Applications of Surface Charge
Charged surfaces are extremely important and are used in many applications. For example, solutions of large colloidal particles depend almost entirely on repulsion due to surface charge in order to stay dispersed. If these repulsive forces were to be disrupted, perhaps by the addition of a salt or a polymer, the colloidal particles would no longer be able to sustain suspension and would subsequently flocculate.

Famous quotes containing the words surface and/or charge:
“Nature centres into balls,
And her proud ephemerals,
Fast to surface and outside,
Scan the profile of the sphere;
Knew they what that signified,
A new genesis were here.”
—Ralph Waldo Emerson (1803–1882)
“Those things for which the most money is demanded are never the things which the student most wants. Tuition, for instance, is an important item in the term bill, while for the far more valuable education which he gets by associating with the most cultivated of his contemporaries no charge is made.”
—Henry David Thoreau (1817–1862)
