  • Influence of Carboxymethyl Cellulose as a Thickening Agent for Glauber′s Salt-Based Low Temperature PCM.: This study investigates the use of carboxymethyl cellulose to enhance the performance of Glauber′s salt (sodium sulfate decahydrate) as a phase change material (PCM) for low-temperature applications. The results indicate improved stability and efficiency, making it a viable option for thermal energy storage (Thakkar et al., 2024).

  • Nanoscale Stabilization Mechanism of Sodium Sulfate Decahydrate at Polyelectrolyte Interfaces.: The research explores the stabilization of sodium sulfate decahydrate at the nanoscale when interfaced with polyelectrolytes. This stabilization is crucial for enhancing the material′s applicability in energy storage systems and other industrial applications (Akamo et al., 2024).

  • The application of mirabilite in traditional Chinese medicine and its chemical constituents, processing methods, pharmacology, toxicology and clinical research.: An extensive review of the use of mirabilite (sodium sulfate decahydrate) in traditional Chinese medicine, focusing on its chemical properties, processing techniques, pharmacological effects, and clinical applications. The review underscores its historical and modern therapeutic relevance (Tao et al., 2023).

  • Stabilization of low-cost phase change materials for thermal energy storage applications.: This study addresses the stabilization methods for low-cost phase change materials, including sodium sulfate decahydrate, for use in thermal energy storage. It highlights the material′s potential for cost-effective and efficient energy solutions (Akamo et al., 2023).

In this work, we characterize physical hydrogels based on poly(vinyl alcohol), PVA, as intelligent biointerfaces for surface-mediated drug delivery. Specifically, we assemble microstructured (μS) surface adhered hydrogels via noncryogenic gelation of PVA, namely polymer coagulation using sodium sulfate (Na(2)SO(4)). We
