The lecture will present the results of a series of studies on droplets evaporation and wetting. It will aim to elucidate the effects of substrate thermal properties as well as atmosphere nature and atmospheric conditions. The presentation will introduce the results also reveal some hydrothermal instabilities and patterns. The evaporation of complex fluids drops such as nanofluids and polymers will be introduced. Theoretical studies on evaporating droplets lifetimes and effect of wettability will be discussed. Following these fundamental aspects of droplets evaporation the lecture will introduce some concepts on the development of a Leidenfrost engine driven by droplets levitating on hot substrates.
