Aqueous zinc-iodine batteries (AZIBs) show promise for grid-scale energy storage, but they are hampered by polyiodide shuttling, sluggish iodine redox kinetics, and irreversible active-site poisoning caused by uncontrolled adsorption. We provide a comprehensive screening of M 1 (M 1 = P, S, B) heteroatom dopants, and P is identified as the best candidate for achieving coordination-tuned, moderate adsorption that balances adsorption and catalytic activity while mitigating site poisoning. Using phytic acid as both the P source and an etchant, we create a universal in situ approach to core–shell single-atom catalysts (M 2 -P-CSNC, M 2 = Fe, Co, Ni). The unique core–shell structure achieves stable confinement of polyiodides, rapid ion transport, and protection of active sites, while in situ P doping precisely regulates the local electronic environment and d -band center of the Fe–N x active centers. In situ characterization confirms that Fe–P-CSNC has a strong reversible anchoring ability for polyiodides, which can significantly accelerate redox kinetics. The optimized Fe–P-CSNC/I 2 exhibits almost no capacity decay after 20,000 cycles at a current density of 2 A g −1 . This work’s facile heteroatom doping strategy for electronic modulation offers a reference for high-performance catalyst design in conversion-type energy storage systems.

Elevated CO 2 (eCO 2 ) and arbuscular mycorrhizal fungi (AMF) positively influence plant defense under heavy metal exposure individually, however, the combination of them and the contribution of eCO 2 were still unclear. The pot experiment was employed to explore the combined effect of eCO 2 (700 ppm) and Funneliformis mosseae on the defense of black locust ( Robinia pseudoacacia L.) grown in cadmium (Cd)-polluted soils by 13 C isotope tracer. Elevated CO 2 significantly caused an increase in Cd content, decreases in contents of malonaldehyde, carotenoids, soluble sugars and proteins, metallothioneins (MTs) and proline and activities of superoxide dismutase, catalase, peroxidase, ascorbate peroxidase and glutathione peroxidase and increases in ascorbic acid (AsA), glutathione (GSH), cysteine (Cys) and phytochelatins (PCs) in leaves under F. mosseae colonization. Additionally, the indirect contributions of eCO 2 to AsA, GSH, Car, proline, soluble sugars and proteins, Cys, PCs and MTs under eCO 2 + F. mosseae were lower than that under eCO 2 alone. Overall, eCO 2 enhanced the defense of black locust colonized by F. mosseae under Cd exposure by stimulating AsA, GSH, PCs and Cys synthesis, which will provide some insights into the effect of global change on the resistance mechanism of plants colonized by AMF to heavy metals.

This study evaluated thermosonication combined with germinants and licorice extract (GTL) in the “germination–inactivation–inhibition” strategy to control spore contamination and preserve the quality of ready-to-eat (RTE) chicken breasts. The microbial counts, color, pH, texture, lipid oxidation, and volatile profile of RTE chicken breasts were assessed. The result demonstrated that the GTL treatment significantly reduced the total viable counts (TVC) and Clostridium counts, with TVC remaining below 4 log CFU/g and Clostridium counts lower than in the control (4.42 vs. 7.31 log CFU/g) by day 6 ( p < 0.05). The approach effectively mitigated the changes in color, texture, and moisture distribution, and postponed the increase in pH, lipid oxidation, and volatile nitrogen accumulation in RTE chicken breasts. In addition, a total of 51 volatile compounds were detected by gas chromatography–ion mobility spectrometry (GC-IMS). Results from the E-nose and GC-IMS showed that GTL treatment preserved a more stable volatile profile than high-temperature sterilization, including esters (e.g., 2-methylpropyl acetate), alcohols (e.g., 4-methyl-2-pentanol-D), aldehydes (e.g., 2-methylpropanal), and furans (e.g., 2-ethylfuran-D). These findings demonstrate that GTL is a promising approach for reducing microbial contamination and maintaining the edible quality of RTE chicken breasts under accelerated storage conditions.

Although the construction of semiconductor/transition-metal oxyhydroxide (SC/TMOOH) system represents a promising approach for boosting photoelectrochemical (PEC) water splitting performance, persistent challenges including inevitable interface charge recombination and sluggish water oxidation kinetics continue to hinder the improvement of PEC performance. Here, a rational ligand modulation strategy is developed to optimize the PEC activity of SC/TMOOH system through coordinating 2-methylimidazole (2MI). As a result, BiVO 4 /FeOOH-2MI achieves unprecedented PEC efficiency, exhibiting an outstandingly high photocurrent density of 6.57 mA/cm 2 at 1.23 V vs. reversible hydrogen electrode (RHE) along with long-term durability. Density functional theory (DFT) in combination with in situ ultraviolet/visible spectroelectrochemistry (UV/vis-SEC) indicates that the coordination of the 2MI modulates interfacial behavior at both the SC/TMOOH and TMOOH/electrolyte interfaces. Specifically, it not only significantly boosts the kinetics of hole transfer, but alleviates the strong adsorption on Fe sites. Moreover, the 2MI molecule can be utilized to create alternative SC/TMOOH systems, for instance, BiVO 4 /NiOOH-2MI and BiVO 4 /CoOOH-2MI, to improve the PEC performance. This study presents an innovative ligand modulation strategy for highly efficient PEC water splitting.

