Is graphene a conductor?
It is a very good conductor.
What are the disadvantages of graphene?
There are a few issues associated with graphene that are preventing its commercialisation. The main issue at present is still the production methods for it. At present, there is no good general synthesis method that produces graphene quickly, precisely and in large enough quantities. Until this is overcome, we will not be seeing graphene on the mass-market. Issues surrounding biocompatibility and cytotoxicity are still to be fully addressed with different studies contradicting each other. There are also issues with the electrical properties of graphene that need to be fully sorted out. Graphene does have excellent mechanical and electrical properties but it is not necessarily the 'miracle material' that the media portray it as and I wouldn't be surprised if we are still "just talking" about it in 10 years time. However, if the aforementioned issues can be overcome then I definitely think it will be revolutionising electronics, civil engineering and medicine in the coming decades.
How do you derive graphene's low-energy Hamiltonian?
ask Liviu Chibutaru
What is an exception of non-metals with high tensile strength?
Carbon Nano Tubes, Graphene.
What is the most elastic substance in the world?
Lead is the most stretchable of any element.
What is a graphene filter?
Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
What are the materials that are strong?
One of the hardest substances found in nature is the diamond. One of the strongest man made materials is called graphene.
What are the properties of graphene?
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
How does graphene form?
Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
What is graphene?
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
How does the molecular structure of graphene differ from the other allotropes of carbon diamond and graphite?
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
What is the hardness of graphene on the mohs scale?
graphene according to how much it can hold (calculator) and how dense it is.
How strong is Graphene?
It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap."
Is graphene used in armor and reason out the answer?
no
Is graphene used in armor?
No, not yet.
What is the density of graphene and carbyne?
Graphene aerogel - 0,16 mg/cm3 (7,5 less than air) Carbyne - 3430 mg/cm3
Where can you buy graphene paper?
Graphene is an allotrope of carbon, and is a single layer thick body with the atoms arranged in a hexagonal positions on a sheet. There are as yet serious limits to the size of the sheets, and this is determined it seems by the nature of the substrate on which it is produced.Graphene could be produce in different ways : Exfoliation, Carbon Vapor Deposition, Synthesis on Silicon Carbide. Historically, the method was to use tape on graphite, and detach the graphene layers from the tape film. Depending on your applications you can decide among different kind of graphene.Produced by exfoliation from graphite is rather expensive - perhaps $100 000 000 per sq cm. And only in tiny pieces. Produced by carbon vapor deposition, graphene is cheaper and could be deposited on a wide range of substrates.This field is very rapidly developing. To support the research, the European Union have in 2013 announced research grants to take graphene out of the laboratory into industry. The web site will carry news as developments are made. In the meantime, there are suppliers who are able to supply graphene on a number of substrates. A little research time will help to find the supplier that best meets your needs.
