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.
That's why initiatives such as the Pistoia Alliance and Allotrope
Foundation are important.
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].
4 March 2014 - US 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 , 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].
