Two-minute assembly of pristine large-area graphene based films.
We report a remarkably rapid method for assembling pristine graphene platelets into a large area transparent film at a liquid surface. Some 2-3 layer pristine graphene platelets temporally solvated with N-methyl-2-pyrrolidone (NMP) are assembled at the surface of a dilute aqueous suspension using an evaporation-driven Rayleigh-Taylor instability and then are driven together by Marangoni forces....
متن کاملLarge and pristine films of reduced graphene oxide
A new self-assembly concept is introduced to form large and pristine films (15 cm in diameter) of reduced graphene oxide (RGO). The resulting film has different degrees of polarity on its two different sides due to the characteristic nature of the self-assembly process. The RGO film can be easily transferred from a glass substrate onto water and a polymer substrate after injection of water mole...
متن کاملImpact of crystalline quality on neuronal affinity of pristine graphene.
Due to its outstanding mechanical and electrical properties as well as chemical inertness, graphene has attracted a growing interest in the field of bioelectric interfacing. Herein, we investigate the suitability of pristine, i.e. without a cell adhesive coating, chemical vapor deposition (CVD) grown monolayer graphene to act as a platform for neuronal growth. We study the development of primar...
متن کاملSelective gas sensing with a single pristine graphene transistor.
We show that vapors of different chemicals produce distinguishably different effects on the low-frequency noise spectra of graphene. It was found in a systematic study that some gases change the electrical resistance of graphene devices without changing their low-frequency noise spectra while other gases modify the noise spectra by inducing Lorentzian components with distinctive features. The c...
متن کاملPlasma-assisted Electrochemical Synthesis of Pristine Graphene Sheets
Graphene is a two-dimensional form of graphite made up of a single layer of carbon atoms in a honeycomb lattice that has attracted tremendous interest for its novel physical properties. A key challenge that has emerged is how to synthesize large amounts of graphene (large area or mass) at low cost. The objective of this project is to explore an entirely new method to exfoliate graphene from com...
