In this project, EXtreme-scale Electronic Structure Systems (EXESS) will be used to perform extreme-scale ab initio quantum chemical calculations for many different bio-relevant molecules at the nanomaterial interface, specifically including molecular systems with up to thousands of atoms as a template. More specifically, we will focus on the interfacial chemistry of boron nitride (BN), which is an ideal example of a solid material that has a multitude of current and possible new uses in industrial processes.
The extreme-scale ab initio calculations will be used to obtain, for the first time, a definitive benchmark of interfacial adsorption energies and geometries for a suite of small molecules adsorbed on boron nitride surface that are relevant to addressing grand-challenge scientific questions in a wide range of industrially-relevant areas, including energy generation, nanomedicine, and water purification.
This project will collaborate closely with a large, world-class team of electronic structure theory developers in applying new EXESS to studying these nanomaterial interfaces.

Molecular modelling of bio-based self-healing polymers
This project will use molecular dynamics simulations to model the structure and properties of bio-based self-healing resins, particularly those involving dynamic bonding (including hydrogen bonding). There is a growing focus in the resin area to develop bio-based alternatives to petroleum-based resin products. However, bio-based analogues can suffer from performance issues and the reasons to explain this are not always clear, due to the relative immaturity of these materials in comparison to their petroleum-based counterparts. Molecular simulations can predict the molecular-scale structure of these materials and enable clear links to their physical properties. In this project, a range of bio-based self-healing polymers will be considered, including Schiff-based polymers and bio-derived polyols for making bio-based polyurethanes. The insights from these molecular simulations will provide a strong complement to parallel experimental activities led by Prof Russell Varley.
Applicants are encouraged to contact Prof Walsh as soon as possible at tiffany.walsh@deakin.edu.au. Due to the high volume of applications, applicants who do not meet the candidate specifications below cannot be guaranteed a reply.

Investigating the impacts of environmentally relevant microplastic exposures on iconic wetland biota in a multi-stressor context
Application Deadline :Wednesday, February 02, 2022
Funded PhD Project (Students Worldwide)
It is now well established that MPs are ubiquitous global pollutants. However, evidence of harm is lacking since there is a mismatch between laboratory exposures to virgin/unweathered MPs of a single type and heterogenous MP assemblages found in natural systems. This has led to the potential toxicity of MPs to biota being extremely poorly defined, thereby hindering effective risk assessment. Biodiversity loss is occurring at an alarming rate and associations between declines and multiple interacting stressors have been demonstrated from a wide range of taxa, including insects, amphibians, birds and fish. Multiple stressors negatively impact the stability of entire ecosystems through alterations in species interactions. These effects are particularly pertinent for FW systems, which are amongst the most threatened on Earth, and which are predicted to lose 80 % of their biodiversity as a result of multiple stressors by 2050. However, the potential interactions of MPs with other ubiquitous environmental stressors remain virtually unknown. The aim of this project, therefore, is to investigate the effects of MPs in a multi-stressor context on freshwater biota (common frog, Rana temporaria).
