However, visual tracing is highly desire to promote the process of study on NPs migrant. Here, the distribution and growth effects of polystyrene (PS) NPs on garlic sprouts ( Allium sativum L.) were evaluated utilizing boron-doped carbon nanoparticles (BCNPs). Both BCNPs and the phospholipids in the cell membrane are hydrophobic. The experiment investigated whether phospholipids compete with BCNPs in the BCNPs/PS system. The objective was to evaluate the stability of BCNPs/PS and minimize interference from free BCNPs. The accumulation of NPs in garlic sprouts was observed via confocal laser scanning microscopy through fluorescence signals originated from BCNPs/PS composite, which was verified by biological SEM. The main accumulation appeared at root epidermal cells and vascular system along with 30 days incubation. Notably, the growth-promoting effect for roots lengthen was revealed in BCNPs group owing to inherent properties of carbon nanomaterials and existence of boron elements. Based on the fluorescence imaging results, the “apoplast entry mode” for BCNPs/PS was reasonably inferred. Excellent fluorescence tracing performance demonstrates that the metal-free BCNPs with merits of low cost and excellent fluorescence performance will be a potential tool for NPs tracing and migrant explorations.","PeriodicalId":45577,"journal":{"name":"材料工程","volume":"3 1","pages":"100058-100058"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147879724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was shown that Si3N4f/BNi fibrous monolithic ceramic possessed outstanding fracture toughness with the KIC value of 13.06 MPa·m1/2 while retaining the flexural strength of 603.59 MPa. This indicated that the BN interfaces extended the crack propagation path and improved the fracture toughness of ceramics. Meanwhile, the densification of ceramics was efficiently promoted by the constant application of pressure starting from room temperature during the sintering process, with a density of up to 3.18 g/cm3. An innovative fiber inclusion model was first established to calculate the residual stress, and predict the flexural strength considering residual stress. This work offers new prospects for the synchronous realization of high strength and toughness in Si3N4 ceramics and for predicting the strength of fibrous monolithic ceramics.","PeriodicalId":45577,"journal":{"name":"材料工程","volume":"40 23","pages":"3308-3321"},"PeriodicalIF":0.0,"publicationDate":"2025-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
