โฆ Synopsis
supplemented by parallel and simultaneous morphological studies but they must be carried out whilst the deposition is in progress rather than after it was stopped, because of the necessity of measuring the rates of the moving entities, e.g., macrosteps, during growth. Only under these conditions can the mechanism of metal electrocrystallization be more fully understood.

Recent interest in the measurement and the interpretation of heat capacities of activation has led to more rigorous methods to detect temperature-varient activation parameters. One such method devised by Blandamer and co-workers was applied to the sucrose hydrolysis data of Moelwyn-Hughes and Leinin
