Chemistry Ferrari P Liggieri C Miller I S PCIS 3 3 D R O P S A N D B U B B L E S I N C O N TAC T The third volume in a series dedicated to colloids and interfaces, Drops and Bubbles in Contact with Solid Surfaces presents an up-to-date overview of the fundamentals and applications of drops and bubbles and their interaction W I T H S O L I D with solid surfaces. The chapters cover the theoretical and experimental aspects of wetting and wettability, liquid–solid interfacial properties, and spreading S U R FAC E S dynamics on different surfaces, including a special section on polymers. The book examines issues related to the interpretation of contact angle from nano to macro systems. Expert contributors discuss interesting peculiarities, such as the phenomena of super-spreading and super-hydrophobicity. They Edited by discuss specific solid surfaces—for example, reactions and wetting of liquid M. Ferrari, L. Liggieri & R. Miller metals at high temperatures—and the interaction between nano-bubbles at solid surfaces and nano-particles at liquid interfaces. The book also includes a chapter on electro-wetting. Given the range of topics covered in this volume, the state-of-the-art content is useful to readers looking for an introductory overview as well as those looking for in-depth exploration of material related to the interaction of fluids with solid surfaces. It is a valuable contribution to the field of characterization of solid surfaces and can be used as a working tool or to stimulate further study for researchers and students. Series Editors R.

WettingScience Wetting science, in its more classical definition, studies the way of interaction of a fluid with a solid surface, which determines the specific shape that liquids as- sumewhentheyaredepositedonasolidsubstrate.T.Youngin1805[1]statedthat a liquid drop placed on a solid surface assumes a geometrical shape that can be describedbyhisfamousformula(1),thatbecamethemilestoneofwettingstudies: cosθ =(γ −γ )/γ , (1) sv sl lv whereθ isthestaticcontactangle, γ andγ arethesolid–vaporandsolid–liquid sv sl surface energies and γ is the liquid surface tension (Fig. 1). The Young Equation lv (YE) therefore describes how, in a true equilibrium condition, the contact angle between a fluid and a solid depends only upon the intrinsic nature of the mate- rials engaged in the wetting experience. No dimension or gravity constraints are apparentlypresentinit.DuetoitsapparentsimplicityYEisstillconsideredasthe DropsandBubblesinContactwithSolidSurfaces © KoninklijkeBrillNV,Leiden,2012
