So cool. As I understood it, graphene had only been manipulated to be in repulsive magnetic states. It really is a wonder that you were so open with your experiments. Where this to have occurred in some other lab, chances are no one would know about it. This is actually a pretty big step I think. How can you use this? What are the applications you have in mind? At this point, I would not fault you for not sharing.
no worries mate - i am thinking of a curie engine - but there is a fair amount of investigation to be done here - to my mind the most interesting thing here is what can be done with simple tools and a spirit of investigation lol
When making permanent metal magnets they pass an electric current through them to align the molecular structure. Maybe the process of making the ink and letting it dry has somehow aligned the molecules in the graphite. This could either be because of the earth magnetic field or some magnetic field around your work bench. One easy way to eliminate the workbench is to paint another peace somewhere else. Just a theory of course :-)
It is YOU// who is Awesome! Dear Duddy :P Really like the fact You've Shared your Ideas about Categorisation of materials. Yes, Amazing that You could obtain magnetism just mechanically. I guess it is indeed about atomic alignment :) Don't stop My Friend! Best Regards, Didier
Hey Rob, interesting find. I was wondering just, to rule things out, if you could test for the presence of iron in the kish powder you started with, since you said it originates in the production of iron. This is just to rule anything out, since I think this is a very interesting find.
Glass balls plus rubber tumbler = Triboelectric disharge through a conductive graphite? Your videos are like CRACK! Keep cranking them out please. I’ve never actually done crack but I do really like your videos. I had a crappy electronics teacher. She always sat on ass.
I remember reading something a bit back and remember it being something to do with how the graphene is produced. www.extremetech.com/electronics/198563-researchers-make-graphene-magnetic-clearing-the-way-for-faster-everything Excellent stuff non the less Robert!
Thats awesome! I would love to figure out how to reproduce these results. Does it work with any source of graphite? If only I still had access to the SEM and TEM at SLCC! I would be thrilled to image the many forms of graphite/graphene/carbon which you have learned to make and use for your devices.
Yeah I was thinking about doing that, I have a few junk drills I can use but what is the best grinding jar for nano particles? Agate/steel is pricey, plastic wouldn't work so I was thinking of making a ceramic jar from a cheap container with agate balls? I read agate was used for graphene.
I have a theory based-upon what research has shown to be the prior causes of magnetism exhibited in graphite: www.iop.org/news/12/jan/page_53593.html When the graphite used in the experiment (like most graphite with impurities) is spun in the 'Ball Mill', Fe particles are moving past the electro-magnetic fields of the machine's motor and my hypothesis is that they have become magnetized. (James Cole was perhaps onto something?...). I'd like to know how the graphite was sourced. And I noticed this video began with a RMS's disclaimer on the many different types of graphite, categories, what it means to be Graphene. And essentially what I gather is that is all comes-down to purity. If ferro-magnetic particles already were present in the graphite powder, then spinning them over-time would cause those particles to allign N-S-N-S.... and result in a cululative-sum magnetic-field of all of those particles at a single-point (like a kitchen-magnet). Assuming that the graphite was tested for purity prior to the experiment and had no ferrous-magnetic material, It would be good to test for magnetism in/near the Ball Mill chamber when the electric-motor is running, or repeat the experiment by hand and not in the presence of EMF. Would be interested in a follow-up to this, really dig RMSs videos as he inspires us to explore and discover. I think a bigger question is can pure Graphene be magnetized (if in the right state, right temp, etc... :). What also comes-out of this is perhaps a method to determine the level of Fe impurity within graphite or perhaps a method to isolate and remove them! Thanks RMS for your spirit for science and discovery, you inspire us all!
It all about purity structure and simplicity mate the graphite tests out at 99.9997% carbon on elemental analysis - provided by the supplier by the way and it's all about us all being involved
Strange ! Perhaps a bit like when you are deforming stainless steel, it also become magnetic ? Deforming Carbon atoms/molecyle chains . . . But who else than you, should make this discovery ? ? ? Thanks for inspiring me :-) You are the best . . . .
crazy if so...I thought this tech could only be created with some highly expensive tools and equipment (and what wizardry they'd carry out to achieve those ) :o so I suppose the mystery is so big that you will have to have it checked :)
Want to run your weird graphite through our mass spectrometer? Or ICP elemental, or HPLC, or NMR? Demonstrate that it lacks all Fe? (It probably does.) Also: www.nature.com/articles/nphys1399
This is amazing! I was messing around with some graphite yesterday to do this same thing.. It would be fascinating to see the structure under an electron microscope! Maybe AppliedScience will have a look if you ship a sample to him.
