the ions are positively charged sodium ions and negatively charged chlorine atoms that form when sodium chloride is dissolved in water. The two metal objects are called electrodes. The electrodes and electrolyte choices make a difference in how well the electroplating...
The analysis of changes in the number of papers on GMF-related topics in the WoS and SCOPUS helped us to determine the degree of interest in the topic. However, we did not limit ourselves just to these two databases, but considered many other publications on the GMF and its impact on the...
Particle attraction and association are more effective in a saline solution rather than dilute solutions (freshwater) (Dao et al., 2020; Wu and Adachi, 2018). van der Waals attractive forces that operate between the atoms of particles can also cause particle association in saline medium. The ...
