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.

PELICAN - a time of flight cold neutron spectrometer - recent scientific outcomes and new capabilities
(Australian Institute of Physics, 2024-02-06) Yu, DH; Mole, RA
The time-of-flight direct-geometry neutron spectrometer, Pelican, has been in user program since 2014 at the OPAL research reactor, at the Australian Nuclear Science and Technology Organisation (ANSTO). The Pelican instrument was designed to meet the diverse requirements of the Australian scientific community from physics, chemistry, material science, to biology. A wide range of research fields is covered. These include crystal-field excitations, phonon densities of states, magnetic excitations for various multifunctional materials including high Tc superconductors, novel magnetic, thermoelectric, ferroelectric and piezoelectric materials; molecular dynamics in hydrogen-bonded and storage materials, catalytic materials, cements, soils and rocks; and water dynamics in proteins and ion diffusion in membranes. Polarized neutrons and polarisation analysis option makes the full use of the neutron spin to study magnetism and to separate the coherent and incoherent scatterings. In this presentation, the recent scientific outcomes and recent developments of new capabilities of the instrument will be demonstrated with several systems studied using quasi-elastic and inelastic neutron scatterings. These include water dynamics around amino acids, crystal field excitations in magnetic molecular crystals, low energy magnetic excitations in spin frustrated magnet, oxygen diffusion in solid oxide conductors and phonon density of states in energy materials. To meet the demand of diverse user community, new sample environment equipment has been developed and commissioned including high pressure cell, in-situ light irradiation, fast dilution temperature cooling system and superconducting magnet. The upgrade of the instrument with focusing guides and further test of the polarisation system will be highlighted

Taipan: a highly versatile neutron spectrometer for Condensed Matter investigations
(Australian Institute of Physics, 2024-05) Rule, KC; You, M; Lord, K; Portwin, K; Allen. J; Zhao, W
Taipan is the thermal neutron spectrometer located in the reactor beam hall at the Australian Centre for Neutron Scattering. Originally built as a thermal Triple Axis Spectrometer (TAS), it has been part of the ACNS user program since 2010. Taipan has seen a number of major upgrades including the extension of the dance floor (2014), and the implementation of a new Cu-200 monochromator (2017) which allows Taipan to easily reach incident energies of 200meV [1]. Also, in 2017 a new secondary spectrometer, the Be-filter was installed allowing for rapid measurements of density of states of polycrystalline samples [2]. The TAS and Befilter are interchangeable secondary spectrometers which are used at Taipan with a ratio of 75:25% respectively. In this presentation, I would like to detail some recent results collected from Taipan with my students and early career researchers which highlight the versatility of this spectrometer for many different condensed matter investigations. Such results include work on low dimensional magnetic materials, magnetic thin films, thermoelectric materials, and magnetic coupling in amorphous materials. I would also like to present some recent Be-filter results on alanine, comparing these results to other spectroscopic measurements using alternate techniques.

Nuclear wast storage materials
(Pergamon Press plc, 1991) Reeve, KD
This chapter describes different aspects of nuclear waste storage materials. The operation of a nuclear power reactor producing 1300 MW of electrical power typically results in the accumulation of around 30 t of spent fuel per year. The fuel elements are intact but highly radioactive. Leaching tests on sphene glass ceramics containing simulated waste including some with trace-active doping have confirmed their predicted superiority by at least 1–2 orders of magnitude over borosilicate glass. In the associated radiation-damage assessment program, severe radiation damage produced by argon ion bombardment did not increase the leach rate by more than a factor of five. Other glass ceramics that have been studied as nuclear waste forms are celsian glass ceramics, fresnoite glass ceramics, and basalt glass ceramics. The chapter also briefly discusses the following proposals most of which are at an early stage of development: (1) sintered glass, (2) lead-iron-phosphate glasses, (3) high-silica porous glass matrix, (4) multibarrier concepts, and (5) FUETAP. It further highlights borosilicate glass as a generally accepted first-generation form for high-level nuclear waste solidification and storage. Second-generation waste forms designed to increase public acceptability of nuclear waste disposal in the 21st century should have greatly increased leach resistance in ground water. © 1991 Pergamon Press plc.

In vitro and in vivo studies of boron conjugated melanoma affined biochemicals
(Urban & Vogel GmbH, 1989) Allen, BJ; Brown, JK; Mountford, MH; Tamat, SR; Parwardhan, A; Moore, DE; Ichihashi, M; Mishima, Y; Kahl, SB
The incidence of malignant melanoma (MM) is increasing in caucasians, and in Australia the rate has doubled since the seventies. Queensland has the highest incidence in the world at 33 cases per 100000 people. This increased frequency and poor prognosis for advanced cases has prompted an increased interest in new therapeutic methods. One such method is neutron capture therapy (NCT) which relies on the incorporation of boron compounds in cancer cells. Most of the NCT experiments reported to date have used the B16 murine [3, 4] and HP hamster [2] melanoma cell lines. In order to provide evidence for the wider application of NCT, we have targeted several human MM cell lines with boron conjugated phenylalianine (BPA) [4] and tetraphenylporphyrin (BTPP) [5]. © Urban & Vogel GmbH

Impact of grain boundaries on properties of mullite as a solid electrolyte
(Elsevier, 1994) Yamana, K; Miyamoto, M; Doi, K; Arahori, T; Nowotny, J
Basic properties of muUite such as chemical composition, phase stability, crystalline structure and microstructure are briefly reviewed. Effect of impurities, resulting in the formation of grain boundary glassy precipitates on high temperature properties such as mechanical properties and ionic conductivity is considered. Properties of mullite which is free of the glassy phase are analyzed as an ionic conductor for high temperature oxygen sensors. Electromotive force (EMF) of an oxygen concentration cell, based on mullite (which is free of impurities or involving an excess of silica) as an oxygen conductor, indicates that the electronic conductivity component at high temperatures assumes negligible values especially at very low oxygen activities (below 5ppm). © 1995 Elsevier B.V.
