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.

Multi-campaign ship and aircraft observations of marine cloud condensation nuclei and droplet concentrations
(Springer Nature, 2023-07-20) Sanchez, KJ; Painemal, D; Brown, MD; Crosbie, EC; Gallo, F; Hair, JW; Hostetler, CA; Jordan, CE; Robinson, CE; Scarino, AJ; Shingler, TJ; Shook, MA; Thornhill, KL; Wiggins, EB; Winstead, EL; Ziemba, LD; Chambers, SD; Williams, AG; Humphries, RS; Keywood, MD; Ward, JP; Cravigan, LT; McRobert, IM; Flynn, C; Kulkarni, GR; Russell, LM; Roberts, GC; McFarquhar, GM; Nenes, A; Woods, SF; Reid, JS; Small-Griswold, J; Brooks, S; Kirschler, S; Voigt, C; Wang, J; Delene, DJ; Quinn, PK; Moore, RH
In-situmarine cloud droplet number concentrations (CDNCs), cloud condensation nuclei (CCN), and CCN proxies, based on particle sizes and optical properties, are accumulated from seven field campaigns: ACTIVATE; NAAMES; CAMP2EX; ORACLES; SOCRATES; MARCUS; and CAPRICORN2. Each campaign involves aircraft measurements, ship-based measurements, or both. Measurements collected over the North and Central Atlantic, Indo-Pacific, and Southern Oceans, represent a range of clean to polluted conditions in various climate regimes. With the extensive range of environmental conditions sampled, this data collection is ideal for testing satellite remote detection methods of CDNC and CCN in marine environments. Remote measurement methods are vital to expanding the available data in these difficult-to-reach regions of the Earth and improving our understanding of aerosol-cloud interactions. The data collection includes particle composition and continental tracers to identify potential contributing CCN sources. Several of these campaigns include High Spectral Resolution Lidar (HSRL) and polarimetric imaging measurements and retrievals that will be the basis for the next generation of space-based remote sensors and, thus, can be utilized as satellite surrogates. © The Authors - Open Access This article is licensed under a Creative Commons Attribution 4.0

The continuum between hexagonal planar and trigonal planar geometries
(ChemRxiv, 2022-03-22) Garcon, M; Phanopoulos, A; Sackman, GA; Richardson, C; White, AJP; Cooper, RI; Edwards, AJ; Crimmin, MR
New heterometallic hydride complexes that involve the addition of {Mg–H} and {Zn–H} bonds to group 10 transition metals (Pd, Pt) are reported. The side-on coordination of a single {Mg–H} to Pd forms a well-defined σ-complex. In contrast, addition of three {Mg–H} or {Zn–H} bonds to Pd or Pt results in the formation of planar complexes with subtly different geometries. We compare their structures through experiment (X-ray diffraction, neutron diffraction, multinuclear NMR), computational methods (DFT, QTAIM, NCIPlot), and theoretical analysis (MO diagram, Walsh diagram). These species can be described as snapshots along a continuum of bonding between ideal trigonal planar and hexagonal planar geometries.

A new evidence base to document millennial changes in coastal vegetation
(Research Square Platform, 2023-10-12) Foster, NR; Jones, AR; Serrano, O; Lafratta, A; Lavery, PL; van Dijk, KJ; Biffin, E; Gillanders, BM; Young, J; Masque, P; Gadd, PS; Jacobsen, GE; Zawadzki, AW; Greene, A; Waycott, M
Anthropogenic activities are causing detrimental changes to coastal plants– namely seagrass, mangrove, and tidal marsh. Looking beyond recent times and to past vegetation dynamics is critical to assess the response and resilience of an environment to change. Here, we develop a novel multi-proxy approach, providing a new evidence base to decipher long-term change in coastal plant communities. Combining targeted environmental DNA analysis with chemical analysis of soils, we reconstructed 4,000 years of change at a temperate wetland and identified an ecosystem shift that occurred between ~ 1000 and 2000 years ago. What was a previous subtidal seagrass system shifted to an intertidal mangrove environment at present. We demonstrate that high-resolution information on millennial changes in coastal vegetation can be attained through these proxies. This approach could be applied to other ecosystems to improve the way we protect, conserve, and restore vegetated ecosystems. © The Authors CC-BY 4.0 - Research Square.