I've never heard of this before. After watching, I searched "is carbon magnetic" and the first result was this VERY INTERESTING article: www.materialstoday.com/carbon/news/magnetic-carbon/ They are saying, among other things, that graphite which has been irradiated with protons (hydrogen atoms) can have a very high magnetic moment. Here is a computer graphic simulation of doping the carbon lattice with hydrogen: ruclips.net/video/NmPAAo7_xY0/видео.html Great visualization! Maybe there is some "hydrogen doping" going on from just being in air, or your solution, and tumbling. Or maybe it's picking up hydrogen from the rubber... or something from the glass (is it borosilicate?)... or maybe you were right, and it's a result of the physical change. Very interested in hearing results of an analysis of the material. Thanks for another thought-provoking video.
Do magnets pick up the powder itself? Or just the painted paper? Big question: what's the curie temp of your magnetic graphite paper? If it's up in hundreds of C deg, maybe paint it on ceramic, or ceramic fabric. That way it can be heated to where the attraction to magnets disappears. Also, if successfully heated past a temperature where it loses the magnetic attraction, does the attraction-effect reappear when cooled again?
I came across your channel last night around 8pm, instantly I was hooked, enjoyable friendly and educational, I eventually went to bed around 4.30am _ Thank you FWG :-). I was wondering what would happen if graphite was grounded under pressure with hydrogen added, with the possibility maybe of other metallic or magnetic compounds added. What is the result of hydrogen added to graphite or graphene, with or without metallic or magnetic compounds added. What then if it was mixed with your gel to to create a graphene magnetic metallic formula. My questions are endless, inquisitive nature lol
awesome mate - i tend to be a very practical guy and lots of questions are best answered by getting up and giving it a go - i would encourage you to do just that - cheers
You have done a great job making graphene/graphite scientific works accessible to many people. You are a great chemist and excellent educator. Thank you Robert
Hi Robert, I've enjoyed watching your videos for over a year now, and have even tried my hand at a couple of experiments with graphite and graphite oxide. I noticed you're using a Zoom H4n Sound Recorder there, I shoot film and video, and I own two of those. Fantastic choice for a sound recorder! Might I point out that if you're recording in stereo front mode (red LED at the top facing the front face of the unit, then you should rotate the microphone so the screen is facing you. There are 4 microphones in there, both in xy pattern, and the pairs are meant to capture sound in ~45° area in front of it (the back stereo mode is ~120° wide area, so less ideal for capturing a single subject) Also, I understand if you don't want to risk damaging the recorder but the closer you have that thing to your mouth, the lower a gain setting you can set, which will help to cut a lot of the reverberations and echoes from your lab. Cheers!
Robert Murray-Smith well glad to hear it! He has good taste in sound recorders. I don't know what camera you have to record your videos with but if it has an auxiliary mic or line in then you could even run a stereo cable to it from the zoom's headphone jack to save yourself the step of syncing /mixing sounds later when editing your videos. Thanks for all your work sharing all of your experiments and chemistry advice with the world!
Hi RobertJust wondering what difference would it be , being tumbled in a belt driven tumbler . The motor driven tumbler must be bathing the graphite with magnetism from the drive motor underneath the tumbler or it could be an interaction between the graphite particles.Interesting! Thanks for sharing
What comes to mind for me is static buildup during up during the milling. I was working on a material called pvdf, where if you apply a strong electrical field when it solidifies, it aligns the hydrogen and fluorine. It's a bit different, but potentially the static would cause the structure to change such that ferromagnetic properties emerge?
diamagnetic graphite kits are popular on the web. so maybe Rob has synthesized or otherwise mimicked diamagnetic graphite. How in the world to test for a practical theory of this quantum-mechanical phenomenon?!? amyway, just because something acts diamagnetic does not mean it can be magnetized - i wish it could, and i bet there's a small legion of industrialists who wish it too. scalable permanent magnet technologies are a bit rare, and in extreme demand.