Room temperature phosphorescence (RTP) materials have extensive applications in various fields owing to persistent luminescence and excellent signal-to-noise ratio performance. Nevertheless, the realization of long-lived RTP materials remains challenging due to the spin-prohibited character of the triplet exciton transition. In this study, the bright yellow phosphorescence carbon dot-based composites imbedded in a B2O3 matrix (CDs@B2O3) have been synthesized, and the lifetimes of up to 1.107 s were achieved (naked-eye-detectable persistence lasting over 11 s). XRD, TEM, FT-IR, and XPS analyses were undertaken, and structural analyses reveal that covalent bonds and the confinement effect of the rigid boric oxide matrix effectively constrain the rotation and vibration of CDs' light-emitting groups and suppress nonradiative recombination of triplet excitons. In addition, applications of CDs in fingerprint detection, anticounterfeiting, and information encryption are explored. The research offers fresh perspectives into the development of ultralong afterglow materials for diverse applications.

Chemical oxidation is pivotal in remediating organic pollutants in aquatic systems; however, it frequently yields transformation products (TPs) with potential toxicological profiles surpassing those of the parent pollutants. Comprehensive identification of these TPs is imperative for environmental risk assessment and optimization of oxidation methodologies. Traditional experimental approaches for TP elucidation are often hindered by substantial financial and technical constraints, limiting their applicability in high-throughput scenarios. Here, we introduce TP-Transformer, an advanced deep learning framework designed to predict both the structures of TPs and their corresponding formation pathways. Trained on Chem_Oxi_2K, a meticulously curated data set comprising 2780 pollutant degradation reactions, TP-Transformer achieved a notable accuracy of 86.28% in TP prediction. The model adeptly reconstructs complete degradation pathways, addressing the intricate challenge of pathway elucidation. Attention analyses indicate that the TP-Transformer discerns reactive moieties within substrates and correlates them with specific reaction conditions, emulating expert-level chemical reasoning. Experimental validations corroborate the model’s robustness, with accurate TP predictions ranging from 80.20 to 92.86% for five pollutants absent from the training data set. These findings underscore TP-Transformer’s potential to transform environmental chemistry by offering a scalable, precise, and efficient alternative to traditional experimental methodologies, thereby enhancing water treatment strategies and safeguarding ecological and human health.

In the pursuit of advancing wearable electronics, flexible multifunctional devices that integrate both energy storage and sensing functions offer an effective route to achieve smaller, lighter, and more versatile systems. This study introduces an effective strategy for the in situ laser-induced synthesis of boron–nitrogen codoped hollow carbon nanosphere cages (BNHCNCs). In this approach, boric acid nanoparticles (H3BO3 NPs) are strategically utilized as both the template and the boron doping source, while the polyimide (PI) precursor contributes to the carbon matrix and the nitrogen doping source, and the straightforward hot-water treatment effectively dissolves the H3BO3 template. The resulting BNHCNC patterned electrodes precisely fabricated via laser scribing are subsequently integrated into all-in-one quasi-solid microsupercapacitors exhibited piezoresistive capability (MSCs-PC). that exhibit high specific capacitance, excellent mechanical flexibility, and impressive sensing capabilities, particularly for human motion monitoring and communication technologies. This study not only introduces a general method for synthesizing high-performance carbon nanomaterials but also provides a potential solution for advancing flexible energy storage and wearable electronics, aligned with trends in miniaturization, integration, and multifunctionality.

