Spectrophotometric analysis of CNCs formation with different reagent ratios or reaction pH and analyses of CNCs size obtained by dynamic light scattering. Representative Vis-absorbance spectra at 630 nm of (a) the tested conditions according to the proportions of hydrolysed rice husk and straw suspension (HR), water, and ethanol at pH 7 and (b) of the HR : water : ethanol 1 : 1 : 2 (v/v/v) suspension at different pHs. Histograms of the hydrodynamic diameter using the number of events distribution of the suspensions at pHs 5 (c), 7 (d), 9 (e), and 11 (f).
