Application


  • Investigation on specific heat capacity and thermal behavior of sodium hydroxyethyl sulfonate: This study presents a detailed analysis of the thermal behavior and specific heat capacity of sodium hydroxyethyl sulfonate, also known as 2-hydroxyethanesulfonic acid sodium salt (SHES) (H Hao, Y Zhang, X Chen, 2017).

  • Design and Mechanism of a Self‐Powered and Disintegration–Reorganization–Regeneration Power Supply with Cold Resistance: The research explores a novel power supply system using 2-hydroxyethanesulfonic acid sodium salt, focusing on its cold resistance characteristics (H Dai, Y Chen, W Dai, Z Hu, M Li, W Zhang, 2021).
