"Cheap things like printer toner"

Me: *needs to sleep* My brain: NO watch the CHEMISTRY MAN

Just wanted to say, the FerroFluid wrapping down the screw was one of the most relaxing things to watch.

Damn, catalyst must have studied this video for years.

This venom trailer looks awesome

2:47 pause gentely jiggle your screen and it will appear to move

“Pierce through the mundane”

This channel really opened my eyes to how fun chemistry can be, if only schools did these kind of experiments from time to time

I don't think enough people tell you how professional and high quality your content is

"Unsuccessful" experiments are just as important as the other kind. They should also be published.

Who else got this recommend to them after season 15 of apex?

So that’s where my missing canisters went

"H2O is water" is the smartest thing i can say in chemical

"I definitely added way too much kerosene" **Ten seconds later** "So I'm just slowly adding more kerosene" **0.2 seconds after** "I think I used too much kerosene"

Catalyst definitely watched this video

OMG! THIS PERSON HAS LEAKED CATALYST SKILL 4 YEARS AGO! WHAT AN INSIDER

Lisa Simpson's hair is ferrofluid and her skull is a magnet edit: i dont remember making this comment and i hate it just as much as you do

If you're watching on mobile, pause the video at 2:39 and slightly jiggle your phone back and forth.

Pierce their hearts! And their feet -somebody who is from Peak Myths or something

Catalyst saw this shit and started plotting💀

I think this is why I love your channel, you're willing to show everything, even your failures or mistakes. Most science channels only ever seem to show a perfect product, but you offer an insight into the problem solving process whenever something goes wrong, and explain your thought process when figuring out what went wrong, why, and how to fix it. The problem solving is just as much a part of science as the "cool stuff" is.

No amount of training can prepare you for using the right beaker size ❤️

10:35 his gloves stuck at under the magnet xD

Some tips from someone who have made a lot of magnetite nanoparticles in the past. 1. How pure the iron salts are can have a big impact on nucleation and there for particle size. The time the solutions spend in air will affect oxidation and hydrate complex formation. I always used chloride of both Fe II and III, never tried sulphate 2. Temperature during precipitation is important, colder is usually better based on experience and transmission electron microscopy (TEM) analysis. 3. Do not dry the particles fully, try and make solvent exchange, this will prevent aggregation. For example: water - acetone - toluene - kerosene (perhaps there are better routes, I have not done this myself, also I am not sure what is most compatible with kerosene) 4. Ultra-sonic treatment is often mandatory for good dispersion. Good luck :)

Try evaporating the kerosene away until it spikes. Also, the brown color may not be from contamination but rather the particle size. Nano particles have different optical properties from macro scale particles.

this definitely only showed up on my feed because the new apex character

This is so interesting, can’t wait to see further progress

This was by far the best episode of Full Metal Alchemist

I need to get my ears checked. You said “hard drives and speakers” and I heard “hard drugs and sneakers” and was intrigued

i don't know anything about chemistry, and i never understand what u do. but it's always so incredibly interesting just seeing everything react with each other and you doing stuff and trying to explain it to my tiny brain. well done dude.

NileRed: "It looks like magic" Me: "I think that is Venom"

Clicked because I thought it was a 3D render (tutorial), stayed for science

ALWAYS PUBLISH YOUR FAILURES! Very happy see this! 😊

This showed up in my recommended feed right after I watched the Apex Season 15 trailer

0:48 the forbidden blackberry fruit snack

I don't mean to sound like a know-it-all because I have no clue but do you think the stir bar you have may have had an adverse reaction as far as the magnetic movement

Actually admits early on and confirms this is an attempt and failed as to prevent any possible clickbait. You my friend are better then a large majority of KZfaqrs , also very entertaining!

Catalyst's favorite KZfaq video

daamn apex science moment

Never worry about showing failed attempts , tbh its more interesting and people would prob learn more

2:39 if you’re watching on your phone shake it lightly while staring at the powder

It's awesome to see someone that actually trys

Never gets old watching.

