Dave, Don, Moira, me and the HECC

Research output: Contribution to conferencePaperpeer-review


Hydrogen Electrode Concn. Cells (HECCs) were originally developed at Oak Ridge National Lab. in the late 1960s and permit potentiometric measurements of unparalleled precision and accuracy well into the hydrothermal regime (to 300 C)​. Beginning in the early 1990s and continuing until the early 2000s, David Wesolowski, Donald Palmer, Moira Ridley and myself utilized the HECC to conduct the first ever systematic surface charge and ion adsorption expts. above 100C, on a variety of oxide surfaces, principally rutile, but also magnetite, nickel ferrite, and zirconia. This presentation will summarize those pioneering studies which were the forerunner to Dave conceiving and leading the Elec. Double Layer project, which began in about 2000.
