Modern day’s cold fusion, lot of hot air but never delivers

[Seruzawa]

I’mgetting dizzy. We need to ban hyphenated names. I couldn’t get past Dresden-Schnitzel.

A charbroiled sausage.

[SolidRedState]

Wow! Exactly what I thought.

You win!

Sorry, bombarding carbon with xenon atoms stripped of up to 35 of their electrons makes me really geek out. I wish I were there.

Once again, graphene has proven itself to be a rather special material:

...

For researchers it is. As far as commercial applications go, it’s a dud.

An amazing element, carbon!

No wonder the Demwits are trying to outlaw it...

Thanks for posting! ;)

Where do these replacement electrons come from? That’s something that I’ve always wondered, even with photoelectrics: The photon drives off electrons to generate a current, but the silicon remains. HOW? Where do the “new” electrons come from?

[AFreeBird]

A brat? What beer goes with that?

[2ndDivisionVet]

A tiny black hole?

[Husker24]

Mixed with plastic it’s incredibly strong, bullet proof.

“As far as commercial applications go, it’s a dud.”

But I want a million watt graphene tube guitar amp!

Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K'. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Four electronic properties separate it from other condensed matter systems.

[Moonman62]

Is it sold anywhere for that purpose?

[Company Man]

Femto’s, is that like Fembots?

How can I decipher all of what you said? Can I ask Meryl Streep or Tom Hanks? They're always talking like they know stuff. /s

(I was an IT engineer for decades before retiring, was asked by receptionists and others if they could get my job after taking a course or two at the local community college. I would laugh in their faces, and say no...)

[Paladin2]

Isn’t “Yuge” now a technical/scientific term?

As far as commercial applications go, it’s a dud.

Not really, graphene based products are already hitting the market:

"Turnigy Graphene packs utilize carbon in the battery structure to form a single layer of graphene just 0.335nm thick, making that type of battery substrate the thinnest known to mankind. The graphene particles form a highly dense compound allowing electrons to flow with less resistance compared to traditional Lipoly battery technologies. The result is a battery capable of maintaining greater power output whilst remaining much cooler under load. Since heat and resistance are the natural enemy of batteries Graphene chemistry has significantly reduced these problems and the result is an incredible boost in cycle life. Turnigy Graphene batteries are the new standard for serious hobbyists who require POWER ON DEMAND."
