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.

    Activity measurements of the radionuclides 18F, 64Cu and 99mTc for the ANSTO, Australia, in the ongoing comparisons BIPM.RI(II)-K4 series and KCRV update in the corresponding BIPM.RI(II)-K1 comparison
    (IOP, 2023-05-19) Michotte, C; Nonis, M; van Wyngaardt, WM; Tobin, SM; Smith, ML; Lee, S; Jackson, TW; Ilter, J; Howe, B; Sarbutt, A; da Silva I
    In 2017, comparisons of activity measurements of 18F, 64Cu and 99mTc using the Transfer Instrument of the International Reference System (SIRTI) took place at the Australian Nuclear Science and Technology Organisation (ANSTO, Australia). Ampoules containing 18F, 64Cu and 99mTc solutions were measured in the SIRTI for about 1.7 to 4 half-lives. The ANSTO carried out the primary standardization of the activity in the ampoules by 4π(LS)β−γ coincidence measurements. The comparisons, identifiers BIPM.RI(II)-K4.F18, BIPM.RI(II)-K4.Cu-64 and BIPM.RI(II)-K4.Tc-99m are linked to the corresponding BIPM.RI(II)-K1.F-18, BIPM.RI(II)-K1.Cu-64 and BIPM.RI(II)-K1.Tc-99m comparisons. The BIPM.RI(II)-K1 18F and 99mTc key comparison reference values have been updated to include the latest BIPM.RI(II)-K4 linked results and degrees of equivalence for those three comparisons have been evaluated. © 2023 BIPM & IOP Publishing Ltd

    Inorganic nanoparticles/metal organic framework hybrid membrane reactors for efficient photocatalytic conversion of CO2
    (American Chemical Society (ACS), 2017-09-22) Maina, JW; Schütz, JA; Grundy, L; Ligneris, ED; Yi, ZF; Kong, LX; Pozo-Gonzalo, C; Ionescu, M; Dumée, LF
    Photocatalytic conversion of carbon dioxide (CO2) to useful products has potential to address the adverse environmental impact of global warming. However, most photocatalysts used to date exhibit limited catalytic performance, due to poor CO2 adsorption capacity, inability to efficiently generate photoexcited electrons, and/or poor transfer of the photogenerated electrons to CO2 molecules adsorbed on the catalyst surface. The integration of inorganic semiconductor nanoparticles across metal organic framework (MOF) materials has potential to yield new hybrid materials, combining the high CO2 adsorption capacity of MOF and the ability of the semiconductor nanoparticles to generate photoexcited electrons. Herein, controlled encapsulation of TiO2 and Cu-TiO2 nanoparticles within zeolitic imidazolate framework (ZIF-8) membranes was successfully accomplished, using rapid thermal deposition (RTD), and their photocatalytic efficiency toward CO2 conversion was investigated under UV irradiation. Methanol and carbon monoxide (CO) were found to be the only products of the CO2 reduction, with yields strongly dependent upon the content and composition of the dopant semiconductor particles. CuTiO2 nanoparticle doped membranes exhibited the best photocatalytic performance, with 7 μg of the semiconductor nanoparticle enhancing CO yield of the pristine ZIF-8 membrane by 233%, and methanol yield by 70%. This work opens new routes for the fabrication of hybrid membranes containing inorganic nanoparticles and MOFs, with potential application not only in catalysis but also in electrochemical, separation, and sensing applications. © 2017 American Chemical Society.

