Ions moving independently in large space
WebThe Goldman–Hodgkin–Katz flux equation (or GHK flux equation or GHK current density equation) describes the ionic flux across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell. Since both the voltage and the concentration gradients influence the movement of ions, … WebThe Ionosphere Regions of the ionosphere, showing the D, E, and F layers.
