Melting temperature hidden behind liquid−liquid phasetransition in glycerolStarzonek, Szymon (Avtor) Kalabiński, Jakub (Avtor) Drozd-Rzoska, Aleksandra (Avtor) Rzoska, Sylwester (Avtor) Iglič, Aleš (Avtor) glycerolphase transitionmeltingcritical fluctuationsLiquid−liquid phase transitions play a pivotal role in various scientific disciplines andtechnological applications, ranging from biology to materials science and geophysics. Understanding thebehavior of materials undergoing these transitions provides valuable insights into complex systems and theirdynamic properties. This review explores the implications of liquid−liquid phase transitions, particularlyfocusing on the transition between low-density liquid (LDL) and high-density liquid (HDL) phases. Weinvestigate the thermodynamic, structural, and mechanistic aspects of these transitions, emphasizing theirrelevance in diverse fields. The creation of dynamic heterogeneities and critical fluctuations during liquid−liquid phase transitions is discussed, highlighting their role in shaping the phase behavior and dynamics ofcomplex fluids. Experimental observations, including the use of dielectric spectroscopy and nonlinearmethods, shed light on the intricate nature of these transitions. Our findings suggest a connection between liquid−liquid phasetransitions and critical phenomena, with implications for understanding the supercooled state and phase behavior of hydrogen-bonded liquids such as glycerol. Overall, this review underscores the importance of interdisciplinary approaches in unraveling thecomplexities of liquid−liquid phase behavior and addressing fundamental questions.20252025-02-27 10:49:10Članek v reviji167546sl
