Capacitive deionization (CDI) is a water desalination technology in which salt ions are removed from brackish water by flowing through a spacer channel with porous electrodes on each side. Upon applying a voltage difference between the two electrodes, cations move to and are accumulated in electrostatic double layers inside the negatively charged cathode and the anions are removed by the ...

A technique of wire electrochemical micromachining (WECMM) with a carbon nanotube fiber (CNF) as tool electrode is proposed for microstructure fabrication of metallic glass. WECMM is a type of electrochemical micromachining (ECMM) that is increasingly recognized as a flexible and effective technology to fabricate complex-shaped micro components.
Before the use or invention of the carbon fiber electrode, Ralph Adams implanted his carbon paste microelectrodes into a rat brain in the 1970's. This was a major breakthrough for neuroscientists in that time. Adams is the scientist generally credited with being the one who first measured the . in vivo
