摘要:
In this study, we developed an intramolecular charge transfer (ICT)-based fluorescent probe (TPA-S-P), which features a donor-π-acceptor push-pull architecture, in which the donor triphenylamine (TPA) moiety was conjugated to the 1-methyltetrahydropyridine (P) acceptor moiety through a thiophene (S) bridge. In the presence of Monoamine Oxidase A (MAO-A), the P acceptor moiety was oxidized to a positively charged methylpyridinium moiety (Ps), which was capable of binding to the negatively charged mitochondrial membrane, resulting in significantly enhanced fluorescent emission signals. Compared with other potential interfering substances, TPA-S-P showed excellent selectivity for MAO-A. We verified the excellent imaging performance of TPA-S-P through the in vitro imaging experiment of SH-SY5Y cell model. TPA-S-P is expected to become a powerful tool to monitor MAO-A activity for the future study of MAO-A related diseases.

摘要:
Sewage sludge is abundant in Si/Al/P-rich inorganic components. Within sludge-derived biochar, these components often serve as inert fillers, reducing porosity, suppressing surface activity, and impairing carbon sequestration. Due to their thermochemical stability, mitigating these adverse effects necessitates extremely harsh processes with high energy consumption, potentially generating hazardous waste. Herein, we developed an integrated pathway combining alkali-mediated pyrolysis with sub-boiling temperature hydrothermal crystallization, converting organics into hierarchically porous carbon while transforming inorganics into sodalite-type (SOD) zeolites to form carbon-zeolite (CZ) composites, with concurrent P recovery as crystalline vivianite. The composite synthesized under optimal conditions exhibits exceptional performance characterized by a high specific surface area (905 m 2 ·g –1 ), hierarchical meso‑microporous structure, and intimate interfacial bonding through SOD embedded within the carbon matrix. These properties enabled superior broad-spectrum adsorption capacities for diverse aqueous and gaseous contaminants, achieving 450 mg·g –1 for Pb(II) and 333 mg·g –1 for Cd(II), while demonstrating effective treatment of complex landfill leachate and mixed electroplating effluents. In-situ mass spectrometry and micro-Raman imaging demonstrate that alkali-mediated pyrolysis lowers activation barriers, enabling selective bond cleavage and carbon fixation via carbanion activation, proton transfer, and β-elimination. Crystallization induces carbon-zeolite interfacial microstress and metastable interfacial C–O–Si covalent bonding, generating O-vacancies and C-defects that enhance active sites. Elemental flow analysis confirmed that sludge-to-CZ conversion achieves valorization efficiencies of 74–91 % for critical elements (C, Si, Al), while enabling 67 % phosphorus recovery as vivianite. Technoeconomic analysis demonstrated the process viability with a 9 % gross margin and 25 % internal rate of return, establishing a sustainable paradigm for near-full-component valorization of sludge.

摘要:
Oxygen has garnered significant attention for its ability to regulate phase transformations in alloys, thereby markedly enhancing their mechanical properties. This study focuses on the structural evolution and mechanical property modulation of FeCrNi alloys. Through oxide doping, single-layer FeCrNi (MEA), Ti 3 Fe 33 Cr 32 Ni 32 (MEA-T) and Ti 3 Fe 31 Cr 30 Ni 30 O 6 (MEA-O) alloys were successfully fabricated by laser directed energy deposition. A combination of experimental methods and molecular dynamics simulations was employed to evaluate alloy performance and analyze deformation mechanisms. The results demonstrate partial melting of TiO 2 in MEA-O, with in-situ synthesized oxide heterostructures significantly increasing geometrically necessary dislocation density, confirming their critical role in promoting dislocation nucleation and strengthening the coating. Furthermore, semi-coherent structures formed between distinct oxides coordinate cross-interface dislocation slip, reducing stress concentration and brittle fracture risk, thereby enhancing load transfer efficiency. Compared to oxygen-free alloys, MEA-O synergistically improves elastic modulus due to nanoscale precipitates and high-density semi-coherent interfaces at phase boundaries that restrict dislocation motion. Additionally, MEA-O coatings exhibit significantly enhanced wear resistance and friction reduction performance under both ambient and elevated temperatures. Conversely, Ti-doped MEA-T alloy shows performance degradation during high-temperature friction tests. Molecular dynamics simulations reveal titanium doping increases the γ usf value of MEA-T, facilitating dislocation slip during deformation. However, precipitation strengthening causes non-uniform distribution of strengthening phases and grain refinement. These strengthening phases and grain boundaries collectively hinder dislocation propagation, increasing stacking fault roughness and stress concentration, consequently degrading the high-temperature wear resistance of the coating.

