  • Nanoscale nuclear magnetic resonance with

    Nuclear magnetic resonance (NMR) spectroscopy is immensely useful for chemical characterization, but it requires relatively large amounts of sample. Recent studies have leveraged nitrogen vacancy centers in diamond to detect NMR signals from samples of just a few cubic nanometers, but with low resolution. Aslam et al. optimized this technique to achieve a resolution of 1 part per million

  • Grinding (abrasive cutting) - Wikipedia

    Grinding practice is a large and diverse area of manufacturing and toolmaking. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very hard materials than is "regular" machining (that is, cutting larger chips with cutting tools such as tool

  • Magnet Manufacturing Process | How Are

    Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence). Diamond is the hardest naturally occurring material known. Yet, due to important structural weaknesses, diamond's toughness is only fair to good.

  • What Are HPHT Diamonds? - The Brilliance

    To recreate the process that takes place deep inside the Earth's crust, HPHT diamonds are subjected to extremely high temperature and pressure inside special machines in a lab. Temperatures soar as high as 2,600 degrees Celsius to imitate the naturally occurring heat in the earth necessary to create a natural diamond. The exorbitant cost of the energy and machinery required to perform such a