Understanding the solution and solid-state structures of Pd and Pt PSiP pincer-supported hydrides
(American Chemical Society, 2015-11-19) Suh, HW; Balcells, D; Edwards, AJ; Guard, LM; Hazari, N; Mader, EA; Mercado, BQ; Repisky, M
The PSiP pincer-supported complex (CyPSiP)PdH [CyPSiP = Si(Me)(2-PCy2-C6H4)2] has been implicated as a crucial intermediate in carboxylation of both allenes and boranes. At this stage, however, there is uncertainty regarding the exact structure of (CyPSiP)PdH, especially in solution. Previously, both a Pd(II) structure with a terminal Pd hydride and a Pd(0) structure featuring an η2-silane have been proposed. In this contribution, a range of techniques were used to establish that (CyPSiP)PdH and the related Pt species, (CyPSiP)PtH, are true M(II) hydrides in both the solid state and solution. The single-crystal X-ray structures of (CyPSiP)MH (M = Pd and Pt) and the related species (iPrPSiP)PdH [iPrPSiP = Si(Me)(2-PiPr2-C6H4)2] are in agreement with the presence of a terminal metal hydride, and the exact geometry of (CyPSiP)PtH was confirmed using neutron diffraction. The 1H and 29Si{1H}NMR chemical shifts of (CyPSiP)MH (M = Pd and Pt) are consistent with a structure containing a terminal hydride, especially when compared to the chemical shifts of related pincer-supported complexes. In fact, in this work, two general trends relating to the 1H NMR chemical shifts of group 10 pincer-supported terminal hydrides were elucidated: (i) the hydride shift moves downfield from Ni to Pd to Pt and (ii) the hydride shift moves downfield with more trans-influencing pincer central donors. DFT calculations indicate that structures containing a M(II) hydride are lower in energy than the corresponding η2-silane isomers. Furthermore, the calculated NMR chemical shifts of the M(II) hydrides using a relativistic four-component methodology incorporating all significant scalar and spin-orbit corrections are consistent with those observed experimentally. Finally, in situ X-ray absorption spectroscopy (XAS) was used to provide further support that (CyPSiP)MH exist as M(II) hydrides in solution. © 2015 American Chemical Society.

Atomic modulation and structure design of Fe−N4 modified hollow carbon fibers with encapsulated Ni nanoparticles for rechargeable Zn–air batteries
(Wiley, 2022-10-30) Tian, YH; Wu, ZZ; Li, M; Sun, Q; Chen, H; Yuan, D; Deng, D; Johannessen, B; Wang, Y; Zhong, YL; Xu, L; Lu, J; Zhang, SQ
Excellent bifunctional oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) activity and rapid mass transport capability are two important parameters of electrocatalysts for high‐performance rechargeable Zn–air batteries (ZABs). Herein, an efficient atomic modulation and structure design to promote bifunctional activity and mass transport kinetics of an ORR/OER electrocatalyst are reported. Specifically, atomic Fe−N4 moieties are immobilized on premade hollow carbon fibers with encapsulated Ni nanoparticles (Fe‐N@Ni‐HCFs). Synchrotron X‐ray absorption spectroscopy and spherical aberration‐corrected electron microscope analyses confirm the atomic distribution of the active sites and unique lung bubble‐like hollow architecture of the catalyst, while theoretical investigations reveal that the encapsulated Ni nanoparticles can induce electron distribution of the atomic Fe−N4 moieties to reduce reaction energy barriers. As a result, the prepared catalyst possesses enhanced bifunctional ORR/OER activity and well‐constructed gas–solid–liquid interfaces for improved mass transfer. These synergetic advantages endow the binder‐free Fe‐N@Ni‐HCFs electrode with the remarkable power density and cycling stability for ZABs, outperforming the commercial Pt/C+Ir/C benchmark. This exceptional performance suggests that the proposed strategy can be extended to the design and fabrication of electrocatalysts for energy conversion and storage. © 2022 The Authors.
