In July this year, the NASA New Horizons spacecraft completed an historic flyby of the Plutonian system, the first spacecraft to visit Pluto. The long-awaited data from this mission will take months to be returned in full to Earth. However, the wealth of data received so far, although small in volume, is already providing amazing insights into the surface morphology and geochemistry of Pluto...

The orientation of molecules within thin films is of critical importance to the emerging field of organic electronics. Particularly in the case of solution processable polymers and small molecules, where alkyl side chains, included for solubility, impede conduction along that molecular direction, understanding and controlling the molecular orientation both at surfaces and in the bulk of thin...
21. Quantitative Femtosecond Charge Transfer Dynamics at Organic/Electrode Interfaces Studied by Core-Hole Clock Spectroscopy
Dr Dongchen Qi (Department of Chemistry and Physics, LIMS, La Trobe University)
Organic semiconductors have important applications in organic electronics and other novel hybrid devices. In these devices, the transport of charge carriers across the interfaces between organic molecules and electrodes plays an important role in determining the device performance. Charge transfer dynamics at these interfaces usually occurs at the several femtoseconds timescale which presents...

Quantum technologies promise exciting and transformative futures in many areas of human endeavour. An example is the field of bio-sensing, where quantum probes are already being used to answer fundamental questions about living cells. In these applications diamond often takes centre stage, as a material which simultaneously exhibits both bio-friendly and quantum-friendly properties. This...

Thermoelectric materials directly convert thermal energy into electrical energy, offering a green and sustainable alternative for the global energy market.[1, 2] So far, extensive investigations have been made to improve the thermoelectric efficiency, which governed by the dimensionless figure-of-merit ZT ( ), where σ is the electrical conductivity, S is the Seebeck coefficient, T is the...

Epitaxial graphene grown using solid source carbon from silicon carbide wafers has been for long time the only route to obtain high quality graphene directly grown at the wafer –level, which is crucial to realise the promise of graphene for nanodevices. Nonetheless, the capability of obtaining comparable quality of graphene on silicon as opposed to silicon carbide wafers, would open an immense...
69. Atomic-scale understanding of CO2 adsorption processes in metal-organic framework (MOF) materials using neutron scattering and ab initio calculations
Josie Auckett (ANSTO)
The dependence of the industrialised world on fossil-fuel energy generation technologies and consequent increase in atmospheric CO2 concentrations has been blamed for emerging adverse climate effects, including an increase in global mean temperatures . Until renewable, carbon-free energy sources can be efficiently harnessed to meet the world’s energy needs, interim measures are...
106. X-radiation in health and disease: Novel approaches to the study of disease processes and therapy
Prof. Damian Myers (The University of Melbourne)
Our current medical knowledge and understanding of human biology and physiology have been predicated by our capacity to image organs, body structures, different types of tissues and particular cell types. These imaging modalities range from advanced microscopy for imaging of cells and tissues through to 2D and 3D macroscopic techniques for imaging of tissues and organs. Soft tissues in...

Interfacial control of a polar (rhombohedral)-to-non-polar (orthorhombic) phase transition in (001) oriented epitaxial BiFeO3/(Bi1-xSmx)FeO3 superlattices is presented. We demonstrate controlling the composition at which a polar phase transformation takes place by tuning the strength of the interlayer interactions while holding the average composition constant. It is shown that the thickness...
Dr Tapio Simula (Monash University)
Lars Onsager is perhaps best known as the recipient of 1968 Nobel Prize in chemistry and by his tour de force solution to the two-dimensional Ising model. However, his remarkable insight predicting the quantisation of vorticity in superfluid helium and the statistical mechanics description of two-dimensional turbulence have received much less attention. In this talk, I will briefly review...
