It may not make a bomb, but it does make a good bomb detector!
But I think it could, weapon-wise, be used to unleash massive amounts of electricity on people.- sounds great...benfal99
- hey, well there's hardly anything that gets invented that doesn't end up being used as a weapon.sarahfailin

a matter of time before Einstein-2 create the Graphen Bomb. A bomb 100,000x more powerful than the A-Bomb.

Cadmium Arsenide: A 3D Alternative to Graphene That's Way More Useful
There's no denying that graphene is a wonderful material—strong, flexible, and highly conductive—but it's taking a long time to become a commercial reality. Now, scientists working with a material called cadmium arsenide believe it offers many of the same benefits—but could actually be far easier to use in the real world.
Researchers from Oxford, Stanford and Berkeley have developed the new material which they claim "has the same extraordinary electronic properties as 2D graphene, but in a sturdy 3D form" That might not sound like a big deal, but its the planar, 2D nature of graphene which makes it hard to manufacture in bulk and craft into components.
Instead, cadmium arsenide has a 3D crystal structure, and tests show that electrons within it act like they do in graphene—as if they have no mass at all. That's what gives graphene its stunning electrical properties.
A number of samples of cadmium arsenide have been made and tested at the Diamond Light Source in the United Kingdom and at Berkeley Lab's Advanced Light Source, all suggesting that cadmium arsenide behaves like a 3D version of graphene. The results are published in Nature Materials.
The huge benefit is that cadmium arsenide is easier to grow and work with because of its 3D nature. Graphene might have stolen an early lead, but it's going to have to work to keep a hold of it.
- But it's made from cadmium and arsenic...sarahfailin

but apparently you can get it from coal too. the structure is just pure carbon, of which coal is made.another concern though is that to make graphene useful, it will probably be mixed with other rare earth elements like beryllium, which will continue to increase in demand/cost.

Graphite is the 15th most abundant mineral in the Earth's crust and has three forms: diamonds, coal, and graphite. Graphite comes in the form of Carbon (C) and is often denoted as Cg, with the 'g' specifying the form of carbon. Graphite is an excellent conductor of heat and electricity and has the highest natural strength and stiffness of any material known today. It maintains its strength and stability to temperatures in excess of 3,600°. At the same time it is one of the lightest of all reinforcing agents and has high natural lubricity.
There are three types of graphite found naturally; these are flake, lump, and amorphous. Flake graphite commands the highest demand due to the versatility of use yet has the lowest supply. This creates a premium price for flake graphite with larger flake sizes having higher prices than a smaller flake size of equal purity.

It smells like burnt lotion in here.

fuck off science, trying to convince the left-wing hippies that we can save the earth without getting off with trees while listening to dub-reggae through our dreadlocks.

How to make graphene using household items and a kitchen blender.

I've seen graphene made but so far its strength seems like a theory it seems. I've searched around and they are predicting its practical use by 2030
come one people...I want a graphene cell phone now!- er come on...yurimon

i'm down for a condom one atom thick
- what is that? a condom for ants?_niko

Graphene doesn't occur naturally, it has to be produced from sheets of carbon one atom thick.
Methods are being developed to generate graphene faster, but it's currently a lengthy process.It's amazing stuff, but I wonder, given the laws of conservation of energy, if the energy used to create it might negate its benefits (especially in terms of generating charge using water).
As a manufacturing material in the future though, it's very exciting

What about thorium, wasn't that supposed to save us all?

Carbon is most abundant element on planet Earth. No need to worry.
- Humans are made of carbon. They will bomb youukit2
- actually high quality graphite is harder to come by, turns out China has most of the worlds supply_niko
- Yeah, and oxygen is the most abundant element on earth, representing 47% of its mass by weightsarahfailin

someone mentioned graphene here a week or so ago and that was pretty much my response.sad but true, if your country is the only one with graphene, watch the fuck out future terrorists.

one question, who do we have to bomb the fuck out of to get it?
