	U.S. Patent: 5667662 - Electroplating process and composition - September 16, 1997
		The method of claim 1 where the nonconductor is a copper clad printed circuit board substrate having through-holes extending from one of its surfaces to the other of its surfaces.
		This invention relates to electroplating nonconductors, and more particularly, to processes and compositions for electroplating the surface of a nonconductor using a stabilized preformed dispersion of a conductive polymer that functions as a base for direct electroplating when adsorbed onto a nonconducting surface.
		Nonconducting surfaces are conventionally metallized by a sequence of steps comprising catalysis of the surface of the nonconductor to render the same catalytic to electroless metal deposition followed by contact of said catalyzed surface with a plating solution that deposits metal over the catalyzed surface in the absence of an external source of electricity.

	Nonconductor - Wikipedia, the free encyclopedia
		Since air is a nonconductor, no other substance is needed to "keep the electricity within the wires." However, wires which touch each other will produce cross connections, short circuits, and fire hazards.
		In high voltage systems containing transformers and capacitors, liquid nonconductor oil is the typical method used for preventing sparks.
		Nonconductors suffer from the phenomenon of electrical breakdown.

	Reference.com/Encyclopedia/Nonconductor
		Nonconductors or electrical insulators are materials which lack movable electric charges, and which therefore lack a low-resistance path for charge flow.
		When a difference in electrical potential is placed across a nonconductor, no free charges are exposed to the electric field, so no flow of charges appears, and an electric current cannot arise.
		Nonconductors are commonly used as a flexible coating on electric wire and cable.

	Microwaving in a carousel with magnetrons below a food product isolated by a nonconductor - Patent 6294773

	Method for embodying an electric circuit on an active element of an MIS integrated circuit - Patent 5246882
		But having regard to the thickness of the nonconductor to be etched, the final diameter d of the electric contact hole 24 is usually wider than that of the opening 20, that is about 1.mu.m.
		In the case of an anisotropic etching of the first nonconductor, the control of the width of the contact hole in its lower portion is much more precise than in the prior art since it is effected in a thin crash film.
		The electric nonconductors may be embodied from a large number of materials, such as non-doped silicon oxide, silicon nitride, silicon oxinitride, silicated glass doped with phosphorus or borosilicated glass doped with phosphorus.

	electricity
		Materials in which the electrons are tightly bound to the atoms are known as insulators, nonconductors, or dielectrics.
		Three methods may be used to charge an object electrically: (1) by contact with another object of dissimilar substance (such as contact between amber and fur), followed by separation; (2) by contact with another charged body; and (3) by induction.
		In the nonconductor, C, the electrons are not free to move, but the atoms or molecules of the nonconductor reorient themselves so that their constituent electrons are as far as possible from A; the nonconductor is also attracted to A, but to less of an extent than the conductor.

	Diamonds \| American Museum of Natural History
		Both diamond and graphite have important applications in electronics: Diamond may be used as either an insulator (nonconductor) or a semiconductor, and graphite is commonly used as a conductor.
		A substance is an electrical conductor if very little energy is required to move an electron from its bonded condition -- in the so-called valence band -- to a mobile condition in the conduction band.
		In nonconductors (insulators) a large energy barrier exists between the valence band and the conduction band.

	ELECTRICITY,
		The effect of electrical charges on conductors and nonconductors is shown in Fig.
		Under ordinary conditions all substances, conductors as well as nonconductors, offer some opposition to the flow of an electric current, and this resistance necessarily limits the current.
		The unit used for expressing the quantity of resistance is the ohm (Ω), which is defined as the amount of resistance that will limit the flow of current to 1 amp, in a circuit with a potential difference of 1 V. This relationship is known as Ohm's law and is named after the German physicist

		The amount of charge is calculated by measuring the distance the leaves are forced apart.
		In the nonconductor, C, the separation of charge is limited to the way in which the electrons redistribute themselves within an atom.
		This effect is most noticeable if the nonconductor is close to the charged object.

	UA - MiTAC 1 - Prof. Dr. R. Van Grieken
		Because the material under investigation acts as a cathode in the discharge, one of the main challenges for glow discharge spectroscopy is to overcome the intrinsic requirement of the sample to be electrically conducting.
		The effective atomization of the nonconducting sample is thus dependent on the appropriate thickness of the conducting layer: a too thin or incomplete layer causes discharge instabilities due to the charge built-up on the sample surface, while an excess of redeposition will prevent the bombarding particles from reaching the nonconductor to be analyzed.
		Because the relative redeposition is proportional to the discharge pressure, Milton and Hutton considered the pressure as (only) determining parameter in the building of the conducting layer.

		In relation to this the instructor mentioned that the F-16's ability to fly inverted is limited to approximately 25 seconds because, during inverted flight, gravity will draw most of the fuel away from the lines leading to the engine.
		Also, while discussing different electrical nonconductors/insulators, the instructor said that capton, the primary nonconductor used to insulate electrical wires in the F-16, is very explosive and is known to have caused several accidents in the past.

	Ivar Giaever Biography \| World of Scientific Discovery
		The nonconductor represents an "energy barrier" through which current can flow only if electrons that make up the current have more energy than does the barrier.
		Giaever studied the process of tunneling when two sheets of the same metal (aluminum) are joined by a nonconductor and when two unlike metals (aluminum and lead) are joined by a nonconductor.
		He found a linear relationship between current and voltage in the former instance, and a highly nonlinear relationship in the second.

	Static Control in Desiccator Cabinets
		A surface exhibiting an excess of electrons is charged negatively, and an electron-deficient surface is charged positively.
		Electrostatic charges are usually generated by friction between and/or separation of two dissimilar materials, at least one of which is a nonconductor or a poor conductor of electricity.
		The means by which these charges are removed depends on whether the charged object is a conductor or a nonconductor (insulator).
