      abstract     = {An asymmetric gear with homogeneous surface properties is,
                      here, presented as a prototype to fabricate catalytic
                      microrotors. 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.},
