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.
Iontophoresis is to be distinguished from the carriage of uncharged molecules by diffusive fluxes of other molecules, especially of solvent molecules, for example by electro-osmosis, that is to say by flux of uncharged solvent molecules carried as a cross-effect of iontophoresis.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.
