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.

Butler–Volmer equation Butler–Volmer equation The Butler–Volmer equation (named after John Alfred Valentine Butler and Max Volmer), also known as Erdey-Grúz–Volmer equation, is one of the most fundamental relationships in electrochemical kinetics. It describes how the electrical current on an electrode depends on the electrode potential, considering that both a cathodic and an anodic reaction occur on the same electrode: or in a more compact form: where: The right hand figure shows plots valid for formula_15. The previous form of Butler–Volmer equation is valid when the electrode reaction is controlled by electrical charge transfer at the electrode (and not by the mass transfer
