Laser Creates Diamonds at Room Temperature

Jan-27-19 A room-temperature method of creating diamonds from carbon fibers could make the precious material more accessible for use in computers, tools and jewelry.

While diamonds can be created in the lab, the technique typically requires bulky equipment and extreme heat and pressure—and results in a limited yield. In contrast, the new method from the team at North Carolina State University relies on heating the carbon nanofiber with a 100-second nanopulse, instantly melting the material. The heat is controlled using a substrate, preventing the carbon from turning to gas. That material is then cooled quickly, which causes the carbon to crystallize into a diamond.
