Nature and Properties of Materials: An Introductory Course

Nature and Properties of Materials: An Introductory Course. Instructor: Prof. Ashish Garg, Department of Materials Science and Engineering, IIT Kanpur. The course is first part of the broader course on Introduction to Nature of materials and would be suitable for undergraduate and postgraduate students of every branch of science and engineering. This course will focus on essentials of crystallography, crystal structures of different classes of materials, structure determination and defects in materials. (from nptel.ac.in)
