Sol-Gel Process: Glass Machining and Synthesis of Silica Nanoparticles

This lecture covers the sol-gel process, a method for forming a 3D poly-network of metal oxide from liquid to solid phase. It explains the stability of dispersions, the synthesis of silica nanoparticles, and the control parameters for network formation. The instructor discusses the applications of SiO₂ and TiO₂ nanoparticles, glass machining, and the preparation of borosilicate sol and nanoparticles. The lecture also delves into in situ glass modification, polymer microfabrication, and the properties of different types of polymers.
