I work with ammonia solutions but never seen the solid stuff. Wow. It's a very practical subtance for its ability to complex with some metals in suitable oxidation state (zinc, silver).
This is really cool! A similar effect can be seen with N2O at atmospheric pressure, not under vacuum. As you blast a jet out of the small opening of canisters of a surface, solid N2O is formed!
Very interesting ! it may be really awesome to verify how to deal with a spill of ammonia in space conditions (temperatures are not the same there, radiations too ).
My favourite thing with liquid ammonia is the colour you get dissolving group one metals into it. I used sodium in liquid ammonia in Birch reductions. It was fun!
Is there some sort of charge build up effect from the spray? The tiny little 'machine gun' bits of ammonia seem to want to spray sideways rather than falling or shooting downwards. I'm reminded of how the water spray behaves in a 'kelvin' water drop' generator when the charge gets high enough. I've certainly heard of charge build up from steam jets...
Yeah the non-conductive nozzle also seems to point to Coulomb repulsion going on. If I were to hazard a guess, I'd say the synchrotron was being used to spectrographically analyse the electronic configuration and instantaneous charge distribution. I do not, however, think that the synchrotron is directly "kicking" the frozen ammonia off, as that just seems to be a totally bizarre amount of energy to transfer (although I suspect the real work would be supplied by whatever is charging up the ammonia in the first place). Either that or just something 'boring' like how subatomic nucleation initiates and propagates in a liquid->solid transition. Still, I really do want to know for sure...
can you please continue your ultrasound experiments? can you hold your thermocamera to the ultrasound water well? can you find out if ultrasound toothbrushes have any merit?
Choice magazine in Australia I seem to remember testing Electric toothbrushes. their conclusion was benefit was corelated with price. Meant to be the best clean you csn get outside of a dentist.
Yay, I suggested ammonia in his molecular modelling video. Great to see... How about HF Hydrogen Fluoride next! If you're not willing to be crazy (or awesome) methanol/ethanol hydrogen bonding would be interesting.... Or even mixtures such as acetone which can accept hydrogen bonds albeit not mske them by itself. Find us something cool with hydrogen fluoride.... just keep the calcium gluconate nearby
I used to work with ammonia in air conditioning. It just used to rot through everything. Funny I never needed to trim my nose hairs when I was working with ammonia
Nice video thunderfoot, I would have thought it would flash to a gas in a vacuum despite and cooling to the liquid. Maybe an auto refrigeration mechanism of sorts but backwards looking somehow. Sorry about the rambling, this is my 30th straight day of work.
Wait, so if I had gaseous ammonia in a container, and waited for a really bad winter day here, I could get it to liquefy just by going outside? That's kind of cool for some reason. It shouldn't be; different things have different phase temperatures, but you don't normally associate room-temperature-gas-going-liquid with, well... bearable outdoor conditions if you have a comfortable coat.
honestly? It is a bunch of junk stuck together with electrical tape. Ordering a custom version of this commercially would be buttload expensive, and it needs to be rapidly prototyped several times until they get what they need for the apparatus... Which may mean hundreds of different orders of the same thing. This is why "research" in "expensive labs" is expensive, because of this retarded money and paperwork. NASA do this kind of shit, and it's bad, it's why they're falling behind SpaceX.
What causes it to lose temperature so fast? Is it the lack of pressure? If the lack of pressure causes it to occupy more space then the total heat that it had is now spread across more volume, and thus it has less heat per unit of volume when it enters vacuum.
Evaporative cooling. It's the same effect that makes your body cool when you sweat. The phase change sucks up crazy amounts of energy for any substance with hydrogen bonds.
solid F2 under vacuum would be crazy xd .Other halogens and compounds that would be intresting are BrF5,ClF3,OF2,XeF2,XeF4,XeF6,KrF2(most powerful oxidiser ever) Stable under -78degC
@@faceplants2 So basically (theoretically) room temperature or close to zero C temperature water should freeze if purred in similar way into vacuum? That could also explain why water vapor condensates in upper atmosphere it isn't just that it is cold there but pressure there is lower also?
Don't lie that's a new pop rocks recipe
Would have some fizz in your mouth for sure.
the fuck
Thanks for the SHORT, INTERESTING video.

next add some stepper motors to the jet and 3d print in solid ammonia.
Excellent little curiosities! Keep them coming!
That's the coolest sand(ammonia)clock I've ever seen.
Best scientific observation of solid ammonia, "Niiii, it's kinda cute to watch".
More please, really interesting!

Ammonia is quite commonly used as a refrigerant with a code name R717.
Simply wonderful

Seriously cool!
(I'll get my coat...)
That’s why it makes such a good but deadly refrigerant.
Fascinating.
I wonder if the nozzle shape or nozzle material is responsible for some of this weirdness?

Dambit! We want more content!!!
Did you missuse an ion source for a mass scpec to do this?^^
Is there any place we can read that literature when it is published?
Why would anyone dislike? Not spectacular enough?
Vertical Video, is my guess
Have you tried adding gel agent and making it room temperature ?

Really expensive snow globe
How does this compare to ammonia in a cold air, hydrogen, or nitrogen atmosphere?
That first picture looks like you just found a bunch of junk and stuck it together with electrical tape ;)

how much does it expand from solid to gas (20°C)?
How about a video on the weird stuff liquid hydrogen does?
Did I just spot a hardware store type funnel on top of some really expensive stuff? :)

If you constantly draw the vaccum... where does the exhaust go??

An ammonia popcorn maker!
Looks like ammonia popcorns....
Next try reacting it with some things it normally reacts with while frozen under vacuum. A halogen may be best to use.

Did u refer to chunks of frozen ammonia as cute
Cool!
Seems like storing Hydrogen in liquid ammonia might be useful if you could extract the Hydrogen using a microjet
wat
Too bad you couldn't use a Phantom camera or something to watch the formation of solid ammonia in slow motion
It's BESSY II, isn't it?
Cool.
That is soo cool, and cool
I quite like ammonia, if you can tell.
Neat lil ammonia snowflakes😍
I'm trying to get a meth lab started, do you know where I can get some anhydrous ammonia?
Nothing a decent slomo won't explain. ;-)

Dumb question: How you get temperature change in vacuum, like -30c;-70c? As I understand vacuum by itself shouldn't conduct heat.
doesn't stop the liquid from having a temperature.
@@Muonium1 Then that means that that liquid should be at -30C or -70C from beginning?
The liquid going in was not under a vacuum originally. When you have changes in pressure and/or volume you get changes in temperature.
@@faceplants2 Oh that makes sense. Thanks.
@@faceplants2 So basically (theoretically) room temperature or close to zero C temperature water should freeze if purred in similar way into vacuum?

Wouldn't the cooling damage the vacuum
@Jay eS well in theory the metal would contract resulting in a smaller space, low pressure in a reduced container will be higher than when it started
@Jay eS if that pump is still running
@Jay eS nope
Do you actually get paid a wage to watch cool shit like this, or do you have to live on grants and other sources of funds?
