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.

    A technique to achieve estimation of the amount of absorbed energy when using diverse cell types at THz frequencies
    (Institute of Electrical and Electronics Engineers, 2022-12-12) Vilagosh, Z; Appadoo, DRT; Perera, PGT; Nguyen, THP; Linklater, D; Juodkazis, S; Croft, R; Ivanova, EP
    The effects of a high frequency electromagnetic field (HF EMF) in the terahertz (THz) range on biological systems is the subject of ongoing investigation. With a beamline range of 0.5 THz - 20 THz, the THz/Far-IR beamline at the Australian Synchrotron is ideally suited to explore possible THz effects. We have developed a technique to achieve precise estimation of the amount of absorbed energy when using diverse cell types at THz frequencies. The approach involves evaluating the overall incident beam power, the determination of the frequency and photon dispersion, and evaluating the relative contribution of the frequency ranges. The sample depth is an important component of the evaluation. Since higher THz frequencies have shallower sample penetration depths, parts of the sample are being exposed to not only different total THz energy doses, but to a different frequency profile. Our technique achieves accurate estimation of the exposure profile. © Copyright 2026 IEEE

    The magneto-structural transition in Mn1−xFexCoGe
    (IOP Publishing, 2016-05-29) Ren, QY; Hutchison, WD; Wang, JL; Studer, AJ; Din, MFM; Pérez, SM; Cadogan, JM; Campbell, SJ
    Large refrigeration capacities, between 212(30) J kg-1 and 261(40) J kg-1 for a magnetic field change from 0 T to 5 T, were obtained in Mn1-xFexCoGe (x = 0.01, 0.02, 0.03 and 0.04) compounds. A partial magnetic phase diagram has been derived on the basis of magnetic transition and martensitic transformation temperatures determined from differential scanning calorimetry (200 K to 450 K), variable temperature x-ray diffraction (20 K to 310 K) and magnetisation measurements (5 K to 340 K; 0.01 T). Mn1-xFexCoGe compounds with compositions in the range x = 0.01 to 0.03 exhibit magneto-structural transitions. Neutron diffraction experiments were carried out on the Mn0.98Fe0.02CoGe sample over the temperature range of 5 K to 450 K. The diffraction patterns were analysed based on irreducible representation theory which confirms a ferromagnetic structure in the sample with an atomic magnetic moment of 3.7(1)μB at 5 K on the Mn sublattice, oriented along the orthorhombic c axis. More significantly, a magneto-structural transition around TM ∼ 297(1) K with a full width at half maximum of 29 K is demonstrated directly via neutron diffraction. Larger magnetic entropy changes are obtained for the Mn1-xFexCoGe (x = 0.01, 0.02 and 0.03) samples than for Mn0.96Fe0.04CoGe which has separate structural and magnetic transitions. In addition, it is noted that standard Arrott plots do not provide unambiguous insight to the nature of the magneto-structural transition in the Mn1-xFexCoGe compounds. © 2016 IOP Publishing Ltd© 2016 IOP Publishing Ltd.

    Petrophysical characterization at the extremes and across three continents: contrasting examples from Utica, Marcellus, Longmaxi and Roseneath-Murteree resource shales
    (Unconventional Resources Technology Conference, 2017-01-01) Clennell, MB; Josh, M; Esteban, L; Piane, CD; Dewhurst, D; Luzin, V
    We investigated geological, petrophysical, rock physics and engineering properties of resource shales using well data and core samples from three continents. The North American Utica-Point Pleasant example, spanning carbonates, marls and shales, came from the base of the oil window in this play. Extremely high resistivity invalidated the Passey method for total organic carbon (TOC) calculation, while elevated uranium marked the original source beds rather than the maximum of organic matter found in underlying carbonates where pyrobitumen is abundant. A 1 GHz dielectric log enabled us to develop a new crossplot where matrix, water and organic matter effects could be differentiated. The North American Marcellus shale example represented the other extreme of thermal maturity, where vitrinite reflectance exceeds 4 % Ro and the organic matter is partly transformed to highly conductive proto-graphite, again complicating petrophysical interpretations. The Chinese Longmaxi shale has classical �hot shale� characteristics where U content from logs or core scanning gives a good estimate of TOC. In both cases, siliceous matrix may be advantageous in terms of rock brittleness but may lock up gas in inaccessible pores. The Roseneath and Murteree Shales of the Australian Cooper Basin represent a hybrid shale/tight gas resource play where Gas in Place (GIP) is dominated by free gas, largely sourced from nearby coals, in inter-mineral pore space. Dielectric responses of lab samples show a linear relationship between water content and permittivity, however no downhole dielectric logs are yet available to evaluate this approach to identify sweet spots. Aside from using advanced petrophysical and microstructural methods we gained insights from standard log correlations. We found that neutron porosity alone could entirely predict the organic-free (background) resistivity log response in the Murteree shale via the non-linear equation: 1/_ = ? * ?^. We propose that hydrated cation conductivity determines the pre-factor C, while pore geometry/topology determine the value of exponent d. The application of such nonlinear relationships to modern machine learning methods warrants further investigation. © 2017. Unconventional Resources Technology Conference

