A proposito di questo titolo

If you look inside a diamond, you may find something even more valuable than its spectacular brilliance. Diamonds form deep within Earth’s mantle, of pure carbon. Their atomic bonds are so strong that they’re Earth’s hardest mineral and our best conductor of heat. These properties make diamonds valuable for industrial purposes—like on drill bits or rock saws, or in electronics for extreme environments. But that’s not the big surprise. A diamond’s pure carbon structure makes it very clear. But sometimes trace amounts of boron or nitrogen, the elements on either side of carbon on the periodic table, will sneak in. Boron turns a diamond blue, like the famous Hope Diamond. Nitrogen turns it yellow. Normally, this would make a diamond less desirable. But it’s nitrogen that could make diamonds more valuable than ever. Scientists at the City College of New York have figured out how to activate the nitrogen with red and green lasers, allowing them to store and erase data in three dimensions along the diamond’s crystal structure, at the atomic level. Think about that. The technology is in its early stages, but researchers believe a diamond the size of a grain of rice could store the entire Library of Congress—five hundred times. Think about that. In the future, diamonds could open the possibility for tiny computers or medical devices to bring a shine to our lives that we can only imagine.
