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.

    THz filters made by laser ablation of stainless steel and kapton film
    (MDPI, 2022-07-25) Han, ML; Smith, D; Ng, SH; Vilagosh, Z; Anand, V; Katkus, T; Reklaitis, I; Mu, H; Ryu, M; Morikawa, J; Vongsvivut, JP; Appadoo, DRT; Juodkazis, S
    THz band-pass filters were fabricated by femtosecond-laser ablation of 25-μm-thick micro-foils of stainless steel and Kapton film, which were subsequently metal coated with a ∼70 nm film, closely matching the skin depth at the used THz spectral window. Their spectral performance was tested in transmission and reflection modes at the Australian Synchrotron’s THz beamline. A 25-μm-thick Kapton film performed as a Fabry–Pérot etalon with a free spectral range (FSR) of 119 cm−1, high finesse Fc≈17, and was tuneable over ∼10μm (at ∼5 THz band) with β=30∘ tilt. The structure of the THz beam focal region as extracted by the first mirror (slit) showed a complex dependence of polarisation, wavelength and position across the beam. This is important for polarisation-sensitive measurements (in both transmission and reflection) and requires normalisation at each orientation of linear polarisation. © 2022 by the authors.

    Constructing LiMn6 superlattice covalent framework to enable reversible anionic redox toward layer‐structured oxide for sodium batteries
    (Wiley, 2025-12-16) Lai, QS; Yue, H; Yang, DR; Gao, GP; Chen, H; Gao, XW; Liu, ZM; Gu, QF; Luo, WB
    High-voltage anionic redox reactions offer an effective approach to enhancing the energy density for layer-structured oxides. However, such reactions are often accompanied by complex structural rearrangements and oxygen release, posing significant challenges to structural stability. A superstructure-regulating strategy is employed to construct LiMn6 ribbon ordering in O3-type Na[Li0.1Ni0.2Mn0.6Cu0.05Ti0.05]O2, aiming to address these issues and achieve high energy density alongside long-term cycling performance. Combined theoretical and experimental investigations it reveals that the incorporation of Li enhances electron localization around neighboring oxygen atoms, thereby modulating anionic redox activity. Moreover, the ordered LiMn6 framework facilitates directional hybridization between Mn 3d eg, and O 2p orbitals, forming a highly covalent network that effectively suppresses P-to-O type phase transitions and transition metal migration, thereby enhancing structural stability under high-voltage operation. The modified material delivers a highly reversible capacity of 207.98 mAh g−1 and exhibits excellent capacity retention of 80.43% after 125 cycles within a wide voltage range of 1.5–4.5 V. Furthermore, a full cell assembled with hard carbon as the anode demonstrates a capacity retention of 76.6% after 300 cycles. This work provides a new perspective on the superstructural design of high-performance O3-type cathodes for advanced sodium-ion batteries.

    Lanthanoid heteroleptic complexes with cucurbit[5]uril and dicarboxylate ligands: from discrete structures to one-dimensional and two-dimensional polymers
    (American Chemical Society (ACS), 2019-01-07) Zhang, YJ; Panjikar, S; Chen, K; Karatchevtseva, I; Tao, Z; Wei, G
    Lanthanoid heteroleptic complexes with cucurbit[5]uril {Q[5]} and two dicarboxylate ligands, e.g., diglycolic acid (H2DGC) and glutaric acid (H2GT), have been investigated with six new compounds featuring a tetrametallic and dimetallic discrete structures, a one-dimensional (1D) polymer, and three two-dimensional (2D) polymers with a unique honeycomb-type topology being synthesized and structurally characterized. [La4(Q[5])3(DGC)2(NO3)2(H2O)12][La(DGC)(H2O)6]·7NO3·nH2O (1) has a tetrametallic structure constructed with three bis-bidentate Q[5] ligands linking two [La(DGC)(H2O)2]+ species in the middle and two [La(H2O)4(NO3)]2+ species at both ends. [Ce2(Q[5])(DGC)(NO3)(H2O)10]·3NO3·4H2O (2) has a dimetallic structure built up with a bis-bidentate Q[5] ligand linking [Ce(DGC)(H2O)3(NO3)] and [Ce(H2O)7]3+ on each side of the Q[5] portals. [Ce3(Q[5])3(DGC)2(H2O)9][Ce(DGC)(H2O)6]2·7NO3·nH2O (3) has a 1D polymeric structure built up with bis-bidentate Q[5] ligands in-turn linking one [Ce(H2O)6]3+ and two [Ce(DGC)(H2O)6]1+ cationic species. [Ln2(Q[5])2(GT)(H2O)6]·4NO3·nH2O [Ln = La (4), Ce (5) and Nd (6)] have similar 2D polymeric structures built up with two types of 9-fold coordinated Ln polyhedra linked by Q[5] via bis-bidentate carbonyl groups on both sides forming 1D chains which are further connected by bridging GT2– ligands to form 2D polymers with a unique honeycomb-type topology. Their vibrational modes and electronic structures have also been investigated. © 2018 American Chemical Society.

