Theory and modeling of nanocrystalline-amorphous transition in liquids
12 Oct 2022
Abstract
Recently is was discovered in various applications that many physical and chemical properties of water change their temperature dependence between about $35$ and $60$ degrees Celsius. In particular, heat conductance, light absorption, and surface tension all change their temperature dependence. These drastic changes were associated with water gradually changing its mesoscopic structure: while at the higher temperatures water is a uniform media (amorphous state), at the temperatures below transition it consists of many nano-to-micro-scale clusters (crystalline state). This transition is similar to the second order phase transition. In the present paper we show that treating water with non-thermal plasma (adding plasma-created active compounds) can lower the temperature of the transition and thus cause a significant change in such physical quantities as surface tension, viscosity, freezing rate, and wettability and washability. We present analytical estimates of the transition temperature shift based on the Debye–Hückel theory. We discuss the produce-washing experiments that illustrate the predicted effects.