摘要:
Protein-polysaccharide complexes are important for food structure and emulsion stability, but controlling their functionality through pH-dependent interactions is still challenging. This study aims to investigate the effects of varying pH levels and mass ratios on the formation of quinoa protein isolate (QPI)-κ-carrageenan (κC) soluble complexes. Multispectral analysis, molecular docking, and molecular simulation were employed to examine the interactions, structure-physicochemical properties, and emulsifying characteristics of QPI and κC molecules. The results indicate that QPI-κC complexes with different mass ratios can form soluble complexes at pH 6.0. The fluorescence quenching and molecular docking results indicate that the dynamic fluorescence quenching observed between QPI and κC is primarily due to hydrophobic interactions, hydrogen bonding, and electrostatic forces. The incorporation of κC induces a change in the secondary structure of QPI, resulting in alterations to its crystal morphology and microstructure, thereby facilitating the formation of a stable complex. This is corroborated by the results from X-ray diffraction, scanning electron microscopy, and molecular simulations. Furthermore, the addition of κC enhances the stability of the QPI emulsion during a storage period of 7 d. The findings of this study contribute to the understanding of QPI-κC complexes as stabilizers for Pickering emulsions and their potential applications in food delivery systems.

摘要:
Epoxy resin, known for its excellent mechanical properties, chemical resistance, and dimensional stability, has been widely employed in advanced electronic packaging, high-performance coatings, and aerospace engineering. However, its inherent flammability has limited its applications. To address this issue, a ZnAl-NO 3 -LDH was synthesized via co-precipitation and subsequently modified by ion-exchange intercalation with [SiW 12 O 40 ] 4− to form ZnAl-SiW 12 O 40 -LDH (SiW-LDH). The obtained SiW-LDH was then combined with AMP intumescent flame retardants composed of APP, MEL, and PER to enhance the fire resistance properties of the epoxy–polyamide resin (EP). The resulting 2 %SiW-LDH/AMP/EP coatings containing 24.5 wt% AMP and 2 wt% SiW-LDH exhibited excellent flame-retardant properties, achieving an LOI value of 35.3 % and a UL-94 V-0 rating. Additionally, the total heat release (THR) and total smoke production (TSP) recorded during cone calorimeter tests decreased by 69.7 % and 70.9 %, respectively. Moreover, further analysis of the residual char of SiW-LDH/AMP/EP demonstrated that the catalytic carbonization co-effect of AMP and SiW-LDH promoted the formation of a dense and continuous char layer with aromatic structures containing Al O, W O, Si O, W C, Zn 2+ , P–O–C, and P N moieties. Notably, these structures enhanced the flame retardancy, smoke suppression, charring, and thermal insulation properties of the EP. These properties also originated from the dilution of non-combustible gases and the heat-absorbing action upon the thermal decomposition of SiW-LDH/AMP during combustion. Overall, these results demonstrate that the incorporation of SiW-LDH and AMP into epoxy matrices effectively enhances the flame retardancy and thermal insulation properties of polymer systems.

