Abstract
Response to comment on “Point of zero charge of a corundum-water interface probed with optical second harmonic generation (SHG) and atomic force microscopy (AFM): new approaches to oxide surface charge”
Highlights
The purpose of this response is to address several misrepresentations of Stack et al (2001) and its intent in the preceding Comment
Dr Kosmulski does a particular disservice with the statement “. . . the discrepancy between the results of Stack et al (2001) and those published by others indicates certain limitations of the Second Harmonic Generation (SHG) method as the tool to establish the pristine PZC of alumina.”
Dr Kosmulski’s primary scientific objections have nothing to do with the second harmonic generation (SHG) technique per se but rather with the wet-chemical system to which SHG was applied
Summary
At issue is our observed point of zero salt effect (p.z.s.e.) of a single crystal face of corundum using optical second harmonic generation (SHG) at a pH (ϳ5) much lower than the accepted value (in the 8 –9 range) of the pristine p.z.c. of alumina powders. Dr Kosmulski’s main claim is that our anomalous observation is the result of surface contamination.
