Recently, neuromorphic computing represented by photonic circuit neural networks and all-optical diffraction neural networks has attracted widespread attention due to their ultra-fast and ultra-efficient computing architectures. In this perspective, we first review some representative works and introduce them through two main lines of planar photonic circuit neural networks and three-dimensional diffraction neural networks to compare their characteristics and performance. We further discuss programmable designs for neuromorphic computing hardware, which bring it closer to general-purpose computing devices. Besides intelligent neural networks in the optical band, we also review the development and application of the diffractive neural networks in the microwave band, showing their programmable capabilities. Finally, we present the future directions and development trends of intelligent neuromorphic computing and its potential applications in wireless communications, information processing, and sensing.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":19016,"journal":{"name":"MRS Communications","volume":"242 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139768466","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}

Braunovic & Alexandrov’s 1994 article, <i>Intermetallic Compounds at Aluminum-to-Copper Electrical Interfaces: Effect of Temperature and Electric Current</i>, has become a seminal contribution on Al-Cu joining for electrical applications. Their detailed measurements of resistance and intermetallic diffusion rates have become a baseline for assessing the operational performance of Al-Cu joints. The paper has had an increasing citation rate since publication and is in multiple electrical contacts textbooks. However, a minor error has been discovered in the presented analysis. In this short communication, the error is identified and a corrected analysis is provided. The corrected analysis shows that Al-Cu intermetallic growth is ten times slower than previously presented. The corrected analysis has a consequential impact on the utility of Al-Cu joints in electrical applications. Therefore, highlighting the error provides valuable insight for utilising and developing Al-Cu welding in electrical applications.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":19016,"journal":{"name":"MRS Communications","volume":"153 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139585688","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}

In this work, isothermal calorimetry and deconvolution operation were used to obtain the hydration degree of MKPC suspension system at various stages under different M/P conditions. A complete mathematical equation for hydration degree was obtained by integrating the parameters of the log–normal function at different stages of hydration. The results show that the hydration process of MKPC were successfully and accurately determined using the lognormal function and deconvolution method. Hydration kinetic parameters were given accurate physical significance by comparing the relationship between the lognormal function and the exact hydration reaction rate. The dissolution process of magnesium oxide (peak I), the formation process of amorphous phase (peak II) and the formation process of phosphate minerals (peak III) of MKPC proceed sequentially, yet partially overlap, and the time of occurrence of the former process influences the latter process.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":19016,"journal":{"name":"MRS Communications","volume":"17 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139585685","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}
