Another form of metallizing nonconductor substrates is the dynamical chemical plating (DCP) method, (17) which is a wet deposition technique that has been shown to be a good alternative for producing deposits of single metals such as Cu, Ni, and Ag.
To prove that he can let [nabla] x A = 0, he takes the divergence of (101) and assumes the medium is now a nonconductor so that a = 0, to get
Molar conductivity in DMSO shows nonconductor behaviour [17] (14 [[ohm].sup.-1] [cm.sup.-1] [mol.sup.-1]) for 2, 17 [[ohm].sup.-1] [cm.sup.-1] [mol.sup.-1] for 3,10 [[ohm].sup.-1] [cm.sup.-1] [mol.sup.-1] for 5 and 2: 1 electrolyte (145 [[ohm].sup.-1] [cm.sup.-1] [mol.sup.-1]) for 1, and (150 [[ohm].sup.-1] [cm.sup.-1] [mol.sup.-1]) for 4.
Metal may get hot, but it will not explode like a composite or nonconductor. If the mast is nonconductive, such as composite or wood, then a separate metallic conductor must be run up to the air terminal.
Representative responses included having something "to wipe my feet on" and "to avoid the cold floor." Five other reasons were given, including that a "rubber" mat was used because it "is a nonconductor of electricity." Table 1 shows the frequency of the participants' comments in each category.
Corona discharge and electrostatic induction can separate a mixture of conductor and nonconductor (metal/insulator), whereas the triboelectrostatic method has an advantage of separating different types of materials [23, 24].
As quoted by the court, the asserted utility of the claimed compound was as "a nonconductor of electricity," as a "reducing agent," and "useful in operations where silicon and aluminum are now employed." (58) The Court of Appeals of the District of Columbia found these assertions to "show utility sufficient to support a patent," and quoted with approval from the decision of the Examiners-in-Chief:
At zero frequency (dc), the current is zero since there is a nonconductor between the plates.

It does not light up when the material is a nonconductor or insulator.
