The evaporation of a liquid droplet on a solid substrate is a ubiquitous physical phenomenon. In a vast variety of real-life situations spherical drops are the exception rather than the rule, yet the intricacy of the physical mechanisms involved has constrained the study of this problem to spherical configurations.

The evaporation of a sessile droplet is a practically important one which is currently the subject of intense research activity both because of the wide range of practical applications (such as, for example, ink-jet printing and industrial cooling) in which it arises and the fascinating and complex behaviour is can exhibit.

Studies of sessile droplets provide a natural framework for modeling dynamic contact lines. We present several recent results on droplet behavior on heated substrates under the conditions when the effects of both wetting and evaporation are important. For liquids which are aqueous solutions, we investigate how the formation of electrical double layers near the interfaces affects droplet spreading and evaporation. Apparent contact angle is found as a function of both heating and ion concentration in the liquid.
