Amorphous materials inherit short-and medium-range order from the corresponding crystal
and thus preserve some of its properties while still exhibiting novel properties,. Due to its …

Solids in nature can be generally classified into crystalline and non-crystalline states,,,,,–,
depending on whether long-range lattice periodicity is present in the material. The …

New carbon forms that exhibit extraordinary physicochemical properties can be generated
from nanostructured precursors under extreme pressure. Nevertheless, synthesis of such …

Solid-state materials can be categorized by their structures into crystalline (having periodic
translation symmetry), amorphous (no periodic and orientational symmetry), and quasi …

Carbon is one of the most fascinating elements due to its structurally diverse allotropic forms
stemming from its bonding varieties (sp, sp 2 and sp 3). Exploring new forms of carbon has …

Diamond owes its unique mechanical, thermal, optical, electrical, chemical, and
biocompatible materials properties to its complete sp 3-carbon network bonding. Crystallinity …

Bulk amorphous materials have been studied extensively and are widely used, yet their
atomic arrangement remains an open issue. Although they are generally believed to be …

Compressing glassy carbon above 40 GPa, we have observed a new carbon allotrope with
a fully sp 3-bonded amorphous structure and diamondlike strength. Synchrotron x-ray …

The two natural allotropes of carbon, diamond and graphite, are extended networks of sp 3-
hybridized and sp 2-hybridized atoms, respectively. By mixing different hybridizations and …

C6o MOLECULES are extremely stable, withstanding hydrostatic pressures of up to at least
20 GPa (ref. 1). It has been proposed that at high pressures they could form a solid harder …
