  • Evaluate and rank AI-generated answers.
  • Write precise feedback, technically accurate rewrites, and model answers.
  • Check scientific accuracy, engineering reasoning, terminology, clarity, physical plausibility, and unit consistency.
  • Review microstructure-property relationships and interpretations of experiments.
  • Identify hallucinated properties, flawed processing advice, incorrect diagrams, unsafe design assumptions, unsupported performance claims, and overconfident interpretations.
  • Fact-check technical claims and apply detailed review guidelines consistently across repeated tasks.
