Sonoluminescence using microwaves?

AI Thread Summary
The discussion explores the possibility of achieving sonoluminescence through electromagnetic waves, specifically microwaves, rather than traditional sound waves. It highlights the fundamental mechanism of sonoluminescence, where the collapse of a gas bubble is driven by the movement of surrounding atoms. The conversation raises questions about the differences in atomic interaction between sound and microwave radiation. Participants express uncertainty about the exact workings of sonoluminescence and whether microwaves could replicate the effect. The topic remains open for further exploration and experimentation.

Would it be possible to produce the same effect using electromagnetic waves instead of sound waves?
 
Science news on Phys.org
I'm not certain how sonoluminescence works exactly, or if anyone truly does, but I do know that microwaves have an effect on the atoms themselves, where the sound waves simply "move" atoms around. It is the the atoms pushing in around a gas bubble which cause its collapse which leads to the phenomenon.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
