Exploiting the properties of gold nanoparticles for nanolithography using visible wavelengths. The next generation of nano-devices, such as biosensors and molecular electronics, will require nanopatterning as part of the production process. Conventional optical lithographies cannot provide sufficient resolution, and alternative techniques, such as e-beam lithographies are expensive. This project aims to demonstrate a solution to this problem with obvious commercial benefit.

The next generation of nano-devices, such as biosensors and molecular electronics, will require nanopatterning as part of the production process. Conventional optical lithographies cannot provide sufficient resolution, and alternative techniques, such as e-beam lithographies are expensive. This project aims to demonstrate a solution to this problem with obvious commercial benefit. It is the first time a multidisciplinary team has made such a concerted effort to understand the unusual science of gold nanoparticles and will strengthen Australia's already considerable reputation in this field.Read moreRead less
Hirshfeld surfaces in molecular crystals: Revolutionary tools for crystal engineers. Crystal engineering is an exciting modern branch of chemistry that seeks to understand intermolecular interactions in the context of crystal packing, and to use this understanding in the design of new materials with desirable physical and chemical properties. This project will considerably extend our already significant contribution to the detailed analysis of intermolecular interactions in molecular crystal st ....Hirshfeld surfaces in molecular crystals: Revolutionary tools for crystal engineers. Crystal engineering is an exciting modern branch of chemistry that seeks to understand intermolecular interactions in the context of crystal packing, and to use this understanding in the design of new materials with desirable physical and chemical properties. This project will considerably extend our already significant contribution to the detailed analysis of intermolecular interactions in molecular crystal structures. It will achieve this by a substantial enhancement of our novel visualization tools, by improving upon current approaches to the analysis of theoretical and experimental crystalline electron distributions for molecular materials, and by ensuring the widespread availability of resulting software to all researchers.Read moreRead less
Nonlinear optical properties of molecular crystals: An innovative approach to their determination using high-resolution X-ray diffraction data. This project will make a novel contribution towards the creation and optimisation of new optically-active materials, an objective central to future photon science and information technology. By developing and implementing innovative approaches in the charge density analysis of high-resolution, low-temperature single-crystal X-ray diffraction data, we wil ....Nonlinear optical properties of molecular crystals: An innovative approach to their determination using high-resolution X-ray diffraction data. This project will make a novel contribution towards the creation and optimisation of new optically-active materials, an objective central to future photon science and information technology. By developing and implementing innovative approaches in the charge density analysis of high-resolution, low-temperature single-crystal X-ray diffraction data, we will obtain in-crystal estimates of the electronic part of molecular (hyper)polarisabilities and related bulk susceptibilities, for crystals of selected important organic nonlinear optical (NLO) materials. The program will exploit advances in CCD technology for X-ray data collection, procedures for electron density and wavefunction fitting, and analysis of molecular dynamics in crystals.Read moreRead less
