Pretty Pictures (2)

I know that these pictures have been posted, but for silver, I should reply with silver!




Something else: floating sodium balls in dioxane:

Here are a couple of my own:
Copper acetate, a copper salycilic acid complex (posted somewhere else aswell), a copper tetraamine complex and a steel bar I left in my forge a little to long

I shall also take this opportunity to once again complain about the image size limits

Potassium ferrioxalate

I´m new a newcomer here, so hope that I will not screw up anything with adding this post. Few weeks ago I was trying to make my own iron complex. This is the final product - potassium ferrioxalate. The size of the crystals is about 3-4 mm.

Very nice Hegi! How did you make your ferrioxalate? Welcome to science madness!

Hi, I used iron(III) chloride hexahydrate and potassium hydroxide to make iron(III) hydroxide, then i dissolved it in oxalic acid - this was solution A of ferric oxalate. Then I separately prepared solution B of potassium oxalate. I mixed it together, heated it up, partly evaporated the solvent (water) and let it crystallize overnight

Nice, you didn't use any hydrogen peroxide? lots of methods on the net use this to ensure the iron remains iron(III) and not iron(II).

I forgot to mention it, I added few drops of 33% H2O2

Maybe you´ll like this one too. 5 months growing copper(II) sulfate.

A really easy, but awesome looking experiment: dissolving some fluorescein isothiocyanate in water under UV light.

nice one man, what about exposure settings and used equipment?

Btw. This weekend I tried to make a crystal of ammonium iron(III) sulfate and it turned out to be beautifully and almost perfectly shaped.

Be careful, or some yellow powder will form on the cystal. Is the crystal really that brownish, or is that just due to lighting conditions? The one I once made was much like light coloured amethyst.

Keep it in a sealed container to prevent loss of water (<a href="https://en.wikipedia.org/wiki/Efflorescence" target="_blank">efflorescence</a> <img src="../scipics/_wiki.png" /> or lacquer the surface, as some mineral collectors do. What you have is a crystal of <a href="https://en.wikipedia.org/wiki/Ammonium_iron(II)_sulfate" target="_blank">ammonium iron(II) sulfate hexahydrate</a> <img src="../scipics/_wiki.png" />, the powder he mentions would be the anhydrous salt.

Vanillylidenacetone, from a micro synthesis, m.p. was ~123c, not bad! Pretty color



Edit: Crap... how do we re-size images? This is way too big.

I got this piece from a local solder manufacturer and it was cheap. These guys also do pewter alloys and use it for that, a good chance that solder companies in your area will have some for you. They might also have samples of Pb, Zn, Bi, Cd and Sn to offer you and their purity is good.

Half neutralized bromine water solution gives this beautiful color gradation effect.

Haloform reaction
(Iodoform)

Sublimated phthalimide in a large test tube, thought it was neat

***edit*** Looking at it now, it reminds me of a dark animal eye. Weird.

We just ran out of deuterated solvents for NMR, so we had to make some. Here is a "few" ampules of mixed deuterochloroform/deuteromethanol with a little added tetramethylsilane for NMR spectroscopy.

Simply sodium chloride crystal grown on a stone.

The iodoform is really cool looking. It reminds me of lead iodide which I just made. I have so many beautiful compounds and elements. I wish I had a camera.

Some nickel/copper acetate I made

Very nice! Careful handling those nickel compounds, though!

Just another day at the office...

I *think* that on the left is triethylamine, then sulfur trioxide (something..) complex and dimethyl sulfoxide. Might be wrong but I wanted to take a guess lol. I wish my job was like that

(Edit: is the one in the middle sulfur trioxide-pyridine complex?)

[Edited on 19-10-2013 by Mailinmypocket]

Yep, mailinmypocket got it. I was doing a Parikh-Doering oxidation (non-cryogenic version of Swern, ideal for scale up). Input material was 1.4kg alcohol substrate in each flask (the upper picture shows the workup of the reaction, which took 3 days in total). These pics were taken a few months back, but that was 2 batches of 12 required for the custom manufacture campaign. Unfortunately the smell ofdimethyl sulfide byproduct progresses throughout the next three manufacturing steps.

They're 20L rbfs btw ;p Also note how we don't shake the sep funnels at that scale. They remain stationary... The phases are mixed in the reaction pot, transferred to the funnel by vacuum line and separated. Organic gets sucked/poured back into the pot and washed with the next solution.

Just another picture to keep people happy... Again in a 20L pot, equipped with a 2L addition funnel full of acid chloride solution. It feels quite funny looking at these pictures now because I'm currently working on microscale reactions.

copper acetylsalicylate

Some nice crystals which formed at the bottom a flask.

