honestly Robert Your an amazing smart man and i would of been honored to have you as a teacher / tutor at uni or college they way you speak so passionately about your work and how it fascinates you its inspirational , honestly Robert you should think about getting paid to be a teacher people like yourself need to be in the schools because the passion you have and how you describe your work and findings is just brilliant and spectacular , just makes me feel the passion and the excitement and why i love technology and how stuff works and is made , you Sir are a Brilliant inspiring man

When you look at the extent that Tech Ingredients went to in order to achieve the same thing it boggles the mind why this video has less than 30,000 views and theirs has 1.3 million views.

The secret to Roman concrete was discovered IRC 10 to 20% calcium oxide addition to the mix of portland cement this lets the concrete heal cracks as the oxide absorbs carbon IMO the combination of the two graphene and calcium oxide would be amazing.

You just gave me an easy way to strength aircrete for offgridvhome building! You just blew up my channel!

I LOVE kitchen/backyard science. It's the foundation of humanity's curiosity.

Robert, I would like to express my utmost gratitude for your unwavering dedication and meticulous research. Thanks to your invaluable contributions, I have achieved a significant milestone by successfully synthesizing graphene oxide for the first time, and subsequently transforming it into graphene using your recommended techniques. Your enlightening videos have truly acted as a gateway to the vast realm of inkjet printed electronics, significantly propelling my research forward. With great anticipation, I eagerly await any future uploads from you, as each video is a treasure trove of knowledge and never fails to captivate and inspire me. I extend my heartfelt appreciation for your remarkable efforts and, above all, for the profound knowledge you have bestowed upon us regarding graphene throughout the past decade. As an inventor and KZfaq blogger, you remain an unrivaled figure in my eyes. Keep up the good work my friend!

A couple things from the Kitchen Chemistry 101 paper that I may have missed from the video, but may help others if left out: They used DI water with a PH of 7, which the PH of 7 gave the best exfoliation rate of PH 1 to 9 tested. From what I can assume, a centrifuge was used to speed up the graphite separation. Just let it sit for a few hours/days if you don't have one (or like Robert said, just use the solution as is), and the graphite will settle on it's own.

since we can make graphene using light, and we can make it from blood, plus the hint in the intro to this video, i think robert is suggesting vampires with their readily reactive nature when exposed to sunlight, is the best source of graphene when bombarded with a uv laser

It would make aircrete strong enough to pour a dome home foundation with! This so so crazy!

Very nice, thanks for unearthing & sharing this gem. It does feel like we're on the cusp of a tremendous breakthrough on very high volume production of useful graphene synthesized at stupendously low cost with widely available raw materials. The challenge will then be taking it in its raw form and tailoring to the specific application. And who knows, maybe this IS one of those breakthrough methods where this is the bulk graphene platform and the challenge is now ours to do the tailoring for integration into specific applications. Anyway, many thanks.

Not much a believer, but today, with this video, I see the light! Thank you so much, you delightfully brilliant and hilarious gentleman. I needed this, especially after seeing the Tech Ingredients tests.

I read the paper about milk proteins and graphene. It should be noted that the researchers stopped blending every 5 minutes to slow down the heating and take samples. Don't just blend for 30 minutes straight.

I will try that when I can get caught up on everything I need to get done. Thanks Robert, that's great.

You always bring something amazing. Thank you.

Thank you Robert! My poor Hubby is Scared of this!! So, I'm going to have a go at this myself! Amazing video as Always!! Thank you Robert and this Community here who are very encouraging and helpful!! Andréa and Critters. ..XxX...

All I can think of to say, is " *BRILLIANT!!* " Thank you for the video!

this is amazing! you are the most amazing teacher i ever had

Excellent stuff, thank you!

You're a genius Rob! Thanks for sharing this one :)

@Robert Murray-Smith - I must say I thoroughly enjoy all the work you do and effort you put into your videos. I look forward to see each new one you publish... Today, I probably watched this video for the 4th or 5th time as I am really inspired by this. I hope to learn more of this method of making graphene and you said that the graphene is protein coated. If I may ask a question, for normal graphene applications such as structural enhancement in plastics, concrete etc. would you need to somehow remove the protein from the graphene? If so, how would someone do it?

Perfect! Thank you!

