The results of experimental studies and numerical simulations showed that the size of the γ' phase and the stress rupture property were positively correlated with the thickness of the blades and that the cooling rate and the residual stress were negatively correlated with it. Additionally, the residual stress decreased from 200 to 50 MPa as the thickness of the blades increased which followed the same trends as the geometrically necessary dislocation (GND) density.

The Bi<sub>3</sub>O<sub>4</sub>Br/MMT composites demonstrated a remarkable degradation efficiency of nearly 90% for 2-MBT within just 3 min of visible-light irradiation, surpassing 99% after 7 min, along with exceptional cycling stability and structural integrity.

These materials are derived from the selective etching of 'A' element atomic layers from MAX phases in acidic solutions containing aqueous fluoride. The unique chemistry and morphology of MXenes enable their use in a variety of applications, including energy storage, electromagnetic interference shielding, antibacterial activity, water nanofiltration, reinforcement, nuclear waste management, and catalysis. This review provides a comprehensive overview of the synthesis of MXenes, their structure, intercalation, delamination, and properties, offering a thorough understanding of the relationship between their nanostructure and electrochemical performance. This understanding is crucial for advancing the study of 2D MXenes in energy harvesting applications. MXene-based energy devices have garnered significant attention in fields such as medicine and industry. However, there are challenges in developing MXene-based sensors, solar cells, photodetectors, batteries, and supercapacitors with high sensitivity, mechanical stability, and long lifetimes. In this work, we present the methods of MXene preparation, computational analyses, and the resulting morphology and electrical properties. The findings from both computational and experimental approaches influence their applications. Specifically, MXene-based sensors exhibit high sensitivity, solar cells demonstrate high efficiency, and batteries offer long lifetimes and excellent mechanical stability. These exceptional properties make MXenes highly suitable for use in advanced wearable devices.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 13","pages":"5649 - 5685"},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When subjected to friction, the HEA coating absorbs and releases stress and activates dislocations during this process. The stacking faults caused by dislocation movement are mainly located in the HEA coating. This mechanism reduces the stress and defect depth in the Ti matrix, and effectively prevents the damage caused by friction to the lattice structure of the Ti matrix. At the same time, a large number of stationary dislocations are generated during the friction process, and tangles are formed, resulting in work hardening and improving the strength and hardness of the coating.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 12","pages":"5442 - 5458"},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
