Aggregated diamond nanorods (ADNRs) can be used in applications requiring extreme hardness and strength, such as cutting tools, drilling equipment, and electronics. They also have potential in areas like high-pressure experiments and as a new type of carbon allotrope for research and development.
No, carbon cannot be removed from a diamond as it is a pure form of carbon. The structure of a diamond is a tightly bonded network of carbon atoms, and it is not possible to chemically or physically remove the carbon without altering the structure of the diamond.
Got that backwards- diamonds are composed of carbon. But not all carbon is diamond.
The oxidation number of a carbon atom in diamond is 0, because carbon atoms in diamond have a formal charge of 0. Each carbon atom in diamond is bonded to four other carbon atoms, forming a tetrahedral structure, and there are no net charges on the molecule.
If you think to diamond as a carbon allotrope, the chemical symbol of carbon is C.

Diamond has an extremely strong covalent bonding between carbon atoms; today diamond is not considered the hardest material, Today the hardest material is Aggregated diamond nanorods.
Aggregated Diamond NanorodsADNRs, are an allotrope of carbon believed to be the hardest and least compressible known material, as measured by its isothermal bulk modulus; aggregated diamond nanorods have a modulus of 491 gigapascals (GPa), while a conventional diamond has a modulus of 442 GPa. ADNRs are also 0.3% denser than regular diamond.The ADNR material is also harder than type IIa diamonds and ultrahard fullerite.A process to produce the substance was discovered by physicists in Germany, led by Natalia Dubrovinskaia, at the University of Bayreuth in 2005.ADNRs are made by compressing allotropic carbon fullerene molecules (generally 60 carbon atoms per molecule) to a pressure of 20 GPa, while at the same time heating to 2500 Kelvin, using a unique 5000 metric tonne multi anvil press. The resulting substance is a series of interconnected diamond nanorods, with diameters of between 5 and 20 nanometres and lengths of around 1 micrometre each.They have used diamonds to cut steel.Its diamond
Graphene is not the hardest material in the world; it is actually one of the strongest and lightest materials known. Graphene's strength comes from its unique structure, where carbon atoms are arranged in a single layer. While graphene has impressive strength-to-weight ratio, there are harder materials like diamond or aggregated diamond nanorods.
The hardest substance on earth are things called Carbon Nanotubes. It's quite some times harder than diamond earning it well above a 10 on the Mohs Scale. This object is synthetic, being made by man. However, there is another substance called Rhenium diboride that is also harder than diamond; another from of a nanotube.
steel boron carbide is stronger than steel I do believe To date, probably carbon nanorods. Carbon is strongest, but in might be nanorods, nanotubes, or fiber. I'm not sure. A particular arrangement of carbon called Lonsdaleite (both naturally occurring in trace amounts and manufactured) is the hardest known material to date. pure samples have been recorded to be 58% harder than diamond, however when found naturally, impurities cause the Mohs Hardness to be only 7-8 (diamond is 10 on this scale).
The hardest known metal alloy, and the hardest known metal in general, is a type of carbon steel, Alloy 1090. With a tensile strength of .84 GPa (122,000 psi) and a yield strength of .64 GPa (67,000 psi), carbon steel is surpassed in hardness only by very hard nonmetals, such as ruby, diamond, or aggregated diamond nanorods. The best high-carbon steels rate an 8 on the Mohs scale of hardness, relative to ruby at 9 and diamond at 10. The hardest metals are still somewhat soft in comparison to the strongest nonmetals, based on the strongest bonds in chemistry, the sp2 bond between carbon atoms. High-strength carbon steel goes through a process of tempering and annealing to make it harder. After this process is complete such steel is called strengthened steel, the hardest metal available. Carbon contents as great as 2% may be present in the hardest metal..
The hardest known naturally occurring material is diamond, which is composed of carbon atoms arranged in a strong, rigid crystal structure. However, scientists have also created synthetic materials that are harder than diamond, such as aggregated diamond nanorods.
Diamond is the diamond form of carbon
A diamond is composed of carbon atoms arranged in a specific crystal lattice structure.
No, carbon cannot be removed from a diamond as it is a pure form of carbon. The structure of a diamond is a tightly bonded network of carbon atoms, and it is not possible to chemically or physically remove the carbon without altering the structure of the diamond.
