Metal ores and their concentration; extraction of crude metal from concentrated ores: thermodynamic (iron, copper, zinc) and electrochemical (aluminium) principles of metallurgy; cyanide process (silver and gold); refining. Principles of Qualitative Analysis Groups I to V (only Ag+ , Hg2+, Cu2+...
For example, mixing solutions of silver nitrate and sodium fluoride will yield a solution containing Ag+, NO–, Na+, and F–ions. Aside from the two ionic compounds originally present in the solutions, AgNO3and NaF, two additional ionic compounds may be derived from this collection of ions: ...

Silver nitrate and sodium borohydride were employed as a metal precursor and reducing agent respectively. On the other hand, chitosan and gelatin were added as a polymeric matrix and stabilizer. The antibacterial activity of different sizes of silver nanoparticles was investigated against Gram-positive ...
The Ag MVV Auger region of the XPS spectra (Figure 4b) reveals that some of the silver in the coating is present in its reduced form on coatings that have been treated with higher silver nitrate concentrations (0.01 and 0.1 M). This emergence of metallic silver is not easily explained...

In simulated oral disintegration tests, almost 100% of epigallocatechin gallate (EGCG) dissolved within 4 min from the ESF. In summary, the incorporation of SAFs into ESF improved their mechanical strength, hydrophobicity, and enabled them to exhibit antibacterial properties, making them promising ...
