Peptide-Directed High Entropy Nanomaterials Established via Structure-Function Relationships

Abstract

The main objective of this project is to understand how peptides can be used to guide the synthesis of high entropy alloy (HEA) nanoparticles with optimized properties. By using synchrotron characterization techniques that probe atomic-scale structure in an element specific fashion, the fundamental science needed to better understand the influence of peptide sequence on atomic scale structure and chemical miscibility will be uncovered for downstream property optimization, including optical, magnetic, and catalytic properties. Peptide-enabled HEAs will be synthesized at UNSW, along with property evaluation and electron microscopy experimentation. Synchrotron facilities in the US, Europe, and Australia to perform synchrotron X-ray spectroscopy and diffractions experiments that will then be used to build atomic-scale structure models using stochastic modelling techniques. HEA structure models enable the construction of synthesisstructure-property relationships, enabling new design routes for HEAs with enhance-emergent properties. Successful outcomes from the proposed study will establish fundamental design principles for synthesizing of HEAs using peptides, opening up pathways for new materials for use in a wide range of applications of importance to the DoD.
