Application
- Synthesis and characterization of Anderson-Evans type polyoxometalates, antibacterial properties.: This research focuses on the synthesis and characterization of Anderson-Evans type polyoxometalates, evaluating their antibacterial properties. Sodium tungstate dihydrate is used in the synthesis process to form these polyoxometalates. (Avci Özbek, 2023).
- Nitric oxide modulates folate-mediated one-carbon metabolism and mitochondrial energy levels of peaches during cold storage.: This study explores the role of nitric oxide in modulating folate-mediated one-carbon metabolism and mitochondrial energy levels in peaches during cold storage. Sodium tungstate dihydrate is used as an analytical reagent in the experiments. (Yang et al., 2023).
- Facile Bottom-up Preparation of WS(2)-Based Water-Soluble Quantum Dots as Luminescent Probes for Hydrogen Peroxide and Glucose.: Details a novel method for preparing WS(2)-based water-soluble quantum dots used as luminescent probes for detecting hydrogen peroxide and glucose. Sodium tungstate dihydrate is used in the preparation of these quantum dots. (Hang et al., 2019).
