Application
- Improved Anti-Vulcanization and Bonding Performance of a Silver Alloy Bonding Wire by a Cathodic Passivation Treatment with Palladium: This study highlights the application of ammonium sulfide solution in enhancing the anti-vulcanization and bonding properties of silver alloy bonding wires used in electronic devices. The cathodic passivation treatment using ammonium sulfide offers significant improvements in the durability and performance of materials, which is pivotal in material science and industrial manufacturing (Yang et al., 2022).
- The roles and applications of chaotropes and kosmotropes in industrial fermentation processes: Ammonium sulfide, utilized as a chaotrope, plays a crucial role in stabilizing enzymes and proteins during fermentation processes. This application is particularly important in biotechnological and pharmaceutical industries, where enzyme stability is critical to the efficiency of bioprocesses (Timson, 2020).
- Cobalt iontophoresis techniques for tracing afferent and efferent connections in the vertebrate CNS: While primarily focused on cobalt iontophoresis, this research outlines the potential utility of ammonium sulfide in similar neuroscientific applications. Ammonium sulfide can be used for tracing neural connections due to its effective ion transport properties, providing valuable insights into neural pathway studies (Fuller and Prior, 1975).
