In a mesoscale discovery assay, antibodies adsorb onto electrodes made from this element. Boron is doped into this element to form an electrode with the widest known electrochemical window. Vanadium moves past a felt made of this element in a redox flow battery. A vitreous form of this element is polished with silicon and slurried with alumina to attain electrochemical purity. To make electrodes for CV, this element is either mixed into Nujol to form a paste, (-5[1])or it is subjected to highly ordered (*) pyrolysis. The double layer formed when a voltage is applied to this element guarantees the storage of supercapacitors. (10[1])The cathode for the Hall-Héroult process (-5[1])and the anode for a lithium-ion (10[1])battery are both (10[1])made (10[1])of this element’s hexagonal allotrope. (10[1])For 10 points, name this element found in fullerenes and (10[1])graphite. (10[3]) (10[3])■END■
