However, increase of the matrix mass after modification is inconsiderable (Table 1).The transmission electron microscopy (TEM) image of powder of the pristine membrane is given in Figure 4a.
The SEM images of powder H-ZSM-5, ceramic foam-coated H-ZSM-5 and uncoated foam are shown in Fig. 3a c, respectively.
Aggregates of particles I and II are located on the surface of particles III.Figure 4b,c,d shows TEM images of powder of the modified membrane.
Generally, a smaller particle size was observed in the particle size distribution analysis of the sample powders than in the SEM image because the powders were dispersed in solution for the particle size distribution measurement.
Figure 5 shows the EDS images of iron powder in Column 1 and Column 2. Figure 5a, b shows the scanning zones of iron powder and the image of the EDS of Column 1. Figure 5c, d shows the scanning zones of iron powder and the image of EDS of Column 2. From the images, it was clear that Column 1 and Column 2 contained the same elements of carbon, oxygen, silicon, calcium, chromium and iron.
Fig. 6 SEM image of FBE powder at a ×500 and b ×1500 (backscattered electrons, BSE).
(A) TEM image of Si powder initially suspended in ethanol and deposited on a graphite grid.
The SEM image of In2S3 powder shows micro-sized 3D chrysanthemum-like shapes are formed by aggregation of wedge like nanosheets.
In tests where the researchers dragged one box across another and created cracklike voids in the powder (image), the opening and closing of the defects triggered substantial changes in voltage, as well.
The unilateral illumination setup brings about a significant simplification of traditional image analysis in powder studies, which is usually orientated towards characterizing all individual particles before aggregating this information.
