This volume contains papers originally presented at the Symposium on Acid—Base Interactions: Relevance to Adhesion Science and Technology, held on the occassion of the 75th birthday of Professor Frederick M. Fowkes, as a part of the 64th Colloid and Surface Science Symposium at Lehigh University, June 18-20, 1990.

From the Preface: “...When the idea of organizing a symposium in honor of Dr. Fowkes was conceived, the question arose as to what should be the theme of the symposium as he had made significant contributions dealing with the many ramifications of interfacial science and technology. However, after some deliberation, it became clear that a most apposite topic would be `acid—base and adhesion', as in the last several years the leitmotif of Dr. Fowkes's research has been in the realm of acid—base interactions...[H]e had been a key protagonist of the concepts of acid—base interactions, had done a lot to popularize such concepts, and had shown how understanding of such interactions could be parlayed to control adhesion behavior in a given situation...”

Target Audience: Academic or industrial scientists and technologists concerned with acid—base interactions and their effect on adhesion.
