Coglitore, Diego, Edwardson, Stuart P., Macko, Peter, Patterson, Eann A. and Whelan, Maurice (2017) Data from: Transition from fractional to classical Stokes-Einstein behaviour in simple fluids. [Data Collection]
Description
An optical technique for tracking single particles has been used to evaluate the particle diameter at which diffusion transitions from molecular behaviour described by the fractional Stokes-Einstein relationship to particle behaviour described by the classical Stokes-Einstein relationship. The results confirm a prior prediction from molecular dynamic simulations that there is a particle size at which transition occurs and show it is inversely dependent on concentration and viscosity but independent of particle density. For concentrations in the range 510-3 to 510-6mg/mL and viscosities from 0.8 to 150 mPa s, the transition was found to occur in the diameter range 150 to 300nm.
