Things I also learned today:
- The Debeye length may be conceptualized as the characteristic size of a fluctuation of the electrostatic potential inside a solution of charged particles. Longer Debeye lengths mean longer distances for which the potential remains roughly the same.
- Surfactants may be used to stabilize a colloidal dispersion. This is different from electrostatic stabilization, whereby some charge is permanently located on/inside the particles to cause them to repel one another.
