This paper introduces “Grounded in Place: Dialogues between First Nations Artists from Australia, Taiwan and, Aotearoa,” a special issue of Pacific Arts. It provides background information about the October 2021 online symposium of the same name, which brought together nineteen First Nations artists, filmmakers, and curators, along with non-Indigenous scholars and museum professionals, from Australia, Taiwan, Aotearoa New Zealand, and the Philippines. The symposium explored the relationships that First Nations creative practitioners in the Indo-Pacific region have to the land and sea. Each symposium speaker discussed their creative practice in relation to their panel’s theme: history and sovereignty, land and community, site and materials, or place and space. The journal issue comprises written and visual essays, an interview, poetry, and reflective pieces from symposium participants. The contributions are based on the participants’ presentations and have been expanded. While acknowledging the different political, social, and environmental contexts of each contributor, as well as their highly distinctive perspectives and creative approaches, some common themes have emerged in this volume, which the guest editors outline in this introduction. These centre on First Nations Peoples’ complex relationships with land and water as sites of appropriation and struggles for sovereignty, as sources of learning and creative production, and as places of ancestral being and continuous belonging, community, and culture. The introduction provides a brief overview of each contributor’s essay, as well as background on the collaboration between the institutions that convened the symposium: Queensland University of Technology, Taiwan’s National Museum of Prehistory, and Aotearoa’s Govett-Brewster Art Gallery | Len Lye Centre. It also fleshes out some of the similarities between the countries’ histories, particularly the ongoing effects of colonisation upon their respective First Nations Peoples.

This essay introduces the second section of “Grounded in Place: Dialogues between First Nations Artists from Australia, Taiwan and, Aotearoa,” a special issue of Pacific Arts. “Land and Community” includes papers written by First Nations artists Judy Watson (Australia), Akac Orat (Taiwan), and Areta Wilkinson (Aotearoa New Zealand). These artists discuss their recent works that investigate the land and water as sources of learning, places of ancestral affiliation, parts of their community and ethnic identity, sites of contestation, and places through which to assert sovereignty in the face of the lasting effects of coloni s ation.

The measurement of 55Fe and 63Ni is of great significance for the monitoring of liquid effluents from nuclear power plant. In this paper, a combined analysis method of 55Fe and 63Ni in liquid effluent sample is established. 55Fe and 63Ni are enriched by precipitation of iron hydroxide and nickel hydroxide and separated by TRU resin and nickel resin, then measured by low-level liquid scintillation spectrometer. Also the relevant measurement conditions are analyzed and studied. When the amount of sample is 1.0 L and the measurement time is 60 min, the detection lower limit of this method is 0.06 Bq/L for 55Fe and 0.02 Bq/L for 63Ni, which meets the analysis requirements of 55Fe and 63Ni in liquid effluents of nuclear power plant.

Abstract Recently, all‐solid‐state sodium batteries (Na‐ASSBs) have received increased interest owing to their high safety and potential of high energy density. The potential of Na‐ASSBs based on sodium superionic conductor (NASICON)‐structured Na3V2(PO4)3(Na3VP) cathodes have been proven by their high capacity and a long cycling stability closely related to the microstructural evolution. However, the detailed kinetics of the electrochemical processes in the cathodes is still unclear. In this work, the sodiation/desodiation process of Na3VP is first investigated using in situ high‐resolution transmission electron microscopy (HRTEM). The intermediate Na2V2(PO4)3 (Na2VP) phase with the P21/c space group, which would be inhibited by constant electron beam irradiation, is observed at the atomic scale. With the calculated volume change and the electrode–electrolyte interface after cycling, it can be concluded that the Na2VP phase reduces the lattice mismatch between Na3VP and NaV2(PO4)3 (NaVP), preventing structural collapse. Based on the density functional theory calculation (DFT), the Na+ ion migrates more rapidly in the Na2VP structure, which facilitates the desodiation and sodiation processes. The formation of Na2VP phase lowers the formation energy of NaVP. This study demonstrates the dynamic evolution of the Na3VP structure, paving the way for an in‐depth understanding of electrode materials for energy‐storage applications.
