--- res: bibo_abstract: - Molecular motors are essential to the living, generating fluctuations that boost transport and assist assembly. 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Sophie foaf_name: Ramananarivo, Sophie foaf_surname: Ramananarivo - foaf_Person: foaf_givenName: Etienne foaf_name: Ducrot, Etienne foaf_surname: Ducrot - foaf_Person: foaf_givenName: Jérémie A foaf_name: Palacci, Jérémie A foaf_surname: Palacci foaf_workInfoHomepage: http://www.librecat.org/personId=8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d orcid: 0000-0002-7253-9465 bibo_doi: 10.1038/s41467-019-11362-y bibo_issue: '1' bibo_volume: 10 dct_date: 2019^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/2041-1723 dct_language: eng dct_publisher: Springer Nature@ dct_subject: - General Biochemistry - Genetics and Molecular Biology - General Physics and Astronomy - General Chemistry dct_title: Activity-controlled annealing of colloidal monolayers@ fabio_hasPubmedId: '31358762' ...
