**Fundamentals of Graphene**

in Chapter 7. Chapter 8 emphasizes on heteroatom-doped graphene-based hybrid materials for hydrogen energy conversion. Chapter 9 talks about porous graphene materials for ener‐ gy storage and conversion applications. Defects in graphene and its derivatives have been described in Chapter 10. Chapter 11 deals with plasmonic excitations in graphene for tunea‐ ble terahertz/infrared metamaterials and finally Chapter 12 reports graphene-based materi‐
