A bismuth chloride solution precipitating on aluminum foil. I think that the depth of field came out nicely in this snap.
I plated a glass vial with silver via a Tollens reaction, then did what any sensible person would do: tossed that sucker in the microwave! After a few
seconds, this pattern, like an ant's nest, had appeared in the coating.
Ammonia complex of nickle oxalate, diffusing gracefully through some filter paper.

Some nice crystals of my compound under UV right after recrystallization.

Sorry I'm on my phone, as always. It's just very annoying.
Why not restrict the image in the bb tags?

I didn't think the Bohr model was this accurate.

Well, it's just a hydrogen atom. Look at pictures of the rest of the orbitals, it's pretty wacky.

The quality is not that great but here is a photo of a vial of freshly recrystalized copper tetramine nitrate.

That doesn't follow the Bohr model- if it did, there'd just be the outer ring, and nothing inside it. That's one of the s orbitals, with radial nodes
separating the outer ring from the stuff inside.
Please remember: "Filtrate" is not a verb.

Na2Cr2O7, i think this picture gets the red almost glowing flouroscent red this gives.. very deep and pretty
my favorite above all.. not only does it have incredibly many possibilities for one compound but its also pretty by itself
another CuCl2 picture, from my mobile phone
sorry if the pictures fills 10 times this page :S |
Are you using Coca Cola glasses to hold your CuCl2? I wouldn't drink from that again!

That is incredible! I have never seen anything like that. What other critters glow like that, if any?

I had no idea centipedes are UV fluorescent. Scorpions are known to be glowing, but centipedes... I remember illuminating them, but never saw any
glow. Maybe it's only a certain species that glows like this?
The photo is kind of creepy. I don't like those things much, and when they glow, it's like a horror SF.

Yeah I had never seen these things before. So I was pretty surprised and amazed when I saw them fluoresce. It seems there is something in their
exoskeleton that fluoresces, because I found small ring sections of dead centipedes that still gave off a blue glow under uv.

It's some kind of a protein(s) that fluoresce when being oxidized in a particular way. Fresh scorpion's cuticle is not UVA fluorescent. It takes some
time until it hardens. The oxidized protein (or oligopeptide perhaps?) is supposedly soluble in ethanol.
Interesting enough, scorpions give off cyan-greenish fluorescence, and this centipede is rather bluish.
Nice photos.

When I was 6 or so, I went with my dad on a trip to the southwest; he was friends with a biology professor who was studying the fluorescence of
scorpions. We would go out at night in the desert (Big Bend Nat'l Park) with handheld blacklights and look for the critters among the desert, which
was strewn with fluorite, glowing all colors. There was no light pollution or humidity either, so the sky was clear and full of stars. I still have a
jar of preserved specimens which fluoresces weakly. I'll see if I can dig it out and take a pic.
Had no idea about centipedes though, thanks for sharing!

How to know that your polyaromatic organic substance is in the etheral layer? Just use an UV lamp!

Dit you make that or did you buy it? (I've read many attempts to make fluorescent/phosphorescent samples from ZnS, but most of them didn't
work.)

TLC from a reaction I did few weeks ago (making some spiropyran derivative):
A bit blurry as it's in the chamber. Luckily the product could be precipitated out (faint orange spot above the big reddish one).
