Stokes-Einstein Transition Particle Size Data

Experimental data from an optical particle tracking study measures the particle diameter at which diffusion transitions from fractional to classical Stokes-Einstein behavior. The dataset confirms a prior molecular dynamics prediction, showing the transition size is inversely dependent on concentration and viscosity but independent of particle density. Measurements cover concentrations from 5×10⁻³ to 5×10⁻⁶ mg/mL and viscosities from 0.8 to 150 mPa·s, with transition diameters observed between 150 and 300 nm.

Use Cases

• Analyze the relationship between particle diameter and the transition from fractional to classical diffusion behavior.
• Model the inverse dependence of the transition diameter on solution concentration and viscosity.
• Validate molecular dynamics simulation predictions regarding the existence of a specific particle size for the Stokes-Einstein transition.

Strengths

• Data quantifies a specific transition diameter range of 150 to 300 nm.
• Experimental conditions are well-defined, covering a concentration range from 5×10⁻³ to 5×10⁻⁶ mg/mL and viscosities from 0.8 to 150 mPa·s.
• Results directly test and confirm a prior prediction from molecular dynamics simulations.

Limitations

• The specific data structure (rows, columns, file format) is not described, limiting immediate usability.
• The sample size and granularity of individual measurements are unknown.
• Data is from a single study, limiting generalizability without replication.
