Preparation And Characterization Of Silver Nanoparticles
That slow the transformation of silver ions into silver by the reducing agent. We obtain silver colloids of small sizes and a narrow distribution using only a small amount of protective agent while maintaining high conversion rates at reasonable silver concentrations at the same time. ...

Point Of Zero Charge - Wikipedia
The point of zero charge (pzc), in physical chemistry, is a concept relating to the phenomenon of adsorption, and it describes the condition when the electrical charge density on a surface is zero. It is usually determined in relation to an electrolyte's pH, and the pzc value is assigned to a given substrate or colloidal particle. ... Read Article
