For the first time, previously unknown multiple reaction stages have been identified during the reduction of silver ions in the high-temperature polyol process of synthesizing silver nanowires. New in situ potentiometric silver ion measurements clear

We have found that the thermal decomposition of [Ag(O2CnH2n–1)]2, where n = 14, 16, 18, and 22, produces the ordered 3D nanostructure (supracrystals) directly during the chemical reaction, which makes it possible to obtain self-assembled structures

Clusters of silver nanoparticles are generated by the thermally initiated reduction of silver carboxylates (long-chain fatty acids) in the thin polymer films. The size, shape, and aggregation of these nanoparticles are affected by the reduction react

The reaction of 5-methyl-2-mercaptobenzimidazole (5MBI) with silver ions in organic solvents form widely varying macrostructured or polymeric structures, depending on the anion type. In the case of carboxylate anions, the reaction of 5MBI with [Ag(O

Silver carboxylates can be made by the reaction of silver nitrate and the corresponding sodium carboxylates. The length of the alkyl chain has a significant impact on the product behavior. In this study, 18, 20, and 22 carbon chains (stearate, arachi
