The proposed research is intended to explain high resolution bioimaging problems addressed only phenomenologically before. A correct physical model would help the scientific community to optimise imaging of dynamic biological systems, extending our knowledge about the way living organisms function. With dynamic bioimaging, the mechanism of certain diseases such as Alzheimer's - where biomolecule fiber formation plays a key role - can also be addressed, thus the project has even therapeutical relevance. Furthermore, adequate description of liquid phase imaging can help engineers in the design of better hardware and software solutions, for the benefit of the bio-nanotechnological industry.Read moreRead less
Gamma-ray burst astronomy in the Swift era and beyond. The study of gamma-ray bursts is one of the most active and exciting fields in astrophysics, and touches on subjects that are of interest to all humans: e.g., to what extent was life on Earth shaped by cataclysmic explosions in our Galaxy? Australia's ROTSE-III telescope is the only facility in the southern hemisphere capable of rapidly (within 10 seconds) finding optical light from gamma-ray bursts. It will provide Australian astronomers ....Gamma-ray burst astronomy in the Swift era and beyond.

Australia's ROTSE-III telescope is the only facility in the southern hemisphere capable of rapidly (within 10 seconds) finding optical light from gamma-ray bursts.

The project will involve and inspire some of our best physics and engineering students.Read moreRead less
Foundation studies of ion-beam nanotechnology. The impact of a single fast atom with sensitive materials leaves a path of latent damage with a diameter of around 10 nm. This latent damage can be developed to create nanostructures in a novel technique called ion beam nanomachining. We propose to create a method for using single atom impacts to produce nanomachined structures with novel physical and optical properties. This will be done by use of an active substrate that functions as a detector s ....Foundation studies of ion-beam nanotechnology.

An ultra-wideband digital filterbank for the Mopra Radiotelescope. We seek funding to equip the Mopra radiotelescope with an ultra-wide-bandwidth digital filter bank. This will greatly improve the efficiency of the observatory, increasing the speed at which spectroscopic data is acquired by a factor of 8, and the speed of acquiring continuum data by a factor of 32. Once equipped in this way, Mopra, which is already the largest millimetre-wave radiotelescope in the southern hemisphere, will enjo ....An ultra-wideband digital filterbank for the Mopra Radiotelescope.

Once equipped in this way, Mopra, which is already the largest millimetre-wave radiotelescope in the southern hemisphere, will enjoy an unbeatable edge over all other competing observatories around the world through its combination of collecting area and bandpass.Read moreRead less

X-Ray Facility for 3-D High Resolution Diffraction Imaging of Nanostructures. Australian advances in quantitative x-ray imaging are at the leading edge of international efforts to permit 3D characterisation of the structure of materials and dynamic studies of structural changes. They have proven to be sensitive to local arrangement of materials at the nanometre scale, and they are emerging as critical tools in the development of advanced materials, which is a national research priority.

Australian advances in quantitative x-ray imaging are at the leading edge of international efforts to permit 3D characterisation of the structure of materials and dynamic studies of structural changes. They have proven to be sensitive to local arrangement of materials at the nanometre scale, and they are emerging as critical tools in the development of advanced materials, which is a national research priority. This facility will allow the non-destructive 3D imaging of nanostructured materials to be performed as continual experimental development - something that is very difficult to achieve at synchrotron sources where access can be sporadic. The newly developed techniques will be applied to critical problems in emerging nanotechnologies.Read moreRead less
Diffractive Imaging using Soft X-rays and Electrons. Optical, electron and x-ray microscopy has yielded enormous biological insights and medical benefits to society. Optical microscopy is able to image live tissue, but at relatively low resolution. Electron microscopy can yield high resolution images, but only of highly prepared material. X-ray microscopy yields images of live tissue with a resolution that is intermediate between optical and electron microscopy.

Electron microscopy can yield high resolution images, but only of highly prepared material. X-ray microscopy yields images of live tissue with a resolution that is intermediate between optical and electron microscopy. This project will provide Australian scientists with their first access to x-ray microscopy at its optimum wavelength; and secondly it will provide a superb testbed for x-ray microscopy to be enhanced using unique methods being developed in Australia.Read moreRead less

Two coherent thermal waves are input from two other surfaces of the prism in a similar way as an optical interferometer does. By inventing such a device, the project will demonstrate a new instrumentation mechanism which may lead to its application in medical technology. Furthermore, the principle of temperature localisation due to thermal interference may provide new insights to account for the cause of conformational changes of proteins that result in diseases.Read moreRead less
