Beschreibung

Application

• Transparent sodium polytungstate polyoxometalate aquatic shields toward effective X-ray radiation protection: Alternative to lead glasses.: This study explores the development of transparent sodium polytungstate polyoxometalate-based shields for effective X-ray radiation protection. The research demonstrates that these aquatic shields can serve as a non-toxic alternative to traditional lead glasses, offering high transparency and efficient radiation attenuation. This makes them suitable for various applications in medical and industrial X-ray protection (Hashemi et al., 2022).


• Hybrid of sodium polytungstate polyoxometalate supported by the green substrate for photocatalytic degradation of auramine-O dye.: This paper investigates the photocatalytic properties of sodium polytungstate polyoxometalate supported on a green substrate for the degradation of auramine-O dye. The study highlights the efficiency of this hybrid material in environmental applications, particularly in wastewater treatment, by utilizing photocatalytic processes to break down harmful dyes (Mousavi et al., 2022).


• Bioinorganic Synthesis of Sodium Polytungstate/Polyoxometalate in Microbial Kombucha Media for Precise Detection of Doxorubicin.: This research presents a novel biosensor developed using sodium polytungstate/polyoxometalate synthesized in a microbial kombucha medium. The biosensor shows high sensitivity and precision in detecting doxorubicin, a chemotherapeutic drug, in biological fluids. This innovative approach enhances the biosensor′s performance, making it suitable for clinical applications in drug monitoring and pharmacokinetics studies (Mousavi et al., 2022).
