We can also observe in cross-sectional image in Figure 4c,d that the NWs are packed at the bottom in comparison with the surface where we can see lesser number of NWs sprouting out of the thickness.To determine the purity and composition of the sample, energy-dispersive analysis X-ray (EDAX) analysis was carried out.
The corrosion products have a multilayer microstructure that can be observed in cross section and optical microscopy.
The "cell-like" structures observed in cross section samples are cross sections of these long cells and of the Al-Si eutectic at cell boundaries.
When observed in cross section, the ash particles display a variety of shapes, both euhedral and anhedral, with skeletal polygonal shapes with four and five sides being the most characteristic (Fig. 4).
In a large number of measuring and characterization methods, the sphere size distribution of particles embedded in a medium has to be estimated from profile radii observed in cross sections or thin slices.
This number was confirmed by the presence of only 2 to 4 nanoparticles per cell in nanocellular PS and PMMA foams containing SiO2 nanoparticles with a PDMS shell as was observed in cross sectional SEM images.
In these samples membranous stacked tubules of ∼15 nm diameter were observed in cross sections and tangential sections (Fig. 4E, inset).
Still, different fibrillar assemblies are observed in cross section as well.
A significantly female-biased sex ratio was observed in Cross 1 (G = 8.26, DF = 1, P = 0.004) and non-significant female bias was observed in 5 other crosses.
Positive X-gal staining was also observed in cross sections left unstained or counter stained with H&E.
In fact, among the QTL clusters identified from cross P, 66% were also observed in cross D for bud flush, 60% for bud set, and 100% for height growth.
