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.

Defect control and ionic conductivity of oxynitride perovskite Sr0.83Li0.17Ta0.83O1.88N0.74
(Elsevier, 2022-01) Kim, YI; Avdeev, M
Perovskite lattice was tailored by introducing site vacancies and mixed anion composition, to produce Sr0.83Li0.17Ta0.83O1.88N0.74 (Li02N). Further, Li02N was converted to a defect oxide Sr0.83Li0.17Ta0.83O3 (Li02O) by applying an optimized treatment: heating in air at 1173 K for 2 h. According to the neutron Rietveld refinement, Li02N and Li02O are tetragonal and orthorhombic, respectively, where the lattice volume of Li02O is significantly smaller than that of Li02N. The ionic conductivity (σion) of Li02N and Li02O was evaluated by the ac impedance spectroscopy and the equivalent circuit analysis. Both Li02N (σion = 10−5.5 S/cm at 671 K) and Li02O (σion = 10−6.2 S/cm at 667 K) exhibited an Arrhenius behavior of ionic conductivity with activation energies of 0.87 eV and 0.75 eV, respectively. It is interpreted that the nitride component enhances the ionic conduction of Li02N, while the vacancy of the anion lattice makes an opposite effect. © 2021 Elsevier Ltd and Techna Group S.r.l.

Role of a-site molecular ions in the polar functionality of metal–organic framework perovskites
(American Chemical Society (ACS), 2021-12-28) Lu, T; Cortie, DL; Li, ZX; Narayanan, N; Liu, Z; Sun, QB; Frankcombe, TJ; McIntyre, GJ; Yu, D; Liu, Y
Recent studies on organic–inorganic hybrid perovskites (OIHPs) and ferroelectric metal–organic framework perovskites (MOFPs) reveal their superb performance as highly efficient materials for photovoltaics and ferroelectrics. This has enabled the development of a new generation of optic-electronic-mechanical devices based on green chemistry. However, the fundamental understanding of these polarization-related functionalities is not yet clear, which has hindered the progress in further designing and developing materials with expected properties. In this work, we investigate three MOFPs that have the same Mg(HCOO)3– frameworks with different molecular ions: [CH3NH3][Mg(HCOO)3] (MA-MOF), [(CH3)2NH2][Mg(HCOO)3] (DMA-MOF), and [C(NH2)3][Mg(HCOO)3] (GUA-MOF). Single-crystal and powder X-ray diffraction, inelastic neutron spectroscopy, and ab initio molecular dynamics simulations are combined to achieve a detailed description of the three MOFPs’ static and dynamic structures as a function of temperature. Intriguingly, our study reveals that the alignments and motions of the guest molecular ions are highly dependent on the directional hydrogen bonds that link N–H units to the surrounding MgO6 octahedra through the O acceptor from the frameworks. At the same time, the size, dynamic behavior, and alignments of the A-site molecular ions influence the distortive framework structures and their temperature-dependent deformation. Therefore, the mutual interaction between the guest and the framework determines the overall functionalities of the MOFPs. This study indicates that the configuration of the A-site molecular ions and the potential hydrogen bonds are critical to design the polar functionalities in both MOFPs and OIHPs. © 2021 American Chemical Society

Interplay of local polarization, ionic size, and octahedral tilt in SrTiO3-Na0.5Bi0.5TiO3
(American Physical Society (APS), 2024-01-01) Sharma, D; Punetha, P; Adhikary, GD; Avdeev, M; Ranjan, R
We show that the ferroelectric system (1−x) SrTiO3−(x) Na0.5Bi0.5TiO3 exhibits an interesting interplay of local polarization, ionic size effect, and octahedral tilt. This interplay results in (i) a nonmonotonic composition dependence of the lattice volume at room temperature and (ii) existence of a unique temperature (300∘C) at which the competing effects of electrostriction caused by the formation of polar nanoregions and geometrical ionic size make the system exhibit composition independent lattice parameters in a large composition interval x<0.40. ©2024 American Physical Society.

ANSTO research impact report : covers highlights from the period 2016-2022 at ANSTO
(Australian Nuclear Science and Technology Organisation, 2023-11) Australian Nuclear Science and Technology Organisation
The Research Impact Report shows some of the many ways that science at ANSTO has delivered real world benefits in recent years. It is important not only to do great science but to be seen to be doing great science, so we deliver this report in the spirit of accountability: to the government; to other funders and supporters who made this research possible; and to the public, who ultimately reap the rewards. The case studies presented in the report deliver benefit and represent a significant intellectual achievement from ANSTO scientists in collaboration with users, partners, and industry clients. Our research, and the research of those who access our infrastructure, relies on nuclear science and technology that can only be delivered by ANSTO. Science at ANSTO brings public benefit to all Australians, in areas of national priority and in alignment with national science and research priorities, through innovation for industry, improving health, protecting the environment, optimising the nuclear fuel cycle, supporting Indigenous cultural heritage, enhancing food and agriculture, and fostering discovery. When you browse through this library of almost a hundred case studies, you will also find details of ANSTO’s advanced capabilities, and, importantly, a list of the individuals who contributed to the research. Whether it is coming up with the concept or theory, conducting the experiment, interpreting the results or translating the science into a technology, the effort is a shared one. We applaud these efforts and celebrate the achievements captured in the case studies. At a time when excellent science is needed to help resolve opportunities and challenges for the nation, ANSTO is proud to have delivered on its mandate in delivering knowledge and advancing prosperity for the benefit of Australia.
