TL;DR: In this paper, the authors determined the rate of the catalytic rate in the PA growth reaction by Δ i/nFA = k c [anniline][PA] where n is the number of electrons transferred, F is the Faraday constant, A is the electrode area, and k c is the rate constant.

TL;DR: The SI unit of amount of substance, the mole, was introduced in this paper, and it is used to measure the ratio of two amounts of substance in an elementary entity, including molar mass, molar quantities in general, the Avogadro constant, the molar gas constant and the Faraday constant.
Abstract: The use of the term amount of substance of an elementary entity is expounded. Methods of measurement of the ratio of two amounts of substance are described. The SI unit of amount of substance, the mole, is introduced. Quantities involving amount of substance, including molar mass, molar quantities in general, the Avogadro constant, the molar gas constant, and the Faraday constant, are defined. An historical account is given of the notion of amount of substance and of the unit mole. Some personal views are advanced about the desirability of a new name for amount of substance and for derived quantities.

TL;DR: In this article, a two dimensional model is proposed for stripe domains in some ferromagnetic films, which includes the dependence of wall width on wall angle and thereby shows that variations in stripe domain spacing of more than an order of magnitude are possible.
Abstract: Stripe‐domain ferromagnetic films with high Faraday rotation and low optical absorption will rotate the angle of polarization of light transmitted through even‐numbered domains an angle φ = FT and through odd‐numbered domains an amount −φ, where F is the Faraday constant and T is the film thickness. The result of the differential rotation is that the film will act like a transmission diffraction grating. Since the orientation and spacing of the stripes may be altered by appropriate applied fields, the film may be used as a laser light deflector. A two dimensional model is proposed for stripe domains in some ferromagnetic films. This model differs from previous models (see Ref. 4–8) in that it includes the dependence of wall width on wall angle and thereby shows that variations in stripe‐domain spacing of more than an order‐of‐magnitude are possible. Variations of this amount were observed experimentally in a YIG platelet which was used as a stripe‐domain light deflector.
