Abstract: A process for preparing surface-modified carbon, comprising adding carbon material to a solution of a reaction product of primary aromatic amine and excess molar amount of nitrite source, and recovering surface-modified carbon bearing redox-active sites. Surface-modified carbon material, electrodes and capacitors based thereon are also provided.

Abstract: A hinge pin joint for facilitating precise separation of the jaws of a spring clip, including a base cylinder with a threaded bore, supports extending laterally out from the base cylinder, pin supports capable of pivoting, and stabilizing wings extending from the pin supports. In one embodiment, the capability of pivoting includes pins that are integral with the pin supports and which extend out laterally from the pin support. An alternate embodiment includes aligned opening in the pin supports into which pins may be inserted. At least one stopper may be disposed on at least one of the pin supports for supporting the upper shell. The stabilizing wings are configured as plates that are semi-rigidly secured in guide structures within the lower shell.
