“…It is noted that transitions followed by sharp change of solution`s properties, specifically -optical density, could be induced by variety of external actions (electricity, electromagnetic emission of different wave-length, change of temperature, pressure, acidity, etc.). This variety of action might be modified and adjusted for information recording in heterogeneity environment [2][3][4] or in any distributed media connected not only in polymer solu-tions [5]. Generally, these transfers are connected with sharp change of macromolecules` solubility which is caused by change of hydrophobic-hydrophilic balance, stimulated by external actions [6].…”

It is demonstrated, for the first time,that well-known phase transitions induced by changes in temperature in solutions of polymers containing both hydrophilic and hydrophobic functional groups could be followed by noticeable hysteresis effects. A<br />well-known phase transitions accompanied by a sharp change in fluid properties, in particular its optical density can be induced by many external influences, including temperature changes occurring in the solutions of polymers containing both<br />hydrophilic and hydrophobic functional groups. Since intensification subsequent hydrophobic interactions, leading to loss of solubility of the polymer molecules, resulting, in particular, a significant increase in the turbidity of the medium and are accompanied by a pronounced hysteresis phenomena. Hysteresis phenomena in the processes of molecular-scale play an important theoretical and practical interest in linkage with the development of advanced nano-level technology. In particular, the issue of the development of molecular "trigger" switches, and other analog electronic systems, implemented on submolecular level was actively discussed. In fact, under the same physical conditions of the environment of macromolecules system can be in two different states, which resolves the issue of programming such molecules. State of these polymers depends on their way of formation and thermodynamic variables. Observed effect could be utilized directly for information recording into the structure on the basis of stimulus-sensitive macromolecular chains. In fact, it is a first step towards creating memory of quasi-biological elements.

“…-Reservoirs 3 and 4 are filled with warmed (T1) and cooled (T2) solutions of low-molecular electrolyte (for definiteness, sodium chloride will be considered below). In the case of the non-equal temperature of volumes (1) and (2), the system, Fig.1 is converted into an analog of thermocouple. Let us show, that such thermocouple may operate as desalination system too.…”

“…The methods are based on osmotic phenomena taking place in solutions of low-and high-molecular compounds. Regulation of local salt concentration due to contact of solution with strongly swelling polymer gel results in local variations of osmotic pressure [1] and amplification of circulation of the liquid in the counter; the effect may be used for cooling of solar panels, etc.…”

It is shown that it is possible to implement analog of a dialyzer based on sewed polymer networks, working on the basis of the temperature difference between two reservoirs containing low molecular weight salt. The result of such dialyzer using is enrichment of one those solutions by low molecular component and depletion of the other. It is shown that for providing the necessary temperature, it is possible to use energy of solar radiation.