摘要:
P2-Na 0.67 Ni 0.33 Mn 0.67 O 2 (NNM) is a promising cathode material for sodium-ion batteries, offering a high-voltage plateau (3.7 V) and large theoretical capacity (170 mAh/g). However, its practical application is hindered by structural degradation from interlayer gliding and Mn 3+ -driven Jahn-Teller distortion. To address these, we engineer a dual pinning strategy through K/Zr co-doping, creating a robust cathode (NKNMZ) with exceptional stability. XPS confirms Zr 4+ doping reduces Mn 3+ content, mitigating Jahn-Teller distortion. Electrochemical tests reveal NKNMZ delivers outstanding cycling stability (84.25 % retention after 1,000 cycles at 3000 mA/g) and high-rate capability (72.14 mAh/g at 4500 mA/g). In situ XRD demonstrates suppressed interlayer gliding, reduced lattice strain, and attenuated phase transitions during cycling. DFT calculations further prove K/Zr co-doping strengthens TM–O (TM denotes transition metal) bonds, enhances electronic conductivity, and inhibits TM-layer gliding by promoting electron delocalization. This work establishes a materials design paradigm for stabilizing high-energy layered oxide cathodes via synergistic ion doping.

摘要:
White-light emission with a single activator in a single host is an attractive function of phosphors. In this work, we investigated the photoluminescence properties of Ba 5 (PO 4 ) 3-x (BO 3 ) x Cl, which is a compound derived from apatite type Ba 5 (PO 4 ) 3 Cl by means of diadochic substitution, with Eu 2+ -activation using photoluminescence measurements. Phosphors show a tunable emission from deep blue to white and then orange under near ultraviolet light excitation. In the compound Ba 5 (PO 4 ) 3 Cl, Ba 2+ ions occupy two crystallographically distinct sites; only one site is preferential site for Eu 2+ substitution. Through introducing (BO 3 ) 3− group into the host lattice, additional emission peak is observed. Decay analysis indicates that the second emission is generated by Eu 2+ at another crystallographic site caused by the introducing of (BO 3 ) 3− group. A phosphor-converted light-emitting diode has been successfully fabricated with the incorporation of an as-prepared Ba 4.96 (PO 4 ) 2.6 (BO 3 ) 0.4 Cl:0.04Eu 2+ phosphor and a 365 nm near-ultraviolet chip, which exhibits Commission International de I'Eclairage chromaticity coordinates of (0.3151, 0.3695) and a correlated color temperature of 6173 K. These findings provided a new way for preparing white light phosphors by doping a single activator in a single component.

摘要:
Cherry tomatoes ( Solanum lycopersicum var. cerasiforme ), an economically important crop, are highly susceptible to gray mold caused by Botrytis cinerea during postharvest storage, resulting in deterioration of fruit quality. As a polyunsaturated fatty acid, arachidonic acid (ARA) has been shown to act as an elicitor to induce plant defense responses against pathogens. In the present work, we explored the inducing effects and mechanisms of ARA on gray mold resistance through physiological and transcriptomic analyses. Exogenous ARA increased the activities of defense-related enzymes, such as polyphenol oxidase, peroxidase, catalase, phenylalanine ammonia-lyase, and ascorbate peroxidase, as well as significantly suppressed malondialdehyde accumulation in tomato. Transcriptomic analyses revealed that ARA treatment highlighted coordinated changes in the key pathways, including phenylpropanoid biosynthesis, plant-pathogen interaction, and MAPK signaling pathway, resulting in enhanced resistance against B. cinerea in tomato. The up-regulation of calcium signaling-related genes ( CDPK and CNGCs ) induced early reactive oxygen species burst and hypersensitive response. MEKK1-MKK1/2-MPK4 and MEKK1-MKK4/5-MPK3/6 cascade in the MAPK signaling pathway regulated transcription factors (WRKY25/33, WRKY22/29, Pti5, and Pti6), which in turn induced defense-related genes ( PR1 and ChiB ). Concurrently, the upregulation of key genes ( 4CL , PAL , POD , CCoAOMT , and CYP98A3 ) in the phenylpropanoid metabolic pathway promoted lignin deposition and the accumulation of antimicrobial compounds, establishing a dual-layered physical-chemical defense barrier. This study provides new insights into the resistance of cherry tomato against B. cinerea induced by ARA.

