Non - Metallic Materials

There have been radical development in the study of non – metallic materials over past two decades – think of Li and Na ion rechargeable batteries, graphene, carbon nano-tubes, conducting polymers, sensing materials for air quality monitoring etc. The course aims students to understand the structure – property relationship in a wide spectrum of non – metallic materials. The course is divided into 12 weekly modules containing 5 lectures in each module with 30 min duration. Modules that will be taught sequentially are named as follows: (i) Polymer materials, (ii) Defects, and reaction kinetics of non – metallic materials, carbonaceous materials (iii) Diffusion, phase transformation in non – metallic materials, glass and glass ceramics, (iv) Mechanical properties of non – metallic and composite materials, (v) Electrical, magnetic and thermal properties of non – metallic materials, (vi) Optical and electrochemical properties of non-metallic materials, (vii) Processing of non – metallic materials, sintering and microstructure development, (viii)Thin film growth and fabrication of devices, (ix) Characterization of structure, composition, and microstructure of non – metallic materials, (x) Measurement of the mechanical, electrical, thermal, magnetic, and optical properties of non – metallic materials, (xi) Corrosion and degradation of non – metallic materials, and (xii) Economic, environmental and societal issues. Each module lectures is self-contained to encourage student understanding and reinforce key concepts. Carefully designed problem set will help students to grasp the underlying concepts taught in the course.
