What to know about AI-driven literature mining speeds discovery of heat-stable lead-free dielectric materials

Researchers at Seoul National University have developed an AI-driven framework that combines multimodal literature mining with physics-informed machine learning to discover lead-free dielectric materials. The team successfully narrowed 150 million possibilities down to 37 candidates, experimentally validating two materials with high temperature stability and dielectric constants.
