During the experiments, SEM and TEM images of SiO2 nanoparticles have been taken in different magnification. The main purpose of scanning the images in low magnification orders is to observe the nanoparticles adhesion in micron size in the samples. So, if nanoparticles changed to micro-size cluster by adhesion, in this case, it is impossible to observe the existing clusters in nano images in ×50.000 and more magnification. Therefore, first let us review SEM images scanning with micron-size images and ×5.000 and ×20.000 magnification (1 μm inde
