2. Graphene - Wikipedia

   en.wikipedia.org/wiki/Graphene

   In addition, it is known that when single-layer graphene is supported on an amorphous material, the thermal conductivity is reduced to about 500 – 600 W⋅m −1 ⋅K −1 at room temperature as a result of scattering of graphene lattice waves by the substrate, [172] [173] and can be even lower for few-layer graphene encased in amorphous ...

3. Graphene oxide paper - Wikipedia

   en.wikipedia.org/wiki/Graphene_oxide_paper

   Graphene oxide paper or graphite oxide paper is a material fabricated from graphite oxide. Micrometer thick films of graphene oxide paper are also named as graphite oxide membranes (in the 1960s) or (more recently) graphene oxide membranes. The membranes are typically obtained by slow evaporation of graphene oxide solution or by the filtration ...

4. Nanosheet - Wikipedia

   Nanosheets can also be prepared at room temperature. For instance, hexagonal PbO (lead oxide)) nanosheets were synthesized using gold nanoparticles as seeds under room temperature. [3] The size of the PbO nanosheet can be tuned by gold NPs and Pb 2+ concentration in the growth solution. No organic surfactants were employed in the synthesis process.

5. Graphene foam - Wikipedia

   en.wikipedia.org/wiki/Graphene_foam

   Schematic of the synthesis of graphene foam using a Ni template (top) and photographs of the products (bottom) Electron micrographs of the graphene foam prepared using a Ni template. Graphene foam is a solid, open-cell foam made of single-layer sheets of graphene. [1] [2] It is a candidate substrate for the electrode of lithium-ion batteries.

6. Aerographene - Wikipedia

   en.wikipedia.org/wiki/Aerographene

   The stiffness and compressibility of graphene aerogels can be attributed in part to the strong sp 2 bonding of graphene and the π-π interaction between carbon sheets. In graphene aerogels, the π-π interaction can greatly enhance stiffness due to the highly curved and folded regions of graphene as observed through transmission electron ...

7. Electronic properties of graphene - Wikipedia

   The graphene sheet thus displays a semimetallic (or zero-gap semiconductor) character. Two of the six Dirac points are independent, while the rest are equivalent by symmetry. In the vicinity of the K-points the energy depends linearly on the wave vector, similar to a relativistic particle.
