A streaming current and streaming potential are two interrelated electrokinetic phenomena studied in the areas of surface chemistry and electrochemistry. They are an electric current or potential which originates when an electrolyte is driven by a pressure gradient through a channel or porous plug with charged walls.
The first observation of the streaming potential is generally attributed to the German physicist Georg Hermann Quincke in 1859.
Famous quotes containing the words current and/or streaming:
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a womans adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
“The work was like peeling an onion. The outer skin came off with difficulty ... but in no time youd be down to its innards, tears streaming from your eyes as more and more beautiful reductions became possible.”
—Edward Blishen (b. 1920)
