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.

Air mass characterisation at Cheju Island, South Korea during ACE-Asia
(Royal Australian Chemical Institute & Australasian Society of Ecotoxicology, 2002-07-21) Swan, H; Zahorowski, W
The International Global Atmospheric Chemistry Aerosol Characterisation Experiment, Asia (ICAG ACE-Asia) intensive operational phase (IOP) was conducted from March to May 2001 to better understand the chemical, physical, and radiative properties of atmospheric aerosols and ultimately the climatic effects of aerosols in the Asian region. The authors participated in the ACE-Asia IOP to obtain dimethylsulphide (DMS), carbon disulphide (CS2) and 222radon (Rn) gas-phase measurements from Kosan on Cheju Island, the main ground-site sampling platform. DMS is a product of the activity of phytoplankton and is a major natural source of sub-micron sulfate aerosol. The atmospheric lifetime of DMS is ~1 day and is therefore a biogenic trace sulphur gas indicative of recent oceanic air. CS2 is a trace sulphur gas associated with combustion and is an indicator of anthropogenic pollution events. DMS and CS2 were measured The International Global Atmospheric Chemistry Aerosol Characterisation Experiment, Asia (ICAG ACE-Asia) intensive in real-time using automated cryogenic concentration with GC/PFPD analysis. The sampling frequency was 22 minutes and the limit of detection (LOD) was S 5 ng (as S)/m3 . The average DMS and CS2 concentrations for IOP DOY 95-116 were 29 and 21 ng (as S)/m3, respectively. DMS and CS2 ranged from the LOD to 164 and 176 ng (as S)/m3, respectively. The expanded relative measurement uncertainty (at 95% ci) for the dataset collected was 9.4%. Rn, a decay product of 238U, has a naturally occurring terrestrial origin with concentrations in air over land —102-103 times greater than in oceanic air masses. Rn, being a noble gas, does not react chemically with other species and its predominant sink is by radioactive decay. The half-life of Rn is 3.8 days and is a good indicator of recent air mass contact with land. The Rn detector at Kosan has a LOD of S 40 nBq/m3 and a response time of ~45 minutes, and hourly averaged Rn concentrations were used for analysis. The average Rn concentration at Kosan for the IOP during the 95th to 116th day of the year (Julian day) was 2943 mBq/m3, ranging from 1183 to 6229 mBq/m3 Analysis details, data collected for the IOP and specific events identified will be presented. These measurements, in combination with other chemical and physical aerosol measurements made by other research groups, will be used to assist air mass determine aerosol properties and test climate models.

Stability of charge-stripe ordered La2−xSrxNiO4+δ at one third doping
(Elsevier, 2018-05) Freeman, PG; Mole, RA; Christensen, NB; Stunault, A; Prabhakaran, D
The stability of charge ordered phases is doping dependent, with different materials having particularly stable ordered phases. In the half filled charge ordered phases of the cuprates this occurs at one eighth doping, whereas in charge-stripe ordered La2−xSrxNiO4+δ there is enhanced stability at one third doping. In this paper we discuss the known details of the charge-stripe order in La2−x SrxNiO4+δ, and how these properties lead to the one third doping stability. © 2017 Elsevier B.V.

The magnetic properties of single-crystalline atacamite, Cu2Cl(OH)3
(Elsevier, 2018-05-01) Heinze, L; Beltran-Rodriguez, R; Bastien, G; Wolter, AUB; Reehuis, M; Hoffmann, JU; Rule, KC; Süllow, S
We present susceptibility measurements on the natural mineral atacamite, Cu2Cl(OH)3, for the first time along the three crystallographic axes. Further, we have carried out an elastic neutron diffraction experiment which shows that the symmetry of the magnetic ground state of atacamite is described by a propagation vector q=(1/2 0 1/2). © 2017 Elsevier B.V.

A fast switching electrostatic deflector system for actinide isotopic ratio measurements
(Elsevier, 2010-04) Zorko, B; Child, DP; Hotchkis, MAC
We have implemented a fast switching electrostatic system on the actinides beamline on the ANTARES accelerator at ANSTO, to improve the precision of analyses by accelerator mass spectrometry. This high-energy bouncing system is based on a pair of deflector plates, deflecting in the orbit plane, set at the entrance and exit of the analysing magnet. The design of deflector plates is unique, and it was modelled by SIMION in order to minimize field inhomogenity and fringe field effects. The pair of deflector plates are supplied by a high-voltage amplifier driven by an EPICS-enabled control unit, with two 4 W power supplies providing up to ±10 kV modulation. The high-energy bouncing system is synchronized with the existing low-energy bouncing system. To measure the isotopic ratio with the new system, the magnetic fields of the injector and analysing magnets are set to transmit selected isotopes along the beam line with zero voltage applied. The other isotopes of interest are transmitted by keeping the magnetic fields constant and modulating the voltages on the injector magnet chamber and on the high-energy deflector plates. © 2009 Elsevier B.V.

EPR spectra and lithogeochemistry of jasperoids at Carlin, Nevada: distinction between auriferous and barren rocks
(Elsevier, 1995-12) van Moort, JC; Hotchkis, MAC; Pwa, A
The acid insoluble residue of twenty-nine gold-bearing and ten barren jasperoids from Carlin, Nevada, were analysed by electron paramagnetic resonance powder spectroscopy (EPR), and by simultaneous proton-induced X-ray emission (PIXE) and proton-induced gamma ray emission (PIGME) spectroscopy. The mineralised samples are characterised by high Li, F, AI, K, Ti, Rb, V, Y, and Zr values in general and by significantly higher Rb/Al and V/Al ratios in particular. The chemical differences are largely caused by the abundance and type of sericite present. Significant differences in EPR intensity exist between the mineralised and barren jasperoids. © 1995 Published by Elsevier B.V.
