Potential graphene applications include lightweight, thin, and flexible electric/photonics circuits, solar cells, and various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials, and favoured by massive cost decreases in graphene production.

The electronic properties of graphene are significantly influenced by the supporting substrate. [59] [60] The Si(100)/H surface does not perturb graphene's electronic properties, whereas the interaction between it and the clean Si(100) surface changes its electronic states significantly. This effect results from the covalent bonding between C ...
Graphene is the only form of carbon (or solid material) in which every atom is available for chemical reaction from two sides (due to the 2D structure). Atoms at the edges of a graphene sheet have special chemical reactivity. Graphene has the highest ratio of edge atoms of any allotrope. Defects within a sheet increase its chemical reactivity ...
Both graphene and diamond exhibit high Young's modulus, low density, low friction, exceedingly low mechanical dissipation, [17] and large surface area. [ 19 ] [ 20 ] The low friction of CNTs, allow practically frictionless bearings and has thus been a huge motivation towards practical applications of CNTs as constitutive elements in NEMS, such ...
Twistronics (from twist and electronics) is the study of how the angle (the twist) between layers of two-dimensional materials can change their electrical properties. [ 1 ] [ 2 ] Materials such as bilayer graphene have been shown to have vastly different electronic behavior, ranging from non-conductive to superconductive , that depends ...
A typical example of a nanosheet is graphene, the thinnest two-dimensional material (0.34 nm) in the world. [4] It consists of a single layer of carbon atoms with hexagonal lattices . Examples and applications
Graphene batteries being tested in experimental electric cars have promised capacities 4 times greater than current batteries with the cost being 77% lower. [26] Additionally, graphene batteries provide stable life cycles of up to 250,000 cycles, [27] which would allow electric vehicles and long-term products a reliable energy source for decades.
Graphene quantum dots (GQDs) are graphene nanoparticles with a size less than 100 nm. [1] Due to their exceptional properties such as low toxicity, stable photoluminescence , chemical stability and pronounced quantum confinement effect, GQDs are considered as a novel material for biological, opto-electronics, energy and environmental applications.