As it happened, RUclips put for me next to this video one titled “Hydrogen makes graphene magnetic” by Ivan Brihuega. Made me wonder if for some reason your tumbler got some water or even hydrogen separated from that water to contribute?
Was wondering what 7 years of research later might come up with and I found Interesting research related to this. It appears that ordinarily undetectable trace amounts of iron particles in carbon are pushed closer and closer together by the mechanical process you've performed. The more you compress them the bigger the magnetic field you can create. That's the theory of the research anyways. This of course isn't definitive just interesting that this is still some rather cutting edge research as it relates to the next level of super-computing.
I randomly remembered this topic as I also made some magnetic graphene a few years back (video on my channel) Do you know if there has been any research explaining this phenomenon? I'm kind of leaning towards the theory that there is some iron contamination. In my case the graphene only became magnetic after heating it so maybe some reaction or reordering is necessary.
just gone through some of your videos and a question came up in my mind.1. Why isnt there any supercapacitor or so called Power Bank made out of graphene in the market? It seems the idea was developed since 2015ish and a Chinese corp Dongxu made a prototype on July 2016. Also saw that there are startup cloud funded company such as zapngo and so on (MWC 2016). 2. Continuing to the first question, what is the reason that makes it hard to make it commercialize. It said its cheap and easy to make. 3. According to some research on Graphene battery, Is it possible to make the capacity of the battery 100 times bigger with the same size to lithium battery (aka cellphone batteries)?Thanks Will keep watching
Before the video was over, I realized we need to figure out how to make graphite ever changing! You’re very smart, however I think this is the objective to what you’re trying to do. Due to this fact I came to the conclusion you’re board, stumped etc., As we all are.
I'm guessing the glass balls/rubber and water combo is producing a static charge when agitated over a long time. Graphite being conductive absorbes the charge and orientates itself into grain structure like a heat treating on a metal or the domain's in a magnet which are pretty similar. Once bound into the ink and left to dry, the bunched together masses align naturally and combine to produce a feild? Electric charge in water sounds like hydrogen has something to do with it aswell, usual surprising hydrogen stuff Probably waaaay off but its late and I'm bored 😄
Hi Robert, liked your analogy of chairs...now then, should the Period Table be constructed as a wave function, with elements overlapping each other depending upon a mean distribution of protons and electrons and maybe exotic particles ? just a thought. Tony
I found this video from adding hydrogens to graphene to make it magnetic. Have you tried it on other materials? The cellulose may have weakly bonded hydrogens that were freed up when painted.
If I take a magnetic tray, take some graphite mechanical pencil lead and roll it back and forth, it begins to react with the magnetic fields. I've been baffled since I was a little kid
I have a video unpublished with grapene in dispersion that showed magnetic properties. Not sure how I made that batch but I felt it was small colloidal iron in my water which may have been from the kitchen sink . I have dryer that out now so if I find it and it has magnetic properties I will do a video and publish it . Regards andy
Robertsir, you can speed up the process of magnetizing the graphite by putting cylindric magnet inside the bottle of solution while running it in the ballmill. or you can just make a graphite sheet first and then magnetize it by giving it very high magnetic field. or add hydrogen to graphite as hydrogen has only one electron it will magnetize the graphite. just try it, that's how we make magnets in our industry.
HV arcs on pure carbon electrodes make a black dust that's magnetic. Like transmutation going on? Peeling scotch tape off a smooth surface makes HV under a vacuum and surprise,,,..XRAYS!
Lol, I had the same thought. I couldn't help but cringe a bit every time Robert waved his hands over the cup. However I often drink coffee or tea at my own desk/lab, which also freaks me out a bit (only if I'm doing chem experiments tho), so I can't complain to much!
But even worse than simple proximity? Most of my experimental beakers are actually reused mason jars, and if all the mugs are dirty, I also sometimes drink out of... mason jars! :O yeah not being able to tell the difference between my coffee mug and my reaction beaker is insanity.