To turn the mixture into a graphene solution capable of exfoliation (separating graphite into graphene sheets), several additional steps or modifications are typically needed beyond simple blending at room temperature. Here's how you could approach it: 1. Strong Acid Treatment: Introduce a strong acid like sulfuric acid (HSOz) or nitric acid (HNO3) to the mixture. This acid treatment helps to oxidize and intercalate (insert between layers) the graphite particles. 2. Ultrasound Treatment: Apply ultrasound energy to the acid-treated mixture. Ultrasound waves can help to further exfoliate the graphite layers, breaking them down into thinner graphene sheets. 3. Centrifugation: After ultrasound treatment, centrifuge the mixture. This separates out larger graphite particles and allows the graphene sheets to remain dispersed in the solution. 4. Rinsing and Neutralization: Rinse the dispersed graphene sheets with water to remove excess acid. Neutralize the solution to ensure it is safe for handling. 5. Characterization: Characterize the resulting graphene solution using techniques like scanning electron microscopy (SEM), atomic force microscopy (AFM), or Raman spectroscopy to confirm the presence of graphene and assess its quality.

Can’t believe you failed to celebrate your successful recipe with a ‘whey hey!’.

Woooo! This is great! Makin graphene in the kitchen! Thanks!

best channel on youtube imho

Thank you very much.

Brilliant. Cheap and easy. Would be fine to hear results of conductive coating this way

Robert YOU Are UNBELIEVABLE 😁👍

Facinating. Thanks for the video!. So i have no clue about what graphen is used for.

Why can’t you just evaporate out the water instead of having to centrifuge it to separate it?

Id love it if you could do a full course of “From novice to Robert Murray-Smith Level” of videos detailing how to get to your level of expertise. Id pay good money for such a course.

Amazing!

Episode 1933, Rob finally goes mad DOCTOR MURRAY

Hi there, love your videos and was curious after watching this one if you think you could you use acetone 3:1 to both capture the graphene in solution and separate the proteins and excess graphite? Then you could just filter the solution? Cheers from N.Z

So i tried this with clay instead and did a control too. Looks like it working, the clay and water only already has about an inch of clay settled on the bottom, but the one with whey has a very thin layer that is grey in color, (using terracotta clay, might be impurities or excess whey not sure), the layer with the suspension i can't see any distinct particles, its just one solid color like a pudding cup in appearance. I wanted to try this since suspended nanoclay is used to treat sandy soils like in dessert (or in my case Florida), to improve it's water and fertility holding capacity. Normally the clay will just deposit on the surface if it's just water and clay, hopfully with the whey it will be able to soak in, I got two fish tanks im gonna use to compare.

H2SO4 and sugar make some sort of graphite. Blend it with blood and voila. Ox blood is incidently an excellent paint used throughout middle ages, as well as floor material if mixed with dirt.

Just a thought , could you soak an ore/iron steel silver copper gold aluminium bronze brass etc in this and when smelted / heated , the water would evaporate leaving the ore coted in the Graphene ? Or using a different oil based medium or a power moulding system add to resins or plastics or fibbers making them stronger ? or add to battery chemicals to make a more conductive stronger /more powerful battery ? As always a huge fan of all you are doing . Keep up the good work cheers

How does this method compare to the ball bearing and glycerine method you did a couple years ago? Does it have a higher yield? Is it cheaper?

Really cool, the milk method. I needed an excuse to purchase a blender for my shop anyhow. Made a batch, spread it out, dried it. That was June. Long busy summer, just went to go back to tinkering with graphene, and something completely unanticipated had happened. Mice ate my graphene. I guess I should have expected that something food based would attract mice, so my bad that I didn't put the product into a sealed container. I'm sitting here looking at hundreds of mouse droppings which are jet black. I never would have guessed it. Time to make a new batch.

Brilliant.

Any advice on how much of the graphene mixture to mixture to add to concrete? If we had one bag of dry mix would the entire water content want to be the graphene mixture or just a smaller portion?

So can I use this graphine to coat the glass on the thermal vacuum tube to make a proper cup?

I was thinking about composite materials. It would be nice to coat a graphene-enriched resin epoxy on a piece of extruded polystyrene. Robert do such an experiment and present ours. I don't have graphene. Thank you brother!!!

What amazes me is graphene which is almost innert could have so many uses. It seems it would almost be well trash.

I gave this a try today - I will update with results. Interestingly, the paper said they stopped the blending often to keep the bulk temperature below 30 C. Rob, did you do this or just keep the blender running for 30 minutes? I've tried to do both, but it will be a couple weeks before I can comment on if it makes a difference with concrete hardness

You address a bit of this in another video, but: You've got graphene with whey protein isolates cladding the faces of the 'sheets'... And you impregnate the casein from milk to make a very tough plastic material... Would it not make sense to: 1. Coagulate the milk, reserving the solids as part B and the liquids as part A 2. Make graphene as you do it here, BUT! use the part A liquids that you've just made 3. Spin off your newly made bio-compatible graphene powder 4. Add this to your part B casein 5. Compress In this manner you're not buying already-isolated whey and adding water to it, you're simply removing the casein which you will then use anyway. Are the concentrations high enough? This would effectively halve the number of steps in the process, make it even cheaper, and potentially for the enterprising dairy farmer reduce the equipment outlay. I would love to know your thoughts

Instead of buying whey powder, would you be able to use the whey you produced when making casein on the second part? I just don't know how much that would affect the water to protein ratio

Great video, thanks. For concrete making what is the benefit of whey over washing up liquid? Is the washing up liquid not compatible with concrete?

