Circularly polarized luminescence (CPL) materials are highly sought after for their unique chiroptical properties, but their rational design remains challenging. To address this, a machine learning (ML) platform that intelligently screens deep eutectic solvents (DES) for crafting G-quartet-based gels with tailored CPL is established. An ML classifier trained on experimental data predicts CPL activity with 0.916 accuracy. SHapley Additive exPlanations (SHAP) analysis identifies key DES molecular descriptors, guiding the discovery of novel materials that exhibit a record-high luminescence dissymmetry factor (g lum ) of 0.222 for nucleotide-based systems and achieve chirality inversion via DES modulation. The Sure Independence Screening and Sparsifying Operator (SISSO) algorithm further yields interpretable design formulas. Leveraging the distinct polarization of these gels, we demonstrate a fourth-level anti-counterfeiting strategy, decrypting concealed information via Morse and ASCII codes to enhance information security. This ML-driven methodology accelerates the discovery of high-performance CPL materials and opens new design avenues.

The development of efficient and cost-effective electrocatalysts is critical for advancing durable water-splitting systems. Special attention must be given to catalyst design, functionality, and interface regulation strategy to create synergistic effects that enhance electrocatalytic performance. We present a rational design of non-precious optimized heterojunction electrocatalysts comprising face-centered cubic nickel metal, cubic Ni₃S₄, and hexagonal NiS phases, supported on a 3D cross-linked carbon nanofiber (CNF) network. Detailed characterization reveals lattice-matching heterojunctions between Ni₃S₄, NiS, and Ni, where strong C-S bonding stabilizes the heterojunction and ensures effective electronic coupling. These heterogeneous interfaces serve as highly electroactive regions, significantly enhancing charge transfer, structural stability, and reaction kinetics. The optimized Ni₃S₄/NiS/Ni@CNF composite demonstrates exceptional bifunctional performance, achieving a low hydrogen evolution reaction overpotential of 88 mV at 10 mA/cm² with a Tafel slope of 34 mV/dec and an oxygen evolution reaction overpotential of 330 mV at 10 mA/cm² with a Tafel slope of 45 mV/dec, alongside excellent durability. The superior electrocatalytic performance is attributed to synergistic interactions at the Ni₃S₄, NiS, Ni, and CNF heterointerfaces, enhanced electronic conductivity, increased catalytic site exposure, and efficient interfacial charge transfer. This work offers a new strategy for the rational design of heterojunction-based materials with superior electrochemical performance in water-splitting applications.

In seawater electrolysis, the presence of Cl − ions corrodes the electrode and causes side reactions, severely degrading OER efficiency and stability. To address these challenges, we developed a crystalline-amorphous heterointerface to enhance their OER activity and stability. The synergistic coupling of crystalline and amorphous phases creates optimal sites for superior catalytic activity. In addition to the robust performance, partial leaching of the amorphous CoS x phase forms a protective sulfate layer and triggers surface reconstruction. This rich passivated layer of OH − creates an alkaline environment near the electrode surface that repels Cl − electrostatically. Therefore, the optimum NiMn 2 O 4 /CoS x catalyst indicates an ultralow overpotential of 220 and 255 mV at 100 mA cm −2 and robust performance of 700 h and 300 h at 500 mA cm −2 in alkaline and seawater conditions. This work provides a blueprint for developing highly effective and stable catalysts for clean energy production.

Simultaneously harnessing photogenerated electrons for water splitting (to produce H 2 ) and holes for benzyl alcohol oxidation (to synthesize high-value chemicals) offers a promising strategy to address the energy crisis. However, charge rapid carrier recombination and weak H 2 O adsorption capacity severely limit the efficiency of this approach. Herein, we employ electrostatic self-assembly to construct a CdS/Bi 2 S 3 composite photocatalyst featuring an S-scheme electron migration pathway and a robust built-in electric field (BEF). This work demonstrates that the strong BEF of the CdS/Bi 2 S 3 composite photocatalyst significantly enhances the chemisorption capacity of H 2 O molecules and the carrier separation efficiency. The optimal CdS/Bi 2 S 3 -3 composite achieves H 2 and benzaldehyde production rates of 17.9 and 16.1 mmol g −1 h −1 , respectively. Comprehensive characterization and theoretical calculations elucidate the mechanisms underlying the S-scheme electron transfer pathway and the formation of the BEF. This study offers a new perspective for designing photocatalytic systems that simultaneously utilizing photogenerated electrons and holes.

