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.

    Quantum dot and silica nanoparticle doped polymer optical fibers.
    (Optica Publishing Group, 2007) Yu, HCY; Argyros, A; Barton, G; van Eijkelenborg, MA; Barbe, CJ; Finnie, KS; Kong, LG; Ladouceur, F; McNiven, S
    A novel and highly versatile doping method has been developed to allow active dopants, including materials incompatible with the polymer matrix, to be incorporated into microstructured polymer optical fibers through the use of nanoparticles. The incorporation of quantum dots and silica nanoparticles containing Rhodamine isothiocyanate is demonstrated. ©2007 Optical Society of America.

    Bonding of histidine to cerium oxide
    (American Chemical Society (ACS), 2013-07-02) Tsud, N; Acres, RG; Iakhnenko, M; Mazur, D; Prince, KC; Matolín, V
    Adsorption of histidine on cerium oxide model surfaces was investigated by synchrotron radiation photoemission, resonant photoemission, and near edge X-ray absorption fine structure spectroscopies. Histidine was evaporated in a vacuum onto ordered stoichiometric CeO2(111) and partially reduced CeO 1.9 thin films grown on Cu(111). Histidine binds to CeO2 in anionic form via the carboxylate group and all three nitrogen atoms, with the imidazole ring parallel to the surface. The amino nitrogen atom of the imidazole ring (IM) is deprotonated, and both IM nitrogen atoms form strong bonds via π orbitals, while the α-amino nitrogen interacts with the oxide via its hydrogen atoms. In the case of CeO1.9, the deprotonation of the amino nitrogen of the imidazole ring is less pronounced and N K-edge spectra do not show a clear orientation of the ring with respect to the surface. A minor reduction of the cerium surface on adsorption of histidine was observed and explained by charge exchange as a result of hybridization of the π orbitals of the IM ring with the f and d orbitals of ceria. Knowledge of histidine adsorption on the cerium oxide surface can be used for design of mediator-less biosensors where the histidine-containing proteins can be strongly bound to the oxide surface via the imidazole side chain of this residue. © 2013 American Chemical Society.

    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)).
