Dear Bob,
thanks for your note. Here is the short description of our work on "dewetting":
One is our early work (Luzar et al, JCP 1987) that interpreted hydrophobic interaction in terms of model water depletion between inert solute surfaces. This is the first paper ever that shows spontaneous water evaporation from hydrophobic confinement. It also gives the statistical mechanical determination of density profile in the gap based on graphical expansion of density. Ten years later we have another important contribution (Lum and Luzar, PRE 2007): this is the first paper in the literature that derives the Kelvin eq. for finite plates. Note that in 2003 Bruce (Berne) uses the ANALOGOUS equation to study the dewetting-induced collapse of ellipsoidal hydrophobic particles. Further, our PRE 97 paper is also the first one to point out, that for specific conditions of all the calculations in the literature (at that time up to 1997), simulations captured spontaneous evaporation at distances consistent with the Kelvin eq. for finite objects. Subsequent simulations (1997-present) conform to our observation. Finally the PRE 97 paper is the first to point to kinetic aspects of hydrophobic interaction, and to the importance of chemical inhomogeneity characteristic for real systems ( ref. 20 in that paper).
The coarse-graining approach in my PRE07 paper has been taken to another level- to explicit calculation of activation barriers in our papers in JCP 2000, and to the molecular level in PRL 2003.
What follows is my activation free energy scaling of capillary evaporation paper in JPCB 2004, that concerns both scalings, with intersurface separation, and with contact angle, and the effect of dissolved gases on dewetting in JPCB 2005 and Langmuir 2008. To the best of our knowledge we were the first and currently still remain one of the very few groups studying the solubility of gases in hydrophobic confinement on a molecular level, including the pressure effects, despite potential influence of gases on the hydrophobic effect. I attach the complete list of references for your convenience.

I would be very interested to receive your future work on "dewettting" in biological systems. Please let me know if you need the pdf's of the papers listed above (I did not want to clutter your mbox).
Cheers, Alenka

Sadly you are not the only one whose work I forgot as I wrote the discussion, etc. Please forgive me. Please send me the papers I should quote and I will put them in the next paper and in a arXiv article I plan to write.