Ideal electrolytes for low-temperature-resistant aqueous zinc-ion batteries should promote rapid ion desolvation while stabilizing interfacial reactions. Existing research generally introduces additive molecules for optimizing local coordination environment to inhibit H 2 O crystallization; the strong hydrogen bond (HB) effect between co-solvents still exists, and uncoordinated polar groups act as acceptors/donors to induce uneven group coordination and the formation of new strong HB networks. Herein, we propose an electrolyte design strategy with a coordination-induced mechanism to address the long-standing challenges of slow low-temperature kinetics and irregular dendrites in aqueous zinc-ion batteries. By introducing low-carbon polyols to optimize the global solvation structure, low-temperature ice crystallization through intramolecular strain is mitigated, promoting the interaction between non-coordinating solvents to shift from strong HB (O-H:O*, 30 kJ/mol) to weak HB (C-H:O*, 5 kJ/mol), which enables dynamic salt-water-organic cosolvent ternary interaction, promoting rapid Zn 2+ reaction kinetics and stabilizing interfacial reactions. Both experimental and theoretical analyses confirm the effectiveness of the present strategy, which enables low-carbon-polyol-based electrolyte to exhibit a high capacity of 65.13 mAh/g at −25 °C (1 A/g) and a capacity retention of ~95% after 600 cycles.

The coexistence of antibiotic and nitrogen/ phosphorus nutrient pollutants in mariculture wastewater presents a considerable challenge for their simultaneous remediation. In this study, a novel photocatalytic-Mg metal-coupled fuel cell (PMFC) system based on Mg anode and Co/MoS 2 /CC photocathode was developed to achieve dual-circuit energy conversion and antibiotic and nitrogen/ phosphorus simultaneous removal. Under simulated marine conditions, the PMFC system achieved 93.34% removal of norfloxacin (NOR), which was higher than that of the photocatalytic fuel cell (PFC) system (67.66%). Meanwhile, almost all PO 4 3− and 43.28% NH 4 + were removed via struvite precipitation and direct ammonia oxidation, while delivering a maximum power density of 7.62 mW/cm 2 . Mechanistic investigations, combining density functional theory (DFT) calculations, X-ray photoelectron spectroscopy (XPS), and photoelectrochemical measurements, revealed that exogenous electrons from the Mg anode enhance the separation and transport efficiency of photogenerated carriers. Co sites of the cathode served as electron accumulation centers, concurrently capturing photogenerated and exogenous electrons. A synergistic effect between the exogenous electron and the regulation of the cathode's electronic structure by Co-modification enhanced power generation, while reducing the oxygen reduction overpotential of the cathode. Radical quenching experiments demonstrated that Cl − was effectively activated through chain reaction, leading to the dominant active species controlling NOR degradation shift from •OH and • O 2 − to ClO• and • O 2 − . This study integrated pollution control, electricity generation, and resource circulation in mariculture wastewater, providing an efficient solution for the sustainable development of industry.

