The Langevin thermostat was used to perform Brownian Dynamics on a group of particles suspended in an implicit solvent. The time damping parameter of the thermostat was chosen between 5 × 10 -10 s and 1 × 10 -9 s to accurately apply a viscosity correction to the particle according to the solvent in consideration. Simultaneously, the the domain is rescaled to a volume representative of a solid volume fraction of 12.5%. This value was chosen as it is typical of industrial-manufacturers to fabricate catalyst inks with volume fractions in the vicinity. The box was rescaled with the Langevin thermostat holding the system at a fixed temperature. Upon the completion of rescaling, the system was decoupled from the Langevin thermostat to then apply explicit hydrodynamic and brownian interactions using the grand resistance tensor and fluctuation-dissipation theorem detailed above.
