Lecture
This lecture covers the structure of materials, focusing on metals, ceramics, and polymers. It discusses the arrangement of atoms in metals, the different structures of alloys, the crystallographic structures of ceramics, and the characteristics of organic materials. The lecture also explains the concepts of coordination, interstitial sites, defects in crystals, and the classification of polymers. Additionally, it explores the properties of thermoplastics, elastomers, and thermosetting polymers, providing examples of high-tech ceramics and their applications.