High-temperature and high-salinity (HTHS) bottom-water gas reservoirs are prone to rapid gas–water contact rise and severe water coning, resulting in early water breakthrough and low gas recovery. However, the long-term stability and selective plugging performance of conventional polymer gel systems are severely compromised under such harsh conditions. In this study, a high-stability polymer gel system was formulated for selective water shutoff in HTHS bottom-water gas reservoirs. The system consists of PM134 (PM-5) polymer crosslinked with polyethyleneimine (CA-6), with thiourea (AD-1) and nano-SiO₂ (AD-5) incorporated as stabilizing and reinforcing additives. Under simulated reservoir conditions (110°C and salinity of 16 × 10⁴ mg/L), the gel exhibited a controllable gelation time of 2.5–3.5 days and achieved a high gel strength (Grade H). Long-term aging tests demonstrated excellent stability, with the gel maintaining at least Grade G strength and a syneresis ratio below 10% after 60 days. Rheological measurements indicated predominantly elastic behavior (G′ > G″) throughout the aging period, confirming the integrity of the gel network under HTHS conditions. The incorporation of thiourea (AD-1) effectively inhibited thermal–oxidative degradation, while nano-SiO₂ (AD-5) reinforced the three-dimensional gel structure. Core flooding experiments revealed strong selective plugging performance, with water-phase plugging efficiency exceeding 95% and gas-phase plugging efficiency remaining below 35%. Gel treatment significantly delayed water breakthrough, increased the breakthrough pressure from 6 MPa to 13 MPa, and enhanced ultimate gas recovery by 12.84%. These results demonstrate that the proposed gel system provides a reliable and effective solution for selective water shutoff in HTHS bottom-water gas reservoirs, offering strong potential for field application under extreme reservoir conditions.

Nickel sulfide (NiS) offers immense promise as a sodium-ion battery (SIB) anode with its high theoretical capacity, metallic conductivity, and rich redox chemistry, yet its potential is crippled by violent volume fluctuations, sluggish Na + kinetics and polysulfide shuttling. Here, we architect a defect-rich, nitrogen-doped three-dimensional (3D) hollow coral-like carbon scaffold encapsulating NiS nanocrystals (NiS@N-HCC) via a scalable precursor-pyrolysis strategy. The tailored interfacial electronic coupling between NiS and the N-doped carbon realigns charge density and unleashes intrinsic conductivity, while polar defect sites act as powerful chemical anchors to immobilize polysulfides and eradicate shuttle loss. Encasing it all, the conductive hollow network brims with high-affinity Na + docking sites, channels ions through compressed diffusion corridors and absorbs drastic volume surges without fracture. As a result, NiS@N-HCC delivers 410.8 mAh g −1 after 1000 cycles at 1 A g −1 (92.5% retention), 357.5 mAh g −1 at 15 A g −1 , and only 0.003% decay per cycle over 3000 cycles at 10 A g −1 . Full cells with Na 3 V 2 (PO 4 ) 3 @C cathodes reach an energy density of 149.4 Wh kg −1 and a peak power density of 1572.9 W kg −1 , maintaining 82.1% capacity retention over 1600 cycles, while pouch-type devices sustain bright, stable high-power output, propelling NiS@N-HCC to the forefront of next-generation, high-power, long-life sodium-ion energy storage.

Charge carrier recombination represents a fundamental constraint in semiconductor photocatalysis. Combining heterostructure design with deliberate defect engineering to facilitate hydrogen intermediate (*H) adsorption is a viable strategy for boosting photocatalytic hydrogen evolution reaction (HER). Herein, we design defective MBene via controlled etching and perform in situ hydrothermal assembly to develop a tailored MoBT x /CdS heterostructure. Incorporating a mere 0.5 wt % two-dimensional MoBT x MBene leads to a fourfold enhancement in HER activity over bare CdS. The established MoBT x /CdS catalyst achieves a remarkable HER of 10.2 millimoles per gram per hour under ambient conditions with 23.2% apparent quantum yield and sustains 90.2% activity after 24 hours of continued operation. Outstanding environmental adaptability is demonstrated through a consistent HER value of 7.1 millimoles per gram per hour in tap water and 5.7 millimoles per gram per hour in seawater. The temperature-dependent performance demonstrates notable robustness, reaching 11.1 millimoles per gram per hour at 35°C while preserving 40% functionality at harsh 5°C. Integrated photoelectrochemical and computational analyses elucidate that Mo vacancies create band alignment–optimizing electron traps and reduced *H adsorption barriers, enhancing fast carrier separation. Concurrently, interfacial covalent Mo─S bonds establish atomic-level charge-transfer pathways and enable rapid electron migration. This work establishes a previously unidentified paradigm for advanced photocatalyst design through concerted defect-interface modulation.

