(a) Schematic illustration
of acid-assisted etching and exfoliation
to obtain TaS2 monolayers for the fabrication of MSC.39 (b) CV curves at different scan rates and (c)
cycling stability of the MSP-TaS2-based MSC at a current
density of 2 A g–1; the inset is the GCD curves
at the 1st and 4000th cycle. Schematic diagram of (d) the phase transition
from state I to state III and (e) simulation of proton adsorption
in the 2H, 1T, and mixed 2H-1T phases of MoS2.41 (f) Specific conductivity of three states and
their corresponding Rct values. (g) Scheme
to visualize the one-body array of core/shell nanowires (left), and
corresponding ADF-STEM image of WO3/WS2 core/shell
nanowire (right).47 (h) Optical image under
mechanical bending (left), and corresponding SEM image (right) of
densely aligned core/shell nanowires; the inset shows their faceted
surface. (i) Cycling performance at a scan rate of 100 mV s–1. Reprinted with permission from refs (39, 41, and 47). Copyright
