It is made up of ions of one charge type which are fixed to the surface of the solid and an equal number of mobile ions of the opposite charge which are distributed through the neighboring region of the liquid.
2. The area of a charge separation formed when an electrode meets an ionic conductor.A metal electrode in a water solution forms a specific structure consisting of the metal surface itself, an adjoining layer of adsorbed (adhesion to the surfaces of solids) water molecules and ions, and an outer region of oppositely charged ions diffused in the liquid.
This causes an electric field of considerable intensity.
3. An interfacial region, near the boundary between two different phases of a substance, in which physical properties change significantly.4. A structure that appears on the surface of a charged object when it is placed into a liquid.
This object might be a solid particle, a gas bubble, a liquid droplet, or a porous body.
2. A type of electron paramagnetic resonance spectroscopy permitting greatly enhanced resolution, in which a material is simultaneously irradiated at one of its frequencies and by a second oscillatory field during which its frequency is swept over the range of nuclear frequencies.
Someone needs to explain how a state employee who retired after more than thirty-four years and then returned to work nine years later, was able to get by with double dipping (drawing two separate incomes at the same time) by receiving nearly $85,000 in one year, or two and half times more than she did before she retired.
2. A system containing two or more stars.
In a true double, the stars are physically close to each other; in an optical double, they lie in approximately the same direction from the earth and so appear close to each other, but are actually far apart.
