Preface

The present volume constitutes Volume 3 in the ongoing series Advances in Contact Angle, Wettability and Adhesion which was conceived with the intent to provide periodic updates on the research activity and salient developments in the fascinating arena of Contact Angle, Wettability and Adhesion.

The provenance and intriguing historical evolution of contact angle/wettability was provided in the Preface to the premier volume. Contact angle study has been accorded glamour as pointed out in the Preface to Volume 2 that 5 Nobel Laureates had evinced interest in the study of contact angle/ wettability phenomena directly or indirectly. Prof. Pierre-Gilles de Gennes, in particular, led quite a hefty research program in the broad realm of wettability and provided many fundamental insights apropos of wetting phenomena.

In the Preface to the current Volume, I would like to draw attention of the readers to three interesting topics. First, in the June 1, 2015 Issue of the Chemical & Engineering News (C&EN of the American Chemical Society) a very illuminating and thought-provoking write-up entitled “‘Sleeping Beauties’ Wake Up” was published which referred to studies of 15 ‘sleeping beauties’ and seven of these were published in chemistry journals. Out of these 7 it is very pleasing to note that two were devoted to the study of wetting. The papers (which are very familiar today to every researcher in the field of wetting) by A.B.D. Cassie and S. Baxter (1944) and R.N. Wenzel(1936) had their “Awakening” only in 2002 and 2003, respectively. Today, these papers are routinely cited in articles dealing with wetting.

Second, I would like to point out that the contact angle has been dubbed as the poor man’s (or poor woman’s) surface analysis technique, as it does not require sumptuous equipment and contact angle measurements can be made using a modestly priced setup called goniometer with a small footprint. Carl Clegg (Rame-Hart Instruments Co.) in his December 2010 Newsletter has listed 50 things one can do with a goniometer. Here, the following eclectic list of interesting, technologically important and exotic applications of contact angle should suffice to underscore the ubiquity of
