What kind of applications does this bubblology have?

I don‘t know about nanobubbles, but microbubbles are used in contrast enhanced ultrasound. Basically overcoming the resolution limit of conventional ultrasound systems to create an image of your microvessels for medical diagnostics.

That's interesting. Why aren't they deleterious to the ultrasound resolution due to the constant refraction from the medium shift? Does that refraction change act like dithering in astronomical images?

Not the person you asked, but I think 'bubblology' (thank you for that word by the way) would have relevance in micro-fluidics, which relates to lab-on-a-chip applications and microbiology and cellular biology. It may also have mechanical engineering relevance through hydro-dynamics in (micro-)pumps, injectors, and carburetors. Maybe even drug delivery systems.

Edit: and according to this link it's also very useful for water aeration, which is needed for hydroponics, hydro-culture, and general water treatment.
In general for nano: lots of surface interaction, so great if you want to a lot of chemical or physical interaction between your nano-something and whatever substance you put it in.

yes, Moleaer is THE leading company developing nano bubble generators for industrial volumes. I use a 200 GPM unit for removing algae from a 75,000 m3 lake. It is quite a spectacular transformation to see clear, transparent water in a tropical lake. The fish loved it. Oxygen levels rose to 8 mg/L.

A nice fuzzy soda pop. The way the bubbles of a McDonald's Sprite tickle your 'buds.

Russell Wilson once claimed nanobubbles protect him from concussions. He's also a complete weirdo