It was a polymethoxy furane deriative what formed as a side product of a reaction, but it will be really useful for me in the future.

thanks, I will also post a picture of bis(oxalato)cuprate(II) tetrahydrate

I love my tritium keychain! Maybe not "pretty" but really neat to always see the thing glowing after almost 8 years

To satisfy large demands from the Vatican I decided to make isopropyl nitrite


the bottom layer is really cool it looks alive and rippling
Shortly after this my stirring failed due to the Na2SO4 slush

I am really preparing this in preparation to distilling HCN as an antidote, just in case...

[Edited on 30-10-2013 by Pyro]

Talking large scale? Talking hundred liters



Edit: Sorry it's not very pretty.

It was not my reaction, but: something crystallized from the mother liquor of an aromatic alkyl imidate and it looked great, just like on the pictures. Organic crystals are awesome!









Have You seen my portfolio? It’s over here: http://labphoto.tumblr.com/tagged/portfolio

This was an attempt to grow crystals of copper(II) anthranilate by allowing methyl anthranilate to hydrolyse slowly in a solution of copper(II) acetate in 50% aqueous acetic acid. They look more like copper(II) acetate to me, and seem to be somewhat soluble (which copper(II) anthranilate isn't). So I'll chalk that up as a failure, along with the attempt to hook the microscope up to the computer so that I could get a picture without resorting to an iPhone.

A nice shot of a crystal of naphthalene growing on the end of a thermometer.

Cheers,

O3

sodium sulfate crystals, sadly they started showing white spots after a few hours

Copper(II) acetate

6 weeks growing crystal

Pumping down an air sensitive ligand:



A few mg of the the same ligand coordinating iron (II) ready to go for NMR, it is hard to tell from the picture but it is very very purple.

<del>Sorry about the link</del>
Erythritol recrystallization from Truvia sweetener, the black and red chunks are from an oven mitt I was wearing when dissolving the Truvia, they pose no threat to the erythritol or ETN synthesis because they're totally insoluble. Largest crystal looked to be a little over an inch, I'll weigh them when they're dry. Shot on an iPhone 4S but I can get better photos later.

Some Potassium dichromate I made from Chromium(III)oxide and Potassium nitrate. That is the unfiltered product with some unreacted oxide on the bottom.

Two images from my fun times with my buddy's DSLR:

Giant images - Enjoy this link
http://imgur.com/OdxIrgw,x3ACKvM#0

First is a 30-second exposure of Am241 modules under a silver-activated screen. Screen is about 1.5" across. 1-second light painting to pick up the rest of the image.

Second image is a 10 second exposure of a Tritium glass vial, with the phosphor coating. Resting material is white cotton, length about 6".

In keeping with the spirit of the Tritium pictures here is my small sample, used on my periodic table display, since it is my favorite isotope of Hydrogen.





And here is a recent element addition that's quite beautiful, a very large sample of Zirconium metal.

That Zirconium looks nice Would love to have that in my collection.

Some Chromium(II)chloride that has absorbed so much water that it's nearly impossible to cruch the chuncks. I think it's time for a new bottle
But still a beautiful green when you look inside the bottle.
http://i.imgur.com/b0mkGL8.jpg

Some Dimethylglyoxime with [Ni(NH₃)₄]²⁺
The upper layer is the Ni-DADO and the purple layer below the Ammonia-Complex. ( For some reason the image is flipped, I don't know why )
http://i.imgur.com/FbJwxKn.jpg

That orange stuff is a Cobalt(III) solution. Unfortunately I forgot how I made it. ( Image flipped,too )
http://i.imgur.com/zl4TgN6.jpg

Last picture is some Bromohexane...well it was supposed to be that. I made it by reacting Bromine with Hexane. Some weeks later these black dots appeared and formed a dark layer. It also started to smell quite stange. Must be some side product or contamination.
http://i.imgur.com/1nFtQ2U.jpg

I will upload more colored coordination compounds soon. And sorry for the image flipping. I will try to correct it.

Terbium piece

I got 5.7 grams of terbium for a science project. I took this with my phone which has a really good macro setting.
The sample is graphite-gray and darker than I expected. Probably some oxide contamination.
Grid size is ¼" per square.

fluorescence: That chromium chloride looks appetizing...

