The Adventures of Superman (radio) teenage copy boy. On "Superman" episodes featuring Batman, he played Bruce Wayne's butler, Alfred Pennyworth. Decades later, Beck portrayed Perry White, Clark Kent's boss, in Filmation's "The New Adventures of Superman" (1966–70), in addition to serving as the show's narrator. Just as Superman's true identity remained a secret, the identity of radio actor Collyer also remained a secret from 1940 until 1946, when the character of Superman was used in a promotional campaign for racial and religious tolerance and Collyer did a "Time" magazine interview about that campaign. Since there were no reruns at that time, the series often used
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. Butler–Volmer equation The Butler–Volmer equation (named after John Alfred Valentine Butler and Max Volmer), also known as Erdey-Grúz–Volmer
