Cornell University researchers have developed an artificial intelligence tool (AI) that aims to speed up the process of materials discovery.
In creating SARA (Scientific Autonomous Researching Agent for materials discovery and development), the researchers integrated robotic materials synthesis and characterization with a hierarchy of AI and active learning methods to uncover the structure of complex processing phase diagrams more quickly.
The researchers concentrated on inorganic materials that can be trapped in "metastable" states and potentially transformed to an "equilibrium" state over time.
SARA aims to reduce the amount of time and labor needed to identify metastable material from days to hours, and from hours to minutes.
Said Cornell's Michael Thompson, "The computer is controlling the experiment, in situ and live. There's a command to process material under particular conditions, and then immediately characterize it, and make a new decision about what the next experiment will be, based on the immediate new knowledge that's now available."
