average of about 2.16%. The (110) plane exhibits exceptionally high strain of about
31.30% and is, therefore, excluded in estimating the average magnitude of strain.
As mentioned earlier in Table 4, the DMHNPLA samples have surface area much
higher than that reported (Liu et al. 2011) in literature. It happens due to large pore
volume with narrow size distribution of pores with an average size of only about
6 nm, Table 4 (Das et al. 2018).
3.2.3 Microstructural Studies
Figure 8 shows a typical illustrative FESEM photomicrograph of the threedimensionally self-assembled nanopowders which exhibit a connected micro dumbbell like microstructure. The average length and width of individual micro dumbbells are ~9 and ~1.9 μm, respectively (Inset Fig. 8). The photomicrograph (Fig. 8)
confirms the presence of beautiful flower-bud like microstructure comprised of
self-assembled particles of ~100–200 nm size.
