AI总结:

本研究提出结合提示工程与材料体系图的大语言模型方法,可在无人类专家指导下整合多源科学原理生成可落地的材料设计假设,经实验验证其价值,为AI驱动材料发现开辟新路径。

摘要:

材料设计通常依赖人工提出的假设,这一过程固有地受到认知限制的制约,例如知识缺口、整合与挖掘知识内涵的能力有限,在需要多学科专业知识的场景中尤为突出。本研究表明,大语言模型(LLM)结合提示工程,能够整合不同来源的科学原理,在无需人类专家明确设计指导的情况下,有效生成有价值的非平凡材料假设。这些假设涵盖具备优异低温性能的高熵合金、以及离子电导率与成型性提升的卤化物固态电解质的设计思路。这些设计思路已在2023年的高影响力出版物中得到实验验证,且相关成果不在LLM的训练数据范围内,证明LLM能够生成文献中尚未确立的、极具价值且可落地的创新想法。我们的方法主要利用编码了加工-结构-性能关系的材料体系图,通过LLM浓缩大量论文的关键信息以实现更高效的数据整合,同时通过LLM对大量假设进行评估与分类,适配人类认知水平。这种LLM驱动的方法为人工智能驱动的材料发现开辟了新路径,能够加速设计进程、推动创新普惠,并拓展超出设计者直接知识范畴的能力边界。

英文摘要:

Materials design often relies on human-generated hypotheses, a process inherently limited by cognitive constraints such as knowledge gaps and limited ability to integrate and extract knowledge implications, particularly when multidisciplinary expertise is required. This work demonstrates that large language models (LLMs), coupled with prompt engineering, can effectively generate non-trivial materials hypotheses by integrating scientific principles from diverse sources without explicit design guidance by human experts. These include design ideas for high-entropy alloys with superior cryogenic properties and halide solid electrolytes with enhanced ionic conductivity and formability. These design ideas have been experimentally validated in high-impact publications in 2023 not available in the LLM training data, demonstrating the LLM's ability to generate highly valuable and realizable innovative ideas not established in the literature. Our approach primarily leverages materials system charts encoding processing-structure-property relationships, enabling more effective data integration by condensing key information from numerous papers, and evaluation and categorization of numerous hypotheses for human cognition, both through the LLM. This LLM-driven approach opens the door to new avenues of artificial intelligence-driven materials discovery by accelerating design, democratizing innovation, and expanding capabilities beyond the designer's direct knowledge.