Would proximity to the EMF (produced by the ball mill motor) perhaps have a residual effect on the graphite resulting in it's becoming magnetically attractive?
i suppose it might mate - but i sincerely doubt it - the field at that distance would be minute - probably weaker than the emf from the buildings wiring ring
Hmm... Would you try something ? Get a large block of copper and see if your magnetic tissue is repelled. Another thought was that maybe the tissue was charged? Lots of sliding smashing, smearing... maybe it's electro static?
Rob FYI: physicsworld.com/cws/article/news/2016/apr/22/graphene-doped-with-hydrogen-reveals-its-magnetism p.s. on a slightly un-related tangent, have you ever heard of or looked at the Carlos Benitez Patents? You need to scroll to the bottom of the page to see the links. (complete collection) www.tuks.nl/pdf/Patents/Benitez/
I have 5 pounds of magnetic graphite that came from the mine that way. It was originally sent to a Chicago bushing company, but the company closed before it was used. It came from a sealed container, and I've been experimenting with its odd properties. Gotta love nature..
Hi, very interesting. I'm curious as to whether this works with a drum that hasn't been contaminated with copper nano particles :-). My guess would be that the stray magnetic field from the motor inside your machine, is inducing an electrical charge and polarising the graphite. Could you please test the drum with a compass to see if it retains any memory of the magnetic field. Thanks.
mate - just use an occams razor - if you keep it simple it's likely to be true - when you think about what we are doing here you see we are rolling flat sheets around and around - it's more likely we are forming MWCNTs
What you've done, possibly. Introduced hydrogen from ambient air, fluidly charging the solution through aeration. Research points to the atomic charging of mono and meso allotropes of carbon via hydrogen concentrations. Very interesting demonstration!
Murray' is it possible that the electric motor that runs the tumbler could have induced a magnetic field and electrically magnatetized the carbon electrons in the graphite?
That would have been my guess. Or a possibility that Robert has a magnetic polisher or possibly used as a magnetic polisher? I've found on the Internet several tumbler replacement motors have magnetic coils for motors.
After reading an article on the mystery of magnetic graphite, it maybe that the tumbler exposed the iron and titanium in the graphite and it was further magnetized by exposing the iron and titanium to the magnetic field of the electric motor. phys.org/news/2012-01-scientists-magnetic-mystery-graphite.html Another article on magnetic properties of graphene: phys.org/news/2012-01-graphene-reveals-magnetic-personality.html#nRlv
I was just thinking this my self.. The simply solution, should you have time to try it, would be to remount the motor away from the tumbler and see what happens.. I worked with the late Paul Pantone on GEET for many years, there is an interesting magnetic effect that the reactor produces.. geetlife.weebly.com/reacton-rod.html i wonder what would happen if i expose some graphite to a GEET reactor field.
That is very interesting, is the wet "ink" also magnetic, or does that property arise on drying? On the topic of categories, and based on it's structure, how would you categorise the plant metabolite hypericin with it's array of 8 carbon rings, as a form of functionalised graphene?
Not very often an experiment leaves one with a big surprise. That seems to happen to you with great regularity, lol... If you didn't already have enough on your plate...
I always like your show and priceless scientific inputs. I agree with you not all graphite are the same. Actually all have their own personalities. Differ from one source to another. My question for you, magnetic properties you are demonstrating through mechanical agitation may be due to impurities exist in the graphite source?
so this graphite has free electrons orbiting it, but does it still have a low ohm reading? Wondering if this could be used to make magnetically aligned conductive inks
Graphene is apparently composed of two intermeshed triangular sublattices and by selectively doping one or the other sublattice on an atomic scale an exact magnetic field can be established. There is research being done to store magnetic data on layers only two atoms thick. . . Pretty crazy stuff.
A few comments earlier have pointed out link between hydrogen, magnetism and graphene.. well, you do add water when making the ink... if people are interested there is this you tube video: ruclips.net/video/NmPAAo7_xY0/видео.html
Hi Rob, I suggest it is probably a contamination resulting from the milling in contact with ferromagnetic materials (mill parts). Graphites of natural origin certainly can contain iron oxide (magnetite) or other magnetic mineral particles.
