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).

] is not always necessary to achieve the expected compressive strengths of 200MPa.Adjusting the packing density, flowability and other properties of the cementitious proportions combined with the use of very high strength, fine-diameter steel fibers and ensuring the bond between all the materials can make up for the loss and has been proved on 2-inch (50-mm) cubes.
