In the last century, several research papers focusing on hydrogen damages were published, including investigations concerning the hydrogen impact on the crack growth rate in steels subjected to cyclic loading. However, the past studies focused on material behavior and the role of external factors (e.g., pressure, temperature, stress field, microstructure, inhibitors, etc.), while the consequences of these findings on safety procedures and guidelines remain unspoken. The present work aims at investigating how the manifestation of the hydrogen degradation effect on equipment subjected to fatigue loadings may reflect on conventional safety practices. More accurately, a review of the parameters governing pipeline fatigue life is undertaken to analyze how such variables may lead to undesirable events and ultimately promoting a loss of containment scenario. In this sense, this work appeals for an evolution of the existing inspection methodologies for components that may experience fatigue failures (i.e., piping and pipeline systems), since the time-dependency of the detrimental effects induced by hydrogen should be considered in the operations of accident prevention and risk mitigation. Hence, the development of a preventive inspection and maintenance strategy specifically conceived for hydrogen technologies is essential to avoid the loss prevention of hydrogen systems. This will not only contribute to a quicker and larger scale spread of a hydrogen infrastructure, but it will also foster the energy-transition challenge that our society is facing today.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"126 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140599873","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}

Noteworthy designs utilizing tetrahedral building blocks include the Sierpiński tetrahedron (the most fundamental three-dimensional fractal), a one-dimensional helical structure known as the tetrahelix, and various crystalline and quasicrystalline packings. Historically, the practicality of tetrahedral superstructures has been evident, providing stable, well-defined frameworks for various constructions, including truss bridges, tower cranes, and electricity transmission line pylons. In the field of self-assembled nanocrystal superlattices, tetrahedral nanocrystals, as building blocks, occupy a unique place among all the possible nanoscale particles. Mathematical models, simulation work, and experimental studies using nanocrystals in the laboratory have suggested that self-assembled structures derived from nanoscale tetrahedral building blocks are notably intricate, giving rise to new horizons of high-entropy nanocrystal superlattices. An important implication from previous works is that such tetrahedral nanocrystal superlattices form through highly delicate interparticle interactions, emphasizing the importance of the fine features of these nanocrystals. In this article, we summarize the advances in superlattices assembled from tetrahedral nanocrystals. We first define the tetrahedron and tetrahedron analogues based on Conway’s transformation and graph theory, underscoring their relevance to the crystallization process producing tetrahedral nanocrystals. Then, we showcase previous reports on the synthesis of tetrahedral nanocrystals and the resulting nanocrystal superstructures. Finally, we conclude by offering insights and perspective into the chemical and architectural intricacy that could emerge from tetrahedral nanocrystals.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"22 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311935","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}
