Oxygen tracer diffusion coefficients D * and oxygen surface exchange coefficients k * were determined as a function of temperature, 773 ≤ T /K ≤ 1273, at an oxygen activity of a O 2 = 0.1, and as a function of oxygen activity, 0.01 ≤ a O 2 ≤ 0.9, at a temperature of T = 1123 K. Two diffusion processes were observed: a fast diffusion process that is attributed to the interstitialcy diffusion of free oxygen ions (O 2– ) and a slow diffusion process that is attributed to the interstitialcy diffusion of superoxide ions (O 2 – ).","is_dataset_classified":null,"base_score":3.6375861597263857,"endowment":3.6375861597263857,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W2324282985","authors":[],"funders":[{"funder_name":"Deutsche Forschungsgemeinschaft","grant_id":"MA 1090/25-1","title":null},{"funder_name":"Deutsche Forschungsgemeinschaft","grant_id":"unidentified","title":"unidentified"}],"total_grants":2,"fwci":1.2787,"citation_percentile":0.79281627,"influential_citations":0,"citation_trend":[{"year":2015,"count":1},{"year":2016,"count":3},{"year":2017,"count":6},{"year":2018,"count":1},{"year":2019,"count":11},{"year":2020,"count":5},{"year":2021,"count":3},{"year":2022,"count":2},{"year":2023,"count":1},{"year":2024,"count":1},{"year":2025,"count":2},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/jp512863u","host_type":"publisher"},{"url":"https://doi.org/10.1021/jp512863u","host_type":"journal"},{"url":"https://publications.rwth-aachen.de/record/541417","host_type":"repository"},{"url":"https://dx.doi.org/10.1021/jp512863u","host_type":""}],"fields_of_study":["Radioactive element chemistry and processing","Ammonia Synthesis and Nitrogen Reduction","Catalytic Processes in Materials Science","02 engineering and technology","0210 nano-technology","01 natural sciences","0104 chemical sciences"],"mesh_terms":[],"keywords":["Oxygen","Diffusion","Secondary ion mass spectrometry","Ion","Chemistry","Analytical Chemistry (journal)","Diffusion process","TRACER","Oxygen transport","Thermodynamics","Chromatography"],"sdg_mappings":[{"sdg_number":3,"sdg_label":"3.
