The photothermal catalytic reduction of CO 2 to synthesize high-value hydrocarbon fuels has attracted significant attention. However, current conversion efficiency remains constrained by the dual limitations of insufficient photogenerated carrier concentration and the difficulty in effectively adsorbing and activating CO 2 . This work first successfully synthesized g-C 3 N 4 nanohollow spheres using a hard template method and ultrathin Bi 2 MoO 6 nanosheets via a solvothermal method, and then fabricated an S-scheme heterojunction by electrostatic assembly. Crucially, during the photothermal catalytic reaction, the dynamic formation of photogenerated oxygen vacancies and their induced dipole-limited domain field (DLDF) structure were identified as the key mechanism driving the exceptionally high activity in CO 2 photoreduction. In situ electron paramagnetic resonance spectroscopy directly demonstrated the dynamic cycling of the photogenerated oxygen vacancies during the catalytic reaction. Density functional theory calculations and carrier dynamics characterization analysis confirmed the synergistic effect of the DLDF in optimizing carrier kinetics and enhancing CO 2 adsorption. Ultimately, a high CO production rate of 48.69 μmol·g −1 ·h −1 was achieved. This work integrates heterojunction construction and morphology control strategies to achieve synergistic enhancement of photothermal catalytic performance and elucidates the intrinsic mechanism for the activity improvement. It provides an effective way for developing efficient heterojunctions for photothermal catalytic CO 2 reduction.

Development of efficient artificial light-driven ion pumps is crucial for solar energy harvesting, yet remains fundamentally constrained by severe carrier recombination in photoactive materials. To overcome this fundamental limitation, we design a carbon nitride-carbon nanotube composite membrane that utilizes an interfacial Schottky junction for enhanced charge separation. The charge-regulating behavior of Schottky junctions effectively inhibits photoinduced charge recombination, thereby augmenting charge density asymmetry across the membrane. The resulting robust built-in electric field significantly amplifies light-driven force beyond single-component systems. Under 200 mW cm–2 illumination, the composite membrane demonstrates exceptional ion pumping performance, enabling reverse ion transport against a 2000-fold concentration gradient. Compared to homogeneous carbon nitride membranes, it exhibits a 233% enhancement in gradient tolerance and a 293% increase in power output. This work presents a Schottky junction engineering strategy for high-performance light-driven ion pumps, paving the way for advanced solar energy conversion and optoelectronic applications.

In order to enhance the CO 2 capture performance of ionic liquids, this work synthesized porous ionic liquids (pILs) utilizing UiO-66 as the porous material and [DMIM][NTf 2 ] as a sterically hindered solvent. By controlling the MOF proportion within a low range (<2.0%), the pILs achieved a dual enhancement in both CO 2 solubility and diffusion coefficient. Comprehensive characterization confirmed the structural integrity, well-defined morphology, and correct chemical composition of the synthesized materials. The CO 2 solubility in the low-pressure region was measured by the isochoric saturation method, and the corresponding diffusion coefficients were calculated based on the semi-infinite volume model. The results demonstrated that the pILs achieved dual enhancement in both CO 2 solubility and diffusion coefficient exhibiting an increase of approximately 20% for both parameters. And the absorption-desorption experiment further showed an enhancement in CO 2 solubility, with over 94% cyclic efficiency after five cycles for the three representative absorption pressure. These results indicate the significant enhancement and exceptional absorption stability of pILs across a wide pressure range. The dual enhancement effect demonstrates the exceptional CO 2 capture performance offering important insights for the practical industrial application.

Phenolic impregnated carbon ablator (PICA) is a lightweight ablative material extensively used in thermal protection systems. However, its performance is limited by the poor oxidation resistance of carbon fibers and the insufficient thermal stability of the phenolic matrix at elevated temperatures. To address these challenges, a Si–Zr binary-modified carbon fiber-reinforced phenolic aerogel composite (denoted as S a Z b -CF/PA) was fabricated via a two-step sol–gel process. A SiO 2 –ZrO 2 ceramic coating was formed in situ on the fiber surface, serving as an effective barrier against oxygen diffusion. The resulting composite exhibits a low density (∼0.70 g/cm 3 ), high compressive strength, and excellent oxidation and ablation resistance. After exposure to air at 1000 °C, S a Z b -CF/PA retained 47.5 wt% of its mass, whereas the unmodified composite retained only 2 wt%. Under oxyacetylene flame testing (2 MW/m 2 for 60 s), the composite demonstrated low linear and mass ablation rates of 0.0160 mm/s and 0.0048 g/s, respectively. Microstructural analysis revealed the formation of a dense and continuous SiO 2 –ZrO 2 -rich ceramic layer that effectively protects the underlying structure during ablation. These results indicate that fiber-level ceramic modification via sol–gel coating is a promising strategy for developing high-performance lightweight ablative composites for extreme thermal environments.

