Carbon has a variety of
allotropes owing to its capability of hybridization in sp, [sp.sup.2], and [sp.sup.3] bonds, which renders it able to form 0D (e.g., fullerenes), 1D (e.g., carbon nanotube), 2D (e.g., graphene), and 3D (e.g., diamond) structures and thus one of the most versatile elements in the periodic table.
Initiatives such as the Pistoia Alliance (www.pistoiaalliance.org) and
Allotrope Foundation (www.allotrope.org/) are successful precedents for this type of cooperation among life science organizations.
Company officials describe graphene as a "
allotrope of carbon ...
Similar to the plastics revolution of the 20th century, the carbon
allotrope seems eagerly poised to usher in"the age of graphene"in the 21st century.
Graphene--the two-dimensional
allotrope of carbon taking the form of a two-dimensional, atomic scale hexagonal lattice in which one atom forms each vertex--was discovered by University of Manchester scientists in 2004.
Abstract: Silicene is a monolayer
allotrope of silicon atoms arranged in a honeycomb structure with massless Dirac fermion characteristics similar to graphene.
Depending on their thickness, thin films of black phosphorus--an
allotrope of this element's familiar white or red forms--can be "tuned" to different semiconducting bandgaps that would make this material far more adaptable to various types of optical electronic switching.
It is an
allotrope of carbon--which along with diamond, graphite and Buckminster fullerene are all pure forms of carbon with the atoms bonded together in different structures.
Carbon nanotubes (CNTs), an
allotrope of Carbon composed of rolled layer of graphene, have very good electrical, thermal, optical, rheological and mechanical properties [10-16].

Allotrope Foundation, a consortium of pharma and biotech groups, said yesterday it had implemented its first Proof of Concept (PoC) application using its novel lab information Framework, thus achieving the first major milestone in the latter's development.
Graphene is an atom thick
allotrope of carbon in two-dimensional (2D) hexagonal honeycomb lattice [1], Electrons in a single-layer graphene exhibit a characteristic linear dispersion relation between energy and momentum near the K point of the first Brillouin zone (FBZ) [2-4].
