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.

Surface restructuring of zeolite-encapsulated halide perovskite to activate lattice oxygen oxidation for water electrolysis
(Wiley, 2023-05-26) Ren, XG; Zhai, YY; Wang, PJ; Xu, Z; Gao, SQ; Chen, X; Gu, QF; Wang, BL; Li, JY; Liu, SZ
Metal‐halide perovskites possess great potential for electrochemical water splitting that has not been realized due to their intolerance to water. Here, methylammonium lead halide perovskites (MAPbX3) are used to electrocatalyze water oxidation in aqueous electrolytes by creating MAPbX3@AlPO‐5 host–guest composites. Due to the protective feature of the zeolite matrix, halide perovskite nanocrystals (NCs) confined in aluminophosphate AlPO‐5 zeolites achieve an excellent stability in water. The resultant electrocatalyst undergoes dynamic surface restructuring during the oxygen evolution reaction (OER) with the formation of an edge‐sharing α‐PbO2 active layer. The existence of charge‐transfer interactions at the MAPbX3/α‐PbO2 interface significantly modulates the surface electron density of the α‐PbO2 and optimizes the adsorption free energy of oxygen‐containing intermediate species. Furthermore, the soft‐lattice nature of halide perovskites enables more facile triggering of lattice‐oxygen oxidation of nanostructured α‐PbO2, exhibiting pH‐dependent OER activity and non‐concerted proton‐electron transfer for MAPbX3@AlPO‐5 composite. As a result, the developed MAPbBr3@AlPO‐5 composite manifests an ultralow overpotential of 233 mV at 10 mA cm−2 in 1 m KOH. These findings offer facile access to halide perovskite applied to water electrolysis with enhanced intrinsic activity, providing a new paradigm for designing high‐efficiency OER electrocatalysts. © 2025 Advanced journals portfolio

N-doped graphitic carbon encapsulating cobalt nanoparticles derived from novel metal–organic frameworks for electrocatalytic oxygen evolution reaction
(Elsevier, 2023-08) Tian, YM; Wu, H; Hanif, A; Niu, YL; Yin, Y; Gu, YY; Chen, ZF; Gu, QF; Ng, YH; Shang, J; Li, Liangchun; Liu, Mingxian
Nitrogen-doped carbon catalysts with hierarchical porous structure are promising oxygen evolution reaction (OER) catalysts due to the faster mass transfer and better charge carrying ability. Herein, an exquisite high nitrogen-containing ligand was designed and readily synthesized from the low-cost biomolecule adenine. Accordingly, three new MOFs (TJU-103, TJU-104 and TJU-105) were prepared using the Co(II) or Mn(II) ions as metal nodes. Through rationally controlling pyrolysis condition, in virtue of the high nitrogen content in well-defined periodic structure of the pristine MOFs, TJU-104–900 among the derived MOFs with hierarchical porous structure, i.e., N-doped graphitic carbon encapsulating homogeneously distributed cobalt nanoparticles, could be conveniently obtained. Thanks to the synergistic effect of the hierarchical structure and well dispersed active components (i.e., C=O, Co‒Nx, graphitic C and N, pyridinic N), it could exhibit an overpotential of 280 mV@10 mA/cm2 on carbon cloth for OER activity. This work provides the inspiration for fabrication of nitrogen-doped carbon/metal electrocatalysts from cost-effective and abundant biomolecules, which is promising for practical OER application. © 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

