In this book chapter we focus on the modification of carbon materials with sp 2 hybridization (graphite and graphene) by using aryl diazonium salts. The on-surface chemistry of diazonium salts on model substrates is explored with a focus on the attempts that have been done to improve the ...

Most substances with giant covalent structure do not have van der Waals’ forces. However if the giant covalent structure consists of LAYER structure there are van der Waals’ forces beeen the layers of atoms. Graphite is typical example of giant covalent structure with layer structure...
Graphite and diamonds are made up of carbon atoms. Graphite, however, is soft and can be used to write with while diamonds are the hardest substance known to man and are the only substances that can be used to cut other diamonds. What is the main rea...

Structures and Properties of Solids:After studying ionic and metallic crystals in grade 11, we will examine the properties of covalent crystals in grade 12. Molecular Crystals:Molecular solids can have varying shapes depending on the substance, and they can get very complicated. However, the ...
The existence of the resulting interlayer covalent-like bonding is corroborated by electronic structure calculations and crystal orbital overlap population (COOP) analyses. In NGP-based graphite with the optimal doping level, the NGP layers are uniformly stacked and the 3D bulk exhibits metallic ...