摘要:
Breaking the trade-off between activity and selectivity has always been a long-standing challenge in the field of catalysis. In this study, we introduce an innovative universal pseudo-fluctuation strategy utilizing surface-uncoordinated In(OH) 3-x -ZnIn 2 S 4 heterojunctions (ZIO) to achieve local free radical confinement. Notably, the low-coordination and contraction of In−O bonds generate disordered and loosely hydrogen-bonded chains, which enhances the adsorption and activation of toluene. Meanwhile, the dynamic transformation of In−O bonds regulates the d‐band center while restructuring a dense hydrogen bonding network. This process locally confines highly reactive oxygen species and facilitates the desorption of benzaldehyde, effectively inhibiting the over-oxidation of the product. Ultimately, after 48 h of irradiation, the photocatalytic toluene oxidation rate of ZIO-2 reached 100.59 mmol g −1 without generating excessive oxidation by-products. Our work delineates a clear surface reaction pathway and introduces a novel design paradigm for atomic-scale photocatalysis in multi-state interfaces, paving the way for advanced catalysts that harness interfacial microenvironments to achieve enhanced performance.

摘要:
Colletotrichum fructicola is the major pathogen of anthracnose on tea-oil trees. It can be controlled by carbendazim (methyl benzimidazol-2-ylcarbamate, MBC), which targets to α−/β-tubulin heterodimers. C. fructicola contains Cfα1tub, Cfα2tub, Cfβ1tub and Cfβ2tub tubulins. The interaction patterns and functional divergence of these tubulins in regulating MBC sensitivity are not understood. In this study, we found that Cfβ2tub-Cfα1tub and Cfβ2tub-Cfα2tub heterodimers are superior in numbers. Cfβ1tub-Cfα1tub and Cfβ1tub-Cfα2tub can only be detected in Cfβ1tub overexpression mutant. Deletion of Cfα1tub or Cfα2tub increases Cfβ1tub expression without affecting MBC sensitivity. In the absent of MBC, Cfα2tub and Cfβ2tub protein levels are higher than Cfα1tub and Cfβ1tub. In the present of MBC, Cfα1tub, Cfα2tub and Cfβ2tub can be degraded via 26S proteasome. In contrast, Cfβ1tub is induced in wild-type strain and much higher in Cfβ2tub deletion mutant ( Cf Δ β2tub ). Moreover, the less MBC sensitivity of Cfβ1tub overexpression mutant and equal binding affinity between Cfβ1tub-, Cfβ2tub-containing heterodimers and MBC indicate that the resistance of Cf Δ β2tub is resulted from constitutive high expression of Cfβ1tub . Despite Cfα2tub protein level is lower than Cf Δ β2tub , Cfα2tub degradation could be relieved in response to MBC . Taken together, these findings are clearly differed from another important plant pathogenic fungi Fusarium graminearum and provide a better understanding about interaction and expression patterns of C. fructicola α- and β-tubulin isotypes in response to MBC, which can be useful for developing new tubulin-targeting agents.

摘要:
CO oxidation represents a critical environmental strategy for purifying exhaust streams from automotive and industrial sources. However, developing high-performance, cost-effective non-precious metal catalysts with low-temperature activity remains a major challenge. In this work, we synthesize CuO/Cu 1.5 Mn 1.5 O 4 (CuMn-MMO-T) heterojunction catalysts via temperature-controlled calcination of CuMn-LDH precursors. The optimized CuMn-MMO-400 catalyst remarkably achieves complete CO oxidation at 170 °C under a high gas hourly space velocity of 41,200 mL g −1 h −1 . It maintains 100 % CO removal across a broad temperature window (170 −400 °C) and demonstrates exceptional stability over 60 h of continuous operation at 400 °C. In situ analysis reveals the synergistic interface between CuO and Cu 1.5 Mn 1.5 O 4 promotes reactant adsorption and lattice oxygen migration, enabling efficient oxidation of CO to CO 2 through a Mars-van Krevelen (MvK) mechanism. Density functional theory (DFT) calculations confirm CuO adsorbs CO, while Cu 1.5 Mn 1.5 O 4 provides lattice oxygen to achieve the oxidation of CO. This work provides fundamental insights into lattice oxygen activation mechanisms in heterostructured oxides and paves the way for rational design of transition metal catalysts for energy-efficient CO emission control.

