Stimuli-responsive and tunable soft-matter systems are an advanced class of materials applicable for drug delivery. Liquid crystals (LCs) are promising candidates as multifunctional materials that can respond to temperature, light or magnetic field. Particularly, ordering and physical properties of thermoresponsive LCs depend predominantly on temperature as external trigger.

The use of the sonoluminescence spectroscopy for the determination of main components in concentrated aqueous solution of alkali metal halides is examined. In concentrated RCl solutions (R = Li, Na, K;  = 100-600 g · dm) the sonoluminescence intensity is inversely proportional to ultrasound frequency in the range from 2 Hz up to 5 Hz. In the CsCl case the inverse proportionality is disturbed at ultrasound frequencies higher than 3 MHz.
