Description

Application

• Application of adsorptive stripping voltammetry based on PbFE for the determination of trace aluminum released into the environment during the corrosion process: The study highlights the role of ammonia buffer solutions in environmental monitoring techniques, particularly in tracing metal ion activities affecting corrosion processes (Wasąg J, Grabarczyk M, 2021).


• Long-Term Generation of Longitudinal Spin Order Controlled by Ammonia Ligation Enables Rapid SABRE Hyperpolarized 2D NMR: Demonstrates advanced NMR techniques facilitated by ammonia buffer solutions, enhancing molecular imaging capabilities essential in pharmaceutical research (Vaneeckhaute E, De Ridder S, Tyburn JM, Kempf JG, Taulelle F, Martens JA, Breynaert E, 2021).
