Opis

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).