摘要:
The focus was on the wear mechanism and high-temperature oxidation behavior of metal matrix composite (MMC) coatings. With increasing TiC, the microhardness of the MMC coatings increased to 1353.08 HV 0.5 . However, excessive TiC will initiate fatigue cracks. 20 wt% TiC coating reduced wear rate by 99.48 % compared to the substrate, because of fine-grain reinforcement and hard phases. At 600 ℃, a high-density TiO 2 oxide film and a Cr 2 O 3 friction film synergistically reconstructed on the coating surface, resulting in the lowest wear rate at high temperature (7.65 × 10 −6 mm 3 / N⋅m). After high-temperature oxidation, the MMC surface formed a denser and more uniform oxide film, while the oxidation resistance of the coating showed a linear relationship enhancement with adding TiC.

摘要:
As a key raw material in the paper industry, Eucalyptus has been widely cultivated in commercial plantations; however, the ecological impacts of these plantations require systematic evaluation. Soil multifunctionality is vital in maintaining ecosystem services, enhancing sustainability, and regulating nutrient balance. Long-term Eucalyptus cultivation can disrupt soil nutrient balance; however, its effects on soil multifunctionality remain unclear. This study compared single-generation (SG) and multiple-generation (MG) Eucalyptus plantations with an evergreen broadleaf forest (CK) to assess how prolonged Eucalyptus cultivation alters soil nutrient stoichiometry, subsequently affects keystone taxa diversity, and ultimately reduces soil multifunctionality. The MG plantations exhibited pronounced nutrient stoichiometric imbalances, with soil C/N, C/P, C/K, N/P, N/K, and P/K ratios reduced by 60.17–83.27 % relative to CK, accompanied by a 19.9 % decrease in the Chao1 richness and a 6.1 % decrease in the Shannon index of keystone taxa. Long-term Eucalyptus planation reduced soil multifunctionality from 0.187 to − 0.355, largely via nutrient stoichiometry driven erosion of keystone-taxa diversity. Keystone taxa, especially Proteobacteria , Actinobacteriota , and Chloroflexi , played critical roles in regulating nutrient cycling. Partial least squares path modeling (PLS-PM) and threshold indicator taxa analysis (TITAN) revealed that nutrient stoichiometry and enzymatic activity influenced soil multifunctionality directly and indirectly by modulating keystone taxa diversity and community structure. These findings underscore the essential role of keystone taxa diversity in maintaining soil functions and offer new insights into microbial–nutrient interactions regulating ecosystem services. This study provides valuable guidance for Eucalyptus plantation management, emphasizing the need to consider microbial and nutrient interactions in balancing industrial productivity with ecological sustainability.

摘要:
Biological staining is essential for imaging, functional investigation, and disease diagnostics. In this research, innovative green-emissive carbon dots (G-CDs) were hydrothermally prepared from 1,2,4-triaminobenzene and ascorbic acid (AA) and further explored for versatile imaging of mammalian cells, plant cells, and microorganisms. The G-CDs, exhibiting fluorescence enhancement, outperform conventional dyes in terms of staining efficiency and specificity across various biological systems. For mammalian cells (SH-SY5Y, Hep3B, and HEK293), the G-CDs can stain both the nuclei and nucleoli in 10 min via a micropinocytic endocytosis approach, with the latter brighter. Fluorescence enhancement was greater for RNA than for DNA. Interestingly, for plant cells, only cell walls were stained, because positive charges on G-CDs enable strong adsorption onto the negatively charged cell walls, thereby hindering their further entry. G-CDs can stain cell walls and nuclei for fungi (including Aspergillus flavus and Aspergillus niger ), and cell walls and nucleoids for bacteria ( Bacillus subtilis and Escherichia coli ). The targeted staining arises from both the binding of G-CDs to DNA, RNA, pectin, peptidoglycan, and cellulose, and fluorescence enhancement due to surface passivation inhibiting rotation and vibration of functional groups. Electrostatic interactions, coordination, hydrogen bonding, and amidation collectively account for the interactions between G-CDs and these biomolecules . Finally, their practical applications in leucorrhea examinations demonstrated their capability to differentiate between bacterial and fungal vaginosis, highlighting their potential in clinical diagnostics.