    Microfluidic radiosynthesis of the muscarinic M2 imaging agent [18F]FP-TZTP*
    (CSIRO Publishing, 2018-08-31) Matesic, L; Greguric, ID; Pascali, G
    3-(4-(3-[18F]Fluoropropylthio)-1,2,5-thiadiazol-3-yl)-1-methyl-1,2,5,6-tetrahydropyridine ([18F]FP-TZTP) is a selective 18F-radiotracer for the muscarinic acetylcholine receptor subtype M2, which can be used to perform positron emission tomography (PET) scans on patients with neurological disorders such as Alzheimer’s disease. [18F]FP-TZTP was produced using continuous-flow microfluidics, a technique that uses reduced amounts of chemical reagents, shorter reaction times and in general, results in higher radiochemical yields compared to currently used techniques. The optimal 18F-radiolabelling conditions consisted of a total flow rate of 40 µL min−1 and 190°C, which produced [18F]FP-TZTP in 26 ± 10 % radiochemical yield with a molar activity of 182 ± 65 GBq µmol−1 and >99 % radiochemical purity. © 2018 The Author(s) (or their employer(s)).

    The effect of inter-granular constraints on the response of polycrystalline piezoelectric ceramics at the surface and in the bulk
    (AIP Publishing, 2016-08-31) Hossain, MJ; Wang, ZY; Khansur, NH; Kimpton, JA; Oddershede, J; Daniels, JE
    The electro-mechanical coupling mechanisms in polycrystalline ferroelectric materials, including a soft PbZrxTi1−xO3 (PZT) and lead-free 0.9375(Bi1/2Na1/2)TiO3-0.0625BaTiO3 (BNT-6.25BT), have been studied using a surface sensitive low-energy (12.4 keV) and bulk sensitive high-energy (73 keV) synchrotron X-ray diffraction with in situ electric fields. The results show that for tetragonal PZT at a maximum electric field of 2.8 kV/mm, the electric-field-induced lattice strain (ε111) is 20% higher at the surface than in the bulk, and non-180° ferroelectric domain texture (as indicated by the intensity ratio I002/I200) is 16% higher at the surface. In the case of BNT-6.25BT, which is pseudo-cubic up to fields of 2 kV/mm, lattice strains, ε111 and ε200, are 15% and 20% higher at the surface, while in the mixed tetragonal and rhombohedral phases at 5 kV/mm, the domain texture indicated by the intensity ratio, I111/I111¯ and I002/I200, are 12% and 10% higher at the surface than in the bulk, respectively. The observed difference in the strain contributions between the surface and bulk is suggested to result from the fact that surface grains are not constrained in three dimensions, and consequently, domain reorientation and lattice expansion in surface grains are promoted. It is suggested that the magnitude of property difference between the surface and bulk is higher for the PZT than for BNT-6.25BT due to the level of anisotropy in the strain mechanism. The comparison of the results from different methods demonstrates that the intergranular constraints have a significant influence on the electric-field-induced electro-mechanical responses in polycrystalline ferroelectrics. These results have implications for the design of higher performance polycrystalline piezoelectrics. © 2016 Author(s).

    Proximate electronic and magnetic phase transitions in CaFe3O5
    (American Physical Society (APS), 2024-12-16) Milton, MJ; Hakala, BV; Hong, KH; Avdeev, M; Ling, CD; Kennedy, BJ; Manuel, P; Attfield, JP
    Electronic phase separation in lightly doped CaFe3⁢O5 has been investigated through a variable temperature powder neutron diffraction study of CaFe2.99⁢𝑀0.01⁢O5 (𝑀=Co, Mn) samples. This reveals a complex series of proximate phase transitions. Lattice strains resulting from the onset of charge order (CO) drive formation of a competing charge averaged (CA) phase that emerges at 𝑇CA=𝑇CO=320 K. The CA phase emerges as magnetically ordered but the long range spin ordering transition is limited by domain growth and so occurs at a slightly lower temperature (𝑇CA⁡(m)=301 K for both samples). Magnetic ordering in the CO phase is not directly coupled to the other transitions, but is nearby in temperature with 𝑇CO⁡(m)=290⁢(1) and 292(1) K for 𝑀=Co and Mn samples. The remarkable coincidence of energy scales for the formation of two distinct electronic ground states with differing lattice strains and their long range spin orders thus results in electronic and magnetic phase separation through a series of thermally proximate phase transitions in lightly doped CaFe3⁢O5. ©2025 American Physical Society.
