They are expected to be thermally and chemically more stable than diamond, and harder than c-BN, and would therefore be excellent materials for high speed cutting and polishing of ferrous alloys. These characteristic properties are attributed to the diamond-like structure combined with the sp3 σ-bonds among carbon and the heteroatoms.
A material 400 times harder than diamond, the 12th Doctor spends 4.5 billion years in a confession dial in the episode "Heaven Sent", continually dying and being recreated, taking the aforementioned 4.5 billion years to make it out of the confession dial by punching through an Azbantium wall.

Hypixel Network, [3] simply known as Hypixel, is a Minecraft server that hosts minigames. It was released on April 13, 2013 by Simon "hypixel" (name of player is not written like the name of the server, but with a lower h (see list of admins)) Collins-Laflamme and Philippe Touchette, and is managed and run by Hypixel Inc. [4] Hypixel is only available on the Java Edition of Minecraft, [5] but ...
A carbon nanothread (also called diamond nanothread) is a sp 3-bonded, one-dimensional carbon crystalline nanomaterial. The tetrahedral sp 3-bonding of its carbon is similar to that of diamond. Nanothreads are only a few atoms across, more than 300,000 times thinner than a human hair. They consist of a stiff, strong carbon core surrounded by ...
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 ...
In diamond, all the carbon-to-carbon bonds, both within a layer of rings and between them, are in the staggered conformation, thus causing all four cubic-diagonal directions to be equivalent; whereas in lonsdaleite the bonds between layers are in the eclipsed conformation, which defines the axis of hexagonal symmetry.
A <111> surface (normal to the largest diagonal of a cube) of pure diamond has a hardness value of 167±6 GPa when scratched with a nanodiamond tip, while the nanodiamond sample itself has a value of 310 GPa when tested with a nanodiamond tip. However, the test only works properly with a tip made of harder material than the sample being tested ...
The term nanoporous materials contain subsets of microporous and mesoporous materials. Microporous materials are porous materials with a mean pore size smaller than 2 nm, while mesoporous materials are those with pores sizes in the region 2–50 nm. [23] Microporous materials exhibit pore sizes with comparable length-scale to small molecules.
