Diamondoid |
|
A
diamondoid, in the context of building materials for nanotechnology components, most generally
refers to structures that resemble diamond in a broad sense: namely, strong,
stiff structures containing dense, 3-D networks of covalent bonds, formed chiefly from first and second row atoms with a valence
of three or more. Examples of diamondoid structures would include crystalline
diamond, sapphire, and other stiff structures similar to diamond but with
various atom
substitutions which might include N, O, Si, S, and so forth. Sp˛-hybridized carbon structures that - in contrast to
spł-hybridized carbon
in diamond - arrange in planar sheets ("graphene"
sheets) are sometimes also included in the class of diamondoid materials for nanotechnology, e.g., graphite, carbon
nanotubes
consisting of sheets of carbon
atoms rolled into tubes, spherical buckyballs and other graphene
structures.

Structures
that resemble diamond in a broad sense, strong stiff structures containing
dense, three dimensional networks of covalent bonds;
diamondoid materials could be as much as 100 to 250 times as strong as
titanium, and far lighter.

As
used in this volume, this term describes structures that resemble diamond in
a broad sense: strong, stiff structures containing dense, three-dimensional
networks of covalent bonds,
formed chiefly from first and second row atoms
with a valence
of three or more. Many of the most useful diamondoid structures will in fact
be rich in tetrahedrally coordinated carbon.
Diamondoid is used more narrowly elsewhere in the literature.

components, or a variety of other earth-bound articles for which weight and
strength are a consideration.
