My info could be wrong. My info is from my sister who has a PhD in bio-chemistry and has used electron microscopes for research. But that was 3 decades ago so maybe the technology has progressed.

Either way those images are quite attractive.

I think, but am not sure, that these objects are too small to have color. The contrast is man made.

Let's talk about some nanometers (in our Pipe of the Year thread):

Visible light is a narrow band of wavelengths from 400 nm to 700 nm. This means that the smallest thing we can see in a visible microscope would be a tiny purple sphere about 500 nm or so. For us to see it, a photon needs to be able to hit its entire wavelength on the object and bounce back.

If we want to look at a thing, we have to bounce it with wavelengths that are much smaller than the details we wish to examine.

An average coronavirus is only 125 nm in diameter. The little spikes are about 12 nm. So visible light (and any concept of "color") doesn't stand a chance of interacting with particles so small.

Electron microscopes have much smaller wavelengths, able to resolve details down to about 0.1nm.

Those cool pictures are artist renderings. Real electron micrographs are only pretty to scientists.

Sounds like there should be a coloring book for electron microscope scans... make it how you want.

I have that stem and bowl. It's a great combo, but I don't get why they call a straight-walled bowl a Dublin.

What they call the Algiers is what I think of as a Dublin:

I'd be happy with any of these bowls.

The Chimney makes for a good smoke, too.

There is only one solution.

One of each bowl.

Problem solved.

Love the idea. Don’t have one yet, either.

These are rare in the field, so to speak. Instant cool factor.

Cool. I know not much of SEM really, except that I occasionally would submit samples to the x-ray lab at work for SEM in combination with XRF. I wondered how they could sometimes give me images with colored renderings, I guess it helped with explanations sometimes, e.g., if a particle was white colored with Titanium present it was presumed to be part of a paint chip, etc. Anyway, my earlier comment was wrt SEM only, not viruses.

Oh, btw, those are some nice bowl shapes there.

I suggest that we get a smooth bowl and put the engraving on it. I don't think there is enough space on the stem to engrave.
