Koh et al. researched the comparative dispersion studies of SWCNTs in aqueous solution by UV-vis-NIR absorbance measurement and AFM, and found that a low powder and short time of sonication to disperse SWCNT to preserve their average lengths [4].
c = A/ɛL (1) where c is the actual concentration of SWCNTs, A is the absorbance of SWCNTs, ɛ is an estimated extinction coefficient of HiPco SWCNTs, which is 17.4 (mg/mL)-1 cm-1 at 808 nm [4], and the L is the light path length (i.e., L = 10 mm).

According to Greene et al. [7], ZnO NRs tend to stabilize their facet through shape transition by experience reconstruction which can change the rods diameter, while at the same times the sharp tapper end tips will evolve to flat hexagonal layout.