So, probably, you just turned it into a mixture of graphite allotropes with high content of rhombohedral one. It is known to be paramagnetic, even ferromagnetic, see www.nature.com/nature/journal/v413/n6857/abs/413716a0.html
had you made sure your ball mill was fully clean? no iron residue remaining in there? assuming not. very interesting. I heard they made graphene magnetic with hydrogen atoms but not by mechanical means
the crystal structure is how I think the carbon must dry in a pattern that lines up letting the force flow freely. Some carbons frozen do opposite reaction great experiment lol might have a lot to do with water and carbon life forms
ah food for thought.... I am still toying with the thought of about nano particles of gold in a magnetic field to create current collectors on the plates of a battery or eesd type application....great work wish I was there.
Robert, remember you have retentive and non-retentive ferromagnetic so, with that piece of magnetic graphite and if you can attract steel or iron it is retentive. Depending whether it is retentive or non-retentive you can experiment with it and lay it on a graphene sheet and then apply voltage to the graphene sheet to see if the piece of magnetic graphite changes back to non-magnetic or diamagnetic graphite.
Being conductive, I wonder if adding current to the stripe will effect the magnetic properties. This could lead to a type of motor. It could be you are adding Hydrogen to the graphite.
5:11 but your graphite is being attracted to the magnet here, not repelled. edit: On a rewatch i think i just got a bit confused coz the video only mentioned diamagnetism, so i thought this was what you were trying to show. If graphite can display multiple different types of magnetism (depending on treatment) then that's extra exciting. Your piece of carbon there seems very magnetic, too magnetic to be paramagnetic, it seems more like Ferromagnetism is at play here. Found this mentioned in _Nature_ sci journal www.nature.com/nature/journal/v413/n6857/full/413716a0.html _"Recent experiments and theoretical studies have suggested that electronic instabilities in pure graphite may give rise to superconducting and ferromagnetic properties, even at room temperature. "_

Brilliant mate, you have me quite curious as to what is going on in there. :)
i think there is rolling of the graphite sheets into what is effectively a MWCNT mate - not much but enough to give a significant response
As it happened, RUclips put for me next to this video one titled “Hydrogen makes graphene magnetic” by Ivan Brihuega. Made me wonder if for some reason your tumbler got some water or even hydrogen separated from that water to contribute?
Was wondering what 7 years of research later might come up with and I found Interesting research related to this. It appears that ordinarily undetectable trace amounts of iron particles in carbon are pushed closer and closer together by the mechanical process you've performed. The more you compress them the bigger the magnetic field you can create. That's the theory of the research anyways.
This of course isn't definitive just interesting that this is still some rather cutting edge research as it relates to the next level of super-computing.
I randomly remembered this topic as I also made some magnetic graphene a few years back (video on my channel)
Do you know if there has been any research explaining this phenomenon? I'm kind of leaning towards the theory that there is some iron contamination.
In my case the graphene only became magnetic after heating it so maybe some reaction or reordering is necessary.
Would the motor impart some magnetism to it?,...I wouldn't think so :-/
it would be highly unlikely mate
just gone through some of your videos and a question came up in my mind.1. Why isnt there any supercapacitor or so called Power Bank made out of graphene in the market? It seems the idea was developed since 2015ish and a Chinese corp Dongxu made a prototype on July 2016. Also saw that there are startup cloud funded company such as zapngo and so on (MWC 2016). 2. Continuing to the first question, what is the reason that makes it hard to make it commercialize. It said its cheap and easy to make. 3. According to some research on Graphene battery, Is it possible to make the capacity of the battery 100 times bigger with the same size to lithium battery (aka cellphone batteries)?Thanks Will keep watching
Before the video was over, I realized we need to figure out how to make graphite ever changing!
You’re very smart, however I think this is the objective to what you’re trying to do.
Due to this fact I came to the conclusion you’re board, stumped etc.,
As we all are.
