Aqueous zinc-ion batteries have emerged as a highly promising energy storage technologies due to their abundant resources, high safety, and environmental friendliness. However, the cycle stability of Aqueous zinc-ion batteries is severely constrained by zinc dendrite growth on the anode and accompanying side reactions in the electrolyte. Mitigating this effect is crucial for the large-scale application of zinc-ion batteries, and separator modification is regarded as an effective strategy to address these challenges. Here, a method of modifying the glass fiber composite separator with amino-functionalized MXene (Ti₃C₂Tₓ) is attempted to alleviate these problems. The modified Ti₃C₂Tₓ was uniformly loaded on the surface of glass fiber separator by vacuum filtration to fabricate the composite separator. Systematic characterization and electrochemical testing revealed that the composite separator with an optimal coating loading of 2 mg cm⁻² significantly enhanced battery performance. The cycle life of Zn//Zn symmetric cells were markedly extended at 5 mA cm⁻², and specifically, reached 250 h at 0.5 mA cm⁻², which is about 8 times longer than that of the unmodified glass fiber separator (~ 30 h). Furthermore, the Zn||MnO₂ all-cell based on this composite separator also exhibited a higher capacity retention rate after 1200 cycles compared to the blank separator group. This provides an effective research direction for the design of high-performance Aqueous zinc-ion batteries separators. Graphical abstract

Conventional polymeric fibrous sponges, as universal passive acoustic control materials, provide a sustainable approach to noise mitigation. However, addressing the narrow effective acoustic bandwidth and inherent flammability remains challenging. Here, a fire-resistant hybrid fibrous sponge (HYFS) featuring broadband acoustic absorption is fabricated by the strategy of spontaneous hollowing and sacrificial template-assisted dynamic hybridization. The hierarchical phase separation within a solution jet enables the concurrent hollowing and three-dimensional self-assembly of ultrafine fibers in one step. Subsequently, a continuous inorganic sheath induced by template sacrifice was generated on the hollow fibers, forming a dynamically evolved multi-scale structural regulatory system, ranging from the microtubular fibers with hollow channels and nanoscale surface roughness to macroscopic fibrous assemblies with open inter-fiber porosity. Thus, the prepared HYFS demonstrates a remarkable noise-reduction coefficient of 0.62 at 270 g/m 2 , along with the broadband sound absorption of effective bandwidth up to 5.5 kHz (sound absorption coefficient > 0.90). Moreover, it demonstrates outstanding fire retardancy with a peak heat release rate of 7 kW/m 2 , representing a 75% reduction compared to the prepared polyimide sponges. This work sheds light on a novel avenue to the scalable fabrication of ultralight, fire-safe, and highly efficient broadband acoustic absorbers for practical applications. Graphical

Organic-inorganic hybrid metal halides have attracted considerable attention due to their structural diversity and promising optoelectronic properties. Although photoluminescence has been observed in hybrid zinc-based halides, the underlying emission mechanisms remain a topic of debate. In this study, we synthesized three phenylethylamine hybrid zinc halides, (C 8 H 12 N) 2 ZnX 4 (X = Cl, Br, I), which feature zero-dimensional (0D) structures consisting of isolated [ZnX 4 ] 2− tetrahedral units surrounded by organic C 8 H 12 N⁺ cations. Upon photoexcitation, these compounds exhibit blue-white emission. Comprehensive experimental analysis suggests that the emission originates from intrinsic lattice defects, specifically zinc interstitials, and radiative transitions from the conduction band to deep-level states. Our findings confirm the presence of defect states in zinc-based halides and reveal that these defects simultaneously act as luminescence centers and limit the overall emission efficiency, contributing to the relatively low photoluminescence quantum yield (PLQY) observed in these materials.

Hydrogel electrolyte based secondary batteries are promising for wearable electronics, yet face challenges including limited mechanical resilience, and narrow temperature range. Herein, we report a robust deep-eutectic hydrogel electrolyte fabricated via synergistic interplay of dual nanophase separation, hydrated eutectic solvation, and hydrogen-bond networks. The interwoven nanophase separation architecture, integrating hydrophilic polyvinyl alcohol phases and hydrophobic polyacrylonitrile phases, realizes high fracture-strength (4.1 MPa) and toughness (13.66 MJ m −3 ). Meanwhile, deep-eutectic chemistry modulates Zn 2+ solvation structures and leverages cyano-coordination channels of polyacrylonitrile to achieve high Zn 2+ ionic conductivity (28.2 mS cm −1 ) and transference number (0.65) at 20 °C. Concurrently, abundant hydrogen bonds induced by multiple donor sites of hydrophilic phases, urethane, and Zn(ClO 4 ) 2 immobilize active H 2 O to ensure broad-temperature durability. This tripartite synergy directs planar Zn deposition along (002) planes and suppresses dendrite growth, enabling Zn||I 2 batteries with a thinner-than-paper thickness (42 μm) and high flexibility. The assembled Zn||I 2 batteries demonstrate high specific energy (108.99 Wh kg −1 ) and cycling stability (over 36,000 cycles under −40 to 80 °C). In this work, the convergence of molecule design, phase modulation, and process engineering establishes a feasible methodological framework for developing advanced flexible batteries that integrate high energy density and harsh environment tolerance.

