General description

Sodium bromide (NaBr) is an inorganic salt. It is an inexpensive source of bromide anion. It is used as a nucleophilic catalyst in organic synthesis. Additionally, NaBr is a useful electrolyte in electrochemical oxidations.

Application


  • Sensitive and Low-Noise Perovskite Nanocrystal-Organic Bulk Heterostructure X-ray Detectors Enabled by Sodium Bromide-Assisted In Situ Reparation: This research underscores the role of sodium bromide in enhancing the fabrication of perovskite nanocrystals for advanced X-ray detection technologies, illustrating its utility in high-precision imaging applications critical for both medical and industrial use (Li Y, Fang Y, 2024).

  • Surface-Modified Carboxylated Cellulose Nanofiber Hydrogels for Prolonged Release of Polyhexamethylene Biguanide Hydrochloride (PHMB) for Antimicrobial Applications: Demonstrates the effectiveness of sodium bromide in modifying cellulose nanofibers for use in sustained drug release systems, highlighting its importance in the development of antimicrobial materials (O-Chongpian P, Jantrawut P, 2023).

  • Unravelling Alkali-Metal-Assisted Domain Distribution of Quasi-2D Perovskites for Cascade Energy Transfer toward Efficient Blue Light-Emitting Diodes: Details the utilization of sodium bromide in the synthesis of quasi-2D perovskites, paving the way for improvements in blue light-emitting diode (LED) technology which is crucial for display and lighting solutions (Cai W, Yip HL, 2022).

  • Chronic sodium bromide treatment relieves autistic-like behavioral deficits in three mouse models of autism: Highlights the potential therapeutic applications of sodium bromide in neuropsychiatric disorders, providing insights into its efficacy in alleviating symptoms of autism within experimental settings (Derieux C, Becker JAJ, 2022).

  • Development of Flexible Plasticized Ion Conducting Polymer Blend Electrolytes Based on Polyvinyl Alcohol (PVA): Chitosan (CS) with High Ion Transport Parameters Close to Gel Based Electrolytes: Showcases the role of sodium bromide in the development of high-performance polymer electrolytes for energy storage applications, demonstrating its impact on enhancing ion transport properties (Sadiq NM, Kadir MFZ, 2022).
