TribChem: A Software for the First-Principles, High-Throughput Study of Solid Interfaces and Their Tribological...

Area of Science:

• Computational Materials Science
• Tribology
• Quantum Mechanics

Background:

• High-throughput first-principles calculations are vital for materials technologies like batteries and hydrogen storage.
• Systematic study of solid-solid interfaces and their tribological properties using these methods has been limited.

Purpose of the Study:

• To introduce TribChem, an advanced software program designed for high-throughput calculations of solid-solid interfaces.
• To enable systematic investigation of tribological properties at the nanoscale.

Main Methods:

• Development of TribChem, a modular software based on the FireWorks platform.
• Parallel computation of quantum mechanical many-body problems for materials.
• Calculation of bulk, surface, and interface properties, including adhesion, shear strength, and charge redistribution.

Main Results:

• TribChem successfully calculates key interfacial properties such as adhesion, shear strength, and charge redistribution.
• The software's modular design allows for easy addition of new property calculations.
• A high-level interface class facilitates data management and integration with public databases.

Conclusions:

• TribChem provides a powerful and extensible platform for advancing the understanding of solid-solid interface tribology.
• The software facilitates high-throughput computational studies, accelerating materials discovery and design for tribological applications.
