LOOK AGAIN
See if you can find the 8 differences in each set of images.
Fe2O3 nanostructures
Ladybugs
Fe2O3 nanostructures thermally grown on sintered Fe nonporous bulk material.
This field-emission scanning electron microscope image shows the morphology of porous WS 3 (tungsten trisulfide), which is imaged as small beetles, or ladybugs. The porous WS 3 shows dark black spots, and the spherical surface represents the body of the ladybugs.
