It is now quite apparent that nanoparticulate materials of virtually all types (morphologies, chemistries, crystal structures, crystallinity variations, etc.) pose a variety of health hazards, particularly respiratory hazards.

We can clearly identify the single wall structure from this image.

If negative pressure exceeds the structure intensity, cavitation will formed.
So the staining method is an ideal method to test acoustic intensity in acoustic machining and acoustic chemistry, and could also provide references to improve ultrasonic cleaning process.
