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.

    An experimental determination of the thermophysical properties of [NZP]-structure type ceramics
    (Materials Research Society, 2012) Gregg, DJ; Karatchevtseva, I; Triani, G; Lumpkin, GR; Vance, ER
    Calcium and barium zirconium phosphates were prepared by hot isostatic pressing and their thermophysical properties investigated for potential use as actinide hosts for inert matrix fuels (IMF) in light water reactors. The materials are thermally stable up to at least 1600°C in air, however they degrade above around 1400°C in an inert atmosphere. The heat capacity and thermal conductivity were measured from room temperature up to 1200°C. The thermal conductivity coefficient for both CZP and BZP at 1000°C is 1.0 W m-1 K-1, a relatively low thermal conductivity that requires NZP-type materials to be dispersed in a composite cercer or cermet IMF. © Materials Research Society

    222Rn observations for climate and air quality studies
    (International Atomic Energy Agency, 2012) Zahorowski, W; Chambers, SD; Crawford, J; Williams, AG; Cohen, DD; Vermeulen, AT; Verheggen, B
    This paper identifies the current major applications for 222Rn in atmospheric research. Two of these applications, air mass transport and vertical mixing in the lower atmosphere, are illustrated by four separate case studies: (1) Using 222Rn to identify the geographical extent, strength and seasonal variability of land and oceanic emissions; (2) Using 222Rn in pollution studies to improve the performance of clustering algorithms used to define source regions; (3) Using near-surface hourly 222Rn gradient observations from towers as tall as 200 m to investigate diurnal dilution effects in the boundary layer with changing atmospheric stability; and (4) Using vertical 222Rn profile 'snapshots' measured from light aircraft up to 4 km above ground level to contrast boundary layer entrainment rates between clear-sky, convective and stratiform cloud cases. Lastly, a recent set of 222Rn and 222Rn progeny observations is used to discuss the 222Rn/progeny equilibrium factor and illustrate some common problems associated with using 222Rn progeny as a proxy for 222Rn.

    The fate of organic species upon sintering of thiol-stabilised gold nanoparticles under different atmospheric conditions
    (Royal Society of Chemistry, 2023-02-20) Summers, PK; Angeloski, A; Wuhrer, R; Cortie, MB; McDonagh, AM
    Understanding and controlling the sintering behavior of gold nanoparticles is important for applications such as printed electronics, catalysis and sensing that utilise these materials. Here we examine the processes by which thiol-protected gold nanoparticles thermally sinter under a variety of atmospheres. We find that upon sintering, the surface-bound thiyl ligands exclusively form the corresponding disulfide species when released from the gold surface. Experiments conducted using air, hydrogen, nitrogen, or argon atmospheres revealed no significant differences between the temperatures of the sintering event nor on the composition of released organic species. When conducted under high vacuum, the sintering event occurred at lower temperatures compared to ambient pressures in cases where the resulting disulfide had relatively high volatility (dibutyl disulfide). Hexadecylthiol-stabilized particles exhibited no significant differences in the temperatures of the sintering event under ambient pressures compared to high vacuum conditions. We attribute this to the relatively low volatility of the resultant dihexadecyl disulfide product. Royal Society of Chemistry 2025.

    Nanostripes in superconducting REBa2Cu3O7-δ superconductors: robust vortex pinning sites
    (SPIE, 2006-01-03) Hu, A; Zhou, H; Bell, JM; Evans, PJ
    We report a naturally grown stripe structure with a nanometer scale wavelength in REBa2Cu3O7-δ (RE = Sm and Eu) superconductors investigated with scanning tunneling microscopy (STM) and transmission electron microscopy (TEM). Such a periodic array was unveiled owning to the 3 dimensionally spatial oscillation of RE and Ba around the stoichiometric ratio. The study displayed that novel nanostripes function as robust pinning sites and effectively enhance the peak effect and the irreversibility line at 77K. This illustrates an approach to fabricate high performance REBa2Cu3O7-δ superconductors for application in liquid nitrogen temperature. © (2006) Society of Photo-Optical Instrumentation Engineers (SPIE).

    Modelling creep of pressure vessels with thermal gradients using Theta projection data
    (Elsevier, 2002-12) Law, M; Payten, WM; Snowden, KJ
    Pressure vessels are often exposed to through-wall temperature gradients. Thermal stresses occur in addition to pressure stresses. The resulting creep response is calculated using the Theta projection creep algorithm within a finite element code. It was found that the stress and temperature dependence of the creep response may lead to complex stress evolution. © 2002 Elsevier Science Ltd.
