That scientists must manually choose every recipe, execute every synthesis step, interpret each XRD result, and plan the next experiment.
Collections: Embodied work
Executive brief
Autonomy came from closing the loop between prediction, physical execution, measurement, and replanning; the 37% miss rate shows why scientist validation remains part of the system.
AI value · Target compounds synthesized
Verified36 of 57 target compounds synthesized, a 63% success rate
Research demonstration rather than routine production; 21 targets were not realized and final patterns were manually refined.
Before
Select a target and design a synthesis recipe from literature and thermodynamics. → Dose, mix, heat, characterize, and interpret each experiment.
After
Propose recipes and execute powder dosing, heating, and XRD characterization. → Assess phase yield and propose a new reaction path after failure. → Select target space, audit outputs, manually refine final diffraction patterns, and diagnose system failure modes.
Human boundary
The platform selects follow-up recipes inside the target set; scientists define targets and perform final validation.

Work that left the path
Human role before
Scientists and technicians planned and executed each experimental cycle.
Human role after
Scientists define the search space and validate findings while the platform runs repeated synthesis-characterization cycles.
AI role
Literature-trained recipe generation, XRD interpretation, and active learning connected to robotic execution.
