For the past decade, metal oxides (MO) have been identified as plentiful supplies with excellent electrochemical properties, low cost, an abundance of hydroxyl groups, and environmentally acceptable alternative to currently available materials. Their intriguing properties such as extremely large surface area, low synthesis cost, and so on, make them ideals for many applications. This review covered MO structure, characteristics, and current preparation methods. MO/metal nanoparticles and MO/carbon nanoparticles are also addressed as electrocatalysts, co-catalysts, or supports, especially in PEMFC and DMFC applications. This review also examined the effects of different MO nanoparticles in polymer and biopolymer membranes on membrane characteristics. Finally, the existing issues and future perspectives of MO nanoparticles are also discussed in this review.

The microstructure after heat-treatments was predominantly martensite, with low fraction of bainite and ferrite. The tensile tests showed a 100 MPa improvement in strength and a doubling of the total elongation with the increase in heating rate. The tempering process considerably enhanced the ductility from 1–4% to up to 14% in the samples treated at fast heating rates..Furthermore, the work hardening capacity of ultra-fast heated steel was superior compared to steel treated under conventional quenching and tempering. The results suggest that the tempering stage after ultra-fast heat-treatments and quenching further improves the properties compared to the standard quenched and tempered condition.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"1 1","pages":"2417 - 2432"},"PeriodicalIF":1.8,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84623294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the prismatic slip has a significant effect on the strain hardening rate, the activation of {10-12} extension twinning (ET) can significantly reduce the strain hardening rate and the compressive yield strength.

The compression results indicated that the open-cell Al–Si alloy foams exhibited smoother stress–strain behaviour and higher compressive strength than that of previous studies, despite a larger number of defects in brittle Al–Si matrix. The successive occurrences of multiple deformation bands owing to the mixed structure and various defects were responsible for the smooth compression stress–strain behaviour.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"7 1","pages":"2433 - 2445"},"PeriodicalIF":1.8,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85611390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that the wear resistance of ADI was sensitive to hardness and service conditions. Under mild wear conditions, the low-hardness ADI sample exhibited high wear resistance because graphite was easy to transfer to the tribosurface and acted as a lubricant to reduce the friction coefficient. However, the high-hardness ADI sample was hard to deform plastically, which restricted the transfer of graphite from the matrix to the tribosurface. Under severe wear conditions, the plastic deformation of the low-hardness ADI sample gave rise to abrasive wear, which resulted in poor wear resistance. With the deterioration of wear conditions, the wear mechanism of ADI was transformed from micro-cutting wear to oxidative wear.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"55 1","pages":"2409 - 2416"},"PeriodicalIF":1.8,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82112320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cyclic damage-coupled cohesive zone model is proposed to describe the fatigue crack initiation and propagation at the interface between the coating and the substrate. Our results indicate that a high interfacial strength leads to a significant stress concentration owing to the increasing interfacial stiffness. Moreover, high interfacial strength delays interfacial crack propagation but promotes the accumulation of deformation energy in the substrate, which accelerates fatigue crack initiation in the substrate.

The triangular, square and rectangular copper/copper silicide nanostructures are deposited on silicon substrates with (111), (100) and (110) orientations respectively, by thermal evaporation of metallic copper at different substrate temperatures. Investigations confirm that the nanostructures consist of a pure copper layer on top of a copper silicide layer. The morphology and growth behaviour studies confirmed for the first time that the formation of well-defined structures and shapes are governed by the Si substrate orientation and the surface reconstruction of the Si planes. The copper silicide nanostructures are used in field emission applications and also serve as a template for the growth of carbon nano-fibre.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"19 1","pages":"2341 - 2352"},"PeriodicalIF":1.8,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74939665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
