Material Science Concepts and Applications

The video explores the field of material science, emphasizing how scientists can alter or create materials with desired properties. It reviews basic concepts of materials and their properties, using diamonds as a case study to illustrate the difference between natural and lab-grown diamonds. The video explains the high pressure high temperature (HPHT) process used to create lab-grown diamonds and discusses the potential for future innovations in material science.
