Van Der Waals Forces & Static Electricity

Static Electricity It appears that many of the misunderstandings about spores result from confusing van der Waals forces with static electricity, a.k.a. electrostatic interactions, which are not one of van der Waals forces. Static electricity can be a strong particle to particle binding force, as long as the particles are not of the same substance.
