS) on an etched titanium sheet via a two-step hydrothermal method. The Ti-MIS/ZIS photoelectrode exhibits a significantly broadened visible-light absorption range as well as rational band alignment. The uniform anchoring of ZIS nanosheets on the Ti-MIS surface constructs a gradient band structure, and the resultant built-in electric field drives the migration of photogenerated electrons toward the conduction band of Ti-MIS, thus enabling efficient carrier separation. The rational band structure of Ti-MIS/ZIS enables abundant generation and directional migration of photogenerated electrons to the 316 L SS surface, thus realizing effective PICP. Under AM 1.5 G illumination, the Ti-MIS/ZIS photoelectrode coupled with 316 L SS achieves a photoinduced current density of 40 μA·cm⁻² and a negative shift of open-circuit potential to −0.47 V, exhibiting remarkably superior PICP performance to other photoelectrodes.Via band engineering design, this work achieves precise directional regulation of photogenerated carrier dynamics, laying a direct theoretical foundation for the development of high-efficiency heterojunction photoelectrode systems. Moreover, the revealed interfacial charge transfer mechanism exhibits universal guiding significance for heterojunction systems.

Phenolic compounds, including catechol, pose significant environmental threats due to their high toxicity and low biodegradability. However, owing to the complex procedures, high cost, and low specificity of the present detection techniques, the on-site and real-time monitoring of catechol in real water remain challenging for practical use. In this work, we developed a FeS-rGO micro-nanocomposite-based biosensor for trace catechol detection in water. The material was engineered through a hydrothermal and oriented self-assembly approach that enabled in-situ growth of flower-like FeS on rGO, effectively preventing FeS agglomeration and enhancing interfacial integration. This designed structure synergistically combines the high surface area of FeS with the conductivity of rGO, promoting efficient electron transfer and catalytic activity. After laccase immobilization, the biosensor exhibits high selectivity for catechol against interfering phenols, with a sensitivity of 253 μA·mM −1 ·cm −2 and a broad linear range from 10 nM to 8.12 mM, which demonstrates potential application in the early-warning and treatment of environmental pollutant leakage.

Two-dimensional (2D/2D) heterojunction photocatalysts hold great promise for solar-driven antibacterial disinfection owing to their unique interfacial architectures and tunable electronic properties. However, insufficient interfacial electronic coupling and ineffective charge separation still hinder their practical performance. Here, a sulfur-doped g-C 3 N 4 /Ti 3 C 2 Tx-MXene (SCN/MXene) 2D/2D heterojunction is rationally designed to enable efficient charge separation and transfer, delivering superior solar-driven antibacterial activity with remarkable stability. Combined experimental and theoretical analyses reveal that sulfur doping modulates the electronic structure of g-C 3 N 4 , elevates its Fermi level, and strengthens interfacial electronic coupling with Ti 3 C 2 Tx-MXene, thereby enhancing the built-in electric field and facilitating charge transfer across the interface. Moreover, S-doping induces interfacial charge redistribution, enhancing O 2 adsorption and activation at Ti sites and thereby accelerating the generation of reactive oxygen species (ROS). Consequently, SCN/MXene achieves nearly complete inactivation of Escherichia coli , Staphylococcus aureus , and methicillin-resistant Staphylococcus aureus within 60 min under solar irradiation, outperforming most of the state-of-the-art photocatalysts.

The practical application of solar-driven interfacial evaporation (SDIE) is fundamentally challenged by inefficient heat distribution and salt accumulation. This work introduces an Arc-Modulated Block Geometry (AMBG) aerogel evaporator that overcomes these limitations through synergistic geometry-angle coupling. This unique design features a semicircular dual-side structure tilted at 60° and integrated into a lightweight porous network, which not only establishes bidirectional heat-transfer pathways to homogenize temperature fields and suppress hotspots, but also directs salt-crystallization toward the edges, effectively preventing pore blockage. The resultant evaporator delivers a high evaporation rate of 2.88 kg m −2 h −1 and energy efficiency exceeding 93% under one-sun illumination, with remarkable long-term stability in high-salinity environments. Our strategy pioneers a shift from conventional planar design to intelligent three-dimensional structural modulation, providing a promising structural paradigm for efficient and durable solar desalination.

