ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 7.5. 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.

Equilibration kinetics of undoped BaTio3 within the n-p transition regime
(Australasian Ceramic Society, 1998) Nowotny, J; Rekas, M
Electrical conductivity was applied to monitor the equilibration kinetics for undoped BaTiO3 single crystal within the n-p-type transition regime during both oxidation and reduction experiments. The equilibration curves exhibit minima corresponding to the n-p transition point. Chemical diffusion coefficient in BaTiO3 was determined in the range 800-1100 K.

Equilibration kinetics of undoped BaTio3
(Australasian Ceramic Society, 1998) Nowotny, J; Rekas, M
Electrical conductivity was applied to monitor isothermal equilibration kinetics for undoped BaTiO3 single crystal within p-type regime at 1205 K during an oxidation experiment. Chemical diffusion coefficient in BaTiO3 was determined using two different analytical solutions of the Flick's second law involving a parabolic equation and a logarithmic equation. A very good agreement between the diffusion coefficients obtained using these equations (1.249x10-5 and 1.29x10-5 cm2s-1, respectively) was revealed.

Surface dynamics of zirconia at room temperature
(Australasian Ceramic Society, 1998) Bak, T; Li, X; Nowotny, J; Sorrell, CC; Zhang, ZM
The work function of yttria-doped (10 mol%) zirconia was measured at room temperature as a function of time during oxidation and reduction. It was observed that the character of the work function changes depends on the applied surface preparation procedure. It was observed that doping the surface with Ca results in a complex mechanism of oxygen reactivity with the zirconia surface involving initial oxygen-induced reconstruction of the overlayer structure and subsequent chemisorption and incorporation of oxygen into the lattice.

Uranyl oxide hydrate phases with heavy lanthanide ions: [Ln(UO2)2O3(OH)]·0.5H2O (Ln = Tb, Dy, Ho and Yb)
(Royal Society of Chemistry, 2018-05-16) Zhang, YJ; Aughterson, RD; Karatchevtseva, I; Kong, LG; Tran, TT; Čejka, J; Aharonovich, I; Lumpkin, GR
Four uranyl oxide hydrate phases with heavy lanthanide ions, [Ln(UO2)2O3(OH)]·0.5H2O [Ln = Tb (1), Dy (2), Ho (3) and Yb (4)], have been synthesized under hydrothermal conditions at 240 °C and characterized. SEM-EDS revealed that these phases have very similar thin plate morphologies with a U to Ln atomic ratio of 2 : 1, which is further confirmed by TEM-EDS. Their high magnification TEM bright field images showed small crystalline domains (∼2–5 nm) with preferred crystal orientations. Both XRD and TEM SAED confirmed that they crystallize in the trigonal crystal system with the P[3 with combining macron]m1 space group. Raman characterization revealed the typical vibration modes for the uranyl units with the calculated U[double bond, length as m-dash]O bond lengths are comparable to the values reported for other UOH phases with d-transition metal ions as the interlayer species. The possible presence of a pentavalent uranyl unit has been ruled out by UV-vis-NIR spectroscopy. The thermal and optical properties have also been investigated and reported. © Royal Society of Chemistry 2025.

Design and performance of the variable-wavelength Bonse–Hart ultra-small-angle neutron scattering diffractometer KOOKABURRA at ANSTO
(International Union of Crystallography, 2018-02-01) Rehm, C; de Campo, L; Brûlé, A; Darmann, FA; Bartsch, FJK; Berry, A
The double-crystal ultra-small-angle neutron scattering (USANS) diffractometer KOOKABURRA at ANSTO was made available for user experiments in 2014. KOOKABURRA allows the characterization of microstructures covering length scales in the range of 0.1–10 µm. Use of the first- and second-order reflections coming off a doubly curved highly oriented mosaic pyrolytic graphite premonochromator at a fixed Bragg angle, in conjunction with two interchangeable pairs of Si(111) and Si(311) quintuple-reflection channel-cut crystals, permits operation of the instrument at two individual wavelengths, 4.74 and 2.37 Å. This unique feature among reactor-based USANS instruments allows optimal accommodation of a broad range of samples, both weakly and strongly scattering, in one sample setup. The versatility and capabilities of KOOKABURRA have already resulted in a number of research papers, clearly demonstrating that this instrument has a major impact in the field of large-scale structure determination. © International Union of Crystallography.
