- In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
I'm learning more about the vaccine everyday
Frightening!
The beauty of this Ted Lecture is that the fellow presenting a very complex idea, does so in very straight forward and simplify's the idea. This man has the gift for presenting new information in a way that many can understand. Many professors speak in way's that information is presented in a complex manner.
""Playing with their new toy!!! Wow!! Now people are getting sick and not making it!!! Wow!!"""
One of the best videos about graphene so far. He explained it very clear and thorough.
It's as 2D as something can ever be. It has the height of one atom. Since charge is carried by the electron the single atom thickness is only going to allow that charge to move in 2 dimensions But it is a 3D object.
That view of graphene is dependent on the atoms-are-marbles view of physics. In fact, quantum mechanics treats atoms as distributions of excited wave functions above a local ground state. So a more field-theory type viewpoint is that atoms, by virtue of being excitations in an underlying potential field, lose their geometric sense of "length, breadth, height". Thus, you might say atomic particles in some sense are dimensionally indefinite, and the dimensions we experience are macro scale effects of many such atoms coming together, not unlike temperature, wetness, or friction. So if the scientific community finds it fit to view graphene as a 2-dimensional structure, I'll let 'em have it. I understand how trivial concepts like length, breadth, and height can mess with ones sense of how the quantum world behaves. To end, the classical viewpoint would correctly contend that graphene is 3-Dimensional, but then again, classical physics is inadequate for our description of this 21st century wonder material. I only have a limited understanding of quantum field potential theory, so my explanation of dimensions may be a little off, but I mean well and wish you the best as you continue to explore the fascinating world of carbon's graphene. Greetings from Michigan!
Fantastic presentation...
At 4:40 The Enterprise hails his communicator!
Kirk hails Vijayaraghavan at TEDx Manchester
The material Graphene is really fantastic and should be researched in scientific manner. Scientific method is based four principles 1)Observation 2)Measurement 3)Experimentation and 4)Good thinking. The number 4 is most important because the present problems in World are mainly because of ignoring or overlooking impacts on nature and environment but giving importance to Money oney. The excessive mining of sand for construction purpose is burning issue and research in developing suitable material using Graphene will be a great help. Eliminating plastic will be also great achievement.
Can Graphene be programed to carry out different task?
Hope graphene membranes will improve filtration in dialysis machines and help kidney patients
Wow, indoctrination at it's finest
Cool presentation 👍🏻
So our electrons (3d) can move in all direction
Can Graphene replace silver in the electronics industry ?
No. This is underlying carbon tech re: higher elements like silver, titanium, silicon or copper. Gateways will need to be developed to interface w/ current tech and materials.
so that means that a smartphone made mostly of graphene would be transparent?
Probably.. the future is so bright I have to wear shades.
Why is graphite so weak if it’s made out of graphene?
I think it's because microscopically it is made of millions and millions of individual flakes of graphene all piled on top of each other. The individual flakes are quite strong but the composite structure is weak.
Bonding... maybe
Nice..
He sounds likes raj from big bang theory
Which is close to true... except graphene is real world. ;)
And "Big Bang" theory [NOT the tv show ] isn't real world?
This is the future the 2D is endless its mother nature talking to mankind elementary
it is chemically inert except when?

15:20 he said faster to DISCHARGE... Shouldn't it be slower to discharge.
The faster you can discharge a battery, the more usable current you can draw at any time via the fast discharge, so you can run greater loads. In short it makes for a more usable battery.
Firearm development . Light weight gun barrels (rifles etc etc).Missiles.Space booster rockets.

Hey arvind I'm from india
graphene is 3d ! the thickness of an atom is a measured amount,thus making it a 3d object !
this needs to be in phones!!!
G5. Please research its safety.
Seems to me that time is of the essence in getting graphene into markets and commerce asap. Americans are quickly losing the technology advantage they once enjoyed at height of auto-piston engine era. We need those graphene engines, motors, batteries, solar panels, Pre-fabed homes, hospitals ASAP x ASAP Squared! What's the hold up? Capitalist political ideology; that's: "what's the hold up"!

2014…
CARBON, coal dust. say no more, I feel another carbon credit scam coming.
Why would graphene be used in medicine?
Do you not do independent research? For 2 years now the proof has been exposed, not on the tv, you have to go to the "conspiracy theorists" to get the truth. Why is that you ask? Go research the Smith Mundt act and how Obama amended it so msm and the gov can lie to and spread propaganda to Americans.
Layer upon layer of ultra-thin nanomaterials is the makeup of the alien implants pulled out of people by dr. Rodger Leir.
This guy doesn't grasp the concept of graphene, who put him on the stage smh
i swear, TED will let just about anybody up there on stage regardless of oratory eloquence
We prefer to focus on substance rather than eloquence
