I literally just cried. Chemistry is so beautiful it blows my mind
Fascinating, just fascinating. Elegant and simple, and certainly scalable! I hope you guys have had a lot of success with this system. I again regret not going further on into chemistry after high school, I would have LOVED to be doing this kind of thing. Sigh.
Follow your dreams kids, not what people think you would be good at.
Great Video, I love looking at novel new products. I did all my graduate research in supercritical water using it as an eluent for reverse phase chromatography. Was challenging as I was working in the capillary scale and the super heated water (400C, 12,000PSI) would dissolve the capillary after one run. Again, great work and thank you for sharing in such details.
The animations here look really neat
This was such a big help with my research paper!! Thank you soooo much. :)
Nice video Brady, I love the cq work helping explain the process.
Fascinating stuff! Thank you for posting videos like this one!
i love all the videos done at nottingham they make everything so easy to understand!
I was taught about it, too but never beyond "Okay, some weird stuff happens in this region. Let's not talk about that. Shit is cray."
@wel97459 hi, that is intentional... I often put a line I liked from somewhere in the video at the very start before the title... kind of like a preview! :)
@DeoMachina no, well beyond my skills... It was made for Professor Lester by a clever chemistry student who does a bit of CG on the side.
Wow. I'm impressed. And I haven't been impressed for about 10 years.
Very nice video. I'm a chemical engineer, so I'm somewhat familiar with the subject. Great to see these videos and what other people are doing around the world.
Interesting video, great CGI! :D Thanks once again Brady.
I loved the descriptions. This jacket thing here and space ship thing lol
It's amazing how many things nano particles are being used for. Was reading that they might use nanofibres in the future for making space elevator due to them being so strong. That in it's self for me if a great reason to pay a lot for more research into nano technology.
i got a bad grade once in school for answering the question if you could heat water to above 100 degrees c with yes. "right" answer being no, it would be steam. there was nothing said about atmospheric pressure. thats how life goes sometimes.
waldsteiger in education, one typically doesn't get any points for pointing out a flaw in the system. Generally questions are presented in a format where the context is assumed as if it's all some sort of vacuum.
What is the cost, to generate nano aluminum particles that are being sprayed on the People, in chemtrails ?
per pound ?
per ton ?
there's no such a thing as aluminium nanoparticles, as aluminium oxidizes in air to aluminium oxide. Any piece of aluminium in air forms a thin surface film of oxide, which is negligible in macroscopic applications but at the nanosize makes aluminium nanoparticles in air impossible.
Very impressive+interesting.
And a note to Notts' uni; hiring Mr Brady was a very smart move.
Such a cool video!
great video!
What software did you use to visualize the flow of metal salts through those tubes? And swagelok fittings for reactors? I think you just require counter current flow to achieve nanoparticles of the metal salt. Am I correct?
Nice pressure system! Where can I download the full version of the 3D animation? I haven't found any link to it on Promethean Particles website.
Your right about the starving and the 1% that needs to be sorted out now not in the future, but not at the expense of innovation. One of those innovations might be the way to feed everyone and supply all the food and resources needed. Like for example a space elevator will make it easy to get into space which makes it easier to get to all the available resources in say the asteroid fields as an example.
Thanks,...it is very interesting...

i feel like someone should implement the apparatus with natural shapes-- utilising natural organization. Water tends to swooping-arcs (in one direction, as needed for the process, just like the heater coil) , meanders, in nature... maybe there'd be a mite less need for the so-implemented "capping flow". to waste a lot less and make the process as efficient as possible.
Wow, I do hope Promethean Particles can stay in good regards with there investors, because this method of creating nanoparticles on a wide and industrial scale could help speed along progress in nanotechnology in general! Is there a limit to the types of particles the machine could make or could use any element you wanted?
There's a part in the video that repeats, near 2:45
Is the placement of the heating mechanism a result of reducing stress on the high pressure pump? Or would that be negligible?
How much does one of the spaceship shaped object typically cost?
cool engineering stuff
I like how he says football and not soccer ball. I'M TALKING TO YOU, U.S.
Brilliant! I wonder if you can slip-cast that artificial bone.
is there any relation between the photons in light and nanopartical
i wish you the best with your financing...
take good care and peaCe2U...
What is that "spaceship looking thing" ?
Especially the spaceship-looking thing
I'm curious: what software was used to create this CG?
wow, wow, wow, so fascinating!
Super critical water.. I was wondering if it is possible few days ago, because supercritical co2 has been used a lot in the labs. Because water is most abundant than co2. But I find your video.. nice guys..
How do you raise the pressure of the water to 200 bar and the temperature to 350 Celsius without a pressure vessel of some sort? I calculate that the pressure vessel for containing even a 25 ml portion of water at the critical point need some walls at least 8 cm thick to withstand the stress(stainless steel container).
Looks like your calculations are WAY off. It is not that high of pressure. Many SCUBA tanks are in the range. Countless hydraulic systems work in this range.
24680kong Funny how people are an expert at things they don't use.... I have serviced 200 bar accumulators that are very thin and never fail. Personally I'm not a fan of super high pressure. Know a guy who lost 2 fingers looking for a leak at Los Alamos. Said his fingers fell off and he just stared. Could not see the oil stream yet it sliced him.
@@tireballastserviceofflorid7771 Wait, i know about the water jet cutter but don't tell me these pressure vessels can turn into such a nightmare. Approximately what was the diameter of that oil stream? I'm wondering how he didn't see it.
Brits just can't resist a cup of tea reference.
Woah! Nifty CGI Brady! Did you make it?
Brady freaking rocks
I liked the CG
can nano particles move
Interesting, if composites and nanomaterials become more readily available and cheap to mass produce, it'll revolutionize modern engineering.
Strange that he says no one knows of supercritical fluids in undergrad. We were taught about the critical point and supercritical fluids in sophmore thermo. Perhaps my small little school in the U.S. was different.
My mechanical engineering masters degree was with this and direct sp. vol. equations (as a function of other parameters) especially with eutectic super/subcriticals that was back in the 80s. Wish we had nanoparticles to study then, I would have switched my major to chemistry.
He's talking about primary/secondary school. He says you won't see it on your GCSEs, that's General Certificate of Secondary Education. For ~15-16 year olds.
@ignilc You're absolutely right. There is enough food and water on this planet to keep all 6 billion of us on a 1600 calorie/day diet.
What is the spaceship shaped object's proper name?
+ruser0084 it's the pressure vessel you've been asking for :) no idea of its cost though
+PositiveANegative Thank you. Do you have any idea how to make a DIY pressure vessel？
I'm pretty sure it's a very bad idea to try and work to such pressures and temperatures without safe and testified equipment :)
It is a regulator not a pressure vessel.
That was a whole lot of big words my brain didn't understand.
no two bubbles are ever Identical / there's a thought
@Juxtaroberto But thousands of babies are born each day
We need nanomaterial! 1 day later. It's too small, we need to go bigger!
In the spirit of Red Dwarf... What a guy! I want to win lottery and donate it to charity and learn from this guy and id love to be able to call him when i need a kick to thought 🙏
Hey, we have been taught about supercritical water.
@FutureOfVideos And thousands of people die. Besides, newborn babies drink milk. If it's breast milk, you just need to make sure mom gets good nutrition.
@ignilc You could feed an entire family by selling your computer, and not having to pay for the electricity used. Why don't you?
Chemistry... it's like magic... only it's actually real XD
Low ,Energy, Nuclear, Reaction. 😆

Because I'm sure you'll get so much business from a youtube comment.