Polyurethane (PU) adhesives hold significant promise for interfacial applications due to their tunable soft-hard segment design. However, the sustainability of conventional PU adhesives is constrained by their reliance on petroleum-derived feedstock, while their adhesion strength is significantly undermined in humid or underwater environments due to competitive interfacial water. Herein, we report a two-step strategy that integrates the glycolysis of waste polyethylene terephthalate (PET) with bio-inspired dopamine grafting to fabricate a catechol-functionalized polyurethane adhesive with robust and repeatable wet adhesion. Waste PET was first glycolyzed and the product was purified via silica gel column chromatography. The resulting glycolytic liquid product (GLP) was employed as a chain extender. Dopamine was then grafted onto the PET-based polyurethane backbone to introduce catechol functionalities, yielding a dopamine-grafted adhesive (C-GPUD). The catechol groups not only interact with urethane groups via hydrogen bonding but also undergo conformational adaptation, oxidative cross-linking, and metal chelation. These synergistic effects collectively enhance both the cohesive strength and the interfacial bonding. The optimized C-GPUD 10 adhesive exhibited rapid and robust adhesion on various substrates in underwater scenarios. It demonstrated excellent repeatable adhesion in tap water, retaining a lap shear strength of 0.21 MPa after ten peeling cycles, which corresponds to 45.7% retention of the initial strength. This outstanding performance enables C-GPUD to effectively seal liquid and gas leaks, demonstrating considerable potential for applications in emergency sealing and underwater repair.

An U-shaped fiber long range surface plasmon resonance (LRSPR) sensor is proposed to detect trace Hg2+ in water system. The U-shaped fiber is bend and coated with 100 nm MgF2 and 50 nm Au film, the U-shaped fiber LRSPR senor could combine the advantage of high sensitivity and low full width of half maximum (FWHM) by the optimization of the fiber bending radius (BR) and MgF2 thickness. With the functionalization of single-stranded DNA (ssDNA) on the Au layer by covalent bond, the Hg2+ could be selectively detected by the thymine (T) base pairs, which would form stable T-Hg-T structure by the folding of ssDNA and cause the change in surface refractive index (RI). The detection range of Hg2+ is 50 nM-5 mM, and the limit of detection (LOD) reaches at 60 nM. The selectivity and stability are proved to be good and the recovery from the spiked tap water is also tested. The good performance and wide range of the proposed sensor indicates high potential for future Hg2+ sensor development and multiple using scenarios.

Silicon-based materials possess a theoretical specific capacity of 4200 mAh g −1 , making them an ideal anode material for current high-energy-density lithium-ion batteries. However, their significant volume expansion (>300%) and inherently poor electrical conductivity limit their large-scale application. In this study, an innovative synergistic design approach was employed to propose a nickel (Ni)-doped hollow carbon-coated silicon composite material (Ni/HSi@C). This material integrates structural engineering with a carbon layer coating the hollow silicon structure, thereby facilitating volume changes toward internal expansion. Additionally, phase state regulation and interface optimization were integrated, with Ni-doping introduced to promote the formation of amorphous silicon while inducing the formation of a stable solid electrolyte interface film rich in LiF during charge–discharge cycles, thereby achieving synergistic optimization. Experimental results indicate that after 1000 cycles at a current density of 1000 mA g −1 , the specific capacity of Ni/HSi@C remains at 1318 mAh g −1 . Furthermore, the pouch cell achieves an energy density of 379 Wh kg −1 . In situ impedance and distribution of relaxation times analysis demonstrate that Ni-doping significantly reduces interfacial impedance and suppresses electrolyte decomposition.

Aqueous zinc-ion batteries (AZIBs) are promising for energy storage. However, Zn anode instability—caused by dendrite growth, hydrogen evolution reaction (HER), and by-product formation—limits their practical viability. HER, in particular, accelerates Zn consumption, disrupts electrode integrity, and induces local alkalization, exacerbating passivation. Conventional strategies emphasize electrolyte formulation and surface passivation, yet few address the underlying electronic origin of HER on Zn. Here we report a catalysis-inspired strategy that electronically modulates Zn reactivity via d-band center engineering to intrinsically suppress HER. By introducing oxalic acid (OA) as a molecular additive, we achieve a significant downward shift in the Zn d-band center (from –6.896 to –7.062 eV), weakening hydrogen adsorption and fundamentally reducing HER activity. In parallel, OA disrupts the Zn 2+ solvation structure by displacing coordinated SO2– 4 anions, suppressing interfacial by-product formation. These dual effects yield unprecedented performance: Zn||Zn symmetric cells operate stably for over 3500 h; Zn||Cu cells exhibit 99.41% Coulombic efficiency over 1500 cycles; and Zn||I 2 cell retain 92.8% capacity after 10,000 cycles; the 1.3 Ah Zn||I 2 pouch cell presents good cyclability. This work pioneers a surface electronic tuning paradigm in battery design, extending catalytic d-band theory to electrochemical interfaces for HER suppression and interfacial stabilization in aqueous metal batteries.

