Fig. 9c shows the increase of all the studied thermoelectric properties of a SWCNT film doped with 2 wt% of Br2 molecules for a number of values of chemical potential for which the change in all the thermoelectric properties of doped film is positive with respect to the undoped film. While...
In conventional ZBB configuration, a porous membrane placing between the positive and negative compartment of ZBB acts as a barrier for Br2 crossover, while allowing the ionic conduction of Zn2+ and Br− 14, 15. Until now, several hundred micron-thick hydrophilic-treated porous polyethylene...
electrolyte circulation device unnecessary and to realize a compact size, by laminating cells of opposing positive and negative electrodes to make an electrode body, housing them in a cell main body of an enclosed structure, and rotating the cell main body at a specific rotational frequency or ...
During charge, metallic zinc is plated from the electrolyte solution onto the negative electrode surfaces in the cell stacks. Bromide is converted to bromine at the positive electrode surface of the cell stack and is immediately stored as a safe, chemically complex organic phase in the electrolyte...

The battery consists of a zinc negative electrode and a bromine positive electrode separated by a microporous separator. An aqueous solution of zinc/bromide is circulated through the two compartments of the cell from two separate reservoirs. The electrolyte stream in contact with the positive electrode...
Monatomic ions are created when neutral atoms gain or lose electrons to create an imbalance in the number of protons and electrons. This results in a net (overall) charge of the ion that is equal to the number of electrons s...
At the negative electrode:Zn2+ + 2 e− ↔ Zn (Eo = - 0.76 V versus SHE) Overall reaction: Zn2+ + 2 Br− ↔ Br2 + Zn (Eo = 1.84 V) During the charge process, Br2 is generated at the positive electrode and further complexes with Br− in aqueous media to form highly so...
(nBP)X structures (nBP n-bromopyridinium cations; X Br-or Cl-; n 2, 3, or 4) indicate that electrostatic effects, the positive charge on the bromopyridinium cation and the negative charge on the halide anion, play a major role in the strength and directionality of C−Br···X ...
areas but does not adhere to the uncharged, i.e., exposed, areas. The visible image which is thus formed may then be transferred to another surface resulting in a positive or negative print, or, if desired, it may be fused in order to fix the image directly to the solid substrate ...
