In this study, we introduce a dynamic Schiff base-based aromatic self-healing system to improve durability and mechanical resilience of flexible fabrics. Dynamic imine bonds formed between cinnamaldehyde and 3-aminopropyltriethoxysilane (APTES) were integrated into a polyurethane (PU) matrix, forming a self-healing material with conjugated aromatic Schiff base bonds. The resulting Schiff base-polyurethane (PSB) exhibited synergistic self-healing behaviour, driven by hydrogen bonding (HB) interactions between siloxane unit and PU, alongside UV (365 nm) activated dynamic crosslinking imine bonds. The PSB film demonstrated excellent mechanical properties(tensile strength: 2.73 MPa, elongation:68 %) and retained 65 % healing efficiency within 20 min (tensile strength:2.08 MPa, elongation: 275 %) while maintaining the aroma. When applied as a protective fabrics coating, PSB significantly enhanced mechanical strength of the cotton fabric and leather. The mechanical analysis of cotton fabric coated via dip and spray coating techniques demonstrated uniform coating and higher healing efficiency within 20 min for dip coating compared to spray coating. The dip coated fabrics showed enhanced mechanical property (tensile: 11 N/mm; elongation: 16 %) and after healing retained a tensile strength of 9 N/mm and elongation of 14 %, with an 80 % healing efficiency. Further, the PSB-coated leather healed surface cracks within 20 min, achieving 76 % healing efficiency and excellent mechanical recovery (tear resistance: 39 N/mm). This aroma-Schiff base-based self-healing polyurethane exhibited enhanced mechanical properties, strong adhesion towards fabrics and a sustained fragrance, making it suitable for advanced soft surface applications.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"207 ","pages":"Article 109431"},"PeriodicalIF":6.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we developed MiniMaxAD, a efficient autoencoder designed to efficiently compress and memorize extensive information from normal images. Our model employs a technique that enhances feature diversity, thereby increasing the effective capacity of the network. It also utilizes large kernel convolution to extract highly abstract patterns, which contribute to efficient and compact feature embedding. Moreover, we introduce an Adaptive Contraction Hard Mining Loss (ADCLoss), specifically tailored to FRADs. In our methodology, any dataset can be unified under the framework of feature-rich anomaly detection, in a way that the benefits far outweigh the drawbacks.

Laboratory experiments on pristine CFRP samples indicate improved structural capacity and highlight the adverse impact of premature debonding. This study aims to gather essential field data regarding the performance of CFRP composites on deteriorated 57-year-old concrete through 27 concrete samples subjected to three distinct mode II (in-plane shear) loading conditions. The samples were extracted from the diaphragms of the recently deconstructed Champlain Bridge in Canada. To test the field samples, modified single and double lap shear configurations were developed that eliminated the need for directly gripping the CFRP sheets, and the results were subsequently compared to a more conventional single lap shear test. The influence of existing defects on bond behaviour and the effect of test configuration on interface performance under single-mode loading were evaluated. Three-dimensional digital image correlation (DIC) was employed to capture full-field in-plane and out-of-plane displacement data, thereby addressing the strain measurement challenges in bonded interfaces and confirming the occurrence of mode I deformations (out-of-plane peeling) during debonding. Experimental strain measurements at failure predominately ranged from 2500 to 3400 microstrain, with a maximum of 4739 microstrain, which is approximately 56 % of the debonding strain predicted by ACI PRC-440.2.23. The strain limit set by the Canadian Highway Bridge Design Code (CAN/CSA S6:19) exceeded the maximum experimental strain by 27 %. Results indicated that the double lap shear test provided more consistent peak loads, while the single lap shear configuration exhibited greater variability. The bond stress-slip behaviour along the length of the CFRP sheet was found to vary significantly; an analytical comparison of experimental data with existing cohesive zone models demonstrated a strong correlation with local bond stress-slip results in certain regions that reached high levels of bond stress. In contrast, other regions showed both lower peak stresses and lower stiffness than predicted by most models, which may be attributed to local deterioration or defects at the CFRP-concrete interface.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"487 ","pages":"Article 142002"},"PeriodicalIF":7.4,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To establish this result, we characterize analytically the response of aggregate output to sector-specific government spending shocks in a tractable production-network economy, showing how it maps into various characteristics of the shocked sector. The response is larger when government spending originates in sectors with a relatively small contribution to private final demand, low markup, high labor intensity, and in those located downstream in the supply chain. We confirm these predictions and evaluate their quantitative relevance within a calibrated multi-sector model of the U.S. economy that embeds several dimensions of sectoral heterogeneity. Leveraging this model, we illustrate how differences in the sectoral composition of purchases across U.S. government levels lead to large variation in the spending multiplier. The latter ranges from 0.47 for federal defense spending, which is relatively concentrated in upstream capital-intensive manufacturing, to 0.82 for state and local spending, which is mainly oriented towards downstream labor-intensive services. Finally, we exploit heterogeneity in the sectoral composition of military spending across U.S. states to provide empirical evidence supporting our theoretical predictions.</div></div>","PeriodicalId":48436,"journal":{"name":"Journal of Public Economics","volume":"248 ","pages":"Article 105404"},"PeriodicalIF":4.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
