From: Text-mined dataset of gold nanoparticle synthesis procedures, morphologies, and size entities
Breakdown of reported AuNP morphologies discussed by year. Similarly to the frequent precursors analysis, we compiled a regular expression-based synonym map for the most frequently extracted morphological entities and descriptors. The timeline represents the cumulative number of publications discussing each of the specified morphologies from 1998–2021. The entire plot represents 1,744 articles from the dataset, each of which discuss only one of the morphologies in the set depicted.