    Four-polarisation camera for anisotropy mapping at three orientations: micro-grain of olivine
    (MDPI, 2023-09-18) Kamegaki, SJ; Smith, D; Ryu, M; Ng, SH; Huang, HH; Maasoumi, P; Vongsvivut, JP; Moraru, D; Katkus, T; Juodkazis, S; Morikawa, J
    A four-polarisation camera was used to map the absorbance of olivine micro-grains before and after high-temperature annealing (HTA). It is shown that HTA of olivine xenoliths at above 1200°C in O2 flow makes them magnetised. Different modes of operation of the polariscope with polarisation control before and after the sample in transmission and reflection modes were used. The reflection type was assembled for non-transparent samples of olivine after HTA. The sample for optical observation in transmission was placed on an achromatic, plastic, quarter-wavelength waveplate as a sample holder. Inspection of the sample’s birefringence (retardance), as well as absorbance, was undertaken. The best fit for the transmitted intensity or transmittance T (hence, absorbance A=−log10T) is obtainable using a simple best fit with only three orientations (from the four orientations measured by the camera). When the intensity of transmitted light at one of the orientations is very low due to a cross-polarised condition (polariser–analyser arrangement), the three-point fit can be used. The three-point fit in transmission and reflection modes was validated for T(θ)=Amp×cos(2θ−2θshift)+offset, where the amplitude Amp, offset offset, and orientation azimuth θshift were extracted for each pixel via the best fit. © 2023 by the authors.

    Microstructure and mechanical properties of bulked-wall Inconel 625 through wire and arc-based additive manufacturing
    (Springer Nature, 2025-03-05) Zhang, CX; Qiu, ZJ; Zhu, HL; Wang, ZY; Pan, ZX; Xi, JT; Li, HJ
    In this study, Ni-based Inconel 625 bulk structures with several beads in each layer were manufactured by cold metal transfer based-wire arc additive manufacturing (WAAM) with different heat inputs and active interpass cooling. The macro- and micro-structures, and mechanical properties of the fabricated components were analyzed, especially bulk texture and micro texture were explored in detail. Distinctive from the often-observed strong (200) crystallographic texture in additively manufactured Ni-based alloys, a relatively weak bulk texture was achieved in the produced materials based on neutron diffraction measurements. Consistent with the bulk texture, a random micro-texture was found using the microscopical technique. The dendrite arm spacing of the sample with the lowest heat input was slightly decreased, and precipitates appeared to be lessened, together with refined texture, higher geometrically necessary dislocation density and more low-angle grain boundaries. All these factors promoted enhanced mechanical properties of the lowest heat-input sample (more than 10% higher), compared with other heat-input ones. Some void defects were observed at the bead overlapping areas at layer boundaries, and this is considered due to lack of fusion, and refined surface finish induced by lower heat input contributes to fewer voids. In addition, bulk walls are compared with single-bead walls, and bulk ones possessed about 100 MPa (horizontal) higher tensile strength but more obvious anisotropy than single-bead structures. This work provides insightful knowledge on the micro and macro texture, as well as other microstructural evolution and mechanical properties under various heat inputs in the WAAM of Inconel 625 Ni-based alloy, which contributes to the fabrication of large-sized components by WAAM with high effectiveness.
