A reinforced concrete material is described comprising a cementitious material () in which graphene is substantially uniformly distributed. A method of production of concrete is also described comprising the steps of forming a substantially uniform suspension () of graphene with water, and mixing the suspension () with a cementitious material () to form a concrete material ().

Graphene reinforced concrete

Methods of producing a uniformly or substantially uniformly doped relatively large area multi-layered graphene element are described comprising the steps of placing the graphene element and a dopant under low pressure conditions, and holding the graphene element and dopant at an elevated temperature for a period of time while under the low pressure conditions. In one arrangement, openings are formed in a multi-layered graphene element of relatively large area prior to doping. In another arrangement, a relatively large area multi-layered graphene element formed by an epitaxial growth technique is used. The invention also relates to an element produced using the aforementioned techniques.

Doped graphene

The present invention relates to a transparent chemically functionalized graphene with high electrical conductivity and which is stable in air. It also relates to a method of manufacturing a conductive and transparent graphene-based material.
