The QENS measurements resolve atomic-scale dynamics on \u00c5ngstr\u00f6m-length and picosecond timescales, enabling determination of self-diffusion coefficients for liquid natural Ga and Ga-rich alloys (Ga0.98Cu0.02, Ga0.98Pd0.02, and Ga0.98Pt0.02) at T = 873 K. To assess potential hydrogen incorporation, stationary conditions were established with a 0.05 l\/min He\/H2 stream containing 20% H2 at 1.036\u00a0bar. Under these conditions, hydrogen uptake in both liquid pure Ga and the alloys remained well below 0.03 at.\u2009%, indicating negligible intercalation.<\/jats:p>","DOI":"10.1063\/5.0343179","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T10:40:15Z","timestamp":1790851215000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["QENS measurement of hydrogen intercalation from the gas phase into bulk gallium alloys"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8786-3065","authenticated-orcid":false,"given":"Artem","family":"Panchenko","sequence":"first","affiliation":[{"name":"Institute for Crystallography and Structural Physics, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg (FAU) 1 , Staudtstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]},{"name":"Interdisciplinary Center for Nanostructured Films (IZNF) and Center for Nanoanalysis and Electron Microscopy (CENEM), FAU 2 , Cauerstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2019-2137","authenticated-orcid":false,"given":"Klaus","family":"G\u00f6tz","sequence":"additional","affiliation":[{"name":"Institute for Crystallography and Structural Physics, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg (FAU) 1 , Staudtstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]},{"name":"Interdisciplinary Center for Nanostructured Films (IZNF) and Center for Nanoanalysis and Electron Microscopy (CENEM), FAU 2 , Cauerstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3223-072X","authenticated-orcid":false,"given":"Fanni","family":"Juranyi","sequence":"additional","affiliation":[{"name":"PSI Center for Neutron and Muon Sciences 3 , 5232 Villigen PSI,","place":["Switzerland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6818-9159","authenticated-orcid":false,"given":"Igor","family":"Goychuk","sequence":"additional","affiliation":[{"name":"Institute for Crystallography and Structural Physics, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg (FAU) 1 , Staudtstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]},{"name":"Interdisciplinary Center for Nanostructured Films (IZNF) and Center for Nanoanalysis and Electron Microscopy (CENEM), FAU 2 , Cauerstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"B\u00e4r","sequence":"additional","affiliation":[{"name":"Institute for Crystallography and Structural Physics, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg (FAU) 1 , Staudtstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]},{"name":"Interdisciplinary Center for Nanostructured Films (IZNF) and Center for Nanoanalysis and Electron Microscopy (CENEM), FAU 2 , Cauerstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8903-4850","authenticated-orcid":false,"given":"Tobias","family":"Unruh","sequence":"additional","affiliation":[{"name":"Institute for Crystallography and Structural Physics, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg (FAU) 1 , Staudtstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]},{"name":"Interdisciplinary Center for Nanostructured Films (IZNF) and Center for Nanoanalysis and Electron Microscopy (CENEM), FAU 2 , Cauerstra\u00dfe 3, 91058 Erlangen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"2026100106400797600_c1","doi-asserted-by":"publisher","first-page":"862","DOI":"10.1038\/nchem.2822","volume":"9","year":"2017","journal-title":"Nat.
