ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 7.5. The functionality has changed, but the content remains the same.

ANSTO Publications Online is a digital repository for publications authored by ANSTO staff since 2007. The Repository also contains ANSTO Publications, such as Reports and Promotional Material. ANSTO publications prior to 2007 continue to be added progressively as they are in identified in the library. ANSTO authors can be identified under a single point of entry within the database. The citation is as it appears on the item, even with incorrect spelling, which is marked by (sic) or with additional notes in the description field.

If items are only held in hardcopy in the ANSTO Library collection notes are being added to the item to identify the Dewey Call number: as DDC followed by the number.

APO will be integrated with the Research Information System which is currently being implemented at ANSTO. The flow on effect will be permission to publish, which should allow pre-prints and post prints to be added where content is locked behind a paywall. To determine which version can be added to APO authors should check Sherpa Romeo. ANSTO research is increasingly being published in open access due mainly to the Council of Australian University Librarians read and publish agreements, and some direct publisher agreements with our organisation. In addition, open access items are also facilitated through collaboration and open access agreements with overseas authors such as Plan S.

ANSTO authors are encouraged to use a CC-BY licence when publishing open access. Statistics have been returned to the database and are now visible to users to show item usage and where this usage is coming from.

Real-space nanostructure via correlation analysis of scanning microfocus x-ray diffraction data
(ScienceOpen, 2025-02-02) Paporakis, S; Hasset, MP; Adams, P; Binns, J; Kewish, CM; Christofferson, AJ; Greaves, TL; Martin, AV
Fluctuation scattering techniques (also known as x-ray cross-correlation analysis techniques) aim to extract 3D structural information from scanning diffraction experiments via statistical analysis methods, typically based on correlating diffracted intensities [ 1]. There are opportunities to study the nanostructure of disordered and polycrystalline materials, nanoparticle assemblies [ 2] and to image viruses and nanoparticles [ 3]. These methods use similar microfocus or nanofocus beam conditions to ptychography and spectroscopic mapping techniques and represent a route to add new capabilities to existing spectromicroscopy beamlines. A key challenge for fluctuation scattering methods is interpreting the results in terms of real space structure [ 1]. Here we present different approaches for interpreting fluctuation scattering results in real-space. As shown in Fig. 1, for disordered samples it is possible to extract the pair-angle distribution (PADF) function which is higher order form of the well-known pair-distribution function [ 4, 5]. We explain how the PADF can reveal 3D nanostructural information in highly disordered materials and show examples from thermotropic and lyotropic liquid crystals [ 6]. For polycrystalline materials we show how, depending on beam size and domain size, we can gain insights into the microtexture (orientation distribution of the grains) or the structure of the unit cell [ 7]. We also present an algorithm that can extract crystallographic structure factors to provide a route to structure determination via correlation analysis [ 8]. There is significant potential to grow these capabilities in a way that is complimentary to existing imaging and mapping techniques, and which may allow access to nanostructural information that is otherwise inaccessible.

Pharmacological evaluation of a novel 18F-benzamide with high uptake and specificity to melanotic tissues as a PET diagnostic agent for melanoma
(Wiley, 2013-05) Berghofer, PJ; Taylor, SR; Ballantyne, P; Pham, TQ; Loc’h, C; Wyatt, NA; Nguyen, VH; Denoyer, D; Hicks, RJ; Grégoire, MC; Katsifis, A; Greguric, ID
With distinct increases in incidence and mortality of melanoma worldwide our objective was to prepare radiolabel and evaluate [18F]MEL054; an enticing novel melanin targeting PET radiopharmaceutical whose characteristics have been taken from our previously reported iodinated molecules [123I]MEL037 and [123I]MEL008. As the chemistry of [18F]MEL054 can be simply translated to an iodine based [131I]radiopharmaceutical this is our first phase in creating an effective diagnostic/therapeutic pair targeting metastatic melanoma. © Wiley

Evaluation of residual stress in self-pierce riveted joints by neutron diffraction and transmission measurements
(Australian Nuclear Science and Technology Organisation, 2013-09-10) Haque, R; Paradowska, AM; Tremsin, AS; Durandet, Y
Self-Pierce Riveting (SPR) is a mechanical fastening technique for joining sheet materials. it is increasingly replacing resistance spot welding in the automotive industry for the assembly of lightweight structures made of advanced or dissimilar materials that are difficult and sometimes impossible to join by welding. The production of joints by SPR involves high pressures and large plastic deformation at high strain rate in both the sheets materials and the rivets. Knowledge of the resulting state of stress in the materials is important to understanding the performance of the joints. In this work, the challenges and uncertainties involved in measuring residual stresses in SPR joints using the neutron diffraction and transmission techniques are discussed. Even though small sizes were involved, meaningful results were obtained, and measurement errors were reduced by optimising instrument parameters.

Accelerator based anaylytical techniques for analysis of aerosol filters
(INSTN Institut national des sciences et techniques nucléaires, 1993-05-17) Cohen, DD; Bailey, GM; Martin, JW
The ion beam analysis techniques, Particle Induced X-ray Emission (PIXE), Particle Induced Gamma-ray Emission (PIGME), Particle Elastic Scattering Analysis (PESA) and Rutherford Backscattering Spectrometry (RBS) for 2.6 MeV protons, have been developed to operate simultaneously on a 3 MV Van de Graaff accelerator to analyse aerosol filter papers. PESA is used in the forward scattering mode at 30° to determine the total H content. RBS at 169° is used to determine C, N and O content of the thin filter papers. PIGME is used to determine light elements such as F and Na and PIXE is used for all elements above Al. The system has high sensitivities, is non destructive and can analyse 12 samples/hour. Comparisons of these IBA techniques with neutron activation analysis (NAA) and ion chromatography (IC) will be made.

Heavy ion recoil spectrometry of barium strontium titanate films
(Australian Institute of Nuclear Science and Engineering, 1995-02-01) Stannard, WB; Johnston, PN; Walker, SR; Bubb, IF; Scott, JB; Cohen, DD; Dyltewski, N
Ferroelectric films are being developed for use in DRAMs. However some commercially promising materials suffer fatigue problems that are likely to be related to stoichiometric changes. Heavy ion recoil spectrometry employing 77 and 98 MeV 127I ions has been used to analyse thin films of barium strontium titanate (BST) at the new heavy ion recoil facility at ANSTO, Lucas Heights. The technique employs a Time of Flight and Energy (TOF-E) detector which enables the determination of separate energy spectra for individual or small groups of elements. Depth profiles for all major elements and carbon have been obtained. Analysis reveals depletion of oxygen in the BST layer next to the platinum electrode and interdiffusion of strontium and oxygen through the layers.
