How does this tool handle concentrated solutions?

The tool applies a correction factor to the Stokes-Einstein equation when a `soluteConcentration` is provided, accounting for increased resistance in crowded environments.

Can I find viscosity values for specific solvents?

Yes, you can use the `get_solvent_properties` tool to retrieve standard viscosity and density constants for common laboratory solvents.

What units are used for the diffusion coefficient?

The diffusion coefficient is returned in square meters per second (m^2/s).

This MCP server provides precision tools for calculating transport kinetics in liquid media. It uses the Stokes-Einstein relation to determine the diffusion coefficient of a solute based on its hydrodynamic radius, the solvent's viscosity, and the absolute temperature. Users can also reverse the calculation to find the solute radius from a known diffusion coefficient or estimate the time required for a particle to travel a specific distance. The server includes concentration corrections for crowded environments and provides access to a catalog of standard solvent properties via get_solvent_properties.
