Any idea of scale? This looks like a microscope shot with typically some areas in focus, some not. If so: good shots!

Yeah it's a microscope shot. :)

It’s that cold in my lab right now: a frozen solution of 0.1 N KMnO4 in a burette. You’ve heard of permafrost, now you’ve seen permanganate frost!

You might want to invest in a small electric space heater. Just be sure your volatile flammables are carefully stored away!

Got one: in the current conditions it hardly makes a dent in it! We've had another 15 - 20 cm of snow overnight.

That must be crazily cold weather until that permanganate solution get freezed!:o

Well, at 0.1 N, the solution is only 0.02 M, so really quite dilute...

Very well shot. Do you also know what current you were running?

no idea, probably less than 10ma for the slow growth videos. Maybe in the future i'll do more precise growth with controlled conditions.

Yes, it must be a very low current for such slow growth. With an SnCl2 solution I got crystals of almost a cm long with 4 A in about 1 - 2 mins...

Nurdrage Could that crystal growth be done with different elements?
Could you give examples of ones that would work,thanks.

Here is a picture of me working up a fluorescein-type (resorcinol malein) synthesis. It's more a matter of removing all of the other crap from your product, rather than vice-versa. The yields are *that* bad. Fortunately, the precursors are cheap.

Anyhow, here is some of it on silica gel eluting out with a manual (EtOAc:Hexanes:Methanol) gradient.

This was taken with an Iphone 3GS and an El cheapo blacklight.

Cheers,

Hrm...in that case, the power source I'm using must be churning out a MUCH higher amperage than it is rated for...since it is also rated for 4A (no multimeter to check though).

Anyway, Sn crystal growth in real time:

Probably so, although i haven't tried any to say how good they will be. I'm told that tin works really well. from a solution of tin(II) chloride.

No, I don't really think so: your growth rate is about the same as mine, a little higher perhaps. Also: my electrode was much more compact and crystals grew in all directions (for the same amount of tin that makes for shorter, more compact crystals): I used a graphite electrode from one of the larger type batteries. I used a 12 V, max. 48 W rated DC source, so max. current 4 A.

I would love to have an opportunity to conduct some experiments at very low temperatures(-10C at least), but where I live it's about 30C in a cool day.
So, be glad you live in a very cold place!

Rightfully named Nurdrage, Teaser:D You gonna tell us how or just leave us hanging. Pretty cool. Someone should give there lady freind a glowing rose because if that don't say special I don't know what does.

actually it came off my latest video:

<object width="853" height="510"><param name="movie" value="http://www.youtube.com/v/2vhcHuaArdg?fs=1&amp;hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/2vhcHuaArdg?fs=1&amp;hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="853" height="510"></embed></object>

Nothing special really, just take a flower and stick it into highlighter fluid water and then shine a UV light on it after one day.

Safe and cool looking.
