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.

In situ incorporation of nanostructured antimony in an N-doped carbon matrix for advanced sodium-ion batteries
(Royal Society of Chemistry, 2019-04-29) Wu, ZB; Johannessen, B; Zhang, WC; Pang, WK; Mao, JF; Liu, HK; Guo, ZP
Herein, a facile one-step and solvent-free pyrolysis method was developed to control the synthesis of nanostructured Sb embedded in an N-doped carbon matrix (Sb@GxNy-T, where T, Gx and Ny denote the annealing temperature and the mass (g) of glucose and NH4Cl used in the process, respectively). By adjusting these parameters, hybrid architectures can be in situ constructed, including hollow Sb embedded in holeless carbon matrixes (Sb@G0.25N0.5-950) and Sb nanoplates embedded in holey carbon matrixes (Sb@G0.25N0.25-950). Our findings suggest that the formation of diverse nanostructures closely relate to the sublimation and evaporation of Sb, and the structural remold of liquid Sb by surface tension. Benefitting from the unique structural features, these optimized electrodes show highly reversible sodium storage with high specific capacities and good cycling stability. More importantly, this strategy can be further extended to other material systems, such as Sn- and SnO2 nanodots embedded in a holey carbon matrix. This work presents a new scalable methodology to confine/remold nanostructured materials in a carbon matrix which allows for the future design of functional materials with tunable composition and architecture. © Royal Society of Chemistry 2025.

Insights for restoration: reconstructing the drivers of long-term local fire events and vegetation turnover of a tropical peatland in Central Kalimantan
(Elsevier, 2023-10-15) Ramdzan, KNM; Moss, PT; Jacobsen, GE; Gallego-Sala, A; Charman, DJ; Harrison, ME; Page, SJ; Mishra, SK; Wardle, DA; Jaya, A; Aswandi; Nasir, D; Yulianti, N
Fire events in tropical peatlands often relate to dry peat conditions associated with climate variability (drought) and anthropogenic-driven ecosystem degradation. However, drought is not the only driver of long-term fire events and peatland ecosystem changes. This study used palaeoecological and geochemical proxies to investigate the long-term drivers of charcoal influx to identify local fires and examine the associated responses to the tropical peatland ecosystem in Central Kalimantan, Indonesia. The results showed local fire events increased after 756 cal. yr BP, and possible drivers of charcoal influx include changes in sea level, increased frequency of El Niño events, increased biomass, and anthropogenically-driven ecosystem degradation. However, the vegetation composition showed changes since ∼2300 cal. yr BP from a mix of peat swamp forest (PSF) and open vegetation (OV) during the late Holocene (∼2300 to 1129 cal. yr BP), to predominantly PSF from 1128 to 375 cal. yr BP, dry lowland mixed with swamp forest (LMS) and open vegetation (OV) from 374 to 135 cal. yr BP, and predominantly OV and freshwater swamp forest (FSF) from 134 to −62 cal. yr BP. The possible drivers of the vegetation turnover were hydrological conditions and the availability of peat nutrients, while the vegetation turnover affected the accumulation and decomposition of recalcitrant organic matter in peat. The thresholds of the peatland ecosystems over longer-term timeframes provided the following restoration insights: 1) PSF species (i.e. Eurya and Ilex) showed high fire tolerance and increased in abundance up to charcoal influx threshold of ∼23 grains mm−2 cm−3 yr−1 while LMS and OV species increased up to a lower threshold of ∼13 grains mm−2 cm−3 yr−1before declining; 2) PSF species expanded during periods of wet conditions and high peat nutrients (i.e. TN - enriched); and 3) Future revegetation in the region can focus on tree taxa such as Euphorbiaceae, Arenga, Ficus, and Trema as they were historically able to thrive in fire events and dry hydrological conditions. © 2023 Published by Elsevier B.V.

A novel measurement of voidage in coke and ferrous layers in softening and melting under load test using synchrotron X-ray and neutron computed tomography
(Iron and Steel Institute of Japan, 2018-11-15) Liu, XL; Honeyands, T; Mitra, S; Evans, G; Godel, B; Acres, RG; Salvemini, F; O’dea, D; Ellis, B
For the first time, the bed voidage of samples from interrupted softening and melting (S&M) under load tests was measured directly using computed tomography (CT). The large size, fused structure and high metallic iron content of the samples required the very high energy synchrotron X-ray source for scanning; samples produced at higher temperatures, e.g., 1 450°C, required neutron CT to allow adequate penetration of the samples. This method was able to uniquely and accurately identify the volumes, distributions, and structures of coke, ferrous, and void in the S&M samples, and quantify the tortuosity of the voids. This information is critical for analysis of the pressure drop–contraction relationship in the S&M under load test, and will allow the improvement of the treatment of the cohesive zone in numerical models of the blast furnace. © 2018 by The Iron and Steel Institute of Japan.

Tailored fabrication of defect-rich ion implanted CeO2-x nanoflakes for electrochemical sensing of H2O2
(The Electrochemical Society, 2023-05-24) Luo, YY; Zheng, XR; Vutukuri, CV; Ho, N; Atanacio, AJ; Manohar, M; Arandiyan, H; Wang, Y; Sorrell, CC; Mofarah, SS; Koshy, P
As an alternative to H2O2 enzymatic biosensing devices, non-enzymatic CeO2-based biosensors have shown improved sensibility, robustness, and shelf lives. The redox capability in CeO2 and rapid switching between its oxidation states facilitate the formation of structural vacancy defects that serve as active sites. This work reports a novel approach for synthesis of defect-rich CeO2-x-based nanoflakes using a controllable electrochemical-based deposition at low temperatures (45°−65 °C) followed by low-energy ion implantation. Among the nanoflakes, Mo-implanted CeO2-x exhibited outstanding sensitivity of 4.96 × 10−5 A·mM−1 cm−2 within the linear range of 0.05–10 mM. Moreover, the ion-implanted samples yielded high sensing stability and electronic conductivity. The former was achieved through the multi-valence charge transfer between Ce and the implanted ions that caused the reduction of Gibbs free energies required for the formation/retention of the defects. The latter was due to the narrowing of the electronic bandgap of CeO2-x by creation of defect-induced midgap states. © 2023 The Author(s).

Phonon softening and electron-phonon coupling in the topological nodal-line semimetal ZrGeSe
(American Physical Society, 2024-03-07) Zhao, WY; Haque, E; Guo, L; Cortie, DL; Chen, L; Salmankurt, B; Wang, XL; Zheng, RK; Medhekar, NV; Karel, J; Rule, KC
ZrGeSe is one of the most well-known topological nodal-line semimetals, which possesses linearly dispersive electronic bands near the Fermi surface. However, the lattice-dynamics study and its interaction with the electronic system have not been investigated. We employed the inelastic neutron-scattering method to study the lattice dynamics of ZrGeSe single crystals. The measured acoustic phonon dispersions were compared with lattice-dynamics calculations, with an overall good agreement with theory; however, both the longitudinal and the transverse acoustic phonon dispersions along the (𝑞⁢00) directions demonstrate significant softening, unexpectedly in contrast with the theoretical predictions. Complementary ab initio molecular dynamics simulations indicate an anomalous temperature dependency in the vibrational spectroscopy. We show that strong electron-phonon coupling exists along the Γ-𝑀 −𝑋 directions and argue that the phonon softening is induced by such electron-phonon coupling. ©2025 American Physical Society.
