Hi everyone,I have been trying to help Merfedit with an experiment and found a way to make carbon nanotubes at home by accident!I used a long nose bic lighter for barbecue,butane powered.I bought this one on sale at the store for $2.50.I tried to ignite a piece of borax treated magnesium but the darn(thats D A R N) thing would not light!The yellow flame from the butane lighter was putting soot on the strip of magnesium.So I thought thats the carbon nanotubes there!So I stopped trying to light the magnesium and took voltages.I got .60 volts most of the time and got an amp reading(the highest) of .003 mAs.So my experiment went off in a different direction.This is a success all by itself.I used a piece of my borax treated magnesium,could not light it after two minutes but it got hot and covered with black carbon soot from a yellow flame butane powered bic lighter.They have found nanotubes and buckyballs in soot.I will save this piece of soot covered magnesium and take readings in the days to come.triffid


I get about .002 milliwatts from this one piece of borax treated magnesium strip.
Where I held the strip with pliers theres a clear area.So I put the voltmeter there and on the soot.

http://en.wikipedia.org/wiki/Carbon_nanotube

Nanotubes were observed in 1991 in the carbon soot of graphite electrodes during an arc discharge, by using a current of 100 amps, that was intended to produce fullerenes.[65] However the first macroscopic production of carbon nanotubes was made in 1992 by two researchers at NEC's Fundamental Research Laboratory.[66] The method used was the same as in 1991. During this process, the carbon contained in the negative electrode sublimates because of the high-discharge temperatures. Because nanotubes were initially discovered using this technique, it has been the most widely used method of nanotube synthesis.
The yield for this method is up to 30% by weight and it produces both single- and multi-walled nanotubes with lengths of up to 50 micrometers with few structural defects.[31]

http://en.wikipedia.org/wiki/Soot Soot is a powdered form of

http://en.wikipedia.org/wiki/Amorphous_carbon


Coal and soot are both informally called amorphous carbon. However, both are products of pyrolysis, which does not produce true amorphous carbon under normal conditions. The coal industry divides coal up into various grades depending on the amount of carbon present in the sample compared to the amount of impurities. The highest grade, anthracite, is about 90 percent carbon and 10% other elements. Bituminous coal is about 75-90 percent carbon, and lignite is the name for coal that is around 55 percent carbon.

http://en.wikipedia.org/wiki/Carbon_nanofoam   The nanofoam contains numerous unpaired electrons, which Rode and colleagues propose is due to carbon atoms with only three bonds that are found at topological and bonding defects. This gives rise to what is perhaps carbon nanofoam's most unusual feature: it is attracted to magnets, and below −183 °C can itself be made magnetic.

Well I had read that carbon nanotubes were found in soot.Soot is at the least amorphous carbon and I can apply it to electrodes in my kitchen.If you make a carbon arc with pencil lead you should get some carbon nanotubes(less than 30%).  Its turning out that soot (  amorphous carbon) is ok .Its conductive and may be a way to protect my magnesium strips in the future.As of late last night after the electrode had cooled some I got a max of .25 volts.triffid

The mustard oil used in the experiment was procured from a local market and
of edible quality. Normally vegetable oils contain glycerides of a mixture of sev-
eral types of fatty acids. Mustard oil is comprised of 76% monosaturated, 23%
polyunstaturated and 1% saturated fatty acids like oleic, linoleic, linolenic acids
(all 18-carbon chain with unsaturation) and arachidic acid (20-carbon chain, satu-
rated). Burning of other edible oils do produce soot of interesting properties (under
investigation), but mustard oil was selected ¯rst because it contained very high un-
saturated fatty acids among all the available, commonly used edible oils, and for
its low cost. The raw soot was collected by burning mustard oil with the aid of a
cotton piece in insu±cient air


So one could soak a cotton ball in pretty much any cooking oil.lit it on fire,drop it in a jar and close the lid
to get soot.

My strip of magnesium metal with soot on it is still producing voltage. Where the layer of soot is thickest,I get the strongest voltage readings.I can get .59 volts where the carbon layer is thickest.Where I got .6 volts yesterday (before the strip cooled down) And where its thinner I can now get .15 volts.There is a bead of carbon on the backside of the strip and thats where I get .59 volts today.triffid

There is no water in this reaction.Except for water in the air.I have a battery from a single strip of metal!I tried putting soot on copper(no voltage was observed).Black copper oxide is not conductive.So that may have been the problem?triffid

This is a repost of mine mostly for Murfedits benefit.