In high school I was really enthusiastic for Chemistry and pretty good at it too, a chemistry degree was my second choice. Watching your videos (not this one in particular) makes me recall why I was so enthusiastic and makes me want to do some chemistry again! :D

Nothing is better than a nice calm educative NileRed video at the end of the day

i listen to this dude and learn nothing but still enjoy it

Ferrofluid: *exists* apex legends fans: catalyst

9:10 "Mr Stark i don't feel so good" times 100.

Hey, have you got my mail about this topic? -Add the iron solution (1.5M) to the ammonia, not the otherway around. The fallout should be blacker than yours. -don´t pull out the magnetite straight from the solution, it will clump up. Instead add your oleic acid, about 5ml per 30ml of iron solution and bring it up to 80°C. ( I use Fe(II)Cl und Fe(III)Cl, I never tried the sulfates.) I never got the magnetite crash out by itself, I usally disolve it in petroleum, seperate the phases and crash it out with acetone from the petroleum. Everything left in the water is thrown away, because these particles aren´t coated enough. After crashing them out with acetone and a magnet, I redisolve it in petroleum (or n-Hexan/ n-Heptane). After this you should see small spiked when placing a magnet benath it. Then you have to supersatured the solution by letting it sit in the sun, or a another soft heat source for 2 weeks. It will thicken up and some bigger particles will fall out of solution. 13:15 this guy actualy gave me the idea of using acetone. 17:19 the color of your particles is way of, check the quality of your starting reagents. 19:10 spiking only acours when the solution is highly concentrated.

6:16 ‘forbidden coffee’ 😁

Nevermind pausing it. Just screenshot it. Truly mindboggling. What type of wizardry is this.?? NileRed you sir are dabbling in black magic.

1:28 "Cheap things like printer toner" made me laugh uncontrollably

From what I know about pigment science, your problem isn't "filtering" particles that are too big or not coated. Your problem in the criticality of milling your particles. Milling after mixing with oleic acid should both reduce particle size, and force the lipids to bind. Unfortunately, milling is also a seriously tedious process, and often introduces contaminants in the form of grit. But it is a noble task, and I think it may be worth that effort.

This getting recommended again cause of Apex

Foiler fluid made me chill its so satisfying

Some things to consider: 1) In general nanomaterial synthesis, the surfactants are included in the reaction mixture during nanoparticle formation to stabilize the particles and restrict their growth. 2) For a ferrofluid to work you must produce superparamagnetic magnetite, which means the particles size should be on the order of 20 nm or less. 3) Though aqueous precipitation methods are common, you have less control over particle size. One way around this is to first form the organometallic complexes (Fe-oleates) and then proceed with the nanoparticle formation (though these are typically high temperature reactions), the particles will form while maintaining a complete oleate coverage on each particle and remain very small and highly crystalline which will improve the yield of superparamagnetic particles with a high magnetic susceptibility. 3) The color changes from black-brown-black during your purifications are (imo) most likely due to aggregation in the various solvents as the overall diameter of the aggregate changes so will the color and the rate of separation. Note that oxidation of the magnetite over time (especially in aqueous solvents) will lighten the material to a lighter brown over time and iron species at the surface will dissolve into solution which can eventually desorb your surfactant and destabilize the material. 4) You may wish to degass your aqueous reaction mixture to reduce oxidation. As others pointed out: 1) Sonication! it's something I could not live without when it comes to nanochemistry (can get a jewelry cleaner pretty cheap and should work just fine for most uses). 2) >98% purity iron salt hydrates are pretty cheap, try and get some. 3) NaOH can be used if you don't need the ammonia-oleate reaction. 4) In many cases, the faster nucleation takes place, the smaller and more uniform your particles should be. 5) Magnetic stir bars will not adversely affect your reaction as long as you particles remain small and stable enough (as you correctly state they will not separate because their solubility is greater than the magnetic attraction force), however, if your reaction mixture is too large, mixing can become a problem and stir bars typically will not compete with a good overhead stirrer. Anyways, great to see you covering some nanochemistry and a room temp benchtop method as well! Good luck!

Youre video got featured on a Daily dose of Internet Video! I'm so happy.

I find it sooo soothing to watch 😁🥰

*Catalyst has entered the chat*

Well, now we know why it's so expensive...

Can’t wait for the next batch!!

I guess the new Apex Legends season must’ve brought me here

What a gr8 video!!!!!! I loved the where he said: "IT IS NILEREDDING TIME!!!!!"

