However, conventional carbon foams are limited by low levels of graphitization and a lack of long-range structural order, restricting their use in high-performance applications. Traditional synthesis methods, such as templating, chemical activation, and hydrothermal processes, although effective in forming porous structures, are complex and inefficient. To overcome these limitations, this study introduces a novel one-step water explosion method that combines Joule heating and steam activation to synthesize highly graphitized porous carbon foam. By rapidly vaporizing intercalated water molecules between graphite layers, the method overcomes van der Waals forces, leading to the exfoliation of the material. The process, conducted under ultra-high temperatures in less than 1 ​s, produces carbon foam with high porosity, large surface area, and excellent electrochemical performance. In lithium-ion battery tests, the carbon foam exhibited a high capacity of 516.2 mAh/g at 0.1 A/g and retained 92.77 ​% of its capacity after 1100 cycles. This efficient and scalable synthesis technique offers a promising pathway for the development of advanced anode materials in energy storage applications, significantly outperforming conventional graphite-based materials.</div></div>","PeriodicalId":20742,"journal":{"name":"Progress in Natural Science: Materials International","volume":"34 6","pages":"Pages 1207-1215"},"PeriodicalIF":4.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360242","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}

The results indicate that the cyclic softening degree of 316LN austenitic stainless steel increases proportionally with the strain amplitude. This increase can be attributed to variations in the arrangement and development process of the dislocation structure. Additionally, it was observed that both back stress and friction stress augment as the total strain amplitude increases. This phenomenon is primarily caused by enhanced interactions between dislocations and precipitated phases, as well as dislocations themselves. The hysteresis loop area exhibits an increase in direct correlation with the total strain amplitude. Moreover, a smaller strain amplitude corresponds to reduced plastic strain energy and increased fatigue life. In engineering applications, the simplicity and universality of a model, along with easily obtainable parameters, are crucial considerations. To evaluate the fatigue life of 316LN austenitic stainless steel, four models were employed: Coffin-Manson fatigue life model, energy life model, three-parameter power model, and three-parameter power life correction model. The predicted data from the three-parameter power life correction model fell within the acceptable error range of 1.2, demonstrating a strong alignment with the experimental values. Consequently, it can be concluded that the three-parameter power life correction model exhibits remarkable accuracy in predicting low cycle fatigue (LCF) behavior, thereby facilitating the safety assessment of component lifespan. The fatigue fracture surface exhibits distinct features of fatigue striations, with a noticeable decrease in the interval between these striations as the total strain amplitude increases.</div></div>","PeriodicalId":20742,"journal":{"name":"Progress in Natural Science: Materials International","volume":"34 6","pages":"Pages 1194-1206"},"PeriodicalIF":4.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143339007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
