Chemical rope trick 3
Переглядів 165 місяців тому
This video shows the evolution of a coiled chemical garden tube that formed in a weak density gradient of the surrounding solution. The 3D shape of the tube was analyzed by in-house MATLAB scripts using video data. These structures grow in response to the injection of a solution containing Mn2 and Cu2 ions into a sodium silicate solution. For more information on the experiment watch ua-cam.com/...

Timelapse movie of a green Ni(OH)2 membrane that grew in a horizontally positioned microfluidic channel. The left frames come directly from optical microscopy; the right ones are image-processed copies where an intensity threshold was applied to emphasize change. The big upper and small lower gray bands are NiCl2 and NaOH solutions. In this time-lapse video, both solution flows are suddenly sto...
Chemical Garden Simulations
Переглядів 142Рік тому
Video summary of the dynamics in our cellular automaton model of two-dimensional chemical gardens. Each cell is occupied by either reactant A (gray), B (blue), or the solid product C (color depending on age). The basic idea is that the expansion of the pattern occurs mainly in the newly formed C regions (gold), not in the old ones (black). The strength of this stochastic preference (log k) dete...
Biomorph meets polymer disk
Переглядів 612 роки тому
This is not your usual crystal growth. A biomorph sheet meets an elastomer disk, converts into fibrous bundles, and then starts to push and flip the disk. Biomorphs are life-like polycrystalline assemblies of BaCO3 and silica. They grow in aqueous solutions of BaCl2 and Na2SiO3 when CO2 from the air slowly enters the systems. The disk is made of PDMS (polydimethylsiloxane) and was part of a lar...
Bubble-driven micro-comet
Переглядів 1882 роки тому
A tiny catalytic tube creates these comet-like bubble rafts when H2O2 solution is broken down to oxygen bubbles and water. The resulting life-like effects occur only if a soapy substance (the surfactant AOT) is added to the solution. The tube self-propels through the solution by rapid ejection of bubbles (like a microrocket) and is barely visible as a small black line near the tip of the foam f...
Chemical Garden Swarm
Переглядів 1972 роки тому
Collective behavior in swarms of self-propelled chemical garden tubes. These catalytic microrockets produce and eject tiny oxygen bubbles. The video shows the tube motion in real time. The chemical gardens are grown by injecting MnCl2 (and CuSO4) solution into a sodium silicate solution. It is an interesting challenge for chemists and engineers to capture/mimic some of the complexity of swarmin...

1,4-Cyclohexanedione Belousov-Zhabotinsky Reaction
so pretty
In the published paper it looks like the setup includes 4 screws on the corners to seal the device. Are those necessary?
Maybe the best BZ reaction I’ve seen. This is quite often a visual overlay that I’ve witnessed during some psychedelic experiences.
where did you purchase the barb fittings?
by now we are using cut pipette tips which work as well and are cheaper (the original supplier of the barb fittings was Cole-Parmer)
It's so useful, can I have a look at the code? Thank you.

I like the spirals, normally you just see concentric rings. I'm waiting for some ferroin to arrive so I can do this reaction.
They will also grow downward from the surface of a liquid especially if the metal salt is heavy. Uranyl chloride is best to demo this as grows downward tubes readily. However, the uranyl chloride solution is so dense that upward growing filaments take a long time to grow and are very short.
Absolutely beautiful
Uzumaki infestation
Yall too high
So cool
how much quantity do we need to mix?
Thank you for sharing this. At the end of the video I can't understand why the flow in the channel is like a very thin line?!
Two solutions are co-flowing along the channel. Along their interface a thin precipitate membrane grows.
@@SteinbockGroup Thanks a lot. Could I ask other questions: At the outlet how do you separate precipitation from unreacted precursor solutions? And a micromixer is different from a microfluidic device?
Hypnotizing! Made my wife sick tho...
I'm guessing they use spiral cone DNA or cyclone DNA in the future to compute The matrix and to create us which are bio AI.
I think we are bio-ai in a matrix living in the simulation year of 2022.. when i think we probably actually live closer to 2500 in base reality.
Craaaaaazy
One of the cooler ones online thanks
What God has created boogles the mind. So beautiful. Man wants to mimic the strength this Venus Flower Basket Sponge displays to create stronger objects to benefit man.
Hi, I really liked you video. I am working on microfluidic channel, and I would like to ask you about the slides you used and the machine from which you cut the parafilm. Can you please provide more details of the cutter, how thin can it cut?
Cab u give a detailed written procedure with exact amount
Look at the DOI link in the description, it's free access
Hello, which machine did you used for cutting the parafilm?
Hi Material 1527, the link is at the bottom of the video description.
I predict a lot of people won't understand this video and will along of the years get it recommended randomly so if you're interested check the description and go look about this BZ solution. Amazing that there's no fluid motion and the waving pattern is created because of a kind of chain reaction.
This is so cool.
Huh best but most random video ever
I'll be the first to say that I'm here from a Veritassium video.
Here from Veritasium too lol.
Too

@@SteinbockGroup Thank you so much!!!, greetings from Peru.
I tried it. It worked well. Thanks!
Can a similar setup be used in reverse? For splitting/separating?
You can separate by size but separating a precipitated molecule into its previous components is not possible unless you do it chemically
Great !
Very Nice!
it’s crazy
what the hell is that guys??? it looks freaky amazing

I’m not an expert in chemistry but your reaction seems to be different from the normal oscillating reaction. It does not form ripples but instead forms spirals. Does this indicate that your reaction has “directionality” or polarity? If it does is it slightly different from the original reaction?
Yes.
All the chemical elements in our world have polarity...it's the force that drives creation in fysiology, physics and chemistry...all matter has here one atomic number of proton neutron electrons equaly present. Without them interacting and bonding nothing gets created or functions.
Hello from the future! When the rings are damaged during formation, it causes a continues spiral like formation. This can be done many different ways, but the easiest is to just blow on it.
@@chasecollins3263I thought this. I'm waiting for some ferroin indicator so I can try it
And with only 3 bubbles, amazing.
:O The colors and shapes are quite unreal.
Bob from the Micro-fossil Gazette says: "Oh crud...".
The New York Times says: "A Truly crystallizing experience" The Chicago Tribune says: "At the end, we were not sure what is alive and what is not!" Nature Chemistry says: "Some scenes were missing error bars"
Fantastic !! This is mind boggling! Looking forward to many more such awesome videos from the Steinbock Group!
Nice video! This is an invitation to everyone or anyone to see an artist theory on the physics of light and time! This theory is based on two postulates 1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!
Ah, clearer now, thanks.
Can you provide a description?
thx
And what is normal dispersion? Just concentric circles? And why is this called anomalous? And why some oscillating system are anomalous and some not?
Yes. This is amazing. Sounds like really simple rules. Does it repeat forever?