I'm guessing the glass balls/rubber and water combo is producing a static charge when agitated over a long time. Graphite being conductive absorbes the charge and orientates itself into grain structure like a heat treating on a metal or the domain's in a magnet which are pretty similar. Once bound into the ink and left to dry, the bunched together masses align naturally and combine to produce a feild?
Electric charge in water sounds like hydrogen has something to do with it aswell, usual surprising hydrogen stuff
Probably waaaay off but its late and I'm bored 😄
Hi Robert, liked your analogy of chairs...now then, should the Period Table be constructed as a wave function, with elements overlapping each other depending upon a mean distribution of protons and electrons and maybe exotic particles ? just a thought. Tony
Really helpful...
Anti-P2 best Masters of Work.
Also you look a bit a cross between the old Pope and Antony Hopkins.
Thre real trick would be magnetic diamond. Though that may be only possible if you align the atoms some way.
I found this video from adding hydrogens to graphene to make it magnetic. Have you tried it on other materials? The cellulose may have weakly bonded hydrogens that were freed up when painted.
How bizarre. Can't wait to find out what you've physically changed in that graphite.
If I take a magnetic tray, take some graphite mechanical pencil lead and roll it back and forth, it begins to react with the magnetic fields. I've been baffled since I was a little kid
I have acquired graphite blocks for separating steel. How can I turn this into graphing
could it be you moved thd water molecules fast enough to split into hydrogen and hydrogen enriched graphote is magnetic?
First we invent the nuclear bomb, then later on the transistor, then much later graphene. Are things really out of order ?
Could it have been iron contamination from the ball mill? Is it rubber all the through inside?
I pulverized pencil graphite and the the small granular graphite will stick to a magnet as well.
I have a video unpublished with grapene in dispersion that showed magnetic properties. Not sure how I made that batch but I felt it was small colloidal iron in my water which may have been from the kitchen sink . I have dryer that out now so if I find it and it has magnetic properties I will do a video and publish it . Regards andy
I used DI water mate - so not like - for me - to be colloidal iron - but do the video i'd love to see
Hi sir diamagnetic repel function model any chemicals name sir
Robertsir, you can speed up the process of magnetizing the graphite by putting cylindric magnet inside the bottle of solution while running it in the ballmill.
or
you can just make a graphite sheet first and then magnetize it by giving it very high magnetic field.
or
add hydrogen to graphite as hydrogen has only one electron it will magnetize the graphite.
just try it, that's how we make magnets in our industry.
dunno mate - try it and see
never fail to teach me something, your a diamond Mr Murray
hi where can I buy one of your millinh machines?
HV arcs on pure carbon electrodes make a black dust that's magnetic. Like transmutation going on? Peeling scotch tape off a smooth surface makes HV under a vacuum and surprise,,,..XRAYS!
awesome - i didn't know that
A bit worried your cup O'tea is exposed to all these chemicals :)
you don't need to worry mate - i'm the one drinking it lol
Lol, I had the same thought. I couldn't help but cringe a bit every time Robert waved his hands over the cup. However I often drink coffee or tea at my own desk/lab, which also freaks me out a bit (only if I'm doing chem experiments tho), so I can't complain to much!
But even worse than simple proximity? Most of my experimental beakers are actually reused mason jars, and if all the mugs are dirty, I also sometimes drink out of... mason jars! :O yeah not being able to tell the difference between my coffee mug and my reaction beaker is insanity.
i'm guessing it is a mistake you wouldn't make twice lol
How does it deal with altering magnetic fields?
Would proximity to the EMF (produced by the ball mill motor) perhaps have a residual effect on the graphite resulting in it's becoming magnetically attractive?
i suppose it might mate - but i sincerely doubt it - the field at that distance would be minute - probably weaker than the emf from the buildings wiring ring
Hmm... Would you try something ? Get a large block of copper and see if your magnetic tissue is repelled.
Another thought was that maybe the tissue was charged? Lots of sliding smashing, smearing... maybe it's electro static?
i'll give it a go mate
Rob FYI: physicsworld.com/cws/article/news/2016/apr/22/graphene-doped-with-hydrogen-reveals-its-magnetism
p.s. on a slightly un-related tangent, have you ever heard of or looked at the Carlos Benitez Patents? You need to scroll to the bottom of the page to see the links. (complete collection) www.tuks.nl/pdf/Patents/Benitez/
never heard of them mate - iw ill go and have a look - cheers
Hi Robert, Just found this video. Could it be the hydrogen from the water getting rolled and pressed into the graphene of the graphite.