Dopachrome

Fluorescence, terbium is not very reactive towards dry air and doesn't seem to corrode, especially not in my location's dry air. See Dave Hamric's lanthanide corrosion test. It's mostly the rare earths from lanthanum to europium that corrode quickly. Also the terbium looks dark because I couldn't get good lighting. But it's not as bright as seen in some pictures. Terbium(III,IV) oxide is black like manganese dioxide and a little oxide makes it turn very dark.

Terbium costs $32/5g where I got it. This is the only reasonable place to buy terbium, even for laboratories. At Sigma and other suppliers it costs about $500/1g.

And to keep with the thread, here is dopachrome formed by the addition of tyrosinase (sourced from mushrooms) to levodopa.

I want that zirconium! It's wonderful! But, seriously though, rhenium, tantalum and molybdenum are so much better hahaha

EDIT: Back to the real world, I do not own Re, Ta nor Mo...

Just got a position in a lab at my university. I grow cells... Zombie cells! >
They are cancerous brain cells from a man.
This is Zoomed in, taken at 10x

This is a full shot of my favorite image. Well its just a thumbnail of a 2.4gb image.

Wasn't sure If I had posted my rats, so here are some rats in a jar

Formation of Elemental Sodium by Electrolysis Into an Incandescent Lightbulb

Not exactly original, but it's one of the most showy and blinding preparations I've seen in my time at the bench.

Some vacuum distilled phenol crystals in a 50ml RBF. These were prepared by decarboxylating salicylic acid. I am working on trying to boost the yield. It currently stands at 57%

Thank you.

The lights were actually on in the room, but of course the camera tries to balance the image against the brightest source in the shot. When that's an incandescing filament, everything else is dark. I rather liked the eery effect though, so I didn't do anything to try to fix it.

Will you be making a video of this? I would really like to see it

From right to left: the hydrogen comes in, bubbles through the flask and the reaction mixture, the reagent is added slowly to the mixture from the top placed addition funnel and the hydrogen what didn’t reacts exits at the left side through a bubbler.

Sadly it overreacted even with these mild conditions and I didn’t get the product what I needed):

Making some water free KOH by melting and boiling it out in a silver pot. It is ready when it stops boiling.

Care should be taken while working with it, especially when it's molten

Kristof, your pictures are amazing. What were you trying to make?

I'll try to compete with my more modest photos:

1. Terbium, after a real beating. It's a lot shinier on the inside. Wikipedia says it's soft, but doesn't say it's ridiculously durable.
2. Bismuth stairs.



Edit: Kristof, I was referring to your post with the hydrogen apparatus.

For the hydrogenation we tried to make a 1,1 disubstitued hydrazine from a nitroso coumpound (both quite toxic...). Sadly the N-N bond broke and I got back the disubstitued amine and some ammonia.

For the molten KOH, we needed something to distill from ethylamine, since we opened a few cylinders of it, what were stored for a few years. It was great to distill 2-5 liters of this gas, everything smelled like fish, even since it was under a fume hood

A very all day compound: K2SO4

The individual crystals making up this cluster are about 1 cm long.

definitely would be scared to do this thing... but anyway, very interesting

some beautiful uranophane crystals posted by kristofvagyok in the uranium thead.

m-dinitrobenzene




smells a bit like almonds, but more like marzipan. in the spirit of Christmas

A biphasic highly fluorescent oil under UV light, containing some substitued coumarine what I made a few day ago.

One of your best photos, kristof.

New element sample Probably only a few mg

Tried the oxidation of paracetamol to p-benzoquinone with aqua regia. The appearance looks good but this afternoons melting point will give a better idea of how the reaction turned out, looks nice though

Not chemistry related, but pretty nonetheless. The panorama feature on my camera is useful for capturing such phenomena.



I wish I could upload the monster 2800x1440 full size photo.

Bonus: Is it a solar halo, or a street lamp at 1.21 gigawatts?

Hydrolysis of ASA to yield SA gave some nice crystals: ( 95% yield too )


Some ethyl acetate from non-acetone nail polish remover.

Bismuth trioxide thermite, a series of explosions that happened in a short amount of time

I don't have the best camera. I was inspired by other photo's, so I thought let's try it myself.

GFP expressing E. coli

Not the best quality picture ever, but showing clear fluorescence though.

This is a 50 ml tube with a pellet of E. coli expressing green fluorescent protein (GFP) above a UV lamp. The picture is taken through a filter, filtering the UV/blue light, but not the green light.

Some pretty pictures

Here is an old photo I found when I stained a nematode with methylene blue (which stains acid regions like proteins and nucleic acids)
Notice the flagella which help nematodes move.

Some trimethylsilyl acetylene’s silver salt just when it was ignited.
