Application


  • Estimating the nonideality of eutectic systems containing thermally unstable substances.: The paper explores the use of Tetramethylammonium chloride in studying the non-ideal behavior of eutectic mixtures, contributing to better thermal management in material science and engineering (Minceva M et al., 2023).

  • Natural deep eutectic solvents as thermostabilizer for Humicola insolens cutinase.: This study examines how Tetramethylammonium chloride-based eutectic solvents can stabilize enzymes, enhancing their practical applications in biotechnological processes (Sisti L et al., 2023).
