B is doublesided tape and C is a protective sheet of paper. (3) The bilayer device with a protective film is removed from the electrode. (4) The protective sheet is peeled off and the bilayer is ready to work. (Reprinted from Handbook of Organic Conductive Molecules ami Polymers, H.S.

Recently it was demonstrated that a platinum black-PTFE electrode, originally designed for a fuel cell, is excellent for the chlorination of double bonds and, depending on the other electrolysis conditions, it was possible to isolate the dichlorocompound or the chlorohydrin (Danger and Yurchak, 1970). Moreover, if a chlorine cathode is used, the overall process occurs with a net output of energy, i.e. the cell may do external work and the procedure has been named electrogenerative chlorination .

Equation (1) can serve as the basis for determining the highest reduction potential or the lowest oxidation potential of an electrocatalytic reaction. Figure 3 shows that spontaneous electroreductions result in a positive E° vs. NHE, often approached with the aid of a catalytic electrode (25, 26, 31, 33, 36). For the example of ethylene shown in Fig. 3, reduction can occur below its reversible potential away from equilibrium. If the ethylene electrode is combined with a hydrogen anode, an electrogenerative cell is formed (16,17,25,26,31,33,36), similar to a fuel cell, that can generate low-voltage. 

Here, we discuss an optimized DNA extraction method specifically for electrode-adhered biofilm communities. We describe the use of a biofilm DNA extraction kit from MoBio Laboratories Inc. to extract DNA from electrode-adhered communities (PowerBiofilm DNA Isolation Kit, www.mobio.com). Here, we included a slightly modified alternative for cell lysis to include less meehanical bead-beating and multiple heat treatments. This method for cell lysis has been found to be successful for electrogenic community analyses [18, 21], We do not endorse MoBio Laboratories. This protocol is solely meant to be a starting point for researchers. 

The reduction of NO to produce ammonia, N2O and hydroxylamine is thermodynamically allowed (see Table 1) and electrochemically viable [13,14]. On this basis, an electrogenerative process has been proposed whereby NO reacts in a cell with protons and electrons at one electrode and H2 at the other electrode to generate current [11]. Note that this configuration resembles that of a fuel cell (although the reactions are not necessarily the same), and the corresponding technology can be borrowed from that field. Electrogenerative processes can be defined as those in which favorable thermodynamic and kinetic factors are utilized for the production of coupled electrode reactions that take place in separate compartments in an...
