Schematic representation of a Janus particle with its catalytic (C) and noncatalytic (N) hemispheres where the surface reaction (1) takes place between fuel and product supplied by the solution surrounding the particle. The particle is also subjected to some external force and torque . The position of its center of mass is , and is the unit vector giving its orientation and pointing in the direction of the catalytic hemisphere.
