Graphene - unexpected science in a pencil trace: Dr Aravind Vijayaraghavan at TEDxOldham

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 wonder if, instead of filtering vodka, this could be used to filter sea water to make it drinkable? This is fascinating stuff!

    What is the potential of the future graphene industry to be a carbon sink?

    Just another storyteller. You need to be doctor for this speach. Remarkable.

    I don't mean to be too particular but a fullerene is any perfectly formed carbon nanotube or buckyball, also known as cylindrical fullerenes and spherical fullerenes.

    Does it mean that anything more than one atomic layer stops being graphene? What is the physical tangibility of one atomic layer? It would be invisible, unhandleable, untenable. Even edible silver foil (put on top of Indian sweets) disintegrates to the touch even though it is many microns thick. Would a single-atomic-layer graphene coating on any physical surface that one is seeking to strengthen hold together? Puzzled.

    the wave forms in the frequencies of graphine radio waves too lazor waves the measure is in this pair of angles that reflect the signature so there not to far from it gassess used by Tesla and the florescent bulbs and the in fer red test tubes he made from gassess.

    Cheapest component for creating graphene is hemp. It creates the perfect nano-tubes.

    So u mean it's even better then graphite..? I thought you had to use that and process graphene from it..?

    Something doesn't track, if it won't pass helium, how does it filter water?

    Good question! Pure graphene will not let water through either as you expect, but it needs to be engineered with narrow pores for this purpose. It turns out we can engineer the pores just big enough for the water molecules to pass through leaving behind all the salts.
