About the Cover: Cover image by Matej Kanduč and Marija Kanduč. When two neutral surfaces in an aqueous environment are brought to nanometer separation, they experience solvation forces arising from the properties of interfacial water. The graphic shows two extreme scenarios, where one polar surface (left) and one nonpolar surface (right) approach a hydrophilic support. The polar surface experiences a repulsive hydration force from the support. The nonpolar surface, usually accompanied by air bubbles, undergoes water cavitation, which leads to strong attractive forces and to adhesion to the support. The interaction properties of a pair of surfaces are determined by the sum of their respective water contact angles.
