ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 8.3. 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.

    Interdependence of slurry erosion wear performance and residual stress in WC-12wt%Co and WC-10wt%VC-12wt%Co HVOF coatings
    (Elsevier, 2020-02) Venter, AM; Luzin, V; Marais, D; Sacks, N; Ogunmuyiwa, EN; Shipway, PH
    High-velocity-oxygen-fuel deposited WC-12wt%Co and WC-10wt%VC-12wt%Co hardmetal coatings are well anchored to the mild steel substrates, giving good mechanical integrity, as well as low porosity. The mechanical integrity has been investigated in terms of erosion performance and its influence on the residual stress state in the eroded regions. Wear slurry erosion tests reveal similar rates of erosion for both systems, that becomes more severe as the impact angle increases due to higher direct impact deformation normal to the surface. The 10wt%VC-12wt%Co coating renders slightly better erosion performance throughout. Stress evaluations using X-ray and neutron diffraction reveal substantial compressive residual stresses in the WC-phases for both coating compositions in their as-coated conditions. Within their erosion scars, the stresses become more compressive with erosion angle due to the increased impact component normal to the surface. It is concluded that the better wear performance of the WC-10wt%VC-12wt%Co coatings with impact angle, correlates with larger induced in-plane compressive stresses in the WC phase. © 2019 Published by Elsevier Ltd.

    Adsorption geometry and electronic structure of iron phthalocyanine on Ag surfaces: A LEED and photoelectron momentum mapping study
    (Elsevier, 2014-03) Feyer, V; Graus, M; Nigge, P; Wießner, M; Acres, RG; Wiemann, C; Schneider, CM; Schöll, A; Reinert, F
    We present a comprehensive study of the adsorption behavior of iron phthalocyanine on the low-index crystal faces of silver. By combining measurements of the reciprocal space by means of photoelectron momentum mapping and low energy electron diffraction, the real space adsorption geometries are reconstructed. At monolayer coverage ordered superstructures exist on all studied surfaces containing one molecule in the unit cell in case of Ag(100) and Ag(111), and two molecules per unit cell for Ag(110). The azimuthal tilt angle of the molecules against the high symmetry directions of the substrate is derived from the photoelectron momentum maps. A comparative analysis of the momentum patterns on the substrates with different symmetry indicates that both constituents of the twofold degenerate FePc lowest unoccupied molecular orbital are occupied by charge transfer from the substrate at the interface. © 2013 Elsevier B.V.

    Influence of WC particle size on the mechanical properties and residual stress of HVOF thermally sprayed WC–10Co–4Cr coatings
    (MDPI, 2022-08-11) Fan, KY; Jiang, WH; Luzin, V; Gong, T; Feng, W; Ruiz-Hervias, J; Yao, PP
    Cermet coatings deposited using high-velocity oxy-fuel (HVOF) are widely used due to their excellent wear and corrosion resistance. The new agglomeration–rapid sintering method is an excellent candidate for the preparation of WC–Co–Cr feedstock powders. In this study, four different WC–10Co–4Cr feedstock powders containing WC particles of different sizes were prepared by the new agglomeration–rapid sintering method and deposited on steel substrates using the HVOF technique. The microstructures and mechanical properties of the coatings were investigated using scanning electron microscopy, X-ray diffraction, nanoindentation, and Vickers indentation. The through-thickness residual stress profiles of the coatings and substrate materials were determined using neutron diffraction. We found that the microstructures and mechanical properties of the coatings were strongly dependent on the WC particle size. Decarburization and anisotropic mechanical behaviors were exhibited in the coatings, especially in the nanostructured coating. The coatings containing nano- and medium-sized WC particles were dense and uniform, with a high Young’s modulus and hardness and the highest fracture toughness among the four coatings. As the WC particle size increased, the compressive stress in the coating increased considerably. Knowledge of these relationships enables the optimization of feedstock powder design to achieve superior mechanical performance of coatings in the future. © 2022 by the authors.

    Synchrotron-infrared microspectroscopy of live leishmania major infected macrophages and isolated promastigotes and amastigotes
    (American Chemical Society (ACS), 2023-02-14) Chakkumpulakkal Puthan Veettil, T; Duffin, RN; Roy, S; Vongsvivut, JP; Tobin, MJ; Martin, M; Adegoke, JA; Andrews, PC; Wood, BR
    The prevalence of neglected tropical diseases (NTDs) is advancing at an alarming rate. The NTD leishmaniasis is now endemic in over 90 tropical and sub-tropical low socioeconomic countries. Current diagnosis for this disease involves serological assessment of infected tissue by either light microscopy, antibody tests, or culturing with in vitro or in vivo animal inoculation. Furthermore, co-infection by other pathogens can make it difficult to accurately determine Leishmania infection with light microscopy. Herein, for the first time, we demonstrate the potential of combining synchrotron Fourier-transform infrared (FTIR) microspectroscopy with powerful discrimination tools, such as partial least squares-discriminant analysis (PLS-DA), support vector machine-discriminant analysis (SVM-DA), and k-nearest neighbors (KNN), to characterize the parasitic forms of Leishmania major both isolated and within infected macrophages. For measurements performed on functional infected and uninfected macrophages in physiological solutions, the sensitivities from PLS-DA, SVM-DA, and KNN classification methods were found to be 0.923, 0.981, and 0.989, while the specificities were 0.897, 1.00, and 0.975, respectively. Cross-validated PLS-DA models on live amastigotes and promastigotes showed a sensitivity and specificity of 0.98 in the lipid region, while a specificity and sensitivity of 1.00 was achieved in the fingerprint region. The study demonstrates the potential of the FTIR technique to identify unique diagnostic bands and utilize them to generate machine learning models to predict Leishmania infection. For the first time, we examine the potential of infrared spectroscopy to study the molecular structure of parasitic forms in their native aqueous functional state, laying the groundwork for future clinical studies using more portable devices. © 2023 American Chemical Society

    Development of the slope cutting method for determining the residual stresses in roll formed products
    (Elsevier, 2017-03) Sun, Y; Luzin, V; Daniel, WJT; Meehan, PA; Zhang, MX; Ding, SC
    The residual stresses in a roll formed product play a critical role in determining the product quality. They are generally very complex and frequently difficult to predict due to the complicated fabricating process and its parameters. Consequently, they attract many concerns from roll forming scholars and engineers. However, how to inspect the residual stresses in roll formed products efficiently and economically is still a challenge. This paper introduces a novel, highly efficient, operationally simple and accurate residual stresses measurement method for evaluating the residual stresses in roll formed products. It utilizes a modification of the current sectioning methods to firstly obtain the membrane and bending residual stresses components. Then a novel material removal approach, the tapered removal, is employed to determine the layering stresses component by measuring the curvature variations of the remaining sample through its thickness direction. A practical implementation of the method is performed through the residual stresses measurement of a typical roll formed square hollow section (SHS). The method is successfully verified by the neutron diffraction method. The new method is expected to become a routine measuring method to determine the residual stresses distribution in roll formed products, with potentially significant impact on the roll forming industry. © 2016 Elsevier Ltd.
