Fig. 3.3 Histograms of elastic modulus distribution of AFM mapping images: a–e are five different
typical zones of interest for MBCs. Elastic modulus mapping distribution is fitted with Gaussian
distribution curves for data histograms [9]
3.2.3 FTIR and XRD Analyses
FTIR spectra are shown in Fig. 3.4a to investigate the surface functionality of asreceived MBCs and NBCs. The peaks at approximately 2439.6 and 2417.5 cm

are assigned to the C≡H stretching [22]. Whereas, the peaks about 1567.4 and