    Nano-structured antibiofilm coatings based on recombinant resilin
    (Elsevier, 2025-08) Wanasingha, N; Balu, R; Gangadoo, S; Abraham, AN; Rekas, A; Mata, JP; Le Brun, AP; Dutta, NK; Choudhury, NR
    The applications of responsive biomaterials for tuning cell-surface interactions have been recently explored due to their unique switchable characteristics. However, rational design of surfaces using suitable biomacromolecules to attain optimal physicochemical performance, biocompatibility, cell adhesion and anti-fouling properties is quite challenging. Resilin-mimetic polypeptides (RMPs) are intrinsically disordered biomacromolecules that exhibit multi-stimuli responsive behaviour, including reversible dual-phase thermal behaviour forming self-assembled nano- to microstructures. However, there is a limited understanding of the effect of morphological features of RMP-based nanostructures, and their influence on surface properties. Therefore, in this study, a family of responsive RMP-based nanostructured coatings (nano-coacervates, nanogels and nano-bioconjugates) are fabricated to investigate their various surface properties that influence cell-surface interactions. The effects of their physicochemical properties, such as conformation, packing density, charge, roughness, and stiffness, are investigated using atomic force microscopy, neutron scattering and reflectometry techniques. Biocompatibility and microbiological testing show that these nanostructured switchable responsive coatings can be applied to a wide range of substrates to modulate biofilm formation and attribute antimicrobial characteristics. The developed nanocoatings have the potential to find applications in many areas, including implantable medical devices, and drug delivery. © 2025 Elsevier B.V.

    Synthesis of ammine dual-metal (V, Mg) borohydrides with enhanced dehydrogenation properties
    (Elsevier, 2013-05) Yuan, F; Chen, XW; Gu, QF; Tang, ZW; Yu, XB
    The penta-ammine vanadium (III) borohydride, i.e. V(BH4) 3·5NH3, was successfully synthesized via ball-milling of VCl3·5NH3 and LiBH4 in a molar ratio of 1:3. This compound was shown to release 11.5 wt% hydrogen with a H2-purity of 85 mol% by 350 °C. To improve the dehydrogenation purity of V(BH4)3·5NH3, Mg(BH 4)2 with various molar ratios was mixed with V(BH 4)3·5NH3 to synthesize expected ammine metal-mixed borohydrides, among which the formed VMg(BH4) 5·5NH3 was indexed to be a monoclinic unit cell with lattice parameters of a = 19.611 Å, b = 14.468 Å, c = 6.261 Å, β = 93.678° and V = 1772.75 Å3. Dehydrogenation results revealed that the Mg(BH4)2 modified V(BH4)3·5NH3 system presents significantly enhanced dehydrogenation purity. For example, in the case of V(BH4)3·5NH3/2Mg(BH4) 2 sample, 12.4 wt% pure hydrogen can be released upon heating to 300 °C. Further investigation on the dehydrogenation mechanism of the VMg(BH4)5·5NH3 system by isotope tagging revealed that the interactions of homo-polar BH units also participated throughout the dehydrogenation process (onset at 75 °C) as complementary to the prime combination of BH···HN.
