FINAL PROGRAM





SECOND INTERNATIONAL SYMPOSIUM ON

CONTACT ANGLE

WETTABILITY AND ADHESION

JUNE 21-23, 2000

ROBERT TREAT HOTEL

NEWARK, NJ

This symposium is the follow on to the one held in 1992 in honor of Professor Robert Good as part of the American Chemical Society meeting in San Francisco. This symposium will be concerned with both the fundamental and applied aspects of contact angle measurements. Issues such as the applicability and validity of various measurement techniques and the proper theoretical framework for the analysis of contact angle data are of prime concern. The primary focus of this symposium is to provide a forum for the discussion of cutting edge advancements in the field and to review and consolidate the accomplishments which have been achieved thus far.
