[Changes in dynamics of phase transitions in various liquids by recording of acoustic mechanical impedance of a drying drop].
A method of studying multicomponent liquids is proposed, which is based on recording the dynamics of the acoustomechanical impedance of a drop that dries up on the surface of a quartz resonator oscillating with an ultrasound frequency. The magnitude of the acoustomechanical impedance is an integral characteristic of the physical properties of the drop such as viscosity, composition, surface tension, moistening, and inner structure. Using liquids of different types as an example, it was shown that each liquid possesses its individual "portrait", which is determined by the phase transitions. The method can be used for the screening identification of liquids (determining the degree of consistency with the standards) in solving a number of scientific and practical problems, as well as in medicine.