The low-carbon utilization of carbonated municipal solid waste incineration fly ash (MSWI FA) as a cementitious material represents a promising strategy for achieving both harmless disposal and resource recovery. However, the occurrence and transformation mechanisms of heavy metals within cementitious systems remain poorly understood, constraining their environmental safety and long-term stability. In this study, ultrasonic-assisted carbonation was employed to pretreat FA, enhancing dechlorination, carbonation, and dealkalization, thereby reconstructing its mineral composition and chemical environment. The ultrasonically carbonated FA (UFA) was subsequently incorporated into cement paste. pH-dependent leaching experiments combined with geochemical modeling elucidated the mineral phase transformations of major and trace elements in RFA, UFA, and FA-blended systems. In UFA-cementitious systems, ultrasonic carbonation reduced the alkalinity and ionic strength of FA, stabilized Ca and Mg as carbonate phases, transformed sulfur from gypsum to ettringite (AFt), and promoted the synergistic formation and densification of C-S-A-H gels and AFt phases. Anionic elements (As, Cr) were immobilized through adsorption on Fe oxides, complexation with organic ligands, and lattice substitution within AFt, while cationic metals (Cd, Pb, Zn, Cu) were stabilized via the formation of insoluble carbonates and hydroxides, as well as encapsulation within C-S-A-H gels. Through these synergistic mechanisms, heavy metal solubility was markedly suppressed over the pH range of 6–13, thereby maintaining the OPTI of UFA and cementitious matrices at a Low-risk level. This study reveals the elemental stabilization mechanisms involved in ultrasonic carbonation and hydration-gelation processes in FA, underpinning the improved environmental stability of FA-derived cementitious systems.

Controllable wetting of liquid on solid surface is meaningful for advanced science and engineering. Current researches about controllable liquid spreading are generally limited to unidirectional modes, while achieving multi-directional spreading on microstructured surfaces remains challenging. Herein, we propose a novel type of bulk-cusp microstructure, exhibiting 0 to 4-directional spreading of droplet without external energy input. This behavior occurs not only under single-drop deposition but also under continuous liquid injection. The bulk structure is assumed to have cross or square shape, implying relatively high and low coverage ratio of the precursor film, respectively. Owing to the drag effect of the precursor film, the cross-cusp microstructure facilitates controllable spreading of the main droplet, whereas the square-cusp microstructure just has guidance action on precursor film due to its low coverage ratio. Mechanism analysis reveals the capillary forces generated from the narrow gaps between adjacent cusps effectively separate the precursor film. The area coverage ratio of precursor film determined by the shape of the bulk influences the coupling or decoupling of the droplet body and precursor film. Such controllable multi-directional liquid spreading enables applications in lubrication enhancement and smart evaporation cooling.

As emerging environmental contaminants with suspected human health impacts, benzotriazole ultraviolet stabilizers (BUVSs) lack empirical evidence regarding pulmonary carcinogenicity in exposed populations, highlighting the need to investigate their potential association with lung cancer. This study aimed to analyze the relationship between urinary BUVSs concentrations and lung cancer risk within the general population of Hangzhou, China. This case-control study included 397 newly diagnosed lung cancer patients and an equivalent cohort of age- and sex-matched healthy controls. Urine samples were analyzed for five different types of BUVSs, with total concentrations ranging from 0.46 to 36.40 μg/g creatinine. 2-(2’-Hydroxy-3’,5’-di-tert-butylphenyl)-5-chloro-benzotriazole (UV-327) was the most prevalent, with a mean concentration of 5.09 μg/g creatinine. Logistic regression models were employed to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for assessing lung cancer risk in relation to urinary BUVSs concentrations. Following adjustment for covariates including sex, smoking status, alcohol intake, and dietary habits, urinary 2-(2H-benzotriazol-2-yl)- p -cresol (UV-P) was the only BUVS demonstrating a significant correlation with lung cancer risk. Participants in the highest urinary UV-P concentration group exhibited a 4.5-fold higher risk of lung cancer relative to those in the lowest group (adjusted OR=4.55, 95% CI:2.84–7.28, p for trend < 0.01). The link between elevated UV-P exposure and a higher risk of lung cancer was affected by factors such as smoking status and dietary habits. These findings provide novel evidence of a potential association between BUVSs exposure—particularly UV-P—and lung cancer in the general Chinese population, and highlight the need for future longitudinal and mechanistic studies to confirm these associations and elucidate the underlying biological pathways.
