The Australian Centre for Neutron Scattering operates a suite of 15 neutron instruments distributed across the thermal- and cold-sources of the OPAL reactor, ANSTO. Two of the cold instruments are optimized for quasielastic neutron scattering measurements.
　　This presentation will highlight the scientific capabilities of the EMU neutron backscattering spectrometer enabling access to microscopic, molecular dynamics up to about 5 ns time scale. Investigations of diffusive processes in organic materials are the primary strength area for such spectrometers. Thus examples from biophysics and polymer science will be presented. In particular, results from a recent hemoglobin dynamics study will be outlined. There is also growing interest in understanding transport-related diffusion in inorganic materials related to energy applications. In this area we will highlight our ongoing effort towards elucidating sodium diffusion in specific solid-state ionic conductors.
