Active colloids, that consume energy to move, hold similar potential for man-made materials controlled by forces generated from within. Yet, their use as a powerhouse in materials science lacks. Here we show a massive acceleration of the annealing of a monolayer of passive beads by moderate addition of self-propelled microparticles. We rationalize our observations with a model of collisions that drive active fluctuations and activate the annealing. The experiment is quantitatively compared with Brownian dynamic simulations that further unveil a dynamical transition in the mechanism of annealing. Active dopants travel uniformly in the system or co-localize at the grain boundaries as a result of the persistence of their motion. Our findings uncover the potential of internal activity to control materials and lay the groundwork for the rise of materials science beyond equilibrium.","lang":"eng"}],"volume":10,"_id":"9060","oa":1,"scopus_import":"1","publication_status":"published","language":[{"iso":"eng"}],"publication":"Nature Communications","pmid":1,"file":[{"relation":"main_file","file_size":2820337,"checksum":"70c6e5d6fbea0932b0669505ab6633ec","access_level":"open_access","date_created":"2021-02-02T13:47:21Z","date_updated":"2021-02-02T13:47:21Z","success":1,"content_type":"application/pdf","creator":"cziletti","file_name":"2019_NatureComm_Ramananarivo.pdf","file_id":"9061"}],"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","article_processing_charge":"No","publisher":"Springer Nature","day":"29","external_id":{"pmid":["31358762"],"arxiv":["1909.07382"]},"license":"https://creativecommons.org/licenses/by/4.0/","status":"public","author":[{"full_name":"Ramananarivo, Sophie","last_name":"Ramananarivo","first_name":"Sophie"},{"first_name":"Etienne","last_name":"Ducrot","full_name":"Ducrot, Etienne"},{"id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","full_name":"Palacci, Jérémie A","last_name":"Palacci","first_name":"Jérémie A","orcid":"0000-0002-7253-9465"}],"oa_version":"Published Version","date_updated":"2023-02-23T13:47:59Z","article_type":"original","type":"journal_article","has_accepted_license":"1","doi":"10.1038/s41467-019-11362-y","issue":"1","ddc":["530"],"article_number":"3380","quality_controlled":"1","title":"Activity-controlled annealing of colloidal monolayers","keyword":["General Biochemistry","Genetics and Molecular Biology","General Physics and Astronomy","General Chemistry"],"intvolume":"        10","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"citation":{"apa":"Ramananarivo, S., Ducrot, E., &#38; Palacci, J.
