Application
- Sulfur-Containing Radical Anions Formed by Photolysis of Thiosulfate: Quantum-Chemical Analysis.: This study explores the formation of sulfur-containing radical anions through the photolysis of thiosulfate, employing quantum-chemical analysis to understand their properties and behavior. The research provides insights into the photochemical processes and potential applications in analytical chemistry (Fedunov et al., 2023) (Fedunov et al., 2023).
- Interactions Between Calcium Hypochlorite and Irrigants Commonly Used in Endodontic Practice: A Chemical Analysis.: This paper investigates the chemical interactions between calcium hypochlorite and common endodontic irrigants, including sodium thiosulfate. The study highlights the analytical methods used to understand these interactions and their implications for endodontic treatments (de Pellegrin et al., 2023) (de Pellegrin et al., 2023).
- Identification of the Toxic Constituents of Sediments in a Brazilian Subtropical Estuary.: This research identifies toxic constituents in sediments of a Brazilian estuary, using analytical techniques to measure the presence of harmful substances, including sodium thiosulfate as a detoxifying agent. The findings contribute to environmental monitoring and pollution control (Poleza et al., 2014) (Poleza et al., 2014).
- Sustainable Synthesis of Cadmium Sulfide, with Applicability in Photocatalysis, Hydrogen Production, and as an Antibacterial Agent, Using Two Mechanochemical Protocols.: Focuses on the sustainable synthesis of cadmium sulfide, employing sodium thiosulfate in the mechanochemical synthesis process. Applications include photocatalysis, hydrogen production, and antibacterial treatments. (Shalabayev et al., 2022).