I don't know mate - maybe
I have 5 pounds of magnetic graphite that came from the mine that way. It was originally sent to a Chicago bushing company, but the company closed before it was used. It came from a sealed container, and I've been experimenting with its odd properties. Gotta love nature..
that is intersting where was the mine located? - have you had any SEM imaging done?
Hi, very interesting. I'm curious as to whether this works with a drum that hasn't been contaminated with copper nano particles :-). My guess would be that the stray magnetic field from the motor inside your machine, is inducing an electrical charge and polarising the graphite. Could you please test the drum with a compass to see if it retains any memory of the magnetic field. Thanks.
mate - just use an occams razor - if you keep it simple it's likely to be true - when you think about what we are doing here you see we are rolling flat sheets around and around - it's more likely we are forming MWCNTs
What you've done, possibly. Introduced hydrogen from ambient air, fluidly charging the solution through aeration. Research points to the atomic charging of mono and meso allotropes of carbon via hydrogen concentrations. Very interesting demonstration!
may well be in part mate - i like the idea here - maybe try it again but introduce an in situ hydrogen source
Murray' is it possible that the electric motor that runs the tumbler could have induced a magnetic field and electrically magnatetized the carbon electrons in the graphite?
That would have been my guess. Or a possibility that Robert has a magnetic polisher or possibly used as a magnetic polisher? I've found on the Internet several tumbler replacement motors have magnetic coils for motors.
After reading an article on the mystery of magnetic graphite, it maybe that the tumbler exposed the iron and titanium in the graphite and it was further magnetized by exposing the iron and titanium to the magnetic field of the electric motor. phys.org/news/2012-01-scientists-magnetic-mystery-graphite.html
Another article on magnetic properties of graphene: phys.org/news/2012-01-graphene-reveals-magnetic-personality.html#nRlv
it is possible i guess
I was just thinking this my self..
The simply solution, should you have time to try it, would be to remount the motor away from the tumbler and see what happens..
I worked with the late Paul Pantone on GEET for many years, there is an interesting magnetic effect that the reactor produces.. geetlife.weebly.com/reacton-rod.html
i wonder what would happen if i expose some graphite to a GEET reactor field.
BigBlueMotors p
That is very interesting, is the wet "ink" also magnetic, or does that property arise on drying?
On the topic of categories, and based on it's structure, how would you categorise the plant metabolite hypericin with it's array of 8 carbon rings, as a form of functionalised graphene?
no idea mate - i just dried it and tried it then shared it. As for the second part I am sorry mate - i have no idea
Not very often an experiment leaves one with a big surprise. That seems to happen to you with great regularity, lol... If you didn't already have enough on your plate...
lol - and i was only mucking about in between things lol
I always like your show and priceless scientific inputs. I agree with you not all graphite are the same. Actually all have their own personalities. Differ from one source to another. My question for you, magnetic properties you are demonstrating through mechanical agitation may be due to impurities exist in the graphite source?
They may well be mate but they are not evident in the base material
That's...quite interesting. I wonder if your Graphite ink has ferro fluid-like properties.
dunno - worth looking at - let me know what you find out
I'm curious as to how you discovered it was magnetic... Do you normally hold magnets near to pieces of carbon?
i was looking for diamagnetism ref to the Sri Lankan Graphite sample
so this graphite has free electrons orbiting it, but does it still have a low ohm reading? Wondering if this could be used to make magnetically aligned conductive inks
i don't know - worth a try
Graphene is apparently composed of two intermeshed triangular sublattices and by selectively doping one or the other sublattice on an atomic scale an exact magnetic field can be established. There is research being done to store magnetic data on layers only two atoms thick. . . Pretty crazy stuff.
