Prof. Jerzy Sobkowski starts off this 31st volume of Modern Aspects of Electrochemistry with a far-ranging discussion of experimental results from the past 10 years of interfacial studies. It forms a good background for the two succeeding chapters. The second chapter is by S. U. M. Khan on quantum mechanical treatment of electrode processes. Dr. Khan's experience in this area is a good basis for this chapter, the contents of which will surprise some, but which as been well refereed. Molecular dynamic simulation is now a much-used technique in physical electrochemistry and in the third chapter Ilan Benjamin has written an account that brings together information from many recent publications, sometimes confirming earlier modeling approaches and sometimes breaking new territory. In Chapter 4, Akiko Aramata's experience in researching single crystals is put to good advantage in her authoritative article on under- tential deposition. Finally, in Chapter 5, the applied side of electrochemistry is served by Bech-Neilsen et al. in the review of recent techniques for automated measurement of corrosion. J. O'M.