Hey NileRed, love your Videos - you'll probably not read this because I'm late to the party but: If you're worried that the Magnetite oxidizes too much while stirring, you could try to do that process under a non-reactive heavy gas. You'll need to prevent excessive spillage of the gas but you'd rule out oxidation.

somehow i always make my way here when im baked.

I'd love to see a part 2 if it's still a project your working on

This reminds me of the movie Splinter with how it moves and looks, it's pretty neat!

Hallo Nile. The reason for your Brown colour is that you have a lot of rust in it. I had the same problem at university. After you produce your nanopartikel, you need to was them with water and enthanol. Then dry them and do the step with oil acid at the next Day. Then you can take the particels and suspend them in Olive oil. If you want, you can take a soap Solution and put the suspension inside. Then you can get a very nice ferrofluid :)

Hey I know this isn't the type of thing you normally do, but can you look into doing a video on alkalides? They're salts where the anion is a negatively charged alkali metal. I first heard of them a few days ago and looking at the procedure for their synthesis, it seems really interesting, though fairly expensive. Plus I haven't found any videos on them anywhere on KZfaq, so it could be a neat thing to show off

Man, you would be the best science teacher ever.

I love how he always sounds confused or unknowingly

Nile red and elemental maker posted videos within minutes of each-other? BEST DAY EVER!!!

it makes me feel better about trying things knowing that even the people i look up to make mistakes sometimes

Love how this is now trending cuz of apex

This was so awesome, I'm going to go ahead and watch something Ive always wondered about... The Myths of Iodine.

3:44 Forbidden orange juice

Him: it really isn’t that complicated Me: *aRe yOu SuRe AbOuT ThAt?!*

That bolt thread clip was pretty Frickin neat 👀

This popped up on my KZfaq recommended.... I like it and it’s very interesting. I’m subscribing

Hey, I did research on magnetite nanoparticles. In my opinion, the brown thing you get is most likely iron (iii) oxide due to the rapid oxidation under air. Perhaps you can try to do the reaction under an inert atmosphere. Otherwise, play with the ratio, and because iron (ii) will be oxidized, you can try to add more iron (ii). Another suggestion that may be useful is to use charged surfactant as tetramethylammonium hydroxide, and do the coating process under sonicator rather than stirring. It helps to break down the aggregates better than stirring. Good luck!

No one: Absolutely no one: Not a single person: My KZfaq recommendations, at 3 am: Attemptimg To Make Ferrofluid

2:39 this powder is creating an illusion that it's slightly moving but it's not (pause the video)

Woah!!...that was soo cool!👍

Well at least you tried good job! 👍😀

YES KZfaq IS BACK UP!

High quality info

This gut took my chemistry grades from f to a+.Thanks man

0:21 So Satisfying

“Mom, can we make ferrofluid?” “We have ferrofluid at home.” The ferrofluid at home: 1:28

Sure thing Magicman! :D I too have the "stable suspension of magnetaite nanoParticles" , often!

4:24 certified breaking bad moment

8:20 when you add oleic acid, overall volume of the fluid noticeably decreases. which's interesting.

2:43 Keep the screen paused and shake your phone. The ferro magnetism is not limited to in person interactions. O.o

16:07 looks like him pouring coffee ☕ 🤣

I was the type of chemistry student that would probably cause an explosion with toenail clippings and water. Yup. I said it. But I love chemistry with a passion and I am really glad I can watch the process from afar. If I was in your lab I'd probably look at something and cause an explosion. Thanks for uploading. Any word on creating Spidey shot yet???

great video, I'd love to see what you'll come up with after further experimenting with it. I am thinking about doing something similar soon

Hi, I'm an automation engineer from India. Many years ago, I have seen colloidal iron produced by electrolysis in a chemical factory. They were using a electrodes of iron to electrolyse caustic soda! I'm not a chemist & that time it didn't strike me about ferro-fluids. But their product was like bright grey-suspended in paraffin-oil. Is there something relevant for you in my observations?

Out of topic but when he got the powder i got an advertisement of simply piano and i got the most wholesome ad i had ever got that had couples involved in it 😭 ❤️

i love this guy

if you're on mobile pause at 2:34 and move your screen around
