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.

    LET calibration of ion microbeams and their SEE cross section characterization
    (Institute of Electrical and Electronics Engineers (IEEE), 2024-08-01) Peracchi, S; Drury, R; Pastuovic, Z; Williams, J; Tran, LT; Guatelli, S; Pan, VA; Archer, JW; Rosenfeld, AB; Coronetti, A; Emriskova, N; Alía, RG; Button, DT; Mann, M; Cohen, DD; Brenner, CM
    The Australian Nuclear Science and Technology Organisation hosts the Center for Accelerator Science, a sovereign facility with light and heavy ion beams. The 10-MV ANTARES accelerator is equipped with one of the few heavy ion nuclear microprobes in the world, which has been upgraded with the unique external beam irradiation facility (EBIF). EBIF has been actively used in the past few years for space radiation testing of electronics, advanced shielding materials, and living samples for life science in space. To align with international standards for such testing, a series of tests were performed to evaluate the uniformity of the raster scan of the microbeam across broad areas. Second, EBIF has been calibrated in terms of direct linear energy transfer (LET) measurement by using a silicon on insulator microdosimeter developed by the Centre for Medical Radiation Physics (CMRP), University of Wollongong. Third, in collaboration with researchers from European Organization for Nuclear Research (CERN), energy calibration and single-event effect (SEE) cross section measurements were performed with a silicon diode and a commercial static random-access memory (SRAM), which were evaluated in other international facilities. This article discusses experimental data obtained during the tests and their comparison with GEANT4 and stopping and range of ions in matter (SRIM) simulations. © Copyright 2026 IEEE - All rights reserved.

    Durability of hot uniaxially pressed Synroc derivative wasteform for EURO-GANEX wastes
    (Elsevier, 2018-10) Hsieh, YH; Humphry-Baker, SA; Horlait, D; Gregg, DJ; Vance, ER; Lee, WE
    A new titanate wasteform, Synroc-Z, was developed to contain minimal host phases for actinides and thus better suit the EURO-GANEX process. The processing conditions, waste loading and surface roughness were varied, and their effects on wasteform durability and microstructure were examined. Hot uniaxial pressing temperature was the most important factor in controlling density (<0.5 vol% porosity) and phase composition. Synroc-Z was found to have similar aqueous durability to Synroc-C. Leached samples formed Ti-oxide films and crystals on their surfaces as found by other researchers. At low waste loadings (<20 wt%), Synroc-Z showed slightly poorer durability performance than Synroc-C owing to its greater perovskite content (30 vs. 20 wt% respectively). However, at 35 wt% waste loading, Synroc-Z maintained its durability performance. This result is explained by the higher volume fraction of buffer phase, rutile, which allows greater flexibility for waste loading. © 2018 Elsevier B.V. All rights reserved.

    SANS/SAXS study to unravel the protein corona dynamics using deuterated human serum albumin interactions with plasmonic Au nanostructures
    (American Chemical Society (ACS), 2025-10-10) Tukova, A; Whitten, AE; Duff, AP; Laux, V; White, JW; Rodger, A; Wang, YL; Garcia-Bennett, AE
    Protein corona (PC) significantly influences the stability and biological interactions of nanoparticles and has a dynamic behavior, particularly with respect to the exchange between the “soft” (loosely bound) and “hard” (tightly bound) PC layers. This study employs small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) to investigate the structural and dynamic aspects of interactions of human serum albumin (HSA) with gold nanoparticles and gold nanostars. We utilized recombinant deuterated human serum albumin (dHSA) to enhance neutron contrast, enabling in situ tracking of protein binding and exchange without altering the protein structure or function. As a control, recombinant nondeuterated HSA (nHSA) was used to assess dynamic protein exchange. Structural characterization confirmed similar interactions of dHSA and nHSA with gold surfaces, ensuring reliability in PC dynamics studies. SAXS characterization revealed minimal protein binding to gold nanostars (AuNSs), suggesting a reduced propensity for PC formation compared with spherical gold nanoparticles (AuNPs). SANS measurements, conducted under contrast matching conditions in deuterated water, allowed precise differentiation between free and nanoparticle-bound proteins, demonstrating that PC molecule exchange occurred homogeneously within 4 h of scattering measurements and remains stable for at least 12 h. These findings provide insights into molecule behavior within PC, with implications for nanoparticle design in biomedical applications. © 2025 American Chemical Society.

    Alkali metal alkoxyborate ester salts; a contemporary look at old compounds
    (Royal Society of Chemistry (RSC), 2024-01-25) Berger, A; Ibrahim, A; Hales, TA; D'Angelo, AM; Buckley, CE; Paskevicius, M
    Research into the use of sodium tetraalkoxyborate salts for different chemical applications including synthetic catalysis, hydrogen storage, or battery applications has been investigated, however, understanding of the structural, thermal and electrochemical properties of these salts has been lacking since the 1950s and 1960s. A review of the synthesis, as well as a thorough characterization using 1H NMR, 11B NMR, 13C{1H} NMR, FTIR, XRD, in situ XRD, DSC-TGA, RGA-MS, TPPA, and EIS has newly identified polymorphic phase changes for Na[B(OMe)4], K[B(OMe)4], Li[B(OMe)4], Na[B(OEt)4], Na[B(OBu)4], and Na[B(OiBu)4]. The crystal structure of K[B(OMe)4] was also solved in I41/a (a = 22.337(2) Å, c = 7.648(3) Å, V = 3815.6(4) Å3, ρ = 1.128(1) g cm−3). Ionic conductivity of the different salts was analyzed, however it was found that the compounds with longer alkyl chains had no measurable ionic conductivity compared to the shorter chained samples, Na[B(OMe)4] and K[B(OMe)4] with 9.6 × 10−8 S cm−1 and 1.6 × 10−7 S cm−1, at 114 °C respectively. © 2024 The Author(s).

    An exceptional assemblage of archaeological plant fibres from Windmill Way, southeast Cape York Peninsula
    (Taylor & Francis, 2025-11-14) Wallis, LA; Burke, H; Musgrave, C; George, R; Coleman, NV; Marsh, S; Callaghan, C; Dardengo, M; Cole, N; Hiscock, W; Jacobsen, GE; Hadnutt, N; Snep, A; Matheson, C
    To date only a handful of Australian archaeological sites with plant-based objects from the Mid-to-Late Holocene are known. This paper substantially increases this dataset by describing an assemblage of more than 500 fibre fragments from the site of Windmill Way in southeast Cape York Peninsula, Queensland. These objects predominantly represent the end stages of fibre processing, primarily comprising string and netted and looped fabric, with an age range spanning from 1,700–1,589 cal BP to 252–75 cal BP. While the highly fragmented nature of the Windmill Way assemblage makes definitive identification of individual objects difficult, double looping, rather than knotting, was the preferred means of construction, with many pieces clearly deriving from dillybags. Rarer pieces may be fragments of pubic tassel belts or mourning strings. The string, knots, mesh, gauge and loops were all relatively uniform through time, demonstrating intergenerational knowledge of a refined and stable practice. The presence of only two post-contact items (a hooked piece of wire and a strip of red cloth), combined with the radiocarbon sequence, suggests that the site was abandoned around the time Europeans invaded the region in 1874, when wide-scale frontier conflict commenced. Detailed microscopic analysis of the fibres to identify plant species, as well as analyses of the macrobotanics, resins and other organic material culture items recovered from the site are ongoing. © 2025 The Author(s).
