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.

    Investigation of mechanical property changes in He2+ ion irradiated MA957 through nanoindentation and in situ micro-tensile testing
    (Elsevier, 2021-04-15) Xu, A; Susanto, I; Wei, T; Ionescu, M; Daniels, JE; Bhattacharyya, D
    A sample of oxide dispersion strengthened (ODS) MA957 steel was irradiated with 5 MeV He2+ ions in the STAR accelerator and its mechanical property changes were tested by nanoindentation and also in tension using an in situ micro-mechanical testing device inside a scanning electron microscope. The ion irradiation process was accomplished using an Al degrader wheel to obtain a relatively uniform damage profile compared to single energy irradiation, with an average dose of ~1.5 displacements per atom (dpa) up to a depth of ~ 10 μm. The small grain size (0.25 – 1.7 μm) of the material enabled the micro-tensile samples (~ 5 × 5 × 17 μm) to be treated essentially as polycrystalline specimens. The results of the tensile tests before and after the radiation are analysed with the aid of strain measurement through a digital correlation method. These results are then compared with nanoindentation hardness measurements. Transmission electron microscopy images reveal a high density of fine (1 nm diameter) bubbles, along with a relatively low density of dislocation loops. An estimation of strengthening due to these sources using the dispersed barrier hardness model shows that a root sum square superposition law predicts the increase in strength to a good degree of accuracy. It is apparent that a major fraction of the increase in strength due to ion irradiation could be attributed to He bubbles, and only a relatively small proportion of the hardening to dislocation loops and black dot damage. © 2021 Published by Elsevier B.V.

    A possible magnetic structure of the cluster-based Haldane compound fedotovite K2Cu3O(SO4)3
    (Physical Society of Japan, 2019-08-19) Hase, M; Rule, KC; Hester, JR; Fernandez-Baca, JA; Masuda, T; Matsuo, Y
    We carried out neutron powder diffraction experiments on the cluster-based Haldane compound fedotovite K2Cu3O-(SO4)3. Weak magnetic reflections caused by a magnetic long-range order appeared below an antiferromagnetic transition temperature TN = 3.1 K. We propose a possible magnetic structure that is consistent with the magnetic properties reported in the literature. ©2019 The Physical Society of Japan.

    Synthesis and optical properties of crystalline Si1-xGexOy nanorods
    (World Scientific Publishing, 2013-12) Zhou, CW; Cai, KF; Yu, DH; Du, Y
    Crystalline Si 1-x Ge x O y nanorods were successfully synthesized by a chemical vapor deposition method using germanium as a starting material on Au -coated Si (111) substrate at ~ 1000°C in a flowing high-purity Ar atmosphere. Most of the nanorods have smooth surfaces, with diameters ranging from ~ 50 nm to 165 nm and lengths longer than several microns. Ultraviolet-visible absorption spectrum of the nanorods shows a maximum absorption wavelength at 203 nm. Photoluminescence spectrum of the nanorods exhibits an ultraviolet emission peak at 336 nm. The growth of the nanorods follows a vapor–liquid–solid mechanism.

    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.