You made graphene infused bioplastic today, I don't have a blender but would love to be able to experiment with these myself. Will a high enough concentration of graphene per casein be conductive enough to replace copper(or gold or silver) sheeting? or is does the casein act as an insulator? could you press and heat it in thin enough sheets to use as circuitry if you adhere it to a board? also, there was a man studying graphene tubes in china. he fed them to silk worms and tested the silk they produced. the silk became conductive and much stronger. could it be possible to adhere this protein covered graphene to silk that's already been processed into thread? I'm really just discovering my interest in electricity and the like and don't have all the principles mastered. Would using more wires, of thinner diameter in a generator that used to contain standard 14ga or whatever, be more efficient? or would the increased resistance just set it on fire? Thank you for making all these fantastic videos. I'm a new fan, and you will soon be getting at least one more view and like on videos 1 through 1934.

Now THERE'S a use for the whey left over from the cheese and yogurt making!

Can you demonstrate a strength test by mixing it with epoxy resin, and then applying pressure

Does the urea mix work in the blender rather than the ball mill do you think? And if you were adding it to hdpe or resin i assume youd need to get it to powder form? Im definitely going to try this in a couple aircrete experiments- thank you!

Rober you remind me of the professor on Gilligan island. If you were stranded i could see you making a radio and batteries abd fans and even make-up for Ginger. I dont know if you saw the show but we use science in everyday things but we have no idea on how to make it or apply it.

This reminds me of a science article on using blood to make concrete stronger

can you mix it with plastic, like PLA?

Do you have to use a centrifuge, or, could you possibly filter it out of the water using a gravity filtration set up, maybe, using a vacuum beneath too?

Correct me if I'm wrong, but doesn't graphene/graphite, a carbon, turn into hydrocarbon when in contact with water (so coal)?

So, what if you could get human albumin? Comes in either 4%x 500mls or 20%x 100mls any better than haem in whole blood? Just wondering Cheers

Would it be possible to just evaporate the water to extract the graphene instead of waiting for it to settle? Or would that cause some kind of deproteinization?

Have you put this in paper pulp and cardboard yet? And clay ceramics?

I a thought for direct application, would mineral spirits be a good substitute for the water (at least in some percentage) to allow the mixture to be more easily sprayable ?

Question: how would using the liquid whey byproduct from making diy butter work vs powdered whey?

Can a washing machine spin dryer be converted to filter the Ink for drying? Where can I get a filter bag that size? What type of filter bag is needed?

Graphene from blood?? BRUTAL!

Quick question: is the leftover liquid from making your casein usable as a source of the whey for the graphene production? Because I can't find whey for less than ~ 60c/oz [which works out to ~ $22/kg] and most of *that* is flavoring agents & sugar from the "bodybuilding food" it's sold as, so that's probably what, $100/kg for the actual whey content? It would be aces if the same milk used to produce your own casein biopolymer served double duty for the graphene production...

I wonder if we can make microchip or at least micro circuit with the laser method. Microchip making is the one thing that still teether us to external sources.

If you could also use sausages and beans, you would be able to produce graphene from a typical english breakfast. Who would have thought? Er... I forgot the bacon

do you think the deionized water is necessary?

Could you use your laser method to make the graphene in that method and then use this method to separate it?

I have a funny feeling milk is going to get scarce.😅 I have a small request. But first I will share that I am new to your channel, chemistry, and lab technique altogether. As far as kitchen chemistry goes, I can’t even make a respectable loaf of bread. I am getting better though it requires repeated attempts. 😅 With all that mentioned, here is my request or ask: please, will you demonstrated how you get the graphene out from the container. I would most likely botch the job by accidentally pulling the remaining graphite from the bottom. Maybe you already showed the technique for this on previous videos. Please reply with the video on how to do this. Thank you.

Take a look at “ Daniels Inventions , endless heat 2.0”. Would love to hear what you think and could you improve on it. I have built a couple of your heaters, work well. I am restoring a 75 year old kerosene heater. Thank you for your time and consideration.

