Collaborative Research: Framework: Data: HDR: Nanocomposites to Metamaterials: A Knowledge Graph Framework

This collaborative project led by 5 academic institutions entails the ongoing development of an open-source, extensible, semantic cyberinfrastructure (CI) following FAIR principles for Materials research (MaterialsMine), with specific application to polymer nanocomposites (NanoMine) and metamaterials (MetaMine), comprising a database to store semi-automated curated data with associated data validation protocols, along with a Materials Knowledge Graph (KG) for ontology-enabled exploration, discovery, and design tools and custom user dashboards.

Recent enhancements in CI include a modularized reorganization of the backend for increased speed and performance, augmented KG flexibility pairing semantic context of metadata (SPARQL query) with visual context (Vega-Lite specification), and new search and visualization interfaces for users with varying levels of technical expertise. Concurrent development in image analysis, NLP-enabled curation, digital twin creation, and implementation of design tools for discovery of processing-structure-property relationships are also highlighted.
