This study investigated the in vitro effects of ZnO NP and chemical UV filters commonly used sunscreens on the function of immortalised and primary skin cells. ZnO particulates (30 nm, 80 nm and 200 nm) were compared to the chemical UV filters: butylmethoxydibenzoylmethane (BMDBM) ethylhexylmethoxycinnamate (EHMC), ethylhexylsalicylate (EHS), homomenthylsalicylate (HMS) and 4-methylbenzylidenecamphor (MBC). Human epidermal keratinocytes (NHEK), epidermal melanocytes (NHEM), dermal fibroblasts (NHDF) and the immortalised keratinocyte HaCaT cell line were used in this study.

The document will be structured as follows: In Chapter 2 outline the methodology, discussing the computational techniques used to evaluate the interaction energies and evaluating the construction of the TT and D3(BJ) correction terms. Chapter 3 attempts to establish a foundational understanding of how these methods model vdW interactions by evaluating the performance of the corrected and uncorrected HF and DFT methods in comparison with CCSD(T) energies for a selection of inert gas dimers, and simple molecule-molecule interactions.

The objective of this thesis is to examine the practice of infrastructure procurement in Australian State Governments in order to analyse how strategic the procurement function is. In doing so this thesis examines how Australian State Government agencies procure infrastructure projects and the extent to which they view the procurement process as an opportunity to deliver more than just a physical facility. This research contributes to both the body of knowledge focused on maximising the impact of public sector expenditure and the practice of infrastructure procurement.