Exosomes, despite their promise as drug carriers for crossing biological barriers, remain underexplored for noninvasive posterior ocular delivery. Here, we demonstrate that semen-derived exosomes (SEVs) penetrate ocular barriers effectively, owing to their epidermal growth factor expression, which mediates reversible tight-junction disruption. SEVs reach the posterior segment via dual corneal and conjunctival routes. Using this, we engineered FA-SEVs@CMG eye drops, where SEVs are modified with folic acid (FA) and loaded with a nanozyme system (CMG) composed of carbon dots, manganese dioxide, and glucose oxidase. This eye drop leverages SEVs’ excellent penetration ability and FA’s targeting effect to enhance drug delivery to retinoblastoma (RB) cells. Internalized CMG induces intense oxidative stress, disrupts the autophagy-apoptosis balance, and triggers RB cell self-destruction. In vivo, FA-SEVs@CMG effectively inhibits RB growth while preserving retinal function. This work establishes the first SEV-based platform for noninvasive posterior segment delivery, offering a transformative strategy for treating posterior ocular diseases.

Two-dimensional tin sulfide (SnS 2 ) shows great promise as a NO 2 gas-sensing material due to its large specific surface area and suitable band structure, yet its selectivity and detection limit remain inadequate. Herein, PdS/SnS 2 composite with PdS nanoparticle inlaid in lettuce-like structure SnS 2 was synthesized via a facile microwave-assisted method for room-temperature NO 2 detection. The optimized PdS/SnS 2 composite exhibits that the response value to 5 ppm NO 2 reached 2560% at room temperature under 50% relative humidity, which is approximately 10.7 times that of pristine SnS 2 (238%). Importantly, its experimental limit of detection (LOD) for NO 2 is as low as 800 ppt, while the theoretical LOD is below 164 ppt. Furthermore, it also shows outstanding reversibility and repeatability (RSD < 5%), and high selectivity (response ratio > 40) against interfering gases. The enhanced sensing performance is attributed to the synergistic effect of the PdS/SnS 2 heterojunction and sulfur vacancies, which promotes NO 2 gas adsorption on the material surface and electron transport inside the material. This study provides a feasible strategy for designing high-precision and ultra-trace NO 2 sensors with ppt-level detection capabilities at room temperature.

Hydrogen production via photocatalytic water splitting is an essential technology for renewable energy conversion, but its real-world application is restricted by insufficient carrier separation efficiency and compromised stability of semiconductor-based catalytic materials. In this study, we address these challenges by designing a sandwich-like Cd 0.3 Zn 0.7 S@Ti 3 C 2 MXene Schottky junction catalyst. First, we precisely tuned the molar ratio of Zn/Cd precursors to synthesize Cd x Zn 1-x S solid solutions, and found that Cd 0.3 Zn 0.7 S nanosheets exhibited the optimal photocatalytic hydrogen evolution rate, due to its harmonious absorption of visible light and optimized band structure. Next, multilayer Ti 3 C 2 MXene nanosheets were prepared via hydrofluoric acid (HF)-assisted etching of Ti 3 AlC 2 MAX phase, and then composited with Cd x Zn 1-x S precursor to form the Cd 0.3 Zn 0.7 S@Ti 3 C 2 heterojunction. When the loading capacity of Ti 3 C 2 MXene is optimized, the composite exhibits a maximum hydrogen production rate of 9.4 mmol·h −1 ·g −1 , representing a 2.5-fold enhancement compared to pristine Cd 0.3 Zn 0.7 S and a 7.5-fold enhancement compared to pristine Ti 3 C 2 MXene. The Cd 0.3 Zn 0.7 S@Ti 3 C 2 exhibits excellent photocatalytic performance, primarily attributed to its unique sandwich structure and the Schottky junction. Which significantly enhances charge separation efficiency, and effectively suppresses the photocorrosion of Cd 0.3 Zn 0.7 S and ensures superior photochemical stability.This study provides a novel approach for the development of high-performance photocatalysts for water splitting.
