● A streaming current and streaming potential are two interrelated electro kinetic phenomena studied in the areas of surface chemistry and electrochemistry.
● Streaming potential is opposite to electro osmosis.
● When an electrolyte solution is forced to flow through a stationary capillary or a porous plug, an electrical potential difference will be produced between the two ends of capillary or porous plug.
● This electrical potential difference is referred to as streaming potential, which means the liquid carries away the ions with the charge opposite to the surface, giving rise to a streaming current, consequently, leading to the accumulations of charge at the ends and an electrical field.
● The IIT team employed “electro-kinetic streaming potential” to harvest energy from flowing tap water and “contrasting inter-facial activities” entailing different types of semiconducting materials to generate power from stagnant water
