Core Viewpoint - The article discusses the establishment of the New Materials Big Data Center, which aims to support national strategies by focusing on resource aggregation, orderly circulation, and secure sharing of data to promote original innovation in new materials and facilitate the development of new materials technology and industry [2]. Group 1: Overview of the New Materials Big Data Center - The New Materials Big Data Center is positioned as a new type of R&D infrastructure to promote innovation in new materials technology and industry, with a focus on public welfare, authority, internationalization, and sustainability [2]. - The center adopts a "1+N" architecture system, consisting of one main platform and multiple data resource nodes, to facilitate the integration and application of material data across technology and industry [2]. Group 2: Portal Development and Features - The unified service portal (test version) for the New Materials Big Data Center is set to launch on May 6, 2025, and will solicit feedback from the public to enhance service quality [2][4]. - The portal includes functionalities such as material data retrieval, data products, R&D applications, supply-demand services, and ecological development [3]. Group 3: Data Retrieval and Services - Users can perform full-text searches using keywords or filter by material category and data source, with some data on metallic materials available for testing during the feedback period [6][7]. - The data products module offers 16 types of specialized data samples and 8 data tool software for testing, with plans for further updates and product offerings [9]. - The demand service section provides users with services such as demand collection, supply-demand matching, and case studies, with future enhancements planned for data sharing and interaction [11]. Group 4: Collaboration and Feedback - The portal will facilitate various academic and industry collaboration activities, including conferences, journals, international exchanges, and talent training, to build a thriving new materials big data ecosystem [13]. - The center will collect feedback on the portal's architecture, design, functionality, and content for three months after the test version launch to improve service quality [14].
