Beschreibung

Anwendung

Ethanol was used as dispersion medium for already prepared silver nanoparticles.
It may be used in the following studies:

• Hydrothermal synthesis of single crystal ZnO nanorod.
• Synthesis of N-(N′dodecylcarboxamidomethyl)N,N,dimethyl ammonio propane sulfonates.
• As solvent for cytofluorimetric analysis.
• Preparation of TiO₂ colloid (particle size = 20nm).
