The two most common allotropes of pure carbon are diamond and graphite. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. Main article: Material properties of diamondĭiamond is a solid form of pure carbon with its atoms arranged in a crystal. Natural, synthetic and imitation diamonds are most commonly distinguished using optical techniques or thermal conductivity measurements. Imitation diamonds can also be made out of materials such as cubic zirconia and silicon carbide. Synthetic diamonds can be grown from high-purity carbon under high pressures and temperatures or from hydrocarbon gases by chemical vapor deposition (CVD). Much more recently (hundreds to tens of million years ago), they were carried to the surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites. Under high pressure and temperature, carbon-containing fluids dissolved various minerals and replaced them with diamonds. Most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the Earth's mantle, although a few have come from as deep as 800 kilometres (500 mi). Most natural diamonds have ages between 1 billion and 3.5 billion years. Diamond also has a very high refractive index and a relatively high optical dispersion. Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.īecause the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Transparent to subtransparent to translucentĭiamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Less often blue, green, black, translucent white, pink, violet, orange, purple, and red. Typically yellow, brown, or gray to colorless. Its lustrous faces also indicate that this crystal is from a primary deposit. “We are predicting we can actually apply the technology in cars within the next two or three years.The slightly misshapen octahedral shape of this rough diamond crystal in matrix is typical of the mineral. “Also, the self-healing can be done at room temperature without applying heat,” Yeo added. Nissan applied a similar technology that self-paints the car, which takes around one week, while BMW’s recent technology requires one day. It will only take two hours to completely remove the scratches and cracks, way shorter compared to rival automakers who have developed similar technology. “Just like Wolverine and Terminator, the self-healing car can actually help increase the safety when cars are rapidly becoming autonomous these days,” said Yeo In-woong, a senior researcher at IATP.

The so-called 'self-healing coating' helps the car to remove scratches or cracks, on the exterior or cameras, on its own. One of the most notable technologies introduced is a feature that coats a car with macromolecules that return to their previous form. The images show the process of a scratch being removed by itself. “The technology innovation cannot come without an innovation in materials, which can determine the success of future mobility,” said Lee Jong-soo, head of Hyundai Motor’s Institute of Advanced Technology Development (IATP), during a press event introducing the technologies Thursday in central Seoul. A nanometer is one-billionth of a meter, or about 100,000 times smaller than the diameter of a human hair. Nanotechnology is the production of new structures, materials and devices by controlling shape and size at the nanoscale. Such “dream technologies” are what Hyundai Motor has been developing with nanotechnologies with the goal of commercializing them in two years at the earliest. Forgot to charge your electric vehicle, but there is no charger nearby? It is okay, solar cells on every window of your car will charge it automatically.

Got a small scratch on your car bumper? Do not worry, it would have fixed itself in less than two hours. Self-healing coating technology helps a car to remove scratches or cracks on its own.
