• MWPECVD. Emphasis was placed on a reproducible dopant addition to the growth process aiming at a targeted in situ incorporation of color centers based on nickel and tungsten impurities. A very promising single-photon-emitting defect for quantum-cryptographic applications is the so-called NE8-center [17

• nanowires were successfully grown from nickel [57], cobalt [79], and iron [80]. The growth of Fe-based nanowires with controllable size, aspect ratio, and magnetic anisotropy in FeCl3 and FeCl2 solutions was investigated by Song et al. They employed FeCl3 and FeCl2 solutions, studied the nanowire growth

Then, a post-annealing treatment favors the metal-catalyzed crystallization of carbon into stacked graphene layers rolled around the nickel cores. The

• different sites on the C60 molecule. It can be seen that nickel has the strongest binding energy but with zero total magnetization (MT), and thus, is probably not interesting for investigations of spin transport. On the other hand, chromium enjoys the largest MT, due to its largest unpaired electronic

Consequently, this leads to the possibility that the remaining one or two electrons of each surface atom in diamond react readily with other materials like iron, nickel and even silicon [16] in a tribological
