In 2001, a diamond-like-structured c-BC 2 N was synthesized at pressures >18 GPa and temperatures >2,200 K by a direct solid-state phase transition of graphite-like (BN) 0.48 C 0.52. The reported Vickers and Knoop hardnesses were intermediate between diamond and c-BN, making the new phase the second hardest known material. [ 39 ]
A programmable material that the Transformers are made from. Tritanium: Star Trek: The fictional metal tritanium was referred to in many episodes as an extremely hard alloy used in starship hulls and hand-held tools. Eve Online: A versatile material; the primary material used in the construction of virtually all star ships and star ship components.
The luster of a diamond is described as "adamantine", which simply means diamond-like. Reflections on a properly cut diamond's facets are undistorted, due to their flatness. The refractive index of diamond (as measured via sodium light, 589.3 nm) is 2.417. Because it is cubic in structure, diamond is also isotropic.
A diamond simulant is a non-diamond material that is used to simulate the appearance of a diamond, and may be referred to as diamante. Cubic zirconia is the most common. The gemstone moissanite (silicon carbide) can be treated as a diamond simulant, though more costly to produce than cubic zirconia.
Diamond nanoparticles have the potential to be used in myriad biological applications and due to their unique properties such as inertness and hardness, nanodiamonds may prove to be a better alternative to the traditional nanomaterials currently utilized to carry drugs, coat implantable materials, and synthesize biosensors and biomedical robots ...
The adjective adamant has long been used to refer to the property of impregnable, diamond-like hardness, or to describe a very firm/resolute position (e.g. He adamantly refused to leave ). The noun adamant describes any impenetrably or unyieldingly hard substance and, formerly, a legendary stone/rock or mineral of impenetrable hardness and with ...

In 1994, Srinivasan Chandrasekar, an engineering professor at Purdue University, and Munawar Chaudhri, head of the materials group at the University of Cambridge, used high-speed framing photography to observe the drop-shattering process and concluded that while the surface of the drops experiences highly compressive stresses, the inside ...
