Course objectives
This course offers three chapters oriented towards: 1. Classical and modern colloid chemistry focusing on ●Definition, classification and critical parameters, ●Aggregation and coagulation stability, ●Thermodynamics and kinetics of colloid formation; ●Nucleation and Growth models in liquid media, ●Optical properties of nanocolloidal semiconductors and metals along with an ●Overview of analytical methods employed in nanoparticle research. 2. Sol-Gel chemistry focusing on ●Molecular Precursors and their preparations, ●Synthesis strategies of oxide based ceramics, glasses and organosiloxane hybrids, ●Film formation processes and ●Photolithographic patterning methods; 3. Wet chemical nanoparticle synthesis focusing on ●binary and ternary metal oxides (M: Zn, Ti, W, Si, Fe etc), ●metal chalcogenides and oxynitrides (M: Zn, Cd, In, Ga, Ge, Ti etc; Anions: S, Se, Te, OxNy) and ●metallic/bimetallic nanocolloids (Au, Ag, Cu, Pd, Pt etc)
