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 investigation of sol gel coated zirconia thin films on anodised titanium substrate by secondary ion mass spectrometry and scanning electron microscopy
    (Materials Australia, 2007-07-04) Roest, R; Atanacio, AJ; Latella, BA; Wuhrer, R; Ben-Nissan, B
    Zirconia sol-gel-derived ceramic coatings have a variety of uses, due to their ease of production and ability to coat complex shapes. The sol-gel's nanocrystalline grain structure results in improved mechanical properties of the zirconia coating, which further aids their use in a variety of applications from thermal barrier coating to improved tribological properties on titanium substrates. Stabilised zirconia thin films were spin coated on anodised titanium substrates. The titanium was anodised in a dilute H3P04/H2S04 solution before spin coating with the zirconia sol gel. These films were then studied using secondary ion mass spectrometry (SIMS), to depth profile the elemental species through to the titanium substrate. In conjunction, scanning electron microscopy (SEM) and X - Ray mapping were used to examine the craters formed by SIMS to gain an understanding of the diffusion gradient existing with the anodised titanium substrate and zirconia thin film. This paper is to present the research results of the interface between the zirconia thin film and the anodised titanium substrate

    Effect of evacuation parameters on hot isostatically pressed samples titanate wasteform
    (Materials Australia, 2007-07-04) Eddowes, T; Moricca, SA; Webb, N
    One of the methods for consolidation of titanate ceramic wasteforms (synroc) is that of Hot Isostatic Pressing (HIPing). This involves the powdered wasteform sealed in a metallic canister and heated to appropriate temperatures and pressures. If there are residual volatile gases being evolved during the HIPing process an internal pressure build up can result in residual porosity of the product within. A typical process for encapsulating wasteforms is to heat up the sample in the metal canister (bake out) to remove excess gas and moisture and seal under vacuum to prevent the previously mentioned failure. This study evaluates the effect of the vacuum level required before sealing the metal canister as well as the influence of additives into the wasteform on this level. It has previously been shown that an addition of 2wt % Ti added as a redox buffer to Synroc-C results in a dense durable wasteform when subjected to the standard bake out process. It was found in this study that on a small scale no can breach occurred when the powder comes directly from the calcination process and the can was sealed without pulling a vacuum. However the wasteform composition and its performance were affected by the reaction with excess oxygen sealed in the can. To further replicate a true production environment, these investigations were also carried out on larger scale samples.

    Effect of oxygen activity on Nb solubility in BaTi03
    (Australasian Ceramic Society, 1998) Dupre, B; Kowalski, K; Ijjaalli, M; Nowotny, J
    The procedure of doping of polycrystalline BaTiO3 specimen with Nb is described. It was found that the concentration profile of Nb within the BaTiO3 specimen depends substantially on oxygen activity during annealing. The observed effect is discussed in terms of defect disorder of BaTiO3.

    The National Medical Cyclotron - an Australian experience in technology
    (Australian Nuclear Association, 1997-10-16) Barnes, RK
    The establishment of the National Medical Cyclotron (NMC) in the early 1990's was the practical outcome of a vision, held by nuclear medicine professionals, to complement the available neutron-rich radionuclides produced in Australia, with neutron-deficient radionuclides. The NMC is operated by the Australian Nuclear Science and Technology Organisation (ANSTO) in collaboration with the Royal Prince Alfred Hospital (RPAH) in Sydney where the PET department is able to use the short-lived radiotracers to good advantage. Neutron-deficient radionuclides, are also produced by the NMC laboratories. The cyclotron-generated radionuclides are used in over 70,000 patient studies per year.

    Photoluminescence spectroscopy of BN nanotubes using Synchrotron VUV radiation
    (Materials Australia, 2007-07-04) Yu, J; Chen, Y; Li, LH; Yu, DH; Stampfl APJ; Cheng, BM
    We report the photoluminescence spectroscopy (PL) of BN nanotubes using synchrotron VIJV radiation. The nanotubes with different sizes and structures were produced using the ball milling and annealing method, in which amorphous boron was first milled in ammonia gas at 300 KPa for 150 hours with steel rolling mill, followed by a thermal annealing in nitrogen or ammonia gas. The emission spectra of BN nanotubes after VIJV excitation show that photoluminescence of BN nanotubes depends on nanotube sizes and structures, as well as temperatures. The PL spectra of thin cylindrical BN nanotubes (diameter less than 10 nm) are significantly different from that of thick nanotubes (diameter around 100 nm). This may be due to the band gap changes from quantum confinement effect. The photoluminescence of BN nanotubes, especially for thin cylindrical nanotubes also depends on temperature of the samples.
