The driving torque arises from the diffusiophoretic effect induced by the concentration gradients generated by catalytic chemical reactions at the gear surface. This torque produces a spontaneous and unidirectional rotation of the asymmetric gear. By means of mesoscopic simulations, we prove and characterize this scenario. The gear rotational velocity is determined by the gear-solvent interactions, the gear geometry, the solvent viscosity, and the catalytic reaction ratio. Our work presents a simple way to design self-propelled microrotors, alternative to existing catalytic bi-component, or thermophoretic ones.}, cin = {IAS-2 / ICS-2}, ddc = {540}, cid = {I:(DE-Juel1)IAS-2-20090406 / I:(DE-Juel1)ICS-2-20110106}, pnm = {551 - Functional Macromolecules and Complexes (POF3-551)}, pid = {G:(DE-HGF)POF3-551}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000349614200038}, pubmed = {pmid:25662663}, doi = {10.1063/1.4906823}, url = {https://juser.fz-juelich.de/record/188021}, }