Alkaline phosphatase (ALP) is a critical biomarker for the diagnosis of various diseases. Consequently, the precise detection of ALP activity is indispensable for clinical diagnosis, biomedical research, and the screening of enzyme inhibitors. Meanwhile, organophosphorus pesticides (OPs), a class of highly toxic and persistent environmental contaminants, have raised significant concerns due to their extensive use in agriculture and their potential risks to both ecosystems and human health. Here, we developed a novel photoelectrochemical (PEC) biosensing platform based on an optimized CdS@In₂S₃ heterojunction for the detection of ALP activity and OPs compounds. Through systematic optimization of the In₂S₃ incorporation ratio, a significant enhancement in photoelectric conversion efficiency compared to pristine CdS was achieved. The sensing mechanism exploits the synergistic effects of the ALP mediated hydrolysis of L-ascorbyl-2-phosphate trisodium salt (AAP) to generate ascorbic acid (AA) and the AA-induced photocurrent amplification of the CdS@In₂S₃ heterojunction. This dual signal amplification strategy enabled ultrasensitive detection of ALP activity with a wide linear range of 0.17–17,000 U/L and an exceptionally low detection limit (LOD) of 0.0083 U/L. Chlorpyrifos (CPF) inhibits the activity of ALP, thereby reducing the amount of AA generated from AAP catalyzed by ALP. This results in attenuation of the AA-dependent photocurrent signal. By quantifying the degree of such photocurrent suppression, highly sensitive detection of CPF was achieved with a broad dynamic range of 0.1 ng/mL to 5 μg/mL and the LOD of 0.03 ng/mL. The sensor exhibited excellent operational stability (<5.5% RSD over 50 cycles), high selectivity against common interferents, and reliable performance in complex matrices (89–114% recovery in serum and agricultural samples). This work not only presents a robust analytical tool for food safety and biological monitoring but also provides new insights into the design of multifunctional heterojunction-based PEC sensors for dual-targets detection.

Photocatalytic conversion of carbon dioxide to value-added chemicals, particularly multi-carbon products, offers a promising route toward carbon-neutral cycles. However, achieving high activity and selectivity remains extremely challenging due to the instability of key reaction intermediates and limited C–C coupling efficiency. Herein, we report a low-coordination manganese single-atom catalyst embedded in zinc sulfide (Mn 1 –ZnS v ) that enables efficient and selective CO 2 -to-C 2+ conversion. In-situ spectroscopic analyses and density functional theory calculations reveal that sulfur vacancies are created at the Mn single-atom coordination sites and induce the formation of coordination-unsaturated Mn-S 2 configuration. The asymmetric coordination environment of Mn modulates local charge distribution, strengthens *CO adsorption, and promotes *CO and *CHO coupling to form the *COCHO intermediate for efficient C–C coupling. As a result, the Mn 1 –ZnS v catalyst achieved 99.1% selectivity for ethylene with a formation rate of 76.6 μmol g -1 h -1 . This study highlights the critical role of atomic-level coordination engineering in advancing photocatalytic CO 2 -to-C 2+ conversion.

Rechargeable magnesium-ion batteries (RMBs) demonstrate notable benefits, including higher theoretical energy density, cost-effectiveness, and improved safety characteristics, positioning them as a viable substitute for conventional energy storage solutions. Nevertheless, the ongoing development of high-performance RMBs continues to face inevitable challenges, such as unsatisfactory practical capacity, inadequate cycle durability, swift energy degradation, and a comparatively limited-service life. Herein, CoS/NiS nanomaterials with cubic-shaped morphology were prepared by a two-step metal sulfide template-free solvothermal synthesis method. The material with internal cavity structure effectively mitigates the large expansion of magnesium-ion battery cathode material due to Mg 2+ embedding during the charging and discharging process, and provides a robustness electrode-electrolyte interface, thus greatly improving the cycle life. Besides, the introduction of Ni elements into CoS materials may form heterojunctions thereby lowering the potential barrier of the conversion reaction and improving the reaction kinetics and redox reversibility. In addition, the abundance of highly electronegative S S bonds in the CoS/NiS material, which also provides many electrochemically active sites and smooth transport paths for the embedding of Mg 2+ , leads to the reduction of its polarization and the improvement of its reaction kinetics, which makes the CoS/NiS as a RMBs cathode material with a high specific capacity and a long cycling life. Thus, this research presents a feasible and effective strategy for enhancing the Mg 2+ storage capability of engineered CoS nanomaterials, with potential applicability and adaptability to other electrode materials.