摘要:
Manganese-based Prussian blue analogues (Mn-PBAs) are considered top contenders for cathode materials in sodium-ion batteries (SIBs). Yet, their electrochemical performance is significantly hindered by the presence of numerous [Fe(CN) 6 ] 4− vacancies and Jahn-Teller distortion of Mn. To address this, a technique involving chaotic microflow field utilization and Ni-doping was adopted to prepare a series of MnNi-PBAs with different Mn/Ni ratios. Computational fluid dynamics (CFD) analysis confirms that the oscillating feedback microreactor (OFM) enables effective chaotic mixing and a homogeneous concentration distribution. Consequently, Mn 4 Ni 4 -PBA synthesized using OFM (F-Mn 4 Ni 4 -PBA) displays reduced [Fe(CN) 6 ] 4− vacancies and a more even Mn–Ni elemental distribution. Density functional theory (DFT) computations indicate that Ni-doping enhances conductivity, lowers the energy barrier for sodium ion diffusion, and mitigates Jahn-Teller distortion. Uniform Mn–Ni elemental distribution in skeleton lowers formation energy, indicating stability. Remarkably, F-Mn 4 Ni 4 -PBA demonstrates stable capacity retention (100 %) under low temperature conditions (−20 ℃, 150 mA/g, 2000 cycles).

摘要:
In this work, we present a pest-natural enemy model with natural enemy periodic migration described by time delay. The globally attractive conditions for pest-elimination periodic solution ( 0 , 0 , P ( t ) ˜ ) of model ( 2 . 1 ) are acquired by methods of mathematical analysis. Permanent conditions of model ( 2 . 1 ) are also provided. Computer-assisted techniques are used to simulate the dynamical behaviors of model ( 2 . 1 ) . Furthermore, Systematic sensitivity analysis of parameters are inserted to describe the dynamic interactions between pests and their natural enemies. Our results are more closer to pest management with periodic migration and enrich theories of integrated pest management.

摘要:
Efficient, low-energy CO 2 capture technologies are crucial for reducing carbon emissions. However, conventional porous carbon materials typically suffer from low adsorption capacity, poor selectivity, and high energy consumption. In this study, polypyrrole carbon spheres were synthesized using pyrrole as both carbon and nitrogen sources, and nitrogen-doped ultramicroporous carbon materials (NPCS) were prepared through mechanical compaction assisted activation. Compared to NPCS700-0T (conventional activation), NPCS700-3T (mechanical compaction assisted activation) exhibited significant improvements in pore structure, with a 73 % increase in specific surface area and a 58 % increase in ultramicroporous volume, resulting in a 53 % higher CO 2 adsorption capacity at 25 °C and 1 bar for NPCS700-3T than NPCS700-0T. Pearson correlation analysis showed that CO 2 adsorption at 1 bar was strongly correlated with ultramicroporous volume, while nitrogen and oxygen content played an important role in CO 2 adsorption at 0.15 bar. Furthermore, NPCS600-3T demonstrated a CO 2 /N 2 selectivity of 53 at 1 bar, highlighting the synergistic effect between ultramicroporous volume and surface chemical composition. Solar-driven CO 2 desorption experiments revealed that NPCS700-3T and NPCS800-3T achieved desorption rates of 70 % and 79 %, respectively, under one-sun illumination, with corresponding desorption capacities of 2.39 mmol g −1 and 2.16 mmol g −1 . These results provide promising solutions to the challenges of low CO 2 adsorption capacity, poor selectivity, and high energy consumption.

