At 2 months the follicles presented a high capability to bind radioiodide, which decreased and disappeared in the follicles lined with flat cells at 6 and 10 months.
Even at a high rate capability of 100 A/g, the NSMCs electrode still shows the SC value as high as 232 F/g, retaining 83% of that at 1 A/g.
Mixed metal oxides, e.g. ruthenium oxide (RuO2), manganese oxide (MnO2), magnetite (Fe3O4) [ 45– 47], CNTs [ 8, 48], graphene [ 49, 50] and carbon-metal oxide composites [ 51] have been investigated as electrode NMs aimed at a high specific capacity and rate capability [ 52, 53].
Capacitance values of 85 F g−1 and 245 F cm−3 were obtained at 2 mV s−1, with a high rate capability and good cyclability.
