     In 2005 scientists at Bayreuth University in Germany created a new material by compressing pure carbon under extreme heat. It’s called hyperdiamond or aggregated diamond nanorods (ADNR) and, although it’s incredibly hard, it looks rather like asphalt or a glittery black pudding.

     There are harder substances than diamond - In 2005, physicists Natalia Dubrovinskaia and colleagues compressed carbon fullerene molecules and heating them at the same time to create a series of interconnected rods called Aggregated Diamond Nanorods (ADNRs または "hyperdiamond"). It's about 11% harder than a diamond.
