Computational Studies of Nanostructures for the Development of Nanosensors


Calculations will be carried out to characterise and study nanostructures, and to assist in the development of new nanosensors. The structures that will be initially investigated will be graphene-based. Computational studies will include: ab initio studies of molecular interactions; development of density functional theory to treat interactions between carbon nanotubes and structures; study of interactions of adsorbates with nanostructures; study of fluid flow in nanostructures; and characterisation and interpretation of experimental data on nanostructures and adsorbed molecules.

Significant Achievements, Anticipated Outcomes and Future Work

Molecular interactions of monomers with models of graphite-like systems and carbon nanotubes have been considered using ab initio calculations; and modelling. Various approaches have been tested using Ne as the monomer and new potential surfaces have been developed. The results have allowed an approach for efficient determination of interaction potentials to be proposed. This work was presented at the RACI National Convention in Sydney, July 2005 and is being prepared for publication.
