Many interesting properties of graphene and few layer graphite have put this material at the foreground of present day nanosciences. Graphene is mechanically hard and extremely flexible, chemically inert, impermeable to any atom or molecule, optically transparent. It is a zero-gap semiconductor, easily made conducting by electrostatic charging, the charge carriers having then a remarkable mobility, and it has an excellent thermal conductivity.
The unique properties of graphene make it suitable for many potential applications. Composite polymers based on it are light materials that can become, e.g., transparent electrodes or microwave absorbers. The electronic properties of graphene depend strongly on its environment, which makes it a good candidate for sensing. These graphene nanoribbons that become semiconducting due to lateral confinement may become ultra-fast field-effect transistors. Graphene has potential applications in nano electromechanical systems, most particularly as resonator having a very high sensitivity.
All the cited foreseen applications, and other, will require extensive work to become reality, if they ever do. There are indeed many difficulties to overcome. Due to its extremely small thickness, graphene is not easily to manipulate: it can fold, break, or simply get lost. Graphene produced by CVD is not free of defects, grain boundaries in particular, which degrade its intrinsic properties. Possible toxicity and environmental effects are important issues to be addressed before graphene enters industry. The route towards real applications is still long and is sprinkled with various technological challenges.
For around the last ten years, fundamental research has been paving the way toward practical applications of graphene . Progressively, worldwide efforts have led to a better knowledge of synthesis and growth mechanisms, to a deeper understanding of the effects, defects, and interactions of the substrates that hold graphene, to an increasing know-how in the manipulation of samples and atomically precise positioning, etc. This special issue is expected to gather contributions that describe recent results obtained in various active fields of graphene science and demonstrate how said results can be important in light of applications.

Title: Elastic Properties of Graphene
Author: Philippe Lambin
Affiliation: Physics Department, University of Namur, 61 Rue de Bruxelles, B-5000 Namur, Belgium
Abstract: Graphene is an ultimate membrane that mixes both flexibility and mechanical strength, together with many other remarkable properties. A good knowledge of the elastic properties of graphene is prerequisite to any practical application of it as a membrane in nanoscopic devices. Although this two-dimensional material is only one atom thick, continuous-medium elasticity can be applied as long as the deformations vary slowly on the atomic scale and provided suitable parameters are used. The present paper aims to be a critical review on this topic. The basis for the paper is the classical Kirchhoff-Love plate theory. It demands two parameters that can be addressed from many points of view and fitted to independent experimental data. The parameters can also be estimated by electronic structure calculations. Although coming from diverse backgrounds, most of the available data provide a rather coherent picture that gives a good degree of confidence in the classical description of graphene elasticity. The theory can than be used to estimate, e.g., the buckling limit of graphene bound to a substrate. It can also predict the size above which a scrolled graphene sheet will never spontaneously unroll in free space.
