Graphene Under Strain Creates Gigantic Pseudo-Magnetic Fields

Yup.

Just like they did with the 200 mpg carbeurator!

Sorry about the triple post, I’m having some computer issues.

Well, that and the platinum coated chickenwire.

One does wonder what this thing cost ! $19.98 ~ not sold in stores.

There are some other uses of very powerful pseudo magnetic fields ~ e.g. antigrav units!

I wonder if we could make electric guitar strings out this stuff.

Hmmmmm...think of the output of a pickup with this stuff used as the magnet. You'd only need a few windings, making for a very compact pickup. In theory, of course.

"antigrav units"

Can't wait 'til they come out with the AntiGravJordans.

White men will be able to jump!

[muawiyah]

You mean, of course, the neighborhood kid's S-10 pickup TRUCK where he's replaced the passengerside with a soundsystem.

Doggone, he could get his seat back ~ and make that baby buck like the world's most powerful Low Rider!

BTW, this, of course, means that the Chicom miniature speaker industry is now KAPUT!

How long before EPA declares it to be a pollutant and tries to limit it.

You’ve got it decimon, pseudo-automobiles produced by GM (government motors).

Once bHo gets energy cost to skyrocket, we can use pseudo-dollars to buy pseudo-cars running on pseudo-electricity.

We can even have a pseudo-Constitution...oh wait, we already have that.

[GOPJ]

Does this have anything to so with an anti-gravity look-alike?

[Traveler59]

Understatement of the year award. Nothing about reverse EMF toasting breakers, EMP killing equipment, or the startling noise and flash.

Not to mention the laundry bill for anyone in close proximity. :)

Yeah, if there is no ACTUAL magnetic field produced then the discovery is of little use ... but it is interesting.

[decimon]

Yes, but strumming will pull the fillings out of your teeth.

I dimly remember one of my company’s scientists had a project to use powerful magnetic fields to affect the rate of radioactive decay in nuke waste. He said he could hasten the half life to make it give up it’s energy much faster. This could provide a usable energy source while destroying nuke waste.

Dunno if it worked.

Thanks decimon! There is a surprising number of topics about graphene here on FR. :') Burnt City still roooools though. ;') Carbon nanotubes conduct electricity at low resistance, carry metal molecules along for the ride.

...pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory -- just by putting the right kind of strain onto a patch of graphene. "We have shown experimentally that when graphene is stretched to form nanobubbles on a platinum substrate, electrons behave as if they were subject to magnetic fields in excess of 300 tesla, even though no magnetic field has actually been applied," says Crommie. "This is a completely new physical effect that has no counterpart in any other condensed matter system."

For example, in strong pseudo-magnetic fields electrons orbit in tight circles that bump up against one another, potentially leading to novel electron-electron interactions. Says Crommie, “this is the kind of physics that physicists love to explore.”

But the kind of English that grammarians love to deplore.

[aruanan]

This may well solve the problem of the energy required to maintain a magnetic bubble around a fusion reaction.

Around a pseudo fusion reaction.

Pencil-necks and graphite just go together. ;-)

[Quix]

IIRC,

THAT’S DINKING AROUND in the area of UFO type technologies.

. . . both in terms of the graphene as well as the results.

[SunkenCiv]

I’m sure someone has named their daughter graphene by now.
