      abstract     = {The dynamics of active colloids is very sensitive to the
                      presence of boundaries and interfaces which therefore can be
                      used to control their motion. Here we analyze the dynamics
                      of active colloids adsorbed at a fluid-fluid interface. By
                      using a mesoscopic numerical approach which relies on an
                      approximated numerical solution of the Navier-Stokes
                      equation, we show that when adsorbed at a fluid interface,
                      an active colloid experiences a net torque even in the
                      absence of a viscosity contrast between the two adjacent
                      fluids. In particular, we study the dependence of this
                      torque on the contact angle of the colloid with the
                      fluid-fluid interface and on its surface properties. We
                      rationalize our results via an approximate approach which
                      accounts for the appearance of a local friction coefficient.
                      By providing insight into the dynamics of active colloids
                      adsorbed at fluid interfaces, our results are relevant for
                      two-dimensional self assembly and emulsion stabilization by
                      means of active colloids.},