The design of superionic conductors has been largely focused on static structural features, with the dynamic ion transport mechanism less explored. Here, we explore a paradigm that harnesses the polyanion rotations to trigger the dynamically disordered Li sublattice as well as the liquid-like cation diffusion for superior ionic conductivity in crystals. A descriptor called rotation tolerance factor was proposed as a predictive metric for identifying the potential fast-rotating anion clusters with the low mass and reduced valence charge for given structural frameworks. Guided by this factor, halides with rotational polyanions, namely Li 3 Y(SH) 6 , Li 3 Y(NH 2 ) 6 , Li 2 Zr(NH 2 ) 6 , and an oxide (Li 6.5 La 3 Zr 2 O 11.5 (NH 2 ) 0.5 ) have been designed with synergistic polyanion rotation and Li⁺ sublattice disorder, which lead to enhanced Li ionic conductivities at room temperature compared to the counterparts without polyanions. The experimentally synthesized NH 2 - incorporated Li 2 ZrCl 5.92 (NH 2 ) 0.08 demonstrates a four-fold higher conductivity over Li 2 ZrCl 6 control, enabling all-solid-state Li-In | |LiCoO 2 and Li-In | |LiNi 0.88 Co 0.09 Mn 0.03 O 2 cells with 96.5% and 97.4% capacity retention after 190 cycles at 140 and 200 mA g -1 , respectively. This work provides an insight that flexible anion rotations could promote the dynamically disordered lithium sublattice distribution as well as the ionic conductivity.

Background Colorectal cancer (CRC) remains one of the most commonly diagnosed malignancies worldwide and is associated with high recurrence and poor survival outcomes, particularly in its advanced stages. Zi-Shen-Gu-Sui Decoction (ZSGSD), a traditional Chinese medicinal formula, has been clinically applied in CRC treatment and postoperative rehabilitation; however, its pharmacological mechanisms are not yet fully elucidated. This study aimed to explore the anti-CRC efficacy and molecular mechanisms of ZSGSD, with particular attention to the PI3K/AKT/mTOR signaling axis. Methods UPLC-Q-Orbitrap HRMS was utilized to characterize the chemical profile of ZSGSD. Network pharmacology was employed to identify key signaling pathways and bioactive compounds, and molecular docking was conducted to predict potential interactions between major constituents and PI3K/AKT/mTOR proteins. A xenograft mouse model of CRC was established to evaluate tumor suppression. Histological staining was used to assess apoptosis, and the expression of PI3K, AKT, and mTOR was quantified via RT-qPCR, Western blotting, and immunofluorescence assays. Results Sixty compounds were identified in ZSGSD, with flavonoids comprising approximately 50%. Network analysis suggested potential involvement of the PI3K/AKT/mTOR pathway, and docking results indicated favorable predicted binding between key flavonoids (including Genistein, Apigenin, and Naringenin) and proteins within this pathway. In vivo, ZSGSD treatment suppressed tumor growth in a dose-responsive fashion, with tumor inhibition rates ranging from 30.83% to 75.23% ( p < 0.05). Histological evaluations revealed reduced nuclear-to-cytoplasmic ratios and enhanced apoptotic activity, as confirmed by TUNEL staining ( p < 0.05). Molecular analyses showed a dose-related reduction in PI3K, AKT, and mTOR expression at the transcript and protein levels, indicating that this pathway may be modulated during ZSGSD treatment ( p < 0.05). Conclusion ZSGSD demonstrates notable tumor-suppressive and pro-apoptotic effects in a CRC xenograft model. These outcomes appear to be associated with modulation of the PI3K/AKT/mTOR signaling pathway, although further functional studies are required to confirm pathway specificity and clarify causal mechanisms.