摘要:
Slowpoke (Slo) channels are vital components of the nervous system, making them promising targets for developing neuromodulatory pesticides. However, there is limited research on the physiological roles and inhibitors of Slo channels in agricultural pests like the brown planthopper ( Nilaparvata lugens ). This study investigates the composition and essential functions of Slo channels in N. lugens through gene sequence analysis, patch-clamp electrophysiology, and inhibitor bioassays, offering valuable information for pest control approaches targeting these channels. The full coding sequence (3513 base pairs) of the N. lugens Slo gene was cloned, and five alternative splicing regions labeled A, C, E, G, and I were identified. Whole-cell patch-clamp experiments showed that the NlSlo channel exhibits typical features of calcium-activated large-conductance potassium channels, with a half-activation voltage (V 1/2 ) of 18.04 ± 0.94 mV. Removing the E region notably enhanced the channel's response to depolarization, while deleting the I region significantly reduced channel current. Among the tested inhibitors, iberiotoxin produced the strongest inhibition of the NlSlo channel at 66.21 % when applied at 10 μM, whereas plant-derived compounds inhibited the channel by 24.2 % to 48.95 % at the same concentration. In comparison, five pesticides—transfluthrin, flonicamid, tebufenozide, acynonapyr, and cypermethrin—showed inhibition rates ranging from 30.11 % to 42.74 % at 100 μM. Notably, injections of the specific inhibitor iberiotoxin significantly decreased both survival and movement abilities in N. lugens . This research highlights the critical role of Slo channel inhibition in affecting the survival and locomotion of N. lugens , providing new perspectives for developing pest management strategies targeting this species.

摘要:
Detection of surface defects from images is crucial to ensure high quality products in manufacturing applications, where surface detection of small defects plays a vital role and has received much attention in the manufacturing industry. However, existing detection solutions perform unevenly in different small defect scenarios. Therefore, this paper proposes an efficient enhancement strategy (RAI) to enhance the model’s ability to detect small surface defects. It consists of two major parts: (i) the feature information enhancement part (ASFR), which consists of a frequency balance (FB) module, an adaptive dilation convolution kernel (ADCK) module, and a spatial feature reorganization (SFR) module, to progressively enhance the semantic information of small defects; and (ii) the subsequent-stage correction interpretation part, which consists of a cross-stage query injection (CQI) mechanism to correct the training focus imbalances and the cascading errors, and fine-grained interpretation of minor defect features. On the engineering side, we applied the strategy to Deformable-Detection Transformer (DETR), Dynamic Anchor Boxes-DETR, and Adamixer, based on three datasets: a self-constructed bamboo slice defect dataset, a defect dataset from Northeastern University, and huggingface surface defects. The experiments were conducted, and mAP50 was improved by 1.7% to 12.5% on the bamboo slice defect test set, 2.4% to 7.8% on the NEU-DET test set, and 2.8% to 4.0% on the huggingface surface defect test set.

摘要:
The present review comprehensively surveys the current applications of organostibines, covering the chemical, biological, and materials sectors. In the field of chemistry, the preparation processes of organostibines are described, including metal reagent exchange and catalytic methods for the synthesis of different Sb-Z (Z = C( sp , sp 2 , sp 3 ), O, S, N) bonds. Additionally, the applications of related organostibines as metal reagents, organometallic ligands, and catalysts are also described, and the corresponding schematic mechanisms are summarized to facilitate further research on organostibine derivatives from this class of compounds. In the biological field, organostibines serve as vital drug molecules in treating leishmaniasis, cancer, and bacterial infections. Furthermore, they are effective in the repair of blood vessels and the transportation of fluoride ions. Materials science is employed in the detection of fluoride ions, the modification of ceramic surfaces, and the alteration of polymer viscosity. By providing a comprehensive overview of organostibines, we can offer researchers direction and a research focus for subsequent developments and applications in antimony chemistry, thereby promoting its vigorous development.
