✦ Synopsis

Measurements of the surface acoustic wave (SAW) attenuation versus time have been performed in liquids with a relatively high evaporation rate (acetone, ethyl acetate, etc.). The linear dependence of the SA W attenuation versus time has been observed. The possibility of determining the 'unknown' molecular mass of the liquid from the SAW attenuation versus time dependence is presented. The special experimental arrangement allows an easy, quick and sensitive measurement of the evaporation rate.

We report on the investigation of surface acoustic wave (SAW) Ðelds by scanning acoustic force microscopy (SAFM), reaching submicron lateral resolution. The SAFM is based on a standard atomic force microscope and utilizes the non-linear force curve in the sense of a mechanical diode. The surface osc
