This fringe distance conforms to (110) of tungsten, as indicated in JCPDS card no.
The lattice-fringe distances observed from the enlarged HRTEM images of Fig. 2 and Additional file 1: Figure S1 also suggest that the structural details of host CdS QDs have hardly been modified by the incorporation of 2% Cu ions.
Figure 3c shows the lattice fringes with an inter-fringe distance of 0.45 and 0.33 nm, corresponding to (200) of NMO and (004) of CNT, respectively.
The measured inter-fringe distance is 0.232 and 0.230 nm, respectively, being close to the {111} lattice spacing of fcc FePt (~0.235 nm).
Shown in Figure 2 is the high-resolution transmission electron microscopy (HRTEM) image of the FePt nanocubes; the inter-fringe distance of the lattice fringes is measured to be 0.196 nm, being close to the lattice spacing of the (200) facet of the face-centered cubic (fcc) FePt alloy.
The observed lattice-fringe distance in Fig. 2b is 0.336 nm, which agrees well with the standard spacing of 0.336 nm between the adjacent (111) lattice planes of the cubic zinc-blende crystal of CdS. Figure 2c and Table 1 indicate that the average value of the major and the minor axes calculated from HRTEM images of the e-Cu CdS QDs is 2.6 ± 0.4 nm.
It is revealed that both the fringe tortuosity and separation distance decrease as combustion proceeds, while the mean fringe length increases distinctly from 1.00 to 2.13 nm, indicating the soot evolution toward a more graphitic structure during the combustion process.
The degree of disorder of graphene layers (RS analysis bands), fringe interspace distance (∼1.5 nm with XRD, and ∼0.46 nm with HRTEM), fringe length (∼2.5 4 nm with XRD, and ∼0.9 nm with HRTEM), median fringe tortuosity (∼1.1), mean primary particles diameter (∼25 nm), and fractal dimension (∼2.3) were similar for all soot samples.
(26.2 mm) with a maximum fringe field distance of 0.065 in.