Hey bud, i got into the idea of graphene a couple years ago, but i have no way of testing my graphene to know if it is in fact graphene. I dropped charcoal briquettes made for hookah into water, it broke up into a fine material, i strained it through a coffee filter and let it dry. I have a video on my channel. There was a chemical reaction, i figure if this is not graphene mixing some hydrogen peroxide into the solution should break it apart into even smaller materials. Or use ultrasound The plan is to use it in a powder coating gun and spray an ionization pad for an atmospheric generator. How do i check my material to know if it is graphene with out an electron microscope?

So can you just dehydrate it and chuck the powder into epoxy or the like? The whey proteins don't interfere with the graphene properties? What if you burned off the whey proteins, say hit the powder with a torch, will that mess up the graphene?

So using the soapy graphene in foam concrete would improve the strength? If so then adding in fiberglass it may be a usable building material.

Anybody ever tried this sheer method using plain carbon/charcoal? I'm wondering if it could produce something conductive from cheap/free carbon sources (like the charcoal left over from a wood gasifier stove)

unless it is that cheap to get. where do get or find graphite?

Thats Whey Cool! I think i'll give it a whirl.

How much does it improve the strength of concrete and at what ratio? How does it effect the hygroscopic nature of concrete? will Graphene effect long term stability of concrete? Where can I find answers to these questions?

Hi Robert !!! ... Can work with only albumina? .Sorry my English, its poor .. very poor.

What would happen if you create a "settling pond" with the liquid as dispersed as surface tension would allow?

Will ultrasonic bath have the same effect as blender? I have both, but use blender for food, and definitely don't want to introduce any graphene into my diet

I loved the video. I see potentially an issue with using a blender and not ending up with very much single layer graphene as a product. I think this could be greatly improved by using a vacuum ball mill to do the shearing. Doing it under vacuum would eliminate the turbulence induced in the solution. By removing the percolating effect of the air in the chamber, theoretically it would allow for more shearing action by decreasing the disturbance from bubbles migrating through the solution and popping.

Please do Roman concrete with graphene next like one of the comments was talking about

Reading the paper, I believe the centrifuge was used to separate the leftover graphite from the solution. I could be wrong though. That particular sentence was worded a little oddly.

Just had a thought. I've seen roman concrete recipes that involved an amount of pig's blood. It actually did something chemically in the mixture that was measurable but I can't for the life of me remember what it was. That opens some weird research angles.....

You can technically make graphene from any carbon source - the quality is the issue. You can make graphene from peanut shells, fish heads, spiders, horse semen, buffalo scrotums, weasels kidneys, turtle brains, sloth ears, kangaroo eye lashes etc. You get the idea

Just what we needed- graphene improved vampires! Now not only will they sparkle, but their skin will be a beast to pierce- as if they weren't enough of a nightmare to take down before... lol

Two vampires where talking about their friend Egor. “Yeh, he’s always experimenting.” The other vampire agreed adding. “He found out you could make Graphene using blood but he could never get it to work!” “Yes, I heard” said the first vampire. “The problem was that he kept drinking the blood!”

Sir i made a dry graphene using amonium sulfate into distilled water by using electrochemical exfoliation method now i want to make graphene conductive ink and i wnat to increase suspension of ink for long periods kindly guide me i need your guidance thank you

I don’t have the centrifuge. Blender I got but I wonder how an ultrasonic cleaner. Like the one they use to make liposomal vitamin C. Liposomal graphene absorbed into the bones gets the wolverine properties going ;)

I can't wait to use this to make graphene-infused waffles

Funny! Just got a transfusion yesterday!

During watching this I got real excited about all kinds of ideas. Have you ever tried putting the graphene in thermoplastic (like Instamorph and Polyplastics) or bioplastic (milk and vinegar)?

Already have a co2 Lazer scriber in my Amazon cart.

Great stuff. I wondering how such graphene can be added to resin to allow it to be printed in a resin 3D printer? Instead of water, could another solvent be used that is compatible with resin so it can be mixed in? Alternatively do you think the process of mixing dry graphene with resin could be done without it becoming super complicated?

mmm graphine battery

I have to wonder if this could be mixed with chemicals and nefariously put on unknowing people to do all kinds of damage particularly after the fact and from afar. Sounds crazy but I've seen things that might be explained this way

Where can I buy a ton of graphite for $350? I'm seeing prices on the order of $20/lb ($40,000/ton)

what if we replaced water with acetone? then we would have a suspension ready to be used as per your video on how to make graphene filled plastic

Anyone like to share where they get their quality graphite powder from? I mean eBay quality doesn’t seem to be cutting it anymore haha
