In Alfred's first appearance, he was overweight and clean-shaven; however, when the 1943 "Batman" serial was released, William Austin, the actor who played Alfred, was trim and sported a thin moustache. DC editors wanted the comic Alfred to resemble his cinematic counterpart, so in "Detective Comics" #83 (January 1944), Alfred vacationed at a health resort, where he slimmed down and grew a mustache.

Butler–Volmer equation the surface is equal to that in the bulk. There are two limiting cases of the Butler–Volmer equation: where formula_21 and formula_22 are constants (for a given reaction and temperature) and are called the Tafel equation constants. The theoretical values of the Tafel equation constants are different for the cathodic and anodic processes. However, the Tafel slope formula_22 can be defined as: where formula_25 is the faradaic current, expressed as formula_26, being formula_27 and formula_28 the cathodic and anodic partial currents, respectively.