Carbon-based metal-free materials have garnered significant attention as catalysts for the oxygen reduction reaction (ORR). Among these materials, boron carbon nitride (BCN) has emerged as a promising functional material owing to its exceptional electrochemical stability, superior corrosion resistance, and high specific surface area. However, BCN’s catalytic activity remains suboptimal, possibly due to its weak binding with *OOH. In this study, phosphorus-doped BCN (P-BCN) was synthesized using a one-step calcination approach and employed as an efficient ORR catalyst. P-BCN exhibits a half-wave potential (E 1/2 ) of 0.823 V, which is significantly higher than BCN’s 0.764 V, indicating enhanced ORR activity. Furthermore, after 5000 cycles of accelerated durability testing, P-BCN’s E 1/2 decreases by only 3 mV, demonstrating its robust ORR stability. Both experimental data and density functional theory (DFT) calculations confirm that P-BCN’s remarkable electrochemical performance results from its enhanced *OOH binding, increased carrier concentration, and accelerated charge transfer rate. Additionally, in a zinc-air battery (ZAB), P-BCN delivers an open-circuit voltage of 1.42 V, a peak power density of 155 mW/cm 2 , and a specific capacity of 605 mAh/g, demonstrating practical potential. The novel strategy proposed in this study offers a valuable reference for the broader application of carbon-based metal-free ORR catalysts.

Formaldehyde (FA), a known carcinogen, is occasionally used illegally as a preservative in seafood, while traditional detection methods for FA residues often fail to meet the practical needs for nondestructive detection. In this study, a approach was developed by combining a portable Raman spectrometer with the InceptionTime deep learning model without sample pretreatment. Model were trained by FA-negative and FA-positive Raman spectral data from the shrimp surface and achieved accuracies of 84.40 % and 85.17 % at detection thresholds of 5 mg/kg (the primary safety detection threshold) and 100 mg/kg (the abuse-level contamination threshold), respectively. Metabolomic analysis and weight visualization indicated that the model particularly focused on Raman peaks associated with specific amino acids and astaxanthin-binding proteins. Two amino acid metabolites, timonacic and spinacine, were also identified as direct indicators of FA addition. Our model offers a field-deployable and practical approach for real-time and on-site FA detection scenario.

Conductive hydrogels show great potential for flexible sensors, yet their applications are limited by low strength, poor freeze resistance, and easy dehydration. To address these issues, this paper developed a multifunctional PVA (polyvinyl alcohol)/CMC (carboxymethyl cellulose sodium)/PANI (polyaniline)/PA (phytic acid)/BA (boric acid)/Fe 3+ hydrogel (denoted as PMNF) with a double-network structure formed via the Hofmeister effect and in situ polymerization. The hydrogel exhibits excellent mechanical properties (tensile strength: 236 kPa; elongation: 541%), high conductivity (2 S/m), and improved antifreezing behavior. At −12°C, it retains a conductivity of 0.86 S/m and over 300% elongation. It also demonstrates strong water retention after 15 days and stability in acidic/alkaline salt environments. Based on these properties, PMNF-based sensors reliably detect both subtle and large human motions under various conditions. This work offers a practical strategy for developing robust wearable electronics suited for real-world use.

Aluminum borate whiskers (ABOws) have been widely utilized as a secondary phase for fabricating ceramic composites. The morphology and thermal stability of ABOws play a critical role in achieving their optimal performance. In this study, two precursor powders were synthesized via chemical precipitation and mechanical mixing, followed by the induction of a solid–liquid reaction at elevated temperatures to form ABOws. For ABOws prepared from chemically precipitated powder, a metastable intermediate Al 2.1 B 0.9 O 4.5 phase was first formed at 850°C, which subsequently transformed to Al 4 B 2 O 9 at 1000°C and further evolved into needle-like Al 18 B 4 O 33 with high aspect ratio at 1150°C. In contrast, for ABOws prepared via mechanically mixed powder, the formation of Al 4 B 2 O 9 began at 850°C, and it fully converted to rod-like Al 18 B 4 O 33 at 1150°C. The morphology differences of those two types of ABOws were ascribed to their different nucleation routines. Homogenous and heterogeneous nucleation occurred in the chemically precipitated amorphous and mechanically mixed powders, respectively, leading to the formation of ABOws with different morphologies. The two types of ABOws demonstrated phase composition stability up to 1400°C. However, pronounced morphological changes were observed at 1200°C. These findings offer valuable insights into the microstructure formation process and thermal stability of ABOws with tunable morphologies.

Equimolar Ca2+ and Zr4+ doping was implemented to establish novel garnet-type Gd3‒xCaxAl2.95Ga2‒xZrxO12:0.05Cr3+ (x=0‒2.0) far-red (FR) phosphors. The quantum efficiency and temperature-dependent luminescence analysis successfully produced the optimal x=0.5 phosphor, which exhibited highly efficient (IQE=92.8%, EQE=31.6%) broadband FR-emission peaking at ~714 nm (full-width at half-maximum ~81 nm) and excellent thermal stability (95.5%@423 K) under 450 nm light excitation. Its performance is far superior to that of most reported Cr3+ activated FR-emitting garnet phosphors, and the emission spectrum can well superpose with the absorption band of the far-red phytochrome, making this phosphor have huge potential application in the construction of high-quality FR pc-LED used for plant lighting.