yep lol
A few comments earlier have pointed out link between hydrogen, magnetism and graphene.. well, you do add water when making the ink... if people are interested there is this you tube video: ruclips.net/video/NmPAAo7_xY0/видео.html
cheers mate
hey rob how do u test what micron your particles are
Perhaps due to some homopolar electrostatic effect from the surface of the glass..?? My interest is piqued! :)
doesn't seem likely to me mate - i am leaning to MWCNT formation
Hi Rob, I suggest it is probably a contamination resulting from the milling in contact with ferromagnetic materials (mill parts). Graphites of natural origin certainly can contain iron oxide (magnetite) or other magnetic mineral particles.
it's in a rubber container with zircon balls mate
So, probably, you just turned it into a mixture of graphite allotropes with high content of rhombohedral one. It is known to be paramagnetic, even ferromagnetic, see www.nature.com/nature/journal/v413/n6857/abs/413716a0.html
sounds about right - cheers mate
There is also a report about ultrasonic treatment having this effect. I am gonna try it.
awesome - let me know how you get on mate
had you made sure your ball mill was fully clean? no iron residue remaining in there? assuming not. very interesting. I heard they made graphene magnetic with hydrogen atoms but not by mechanical means
it was clean mate
Is it possible you're having iron impurities in the graphite and the act of bonemilling and drying causes the particles to coalesce?
i don't thinks so mate - this is discussed further in the comments section below
the crystal structure is how I think the carbon must dry in a pattern that lines up letting the force flow freely. Some carbons frozen do opposite reaction great experiment lol might have a lot to do with water and carbon life forms
might well do mate
ah food for thought.... I am still toying with the thought of about nano particles of gold in a magnetic field to create current collectors on the plates of a battery or eesd type application....great work wish I was there.
cheers mate - and go for it
thanks for sharing again ur ideas....
just seen a video from about 6 months ago that explains how hydrogen makes graphene magnetic.
seen it too mate - but cheers
What is the device behind you with a dial and piston
I love your Vids. Thanks
Robert, remember you have retentive and non-retentive ferromagnetic so, with that piece of magnetic graphite and if you can attract steel or iron it is retentive. Depending whether it is retentive or non-retentive you can experiment with it and lay it on a graphene sheet and then apply voltage to the graphene sheet to see if the piece of magnetic graphite changes back to non-magnetic or diamagnetic graphite.
good advice mate - cheers
Fascinating as usual. Have you tested it against iron to see if it attracts?
i haven't mate - i should try it
Lightweight motors and maglev trains where the whole structure of the train is a lifting force rather than the lift being a separate system.
could be mate
Any update to this? Any close up photos?
Being conductive, I wonder if adding current to the stripe will effect the magnetic properties. This could lead to a type of motor. It could be you are adding Hydrogen to the graphite.
Wow! Robert you are Super Interesting, wish I could have a few Pints with you, thanks for the excellent Videos.
What is the definition of the binder SPR
Are the graphene/plastic pieces you made (In your video about bulletproof graphene armor) magnetic?
Amazing! What happens if you put the magnet in the graphite ink?
no idea
good video!
Very neat! Great job again, Robert.
cheers mate
nice find Robert. this could open up a lot of possibilities
cheers mate - it is interesting
is it able to withstand high heat?
🤯🤯🤯🤯🤯🤯🤯🤯🤯🤯
i don't know about these things, but doesn't diamagnetism mean it will be REPELLED by a magnet, not attracted?
yes - but that's what i said
5:11 but your graphite is being attracted to the magnet here, not repelled.
edit: On a rewatch i think i just got a bit confused coz the video only mentioned diamagnetism, so i thought this was what you were trying to show. If graphite can display multiple different types of magnetism (depending on treatment) then that's extra exciting.
Your piece of carbon there seems very magnetic, too magnetic to be paramagnetic, it seems more like Ferromagnetism is at play here.
Found this mentioned in _Nature_ sci journal www.nature.com/nature/journal/v413/n6857/full/413716a0.html
_"Recent experiments and theoretical studies have suggested that electronic instabilities in pure graphite may give rise to superconducting and ferromagnetic properties, even at room temperature. "_
yes - i covered this in the video mate - i was looking for diamagnetic but got ferro magnetic
