JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Overview

Course objectives:

• 1. This course is primarily intended to expose the students to a highly interdisciplinary subject.
• 2. This would emphasize on the classification, synthesis and applications of Nano materials. Course outcomes: After completing this course, the student should be able to:
• 1. Indicate the differences between nanomaterials and conventional materials
• 2. Indicate how specific synthesis techniques can result in nanomaterials
• 3. Give examples of specific nanomaterials and explain the scientific reasons for the properties displayed by them
• 4. Describe how specific characterization techniques can be used to analyze nanomaterials
