Figure 4

Silica rods R2 (a,b,d–f) and R3 (c) with ϕ=0.005. (a,b) Confocal images of the rods oriented by different field directions. (c) In-plane angular distribution of rods on a crystal lattice as a function of field strength. (d) Nematic order parameter (2D) and corresponding field strength as a function of time. (e) Nematic order parameter (2D) versus field strength, showing the absence of hysteresis. The designated time points were 0, 14, 35, 65, 89, 133, 161, 188, 228, 253, 286, 310, 340, 355 s. The vertical error bars are the s.d. of the calculated values displayed. (f) Fast switching between the on-state (same orientation) and off-state (random orientation). The scale bars in (a) and (b) represent 10 μm.
