I confess that I didnât know the geological conventions for abbreviating time until I started teaching the geology writing class and looked them up. (Thatâs despite having published a paper on argon-argon geochronology.
Iontophoresis is a physical process in which ions flow diffusively in a medium driven by an applied electric field.ontophoresis of acetylcholine is used in research as a way to test the health of the endothelium by stimulating endothelium-dependent generation of nitric oxide and subsequent microvascular vasodilation.
This is not a new technique - there is recorded iontophoresis activity way back to the 1700's, though most authorities agree that it was not until the work of Le Duc in the early 1900's that the technique really gained momentum, though its use since that time has been sporadic.
