This project aims to establish a transmission electron microscope facility to analyse materials structure at the atomic level. A small number of atoms in critical locations governs the properties of materials from solar cells and catalysts to aerospace alloys, bio-sensors and quantum computers. To understand and engineer matter at this atomic level, tools are needed to characterise these critical atoms. This open access, national facility will be able to characterise matter at the atomic-level. Expected outcomes include better understanding of the natural world and advanced materials to solve problems in energy, technology, health, environment, communications, advanced manufacturing, transport and security.Read moreRead less

This project aims to establish a triple beam ion and electron microscope facility for the modification, preparation and characterisation of materials that have hitherto been too sensitive for high resolution analysis with charged particle beams. It is expected that materials will be studied artefact-free and at the nanoscale with twin ion beams and new detectors that allow novel imaging modes and extreme chemical sensitivity plus controlled atmosphere transfer to other instruments for correlative measurements. This unique facility should benefit research in many disciplines such as physics, chemistry, geology, pharmacy, materials, civil and chemical engineering by allowing first-ever observations of vital phenomena in diverse materials.Read moreRead less
Atomic scale imaging with high coherence electrons and ions. This project aims to combine a cold atom electron-ion source with a commercial microscope column for atomic-scale imaging in biosciences and materials science. Nanoscale imaging with electron and ion microscopy are tools for investigating the world at the atomic scale, underpinning development in modern technologies from semiconductor devices to medical treatments. This project will use ideas from laser cooling of atoms and atom optics ....Atomic scale imaging with high coherence electrons and ions.

Nanoscale imaging with electron and ion microscopy are tools for investigating the world at the atomic scale, underpinning development in modern technologies from semiconductor devices to medical treatments. This project will use ideas from laser cooling of atoms and atom optics to achieve new imaging modalities for time-lapse imaging of fundamental processes at the nano-scale. It will allow increasingly small scale resolution of fundamental processes at the nano-scale.Read moreRead less

Summary
The Giant Cuttlefish population in Spencer Gulf is the largest in the world and is highly valued by local residents, the tourism industry and the recreational diving sector. But surveys over the last 13 years has indicated that the northern population has, and continues to, decline markedly - leading to major public consternation.

But surveys over the last 13 years has indicated that the northern population has, and continues to, decline markedly - leading to major public consternation.
The Spencer Gulf Prawn Fishery is known as one of the best managed trawl fisheries in the world and is permitted to only land three species, the western king prawn, bugs and southern calamari
A recent SARDI study correlated the observed decline in Cuttlefish abundances with a range of potential factors including: water temperature, weather, pollution (including those from increased shipping activities), predators, prey, habitats, diseases, fishing pressure and tourism. Of these, rainfall was the only factor found to correlate inversely with peak cuttlefish abundance. The study noted the incidental capture of Giant Cuttlefish in the Prawn Fishery but found no clear association between the decline in cuttlefish and fishing intensity. The study noted a positive correlation between trawl effort and the size of the cuttlefish population but this relationship is counter-intuitive and is likely to be coincidental. The evidence therefore does not support an assertion that the recent decline in the abundance of Giant Cuttlefish in northern Spencer Gulf has been caused by prawn trawling or any other forms of fishing.
Nevertheless, due to the low population numbers, all sources of potential mortality of cuttlefish, including that from prawn trawl bycatch, need to be minimized urgently and carefully managed. This project is focused on an attempt to reduce the bycatch of cuttlefish in this fishery using modifications to the trawls used (termed ‘bycatch reduction devices’ or ‘BRDs’). If successful, such BRDs should be suitable for use in locations and at times where cuttlefish bycatches are significant.
Objectives: 1. To test four grid-based designs to determine the best way forward in developing a BRD for this fishery that excludes cuttlefish and crabs, yet does not reduce prawn catch by any more than approx 6% and has a negligible variation in the grade composition of prawns. Read moreRead less

Survey the lipid and fatty acid content of microalage to determine characteristic distributions for the major algal classes and to identify new species of use to the Australian mariculture industry, particularly in tropical hatcheries. 3. Identify the effects of different environmental conditions on fatty acid and lipid composition of microalgae by comparing cultures grown under a variety of defined conditions, and hence determine how to optimise fatty acid content . 4. Assess the effects of algal foods with different fatty acid contents on animal production in support of animal growth trial with bivalve molluscs, particularly the oyster Crassostrea gigas, carried out as part of FIRDC grant 90/063. 5. Identify the effects of various diets (rotifers and copepods) which have different fatty acid compositions on the growth and survival of fish larvae in support of experiments carried out by the staff from the Tasmanian Division of Sea Fisheries 6. Assist the fishing and mariculture industries with advice on the nutrition of marine organisms, and provide a service for the analysis of polyunsaturated fatty acids and other lipids in marine samples.
