Dispersion of Carbon Nanotubes
to break apart the Van der Waals physical bonds which make the SWNTs agglomerate into bundles. Since SWNTs are such a fine particle, the agglomerated bundles are harder to disperse. We also recommend using a magnetic stirrer for mechanical agitation to assist the dispersion process. cheaptubes.com

Physical properties of CdS/ITO thin films growth by CBD technique with substrate oscillating agitation
mention the importance of the chemical bath agitation, arguing better films quality. A great variety of agitation techniques for the chemical bath have been reported in the literature, being the magnetic stirrer the most common technique. Ultrasonic waves and microwaves techniques have been recently

Sediment Stabilization and Permeable Barriers with Organoclay
. The sorbent is then dispersed in the water by a shaking mechanism, a magnetic stirrer, or a paddle. After a predetermined time, usually 10 minutes, the solids are allowed to settle, followed by centrifugation. The amount of the remaining contaminant in the water is then determined. This test
