First published in 1996. ADHESION INTERNATIONAL 1993 is a volume of the Proceedings of the 16th Annual Meeting of The Adhesion Society, Inc. Williamsburg, Virginia, USA February 21-26,1993. This meeting featured an International Symposium on The Interphase. Interphases are extremely important in many areas of technology. They are formed when dissimilar materials are joined and they control the properties of adhesive joints, composites, coatings, and microelectronics devices. Considering the importance and scope of phenomena associated with the interphase, it was appropriate to convene such a symposium at the meeting.
