Exploring structure-property correlations in advanced materials: Nexus between computational simulation and atomic resolution microscopyThis project aims to link the underlying structure of advanced materials to their properties. This is done through calculating specific properties of materials and comparing them to those experimentally observed. Often these calculations are used to predict specific properties without prior experimental domain knowledge. In this project, we aim to gain a more comprehensive understanding of the structure-property relationships, in order to enable rational materials design in the future for specific properties by controlling their structure.

The goal is to understand the underlying structure-property relationships in advanced materials. These include advanced engineering alloys (steels/Ni-base superalloys etc.), nanomaterials (nanowires, 2D materials), bulk metallic glasses, perovskite solar materials, and more.
By utilising computational simulations, we can calculate and predict material properties from a purely fundamental quantum mechanical basis. By comparing the calculated properties and cross-validating them with experimental results, we can gain a deeper understanding of the relationship between a material’s structure and its properties.
The utilisation of HPC resources is critical for handling the heavy computational loads required to simulate and predict materials properties.
