Posted by glenn under Science
 

United States Patent 6,582,513
Linares , et al. June 24, 2003

Abstract
Synthetic monocrystalline diamond compositions having one or more monocrystalline diamond layers formed by chemical vapor deposition, the layers including one or more layers having an increased concentration of one or more impurities (such as boron and/or isotopes of carbon), as compared to other layers or comparable layers without such impurities. Such compositions provide an improved combination of properties, including color, strength, velocity of sound, electrical conductivity, and control of defects. A related method for preparing such a composition is also described, as well as a system for use in performing such a method, and articles incorporating such a composition.

Even though the possibility of such an attack had been widely anticipated by computer security experts, the worm managed to take advantage of a vulnerability in a common component of Windows to invade numerous computer hard drives, where it was in position to impede operations and attack other computers.
