Graphene doped with various gaseous species (both acceptors and donors) can be returned to an undoped state by gentle heating in vacuum. [22] [24] Even for dopant concentrations in excess of 10 12 cm −2 carrier mobility exhibits no observable change. [24] Graphene doped with potassium in ultra-high vacuum at low temperature can reduce ...
[27] [28] Graphene–based materials such as graphene oxide (GO) have considerable potential for several biological applications including the development of new drug release system. GOs are an abundance of functional groups such as hydroxyl, epoxy, and carboxyl on its basal surface and edges that can be also used to immobilize or load various ...
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 ...
A rapidly increasing list of graphene production techniques have been developed to enable graphene's use in commercial applications. [1]Isolated 2D crystals cannot be grown via chemical synthesis beyond small sizes even in principle, because the rapid growth of phonon density with increasing lateral size forces 2D crystallites to bend into the third dimension.

In September 2009, De Heer was awarded the ACSIN Nanoscience Prize "for his visionary work in developing the field of graphene nanoscience and technology". [24] De Heer has been awarded the 2010 Materials Research Society Medal "for his pioneering contributions to the science and technology of epitaxial graphene". [25] His h-index is currently ...
An electrochemical reaction is a combination of two half-cells and multiple elementary steps. Each step is associated with multiple forms of overpotential. The overall overpotential is the summation of many individual losses. Voltage efficiency describes the fraction of energy lost through overpotential.
Samsung has funded $120,000 for research into the graphene antenna to a team of researchers from the Georgia Institute of Technology and the Polytechnic University of Catalonia. Their research has shown that graphene is a feasible material to make nano antennas with.
The Annual Review of Materials Science was first published in 1971 by the nonprofit publisher Annual Reviews, making it their sixteenth journal. [3] Its first editor was Robert Huggins. [4] In 2001, its name was changed to the current form, the Annual Review of Materials Research. The name change was intended "to better reflect the broad appeal ...
