New Material Harder Than Diamond

Posted by ScuttleMonkey on from the thats-one-gem-thats-hard-to-imagine dept.

h4x0r-3l337 writes "Diamond is no longer the hardest substance known to man. Scientists have created a new material, called "aggregated diamond nanorods" by compressing carbon-60 under high heat. From the article: 'The hardness of a material is measured by its isothermal bulk modulus. Aggregated diamond nanorods have a modulus of 491 gigapascals (GPa), compared with 442 GPa for conventional diamond.'"

    "Carbon is the most electronegative element with a valence of 4."

    Sorry, but this is wrong. The most electronegative element is Flour, with a value of 3.98, while carbon only has a value of 2.55.

    The reason that carbon is so interestion is not its electronegative capacity, but ist structure. It can form a lot of complect shapes, rings, tubes, etc... this makes it strong.

    I love playing Diablo II with one of those, but I got bored because all she does it shoot arrows at stuff. Oh, Borazon... Nevermind.
