  2. Graphene - Wikipedia

    en.wikipedia.org/wiki/Graphene

    Hydrogen cations, dissolved in molten lithium chloride, can be discharged on cathodically-polarized graphite rods, which then intercalate, peeling graphene sheets. The graphene nanosheets produced displayed a single-crystalline structure with a lateral size of several hundred nanometers and a high degree of crystallinity and thermal stability ...

  3. Tube (fluid conveyance) - Wikipedia

    en.wikipedia.org/wiki/Tube_(fluid_conveyance)

    A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch pipe will not actually measure 1 inch in either outside or inside diameter, whereas many types of tubing are ...

  4. Nanosheet - Wikipedia

    en.wikipedia.org/wiki/Nanosheet

    A nanosheet is a two-dimensional nanostructure with thickness in a scale ranging from 1 to 100 nm. [1] [2] [3] 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.

  5. Graphene morphology - Wikipedia

    en.wikipedia.org/wiki/Graphene_morphology

    A graphene morphology is any of the structures related to, and formed from, single sheets of graphene. 'Graphene' is typically used to refer to the crystalline monolayer of the naturally occurring material graphite. Due to quantum confinement of electrons within the material at these low dimensions, small differences in graphene morphology can ...

  6. Electronic properties of graphene - Wikipedia

    en.wikipedia.org/wiki/Electronic_properties_of...

    Scattering by graphene's acoustic phonons intrinsically limits room temperature mobility to 200 000 cm 2 ⋅V −1 ⋅s −1 at a carrier density of 10 12 cm −2, [12] [13] 10 × 10 6 times greater than copper. [14] The corresponding resistivity of graphene sheets would be 10 −6 Ω⋅cm.

  7. Single-layer materials - Wikipedia

    en.wikipedia.org/wiki/Single-layer_materials

    Graphene is a crystalline allotrope of carbon in the form of a nearly transparent (to visible light) one atom thick sheet. It is hundreds of times stronger than most steels by weight. [ 5 ] It has the highest known thermal and electrical conductivity, displaying current densities 1,000,000 times that of copper . [ 6 ]

  8. Bilayer graphene - Wikipedia

    en.wikipedia.org/wiki/Bilayer_graphene

    The bilayer graphene shows a specific surface area of 1628 m 2 /g, a pore size ranging from 2 to 7 nm and a total pore volume of 2.0 cm 3 /g. [ 30 ] Using bilayer graphene as cathode material for a lithium sulfur battery yielded reversible capacities of 1034 and 734 mA h/g at discharge rates of 5 and 10 C, respectively.

  9. Boron nitride nanosheet - Wikipedia

    en.wikipedia.org/wiki/Boron_nitride_nanosheet

    The air stability of graphene shows a clear thickness dependence: monolayer graphene is reactive to oxygen at 250 °C, strongly doped at 300 °C, and etched at 450 °C; in contrast, bulk graphite is not oxidized until 800 °C. [13] Atomically thin boron nitride has much better oxidation resistance than graphene.
