Metal-Ligand Bonds02:51

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Tandem Mass Spectrometry01:21

Tandem Mass Spectrometry

Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...
Metallic Solids02:37

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability. Many...

Area of Science:

  • Materials Science
  • Computational Materials Science
  • Data Science

Background:

  • Sustainable materials design necessitates organized access to performance and sustainability data.
  • Existing data extraction methods using large language models (LLMs) often lack accuracy and scope.
  • High-entropy alloys (HEAs) present unique challenges for data extraction due to their complex compositions.

Purpose of the Study:

  • To develop an LLM-based pipeline for accurate and automated information extraction from HEA literature.
  • To create comprehensive databases of HEA compositions, processing, characterization, and properties.
  • To support sustainability-aware materials selection and design.

Main Methods:

  • An LLM-based pipeline employing prompt engineering and retrieval-augmented generation was developed.
  • The pipeline extracts data from both text and tables within scientific articles.
  • Databases were generated from over 10,000 HEA articles, containing millions of entries.

Main Results:

  • Achieved high F1-scores (~0.83 for text, ~0.88 for tables), surpassing existing methods.
  • Created the largest publicly available database for multicomponent alloys.
  • Identified compositional and processing-property trends and potential sustainable alloy candidates for specific applications.

Conclusions:

  • The developed pipeline enables accurate and efficient data extraction for sustainable materials design.
  • The generated HEA database facilitates the discovery of novel materials with improved sustainability.
  • The methodology is generalizable to other material classes, advancing materials informatics.
