Preety pictures: OC edition
Freshly recrystallized benzoic acid
>>8169699
While we're on the theme of recrystallization, here's some sulfur
>>8169711
Well with the benzoic acid I used water and for the sulfur I used toluene (but xylenes would also work)
>>8169705
A macro shot of recrystallized acetylsalicylic acid
>>8169714
So is the sulfur reacting with the toluene to form a new compound then? Is it ionic?
>>8169813
sulfur dissolves in toluene
>>8169813
Actually the point of recrystallization is that it dissolves in a liquid when it's hot, but when it's cold it "drops" out of solution as needle like crystals. Doug's lab has a great video about it! https://www.youtube.com/watch?v=lmFga5kwNZg
>>8169826
Thanks, senpai.

A little bit of DIY chemistry:
Seperation of the aqueous and organic layer (which had mostly mixed mono-nitro toluenes in it)
crystallization in orgo lab was fun the one time I got actual yield
>>8169699
cool i watch dougslab too
>>8169978
>crystallization in orgo lab
or should i say 'how to flush your product down the toilet 101'
>>8169699
is that drugs?
>>8169973
Sone preety KMnO4 crystals
>>8171551
Are those mushrooms?
>>8171512
is it bad that i want to sniff those things? they look tasty.
>>8172153
Well it has an LD of around 1g/1kg of body weight so i guess you could get away with snorting up a few lines haha
>>8172153
You could, but every time you sneeze for the next decade you'll leave a bright pink mist in the air.
>>8169973
>(which had mostly mixed mono-nitro toluenes in it)
How were you limiting the nitro addition if you don't mind me asking? I always though that adding nitrate salts or nitric acid pretty much just turned toluene into TNT relatively quickly.
>>8173025
No, not at all. To make TNT one has to have very harsh conditions (eg heating, fuming nitric acid, multiple addition steps, etc.). And I tried to limit it just to mono by having the temperature always below 15*C
Not OC, but it's still very pretty
Neodymium Sulfate crystals
>>8171512
In Russia we have that in free trade.
>>8174418
how do you make magnets out of them?
>>8172146
yeah, but I've yet to identify them
>>8174796
ok i think it is "polyporus (piptoporus) betulinus" or birch bracket
>>8172146
They look like feral marshmellows.
>>8171512
Kay, mang.
>>8175487
Are they anything special? Can one eat them?
>>8171512
Another picture of benzoic acid. Wierdly, it didn't form needle like crystals but rather shapes like a typical snowflake. The only thing that changed was that I did it in a wine glass. Will do more reserch on how the shape of the container affects the shape of the crystals.
Silver staining. Guess the yeast

What is it indeed?
Individual cells of an onion peel
Wow. I hope you guys die from this.
ITT op's meth lab
cross-section of silicon (SEM).
SEM picture of a fatigue failure on a steel pedal
Same pedal, but brittle part of the failure IIRC
>>8179313
I only got a few of them, checking my assignment folder.
Got some pretty aesthetic insect SEM OC too :)
Fly leg SEM
Fly wing SEM :)
>>8179313
Here you go
>>8179341
Last material failure one :(
>>8179345
Vicker's crack on a random ceramic :)
>>8179310
This image is not a brittle fracture surface it is ductile failure indicated by the micropores
>>8179304
This image shows a typical cleavage fracture surface and no indication of fatigue failure
>>8179328

>No scale bars
Something old, like 6 years old

>magnets
"Neodymium" magnets, oddly enough, are mostly iron. The common formula is [math]NdFe_{14}B_{2}[/math].
>Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
>>8169699
Are engineers welcome here too?
>>8179388
nerd
OC Fractals also allowed?
>>8185100
>Fractals
OP here; They look amazing! How did you make them?
>>8185104
in mandelbrot you dummy
Zn-Al die cast alloy microstructure. Ignore the labeling, it's a bit dumb.
There's some micropores due to shrinkage maybe, as well as a scratch cause I didn't polish it perfectly. You can also see the individual grains and contrast between phases.

Here's a piece of steel (left) covered with paint (middle) set in bakelite (right)
>>8185172
Here's a Zootoca vivipara, or common lizard. Took this last week-ish.

Here's a robin.
Not OC: Crystals of antimony trichloride left in a flask after a Swarts reaction

wicked bong
lysozyme crystals
>>8187781
These are so pretty! How did you get them? Did you extract them?
>>8187781
orthorhombic structure is beautiful
I forget what it is, was some time ago
>>8185132
Actually I wrote my own renderer!
>>8185104
With my own renderer! That one is a transformed Menger Sponge. Here's another
>>8189621
Another one
>>8189633
And another
And ofcours the normal Menger Sponge
Transformed to shit, was made to test shadows
>>8189621
Good shit anon.
Is your render software available?
>>8189657
More than just available! You can render them yourself within your internet browser! https://www.shadertoy.com/view/lttGzr

C. ablicans?
>>8189662
Oh boy, thats really fucking neat, thanks.
Bookmarked it. Will probably spend half the night dicking around with it, kek
>>8189685
I suggest changing only the following variables :
CameraPosition (Camera will automatically look at the origin)
Scale (Relative scale of the fractal on every iteration)
Iterations (not too high or you'll crash)
Offset (Scaling transformation)
m (Rotation transformation matrix)