Let me say something here.Putting these cells together requires quite a bit of skill using the materials we have available to us in the kitchen.While I can look at the catalogs on laboratory glassware and dream of paying out 150 dollars to 200 dollars for some really neat looking glassware.I know I really can't afford that.So I go to the grocery store ,buy cottage cheese and yogurt in plastic containers.That I can wash out and use for my experiments.I can buy applesauce in glass jars or pickles in glass jars.Wash those out and save them to use in my experiments.I can buy corn dogs and save and wash those wooden sticks to stir with or if they are flat like mine are.I can use them as a measure.So today I realized as I was treating my magnesium strips with borax that I was using stuff from the grocery store to work with.

low cost lab equipment to work with .plastic bottles to mix salt solutions with too.

Now I will add a little more to because I learned from Murfedit a little more.You can use scissors to cut out aluminum pop cans and plastic bottles to make low lying containers to put your stuff in.I have made funnels from plastic bottles and a sheet of paper(that was from me).
Now Murfedit uses plastic bottle caps as a base for his alligator clips(a trick I had never heard of before).Just a reminder that you don't have to buy expensive glassware to do your experiments with.triffid

Yesterday I measured the voltages on my soot partially covered piece of magnesium metal.My voltages were a lot lower.I could only get .015 volts max where I had .6 volts the first day and could only get .040 volts max on the bump of carbon on the backside where the day before I could get .59 volts.Of course these are maximums.Most of the times the voltages were lower but not zero!triffid

Different days give me different readings on my magnesium/carbon soot battery.Today I got max readings of .029 volts frontside and .116 volts backside.I will try to get a picture of this over the weekend.triffid

Hi Triffid,


I see you're getting some low voltage from your new cell. Try recording the voltage of the cell and then hook the cell up to a capacitor and let it charge the capacitor. Try to use something like a 1uF capacitor. Let it charge over night and see if the voltage go up higher than they normally do.




Why I say this is that I have a crystal pressure cell that i let live in oil. I have had other crystal pressure cell placed in oil but what made this one different was that it wasn't allow to age like the other cells before placing it in the oil, as soon as this cell was made i put it in the oil. Well the cell look like it was performing nicely like the others. These pressure cells will start of at 1.3 volts and then go down to around 300mV and then climb back up to 1.1 volts. This pressure cell that was put in the oil right away went down to 200mV and stayed there, at first i thought it was dead but I was wrong! In-fact this cell is far from dead. This cell is playing possum. If i hook it up to a meter it will read around 200mV but that doesn't mean nothing. If i hook a capacitor up to it and allow it to charge the capacitor over night it will charge the capacitor beyond 1.2 Volts!


So to make this clear my crystal pressure cell is at 200mV, but hooking it up to a capacitor that is empty it will charge that capacitor beyond 1.2 volts. That is over a volt increase. Now the big question is ---- Where did this extra energy come from?  :o  How can this be possible? a 200mV source can charge a capacitor beyond 1.2 volts, no circuits involved just a straight hook up to the capacitor.


This has gotten me so confused. This would be like a AA battery at 1.5 volts being able to charge a capacitor up to 2.5 volts, this would be impossible but yet my cell is doing this. I have run this test many times and i get the same result. I first used a 1uF capacitor that had less that 50mV in it and it was charged to 1.2, almost 1.3 volts the next morning. The cell had only 200mV in it when i mearsued it the next morning. I also removed the capactior and shortd out all day and when i came home from work i hook the cell back up to the capacitor and let it charge over night and i got the same results. So to make sure it was not a fluke I grabbed a 220uF capacitor that had at the time more voltage in it than in the cell, capacitor had 250mV and the cell was 202mV. I let it charge over night and now it is at 1.183 volts.


Its like the cell has more potential energy than what the multi-meter can read and the capacitor can see it just fine and is able to charge to that level. The meter sees only 200mV but the capacitor sees 1.2 volts. This is a odd thing to see.
