We provided text from materials science literature each section at a time. The comprehensive instructions instructed the assistant to treat each section independently, focusing solely on its content without referencing or recalling information from other sections it has seen before. The goal was to meticulously convert each excerpt into a structured JSON format, treating each section as a distinct entity. The annotated data includes various entities found in materials science texts, such as chemical compositions, processing conditions, characterization methods, and performance properties accompanied by specific measurement conditions.