Basic Fuchsin (BF), a recalcitrant organic dye, poses severe risks to aquatic ecosystems and human health, necessitating the development of efficient and stable environmental remediation technologies. Herein, a novel direct S-scheme heterojunction photocatalyst (MG-CQDs/TiO 2 ) was prepared by impregnating and calcining TiO 2 with mango peel-derived carbon quantum dots (MG-CQDs). The successful construction of the S-scheme charge-transfer heterostructure was systematically elucidated through band structure analysis and electron paramagnetic resonance (EPR) spectroscopy. Under ultraviolet–visible (UV–Vis) light irradiation, the MG-CQDs/TiO 2 composite exhibited exceptional photocatalytic performance, achieving a remarkable BF degradation efficiency of 96.5% within 180 min. Notably, its reaction rate constant was 2.1 times higher than that of pristine TiO 2 . Mechanistically, the synergistic interaction between MG-CQDs and TiO 2 significantly promotes the spatial separation of photogenerated carriers. Radical trapping experiments further confirmed that superoxide (·O 2 − ) and hydroxyl (·OH) radicals serve as the primary reactive oxygen species driving the oxidation process. Crucially, density functional theory (DFT) calculations combined with Fukui index analyses provided molecular-level insights into the degradation pathway, identifying the nitrogen atoms and the central carbon of the BF molecule as the preferential sites for radical attack. Furthermore, the composite demonstrated outstanding photostability, maintaining highly efficient degradation over multiple consecutive cycles. Supported by both macroscopic experimental evidence and microscopic theoretical calculations, this study presents a highly efficient, cost-effective, and green paradigm for the advanced treatment of industrial dye wastewater.

Damping materials play a crucial role in mitigating vibrations and minimizing noise pollution across both military and civilian sectors. However, they often encounter the challenge of damping failure under extreme or variable temperature environments due to the narrow glass transition region. Herein, we proposed an innovative strategy by introducing natural phenol (D-α-tocopherol) into the disulfide-based polyurethane elastomer (PUE), which exhibited ultra-wide effective damping temperature range (–53 ~ 118 ℃), large Tan δ area (77 K) and excellent self-healing properties compared with reported PUE composites. Interestingly, D-α-Tocopherol possesses molecular structure resembling tadpoles with abdominal suckers and flexible tails, which facilitated the formation of intermolecular hydrogen bonds and dangling chains in the PUE. The intermolecular hydrogen bond promoted the phase separation of the soft and hard segments in PUE, thus forming ultra-wide glass transition regions. Meanwhile, the dangling chain effectively increased the free volume between the PUE chains, facilitating the movement of the PUE chain and further accelerating the breaking and recombination of hydrogen and disulfide bonds. The introduction of D-α-Tocopherol increased the energy-loss pathways and significantly enhanced the damping performance of the PUE composites from low to high temperature. This work provides a novel strategy for designing high-performance damping materials.

While increasing dietary calcium (Ca) intake can reduce the oral bioavailability of heavy metal(loid)s, it remains unclear whether a series of Ca compounds can simultaneously reduce the oral bioavailability of As and Pb from soil. The influence of eight Ca compounds on As and Pb bioaccessibility in soils was determined using an in vitro gastrointestinal model, following which an in vivo bioassay was used to determine the most effective Ca compounds on As and Pb bioavailability. The results showed that, while CaHPO 4 was the most effective in reducing Pb bioaccessibility in gastric (from 19.0 to 92.3% to 14.3‒66.4%) and intestinal (from 0.18 to 17.5% to 0.00‒3.53%) phases, it conversely exhibited the strongest capacity to enhance As bioaccessibility. However, the addition of Ca acetate reduced the Pb bioaccessibility in the gastric phase and As bioaccessibility in the intestinal phase. More importantly, the Ca acetate (~ 200 mg Ca kg -1 ) was the most effective in reducing relative bioavailability of As and Pb based on mouse bioassay. Our finding verify the efficacy of Ca acetate in mitigating the oral bioavailability of As and Pb. This study lays a theoretical foundation for the targeted use of optimal Ca compounds to mitigate human exposure risks to environmental As and Pb.

Innovative cloud algorithms-assisted portable Zn-based fluorescent sensor arrays (ZnMOF-74 and Mn:ZnS QDs) are proposed for rapid, sensitive and on-site detection of four antibiotics, enrofloxacin (ENX), chlortetracycline (CTC), oxytetracycline (OTC) and tetracycline (TC). This sensor arrays for the first time utilize the Lewis acid-base regulation of ZnMOF-74 and the crystal field effect of Mn:ZnS QDs to generate characteristic fluorescent “fingerprints” for the four antibiotics. Through the optimization of various chemometric algorithms (PCA-LDA, PLS-DA, KNN and RF), the recognition accuracy of four antibiotics in the complex matrix reached 98%. Moreover, a homemade smartphone APP based on cloud machine learning algorithms was developed, enabling rapid and accurate multiplexed detection with LODs of 8.9 nmol/L, 4.1 nmol/L, 5.7 nmol/L, and 6.7 nmol/L for ENX, CTC, OTC, and TC, respectively. The corresponding limits of quantification (LOQs) were 26.7 nmol/L, 12.3 nmol/L, 17.1 nmol/L, and 20.1 nmol/L, respectively. The proposed method was successfully applied to the detection of antibiotics in milk, honey, and beef samples, with satisfactory recoveries ranging from 97.33% to 107.40% and relative standard deviations (RSDs) below 5.63%, indicating good accuracy and reliability for real sample analysis. This work demonstrates the immense potential for universal, high-throughput, and accurate multi-target detection, providing transformative solutions in food safety.