Direct air capture of CO2 by metal cation‐exchanged LTA zeolites: effect of the charge‐to‐size ratio of cations
(Wiley, 2023-05-17) Tao, ZY; Tian, YM; Ou, SY; Gu, QF; Shang, J
Direct air capture of CO2 (DAC) has been increasingly recognized as a promising carbon‐negative technology. The challenge in deploying energy‐efficient DAC lies in effective sorbent materials. In this research, we comprehensively investigated the DAC behavior of LTA zeolites exchanged with different metal cations (Na+, K+, Mg2+, Ca2+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Y3+, La3+, Ce3+, Eu3+, Tb3+, and Yb3+) by both static single‐component gas adsorption and dynamic mixture gas adsorptive separation tests. We found that a large charge‐to‐size ratio of cations is critical to imparting a high DAC capacity of LTA zeolites, which is ascribed to the enhanced electrostatic interaction and/or π‐back bonding toward CO2. Meanwhile, a detrimental effect is associated with an excessively large charge‐to‐size ratio, that is, a significant “shielding effect” of (pre‐) adsorbed contaminants (e.g., H2O and CO2) on cations (e.g., Mn2+ and Mg2+) reduce the accessible CO2 capacity. Ca‐LTA featuring Ca2+ with an appropriate charge‐to‐size ratio exhibits the highest DAC capacity (350 ppm CO2 in the air, 1.20 mmol/g) with fast kinetics and good reusability. These results provide valuable insights for the design of zeolites‐based physisorbents for DAC. © 2025 American Institute of Chemical Engineers

Multiple modulation of magnetism in two-dimensional FeCl2/In2Se3 van der Waals heterostructure
(AIP Publishing, 2023-07-24) Jin, C; Liu, C; Ren, FZ; Wang, B; Sun, Wei; Jia, ML; Gu, QF
The effective modulation of magnetism for two-dimensional (2D) materials not only has potential applications in nanoscale spintronic devices but also has urgent demands in modern industries. In this work, we report the discovery of ferroelectrically (FE) tunable orbital reconstruction in FeCl2/In2Se3 2D van der Waals (vdWs) heterostructures (HSs), which leads to a transition from ferromagnetic (FM) order to ferrimagnetic order (intra-layer magnetic coupling is AFM3 arrangement). The reversible FE polarization not only enables the easy magnetization axis to be tuned from the out-of-plane to in-plane direction but also reduces the net magnetization strength from 31.87 to −0.18 μB/f.u. Based on the charge density differences and the density of states analysis, the preference of FM and AFM3 arrangement can be reasonably explained by the Goodenough–Kanamori–Anderson rule. The ferroelectric switching enables nonvolatile electric control of magnetic order and anisotropy, offering significant potential for high-efficiency nanodevices and nonvolatile information storage. Moreover, modulation of magnetism (magnetic moment from −0.18 to 0.18 μB/f.u.) can also be achieved through interlayer sliding in the −P case, providing a way to control magnetism in 2D vdWs HSs. © 2025 AIP Publishing LLC

The effects of Sb on the lattice and microstructure characteristics of hypo-eutectic Sn-Bi alloys
(Elsevier, 2023-07) Tan, XF; Hao, QC; Gu, QF; McDonald, SD; Sweatman, K; Bermingham, M; Nogita, K
Sn-Bi alloys emerged as promising candidates for low temperature solder materials due to their low cost and low liquidus temperature. However, the Sn-Bi solders tend to have low ductility at high strain rates. The addition of Sb is found to improve the ductility of Sn-Bi alloys and they have recently received strong commercial interest. This study employs scanning electron microscopy (SEM), electron probe microanalysis (EPMA), in-situ heating synchrotron powder X-ray diffraction (PXRD) and cooling curve analysis of solidification events to investigate the effects of Sb on the microstructure, crystal structure and solidification behaviour of hypoeutectic Sn-37wt%Bi-xSb alloys, where x is up to 3 wt%. Calculations of phase diagrams (CALPHAD) and density functional theory (DFT) simulations are used to predict the phases and to calculate the energy of formation. It was found that Sb does not necessarily refine the microstructure of Sn-37wt%Bi. Between room temperature and 120 °C, the lattice parameters of both Sn and Bi are dependant on temperature and Sb concentration. However, the effect of temperature on the relationship between Sb concentration and the lattice parameters differs, being more complex for the Sn phase. A concentration of 0.5 wt% Sb was found to result in the lowest energy of formation during the dissolution/precipitation of Bi. © 2023 Elsevier Inc
